Isolation Switch Factory

An isolating switch is a switch device mainly used for "isolating power, switch operation, and connecting or disconnecting low current circuits" without arc-extinguishing capabilities. When in the open position, the isolating switch has an insulating distance between the contacts that meets regulatory requirements and a clear disconnection indicator; in the closed position, it is capable of carrying the current under normal circuit conditions and the current under abnormal conditions (such as a short circuit) within a specified time. Generally used as a high-voltage isolating switch, which is an isolating switch with a rated voltage of more than 1kV. Its working principle and structure are relatively simple, but due to its high usage volume and stringent reliability requirements, it has a significant impact on the design, establishment, and safe operation of substation and power plants. The main feature of the isolating switch is its lack of arc-extinguishing capability, allowing circuit opening and closing only under no load current conditions. The entry describes the function, features, types, applications, anti-misoperation improvements, maintenance, and common issues of isolating switches.
