Abstract: The control circuit disconnection is a common defect of the 10 kV VS1 switch. This article analyzed the control circuit disconnection defect of the 10 kV VS1 switch. In addition, it proposed the inspection and processing steps for the control circuit disconnection, which could help operator and maintenance personnel find the cause of the control circuit disconnection. Moreover, this paper combined the daily inspection and standardized maintenance of the switch to propose the related strategy of operation and maintenance to help prevent and reduce the incidence of the control circuit disconnection.
Key words: control circuit disconnection; VS1 switch; coil; blocking electromagnet
