Abstract

The invention relates to a capacitor bank grounding device for a high-voltage assembling capacitor bank, which belongs to a repair and maintenance tool for high-voltage transmission equipment. The capacitor bank grounding device comprises an insulating operating rod; a conducting connecting hook is connected with the front end of the insulating operating rod; the conducting connecting hook is connected with a grounding grip holder through a grounding wire; the insulating operating rod is connected with the conducting connecting hook through a connector; the lower end of the connector is connected with the insulating operating rod; the upper end of the connector is connected with the conducting connecting hook through a stud shaft; and the conducting connecting hook can be rotated by taking the stud shaft as a rotating shaft and can be positioned and fixed in different angular positions through a nut. The device has the advantages that the structure is simple, the operation is convenient, and the device can perform electric discharge on a single capacitor in a whole capacitor bank, thereby greatly reducing the power off time in the examine and repair preparation process.

Description

technical field [0001] The invention belongs to a maintenance tool for high-voltage power transmission equipment, and relates to a grounding device for a capacitor bank used in a high-voltage collective capacitor bank. Background technique [0002] The collective capacitors used in ordinary 10kV-35kV substations are divided into three phases: A, B, and C. Each phase is composed of 6-20 small capacitors according to the size of the capacitor capacity. Each small capacitor is composed of a drop-out fuse and the power grid. Connection, the three phases share a set of discharge switches. [0003] At present, there is no special grounding device for discharging a single small capacitor. When a certain capacitor is damaged and the fuse drops, the damaged capacitor cannot be discharged, which brings safety hazards to maintenance personnel. If the entire group of capacitors is discharged through the discharge switch, the discharge time of the capacitors is too long during power out...
