Abstract锛?The secondary circuit plays a more critical role in the operation of the substation. During the operation process锛?if the secondary circuit fails锛?it will directly affect the operation of the equipment. Not only that锛?the failure of the secondary circuit will also cause harm to the entire society. influences. Since the secondary circuit mainly performs the function of connecting the secondary equipment锛?once the accident occurs锛?its influence range is extremely wide and even the primary equipment of the substation will be damaged and a large-scale power outage will occur. The structure of the secondary circuit is more complicated锛?and some potential safety problems cannot be directly detected. At the same time锛?the inspection of the secondary circuit needs to be carried out under full power锛?which requires professionals to troubleshoot and repair. Therefore锛?in order to ensure the normal operation of the secondary circuit锛?a comprehensive analysis of its defects is required to determine the corresponding countermeasures.
