摘要
Abstract
Faults of 10～35 kV high-voltage switchgear in substation occur from time to time.Therefore,the reasons for the failure are analyzed through practical cases.It is believed that aging of insulating materials,excessive humidity in the cabinet,resulting in condensation and excessive temperature resulting in increased contact resistance of conductive circuits,are the main internal causes of switchgear faults,while lightning overvoltage and arc grounding overvoltage are the main external causes of switchgear faults.Aiming at these failure causes,corresponding preventive measures are put forward.关键词
