Problems solved by technology
When the moving contact of the universal circuit breaker is fixed, 3-5 pieces of red dry paper should be placed on the bottom of the fixed aluminum part of the moving contact to ensure the same height and verticality; , will directly affect the installation height and verticality of the contact. The installation process is complicated and requires multiple adjustments, which is time-consuming and laborious; When fixing the bolts, due to the small space of the base, it is impossible to use tools to straighten it, and it is easy to make the bolts tilt into the base holes when fixing the bolts and damage the base

The fixed device is practically used for fixing the aluminum piece on the circuit breaker movable contact, and the fixed device is simple and convenient to operate and has the advantages of simple manufacturing process, cost reduction and the like and is convenient to use.
Description
technical field [0001] The invention relates to the technical field of manufacturing process equipment for an air circuit breaker in a power system, in particular to a fixing device for an aluminum part on a moving contact of a universal circuit breaker. Background technique [0002] When the moving contact of the universal circuit breaker is installed on the base, in addition to the installation level, its verticality also needs to be considered. When the moving contact of the universal circuit breaker is fixed, 3-5 pieces of red dry paper should be placed on the bottom of the fixed aluminum part of the moving contact to ensure the same height and verticality; , will directly affect the installation height and verticality of the contact. The installation process is complicated and requires multiple adjustments, which is time-consuming and laborious; When fixing the bolts, because the space of the base is small, it is impossible to straighten it with tools, and it is easy t...
