Special tool for assembling circuit breaker contact

Abstract

The invention provides a special tool for assembling a circuit breaker contact, which comprises a sleeving piece, a through hole corresponding to a contact process hole is formed in the sleeving piece, the special tool further comprises a plug pin mounted on the sleeving piece, the plug pin is provided with a locking end which penetrates through the through hole and is inserted into the process hole, and a stop structure is arranged on the outer surface of the plug pin. The depth of the bolt inserted into the process hole is limited; the special tool further comprises an elastic piece arranged outside the plug pin, the plug pin is provided with an unlocking station and a locking station, the unlocking station enables the elastic piece to be stressed and deformed when the plug pin is pulled out, the locking end retreats to the position where the sleeving piece can be arranged outside the contact in a sleeving mode or the sleeving piece can be disengaged from the contact, and the locking station enables the locking end to be inserted into the auxiliary hole under the reset acting force of the elastic piece. Mounting or dismounting of the sleeving piece can be achieved by pulling out the plug pin, the locking end can be inserted into the contact auxiliary hole by loosening the plug pin, use is very convenient, the assembling efficiency can be improved, meanwhile, the plug pin is arranged on the sleeving piece, the plug pin can be prevented from being lost, and assembling work can be conveniently carried out.

Description

technical field [0001] The invention relates to the technical field of circuit breaker assembly tooling, in particular to a special tooling for circuit breaker contact assembly. Background technique [0002] High-voltage circuit breakers play two roles in the entire high-voltage transmission and distribution circuit: one is control, that is, according to the needs of grid operation, some electrical equipment or lines are put into or out of operation according to dispatch instructions; the other is protection, That is, when the electrical equipment or circuit fails, the relay protection or automatic device sends a trip signal to disconnect the circuit breaker, quickly remove the faulty equipment or line from the power grid, and ensure the normal operation of the fault-free part of the power grid. [0003] figure 1 Shown is a circuit breaker in the prior art. In the arc extinguishing chamber of the circuit breaker, there are two parts: a static contact assembly 100 and a movi...
