Special tool for removing return spring of isolating switch

Abstract

The invention discloses a special tool for dismounting the return spring of a disconnector, which comprises a section of an L-shaped corner piece with a cross section, a U-shaped fixing piece, and fixing bolts. Two positioning nuts, the direction of the screw holes of the positioning nuts is along the length direction of the angle piece, the positioning nuts are used in conjunction with the fixing bolts, the U-shaped opening groove of the U-shaped fixing part faces downward, and the U-shaped opening groove has an arc-shaped bottom. Holes for passing fixing bolts are arranged on the upper part of the U-shaped fixing piece. After adopting the special tool for removing the return spring of the isolating switch of the present invention, manpower can be reduced, safety can be increased, and work efficiency can be greatly improved.

Description

technical field [0001] The invention relates to the field of manufacture and maintenance of a high-voltage isolating switch, in particular to a special tool for removing the reset spring of the isolating switch. Background technique [0002] High-voltage isolating switch is the most widely used high-voltage switchgear in the power system. Since the installation and operating environment of the high-voltage isolation switch are relatively harsh, and it operates in the open air without shelter, it is most directly affected by the environment and climate. With the gradual transition from system to condition-based maintenance system and from manned to unattended, the overhaul cycle of main equipment is gradually extending, so power outages caused by outdoor isolating switches in operation continue to occur, and are on the rise, directly affecting System power supply reliability and security. Nowadays, the defects of isolating switches are gradually increasing, and the impact i...

Problems solved by technology

[0004] There are two problems with this method: 1. It requires two people to operate, which increases the manpower, and requires two people to cooperate tacitly; 2. There is a safety hazard in using manpower to press the gasket, because the elasticity of the return spring is compressed by the inner link pin

When the inner link pin is taken out, the spring elasticity is released. If the manpower is not careful or the cooperation is not good, the gasket is easy to be ejected by the spring and hurt people.
