Description

At present, the lightning arrester (discharger) is the main means for lightning protection of electrified railway power supply equipment in China, and is arranged on the power supply network according to geographical position and protection range of the lightning arrester (discharger), when lightning overvoltage occurs in traction power supply equipment, large current will be quickly released overvoltage at the nearest lightning arrester (discharger) from the lightning point, and the lightning arrester (discharger) will immediately restore to the state of insulation to ground after the release. When the traction power supply network is struck by lightning, overvoltage tripping will occur, and the power supply operation will be affected for a short time, and the power supply equipment will be damaged. It is difficult to determine the specific reason for tripping, and only the device manager can arrange to carry out comprehensive inspection along the tripping line, when the lightning-stricken equipment is found, the short-circuit point can be found through the state change of the grounding system of the lightning-stricken equipment after passing through the large current, and the increase of the tripping frequency displayed by the lightning arrester tripping counter can determine that the traction power supply equipment in the section is struck by lightning.

[0003] The staff cannot easily find the lightning point on the ground, and only further inspection of the increase of the number recorded by the tripping counter at the lightning arrester (discharger) point can determine that the tripping in the section is caused by lightning. Such inspection often takes several hours, and even several days, and the situation that the fault point cannot be found also often occurs. The longer the time of the equipment running with faults, the greater the risk of endangering the safety of power supply operation, and only the rapid locking of the equipment fault can take measures to repair the fault equipment quickly and ensure the safety of power supply operation.

[0055] The solar panel 12 supplies power to the management circuit assembly 13 and the overvoltage counter assembly 14.

[0056] Furthermore, the outer shell 11 has a cylindrical structure, and the solar panel 12 is a flexible solar panel in an arc shape, with several panels grouped together and wrapped around the outer wall surface of the outer shell 11 of the device body 1.

[0057] In the utility model, as shown in Figure 4 The solar cell panel 12 is a flexible solar cell panel, so that the solar cell panel can cover the outer lateral wall surface of the shell body, and the space utilization is improved.

[0058] Further, the device body 1 further comprises a base 112 which is installed in abutment with the shell body 11;

[0059] The shell body 11 is internally provided with first fixing columns 1111 and second fixing columns 1112 which are of different lengths, the first fixing columns 1111 are internally threaded structures and are used in cooperation with the first fixing members 1123, and the second fixing columns 1112 are also internally threaded structures and are used in cooperation with the second fixing members 1122 and the sleeves 1121.

[0060] The overvoltage discharge intelligent monitoring device with the above design structure is assembled before use:

[0061] As shown in Figure 5 First, the micro-power supply management unit 131, the overvoltage signal acquisition unit 132 and the wireless signal transmitting unit 133 are connected with each other in pairs to form a management circuit assembly 13, the counting display screen 15 and the real-time current display screen 16 are installed at the openings provided in the shell body 11, and the solar cell panel 12 is sequentially installed on the side wall of the shell body 11 and is fixed by bolts. Then, the second fixing members 1122 are sequentially threaded through the holes provided in the overvoltage counter assembly 14, the sleeves 1121 and the holes provided in the management circuit assembly 13, and are threadedly connected with the second fixing columns 1112 provided in the shell body 11 to form an integral whole, the connecting line of the solar cell panel 12 is connected with the pre-set interface of the management circuit assembly 13, the connecting line on the management circuit assembly 13 is connected with the overvoltage counter assembly 14, the counting display screen 15 is connected with the overvoltage counter assembly 14, the voltage display screen 16 is connected with the management circuit assembly 13. Then, the connecting member 113 is threaded through the pre-set through hole of the base 112 and is connected with the interface of the overvoltage counter assembly 14. The first fixing members 1123 are threaded through the fixing holes provided in the base 112 and are threadedly connected at the first fixing columns 1111 provided in the shell body 11, so that the base 112 and the shell body 11 are connected to form an integral whole, and thus the overvoltage discharge intelligent monitoring device is assembled.

[0062] Before use, as shown in Figure 1 The staff threads the mounting hole provided in the base 112 by bolts, installs the utility model on the support 2, and fixes the support 2 at one side of the stand 3 at a height which is convenient for the staff to observe. The stand 3 is provided with an overvoltage discharger 31 at the top, one end of a grounding wire 32 is connected with the overvoltage discharger 31, the middle part is connected with the connecting member 113 of the utility model, and the other end is grounded, and thus the installation of the utility model before use is completed.

[0063] During use, when there is no lightning strike, under sunlight, such as Figure 2 As shown, this utility model charges the primary energy storage circuit and the secondary energy storage structure in the low-power power management unit 131 through the solar panel 12, ensuring the validity of the data transmitted by the wireless signal transmission unit 133 during subsequent use.

[0064] When a lightning strike occurs, it hits the traction power supply network. The overvoltage is transmitted along the connection line to the overvoltage discharger 31, which quickly releases the voltage. The large current is transmitted along the grounding wire 32 through the bracket 2 to the device body 1, causing the overvoltage counter assembly 14 to run. The count is incremented on the counting display screen 15, and the current magnitude is displayed on the real-time current display screen 16. After the control unit in the low-power power management unit 131 of the management circuit assembly 13 switches from "low power" mode to "running mode", it immediately reads the status of the output node and transmits the data to the overvoltage signal acquisition unit 132. The data is then transmitted to the data monitoring center 4 through the wireless signal transmission unit 133, which is electrically connected to the overvoltage signal acquisition unit 132. After successful data transmission, the control unit controls the device to return to its pre-operation state.

[0065] Finally, the staff received the signal to check the traction power supply network at the lightning strike point. If a trip was found, the staff performed the restoration operation according to the technical specifications.

[0066] Example 2

[0067] Furthermore, the low-power power management unit 131 includes a primary energy storage unit, a secondary energy storage structure, and a control unit. The primary energy storage unit includes a large-capacity capacitor, and the secondary energy storage structure is a lithium battery. The control unit is connected to the capacitor and the lithium battery and can control the charging and discharging of the capacitor and the lithium battery.

[0068] Furthermore, the front of the housing 11 is provided with a counting display screen 15, a real-time current display screen 16 and an EPD display screen. The counting display screen 15 is connected to the overvoltage counter assembly 14, and the voltage display screen 16 and the EPD display screen are connected to the management circuit assembly 13.

[0069] The management circuit component 13 and the overvoltage counter component 14 are electrically connected.

[0070] In this utility model, such as Figure 9As shown, the management circuit component 13 includes a micro-power consumption power management unit 131, an overvoltage signal acquisition unit 132, and a wireless signal transmission unit 133. The micro-power consumption power management unit 131 includes a first energy storage unit, a second energy storage structure, and a control unit. When the solar panel 12 is illuminated, an electric current is generated, and the initial noise is filtered by a filter capacitor. After passing through a self-resetting fuse and a diode, the highest voltage is limited by a voltage stabilizing tube. When the capacitor and the lithium battery are not powered, the current first enters the first energy storage capacitor. When the stored power meets the minimum operating requirements of the control unit, the voltage stabilizing chip and the control unit start to operate. After the control unit is activated, the internal control logic is activated, so that the control unit is intermittently switched between the "operation mode" and the "low-power mode". The operation mode is that the control unit detects and controls each unit module. The low-power mode is to maintain standby state using the least amount of power. When the voltage of the first energy storage capacitor reaches the threshold value, the control unit starts the charging function of the lithium battery, and the electric energy generated by the solar panel 12 is transmitted to the second energy storage lithium battery. When an external overvoltage signal is generated, the first coil circuit of the relay is turned on, so that the output node of the relay is closed. After the control unit is intermittently switched from the "low-power mode" to the "operation mode", the overvoltage signal acquisition unit 132 immediately reads the state of the output node. When the detection result is closed, the control unit starts the voltage boosting function of the voltage boosting chip, so that the voltage of the circuit is lifted to the working voltage range of the wireless signal transmission unit 133. After the voltage is stabilized, the power supply control switch of the wireless signal transmission unit 133 is controlled and opened, and the wireless signal transmission unit 133 is started to transmit relevant data to the data monitoring center 4. After the data transmission is successful, the power supply switch of the wireless signal transmission unit 133 is controlled and closed by the control unit, so as to reduce the overall power consumption of the circuit. After the wireless signal transmission unit 133 stops, the control unit opens the power supply switch of the second coil of the relay, so that the second coil works, and the position of the output node is switched from the closed state to the normally open state, so as to realize the action reset operation of the relay. After the relay is reset, the control unit closes the control switch and the voltage boosting switch of the second coil of the relay, so as to restore the power consumption of the circuit to the state before operation, and realize the low-power operation of the circuit. In this process, when the energy of the capacitor is insufficient to complete one data transmission, the lithium battery is discharged to provide energy to complete the data transmission. If the voltage of the lithium battery is lower than the threshold value, the power supply of the lithium battery is cut off by the discharge protection chip, so as to protect the lithium battery from being powered off. Until the sunlight illuminates the solar panel 12 to generate electric energy, the second cycle of the cycle operation is started.

[0071] Embodiment 3

[0072] Further, the overvoltage signal acquisition unit 132 includes a resistor, a diode, and a relay. The relay is connected to the first coil and the second coil. The first coil and the second coil control the closing and opening of the output node of the relay, respectively.

[0073] In the utility model, as shown in Figure 8 The first coil is used for closing the output node of the relay, and the second coil is used for opening the output node of the relay. The relay first coil is connected in series with a resistor and a diode, and is connected in parallel with the overvoltage discharger 31 and a ground terminal. When an overvoltage and / or a fault overvoltage signal is generated, the residual voltage enters the first coil through the resistor and the diode, so that the first coil generates a magnetic field, and the output node of the relay is triggered to act. The control unit judges the state of the output node in real time, and when the closing action of the output node is detected, the control unit starts the wireless signal transmitting unit 133 to transmit data information to the data monitoring center 4.

[0074] Further, the number and position of the second fixing columns 1112 correspond to the mounting holes formed on the overvoltage counter assembly 14 and the management circuit assembly 13, and the second fixing members 1122 and the sleeves 1121 are installed on the second fixing columns 1112.

[0075] Further, the number and position of the first fixing columns 1111 correspond to the fixing holes formed on the base 112, and the first fixing members 1123 are installed on the first fixing columns 1111.

[0076] Further, the device body 1 is horizontally installed on the support 2 in a horizontal and horizontal manner, so that the solar cell panel 12 is arranged upward.

[0077] In the utility model, as shown in Figure 4 The device body 1 is horizontally installed on the support 2 in a horizontal and horizontal manner, so that the solar cell panel 12 is arranged upward.

[0078] In the utility model, the EPD electrophoretic display technology display screen can keep the content displayed on the EPD display screen unchanged in the case that the device body 1 is damaged due to overvoltage, and the display screen will not be in a non-displaying or display failure state due to disconnection of power.

[0079] In summary, the more specific embodiment of the utility model is:

[0080] As shown in Figure 4 Before a kind of overvoltage discharge intelligent monitoring device is used, the device is assembled first:

[0081] During assembly, the low-power power management unit 131, the overvoltage signal acquisition unit 132, and the wireless signal transmission unit 133 are first interconnected to form a management circuit assembly 13. The solar panels 12 are then sequentially installed on the side wall of the housing 11 and secured with bolts. Next, the second fastener 1122 is sequentially passed through the holes in the overvoltage counter assembly 14, the sleeve 1121, and the management circuit assembly 13, and threaded into the second fixing post 1112 inside the housing 11 to form a single unit. Figure 6 As shown in Figure 7, the solar panel 12 is connected to a pre-set interface of the management circuit assembly 13, and the management circuit assembly 13 is connected to a pre-set interface of the overvoltage counter assembly 14. The counting display 15 is connected to the overvoltage counter assembly 14, and the voltage display 16 and the EPD display are connected to the management circuit assembly 13. Next, a connector 113 is passed through a pre-set through hole in the base 112 and connected to the interface of the overvoltage counter assembly 14. A first fixing member 1123 is passed through a fixing hole in the base 112 and threadedly connected to the first fixing post 1111 inside the outer casing 11, thus connecting the base 112 and the outer casing 11 as a whole. At this point, the assembly of the intelligent overvoltage discharge monitoring device is complete.

[0082] Before use, such as Figure 1 As shown, the worker uses bolts to pass through the mounting holes on the base 112 to horizontally install the utility model onto the bracket 2. The bracket 2 is fixed to one side of the column 3 at a height convenient for the worker to observe. An overvoltage discharger 31 is provided at the top of the column 3. One end of a grounding wire 32 is connected to the overvoltage discharger 31, the middle part is connected to the connector 113 of the utility model, and the other end is grounded. This completes the installation of the utility model before use.

[0083] Among them, such as Figure 9 As shown, the low-power power management unit 131 includes a primary energy storage unit, a secondary energy storage structure, and a control unit; as Figure 8As shown, the overvoltage signal acquisition unit 132 includes resistors, diodes and relays, the relays including first coils and second coils. When the solar panel 12 generates current after being illuminated, the initial noise is filtered by a filter capacitor, the maximum voltage is limited by a voltage stabilizing tube after passing through a self-resetting fuse and a diode, when the capacitor and the lithium battery have no electricity, the current first enters a first energy storage capacitor, when the stored electricity meets the minimum operation requirement of the control unit, the voltage stabilizing chip and the control unit start to operate, after the control unit is started, the internal control logic of the control unit is activated, so that the control unit is intermittently switched between the "operation mode" and the "low power consumption mode". The operation mode is that the control unit detects and controls each unit module. The low power consumption mode is that the minimum electricity is used to keep standby state. When the voltage of the first energy storage capacitor reaches the threshold value, the control unit starts the charging function of the lithium battery, and the electrical energy generated by the solar panel 12 is transmitted to the second energy storage lithium battery. When an external overvoltage signal is generated, the residual voltage enters the first coil after passing through the resistor and the diode, so that the first coil generates a magnetic field, triggers the relay to make the output node closed, the control unit judges the state of the output node in real time, when the closed action of the output node is detected, the control unit is intermittently switched from the "low power consumption mode" to the "operation mode", then the overvoltage signal acquisition unit 132 immediately reads the state of the output node, when the detection result is closed, the control unit controls the voltage boosting chip to start the voltage boosting function, so that the voltage of the circuit is lifted to the working voltage range of the wireless signal transmitting unit 133, after the voltage is stabilized, the control unit controls and opens the power supply control switch of the wireless signal transmitting unit 133, starts the wireless signal transmitting unit 133, transmits relevant data to the data monitoring center 4, after the data transmission is successful, the control unit controls and closes the power supply switch of the wireless signal transmitting unit 133, so as to reduce the overall power consumption of the circuit, after the wireless signal transmitting unit 133 stops, the control unit opens the power supply switch of the second coil of the relay, so that the second coil works, the position of the output node is switched from the closed state to the normally open state, the action reset operation of the relay is realized, after the relay is reset, the control unit closes the control switch and the voltage boosting switch of the second coil of the relay, so that the power consumption of the circuit returns to the state before operation, and the low power consumption operation of the circuit is realized, in the process, when the energy of the capacitor is insufficient to complete one-time data transmission, the lithium battery is discharged to provide energy to complete data transmission, if the voltage of the lithium battery is lower than the threshold value, the discharge protection chip cuts off the power supply of the lithium battery, so that the overall circuit is powered off to protect the lithium battery, until the sunlight illuminates the solar panel 12 to generate electrical energy, and the second cycle of the cycle operation is started.

[0084] Therefore, in the use process, when there is no lightning strike, under sunlight, the one-pole energy storage circuit and the second energy storage structure in the micro-power supply management unit 131 are charged by the solar panel 12, so that the effectiveness of the data transmission of the wireless signal transmitting unit 133 in the subsequent use process is ensured.

[0085] When the lightning stroke occurs, the overvoltage is transmitted to the overvoltage discharge device 31 along the connecting line to release the voltage quickly, and the large current is transmitted to the device body 1 along the grounding wire 32 through the support 2, so that the overvoltage counter assembly 14 operates, the count on the count display screen 15 is increased, and the current size at this time is displayed on the real-time current display screen 16. The running year, month, day, hour, minute, second, surge state, equipment ID number, reporting state and other information are displayed on the EPD electrophoretic display screen. After the control unit in the micro-power supply management unit 131 in the management circuit assembly 13 converts the "low-power" mode to the "running mode", the state of the relay output node is read immediately, the boost chip is controlled to start the boost function, the voltage of the circuit is lifted to the working voltage range of the wireless signal transmitting unit 133, the power supply control switch of the wireless signal transmitting unit 133 is controlled and opened after the voltage is stabilized, data is transmitted to the overvoltage signal acquisition unit 132, and the data is transmitted to the data monitoring center 4 through the wireless signal transmitting unit 133 electrically connected with the overvoltage signal acquisition unit 132. After the data transmission is successful, the power supply switch of the wireless signal transmitting unit 133 is controlled and closed by the control unit, so as to reduce the overall power consumption of the circuit. In this process, when the energy of the capacitor is insufficient to complete one data transmission, the lithium battery is discharged to provide energy to complete the data transmission. If the voltage of the lithium battery is lower than the threshold value, the power supply of the lithium battery is cut off by the discharge protection chip, so that the overall circuit is powered off to protect the lithium battery, and the second cycle of operation is started after the solar cell panel 12 generates electricity under the sunlight.

[0086] Finally, the staff receives the data signal to check the traction power supply network where the lightning stroke occurs, and if the tripping condition is found, the tripping recovery operation is performed according to the technical specification.

[0087] In the utility model, the connection is fixed connection or detachable connection, wherein the fixed connection is welding connection or direct processing into integral molding structure, the detachable connection is internal and external thread connection or clamping connection or plug-in structure connection.
