Description

Technical Field

[0001] The present invention relates to the technical field of busbars, and in particular to an intelligent sensing multi-stage regulating protection type busbar and a protection method thereof. Background Art

[0002] In the power system, busbar is a conductive device used to connect different electrical equipment, such as generators, transformers, switchgear, etc. It is a large conductive rod or wire, usually made of copper or aluminum, used to transmit electrical energy. The main function of the busbar is to transfer electrical energy between different electrical equipment and provide a shared electric field and voltage level. The busbar functions include collecting, distributing and transmitting electrical energy. The busbar has various shapes and structures, and can be roughly divided into three categories: hard busbar, soft busbar and closed busbar.

[0003] The prior art has the following deficiencies:

[0004] When the busbar is used in an underground humid environment, staff will regularly inspect the busbar to check whether the various components of the busbar are damaged. However, in actual applications, due to the existence of uncertain factors that may cause damage to various components of the busbar (such as damage by rats and ants or corrosion damage, etc.), if the busbar terminal is flooded and is not in the inspection period, the busbar abnormality may cause the busbar to short-circuit, thereby causing damage to the electrical equipment connected to the busbar;

[0005] Based on this, the present invention proposes an intelligent sensing multi-level adjustment protection type bus and a protection method thereof, which can intelligently sense the abnormalities existing in the bus, thereby predicting bus failures and taking timely measures to solve the above-mentioned problems. Summary of the invention

[0006] The purpose of the present invention is to provide an intelligent sensing multi-stage adjustment protection type busbar and a protection method thereof, so as to solve the deficiencies in the background technology.

[0007] In order to achieve the above object, the present invention provides the following technical solution: a protection method for an intelligent sensing multi-stage regulating protection busbar, the protection method comprising the following steps:

[0008] S1: When the bus is supplying power to multiple devices, the bus controller obtains the operating status of multiple devices in real time through the control systems of the multiple devices;

[0009] S2: When a device is in an abnormal operating state, the busbar controller controls the electromagnetic coil corresponding to the device cable to be energized. After the electromagnetic coil is energized, it generates the same magnetic pole as the corresponding permanent magnet, and the permanent magnet pushes the conductive rod out of the insulating plug to separate the conductive rod from the plug. After disconnecting the current between the busbar and the abnormal operating state device, a warning signal is sent to the staff to prompt;

[0010] S3: The busbar controller obtains multiple data of the busbar through multiple sensors, analyzes the multiple data based on the abnormal protection model, and predicts the future usage status of the busbar;

[0011] S4: Generate warnings to staff and perform corresponding power outage control based on the prediction results;

[0012] S5: When the abnormal operation state of the equipment returns to normal or the abnormal use state of the bus returns to normal, the bus controller automatically disconnects the power supply of the corresponding electromagnetic coil. After the permanent magnet is no longer under force, the reset spring pushes the conductive rod into the insulating plug and contacts the plug, so that the conductive bar continues to supply power to the equipment.

[0013] In a preferred embodiment, in step S3, establishing the abnormality protection model includes the following steps:

[0014] S31: After standardizing the humidity value of the cavity area between the waterproof cover and the insulating cover, the vibration amplitude of the waterproof cover, the harmonic anomaly index of the conductive bar, and the resistance impedance of the insulating cover, the busbar anomaly index my is calculated and obtained. The calculation expression is:

[0015] Wherein, ZDS is the vibration amplitude of the waterproof cover, XBY is the harmonic anomaly index of the conductive bar, ZKD is the resistance impedance of the insulating cover, SDK is the humidity value of the cavity area between the waterproof cover and the insulating cover, ω1, ω2, ω3, ω4 are the proportional coefficients of the vibration amplitude of the waterproof cover, the harmonic anomaly index of the conductive bar, the resistance impedance of the insulating cover, and the humidity value of the cavity area between the waterproof cover and the insulating cover, and ω1, ω2, ω3, ω4 are all greater than 0;

[0016] S32: Compare the calculated bus abnormality index my value with the preset abnormality threshold A and abnormality threshold B to complete the establishment of the abnormality protection model, wherein the abnormality threshold A is less than the abnormality threshold B, the abnormality threshold A is used to determine whether there is an abnormality in the bus, and the abnormality threshold B is used to determine the severity of the bus abnormality.

[0017] In a preferred embodiment, in step S3, the bus controller obtains multiple data of the bus through multiple sensors, and after analyzing the multiple data based on the abnormal protection model, predicting the future use state of the bus includes the following steps:

[0018] S33: The busbar controller periodically obtains the humidity value of the cavity area between the waterproof cover and the insulating cover, the vibration amplitude of the waterproof cover, the harmonic abnormality index of the conductive bar, and the resistance impedance of the insulating cover;

[0019] S34: Substitute the humidity value of the cavity area between the waterproof cover and the insulating cover, the vibration amplitude of the waterproof cover, the harmonic anomaly index of the conductive bar, and the resistance impedance of the insulating cover into the calculation formula of the busbar anomaly index my in the abnormal protection model to calculate the busbar anomaly index my value;

[0020] S35: If the bus abnormality index my value is ≤ the abnormality threshold A, it is analyzed that there is no abnormality in the bus, and it is predicted that the bus will be in normal use in the future;

[0021] S36: If the abnormal threshold value A is less than the bus abnormal index my value ≤ the abnormal threshold value B, the bus is analyzed to have a slight abnormality, and the bus is predicted to be in a first-level abnormal usage state in the future;

[0022] S37: If the bus abnormality index my value is greater than the abnormality threshold B, it is analyzed that the bus has a severe abnormality, and the bus is predicted to be in a secondary abnormal usage state in the future.

[0023] In a preferred embodiment, in step S4, generating an early warning to the staff and performing corresponding power-off control according to the prediction result includes the following steps:

[0024] S41: When the busbar is analyzed to have no abnormality and the busbar is predicted to be in normal use in the future, the busbar controller does not perform control;

[0025] S42: When the bus is analyzed to have a slight abnormality and it is predicted that the bus will be in a first-level abnormal use state in the future, the bus controller sends a warning signal to the staff. After the staff controls the equipment connected to the bus to shut down, the bus controller controls all the electromagnetic coils to be connected to the power supply at the same time. After the electromagnetic coils are energized, they generate the same magnetic poles as the corresponding permanent magnets. The permanent magnets push the conductive rod out of the insulating plug, so that the conductive rod is separated from the plug, and the current between the equipment and the bus is disconnected;

[0026] S43: When the bus is analyzed to have a serious abnormality and it is predicted that the bus will be in a secondary abnormal usage state in the future, the bus controller directly controls all the electromagnetic coils to connect to the power supply at the same time. After the electromagnetic coils are energized, they generate the same magnetic poles as the corresponding permanent magnets. The permanent magnets push the conductive rod out of the insulating plug, separating the conductive rod from the plug, disconnecting the current between the equipment and the bus, and then sending a warning signal to the staff.

[0027] In a preferred embodiment, step S4 further comprises the following steps:

[0028] S44: Obtain the bus abnormality index my of all buses in the first-level abnormal usage state during the historical operation of the bus, and calculate the standard deviation of the bus abnormality index and the average value of the bus abnormality index;

[0029] S45: Calculate the abnormal threshold C by using the abnormal threshold A and the abnormal threshold B, where the abnormal threshold C= / 2, and the abnormal threshold C is used to determine whether the average value of the bus abnormal index of the first-level abnormal usage state is biased toward the abnormal threshold A or the abnormal threshold B;

[0030] S46: If the average value of the bus abnormality index is ≤ the abnormality threshold C, and the standard deviation of the bus abnormality index is ≤ the standard deviation threshold, and the analysis shows that the bus in the first-level abnormal usage state is rapidly developing towards a normal trend, then the bus controller controls all electromagnetic coils to operate after T time;

[0031] S47: If the average value of the bus abnormality index is ≤ the abnormality threshold C, and the standard deviation of the bus abnormality index is greater than the standard deviation threshold, and the analysis shows that the bus in the first-level abnormal usage state is slowly developing towards a normal trend, then the bus controller controls all electromagnetic coils to operate after T / 1.1 time;

[0032] S48: If the average value of the bus abnormality index is greater than the abnormality threshold C, and the standard deviation of the bus abnormality index is greater than the standard deviation threshold, it is analyzed that the bus in the first-level abnormal usage state is slowly developing towards the second-level abnormal trend, then the bus controller controls all electromagnetic coils to operate after T / 1.3 time;

[0033] S49: If the average value of the bus abnormality index is greater than the abnormality threshold C, and the standard deviation of the bus abnormality index is less than or equal to the standard deviation threshold, and the analysis shows that the bus in the first-level abnormal usage status is rapidly developing towards the second-level abnormal trend, the bus controller controls all electromagnetic coils to operate after T / 1.5 time.

[0034] In a preferred embodiment, the calculation expression of the busbar abnormality index standard deviation MQ is: The average value of the abnormal index of the main line my avg The calculation expression is: Where i = {1, 2, 3, ..., n}, n represents the number of bus abnormality indexes of all buses in the first-level abnormal usage state during the historical operation of the bus, n is a positive integer, my i Indicates the abnormal index value of the ith busbar, my avg Represents the average value of the bus anomaly index.

[0035] In a preferred embodiment, in step S2, when a certain device is in an abnormal operating state, the bus controller controls the electromagnetic coil corresponding to the device cable to be energized, including the following steps:

[0036] S21: After the cable of the equipment is inserted into the insulating sleeve, the staff inputs the equipment number information into the busbar controller. Each equipment number includes equipment information and the number of the connected insulating sleeve;

[0037] S22: When a device is abnormal, the busbar controller finds the electromagnetic coil at the insulating sleeve corresponding to the abnormal device based on the device code information, and energizes the electromagnetic coil, so that the electromagnetic coil pushes the conductive rod out of the insulating plug through the permanent magnet, so that the conductive rod is separated from the plug.

[0038] In a preferred embodiment, in step S3, the bus controller acquires multiple bus data through multiple sensors, including the following steps:

[0039] The vibration amplitude of the waterproof cover is obtained by the vibration sensor set on the waterproof cover, and the calculation expression of the harmonic anomaly index of the conductive bar is: In the formula, I j represents the current amplitude of the j-th order harmonic, I1 represents the amplitude of the fundamental current, m represents the harmonic order obtained in the conductive bar, the insulation cover resistance impedance is obtained by a ground resistance tester, and the humidity value of the cavity area between the waterproof cover and the insulation cover is obtained by a humidity sensor arranged on the side of the insulation cover close to the waterproof cover.

[0040] The present invention also provides an intelligent sensing multi-stage regulating protective busbar, comprising an insulating cover and a conductive bar detachably arranged inside the insulating cover, a plurality of insulating plugs are fixedly arranged on one side of the insulating cover, and the characteristics are: a reset power connection mechanism is arranged between the insulating plug and the conductive bar, and the number of the reset power connection mechanisms is equal to the number of the insulating plugs;

[0041] The reset power connection mechanism includes a conductive rod and a reset spring, and one end of the conductive rod is plugged into the insulating plug, and the other end of the conductive rod is slidably embedded in the conductive bar, and the reset spring is embedded in the conductive bar, and one end of the reset spring abuts against the conductive rod, so that the conductive rod is kept inserted into the insulating plug under normal conditions;

[0042] An electromagnetic coil is fixedly provided on the outer side of one end of the insulating plug close to the conductive row, and a permanent magnet corresponding to the position of the electromagnetic coil is fixedly provided on one end of the conductive rod close to the insulating plug. When an abnormality is detected in the busbar, the electromagnetic coil is connected to a power supply to generate the same magnetic pole as the permanent magnet, and the conductive rod is pushed out of the insulating plug through the permanent magnet.

[0043] In a preferred embodiment, a water-blocking plate is provided inside the insulating plug, a rewinding spring is provided at the top of the water-blocking plate, and the top of the water-blocking plate is movably connected to the insulating plug through the rewinding spring. When the conductive rod moves out of the insulating plug, the rewinding spring pushes the water-blocking plate to rotate counterclockwise, so that the water-blocking plate is rotated out of the groove at the top of the inner wall of the insulating plug. When the water-blocking plate rotates counterclockwise, the bottom end of the water-blocking plate is embedded in the limiting groove at the bottom of the inner wall of the insulating plug.

[0044] In the above technical solution, the technical effects and advantages provided by the present invention are:

[0045] 1. The present invention uses a bus controller to obtain the operating status of multiple devices in real time through the control systems of multiple devices. When the operating status of a certain device is abnormal, the bus controller controls the electromagnetic coil corresponding to the cable of the device to be energized. After the electromagnetic coil is energized, it generates the same magnetic pole as the corresponding permanent magnet, and pushes the conductive rod out of the insulating plug through the permanent magnet to separate the conductive rod from the plug. After disconnecting the current between the bus and the abnormal operating status equipment, a warning signal is sent to the staff to prompt. The bus controller obtains multiple data of the bus through multiple sensors, analyzes multiple data based on the abnormal protection model, predicts the future use status of the bus, and generates an early warning to the staff and performs corresponding power-off control based on the prediction results. This protection method can not only perform multi-level segmented control according to the equipment status, but also perform comprehensive control in combination with the bus status itself, effectively improving the safety of bus use;

[0046] 2. The present invention uses an abnormal protection model to comprehensively standardize the humidity value of the cavity area between the waterproof cover and the insulating cover, the vibration amplitude of the waterproof cover, the harmonic abnormal index of the conductive bar, and the resistance impedance of the insulating cover, and then calculates and obtains the bus abnormality index, which effectively improves the data processing efficiency and can predict the future use status of the bus. Compared with the existing method of detecting faults and giving warnings, the present invention predicts the future use status of the bus, can give early warning and control before the bus fails, and further ensures the safety of the bus use;

[0047] 3. The present invention predicts the future use status of the busbar, so that it can send an early warning signal to the staff before the busbar fails, so that the staff can shut down the equipment in advance to avoid sudden disconnection of the current between the busbar and the equipment, causing the equipment to stop (which can easily cause damage to the equipment).

[0059] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0060] Example 1: Please refer to Figure 1 and Figure 4 As shown, the protection method of an intelligent sensing multi-stage regulating protection busbar described in this embodiment includes the following steps:

[0061] The insulating cover 1 is fixedly mounted on the busbar bridge, and the conductive bar 2 is connected to the main power supply through the socket 201. After the plug 501 of the cable 5 is inserted into the insulating plug 3, the cable 5 is energized with the conductive bar 2 through the conductive rod 401. When the busbar supplies power to multiple devices, the busbar controller obtains the operating status of multiple devices in real time through the control systems of the multiple devices, including the following steps:

[0062] Determine the communication protocol to ensure that the bus controller and the control systems of each device can correctly exchange information. Common communication protocols include Modbus, DNP3, IEC61850, etc. Establish a network connection to ensure data communication between the bus controller and each device, which may involve Ethernet, serial communication, etc. The bus controller needs to be able to identify and address each connected device to ensure correct communication with it. Each device should have a unique identifier in the system. Through the communication protocol, the bus controller sends data collection requests to each device to obtain the real-time operating data of each device, such as current, voltage, temperature, etc. The bus controller analyzes the data collected from each device to monitor the status of the device, which may include the operating status, health status, fault alarm, etc. of the device;

[0063] When a device fails, the bus controller can receive the corresponding fault alarm and perform diagnosis, which can help operation and maintenance personnel quickly locate and solve the problem. The bus controller may have a remote control function and can send control instructions to each device through the communication protocol, such as starting, stopping, adjusting parameters, etc. The collected data can be stored by the bus controller and historical data analysis can be performed, which helps to understand the trend of equipment operation, discover potential problems in advance, and optimize system performance. Ensure the security of the communication process, adopt appropriate encryption and identity authentication mechanisms, and authority control to ensure that only authorized users or systems can access and modify device information.

[0064] like Figure 6 As shown, when a certain device is in an abnormal operating state, the busbar controller controls the electromagnetic coil 301 corresponding to the cable 5 of the device to be energized. After the electromagnetic coil 301 is energized, it generates the same magnetic pole as the corresponding permanent magnet 4011, and pushes the conductive rod 401 out of the insulating plug 3 through the permanent magnet 4011, so that the conductive rod 401 is separated from the plug 501, and the current between the busbar and the abnormal operating state device is disconnected, and then a warning signal is sent to the staff for prompting. The busbar controller obtains multiple data of the busbar through multiple sensors, and after analyzing multiple data based on the abnormal protection model, predicts the future use state of the busbar, and generates an early warning to the staff and performs corresponding power-off control according to the prediction results. When the abnormal operating state device returns to normal or the abnormal use state of the busbar returns to normal, the busbar controller automatically disconnects the power supply of the corresponding electromagnetic coil 301. After the permanent magnet 4011 is not subjected to force, the reset spring 404 pushes the conductive rod 401 to insert into the insulating plug 3 and contact with the plug 501, so that the conductive bar 2 continues to supply power to the device;

[0065] After the cable 5 of the equipment is inserted into the insulating sleeve 3, the staff inputs the equipment number information into the bus controller. Each equipment number includes equipment information and the number of the connected insulating sleeve 3. When a certain equipment is abnormal, the bus controller finds the electromagnetic coil 301 at the insulating sleeve 3 corresponding to the abnormal equipment based on the equipment number information, and energizes the electromagnetic coil 301, so that the electromagnetic coil 301 pushes the conductive rod 401 out of the insulating plug 3 through the permanent magnet 4011, so that the conductive rod 401 is separated from the plug 501, thereby achieving precise control.

[0066] The present application uses a bus controller to obtain the operating status of multiple devices in real time through the control systems of multiple devices. When the operating status of a certain device is abnormal, the bus controller controls the electromagnetic coil 301 corresponding to the cable 5 of the device to be energized. After the electromagnetic coil 301 is energized, it generates the same magnetic pole as the corresponding permanent magnet 4011, and the conductive rod 401 is pushed out of the insulating plug 3 by the permanent magnet 4011, so that the conductive rod 401 is separated from the plug 501, and the current between the bus and the abnormal operating state device is disconnected, and then a warning signal is sent to the staff for prompting. The bus controller obtains multiple data of the bus through multiple sensors, and after analyzing multiple data based on the abnormal protection model, predicts the future use status of the bus, and generates an early warning to the staff and performs corresponding power-off control according to the prediction results. This protection method can not only perform multi-level segmented control according to the device status, but also perform comprehensive control in combination with the bus state itself, effectively improving the safety of bus use.

[0067] Embodiment 2: The line controller obtains multiple data of the busbar through multiple sensors, analyzes the multiple data based on the abnormal protection model, predicts the future use status of the busbar, and generates an early warning to the staff and performs corresponding power-off control according to the prediction results;

[0068] The establishment of the abnormal protection model includes the following steps:

[0069] After the humidity value of the cavity area between the waterproof cover 103 and the insulating cover 1, the vibration amplitude of the waterproof cover 103, the harmonic anomaly index of the conductive bar 2 and the resistance impedance of the insulating cover 1 are standardized, the busbar anomaly index my is calculated and obtained. The calculation expression is:

[0070] Wherein, ZDS is the vibration amplitude of the waterproof cover 103, XBY is the harmonic anomaly index of the conductive bar 2, ZKD is the resistance impedance of the insulating cover 1, SDK is the humidity value of the cavity area between the waterproof cover 103 and the insulating cover 1, ω1, ω2, ω3, ω4 are respectively the proportional coefficients of the vibration amplitude of the waterproof cover 103, the harmonic anomaly index of the conductive bar 2, the resistance impedance of the insulating cover 1, and the humidity value of the cavity area between the waterproof cover 103 and the insulating cover 1, and ω1, ω2, ω3, ω4 are all greater than 0;

[0071] The larger the bus abnormality index my value is, the more likely it is that the bus will fail in the future. The calculated bus abnormality index my value is compared with the preset abnormality threshold A and abnormality threshold B to complete the establishment of the abnormality protection model, where abnormality threshold A is less than abnormality threshold B. Abnormality threshold A is used to determine whether the bus currently has an abnormality, and abnormality threshold B is used to determine the severity of the bus abnormality.

[0072] The vibration amplitude of the waterproof cover 103 is obtained by a vibration sensor arranged on the waterproof cover 103. The larger the vibration amplitude of the waterproof cover 103 is, the more likely it is that the busbar will be deformed or damaged or the connection will be loose, thus causing an instant power outage.

[0073] The calculation expression of the harmonic anomaly index of conductive bar 2 is: In the formula, I j represents the current amplitude of the j-th order harmonic, I1 represents the amplitude of the fundamental current, and m represents the harmonic order obtained in the conductive bar 2. The harmonic abnormality index of conductive bar 2 is too large, indicating that there is a large harmonic current in conductive bar 2, indicating that the harmonic level is high, which may easily cause overheating of the equipment connected to the busbar;

[0074] The resistance impedance of the insulation cover 1 is obtained by a ground resistance tester. The ground resistance tester includes a current source and two voltage measurement points. The current is injected into the ground grid. By measuring the voltage drop, the resistance value of the ground grid can be calculated. This instrument is usually suitable for measuring the grounding system, including the grounding condition of the insulation cover. The smaller the resistance impedance of the insulation cover 1, the worse the insulation of the insulation cover 1, and the easier it is to cause a short circuit in the equipment.

[0075] The humidity value of the cavity area between the waterproof cover 103 and the insulating cover 1 is obtained by a humidity sensor arranged on the side of the insulating cover 1 close to the waterproof cover 103. Under normal circumstances, when the cable 5 is connected to the busbar, the cable 5 and the busbar connection must first be dehumidified so that the humidity value of the cavity area between the waterproof cover 103 and the insulating cover 1 is close to 0. The larger the humidity value of the cavity area between the waterproof cover 103 and the insulating cover 1, the more it indicates that the waterproof cover 103 is damaged. The larger the humidity value of the cavity area between the waterproof cover 103 and the insulating cover 1, the more likely it is to cause a busbar short circuit.

[0076] The present application uses an abnormal protection model to comprehensively standardize the humidity value of the cavity area between the waterproof cover 103 and the insulating cover 1, the vibration amplitude of the waterproof cover 103, the harmonic abnormality index of the conductive bar 2, and the resistance impedance of the insulating cover 1, and then calculates and obtains the bus abnormality index, which effectively improves the data processing efficiency and can predict the future use status of the bus. Compared with the existing method of detecting faults and issuing warnings, the future use status of the bus is predicted, and early warning and control can be performed before the bus fails, further ensuring the safety of bus use.

[0077] The bus controller obtains multiple data of the bus through multiple sensors. After analyzing the multiple data based on the abnormal protection model, the future usage status of the bus is predicted, including the following steps:

[0078] The busbar controller periodically obtains the humidity value of the cavity area between the waterproof cover 103 and the insulating cover 1, the vibration amplitude of the waterproof cover 103, the harmonic anomaly index of the conductive bar 2, and the resistance impedance of the insulating cover 1;

[0079] Substitute the humidity value of the cavity area between the waterproof cover 103 and the insulating cover 1, the vibration amplitude of the waterproof cover 103, the harmonic anomaly index of the conductive bar 2, and the resistance impedance of the insulating cover 1 into the calculation formula of the busbar anomaly index my in the abnormal protection model to calculate the busbar anomaly index my value;

[0080] If the bus abnormality index my value is ≤ the abnormality threshold A, it is analyzed that there is no abnormality in the bus, and the bus is predicted to be in normal use in the future;

[0081] If the abnormal threshold value A is less than the bus abnormal index my value ≤ the abnormal threshold value B, the bus is analyzed to have a slight abnormality, and the bus is predicted to be in a first-level abnormal usage state in the future;

[0082] If the bus abnormality index my value is greater than the abnormality threshold B, it is analyzed that there is a severe abnormality in the bus, and it is predicted that the bus will be in a secondary abnormal usage state in the future.

[0083] Generating warnings to staff and performing corresponding power outage control based on the prediction results includes the following steps:

[0084] When the busbar is analyzed to have no abnormality and is predicted to be in normal use in the future, the busbar controller does not perform control;

[0085] like Figure 5 As shown, when the bus is analyzed to have a slight abnormality and the bus is predicted to be in a first-level abnormal use state in the future, it indicates that the bus can continue to support the operation of the equipment for a period of time. At this time, the bus controller sends an early warning signal to the staff, and the staff controls the equipment connected to the bus to shut down. The bus controller controls all the electromagnetic coils 301 to be connected to the power supply at the same time. After the electromagnetic coils 301 are energized, they generate the same magnetic poles as the corresponding permanent magnets 4011, and the permanent magnets 4011 push the conductive rod 401 to move out of the insulating plug 3, so that the conductive rod 401 is separated from the plug 501, and the current between the equipment and the bus is disconnected;

[0086] like Figure 5As shown, when the bus is analyzed to have a severe abnormality and it is predicted that the bus will be in a secondary abnormal use state in the future, the bus may fail if it continues to be used, thereby causing failure of the equipment connected to the bus. In order to avoid this situation, the bus controller directly controls all the electromagnetic coils 301 to be connected to the power supply at the same time. After the electromagnetic coils 301 are energized, they generate the same magnetic poles as the corresponding permanent magnets 4011, and the permanent magnets 4011 push the conductive rod 401 to move out of the insulating plug 3, so that the conductive rod 401 is separated from the plug 501, and the current between the equipment and the bus is disconnected;

[0087] More specifically, when the bus is analyzed to have a slight abnormality and the bus is predicted to be in a first-level abnormal use state in the future, it means that the bus can continue to support the operation of the equipment for a period of time. At this time, the bus controller sends an early warning signal to the staff, and the staff controls the equipment connected to the bus to shut down;

[0088] Since it usually takes some time for the staff to control the shutdown of the equipment connected to the bus, for example, it is necessary to wait for the current equipment to complete the specified work or run a cycle before shutting down the equipment, when the bus is analyzed to have a slight abnormality and it is predicted that the bus will be in the first-level abnormal use state in the future, the future use state of the bus may develop from the first-level abnormal use state to the state of no abnormal use and may also develop from the first-level abnormal use state to the second-level abnormal use state. Therefore, after obtaining historical data, the development trend of the bus in the first-level abnormal use state is analyzed. The specific plan is as follows:

[0089] Obtain the bus abnormality index my of all buses in the first-level abnormal usage state during the historical operation of the bus, and calculate the standard deviation and average value of the bus abnormality index;

[0090] The calculation expression of the busbar abnormal index standard deviation MQ is: The average value of the abnormal index of the main line my avg The calculation expression is: Where i = {1, 2, 3, ..., n}, n represents the number of bus abnormality indexes of all buses in the first-level abnormal usage state during the historical operation of the bus, n is a positive integer, my i Indicates the abnormal index value of the ith busbar, my avg It represents the average value of the bus abnormality index. The larger the standard deviation MQ of the bus abnormality index is, the larger the fluctuation range of the bus abnormality index of the first-level abnormal usage state is. The smaller the standard deviation MQ of the bus abnormality index is, the smaller the fluctuation range of the bus abnormality index of the first-level abnormal usage state is.

[0091] The abnormal threshold C is calculated by the abnormal threshold A and the abnormal threshold B, and the abnormal threshold C = (abnormal threshold A + abnormal threshold B) / 2. The abnormal threshold C is used to determine whether the average value of the bus abnormal index of the first-level abnormal use state bus is biased towards the abnormal threshold A or the abnormal threshold B;

[0092] If the average value of the bus abnormality index is ≤ the abnormality threshold C, and the standard deviation of the bus abnormality index is ≤ the standard deviation threshold, it is analyzed that the bus in the first-level abnormal use state is rapidly developing towards a normal trend, then the bus controller controls all electromagnetic coils 301 to operate after T time, and sends T time to the staff to remind the staff to shut down all equipment connected to the bus within T time;

[0093] If the average value of the bus abnormality index is ≤ the abnormality threshold C, and the standard deviation of the bus abnormality index is greater than the standard deviation threshold, it is analyzed that the bus in the first-level abnormal use state is slowly developing towards a normal trend, then the bus controller controls all electromagnetic coils 301 to operate after T / 1.1 time, and sends the T / 1.1 time to the staff, reminding the staff to shut down all equipment connected to the bus within T / 1.1 time;

[0094] If the average value of the bus abnormality index is greater than the abnormality threshold C, and the standard deviation of the bus abnormality index is greater than the standard deviation threshold, it is analyzed that the bus in the primary abnormal usage state is slowly developing towards the secondary abnormality trend, then the bus controller controls all electromagnetic coils 301 to operate after T / 1.3 time, and sends the T / 1.3 time to the staff, reminding the staff to shut down all the equipment connected to the bus within T / 1.3 time;

[0095] If the average value of the bus abnormality index is greater than the abnormality threshold C, and the standard deviation of the bus abnormality index is less than or equal to the standard deviation threshold, it is analyzed that the bus in the first-level abnormal usage state is rapidly developing towards the second-level abnormal trend, then the bus controller controls all electromagnetic coils 301 to operate after T / 1.5 time, and sends the T / 1.5 time to the staff, reminding the staff to shut down all the equipment connected to the bus within T / 1.5 time;

[0096] This application predicts the future usage status of the busbar, so that it can send a warning signal to the staff before the busbar fails, allowing the staff to shut down the equipment in advance to avoid sudden disconnection of the current between the busbar and the equipment, causing the equipment to stop suddenly (a flash stop can easily cause equipment damage).

[0097] Example 3: Please refer to Figure 2 and Figure 3As shown, the intelligent sensing multi-stage adjustment protective busbar described in this embodiment includes an insulating cover 1 and a conductive bar 2 detachably arranged inside the insulating cover 1, a plurality of insulating plugs 3 are fixedly arranged on one side of the insulating cover 1, a reset power connection mechanism 4 is arranged between the insulating plugs 3 and the conductive bar 2, and the number of the reset power connection mechanism 4 is equal to the number of the insulating plugs 3, the reset power connection mechanism 4 includes a conductive rod 401 and a reset spring 404, and one end of the conductive rod 401 is plugged into the insulating plug 3, and the other end of the conductive rod 401 is slidably embedded in the conductive bar 2, and the reset spring 404 is embedded in the device The conductive bar 2 is placed in the conductive bar 2, and one end of the return spring 404 is in contact with the conductive rod 401, so that the conductive rod 401 is normally kept inserted into the insulating plug 3. The outer side of the insulating plug 3 close to the conductive bar 2 is fixedly provided with an electromagnetic ring 301, and the end of the conductive bar 401 close to the insulating plug 3 is fixedly provided with a permanent magnet 4011 corresponding to the position of the electromagnetic ring 301. When the busbar is detected to be abnormal, the electromagnetic ring 301 is connected to the power supply to generate the same magnetic pole as the permanent magnet 4011. Based on the principle of like charges repel each other, the conductive bar 401 is pushed out of the insulating plug 3 by the permanent magnet 4011.

[0098] Since the busbar is in a humid underground environment, it is required to have good waterproof performance. However, improving the waterproof performance of the busbar will lead to a decrease in the heat dissipation of the busbar. Therefore, a number of heat sinks are usually provided on the outside of the insulating cover 1 to dissipate the heat inside the insulating cover 1 and ensure the stable operation of the busbar.

[0099] See also Figure 2 and Figure 4 As shown, both ends of the conductive bar 2 are fixedly connected with a socket 201, and the socket 201 is used to connect the conductive bar 2 to a power source. Both ends of the insulating cover 1 are fixedly provided with a protective cover 101 on the outside, and the socket 201 is located in the protective cover 101, and the protective cover 101 is used to protect the socket 201;

[0100] When the busbar is installed on the busbar bridge preset in the underground environment and connected to the main power supply through the socket 201, the plug 501 at one end of the cable 5 is inserted into the insulating plug 3 and contacts the conductive rod 401 to be energized, and the staff rotates the screw sleeve 502 movably arranged on the outer side of the cable 5 so that the screw sleeve 502 is screwed onto the insulating plug 3 through the thread 303 on the surface of the insulating plug 3, thus completing the connection between the cable and the busbar. In addition, a positioning protrusion 403 is also integrally provided in the middle of one end of the conductive rod 401 close to the insulating plug 3, and the positioning protrusion 403 corresponds to the notch in the middle of the plug 501, so that the contact area between the conductive rod 401 and the plug 501 can be increased by the positioning protrusion 403, further ensuring the stability of power supply;

[0101] Since it is used in a humid underground environment, it is necessary to keep the connection between the cable 5 and the busbar dry for a long time. Therefore, before connecting the cable 5 to the busbar, the staff opens a hole corresponding to the cable 5 on the waterproof cover 103, passes the cable 5 through the waterproof cover 103, and then embeds the annular edge of the waterproof cover 103 into the annular groove 102. Finally, waterproof glue is applied to the annular groove 102 and the annular edge of the waterproof cover 103, and waterproof glue is applied to the contact position between the waterproof cover 103 and the cable 5 to complete the waterproof treatment of the connection between the cable 5 and the busbar. After a series of waterproof treatments, the dryness of the connection between the cable 5 and the busbar can be maintained for a certain period of time. The staff only needs to replace the waterproof cover 103 regularly. The waterproof cover 103 is made of flexible materials, such as rubber and other materials, which are easy to open holes and install.

[0102] See also Figure 3 and Figure 7 As shown, a slider 402 is integrally provided at one end of the conductive rod 401 away from the insulating plug 3, a slide groove 202 corresponding to the slider 402 is provided on the inner side of the conductive bar 2, and the slider 402 is slidably arranged in the slide groove 202, and the arranged slider 402 not only maintains the stability of the movement of the conductive rod 401, but also prevents the conductive rod 401 from moving out of the conductive bar 2;

[0103] A reinforcing rib 302 is fixedly provided on the outer side of the middle part of the insulating plug 3, and the reinforcing rib 302 is used to reinforce the insulating plug 3 and the insulating cover 1 to prevent the insulating plug 3 from loosening due to the insertion of the cable 5.

[0104] See also Figure 8 As shown, in order to improve the adaptability of the busbar, a number of insulating plugs 3 are usually provided. However, in actual use, some insulating plugs 3 are still in an impractical state. If these idle insulating plugs 3 are not processed, water may enter the busbar from the insulating plugs 3, causing a short circuit in the busbar.

[0105] Therefore, we also set a water-blocking plate 304 inside the insulating plug 3, and a rewinding spring 305 is set at the top of the water-blocking plate 304, and the top of the water-blocking plate 304 is movably connected to the insulating plug 3 through the rewinding spring 305. When the insulating plug 3 is not in use, the staff can take out the resetting spring 404 at the resetting power connection mechanism 4 corresponding to the insulating plug 3 (taken out by disassembling the conductive bar 2). In this way, after the conductive rod 401 is moved out of the insulating plug 3, the rewinding spring 305 pushes the water-blocking plate 304 to rotate counterclockwise, so that the water-blocking plate 304 is screwed out of the groove 306 at the top of the inner wall of the insulating plug 3. When the water-blocking plate 304 rotates 90 degrees counterclockwise, the bottom end of the water-blocking plate 304 is embedded in the limiting groove 307 at the bottom of the inner wall of the insulating plug 3. The limiting groove 307 limits the movement of the water-blocking plate 304, so that the water-blocking plate 304 seals the insulating plug 3.

[0106] When the insulating plug 3 is needed, the staff installs the reset spring 404 corresponding to the insulating plug 3, and the reset spring 404 pushes the conductive rod 401 to insert into the insulating plug 3, and the conductive rod 401 pushes the watertight plate 304 to rotate clockwise and screw into the groove 306 for placement.
