Product Description
Isolating switch is a switching device mainly used for "isolating power supply, switching operation, connecting and cutting off small current circuits" and without arc extinguishing function. When the isolating switch is in the open position, there is an insulation distance between the contacts that meets the specified requirements and an obvious disconnection mark.
When in the closed position, it can carry the current under normal circuit conditions and the current under abnormal conditions (such as short circuit) within the specified time.
Current switching equipment. It is generally used as a high-voltage isolating switch, that is, an isolating switch with a rated voltage above 1kV. Its working principle and structure are relatively simple. However, due to its large usage and high working reliability requirements, it requires a lot of attention in the design, construction and construction of substations and power plants. The impact on safe operation is greater. The main feature of the isolating switch is that it has no arc extinguishing ability and can only open and close circuits when there is no load current.
