[0014] A method for using a reactive power compensation device that is easy to maintain, comprising the following steps:

[0015] Step 1: The equipment needs to be repaired. The equipment is repaired by opening the No. 1 cabinet door. At the same time, when the No. 1 cabinet door rotates, the fixed plate is driven to rotate. When the No. 1 cabinet door rotates out of the limit of the card slot, the elastic force of the elastic telescopic rod drives the card slot to move upward;

[0016] Step 2: Move the fixing plate upwards through the card slot to clamp the fixing plate, and limit the fixing plate through the card slot to prevent the No. 1 cabinet door from being suddenly closed due to wind or collision during the maintenance process, which may cause the hands of the maintenance personnel to be clamped, affecting the maintenance personnel's maintenance;

[0017] Step 3: Pull the rod downward to push the rotating plate downward. When the rotating plate is separated from the rod, the No. 1 torsion spring drives the rotating plate to reset. At the same time, the limit plate contacts the sliding frame, and the sliding frame blocks the limit plate to prevent the rotating plate from rotating upward. There is no need to pull the rod by hand all the time, which is convenient to operate.

[0018] Step 4: The sliding frame moves away from the pull rod to drive the rotating plate to release the limit on the pull rod. The elastic force of the elastic telescopic rod itself drives the card slot to reset. Resetting the card slot can facilitate the next maintenance and improve the maintenance efficiency and safety of the equipment.

[0019] The present invention provides a reactive power compensation device and method that are easy to maintain, and has the following beneficial effects:

[0020] (1) The invention limits the fixed plate by means of a card slot to prevent the No. 1 cabinet door from being suddenly closed due to wind or collision during maintenance, which may cause the hands of the maintenance personnel to be pinched, thus affecting the maintenance personnel's maintenance. At the same time, the limit plate will contact the sliding frame, and the sliding frame will block the limit plate to prevent the rotating plate from rotating upward. There is no need to pull the pull rod by hand all the time, and the operation is convenient. The sliding frame moves away from the pull rod, which will drive the rotating plate to release the limit on the pull rod, so that the elastic force of the elastic telescopic rod itself drives the card slot to reset. The reset of the card slot can facilitate the next maintenance, thereby improving the maintenance efficiency and safety of the equipment.

[0021] (2) The invention, through the resetting of the sliding seat, will drive the hollow rod and the sealing ring to be discharged through the liquid inlet hole, and the liquid will flow out slowly, preventing excessive force from being used when closing cabinet door No. 1, which will cause damage to cabinet door No. 1. The movement of the support seat toward cabinet door No. 2 will drive the rotating plate toward cabinet door No. 2, and the movement of the rotating plate toward cabinet door No. 2 will push the fixed seat and cabinet door No. 2 to rotate. During maintenance, cabinet door No. 1 and cabinet door No. 2 can be opened at the same time to inspect the inside of the chassis, so that maintenance personnel can inspect the inside of the chassis from two directions at the same time, thereby improving maintenance efficiency.

[0022] (3) In this invention, the upward rotation of the turntable will drive the turntable to rotate downward, and the downward rotation of the turntable will drive the conductive rod to rotate downward. The conductive rod will rotate downward and contact the ground to prevent static electricity from damaging the electronic components during maintenance. At the same time, the downward movement of the push block will push the rotating plate to open. The rotating plate can prevent moisture from the bottom from entering the inside of the chassis and causing a short circuit in the equipment. At the same time, the rotating plate provides protection for the conductive rod, thereby increasing the service life of the conductive rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] A method for using a reactive power compensation device that is easy to maintain, comprising the following steps:

[0035] Step 1: When the equipment needs to be repaired, the first cabinet door 6 is opened to repair the equipment. When the first cabinet door 6 rotates, the fixing plate 8 is driven to rotate. When the first cabinet door 6 rotates out of the limit of the card slot 10, the elastic force of the elastic telescopic rod 9 drives the card slot 10 to move upward;

[0036] Step 2: Move the fixing plate 8 upwards through the card slot 10 to clamp the fixing plate 8, and limit the fixing plate 8 through the card slot 10 to prevent the No. 1 cabinet door 6 from being suddenly closed due to wind or collision during the maintenance process, which may cause the hands of the maintenance personnel to be clamped, affecting the maintenance personnel's maintenance;

[0037] Step 3: Pull the rod 11 downward to push the rotating plate 13 to rotate downward. When the rotating plate 13 is separated from the rod 11, the first torsion spring drives the rotating plate 13 to reset. At the same time, the limit plate 14 contacts the sliding frame 12. The sliding frame 12 blocks the limit plate 14 to prevent the rotating plate 13 from rotating upward. There is no need to pull the rod 11 by hand all the time, which is convenient to operate.

[0038] Step 4: The sliding frame 12 moves away from the pull rod 11 to drive the rotating plate 13 to release the limit on the pull rod 11. The elastic force of the elastic telescopic rod 9 drives the slot 10 to reset. Resetting the slot 10 can facilitate the next maintenance and improve the maintenance efficiency and safety of the equipment.

[0039] When the present embodiment is working: when it is necessary to inspect the equipment, the equipment is inspected by opening the No. 1 cabinet door 6. At the same time, when the No. 1 cabinet door 6 rotates, it will drive the fixed plate 8 to rotate. When the No. 1 cabinet door 6 rotates out of the limit of the card slot 10, the elastic force of the elastic telescopic rod 9 drives the card slot 10 to move upward. The upward movement of the card slot 10 will jam the fixed plate 8. The fixed plate 8 is limited by the card slot 10 to prevent the No. 1 cabinet door 6 from being subjected to wind or collision during the inspection process. The sudden closing of the No. 1 cabinet door 6 may cause the hands of the personnel who are inspecting to be clamped, affecting the inspection of the maintenance personnel. At the same time, when the first cabinet door needs to be closed, the pull rod 11 is pulled downward. The downward movement of the pull rod 11 will push the rotating plate 13 to rotate downward. When the rotating plate 13 is separated from the pull rod 11, the No. 1 torsion spring will drive the rotating plate 13 to reset. When the first cabinet door 6 is closed, the sliding rod 15 will be pushed to move downward, and the downward movement of the sliding rod 15 will drive the short plate 16 to move downward, and the downward movement of the short plate 16 will push the triangular block 17 to move away from the pull rod 11, and the movement of the triangular block 17 away from the pull rod 11 will drive the sliding frame 12 to move away from the pull rod 11, and the movement of the sliding frame 12 away from the pull rod 11 will drive the rotating plate 13 to release the limit on the pull rod 11, so that the elastic force of the elastic telescopic rod 9 itself drives the card slot 10 to reset. Resetting the card slot 10 can facilitate the next maintenance, thereby improving the maintenance efficiency and safety of the equipment.

[0046] When this embodiment is working: the connection seat 181 is driven to rotate by the rotation of the No. 1 cabinet door 6, and the rotation of the connection seat 181 will pull the connecting rod 182 to move in the direction away from the compensator 3, and the movement of the connecting rod 182 in the direction away from the compensator 3 will drive the sliding seat 183 to move in the direction away from the compensator 3, and the movement of the sliding seat 183 in the direction away from the compensator 3 will pull the hollow rod 184 to move in the direction away from the compensator 3, and the movement of the hollow rod 184 in the direction away from the compensator 3 will pull the sealing ring 186 to move in the direction away from the compensator 3, and the movement of the sealing ring 186 in the direction away from the compensator 3 will squeeze the liquid inside the hydraulic pipe 185 into the hollow rod 184 through the liquid inlet hole. When the No. 1 cabinet door 6 is closed, the sliding seat 183 is reset to drive the hollow rod 184 and the sealing ring 186 to be discharged through the liquid inlet hole, and the liquid will flow out slowly to prevent the No. 1 cabinet door 6 from being closed. The force used is too great, resulting in damage to cabinet door No. 1 6. The movement of sliding seat 183 in the direction away from compensator 3 will drive pulley frame 187 to move in the direction away from compensator 3. The movement of pulley frame 187 in the direction away from compensator 3 will push sliding plate 188 to move toward cabinet door No. 2 7. The movement of sliding plate 188 toward cabinet door No. 2 7 will push support seat 189 to move toward cabinet door No. 2 7. The movement of support seat 189 toward cabinet door No. 2 7 will drive rotating plate 1810 to move toward cabinet door No. 2 7.

The upward rotation of the turntable 193 will drive the turntable 193 to rotate downward. The downward rotation of the turntable 193 will drive the conductive rod 194 to rotate downward. The conductive rod 194 rotates downward and contacts the ground to prevent static electricity from damaging the electronic components during maintenance. At the same time, the rotation of the turntable 193 will drive the connecting plate 195 to rotate upward. The upward rotation of the connecting plate 195 will push the triangular slide plate 196 to slide downward. The downward sliding of the triangular slide plate 196 will drive the push block 197 to move downward. The downward movement of the push block 197 will push the rotating plate 198 to open. The rotating plate 198 can prevent moisture from the bottom from entering the interior of the chassis 1, causing a short circuit in the equipment. At the same time, the rotating plate 198 provides protection for the conductive rod 194, thereby increasing the service life of the conductive rod 194.
