Abstract

The utility model discloses a capacitor bank grounding device, which comprises an insulating operation rod. A conductive connecting hanger is connected to the front end of the insulating operation rod and connected with a grounding chuck by the aid of a grounding wire; and the insulating operation rod is telescopic. The capacitor bank grounding device adopting the technical scheme manufactures the insulating operation rod into a telescopic type, and accordingly can be adjusted in height according to actual needs, thereby being suitable for use by transformer banks of various types.

Description

Capacitor bank grounding device
Technical field
The invention belongs to the repair and maintenance instrument of high voltage power transmission equipment, relate to a kind of capacitor bank grounding device that is used for high pressure integrated capacitor group.
Background technology
The employed integrated capacitor of common 10kV one 35kV transformer station is divided into A, B, c three-phase, every size according to condenser capacity is made up of 6-20 small capacitor, every small capacitor is connected with electrical network by a drop type fuse, the shared one group of discharge plug-in strip of three-phase.
There is not at present special-purpose earthing device to single small capacitor discharge, when certain capacitor damages fuse and falls, can't be to the capacitor discharge that damages, for maintainer's maintenance brings potential safety hazard.If by the discharge plug-in strip whole group capacitor is discharged, capacitor is long discharge time during interruption maintenance, needs more than 15 minutes, according to becoming the operations staff to arrange the overlong time of safety measure, can not drop into operation of power networks as soon as possible, influence idle adjusting, thereby influence rate of qualified voltage.
Application number is 200910264088.7 application for a patent for invention, though a kind of capacitor bank grounding device is also disclosed, when reality is used this device, because the unified size of device, how long can't adapt to occasion, particularly when capacitor group height is inconsistent, cause many inconvenience.
Summary of the invention
The purpose of this utility model provides a kind of adjustable length, thereby can adapt to the capacitor bank grounding device of multiple occasion.
For achieving the above object, the utility model is by the following technical solutions:
The utility model comprises insulating bar, and the front end of insulating bar connects the conduction coupling hook, and the conduction coupling hook connects the ground connection chuck by earth connection, and described insulating bar is an expansion link.
Described insulating bar is connected by joint between the coupling hook with conduction, and the joint lower end is connected with insulating bar, upper end of joint by bolt shaft with conduct electricity coupling hook and be connected.
Adopt the utility model of technique scheme, insulating bar is made concertina type, like this can be according to the practical adjustments height of devices, thus the transformer group that is fit to various models uses.
Description of drawings
Fig. 1 is overall structure figure of the present utility model;
Fig. 2 is the side structure for amplifying schematic diagram of conduction coupling hook.
Embodiment
As shown in Figure 1 and Figure 2, the utility model includes an insulating bar 1, and the insulating bar front end is connected with a conduction coupling hook 2, and conduction coupling hook 2 is connected with a ground connection chuck 4 by one section earth connection 3.Interconnect by joint 5 between insulating bar and the conduction coupling hook, fixedly connected with insulating bar 1 in joint 5 lower ends, joint 5 upper ends are connected with conduction coupling hook 2 by a bolt shaft 6, conduction coupling hook 2 is that rotating shaft is rotated with bolt shaft 6, and passes through nut 7 positioning and fixing in different angle positions.
For adapting to the capacitor group of multiple model, the utility model is designed to the expansion link form with insulating bar 1, and above-mentioned expansion link is made up of the more piece sleeve pipe, and the joint number of sleeve pipe can be set according to the actual requirements, can be three joints, four joints, five joints or even more.
