摘要：To analyze the fault cause of metal parts of isolation switch, a series of tests including macro check, penetrate testing, hardness measurement, composition tests and metallographic observation have been carried out. The experimental results showed that the failure of connecting lever was caused by improper processing, which resulted in the limitation of cracking and stress corrosion cracking. Based on this, the corresponding noteworthy key points were put forward to avoid similar accidents.
