Abstract
The fault of circuit breaker is caused by the defect of metal material. A series of tests including design drawings, physical and chemical tests, composition tests and metallographic observation, have been carried out for the failed springs. The experimental results showed that the failure of energy storage springs was caused by combination of design flaws and improper heat treatment process. At the same time, the corresponding noteworthy key points in the process of material production were put forward.
