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.

Abstract

The invention relates to the field of electrician auxiliary equipment, in particular to a discharging device. The discharging device comprises a discharging conductor, a grounding device and an insulating rod, wherein the discharging conductor comprises a fixing frame, an elastic connecting assembly and two discharging parts, the elastic connecting assembly is arranged in the middle of the fixing frame, one discharging part is elastically clamped between one end of the fixing frame and the elastic connecting assembly, the other discharging part is elastically clamped between the other end of the fixing frame and the elastic connecting assembly, and the discharging part can move relative to the fixing frame and is used for discharging two terminals of a capacitor; the grounding device is electrically connected to the discharging conductor; and the insulating rod is movably connected with the discharging conductor. The two terminals of the capacitor are discharged at the same time through the two discharging parts; and under the cooperation of the fixing frame and the elastic connecting assembly, the discharging part can move relative to the fixing frame under the small external force, it is guaranteed that the discharging part makes full contact with the capacitor terminal, the position of the discharging part can be adjusted to adapt to the capacitor, the application force and the work amount of maintainers are reduced, and the discharging efficiency is improved.

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. ...
