[0020] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.
[0021] Example 1
[0022] according to Figure 1 、 2 As shown in Figures 3 and 4, this embodiment provides a novel capacitor-specific discharge device, comprising an insulating rod 1 and a first extension rod 2. The first extension rod 2 is movably inserted into the upper end of the insulating rod 1, and a second extension rod 3 is movably inserted into the upper end of the first extension rod 2. A mounting rod 4 is provided on the second extension rod 3, and a rotating rod 5 is rotatably provided on one side of the mounting rod 4. The rotating rod 5 is driven to rotate by a self-locking portion. A fixed guide plate 6 is provided at the upper end of the rotating rod 5, and an adjusting rod 7 is provided at the upper end of the fixed guide plate 6. A special-shaped rod 8 is slidably provided above the adjusting rod 7, and the special-shaped rod 8 is driven to move by a driving portion.
[0023] A movable guide plate 9 is provided at the upper end of the outer side of the special-shaped rod 8, and a short-circuiting rod 10 is provided on one side of the movable guide plate 9 and the fixed guide plate 6, and a guide rod 11 is provided on the other side of the movable guide plate 9 and the fixed guide plate 6. A tensile conductor 12 is connected between the two groups of the guide rods 11, and a grounding component is connected under the fixed guide plate 6. During use, two sets of shorting rods 10 are used to short-circuit capacitors point-to-point. The shorting rods 10 achieve this through the conductive action of the movable guide plate 9, the fixed guide plate 6, the guide rod 11, and the tensile conductor 12. The tensile conductor 12 is stretchable, adapting to the spacing between the two sets of shorting rods 10. The grounding assembly achieves rapid discharge of the capacitor bank. For different capacitors and different connection locations requiring discharge, the self-locking portion can be driven to rotate the rotating rod 5 to change the angle of the shorting rod 10. The drive portion drives the special-shaped rod 8 on the adjustment rod 7 to change the spacing between the movable guide plate 9 and the fixed guide plate 6, thereby adjusting the shorting spacing between the two sets of shorting rods 10. This provides better universal performance. Once the equipment is confirmed to be voltage-free, the maintenance equipment should be immediately grounded and three-phase short-circuited. Furthermore, the full discharge time of each capacitor is controlled within the specified time, which more thoroughly discharges the charge in the capacitor, ensuring the personal safety of maintenance workers, safer operation of related equipment, and shortening the time required for capacitor power outage maintenance.
[0024] A notch is provided on one side of the mounting rod 4. The self-locking portion includes a worm 13 and a worm wheel 14.

An embedded groove is provided below the front end of the mounting rod 4, and a first knob 15 is rotatably provided inside the embedded groove. The lower end axis of the worm 13 extends into the interior of the mounting rod 4 and is connected to the first knob 15. When in use, rotating the first knob 15 drives the worm 13 to rotate, which drives the worm wheel 14 to rotate, thereby driving the rotating rod 5 to rotate and changing the angle of the short-circuit rod 10. This adjustment is performed before short-circuiting discharge.
[0025] The interior of the adjusting rod 7 is hollow, and the driving part includes a second knob 16 and a screw rod 17. The second knob 16 is rotatably arranged at the bottom of the interior of the adjusting rod 7, and the screw rod 17 is arranged above the second knob 16. The screw rod 17 penetrates the interior of the special-shaped rod 8 and is threadedly adapted.

When in use, the screw rod 17 is rotated by passing through the side grooves 18. The special-shaped rod 8 and the adjusting rod 7 are driven to move on the adjusting rod 7 by the action of the thread and the sliding action of the special-shaped rod 8 and the adjusting rod 7, thereby changing the spacing between the movable guide plate 9 and the fixed guide plate 6, thereby adjusting the spacing between the two sets of short-circuiting rods 10. This adjustment is performed before the short-circuit discharge.
[0026] The grounding assembly includes a grounding connector 19 and a grounding wire 20. The grounding connector 19 is connected to one side of the fixed guide plate 6. The grounding wire 20 is connected to the lower end of the grounding connector 19. The lower end of the grounding wire 20 is connected to a grounding conductor 21, which is provided with a screw 22. During use, the grounding conductor 21 is grounded and fixed with the screw 22. The grounding wire 20 is connected to the grounding connector 19 and the fixed guide plate 6 to achieve a discharge effect.
[0027] Example 2
[0028] according to Figure 1 、 2 As shown in Figures 3 and 4, this embodiment provides a novel capacitor-specific discharge device, comprising an insulating rod 1 and a first extension rod 2. The first extension rod 2 is movably inserted into the upper end of the insulating rod 1, and a second extension rod 3 is movably inserted into the upper end of the first extension rod 2. A mounting rod 4 is provided on the second extension rod 3, and a rotating rod 5 is rotatably provided on one side of the mounting rod 4. The rotating rod 5 is driven to rotate by a self-locking portion.

A tensile conductor 12 is connected between the two groups of the guide rods 11, and a grounding component is connected under the fixed guide plate 6. During use, two sets of shorting rods 10 are used to short-circuit capacitors point-to-point. The shorting rods 10 achieve this through the conductive action of the movable guide plate 9, the fixed guide plate 6, the guide rod 11, and the tensile conductor 12. The tensile conductor 12 is stretchable, adapting to the spacing between the two sets of shorting rods 10. The grounding assembly achieves rapid discharge of the capacitor bank. For different capacitors and different connection locations requiring discharge, the self-locking portion can be driven to rotate the rotating rod 5 to change the angle of the shorting rod 10. The drive portion drives the special-shaped rod 8 on the adjustment rod 7 to change the spacing between the movable guide plate 9 and the fixed guide plate 6, thereby adjusting the shorting spacing between the two sets of shorting rods 10. This provides better universal performance. Once the equipment is confirmed to be voltage-free, the maintenance equipment should be immediately grounded and three-phase short-circuited. Furthermore, the full discharge time of each capacitor is controlled within the specified time, which more thoroughly discharges the charge in the capacitor, ensuring the personal safety of maintenance workers, safer operation of related equipment, and shortening the time required for capacitor power outage maintenance.
[0030] The outer side of the insulating rod 1 is covered with an insulating grip 23, and the surface of the insulating grip 23 is provided with anti-slip lines. When in use, the height of the entire device can be stretched and adjusted by the insulating rod 1, the first extension rod 2 and the second extension rod 3. The insulating grip 23 is convenient for manual holding.
[0031] This new capacitor-specific discharge device uses two sets of shorting rods 10 to achieve point-to-point short-circuiting with the capacitors, utilizing a grounding assembly to achieve rapid discharge of the capacitor bank. For different capacitors and different access locations requiring discharge, the self-locking portion can be driven to rotate the rotating rod 5, changing the angle of the shorting rod 10.

This device offers improved general performance, enabling more thorough discharge of charge from the capacitors, ensuring the safety of maintenance personnel and related equipment, and shortening the time required for capacitor power outage maintenance. Furthermore, the device's overall height can be adjusted by adjusting the insulating rod 1, the first extension rod 2, and the second extension rod 3. When using the self-locking portion, simply turning the first knob 15 rotates the worm 13, which in turn drives the worm gear 14.
