Description

Technical Field

[0001] This invention relates to the field of surge arrester technology, and more specifically, to an adaptive combined surge arrester device capable of live-line operation. Background Technology

[0002] Because most power transmission and electrical equipment are located in outdoor environments, surge arresters are installed in power transmission environments to prevent damage caused by lightning overvoltage. Currently, zinc oxide surge arresters are generally used. When subjected to a large lightning current, zinc oxide surge arresters are usually directly broken down and destroyed, making them unusable after one use and requiring timely replacement by power workers.

[0003] In the existing technology, when a surge arrester is damaged by lightning, the only options are to work without power or to work remotely with a remote insulated manipulator while the equipment is energized. However, working without power will affect the surrounding power supply, and working while the equipment is energized means that the lightning protection function of the entire transmission equipment can only be restored after the surge arrester is replaced by the staff. It is impossible to maintain the lightning protection function of the transmission equipment during the period after the surge arrester is damaged and fails. Summary of the Invention

[0004] The purpose of this application is to provide an adaptive combined surge arrester device that can be operated under energized conditions, which solves the technical problem of automatically connecting the auxiliary surge arrester after the main surge arrester fails due to a strike, maintaining the surge protection effect, and also being able to quickly replace the main surge arrester under energized conditions and simultaneously disconnect the auxiliary surge arrester.

[0005] To solve the above-mentioned technical problems, the solution adopted in this application is as follows:

[0006] An adaptive combined surge arrester device capable of live-line operation, mounted on a utility pole, includes a main surge arrester.

[0007] Preferably, the main surge arrester is installed inside a sleeve structure, which is mounted on a utility pole. The bottom of the main surge arrester is connected to a grounding wire, which contacts the ground through the utility pole. The bottom of the main surge arrester is connected to an electrical wire on the utility pole.

[0008] Preferably, the pole is equipped with an auxiliary surge arrester, and the top of the sleeve structure is equipped with a gate arm structure, which is connected to an electromagnetic closing structure, and the electromagnetic closing structure is connected to a grounding wire.

[0009] Preferably, the gate arm structure includes a push rod, one end of which is hinged to the top of the sleeve structure, the other end of which is located above the auxiliary surge arrester, and a gate position slot is fixedly installed on the top of the auxiliary surge arrester.

[0010] Preferably, the electromagnetic closing structure includes a slide cylinder, which is fixed to a pole. A stop is vertically slidably disposed inside the slide cylinder, and an armature is fixed at the bottom of the stop. The bottom of the armature extends through the bottom end of the slide cylinder. An electromagnetic component is disposed below the slide cylinder and is electrically connected to a grounding wire.

[0011] Preferably, one end of the stop head is vertically slidably mounted on the slide cylinder, one end of the flexible pull rope is fixed to one end of the stop head, and the other end of the flexible pull rope is connected to the end of the push rod near the auxiliary surge arrester.

[0012] A gate position opening and closing structure is provided between the sleeve structure and the gate arm structure.

[0013] The gate opening and closing structure includes a limiting base plate, which is located below the guide cylinder. A column is vertically fixed above the limiting base plate. A conical block is vertically slidably fitted on the column. A sheet metal plate is fixed outside the conical block. A sliding plate is vertically fixed on the sheet metal plate. One end of a flexible pull rope is fixed to the top of the sliding plate. The other end of the flexible pull rope is connected to the hinge end of the push rod.

[0014] The main surge arrester is provided with a connector at the bottom, and an explosive release device is fixedly fitted on the connector. The top of the conical block abuts against the bottom of the explosive release device on the connector.

[0015] The top of the column and the bottom of the main surge arrester are coaxially connected and abut against each other, and the diameter of the column is not less than the diameter of the joint.

[0016] The sleeve structure includes a guide tube, which is fixed to the pole. The guide tube is hollow inside and has a through top. The diameter of the main surge arrester is clearance-fitted with the inner diameter of the guide tube.

[0017] The bottom of the guide cylinder is provided with a docking groove, and a matching connector is inserted into the docking groove. The bottom of the matching connector is connected to the grounding wire.

[0018] The main surge arrester is hinged to the top with a ring buckle, and an installation plate is fixedly installed on the outer edge of the top of the guide tube. A vertical bracket is fixed on the installation plate, and the side of the bracket is curved.

[0019] After the main surge arrester is inserted into the guide tube, the height of the ring buckle and the height of the mounting bracket are aligned and matched.

[0020] A spring is also provided inside the slide cylinder. The spring is sleeved outside the armature. The top of the spring is fixedly connected to the bottom end of the stop head, and the bottom of the spring is fixedly connected to the bottom of the slide cylinder.

[0021] The first and second flexible pull ropes are configured as non-conductive flexible ropes.

[0022] The guide cylinder is made of a non-conductive material.

[0023] The gate arm structure also includes mounting plate two.

[0024] The second mounting plate is fixed to the top of the sleeve structure. The second mounting plate is in contact with the upper outer wall of the main surge arrester. One end of the push rod is hinged to the second mounting plate.

[0025] The technical solution of this application has at least the following advantages and beneficial effects:

[0026] This invention combines a main surge arrester and a secondary surge arrester installed in phase-separated configurations. A push rod capable of opening and closing is installed at the bottom of the main surge arrester. Utilizing an electromagnetic component connected to the grounding wire, when the main surge arrester fails due to a lightning strike, the electromagnetic component can generate a magnetic attraction force through the current at the grounding wire, causing the upper armature to move downwards. This allows the push rod to be pulled down via a rope and close the circuit with the secondary surge arrester. By connecting the secondary surge arrester to the failed lightning protection line, the lightning protection effect can be maintained, extending the power transmission protection period before the operator removes and replaces the arrester.

[0027] This invention enables remote, live replacement of the main surge arrester by incorporating a quick-connect guide tube. At the bottom of the main surge arrester are an explosive release device and a vertically sliding conical block. The conical block is connected to the hinged end of a push rod via a sliding plate. When the main surge arrester fails, the explosive release device explodes, causing the conical block to move upwards, which in turn causes the push rod to swing downwards, connecting to the secondary surge arrester. After replacing the main surge arrester, the new explosive release device can press down on the conical block, causing the sliding plate to pull the push rod upwards to reset, automatically disconnecting the secondary surge arrester and maintaining its independence.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] Example

[0038] Please refer to Figures 1-6This invention provides an adaptive combined surge arrester device capable of live-line operation. After a surge arrester is damaged while performing lightning protection work, it automatically connects to a spare, intact surge arrester to maintain lightning protection function until a worker quickly replaces the damaged surge arrester while the power is on. The spare surge arrester is then automatically disconnected for future use. It is installed on a utility pole 1 and includes a main surge arrester 2. The main surge arrester 2 is quick-connected and installed within a sleeve structure 3, which is mounted on the utility pole 1. A grounding wire 4 is connected to the bottom of the main surge arrester 2, and the grounding wire 4 contacts the ground through the utility pole 1. The bottom of the main surge arrester 2 is also connected to the power lines on the utility pole 1. When lightning strikes the utility pole 1, current flows into the main surge arrester 2 and then to the ground through the grounding wire 4, reducing the likelihood of lightning damage to the utility pole 1 and the power lines.

[0039] The sleeve structure 3 includes a guide cylinder 31 and a docking groove 32.

[0040] Specifically, the guide tube 31 is fixedly installed on the pole 1. The guide tube 31 is hollow inside and has a through top. The diameter of the main surge arrester 2 is fitted with the inner diameter of the guide tube 31 with a clearance, so that the main surge arrester 2 can be sent into the interior of the guide tube 31 through the top, maintaining stability and preventing shaking. The bottom of the guide tube 31 is also provided with a docking groove 32, and the bottom of the main surge arrester 2 is also fixedly provided with a connector 21. When the main surge arrester 2 contacts the bottom of the guide tube 31, the connector 21 and the docking groove 32 are inserted and matched. The bottom of the connector 21 is also connected to the grounding wire 4. The guide tube 31 is made of a non-conductive material (such as epoxy resin). The top of the main surge arrester 2 is connected to the power line on the pole 1 through a power conductor.

[0041] In order to allow for non-live operation to replace the main surge arrester 2, a ring 24 is hinged to the top of the main surge arrester 2. The operator can use a special insulated operating rod to hook the ring 24 and thus send the main surge arrester 2 into the guide tube 31 from the ground. An installation plate 22 is fixedly installed on the outer edge of the top of the guide tube 31. A vertical bracket 23 is fixedly installed on the installation plate 22. The side of the bracket 23 is curved. When the main surge arrester 2 is inserted into the guide tube 31, the height of the ring 24 is just aligned with the bracket 23. The operator can use the insulated operating rod to put the ring 24 into the bracket 23 to limit the surge arrester. If the main surge arrester 2 is not inserted into the correct position, the height of the ring 24 will be higher or lower than the bracket 23, making it difficult to put into the bracket 23. The operator can judge whether the main surge arrester 2 is inserted into the correct position by whether the ring 24 can be put into the bracket 23.

[0042] The main surge arrester 2 is a commonly used zinc oxide surge arrester. Under normal power transmission conditions, the main surge arrester 2 is in a high impedance state and basically no current flows. When the wire is subjected to lightning, under huge voltage, the resistance of the main surge arrester 2 drops rapidly and becomes a low impedance state, and the current flows rapidly, thereby conducting the charge generated by the excessive voltage to the ground through the grounding wire 4, maintaining the safe voltage at the wire.

[0043] Because after the main surge arrester 2 is struck by lightning, its zinc oxide section will be directly damaged, thus blocking the normal voltage and causing the pole 1 to lose its lightning protection function. In thunderstorms, due to the influence of lightning and rain, workers are generally unable to quickly reach the damaged location to disassemble and replace the main surge arrester 2. If lightning continues to strike the power line, it will be unable to protect against lightning and the power transmission will be disrupted.

[0044] To address the aforementioned issues, this embodiment provides the following reference: Figures 2-6 A secondary surge arrester 5 is also installed on pole 1, and a gate arm structure 7 is installed on the top of the guide tube 31. The gate arm structure 7 is connected to an electromagnetic closing structure 9, which is connected to a grounding wire 4. When the main surge arrester 2 is struck by lightning and conducts electricity, the grounding wire 4 conducts the charge, and the electromagnetic closing structure 9 is energized. The electromagnetic force drives the gate arm structure 7 to move toward the secondary surge arrester 5, thus closing the circuit. Therefore, after the main surge arrester 2 is damaged by lightning, the secondary surge arrester 5 can be automatically connected to the wire at the main surge arrester 2 through the gate arm structure 7 to continue to maintain the lightning protection function of the entire power supply equipment, providing safe protection time for workers to carry out maintenance and replacement.

[0045] The gate arm structure 7 includes a mounting plate 71, a push rod 72, a moving contact 73, and a gate position groove 74.

[0046] The electromagnetic closing structure 9 includes a slide cylinder 91, a stop head 92, a spring 93, an armature 94, a flexible pull rope 95, and an electromagnetic component 96.

[0047] Specifically, mounting plate 2 71 is fixed to the top of guide tube 31. When the main surge arrester 2 is inserted into the guide tube 31, the upper outer wall of the main surge arrester 2 contacts mounting plate 2 71 (to facilitate current conduction). One end of push rod 72 is hinged to mounting plate 2 71, and the other end of push rod 72 is fixed with moving contact 73, which is located directly above auxiliary surge arrester 5. A gate position slot 74 is fixedly installed at the top of auxiliary surge arrester 5. When the end of push rod 72 with moving contact 73 rotates through the hinge point to engage with gate position slot 74, the main surge arrester 2 and auxiliary surge arrester 5 are connected, and the auxiliary surge arrester 5 is electrically connected to the wire on pole 1 to perform the lightning protection function.

[0048] Specifically, the slide cylinder 91 is fixed to the pole 1. The slide cylinder 91 is hollow inside, with its bottom open. A stop 92 is vertically slidable inside the slide cylinder 91. The diameter of the stop 92 is smaller than the diameter of the bottom of the slide cylinder 91, so that the stop 92 can only slide inside the slide cylinder 91 and will not come out. An armature 94 is fixedly connected to the bottom of the stop 92. The bottom of the armature 94 passes through the bottom of the slide cylinder 91. An electromagnetic component 96 is set below the slide cylinder 91. The electromagnetic component 96 is fixed to the pole 1 and is electrically connected to the grounding wire 4. The bottom of the armature 94 is close to the electromagnetic component 96. When the grounding wire 4 conducts electricity, the electromagnetic component 96 will be energized and generate magnetic force (such as an electromagnet), which will magnetically attract and connect the armature 94.

[0049] In addition, a through groove is vertically provided on the slide cylinder 91, and one end of the stop head 92 slides vertically through the through groove, thereby sliding outside the slide cylinder 91. One end of the flexible pull rope 95 is fixedly connected to this end of the stop head 92, and the other end of the flexible pull rope 95 is fixedly connected to one end of the moving contact 73 of the push rod 72.

[0050] Preferably, when the main surge arrester 2 is struck by lightning, the grounding wire 4 becomes conductive, and the electromagnetic component 96 is energized, generating a large magnetic attraction force. This causes the armature 94 to be instantly attracted and moved down to the electromagnetic component 96 for connection. The downward movement of the armature 94 causes the stop head 92 to slide down, thereby simultaneously pulling the flexible pull rope 95. The flexible pull rope 95 then pulls the moving contact 73 of the push rod 72 down into the gate position slot 74, connecting the auxiliary surge arrester 5 to the end of the main surge arrester 2. The auxiliary surge arrester 5 is also connected to the grounding wire 4, thus allowing the auxiliary surge arrester 5 to continue its lightning protection function.

[0051] It is worth noting that, in order to keep the armature 94 and the electromagnetic component 96 separated under normal power transmission conditions, a spring 93 is also provided inside the slide cylinder 91. The spring 93 is sleeved on the outside of the armature 94. The top of the spring 93 is fixedly connected to the bottom end of the stop head 92, and the bottom of the spring 93 is fixedly connected to the bottom of the slide cylinder 91. When the electromagnetic component 96 is not energized, the armature 94 moves upward under the elastic force of the spring 93 and disengages from the electromagnetic component 96 below. When the electromagnetic component 96 is energized, the electromagnetic force on the armature 94 will overcome the elastic force of the spring 93, causing the armature 94 to move downward and connect with the electromagnetic component 96.

[0052] It is worth noting that the flexible pull rope 295 is a non-conductive flexible rope, which can prevent the push rod 72 from being directly connected to the grounding wire 4.

[0053] It is worth noting that although after the grounding wire 4 conducts all the charge to the ground, the electromagnetic component 96 gradually loses its ability to attract the armature 94 due to the disappearance of the current, causing the armature 94 to move upward due to the elastic force, the push rod 72 will not continue to be pushed upward due to the bending of the flexible pull rope 95 between the stop head 92 and the push rod 72, thus preventing the push rod 72 from separating from the auxiliary surge arrester 5 and maintaining the surge protection effect for a long time.

[0054] Although the aforementioned gate structure 7 and electromagnetic closing structure 9 allow the main surge arrester 2 to quickly close with the auxiliary surge arrester 5 via the current conduction effect of the grounding wire 4 and electromagnetic attraction when lightning strikes, enabling the auxiliary surge arrester 5 to connect to the power supply equipment of the pole 1 and continue lightning protection, the push rod 72 cannot be reset due to the separation of the armature 94 and the electromagnetic component 96. Therefore, after the main surge arrester 2 is replaced, it will still be connected to the auxiliary surge arrester 5 via the push rod 72. Consequently, during subsequent lightning strikes, each lightning strike will damage the auxiliary surge arrester 5 simultaneously. Therefore, after replacing the damaged main surge arrester 2, the push rod 72 must be separated from the auxiliary surge arrester 5 to maintain the independence of the auxiliary surge arrester 5.

[0055] To solve the above problems, please refer to Figures 1-6 In this embodiment, a gate position opening and closing structure 8 is also provided between the sleeve structure 3 and the gate rod structure 7. After the new main surge arrester 2 is inserted into the guide tube 31, the push rod 72 at the gate position is simultaneously reset and separated from the auxiliary surge arrester 5.

[0056] The gate opening and closing structure 8 includes a limiting base plate 81, a column 82, a conical block 83, a sheet metal plate 84, a sliding plate 85, a flexible pull rope 86, and a connecting rod 87.

[0057] Specifically, the limiting base plate 81 is located below the guide cylinder 31 and fixed on the pole 1. A column 82 is vertically fixed above the limiting base plate 81. A conical block 83 is vertically slidably fitted on the column 82. The top of the column 82 is coaxially abutted against the bottom connector 21 of the main surge arrester 2. The diameter of the column 82 is not less than the diameter of the connector 21, so that the conical block 83 on the column 82 can slide into the connector 21.

[0058] Specifically, a sheet metal plate 84 is fixedly connected to the outside of the conical block 83. A sliding plate 85 is vertically fixed on the sheet metal plate 84. The upper part of the sliding plate 85 slides vertically through the surface of the mounting plate 71. One end of a flexible pull rope 86 is fixedly connected to the top of the sliding plate 85. The other end of the flexible pull rope 86 is fixedly connected to one end of a pull rod. The other end of the pull rod is hinged to the hinge end of the push rod 72, so that when the sliding rod makes vertical displacement, the push rod 72 can be driven to swing along the hinge point through the flexible pull rope 86.

[0059] An explosion release device 6 is also fixedly fitted on the connector 21. The explosion release device 6 is a common component in the field of surge arresters. When the main surge arrester 2 is broken down by lightning, it can explode and separate internally through the breakdown current (commonly used in drop-out surge arresters).

[0060] Preferably, when the main surge arrester 2 is in a normal power supply environment, the top of the conical block 83 abuts against the bottom of the explosive release device 6 on the connector 21. At this time, the sliding plate 85 is in a low position, and the push rod 72 can be pulled by the flexible pull rope 86 to disengage it from the gate position slot 74. When the main surge arrester 2 is broken down by lightning, the grounding wire 4 conducts current, and the explosive release device 6 explodes, exposing the connector 21 at the bottom of the main surge arrester 2. The conical block 83 can then slide onto the connector 21 (the conical surface can clean the remaining explosive release device 6 shell on the connector 21). The cone block 83 will cause the slide plate 85 to move upward to a high position, so that the flexible pull rope 86 no longer pulls the push rod 72. At the same time, through the magnetic attraction of the electromagnetic closing structure 9, the push rod 72 will swing down into the closing position and connect to the auxiliary surge arrester 5. After the staff replaces the new main surge arrester 2 and inserts it into the guide tube 31, the new explosion release device 6 at the bottom of the main surge arrester 2 will again cause the cone block 83 to move downward, so that the slide plate 85 moves down to a low position, thereby pulling up the push rod 72 again, so that the push rod 72 and the auxiliary surge arrester 5 will automatically separate, maintaining the independence of the auxiliary surge arrester 5.

[0061] It is worth noting that the auxiliary surge arrester 5 is also a commonly used zinc oxide surge arrester, and the flexible pull rope 86 is also a non-conductive flexible rope.

[0062] The various embodiments of the present invention have now been described in detail. To avoid obscuring the concept of the invention, some details known in the art have not been described. Those skilled in the art will fully understand how to implement the technical solutions of this invention based on the above description, and the scope of the invention is defined by the appended claims.
