Technical Field

[0001] The utility model relates to the technical field of surge protectors, in particular to a split-type intelligent surge architecture. Background Art

[0002] Surge protector, also called lightning arrester, is an electrical device designed to provide safety protection for various electronic equipment, instruments and communication lines in buildings. Surge protector is mainly installed in low-voltage distribution cabinet (box). When the distribution circuit or communication line in the building suddenly generates a peak current or voltage due to external interference, the surge protector can conduct and shunt in a very short time, thereby avoiding the damage of the surge to other equipment in the distribution circuit.

[0003] In the use scenario of multiple surge protectors, the current surge protectors communicate with each other through power line communication (PLC) carrier to transmit their status to the control terminal. Since PLC communication is too sensitive to interference, and there are often various electrical devices on the low-voltage power lines, which will cause different noise and impedance effects on the power lines, thereby affecting the accuracy of signal transmission; on the other hand, when the surge protector is used in remote areas, PLC communication will not be applicable.

[0056] Embodiment 1:

[0057] In this embodiment, a split-type intelligent surge architecture is proposed, such as Figure 1a As shown, it includes multiple backup protection modules 4, surge modules 2, intelligent modules 3, overcurrent transformers 20, leakage current transformers 21 and communication modules 6, one end of the backup protection module 4 is respectively connected to the voltage lines of different phases at the input end of the electronic equipment, the other end of the backup protection module 4 is respectively connected to the voltage input end on the surge module 2, and the other end of the surge module 2 is grounded; the overcurrent transformer 20 and the leakage current transformer 21 are stacked on the grounding copper bus 24 in the surge module 2, and the overcurrent transformer 20 and the leakage current transformer 21 are also respectively connected to the intelligent module 3; the intelligent module 3 is also connected to the voltage lines of different phases at the input end of the surge module 2; the communication interface on the intelligent module 3 is connected to the communication interface on the communication module 6, and the communication module 6 is used to communicate with the control terminal.

[0058] Reference Figure 1aIn this embodiment, multiple functional ports are directly integrated on the intelligent module 3. The multiple ports on the intelligent module include L1, L2, L3 and N, which are respectively connected to the voltage input end of the surge module 2. Ports L1, L2, L3 and N are also connected to the overvoltage detection module 32 (see the following embodiment for details) inside the intelligent module 3; the intelligent module 3 also integrates J1 and J2 interfaces, which are used to connect to the overcurrent transformer 20 in the surge module 2. The J1 and J2 interfaces are connected to the overcurrent detection module 31 inside the intelligent module 3 (see the following embodiment for details); the intelligent module 3 also integrates J3 and J4 interfaces, which are connected to the leakage detection module inside the intelligent module 3 (see the following embodiment 2 for details); the intelligent module 3 also integrates 485A and 485B interfaces, which are used to connect to the communication module 6, and the intelligent module 3 and the communication module 6 communicate via RS485. In one embodiment, the communication module 6 is G340-4GDTU. The power supply terminal of the communication module 6 is connected to 220V AC. For the specific structure and working principle of the surge module 2 and the smart module 3, refer to the following embodiment.

[0059] In this embodiment, the surge protector is separately designed into a surge module 2 and an intelligent module 3. The intelligent module 3 is designed separately, and the state of the surge module 2 is obtained through the intelligent module 3, and then the state of the surge module 2 is transmitted to the communication module 6. The information collected by the intelligent module 3 is obtained through the communication module 6, and the information collected by the intelligent module 3 is transmitted to the control terminal by wireless transmission. At the same time, the control terminal can also send commands to the intelligent module 3 by wireless transmission, and then transmit the corresponding commands to the intelligent module 3 through the communication module 6, which can solve the problem of unstable signal transmission caused by PLC communication. In addition, this embodiment is also suitable for lightning protection projects in remote areas.

[0060] Embodiment 2:

[0061] Next, the surge module 2 will be described in detail. In this embodiment, a surge module for a surge protector is proposed, such as Figure 1As shown, it includes: a protective spring piece 22, an incoming line terminal 23, a grounding copper busbar 24 and an impedance unit 25; one end of the protective spring piece 22 is set as a fixing part 220, and the other end is set as a fuse part 221, and the structure between the fixing part 220 and the fuse part 221 can be deformed under the action of external force; the fixing part 220 is fixed on the incoming line terminal 23, and the fuse part 221 is welded to one end of the impedance unit 25; the other end of the impedance unit 25 is connected to the grounding copper busbar 24, and the grounding copper busbar 24 is grounded; the incoming line terminal 23 is used to be connected to the alternating current of different phases in the electronic device respectively, and the protective spring piece 22 has a tendency to move upward so that the fuse part 221 is separated from one end of the impedance unit 25 when the voltage is abnormal.

[0062] When an electronic device is struck by lightning, it may cause voltage anomaly. Of course, other factors may also cause voltage anomaly. This embodiment mainly discusses voltage anomaly caused by an electronic device being struck by lightning. Voltage anomaly refers to voltage exceeding a preset value.

[0063] The surge module 2 proposed in this embodiment is used in a surge protector. The surge protector is usually connected to the input end of the alternating current of the electronic device. The alternating current includes three-phase lines U1, U2, and U3 and a neutral line N. Therefore, in one embodiment, referring to Figure 1 The surge module 2 includes four protective springs 22 and four incoming line terminals 23 .

[0064] The protective spring 22 is made of conductive material, and can be made of 304 stainless steel with nickel plating on the outside. After the fixing part 220 is fixed on the incoming terminal 23, since the protective spring 22 is elastic, when welding the fuse part 221, it is necessary to press down the protective spring 22 until the fuse part 221 is connected to the impedance unit 25, and then perform welding operation on it. At this time, the protective spring 22 has upward kinetic potential energy. When the voltage passing through is too high, the welding position of the impedance unit 25 and the fuse part 221 heats up, the solder joint falls off, and the fuse part 221 is separated from the impedance unit 25, causing the protective spring 22 to bounce upward. This design enables the protective spring 22 to quickly disconnect the circuit when the voltage is abnormal, thereby protecting the electronic equipment.

[0065] The incoming line terminal 23 is used to connect the surge protector to the power line of the electronic device. Since the electronic device usually uses three-phase alternating current, the incoming line terminal 23 is designed to be connected to the power line of each phase respectively. The grounding copper bar 24 is a copper component with good electrical conductivity, which is used to connect the fuse 221 of the surge protector to the ground signal, wherein the grounding copper bar 24 can also be replaced by other conductive conductive sheets. Overvoltage can be released to the earth through the grounding copper bar 24, thereby protecting the electronic device from damage. The impedance unit 25 is used to provide a certain impedance under normal working conditions to limit the flow of current. However, when the voltage exceeds the set threshold, it allows overcurrent to pass, thereby triggering the fuse of the protective shrapnel 22.

[0066] Next, other structures on the surge module 2 will be described.

[0067] In one embodiment, the impedance unit 25 includes a plurality of varistors, one end of each varistor is welded to the fuse 221 , and the other end of each varistor is connected to the grounding copper bus 24 .

[0068] The resistance value of the varistor will change with the change of voltage. In a surge protector, the function of the varistor is to rapidly reduce the resistance value of the varistor when the voltage flowing through it exceeds a set threshold (for example, 660V, that is, the breakdown voltage of the varistor in this embodiment is set to 660V), thereby allowing overcurrent to pass and triggering the protection mechanism.

[0069] Specifically, one end of the varistor is welded to the fuse 221, and the other end is connected to the ground copper bus 24. The reason for this design is that when the electronic equipment is struck by lightning or other situations where the voltage is too high, the voltage will rise rapidly and exceed the set threshold. At this time, the resistance value of the varistor will drop sharply, allowing current to pass through to absorb the surge generated by the lightning strike in the circuit, thereby protecting the electronic equipment from damage caused by the surge generated by the lightning strike. The continuous flow of current will cause heat. When the heat reaches a certain level, the fuse 221 of the protective shrapnel 22 will detach from one end of the varistor, blocking the flow of current to prevent the surge module from continuing to heat up and causing dangerous events such as fire.

[0070] In one embodiment, the surge module 2 includes a total of 8 varistors, with two varistors forming a group, and each two varistors are connected in parallel between the fuse 221 on the protective spring 22 and the grounding copper bus 24 to better achieve the above functions.

[0071] In one embodiment, a structure of the fuse 221 is as follows: Figure 2aAs shown, under this structure, when welding the fuse part 221 and the varistor, there are two welding methods: the first welding method is to usually press the middle part of the protective spring 22 first, and use a welding gun to spot solder at the center of the fuse part 221. The solder will automatically flow to both sides under the action of gravity, and then wait for the solder to cool before releasing the pressed protective spring 22 to complete the welding of the fuse part 221 and the varistor. That is, under this structure and welding method, there will eventually be two welding points a and b between the fuse part 221 and the varistor; the second welding method is to spot weld the two sides of the fuse part 221 and the varistor respectively, and spot weld the gap between the fuse part and the varistor on both sides, and finally form two welding points.

[0072] The first welding method is to automatically flow the solder to both sides until the entire fuse 221 is welded to the varistor. The solder has uncertainty when flowing. Since the fuse 221 is welded between the two varistors, the solder that reaches the gap between the varistors and the fuse 221 on both sides may be uneven. The second welding method may also result in uneven solder on both sides of the fuse 221. The uneven solder on both sides of the fuse 221 will affect the welding effect of the fuse 221. Under the elastic force of the protective shrapnel 22, the welding is unstable, that is, when a lightning strike occurs, the welding point between the fuse 221 and the varistor heats up. Under the same heating time and the same heating temperature, if the solder between the two sides of the fuse 221 and the varistor is uneven, it may result in one side of the fuse 221 being separated from the varistor, and the other side of the fuse 221 being not separated from the varistor. This will cause the instability of the entire surge module in subsequent work, leading to the occurrence of safety accidents.

[0073] In order to solve the above problems, and to better weld the fuse 221 to the varistor and quickly separate when the current is too large, as shown in FIG. Figure 2As shown, the fuse part 221 includes two lower folding structures 2210 and an upper folding structure 2211; the upper folding structure 2211 is welded between the pins of the two varistors, and the two lower folding structures 2210 are arranged on both sides of the upper folding structure 2211. There is a gap between the lower folding structures 2210 and the lower folding structures 2210, and the pins of the varistor are embedded in the corresponding gap. Among them, the inflection point of the upper folding structure 2211 is located between the two varistors, and the lower folding structure 2210 is buckled down on both sides of the pins of the varistor, and then welded. This design reduces the cross-sectional area of ​​the end of the fuse part 221, reduces the impedance of this part, makes the temperature higher when the current is too large, and is more convenient for the fuse part 221 to separate from the varistor. The advantage of this design is that due to the large impedance of the protective spring 22, when the current exceeds the maximum discharge current, the fuse 221 can quickly generate a large amount of heat, causing the fuse 221 to break or causing the low-temperature welding point between the fuse 221 and the varistor to melt, thereby cutting off the circuit and improving the overall safety performance of the surge protector. In one embodiment, the downward folding angle of the downward folding structure 2210 is 38°-42°. After many experiments, the welding effect and the decoupling effect (that is, the fuse 221 is separated from one end of the varistor) of the downward folding angle of the downward folding structure 2210 in this range are better. At the same time, by Figure 2 When welding the fuse 221 with the structure of , first press the upper fold structure 2211, then spot weld the lower fold structures 2210 on both sides and one end of the corresponding varistor, and then spot weld the two sides of the middle upper fold structure 2211 with the varistor, which is more conducive to stability after welding. The advantage of this structure is that under the corresponding welding method, there are at least 4 welding points between the fuse 221 and the varistor. When an overcurrent flows through, causing the two welding points on either side of the fuse 221 to melt, the two welding points on the other side cannot withstand the elastic force of the protective spring 22 itself after being heated, and will be disconnected, so that the entire fuse is separated from the varistor, ensuring the stability of the surge module 2.

[0074] In one embodiment, a surge protection module such as Figure 3a As shown, it includes an incoming copper bar 1', a first module pin 2', a second module pin 3', a tripper 4', a tripping copper bar 5', an outgoing copper bar 6', a spring 7' and a color indicator 8', and its connection relationship is as shown in FIG. Figure 3aAs shown, no further introduction is made in this embodiment. Its main working principle is to introduce a copper bar 1' and connect it to one phase of the three-phase live wire. The first module pin 2' and the second module pin 3' are conductive inside the surge protection module. By welding one end of the trip copper bar 5' to the second module pin 3', welding the other end of the trip copper bar 5' to the lead-out copper bar 6', and grounding the lead-out copper bar. After welding, the trip copper bar 5' will press against the release 4' diagonally upward. The release 4' is a special shape. Pressing the trip 4' upward will pull the spring 7' upward, and the color indicator 8' will be blocked. At this time, the color indicator viewed from the viewing angle can be green; as shown in FIG. Figure 3b As shown, when the temperature is too high, the solder between the second module pin 3' and the trip copper bar 5' melts and detaches, and the solder between the other end of the trip copper bar 5' and the lead copper bar 6' melts and detaches. At this time, the trip copper bar 5' no longer applies a force diagonally upward to support the tripper 4', and the spring 7' contracts to pull the color indicator 8' downward, revealing the color indication inside. For the purpose of warning, the inside can be set to red, that is, when red is observed through the observation angle, the surge protection module has been unhooked and needs to be repaired or replaced.

[0075] like Figure 3a The surge protection module shown in the figure requires manual observation of the color indicator 8' to determine whether it is tripped after the trip copper bar 5' is tripped, which is inefficient and inconvenient for real-time monitoring, and is prone to potential safety hazards. Figure 3 , Figure 4 and Figure 5 As shown, the surge module 2 also includes an overcurrent decoupling protection device 26, and the overcurrent decoupling protection device 26 includes a trigger switch 260 and a trigger circuit board 261. The trigger switch 260 is arranged on the trigger circuit board 261, and the trigger circuit board 261 is used to connect with the control module 30; the trigger switch 260 is relatively arranged on the protection spring piece 22, and when the fuse part 221 is separated from one end of the impedance unit 25, the protection spring piece 22 is used to trigger the trigger switch 260, so as to monitor whether the protection spring piece 22 is separated from the impedance unit 25 through the control module 30.

[0076] When a decoupling event occurs (i.e., the fuse 221 is detached from one end of the impedance unit 25), the protective spring sheet 22 pops up, and the protective spring sheet 22 presses against the switch pin of the trigger switch 260 (i.e., Figure 3 The trigger switch 260 is switched from an open state to a closed state.

[0077] In one embodiment, four trigger switches 260 are provided on the trigger circuit board 261, and the four trigger switches 260 are connected in parallel, that is, when any trigger switch 260 is closed, it will inform the control module 30 that a decoupling event has occurred. In one embodiment, the model of the trigger switch 260 is KW12-5A, 10T85, HK-04G-LZ-019 or HK-04G-LZ-004. It is mentioned above that the protective spring sheet 22 has a tendency to move upward after welding. When the current is too large, the welding point between the fuse 221 and the varistor melts, and a decoupling event occurs. Since the trigger switch 260 and the protective spring sheet 22 are relatively arranged, the detached protective spring sheet 22 will bounce upward to trigger the trigger switch 260. After the trigger switch 260 is closed, it will generate a corresponding electrical signal to the control module 30. Reference Figure 3 A connection socket L305 is provided on the trigger circuit board 261, and the connection socket L305 is electrically connected to the four trigger switches 260: the plug J305 is plugged into the connection socket L305, and the plug J305 is also connected to the control module 30, so as to transmit the electrical signal to the control module 30, and then the control module 30 converts the decoupling event into a corresponding signal and transmits it to the control terminal to generate a corresponding warning signal to remind the management personnel to repair or replace the surge protector in time. The specific signal transmission method will be described in the following embodiments, and will not be described in detail in this embodiment.

[0078] During the use of the surge protector, overcurrent and degradation may occur. In either case, the entire surge protector needs to be inspected and the entire structure or some components replaced according to the fault. Therefore, in order to know whether these two situations occur, in one embodiment, Figure 6 As shown, the surge module 2 also includes an overcurrent transformer 20 and a leakage current transformer 21; the overcurrent transformer 20 and the leakage current transformer 21 are stacked on the grounding copper bus 24. The output end of the overcurrent transformer 20 and the output end of the leakage current transformer 21 are respectively connected to the control module 30. The stacked arrangement means that the two transformers (i.e., the overcurrent transformer 20 and the leakage current transformer 21) are arranged up and down, so that the installation space can be saved more without interfering with each other.

[0079] The overcurrent transformer 20 is used to generate a first induced current and transmit the first induced current to the control module 30 to monitor whether the surge module 2 has an overcurrent. The leakage current transformer 21 is used to generate a second induced current and transmit the second induced current to the control module 30 to monitor whether the leakage current of the surge module 2 is within a preset range.

[0080] Among them, on the one hand, when the surge protector is struck by lightning, the overcurrent transformer 20 is used to monitor the current in the circuit (i.e., the surge module 2). The overcurrent transformer 20 usually has a high sensitivity and can respond quickly when the current on the surge module exceeds a set threshold to generate a first induced current.

[0081] On the other hand, during normal operation, the leakage current on the surge protector is generally less than or equal to 0.5μA. If the leakage current is greater than 10mA, it is determined that the performance of the surge protector is reduced and deterioration has occurred. When the leakage current is greater than 20mA, it is determined to be a failure and a new surge protector needs to be replaced in time. The leakage current transformer will generate a second induced current according to the leakage current on the surge protector, and the control module 30 will know whether the leakage current on the surge protector is within the normal range according to the second induced current.

[0082] The control module 30 is used to detect the first induced current and the second induced current to determine whether the current surge protector has overcurrent and leakage. The specific detection method and the corresponding structural design will be described in detail in other embodiments, and will not be described in detail in this embodiment.

[0083] When the surge current in the surge protector exceeds the maximum discharge current, the welding point of the fuse part 221 and the impedance unit 25 can quickly generate a large amount of heat, causing the low-temperature welding point to melt and break, thereby improving the safety performance of the surge protector. In this embodiment, by setting one end of the protective spring 22 as the fixed part 220 and the other end of the protective spring 22 as the fuse part 221, the structure between the fixed part 220 and the fuse part 221 can be deformed, and the fixed part 220 is fixed, and the fuse part 221 is welded to the impedance unit 25, it can be achieved that when a large current appears on the protective spring 22 in an instantaneous short circuit, the middle part of the protective spring 22 has an upward displacement trend, and can be better fused, so that the fuse part 221 is separated from one end of the impedance unit, so as to prevent the surge module 2 from overheating and causing dangerous accidents.

[0084] Embodiment 3:

[0085] The following description will be made in conjunction with specific circuit examples to explain the contents of the solution. However, as a person skilled in the art, the circuit in the corresponding drawing should not be regarded as the only way to implement the technical solution of the utility model, but the core utility model idea of ​​the utility model should be condensed therefrom. The circuit structure within a reasonable range extended on this basis should be recognized as within the protection scope of the utility model.

[0086] In Example 2, a surge module for a surge protector is proposed. In this embodiment, the intelligent module 3 is introduced. The intelligent module 3 includes a monitoring circuit for a surge protector and a corresponding circuit board. The monitoring circuit is used to monitor the state of the surge module 2 in Example 2, such as Figure 7 As shown, the monitoring circuit for the surge protector includes: a control module 30, an overcurrent detection module 31, an overvoltage detection module 32, a leakage detection module 33 and a communication module 34; the overcurrent detection module 31, the overvoltage detection module 32, the leakage detection module 33 and the communication module 34 are respectively connected to the control module 30.

[0087] Combination Figure 6 The input end of the overcurrent detection module 31 is connected to the overcurrent transformer 20, and the overcurrent detection module 31 is used to receive a first induced current and output a corresponding level signal to the control module 30 according to the first induced current; wherein the first induced current is the current generated by the overcurrent transformer 20 after the surge module 2 is struck by lightning.

[0088] The input end of the overvoltage detection module 32 is respectively connected to the surge module 2 (such as Figure 1 The control module 30 is connected to a voltage input terminal of the control module 30 for receiving voltages of different phases and outputting corresponding level signals to the control module 30 according to the voltages of different phases.

[0089] The leakage current transformer 21 (such as Figure 6 As shown) is used to receive a second induced current, the output end of the leakage current transformer 21 and the voltage input end of the surge module 2 are connected to the input end of the leakage detection module 33, and the leakage detection module 33 is used to output a corresponding level signal to the control module 30 according to the second induced current; wherein the second induced current is the current generated when the surge module 2 leaks.

[0090] The control module 30 is used to generate corresponding control signals according to different level signals, and transmit the control signals to the control terminal through the communication module 34 to monitor the status of the surge protector.

[0091] The monitoring circuit of the surge protector is used to monitor the state of the surge protector and ensure its normal operation. The monitoring circuit includes multiple modules, each of which has a specific function and works together to provide comprehensive protection. The control module 30 is the core part of the monitoring circuit, which is used to process signals from the overcurrent detection module 31, the overvoltage detection module 32, the leakage detection module 33 and the communication module 34. The control module 30 will generate corresponding control signals according to these level signals, and transmit the control signals to the control terminal so that the control terminal can obtain the working status of the surge module 2.

[0092] The overcurrent detection module 31 is used to detect the overcurrent generated by the surge module 2 after being struck by lightning, and convert the first induced current generated by the overcurrent transformer 20 into a level signal, and transmit it to the control module 30. The overvoltage detection module 32 is used to detect the voltages of different phases. According to the detected voltage, the overvoltage detection module 32 will output the corresponding level signal to the control module 30, so that the control module 30 obtains the voltage value of each phase, and determines whether the voltage exceeds the threshold according to the voltage value of each phase.

[0093] The leakage current transformer 21 is used to generate a second induced current, and the leakage detection module 33 outputs a level signal to the control module 30 according to the second induced current. The control module 30 will timely obtain the leakage status of the surge module 2 according to the level signal, and replace or repair the surge module 2 in time, which will be described in detail below. The leakage detection module 33 also includes the functions of ground loss detection and decoupling detection, which will be described in detail below.

[0094] The function of the communication module 34 is to transmit the control signal generated by the control module 30 to the control terminal. In this way, the control terminal can monitor the state of the surge protector and make adjustments or alarms when necessary. In one embodiment, the communication module 34 can transmit the control signal to the control terminal by wireless communication. The advantage of this communication method is that there is no need to lay other lines for communication and it is not restricted by the working distance. Through the above design, the control terminal can fully monitor the state of the surge module 2 through other structures of the monitoring circuit, and quickly trigger the protection mechanism when necessary to ensure the safe operation of the electronic equipment.

[0095] Next, the structure of the monitoring circuit will be described in detail.

[0096] In one embodiment, Figure 8As shown, the overcurrent detection module 31 includes a rectifier unit U200, a surge suppressor D200 and a first photoelectric coupler U201; the input end of the rectifier unit U200 is connected to the output end of the overcurrent transformer 20, the output end of the rectifier unit U200 is connected to the two ends of the surge suppressor D200, and the output end of the rectifier unit U200 is also respectively connected to the positive and negative electrodes of the diode in the first photoelectric coupler U201; the emitter of the transistor in the first photoelectric coupler U201 is grounded, and the collector of the transistor in the first photoelectric coupler U201 is connected to the control module 30.

[0097] The rectifier unit U200 is used to convert the first induced current into a direct current signal, the surge suppressor D200 is used to clamp the voltage of the direct current signal below a preset value, and the first photocoupler U201 is used to output a first high-level signal to the control module 30 according to the direct current signal to trigger the control module 30 to obtain an overcurrent event occurring in the surge module 2.

[0098] Among them, the rectifier unit U200 is used to receive the first induced current through the J302 interface corresponding to J1 and J2, and rectify the first induced current to rectify the first induced current into direct current. Among them, in addition to the failure of the electronic device itself, it can be considered that the overcurrent of the electronic device is generally caused by lightning strikes. Therefore, when struck by lightning, the overcurrent transformer 20 will generate a first induced current. By obtaining the first induced current, the number of times the electronic device is struck by lightning can also be counted, specifically including the overcurrent transformer 20 generating a first induced current, detecting the first induced current, and if a specific waveform after the lightning strike is detected in the first induced current, recording a lightning strike count, so as to count the number of lightning strikes. Counting the number of lightning strikes can be used to count the weather conditions in the area where the surge module 2 is set, and to make corresponding countermeasures. The surge suppressor D200 is used to clamp the voltage of the first induced current after rectification into direct current, that is, to meet the working voltage range of the diode in the first photocoupler U201, so as not to break down the diode in the first photocoupler U201; the first photocoupler U201 is used to generate a level signal according to the first induced current, and transmit the level signal to the control module 30. The specific implementation method is implemented according to the characteristics of the photocoupler itself, and will not be described in detail in this embodiment.

[0099] In one embodiment, referring to Figure 6 and Figure 8, the overcurrent transformer 20 will continuously generate the first induced current, and the working principle of the overcurrent detection module 31 includes: the overcurrent transformer 20 outputs the first induced current, the first induced current is rectified into direct current by the rectifier unit U200, and then the voltage is clamped by the surge suppressor D200, and output to the diode in the first photoelectric coupler U201, thereby triggering the transistor in the first photoelectric coupler U201 to output a high voltage, wherein the level signal SPD_PE_OverCurrent_PB0 is connected to the corresponding pin on the control module 30 (see the following introduction for details), so that the control module 30 is aware of the occurrence of the lightning overcurrent event. More specifically, for other structures in the overcurrent detection module 31, see Figure 8 , no further explanation will be given in this embodiment.

[0100] In one embodiment, Fig. 9 , Fig.10 and Fig.11 As shown, the overvoltage detection module 32 includes a second photoelectric coupler (U202, U203 and U204), the positive electrode of the diode in the second photoelectric coupler (U202, U203 and U204) is connected to the neutral line of the input end of the surge module 2, and the negative electrode of the diode in the second photoelectric coupler (U202, U203 and U204) is used to be respectively connected to the phase voltage line of the input end of the surge module 2; the emitter of the transistor in the second photoelectric coupler (U202, U203 and U204) is grounded, and the collector of the transistor in the second photoelectric coupler (U202, U203 and U204) is connected to the control module 30.

[0101] The second photoelectric coupler (U202, U203 and U204) is used to output a second high level signal to the control module 30 when an overvoltage occurs on the phase voltage line, so as to trigger the control module 30 to obtain an overvoltage event.

[0102] The monitoring circuit includes three overvoltage detection modules 32 for detecting voltages of three different phases, that is, the present embodiment includes three second photoelectric couplers (U202, U203 and U204 respectively), and the collectors of the transistors in the three second photoelectric couplers (U202, U203 and U204) respectively output level signals SPD_L1_OverVoltage_PB1, level signals SPD_L2_OverVoltage_PB3 and level signals SPD_L3_OverVoltage_PB4 to the corresponding interfaces on the control module 30 to respectively detect whether the voltages on the first phase voltage line, the second phase voltage line and the third phase voltage line are overvoltage. When the voltage on a certain phase detected by the overvoltage detection module 32 exceeds 621X (1±10%) V, it is in an overvoltage state. For more details, see other structures in the overvoltage detection module 32. Fig. 9 , Fig.10 and Fig.11 , no further explanation will be given in this embodiment.

[0103] In normal operation, the leakage current on the surge module 2 is generally less than or equal to 0.5μA. If the leakage current is greater than 10mA, it is determined that the performance of the surge module 2 is reduced and degradation has occurred. When the leakage current is greater than 20mA, it is determined to be a failure and a new surge module 2 needs to be replaced. The leakage current transformer 21 generates a second induced current according to the leakage current on the surge module 2. In order to obtain the magnitude of the leakage current in the surge module 2 in real time, in one embodiment, Fig.12 As shown, the leakage detection module 33 includes a leakage detection unit, and the leakage detection unit includes a first operational amplifier U300A and a second operational amplifier U300B, the positive input terminal of the first operational amplifier U300A is used to receive a reference voltage, and the reverse input terminal of the first operational amplifier U300A is connected to the output terminal of the leakage current transformer 21; the output terminal of the first operational amplifier U300A is connected to the positive input terminal of the second operational amplifier U300B, and the output terminal of the second operational amplifier U300B is respectively connected to the reverse input terminal of the second operational amplifier U300B and the control module 30.

[0104] The first operational amplifier U300A is used to receive the second induced current and amplify the second induced current. The second operational amplifier U300B is used to further amplify the second induced current and output a third high level signal to the control module 30 to trigger the control module 30 to obtain the occurrence of a leakage event.

[0105] In one embodiment, Fig.13As shown, the leakage detection module 33 also includes a leakage protection unit, which includes a transistor Q300 and an electromagnetic relay RL300; the base of the transistor Q300 is connected to the control module 30, the emitter of the transistor Q300 is grounded, the collector of the transistor Q300 is connected to the negative input terminal of the electromagnetic relay RL300, and the positive input terminal of the electromagnetic relay is used to receive an input voltage; the output terminal of the electromagnetic relay RL300 is connected to the output terminal of the leakage current transformer 21.

[0106] The control module 30 is used to send a leakage protection trigger signal to the leakage protection unit after a preset interval, and the electromagnetic relay RL300 is used to open the detection channel of the leakage current transformer 21 so that the leakage detection unit can detect the leakage current of the surge module 2.

[0107] Among them, Fig.14 As shown, the leakage detection unit also includes a reference voltage generating unit, which is used to generate a reference voltage. The reference voltage generating unit includes a voltage stabilizing source U301, a resistor R307, a resistor R308 and a resistor R309. The reference voltage is the voltage value of the voltage dividing point between the resistor R308 and the resistor R309. The calculation formula of the reference voltage Vref is Vref = 2.5 + R309 / (R308 + R309), wherein R308 is the resistance value of the resistor R308, and R309 is the resistance value of the resistor R309. For the specific structure of the reference voltage generating unit, see Fig.14 , no further explanation will be given in this embodiment.

[0108] In one embodiment, referring to Fig.12 , Fig.13 and Fig.14 The working principle of the leakage detection module 33 includes:

[0109] Reference Fig.12 Since the J3 interface and the J4 interface are connected to the leakage current transformer and the control module 30 respectively, when a lightning strike occurs, the lightning will be indirectly introduced into the control module 30 through the leakage current transformer 21 and the J3 interface and the J4 interface, causing the control module 30 to be damaged by the lightning breakdown.

[0110] In order to be able to remotely detect whether the leakage current on the surge module 2 is within the qualified range, and to prevent lightning from damaging the control module and its peripheral circuits, the weather forecast information of the area where the surge module is set can be obtained in advance. When the weather forecast information corresponding to the installation area of ​​the surge module 2 is obtained as no probability of thunder, the control terminal controls the control module 30 through the communication module 34 to send a level signal SPD_PE_LeakCurProtect_PB6 to the base of the transistor Q300 in the leakage protection unit at every preset time interval (for example, 1 hour), and the 2nd and 3rd ports, or the 6th and 7th ports, on the electromagnetic relay RL300 are respectively connected Fig.12 The J3 interface and the J4 interface in the circuit are respectively connected to the output end of the leakage current transformer 21. The electromagnetic relay RL300 actually acts as a switch. The on and off of the transistor Q300 is controlled by the level signal SPD_PE_LeakCurProtect_PB6 to control the switch of the electromagnetic relay RL300. The switch of the electromagnetic relay RL300 affects whether the second induced current can flow into the leakage detection unit. In the default state, ports 2 and 3, or ports 6 and 7 on the electromagnetic relay RL300 are in a closed state, the second induced current received from the J303 interface is looped back to the ground, and the leakage current detection unit cannot collect the leakage current; when the leakage current needs to be collected, the control module 30 sends a level signal SPD_PE_LeakCurProtect_PB6, the electromagnetic relay RL300 is turned on, the leakage current detection unit takes effect, and the leakage current is collected. The collection process is to convert the second induced current of the leakage current transformer into a voltage signal, which is then amplified by the first operational amplifier U300A, and then in phase with the operational amplifier U300B, and finally outputs the level signal SPD_PE_LeakCurrent_PA0 to the control module 30, so that the control module 30 obtains the leakage current of the surge module 2 at this time. In one embodiment, when the leakage current is not collected, the level signal SPD_PE_LeakCurrent_PA0 is output as a reference value (such as 3.3V). When the leakage current is collected, the level signal SPD_PE_LeakCurrent_PA0 is output as a voltage value less than 3.3V. The magnitude of the leakage current currently collected can be obtained by converting this voltage value accordingly.

[0111] When the weather forecast information corresponding to the installation area of ​​the surge module 2 is found to have a probability of thunder, the corresponding information is sent through the control terminal and transmitted to the control module 30 through the communication module 34. After receiving the information, the control module 30 is controlled by software to no longer send the level signal SPD_PE_LeakCurProtect_PB6 to the leakage protection unit every preset time (such as 1 hour), and the leakage protection unit keeps closing the 2nd and 3rd ports, or the 6th and 7th ports of the electromagnetic relay RL300. In this way, in thunderous weather, the leakage detection unit does not detect the leakage current, the entrance is in a closed state, and the lightning strike cannot damage the control module 30 and its peripheral circuits.

[0112] In one embodiment, Fig.15 The figure shows a schematic diagram of the structure of the alarm unit. When the control module 30 detects that the leakage current (i.e., equivalent to the second induced current emitted by the leakage current transformer) exceeds the preset threshold value (i.e., greater than 10 mA), the control module 30 will send a corresponding level signal SOUND_ALARM_PC13, and the alarm unit will sound an alarm to remind the operator. The alarm unit mainly includes a transistor Q500 and an active buzzer H500. The base of the transistor Q500 receives the level signal SOUND_ALARM_PC13 issued by the control module 30, triggering the active buzzer H500 to sound to remind the operator. For the specific structure of the alarm unit, see Fig.15 , no further introduction will be given in this embodiment.

[0113] For other structures in the leakage detection unit and the leakage protection unit, refer to Fig.12 and Fig.13 , no further explanation will be given in this embodiment.

[0114] In the use of surge protectors, damage to the grounding wire is very dangerous. In order to detect the loss of grounding in real time, in one embodiment, Fig.16 As shown, the leakage detection module 33 also includes a ground loss detection unit, and the ground loss detection unit includes a third photoelectric coupler U302, the positive electrode of the diode in the third photoelectric coupler U302 is connected to the ground wire, and the negative electrode of the diode in the third photoelectric coupler U302 is respectively connected to the neutral line of the input end of the surge module 2 and the phase voltage line (which can be the first phase voltage line, the second phase voltage line or the third phase voltage line, Fig.16 Taking the first phase voltage line L1 as an example) connected; the emitter of the transistor in the third photoelectric coupler U302 is grounded, and the collector of the transistor in the third photoelectric coupler U3021 is connected to the control module 30.

[0115] Among them, ground loss detection refers to the detection after the ground circuit fails after there is a ground circuit. PE is the ground line, which is low level by default. If the ground is lost, PE will be high level, and it will form the forward excitation voltage of the diode in the third photoelectric coupler U301 with the neutral line, and output the level signal SPD_PE_Lost_PB5 to the corresponding pin on the control module 30 to notify the control module 30 of the occurrence of the ground loss event. Specifically, the ground line PE is generally isolated from the live line and the neutral line. If there is a signal, the third photoelectric coupler will take effect, and the level signal SPD_PE_Lost_PB5 will change from high level to low level. At this time, the control module 30 can find that the ground line PE is abnormal. For other specific structures of the ground loss detection unit, see Fig.16 , no further explanation will be given in this embodiment.

[0116] In one embodiment, Fig.17 As shown, the leakage detection module 33 also includes a decoupling detection unit, which includes a fourth photoelectric coupler U304; the positive electrode of the diode in the fourth photoelectric coupler U304 is connected to the input voltage, the negative electrode of the diode in the fourth photoelectric coupler U304 is connected to the output end of the overcurrent decoupling protection device 26, the emitter of the transistor in the fourth photoelectric coupler U304 is grounded, and the collector of the transistor in the fourth photoelectric coupler U304 is connected to the control module 30.

[0117] Reference Figure 3 , Figure 4 and Fig.17 When the fuse 221 is detached from one end of the impedance unit 25 , the protective spring 22 is used to trigger the trigger switch 260 , so as to inform the control module 30 of the decoupling event of the protective spring 22 through the trigger circuit board 261 .

[0118] As described in Example 2, the overcurrent decoupling protection device 26 includes a trigger switch 260 and a trigger circuit board 261. The output end of the overcurrent decoupling protection device 26 refers to the output interface on the trigger circuit board 261 (i.e., the connection socket L305 connected to J305). This output interface is connected to the fourth photoelectric coupler through J305. Figure 3 and Fig.17When any trigger switch 260 is closed, the 1st and 2nd terminals of J305 are turned on, so that the two ends of the varistor MOV301 are short-circuited, so that the diode in the fourth photocoupler works, and the level signal SPD_UnHook_IN_PA1 is output to the control module 30. In this way, the control module 30 can know whether the surge module 2 has a decoupling event. When a decoupling event is detected, the surge module 2 needs to be replaced in time to prevent the occurrence of dangerous accidents. For other specific structures of the decoupling detection unit, see Fig.17 , no further explanation will be given in this embodiment.

[0119] In one embodiment, Fig.18 and Fig.19 As shown, the communication module 34 includes a coupling transformer T400 and a communication unit U402; the communication pin on the communication unit U402 is connected to the control module 30, the output end PLC_SEND of the communication unit U402 is connected to one end of the secondary side of the coupling transformer T400, and the other end of the secondary side of the coupling transformer T400 is grounded; one end of the primary side of the coupling transformer T400 is respectively connected to alternating currents of different phases, and the other end of the primary side of the coupling transformer T400 is connected to the neutral line.

[0120] The coupling transformer T400 is used to isolate the circuit between the control module 30 and the external device, while allowing signals to be transmitted between the two. The communication unit U402 is the core part of the communication module 34, responsible for converting the status information of the surge protector into a signal that can be transmitted and receiving the control signal from the control terminal, such as Fig.18 As shown, the model of the communication unit U402 may be ES1642-NC, and the model of the coupling transformer T400 may be ES1642-NC-T. The communication pins (including the / RST pin, the PLCRXD pin, and the PLCTXD pin) on the communication unit U402 are connected to the corresponding pins on the control module 30, so that the signal from the control module 30 can be received and converted into a transmittable signal, and the output terminal PLC_SEND of the communication unit U402 interacts with the power line (the first phase voltage line, the second phase voltage line, and the third phase voltage line) through the coupling transformer T400 to communicate through the voltage carrier. For the specific communication method, see the following embodiment.

[0121] In this way, the communication module 34 can transmit the status information of the surge protector (such as whether the protection mechanism is triggered, leakage status, etc.) to the power line in real time to form a whole with other surge protectors. Only one surge protector is needed as a routing device to communicate wirelessly with the control terminal. The control terminal can also remotely control and monitor the surge protector through the communication module 34. This design improves the manageability and reliability of the surge protector. There is no need to lay new communication lines, which simplifies the construction difficulty and realizes real-time update and transmission of signals. For other structures in the communication module 34, refer to Fig.18 and Fig.19 , no further explanation will be given in this embodiment.

[0122] In one embodiment, the control module 30 is of the type STM32F103RC or APM32F103CBT6. Fig. 20 As shown, in this embodiment, APM32F103CBT6 is selected and has a built-in temperature acquisition function, which can collect the temperature of the surge protector in real time. The specific structure and working mode of the control module 30 are not described in detail in this embodiment. In one embodiment, the monitoring circuit also includes other modules, such as a wireless communication module, etc. The control module 30 also receives other signals (such as memory signals and wireless communication signals, etc.), which are not described in detail in this embodiment. For the chip APM32F103CBT6, please refer to its instruction manual, which is not described in detail in this embodiment.

[0123] In one embodiment, Fig.21 and Fig. 22 As shown, the monitoring circuit also includes a power module 35, and the power module 35 includes a voltage conversion unit U100. The voltage conversion unit U100 is used to convert an AC signal into a DC signal. The model of the voltage conversion unit U100 can be PLG05A. The voltage conversion unit U100 is used to receive 220V AC power and convert the 220V AC power into 12V DC power. The 12V DC power is transmitted through Fig. 22 The circuit shown in the figure obtains a 3.3V voltage. The 3.3V input voltage used by all modules in this embodiment is output by the power module 35 (in all figures, the places marked with 3V3 are input with the 3.3V voltage). Fig.21 and Fig. 22 , no further explanation will be given in this embodiment.

[0124] This embodiment proposes a monitoring circuit for a surge protector, monitors the status of the surge module 2 through an overcurrent detection module 31, an overvoltage detection module 32 and a leakage detection module 33, and transmits the monitoring result to the control module 30. The control module 30 then outputs corresponding data to the communication module 34 to communicate with the control terminal, thereby realizing real-time monitoring of the status of the surge module 2, reducing the size of the surge protector, saving costs, and facilitating installation.

[0125] Embodiment 4:

[0126] Based on the surge module 2 of embodiment 2 and the monitoring circuit for the surge protector of embodiment 3, a surge protector is proposed in this embodiment, such as Fig.23 and Fig.24 As shown, it comprises: a protective housing 1, a surge module 2 and an intelligent module 3, wherein the intelligent module 3 comprises a monitoring circuit and a circuit board for a surge protector as described in Example 2, and the monitoring circuit for a surge protector is arranged on the circuit board; the surge module 2 is electrically connected to the intelligent module 3; the input end of the surge module 2 is used to connect to input alternating current of different phases on the electronic device, and the surge module 2 and the intelligent module 3 are both arranged in the protective housing 1; the surge module 2 comprises an overcurrent transformer 20 and a leakage current transformer sensor 21; the overcurrent transformer 20 and the leakage current transformer 21 are respectively connected to the intelligent module 3. When the surge module 2 has an overcurrent, the overcurrent transformer 20 is used to generate a first induced current, and transmit the first induced current to the intelligent module 3, so as to monitor whether the surge module 2 has an overcurrent; when the surge module 2 has a leakage, the leakage current transformer 21 is used to generate a second induced current, and transmit the second induced current to the intelligent module 3, so as to monitor whether the leakage current of the surge module 2 is within a preset range.

[0127] Wherein, referring to Embodiment 2 and Embodiment 3, the electrical connection between the intelligent module 3 and the surge module 2 refers to that the overcurrent detection module 31 in the intelligent module 3 is connected to the overcurrent transformer 20 in the surge module 2, the leakage detection module 33 in the intelligent module 3 is connected to the leakage current transformer 21 in the surge module 2, and the overvoltage detection module 32 in the intelligent module 3 is connected to the voltage input terminal in the surge module 2. The connection method can be welding or plugging, etc., which is not specifically limited in this embodiment. The circuit board can be a printed circuit board (PCB).

[0128] like Fig.25 and Fig.26As shown, the protective shell 1 adopts an upper and lower opening and closing structure, and is easy to assemble; the interior of the protective shell 1 includes two compartments, wherein the left compartment is used to place the surge module 2, and the right compartment is used to place the intelligent module 3. The surge module 2 and the intelligent module 3 are integrated into one device, and national standard structural parts are adopted, such as an M6 wiring frame connected to the protective spring clip 22 and the incoming terminal 23.

[0129] In one embodiment, referring to Fig.26 The protective housing 1 is also provided with insulating partitions 10 and fixed positions 11 arranged in phase, the surge module 2 is arranged between the insulating partitions 10, and the incoming terminal 23 is arranged in the fixed position 11, and the overall structural layout is reasonable. The protective housing 1 is made of insulating flame-retardant material, which is sturdy and durable. QR code information can be pasted on the outside of the protective housing 1 to facilitate software scanning to obtain relevant equipment parameters.

[0130] The surface of the protective shell 1 has clear marking information, including information such as working power supply, grounding alarm, failure alarm lamp hole and external wiring position. The protective shell 1 adopts a universal design and can be applied to a variety of different models. The models are distinguished by a self-adhesive identification plate on the outside. The bottom of the protective shell 1 adopts a standard guide rail fixing method, which is easy to install on site.

[0131] In one embodiment, Fig.24 As shown, a metal shielding cover is also provided in the right compartment, and the smart module 3 is arranged in the metal shielding cover to shield the interference of external electromagnetic signals on the smart module 3. The specific structure and working principle of the surge module 2 and the smart module 3 refer to the above-mentioned embodiment 2 and embodiment 3, which will not be repeated in this embodiment.

[0132] In one embodiment, when the surge module 2 is struck by lightning, the overcurrent transformer 20 generates a first induced current, and the intelligent module 3 generates a corresponding signal according to the first induced current and transmits it to the control terminal to monitor whether the surge protector is overcurrent. The leakage current transformer 21 generates a second induced current, and the intelligent module 3 generates a corresponding signal according to the second induced current and transmits it to the control terminal to monitor whether the surge protector is leaking current.

[0133] In this embodiment, the surge protector is designed as an integrated structure, and the surge module 2 and the intelligent module 3 are integrated in a protective housing 1. The intelligent module 3 can automatically detect leakage current and lightning strikes, and determine whether the lightning protection function of the surge protector fails or deteriorates. The device status can be uploaded in real time to facilitate timely replacement, ensuring that important electronic equipment is protected at all times; using power lines as communication channels, it is suitable for any scenario. The integrated design greatly improves the reliability and ease of use of the surge protector, and the installation method is the same as that of conventional surge protectors, and the installation is simple and fast.

[0134] Embodiment 5:

[0135] In Example 1, a split-type intelligent surge protection architecture is proposed. Based on the surge protector proposed in Example 4, an integrated intelligent surge protection architecture is proposed in this embodiment. Fig.23 and Fig. 27 As shown, it includes multiple backup protection modules 4, surge protectors and data acquisition modules 5; one end of the backup protection module 4 is respectively connected to the voltage lines of different phases at the input end of the electronic device, and the other end of the backup protection module 4 is respectively connected to the voltage input end on the surge protector; the communication interface on the data acquisition module 5 is connected to the communication interface on the surge protector ( Fig. 20 The surge protector is used to generate a corresponding electrical signal when struck by lightning, and transmit the corresponding electrical signal to the data acquisition module 5, and the data acquisition module 5 is used to generate corresponding data information according to the corresponding electrical signal, and transmit the corresponding data information to the control terminal.

[0136] Among them, in one embodiment, the integrated intelligent surge architecture includes four backup protection modules 4, and the function of the backup protection module 4 is to provide additional protection when the surge protector fails or fails to work properly. The surge protector is used to detect and suppress surge events in electronic equipment. When the surge protector is struck by lightning, it will generate electrical signals, which reflect the characteristics of the surge. The surge protector transmits the generated electrical signals to the data acquisition module 5 for further processing and analysis. The data acquisition module 5 is responsible for collecting the electrical signals transmitted by the surge protector and converting them into data information. The data information reflects the intensity, duration and other parameters of the surge. The data acquisition module 5 transmits the generated data information to the control terminal, such as a monitoring system or a control center, for real-time monitoring and analysis.

[0137] The surge protector proposed in Example 4 includes an intelligent module 3, and the intelligent module 3 includes a communication module 34. The communication module 34 can directly transmit the information obtained by the control module 30 through the power line (first phase voltage line, second phase voltage line and third phase voltage line) through power line communication (Power line Communication, abbreviated as PLC), that is, carrier communication; in this embodiment, the communication function is realized by the data acquisition module 5, and the data acquisition module 5 can communicate with the intelligent module in the surge protector through RS485 communication. The data acquisition module 5 is also connected to the antenna, and the information obtained from the intelligent module is processed accordingly and transmitted to the control terminal by wireless means.

[0138] Since PLC communication is too sensitive to interference, and there are often various electrical equipment on low-voltage power lines, which will cause different noise and impedance effects on the power lines, and in order to ensure the transmission quality, PLC will not pursue long-distance transmission. Therefore, the wireless communication of the data acquisition module 5 in this embodiment can be applied to lightning protection projects in more remote areas, that is, each surge protector can communicate with the control terminal through wireless communication, which is more convenient for signal transmission.

[0139] The specific structures and working principles of the surge module 2 and the smart module 3 refer to the above embodiments, which will not be described in detail in this embodiment.

[0140] In this embodiment, a data acquisition module 5 is connected to the surge protector, and the information collected by the surge protector is obtained through the data acquisition module 5, and the information collected by the surge protector is transmitted to the control terminal through wireless transmission. At the same time, the control terminal can also send commands to the data acquisition module 5 through wireless transmission, and then the corresponding commands are transmitted to the surge protector through the data acquisition module 5. The PLC communication is replaced by wireless communication, so that the signal transmission is more stable. In addition, this embodiment is also suitable for lightning protection projects in remote areas.

[0141] Embodiment 6:

[0142] In Example 5, an integrated intelligent surge protection architecture is proposed. In this embodiment, a surge protection system in a low-voltage power distribution system is proposed, such as Fig.28 As shown, it includes: a main distribution room 7, at least one distribution branch 8 and a surge protector; the distribution branch 8 is connected to the main distribution room 7, and a distribution box is arranged on the distribution branch 8; the voltage input ends of the main distribution room 7 and the distribution box are both connected to the surge protector; the distribution box is arranged on each floor to distribute power to the electrical equipment on each floor respectively.

[0143] Among them, since the design is for a surge protection system for buildings such as buildings, the installation location of the surge protector will not be too remote. Therefore, this embodiment can adopt the surge protector proposed in Example 4, and can transmit the corresponding signal to the power line through PLC carrier communication, and then any surge protector can transmit the corresponding signal to the control terminal, which will be specifically introduced in the following embodiments.

[0144] The main distribution room 7 is the center of the entire low-voltage power distribution system. It is connected to the high-voltage power grid and receives power from it. The main distribution room 7 is responsible for distributing power to different distribution boxes. The distribution branch 8 starts from the main distribution room 7 and transmits power to each distribution box. Each branch may serve the electrical equipment on one or more floors. The distribution box is usually set up on each floor to distribute power to the electrical equipment on that floor. The distribution box can be a simple switch cabinet or a more complex automated distribution system. Since there will be different power demands in a building, the types and quantities of distribution boxes will be different. The surge protector is installed at the voltage input end of the main distribution room 7 and the distribution box to detect and suppress surges. At the same time, the surge protector is connected to the voltage input end of the main distribution room 7 and the distribution box to protect the entire distribution system from the impact of surges. When a surge occurs in the power grid, the surge protector will act quickly to direct the excess voltage to the ground, thereby protecting the electrical equipment from damage. It is worth noting that during installation, a backup protection module 4 will be connected to the front end of the surge protector. For more details, refer to Example 1 or Example 5. The surge protectors proposed in these two embodiments are applicable to this embodiment.

[0145] In this way, the surge protection system provides an effective protection layer for the low-voltage power distribution system, ensuring the safe and stable operation of electrical equipment. When designing and implementing a surge protection system, factors such as the selection of surge protectors, installation location, rated voltage, and response time need to be considered to ensure the best protection effect.

[0146] Next, several examples of distribution branches 8 are listed for illustration.

[0147] In one embodiment, taking the lighting branch as an example, referring to Fig.29 When the distribution branch 8 is a lighting branch, the distribution branch 8 also includes a main lighting distribution box, the voltage input end of which is connected to the surge protector; the main lighting distribution box is connected to different distribution boxes AL on each floor to distribute power to different distribution boxes. It is necessary to explain that Fig.29In the figure, AP represents the power distribution box; AL represents the lighting distribution box; ZAL represents the main lighting distribution box; ALE represents the emergency lighting distribution box; AT represents the dual power switching box; AW represents the meter box; EPS represents the fire emergency power supply, KAP represents the air conditioning power distribution box, and DT represents the elevator distribution box. The numbers following the English letters are only used for identification and have no other special meanings. SPD1, SPD2 and SPD3 all represent surge protectors, which will not be repeated in the following embodiments.

[0148] Among them, the lighting branch is mainly used for lighting, and the lighting branch includes a main lighting distribution box. In order to facilitate the supply of power upward, the main lighting distribution box can be set on the first floor, and multiple distribution boxes AL are connected to the main lighting distribution box on each floor. For example: AL101, AL102 and AL103 are set on the first floor, and AL201, AL202 and AL203 are set on the second floor until the lighting needs of each floor are met. Surge protectors are connected to all distribution boxes in the entire building. For the specific structure and working principle of the surge protector, please refer to Example 4, and no further explanation is given in this embodiment. It is worth noting that all surge protectors are integrated with a communication module 34, and the surge protectors are automatically networked and communicated using the PLC power carrier method. The RS485 serial port is used for external data transmission. Only any one of the surge protectors is needed as a routing device, and a wireless transceiver device (i.e., the data acquisition module 5 in Example 5 or the communication module 6 in Example 1) is connected to this surge protector. The wireless transceiver device can be a data transfer unit (Data Transfer Unit, abbreviated as: DTU), etc., so that all surge protectors can exchange data with the cloud server and monitor the status of all surge protectors in real time.

[0149] In one embodiment, continue to refer to Fig.29 When the distribution branch 8 is an elevator branch, the distribution box is set on the top floor of the building, and the number of the distribution boxes matches the number of elevators. The elevator power supply is special, and only a distribution box (such as DT401, DT402 and DT403, etc.) needs to be set up on the top floor for each elevator, and a surge protector is connected to each distribution box to protect the distribution box.

[0150] In one embodiment, Fig.29 As shown, the power distribution branch 8 in a building also includes an emergency lighting branch, a fire load branch, an air conditioning load branch, a refrigeration distribution branch, and a process load distribution branch, etc. The specific details are not described in detail in this embodiment.

[0151] This embodiment connects a surge protector to all distribution boxes in the low-voltage power distribution system, and protects each distribution box from lightning through the surge protector. The embodiment can be applicable to the low-voltage power distribution system of any building or structure, and can well protect electronic equipment in the building or other structure from lightning strikes, thereby protecting all electronic equipment in the building from damage by lightning strikes and minimizing the risk of lightning strikes to the power supply system.

[0152] Embodiment 7:

[0153] In Example 6, a surge protection system in a low-voltage power distribution system is proposed. In this embodiment, an intelligent lightning protection monitoring system is proposed. Fig.30 As shown, it includes a power distribution main control room 9, at least one surge protection system in a low-voltage power distribution system as described in Example 6, and at least one data collector. The power distribution main control room 9 is provided with a control terminal, the control terminal is used to connect to a cloud server, and the data collector is connected to the cloud server; the surge protection system in the low-voltage power distribution system includes a plurality of surge protectors, all of which are connected to a main power supply AC line, and the data collector is connected to the AC power in the surge protection system in the low-voltage power distribution system; the data collector is used to collect the status of all surge protectors to obtain collection results, and upload the collection results to the control terminal through the cloud server.

[0154] Among them, the power distribution control room 9 is the central control center of the entire intelligent lightning protection detection system, which is equipped with a control terminal, which is used to connect to the cloud server and can exchange data and remotely control through the Internet. The control terminal can be a smart phone and a smart computer. The surge protection system in the low-voltage power distribution system is a protection device installed in the low-voltage power distribution system of a building or a building, which is used to prevent surges from damaging electronic equipment. For the specific structure of the surge protection system in the low-voltage power distribution system, see Example 6.

[0155] It is worth noting that, in order to distinguish and facilitate description, the data collector proposed in this embodiment and the data acquisition module 5 proposed in Example 5 can be the same device. The data collector in this embodiment is a data collection device of the system, which is used to collect the status information of the surge protector. Specifically, the structure of the surge protector described in Example 4 and Example 6 have been described. The surge protectors use a carrier mode to automatically network and communicate, and the RS485 serial port is used for external data transmission. Only any one of the surge protectors is needed as a routing device, and an external wireless transceiver device (such as DTU) is connected to realize data exchange between all devices and the cloud server, and the status of the surge protector is monitored in real time. Specifically, each surge protector has a unique device address. The system is connected to one of the surge protectors as a routing device through DTU, and accesses other surge protectors through the corresponding address; each surge protector device itself has an independent QR code, which is scanned by a mobile phone APP to set the parameter information of the surge protector and synchronize it to the system, including location information, so that when the surge protector is put into operation, the device will be quickly located.

[0156] Therefore, in one embodiment, it is only necessary to connect the data collector to any surge protector in the surge protection system in the entire low-voltage power distribution system to obtain the status of all surge protectors. The data collector uploads the collected surge protector status information to the cloud server, and then transmits it to the control terminal through the cloud server. Through this design, the intelligent lightning protection monitoring system can monitor the status of the surge protector in real time, and issue an alarm or take automatic protection measures when necessary. In addition, through the integration of the cloud server, the system can realize remote monitoring and data analysis, which improves the intelligence and reliability of the lightning protection system. At the same time, the control terminal can set historical data query functions, fault point location, fault alarm and intelligent inspection functions, which will not be described in detail in this embodiment.

[0157] The specific structure and working principle of the surge protector refer to the above-mentioned embodiment 4, which will not be repeated in this embodiment.

[0158] Embodiment 8:

[0159] In Example 4, a surge protector is proposed. In this embodiment, an intelligent lightning protection online monitoring method is proposed. Fig.31 As shown, and referring to the drawings proposed in Example 2 and Example 3, the smart lightning protection online monitoring method includes:

[0160] Step 101: When the surge module 2 is struck by lightning, the overcurrent transformer 20 generates a first induced current, and the intelligent module 3 generates a corresponding signal according to the first induced current and transmits it to the control terminal to monitor whether the surge protector is overcurrent.

[0161] Referring to the structure of the intelligent module 3 described in Example 3, the rectifier unit U200 in the intelligent module 3 converts the first induced current into a DC signal; the surge suppressor D200 clamps the voltage of the DC signal below a preset value; the first photocoupler U201 outputs a first high-level signal to the control module 30 according to the DC signal, so as to trigger the control module 30 to obtain an overcurrent event occurring in the surge module 2.

[0162] For the specific structure and implementation principle of the overcurrent detection module 31 , please refer to Example 3.

[0163] Step 102: The intelligent module 3 obtains the voltage of the voltage input terminal of the surge module 2, and generates a corresponding signal to transmit to the control terminal to monitor whether the surge protector is over-voltage.

[0164] When an overvoltage occurs in the voltage of any phase, the second photoelectric coupler (U202, U203 or U204) outputs a second high level signal to the control module 30 to trigger the control module 30 to obtain an overvoltage event.

[0165] For the specific structure of the overvoltage detection module 32 , please refer to Example 3.

[0166] Step 103: the leakage current transformer 21 generates a second induced current, and the intelligent module 3 generates a corresponding signal according to the second induced current and transmits it to the control terminal to monitor the magnitude of the leakage current on the surge protector.

[0167] The control module 30 is used to send a leakage protection trigger signal to the leakage protection unit after a preset interval, and open the detection channel of the leakage current transformer 21 through the electromagnetic relay RL300, so that the leakage detection unit detects the leakage current on the surge module 2; the first operational amplifier U300A is used to receive the second induced current and amplify the second induced current, and the second operational amplifier U300B further amplifies the second induced current and outputs a third high-level signal to the control module 30 to trigger the control module 30 to obtain the leakage current size on the surge module 2.

[0168] During normal operation, the leakage current on the surge protector is generally less than or equal to 0.5μA. If the leakage current is detected to be greater than 10mA, it is judged that the performance of the surge protector has decreased and deteriorated. When the leakage current is greater than 20mA, it is judged to be a failure and a new surge protector needs to be replaced.

[0169] The specific structure and working principle of the leakage detection module 33 refer to Example 3.

[0170] Step 104: the intelligent module obtains the status of the protective spring 22 on the surge module 2, and generates a corresponding signal to transmit to the control terminal to monitor whether the surge protector is unhooked.

[0171] When the fuse 221 in the surge module 2 is detached from one end of the impedance unit 25 , the trigger switch 260 is triggered by the protective spring 22 , so as to inform the control module 30 of the decoupling event of the protective spring 22 through the trigger circuit board 261 .

[0172] For the specific structure and working principle of the decoupling detection unit, please refer to Example 3.

[0173] The specific structure of the surge protection module is described in detail in Example 2, Example 3 and Example 4, and will not be described in detail in this example.

[0174] This embodiment monitors the status of the surge module 2 through the intelligent module 3. The intelligent module 3 can automatically detect leakage current and lightning strikes, determine whether the lightning protection function of the surge protector fails or deteriorates, and can upload the device status in real time to facilitate timely replacement, thereby ensuring that important electronic equipment is protected at all times.

[0175] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
