| Abstract: | The main circuit breaker is the main protection and master switch of electrical locomotive.The analysis on the survey results of the running conditions of the main circuit breaker in 2008-2010 shows that 94% faults of the main circuit breaker occurred in the low-voltage operating mechanism,and 98% faults of low-voltage operating mechanism occurred in startup mechanism and electrical chain.And through analyzing the reasons of the faults of the main circuit breaker in the last 3 years,the technical transformation has made for it. |
