Problems solved by technology

When the high-voltage equipment is undergoing power outage maintenance or other work, in order to prevent the equipment from suddenly receiving power and the induced voltage generated by the adjacent high-voltage live equipment from harming the human body, and at the same time to discharge the remaining charge of the power-off equipment, it is necessary to temporarily install the equipment before maintenance. The grounding wire is currently mainly connected to the equipment through an insulating rod. If the equipment carries a charge, an arc is likely to occur when the grounding wire is installed, resulting in thousands of degrees of high temperature, which will cause damage to the equipment.

Embodiment approach

[0047] When the present invention is in use, the connecting rod is first connected to the connecting seat. At this time, the head and tail of the multiple rods are threaded to connect the grip rod to the tail of the bottom rod, and the thread is rotated to the opposite one of the rods. Tightly on the top of the connecting rod, tighten the first bolt head on the top sub-rod in the first threaded hole. Then turn on the switch of the permanent magnet lifter to make the permanent magnet lifter into a magnetic state, hold the device with the grounding wire and move it to the electric equipment shell, the permanent magnet lifter provides magnetic force for the iron plate, and the bottom The shell is quickly adsorbed on the shell of the electric equipment. At this time, the contact plate is in contact with the shell of the electric equipment, and the shell of the electric equipment is grounded through the contact of the grounding wire with the ground. The first threaded hole is unscr...

Abstract

The invention provides a novel power system arc-extinguishing earthing device, which mainly relates to the field of power equipment. A novel power system arc-extinguishing earthing device comprises abottom shell, wherein the bottom shell is an insulating shell; A contact plate, wherein the contact plate is an electrically conductive material; A permanent magnet lifter for providing magnetic attraction to an iron plate on a housing of an electric power equipment; A top shell which is detachably and fixedly connected with the bottom shell; Connecting seat; Connecting rod, wherein the connectingrod is a sectional structure; A push rod head, wherein the top part of the push rod head is provided with a sleeve which is matched with a switch of a permanent magnet lifter, and the sleeve is hinged with the push rod head; A ground wire that passes through the side of the bottom / top shell. The invention has the beneficial effects that the grounding wire can be quickly connected to the equipment, the time of arc generation can be reduced, the arc can be elongated through a slit to achieve the arc extinguishing purpose, the instantaneous temperature of the arc generation area can be reduced,and the equipment can be protected.

Description

technical field [0001] The invention mainly relates to the field of power equipment, in particular to an arc extinguishing and grounding device for a power system. Background technique [0002] The stable operation of the power system is a necessary condition to ensure people's daily life and normal production order. With the long-term load operation of the power system, the power equipment will continue to wear out. In order to prevent the occurrence of power failures, the power system regularly conducts circuit breaker maintenance on the equipment . When the high-voltage equipment is undergoing power outage maintenance or other work, in order to prevent the equipment from suddenly receiving power and the induced voltage generated by the adjacent high-voltage live equipment from harming the human body, and at the same time to discharge the remaining charge of the power-off equipment, it is necessary to temporarily install the equipment before maintenance. At present, the g...
