Description

Technical Field

[0001] The utility model belongs to the technical field of isolating switches, and in particular relates to an isolating switch with a heat dissipation structure. Background Art

[0002] An isolating switch is a switching device that is mainly used for "isolating power supplies, switching operations, and 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, 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 without load current. The entry introduces the functions, characteristics, types, applications, anti-error improvements, maintenance, common problems, etc. of the isolating switch.

[0003] In the prior art, when a general isolating switch is in use, the temperature of the knife switch will be too high due to its own reasons. The current cooling method generally adopts increasing the heat dissipation area to dissipate heat, which is costly and has poor cooling effect. Therefore, an isolating switch with a heat dissipation structure is needed to solve the above problem. Utility Model Content
