Description

Technical Field

[0001] The utility model relates to the technical field of isolating switches, in particular to a static contact for a bypass cabinet isolating switch. Background Art

[0002] An isolating switch is a switching device that is primarily used to isolate power sources, perform switching operations, and connect and disconnect low-current circuits, and has no arc-extinguishing function. When the isolating switch is in the open position, the contacts have an insulation distance that meets specified requirements and a clear disconnect mark; when in the closed position, it is a switching device that can carry the current under normal circuit conditions and the current under abnormal conditions within a specified time. It is generally used as a high-voltage isolating switch, that is, an isolating switch with a rated voltage of 1kV or more. Its working principle and structure are relatively simple, but due to its large usage and high requirements for working reliability, it has a significant impact on the design, construction, and safe operation of substations and power plants. 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. The entry introduces the functions, characteristics, types, applications, anti-error improvements, maintenance, common problems, etc. of the isolating switch.

Therefore, if the static contact is not dissipated in time, , it is very easy to cause short circuit and other faults, thereby burning out the equipment.
