a discharge device

Abstract

The invention relates to the field of electrical auxiliary equipment, in particular to a discharge device, which includes a discharge conductor, a grounding device and an insulating rod. The discharge conductor includes a fixed frame, an elastic connection component and two discharge parts. The elastic connection component is arranged in the middle of the fixed frame. The discharge part is elastically clamped between one end of the fixed frame and the elastic connection component, and the other discharge part is elastically clamped between the other end of the fixed frame and the elastic connection component. The discharge part can move relative to the fixed frame and is used for the capacitor. The two terminals discharge; the grounding device is electrically connected to the discharge conductor; the insulating rod is movably connected to the discharge conductor. Discharge the two terminals of the capacitor at the same time through the two discharge parts; with the cooperation of the fixed frame and the elastic connection component, the discharge part can move relative to the fixed frame under a small external force, which not only ensures that the discharge part is fully in contact with the capacitor terminals, It can also adjust the position of the discharge part to adapt to the capacitor, reduce the effort and workload of the maintenance personnel, and improve the discharge efficiency.

Description

technical field [0001] The invention relates to the field of electrical auxiliary equipment, in particular to a discharge device. Background technique [0002] Shunt capacitors are used in the power system to compensate the reactive power of the inductive load of the power system to improve the power factor and voltage quality, thereby reducing line loss, increasing the output power of the system or transformer, and achieving the purpose of stable system operation. When the capacitor is disconnected and the circuit breaker is disconnected from the power grid, although it has been discharged through its own discharge coil, the capacitor still has residual charge. When the maintenance personnel touch the capacitor, the residual charge will cause the maintenance personnel to get an electric shock. Therefore, in order to ensure the safety of personnel during capacitor maintenance operations, parallel capacitors should be discharged multiple times one by one before maintenance. ...

AI Technical Summary

Problems solved by technology

[0003] When discharging capacitors in existing substations, a discharge rod or ordinary grounding wire is generally used to directly discharge the positive and negative terminals of the capacitor for multiple times, and only one terminal of the capacitor is discharged each time. The positive and negative poles are short-circuited and discharged to the ground, the workload is heavy and it is easy to cause physical strain to the maintenance personnel

At the same time, when the current discharge device discharges the capacitor, in order to ensure that the discharge conductor is in contact with the capacitor terminal, the maintenance personnel must press the insulating rod against the capacitor terminal with force, resulting in laborious operation and low discharge efficiency.
