Description

Technical Field

[0002] The isolating switch is a switching device that is mainly used for "isolating power supply, switching operation, connecting and disconnecting small current circuits" and has no arc extinguishing function. When the isolating switch is in the open position, there is an insulation distance that meets the specified requirements and an obvious disconnection mark between the contacts. When it is in the closed position, it can carry the current under normal circuit conditions and the current under abnormal conditions (such as short circuit) within a specified time. It is generally used as a high-voltage isolating switch, that is, an isolating switch with a rated voltage of more than 1kV. Its working principle and structure are relatively simple, but due to its large usage and high requirements for working reliability, it has a great impact on the design, establishment 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 the circuit without load current. The entry introduces the functions, characteristics, types, applications, error prevention improvements, maintenance, common problems, etc. of the isolating switch, but the existing isolating switches are not convenient for opening, which makes it inconvenient for maintenance personnel to perform maintenance. To solve the above problems, we have launched the following devices. Utility Model Content
