[0016] Beneficial effects

[0017] 1. The inclined block provides an automatic connection control function. By compressing the gas, the pressure inside the hollow electrode strip is gradually increased. It first enters the bottom partition and opens the bottom air telescopic rod. The air telescopic rod supports the inclined block. When the inclined block is in contact with the hollow electrode strip, it pushes the sliding contact block to move. The sliding contact block moves towards the positioning template and contacts the spring contact point, connecting the electrode, capacitor and hollow electrode strip to achieve rapid control.

[0018] 2. A vent valve is provided, offering a control structure for disconnection and reset. The control motor drives the lead screw to rotate, which in turn moves the upper frame and the bar valve. After the bar valve moves, it connects the fixed pipe to the vent valve. The spring outside the spring rod rebounds to reset the plate and sliding contact, disconnecting the capacitor. Simultaneously, excess gas flows back into the airbag through the internal fitting pipe of the U-shaped frame, completing the reset.

[0019] 3. The airbag provides a stable power medium circulation function. When the electric cylinder is reset, the gas in the airbag passes through the bellows and one-way valve B to replenish the interior of the piston slide for re-delivery, which can prevent gas leakage. The airbag is filled with inert gas to prevent oxidation. Attached Figure Description

[0031] Example: Please refer to Figures 1 to 8 As shown:

[0032] This invention proposes a capacitor parallel controllable surge arrester device, comprising: an outer casing 1, with two sets of receiving electrodes 101 fixedly disposed in the middle of the outer casing 1, a surge arrester group 102 disposed on the top of the receiving electrodes 101, and a capacitor 103 connected to the outside of the receiving electrodes 101; positioning templates 2, with two sets of positioning templates 2 fixedly disposed on both sides inside the outer casing 1; insulating wrapping shells 3, with two sets of insulating wrapping shells 3 fixedly disposed on both sides inside the outer casing 1; and hollow electrode strips 4. Hollow electrode strip 4 is fixedly disposed in the middle of insulating casing 3; spacer 5 is fixedly disposed between insulating casing 3 and hollow electrode strip 4; fixing tube 6 is fixedly connected to the outside of hollow electrode strip 4; U-shaped frame 7 is fixedly disposed at the top of the inner side of outer casing 1; airbag 8 has a pipe fixedly disposed at the top, and the top of the pipe is fixed to the top of U-shaped frame 7; piston slide 9 is fixedly disposed inside outer casing 1; internal channel 10 is fixedly disposed at the bottom of piston slide 9.

[0033] The positioning template 2 includes a spring contact 201. The spring contact 201 is fixedly installed in the middle of the positioning template 2. The telescopic end of the spring contact 201 is close to the insulating shell 3, and the spring contact 201 does not contact the insulating shell 3.

[0034] The insulating shell 3 includes: a sliding contact 301, which is slidably disposed in the insulating shell 3, and a reset plate 302 is fixedly disposed on the top of the sliding contact 301 near the side of the hollow electrode strip 4; the end of the sliding contact 301 near the spring contact 201 has a T-shaped structure; a spring rod 303, which is fixedly disposed in the insulating shell 3, and a spring is sleeved on the spring rod 303 and a baffle is fixedly disposed through the reset plate 302; and a draw valve 304, which is fixedly disposed in the middle of the side of the sliding contact 301 near the hollow electrode strip 4, and has a through hole 305 in it to provide valve body function. When the through hole 305 moves into the interior of the hollow electrode strip 4, the air in the draw valve 304 can pass through the through hole 305 and continue to be transported upward; the draw valve 304 is slidably disposed in the hollow electrode strip 4.

[0035] The hollow electrode strip 4 includes a spacer strip 401, which is fixedly installed inside the hollow electrode strip 4. A one-way valve A402 is fixedly installed in the middle of the spacer strip 401. The built-in spring pressure of the one-way valve A402 is greater than the spring pressure outside the spring rod 303.

[0036] The partition 5 includes: a gas telescopic rod 501, two sets of gas telescopic rods 501 are fixedly installed on the top of the partition 5, a ramp block 502 is fixedly installed on the top of the gas telescopic rod 501, and a sloping groove that matches the ramp block 502 is opened at the bottom of the sliding contact block 301; an air passage is opened in the partition 5 to connect the hollow electrode strip 4 and the gas telescopic rod 501.

[0037] The U-shaped frame 7 includes: a vent valve 701, with two sets of vent valves 701 fixedly installed at the bottom of both sides of the U-shaped frame 7; the top end of the fixing pipe 6 is connected to the bottom of the vent valve 701; a strip valve 702, which is slidably installed inside the vent valve 701, with an upper frame 703 integrally installed on the top of the strip valve 702; a lead screw 704, which is rotatably installed on the top of the vent valve 701; and a control motor 705, which is fixedly installed on the top of the vent valve 701. The motor 705 is connected to the lead screw 704; the lead screw 704 is threadedly connected to the upper frame 703; the start control motor 705 drives the lead screw 704 to rotate, and the lead screw 704 drives the upper frame 703 and the bar valve 702 to move. After the bar valve 702 moves, it connects the fixed pipe 6 to the vent valve 701. The spring outside the spring rod 303 rebounds to reset the plate 302 and the sliding contact 301, causing the capacitor 103 to disconnect. At the same time, the excess gas flows back into the air bag 8 through the internal fitting pipe of the U-shaped frame 7, completing the reset.

[0038] The piston carriage 9 includes an electric cylinder 901, which is fixedly mounted on the top of the piston carriage 9. A plate piston 902 is fixedly mounted on the bottom telescopic end of the electric cylinder 901. The plate piston 902 slides inside the piston carriage 9. Two sets of one-way valves B903 are connected to the top of the plate piston 902. A bellows 904 is connected to the top of the one-way valves B903. The top of the bellows 904 is connected to the bottom of the airbag 8. When the electric cylinder 901 is reset, the gas in the airbag 8 passes through the bellows 904 and the one-way valves B903 to replenish the interior of the piston carriage 9 for re-delivery.

[0039] The two ends of the built-in channel 10 are connected to the bottom of the two sets of hollow electrode strips 4, and a one-way valve A402 is set at the connection point for one-way communication.

[0040] The specific usage and function of this embodiment: In this invention, the two sets of hollow electrode strips 4 are respectively connected to the output line for use;

[0041] When the number of capacitors 103 to be connected is required, the electric cylinder 901 is activated to drive the plate piston 902 to descend to the designated position, compressing the corresponding volume of gas, which is then fed into the hollow electrode strip 4 through the built-in channel 10 and the bottom one-way valve A402. The gas is gradually pressurized in the hollow electrode strip 4, first entering the bottom partition 5 and opening the bottom air telescopic rod 501. The air telescopic rod 501 supports the ramp block 502. When the ramp block 502 is in contact with the bottom groove of the sliding contact block 301, it pushes the sliding contact block 301 to move. The sliding contact block 301 moves towards the positioning template 2 and is in contact with the spring contact 201, connecting the electrode 101, capacitor 103 and hollow electrode strip 4.

[0042] After the hollow electrode strip 4 is pressurized, the one-way valve A402 is opened in sequence to convey it upward. The above steps are repeated, and the number of capacitors 103 connected is controlled according to the input air pressure.

[0043] When it is necessary to reduce the number of capacitors 103 connected, since the gas cannot flow back directly, it is necessary to exhaust the gas separately.

[0044] The start control motor 705 drives the lead screw 704 to rotate, and the lead screw 704 drives the upper frame 703 and the bar valve 702 to move. After the bar valve 702 moves, it connects the fixed pipe 6 to the vent valve 701. The spring outside the spring rod 303 rebounds to reset the plate 302 and the sliding contact 301, causing the capacitor 103 to disconnect. At the same time, excess gas flows back into the air bag 8 through the internal fitting pipe of the U-shaped frame 7, completing the reset. The U-shaped frame 7 can be installed in reverse to control the sequence in which the capacitor 103 disconnects.

[0045] When the electric cylinder 901 is reset, the gas in the airbag 8 passes through the bellows 904 and the one-way valve B903 to replenish the interior of the piston carriage 9 for resupply.
