Abstract

Abstract:

The mechanical performance of insulation pull rod is important for the operation reliability of high voltage circuit breaker. This paper takes prototype of high voltage SF₆ tank circuit breaker as the research object, based on mathematical model of the pressure characteristic of chamber, the virtual prototyping of product is built by dynamics simulation software, the dynamic force condition of insulation pull rod is calculated and analyzed in the no-load closing and opening operation of circuit breaker. Then on this basis, the statics and transient dynamic simulation analysis of insulation pull rod are performed by finite element analysis software, the strength of insulation pull rod is checked in closing and opening operation, some suggestions for improvement about force condition and safety coefficient of insulation pull rod are put forward. This research provides a method about force analysis and strength check of product parts, this method is helpful for improve design quality and shorten development period of product, which has very strong application value.

Key words: Circuit breaker, insulation pull rod, force analysis, strength check, safety coefficient
