Abstract

The invention relates to a special disassembly and assembly tool for a contact system of a handcart type circuit breaker, and belongs to the technical field of disassembly and assembly tools for contact systems. The tool comprises a hand wheel, a handle sleeve, a plurality of connecting rod mechanisms and a movable block, wherein the hand wheel is arranged at the end of one side of the handle sleeve, the connecting rod mechanisms are circumferentially arranged at the end of the other side of the handle sleeve in a surrounding mode, an end cover is arranged between the hand wheel and the handlesleeve, a sleeve base is arranged between the connecting rod mechanisms and the handle sleeve, and the end cover and the sleeve base are in threaded connection with the handle sleeve. According to the special disassembly and assembly tool for the contact system of the handcart-type circuit breaker, and the problem that in the prior art, the disassembly and assembly tool special for the contact system is strenuous in rotation is solved.

Description

Technical field[0001]The invention relates to a special disassembly tool for a plum blossom contact of a handcart type circuit breaker, belonging to the technical field of a plum blossom contact disassembly tool.Background technique[0002]The plum blossom contact is the connecting device between the movable contact arm and the static contact of the KYN switch cabinet handcart switch. Due to its special structure, the general disassembly step used in actual work is: press hard on the front of the contact while overcoming the back end. The tightening force of the tension spring pushes the contacts apart, and disassembly and assembly are completed by prying off the springs on the plum blossom (bundled spring type) contacts. The traditional method not only takes time and effort, but also easily damages the plum blossom contacts; while the prior art The torque required for the rotation of the Torx contact disassembly tool is large, and after the tool is used for a long time, the rotation ...
