Description

Technical Field

[0001] The invention relates to the technical field of lightning protection equipment monitoring, in particular to a gapless lightning arrester with remote fault transmission function and a use method thereof. Background Art

[0002] At present, distribution line lightning arresters and equipment lightning arresters can be disassembled and installed under power. For example, patent announcement number CN216215804U "Live installation device for lightning arresters" can realize the disassembly, installation and replacement of the entire lightning arrester without power outage during operation and maintenance, reducing the risk of power outages, improving the reliability of grid operation, and making operation and maintenance easier.

[0003] However, when the lightning arrester of the distribution line and the lightning arrester of the equipment fail, the operation and maintenance personnel cannot be informed in time, and the operation and maintenance personnel cannot obtain the fault information in time, and cannot replace the faulty lightning arrester in time, which makes the line and equipment run in an unprotected state, which is very likely to cause the risk of line and equipment failure;

[0004] In addition, the fault indication functions of existing lightning arresters are all localized, resulting in a large workload for operation and maintenance personnel to inspect and inspect, and it is extremely difficult to find faulty lightning arresters. The next lightning overvoltage will damage the line or equipment, causing great damage. Summary of the invention

[0005] The object of the present invention is to provide a gapless lightning arrester with remote fault transmission and a method of using the same, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A gapless lightning arrester with remote fault transmission includes a lightning arrester body, the upper end of which is connected to the upper part of an insulating support through a live detachable structure;

[0008] A disconnector is installed at the lower end of the arrester body, and the lower part of the disconnector is connected to the lower part of the insulating support through a monitoring remote transmission mechanism;

[0009] The monitoring remote transmission mechanism includes a wireless communication module and a connection structure, wherein the connection structure includes a rotating plate and a supporting plate, wherein the supporting plate is fixed to the lower part of the insulating support, wherein one end of the rotating plate is rotatably connected to the supporting plate, and the other end of the rotating plate is connected to the disconnector;

[0010] A trigger module is arranged on the support plate on the rotation path of the rotating plate, and the trigger module is used to trigger the sending behavior of the wireless communication module.

[0011] Preferably, the trigger module includes a reed switch arranged on the support plate, and a magnet 1 arranged on the rotating plate.

[0012] Preferably, the monitoring remote transmission mechanism further includes a battery box, a PCB board and a battery arranged inside the battery box; one end of the reed switch is connected to the PCB board, and the other end is connected to the battery.

[0013] Preferably, a clamping block is provided between the arrester body and the disconnector, and opposite planes are provided on both sides of the clamping block; a tooling head is also included, and a limiting surface matching the clamping block is provided on the upper inner groove of the tooling head.

[0014] Preferably, it also includes an insulating rod and a sleeve arranged at the end of the insulating rod, wherein the inner cavity of the sleeve is adapted to the mounting nut at the bottom of the disconnector;

[0015] The lower part of the tooling head is detachably plugged into the inner cavity of the sleeve.

[0016] Preferably, a second magnet is provided on the support plate, and the second magnet is magnetically attracted to the rotating plate.

[0017] Preferably, the bolts at the bottom of the insulating support are fixed to the upper plane of the cross arm through a support plate, and the support plate is in a U-shaped structure that matches the cross arm.

[0018] A method for using a gapless lightning arrester with remote fault transmission includes the following steps:

[0019] When the arrester fails, the disconnector separates to make the rotating plate rotate, and the rotating plate rotates to make the magnet approach the reed switch to make the reed switch conduct;

[0020] The reed switch in the on state is energized to send an alarm command to the PCB board;

[0021] After receiving the alarm command, the PCB board sends out a wireless alarm signal through the wireless communication module.

[0022] The operation and maintenance personnel disassemble the arrester body by cooperating the tool head of the disassembly and assembly tool with the block at the bottom of the arrester body;

[0023] Remove the tool head of the disassembly tool, match the sleeve of the disassembly tool with the mounting nut at the bottom of the new arrester body, and install the arrester body on the rotating plate;

[0024] The new arrester body is dragged upwards by the disassembly tool to be inserted into the live disassembly structure.

[0025] Preferably, when the trigger module is not triggered, the monitoring remote transmission mechanism operates in a low power consumption mode;

[0026] When the trigger module is triggered, the monitoring remote transmission mechanism is awakened and exits the low power consumption mode, and at the same time, the signal of the trigger module is judged;

[0027] If the signal from the trigger module is determined to be valid, the disconnector status is reported and an alarm message is pushed;

[0028] If it is determined that the signal from the trigger module is invalid, the monitoring remote transmission mechanism operates in a low power consumption mode.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] When a lightning arrester body fails, the disconnector separates and drives the rotating plate to rotate, so that the magnet approaches the reed switch, and the two nodes of the reed switch are attracted together, so that the circuit is turned on, and the control program pre-loaded in the CPU runs, and the wireless line receives the signal, and the fault information and the fault location are transmitted to the operation and maintenance personnel APP. When the operation and maintenance personnel arrive at the fault site, the tooling head cooperates with the block at the bottom of the lightning arrester body, and then the insulating rod is rotated to remove the lightning arrester body.

[0031] When a distribution line arrester or equipment arrester fails, the operation and maintenance personnel will be informed in a timely manner, allowing them to carry out emergency repairs as soon as possible. At the same time, the gapless arrester can be disassembled and installed under power.

[0032] This enables the live replacement of the arrester body, and the operation and maintenance personnel can carry out emergency repairs and replacements as soon as possible, avoiding the risk of lines and equipment operating in an unprotected state, which may cause the risk of line and equipment failure.

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0045] The live disassembly structure 21 is a prior art, such as patent publication number CN216215804U "Live installation device for lightning arrester".

[0046] Example:

[0047] A gapless lightning arrester with remote fault transmission and a method of using the same, as shown in the attached Figure 1-7 As shown, it includes a lightning arrester body 1, the upper end of the lightning arrester body 1 is connected to the upper end of the insulating support 20 through a live detachable structure 21, a disconnector 3 is installed at the lower end of the lightning arrester body 1, and the lower part of the disconnector 3 is connected to the lower part of the insulating support 20 through a monitoring remote transmission mechanism;

[0048] The monitoring remote transmission mechanism includes a wireless communication module and a connection structure.

[0049] The connection structure includes a rotating plate 5 and a supporting plate 17. The supporting plate 17 is fixed to the lower part of the insulating pillar 20. One end of the rotating plate 5 is rotatably connected to one side of the upper part of the supporting plate 17. The other end of the rotating plate 5 is connected to the lower part of the disconnector 3. The wireless communication module is fixed on the supporting plate 17.

[0050] The trigger module includes a reed switch 12 arranged on a support plate 17, and a magnet 1 9 arranged on a rotating plate 5; a magnet 2 15 is fixedly arranged on the side wall of the support plate 17, and a magnetic member that is magnetically attracted to the magnet 2 15 is arranged on the rotating plate 5;

[0051] The battery box 11 is fixed on the support plate 17. A PCB board and a battery 14 are arranged inside the battery box 11. The CPU and wireless antenna of the wireless communication module are arranged on the PCB board. A SIM card is also arranged on the CPU. The PCB board is connected to one end of the reed switch 12, and the other end of the reed switch 12 is connected to the battery 14.

[0052] A second limiting block 18 is disposed on the supporting plate 17 , and a first limiting block 19 is disposed on the rotating plate 5 .

[0053] During installation, the bolts at the bottom of the insulating support 20 are fixed to the upper plane of the crossarm 16 through the support plate 17, and the U-shaped support plate 17 is just stuck on the side of the crossarm 16; an open groove is provided at the end of the rotating plate 5 connected to the disconnector 3. When a new lightning arrester body 1 is installed, the lower bolts of the disconnector 3 can be slid into the open groove opening, and then the disconnector 3 is fixed to the rotating plate 5 by installing the nut 6 and the threaded connection with the lower bolts of the disconnector 3. Similarly, when disassembling the low-pressure end screw of the disconnector that has detached from the disconnector 3 due to a malfunction, it can also be pulled out from the open groove opening, thereby reducing the difficulty of installation.

[0054] The disassembly and assembly tool includes an insulating rod 8, a sleeve 7 and a tool head 22. The sleeve 7 is fixed to one end of the insulating rod 8. A clamping block 2 is provided between the arrester body 1 and the disconnector 3. Relative planes are provided on both sides of the clamping block 2. The upper inner groove of the tool head 22 is provided with a limit surface matching the clamping block 2. When disassembling the faulty arrester, the limit surface of the tool head 22 just clamps the two relative planes of the clamping block 2 at the bottom of the arrester body 1. The arrester body 1 can be disassembled by rotating the insulating rod 8.

[0055] The lower part of the tooling head 22 adopts a hexagonal shape that matches the inner cavity of the sleeve 7, so that the lower end of the tooling head 22 can be inserted into the inner cavity of the sleeve 22, and then the tooling head 22 and the sleeve 7 are fixedly connected with the jacking screw; the sleeve 7 is selected to be a model that matches the mounting nut 6 at the bottom of the disconnector 3.

[0056] After removing the faulty arrester body 1, remove the tool head 22 as well, then use the sleeve 7 to hold the mounting nut 6 at the bottom of the disconnector 3 of the new arrester body 1 and lift it upwards, slide the bolt position of the disconnector 3 above the mounting nut 6 into the open groove from the open groove opening on one side of the rotating plate 5, and use the disassembly and assembly tool to drag the new arrester body 1 upwards so that the new arrester body 1 is inserted into the live disassembly and assembly structure 21, and the disassembly and assembly tool drives the arrester body 1 to rotate and install it into place with the live disassembly and assembly structure 21, and then the disassembly and assembly tool continues to tighten the mounting nut 6 to fix it.

[0057] Since there are many 4G base station connection devices and the 4G network has a wide coverage, the wireless communication module of the present invention adopts the 4G network. The wireless communication module is pre-loaded with a control program, and the installation address of the protected device can be configured in the control program. When the arrester body 1 fails, the screw at the low-voltage end of the disconnector 3 will be ejected from the spring clip by the impact force, and the disconnector 3 is close to the support plate 17 under the action of the rotating plate 5, and the magnet 9 on the rotating plate 5 is close to the reed switch 12. The magnet 9 and the reed switch 12 cooperate to conduct the reed switch 12, so that the battery 14 is connected to the PCB board through the reed switch 12 in the conducting state, and the sending alarm signal of the wireless communication module is triggered. The wireless communication module starts through the Internet of Things technology, and under the action of the control program, the fault information and the equipment installation position can be transmitted to the APP of the operation and maintenance personnel, and the APP pushes the equipment alarm information to the user. After receiving the alarm signal, the operation and maintenance personnel arrive at the fault site and use a special disassembly and assembly tool to complete the live replacement of the faulty lightning arrester, avoiding the operation risk of the line and equipment in an unprotected state, and reducing the inspection workload of the operation and maintenance personnel.

[0058] like Figure 1 As shown, when installing the new arrester body 1, the disassembly tool drags the mounting nut 6 at the bottom of the new arrester body 1 upward, and at the same time drives the rotating plate 5 to rotate upward. The rotation angle of the rotating plate 5 relative to the support plate 17 is limited by the limit block 18 to avoid too large an upward rotation angle, and to avoid the arrester body 1 moving too high upward to miss the position for inserting the live disassembly structure 21.

[0059] like Figure 2 As shown, the rotation angle of the rotating plate 5 when it rotates close to the supporting plate 17 is limited by the stop block 19, so as to prevent the magnet 1 on the rotating plate 5 from impacting the supporting plate 17 and causing damage, and to prevent the rotating plate 5 from impacting the magnet 2 15 and causing damage. The magnet 2 15 and the magnetic part on the rotating plate 5 are magnetically attracted to each other to prevent the rotating plate 5 from shaking repeatedly.

[0060] A double nut is provided at the bottom of the disconnector 3, a limit plate 4 is provided between the double nuts, a mounting nut 6 is provided below the double nuts, and a limit protrusion corresponding to the limit plate 4 is provided on the support plate 17. The limit protrusion adopts a magnet bolt that is integrated with the magnet 9, and the magnet bolt is threadedly connected to the rotating plate 5, and the magnet bolt part protruding from the rotating plate 5 can be used as a limit protrusion. The double nuts on the disconnector 3 are used to clamp and fix the limit plate 4 to ensure that when the disassembly tool is used to disassemble the low-pressure end screw of the disconnector 3 that has been disengaged, the limit protrusion on the rotating plate 5 can block the limit plate 4, so as to prevent the low-pressure end screw of the disconnector 3 from rotating as a whole when the disassembly tool is rotated to loosen the mounting nut 6, and cannot be disassembled. When disassembling, it is only necessary to loosen the mounting nut 6, and it is not necessary to remove the mounting nut 6, so that the low-pressure end screw of the disconnector 3 can slide out from the open slot opening, thereby reducing the difficulty of disassembly and improving the disassembly efficiency.

[0061] In order to reduce the power consumption of battery 14, in standby mode, the wireless communication module is set to a disconnected state, and a timing module is provided to wake up the wireless communication module at a regular time, so as to send the battery 14 power to the operation and maintenance personnel at a regular time. When the battery 14 power is too low, the control program can control the push information to remind the operation and maintenance personnel to replace the battery.

[0062] A low-power mode is built into the control program. When the trigger module is not triggered, the monitoring remote transmission mechanism runs in low-power mode to save power.

[0063] Due to the existence of false triggering, when the trigger module is triggered, the monitoring remote transmission mechanism is awakened and exits the low power consumption mode, and the signal of the trigger module is judged at the same time;

[0064] If the signal from the trigger module is determined to be valid, the disconnector status is reported and an alarm message is pushed;

[0065] If the signal from the trigger module is judged to be invalid, the monitoring remote transmission mechanism operates in a low power consumption mode;

[0066] The signal of the trigger module can be judged to be valid if any of the following conditions are met:

[0067] Condition 1: The reed switch 12 is continuously conducting within a time T (eg, 20 seconds).

[0068] Condition 2: The reed switch 12 is intermittently conducting (the number of alternations is greater than 6 times) within a time T (for example, 20 seconds), and there is a possibility that the reed switch 12 is affected by vibration and alternates between being connected and disconnected within a certain period of time; Figure 8 It is a schematic diagram showing that the reed switch 12 is alternately turned on and off at time T; when the reed switch 12 is turned on, areas S1, S3, S5, and S7 are formed above the X-axis; when the reed switch 12 is turned off, areas S2, S4, S6, and S8 are formed below the X-axis;

[0069] In a short period of time, the frequency of vibration (such as wind) to which the reed switch 12 is subjected does not change much. Therefore, under ideal conditions, the variances of (S1-S2), (S3-S4), (S5-S6) and (S7-S8) are small. If the variance is less than the set value, it means that the reed switch 12 is effectively triggered.
