Abstract
High temperature rise affects air circuit breaker (ACB).There is a difference between common temperature rise test requirement and practical use.Based on it,this paper emphasizes it is very important to reduce the temperature rise of circuit breaker.This paper analyzed the reasons of the temperature rise produced in ACB,proposed some improved schemes to effectively reduce temperature rise through the design of innovation main circuit component,reducing the contact resistance of circuit and improving air convection effect.It can improve the reliability and safety of ACB.关键词
