Problems solved by technology

[0003] In fact, due to the structural design of the traditional isolating switch, the contact area between the fixed contact and the moving contact is effective, and the reduction of the contact area leads to serious heating when the current passes through the isolating switch. The temperature of the entire isolating switch is difficult to reduce, and there is a risk of being burned. , has a certain security risk

Abstract

The invention relates to the technical field of high-voltage switches, and discloses an isolating switch. The isolating switch comprises a base, a first insulating pillar and a second insulating pillar; a first fixed contact is arranged at the top of the first insulating pillar, a second fixed contact is arranged at the top of the second insulating pillar, a disconnecting link is hinged to the second insulating pillar, one end of the disconnecting link is connected with the second fixed contact, the other end of the disconnecting link is fixedly connected with a moving contact, the first fixed contact is provided with a plurality of fixed grooves, the moving contact is provided with a plurality of moving grooves, the fixed grooves and the moving grooves are arranged in a staggered manner, and the first fixed contact and the moving contact can be engaged with each other through the fixed grooves and the moving grooves; a first insulating seat and a first magnet are arranged in the middle of the disconnecting link, and a second insulating seat and a second electromagnet are arranged on the base. Compared with the prior art, the isolating switch has the advantages that the structural design is ingenious, the heating of the fixed contact and the moving contact is controlled, the service life of the isolating switch is prolonged, the working risk is eliminated, and the use experience is good.

Description

technical field [0001] The invention relates to the field of high-voltage switches, in particular to an isolating switch. Background technique [0002] Isolation switch is a switching device used for isolating power supply, switching operation, connecting and cutting off small current circuits. Isolating switches are widely used in substations, power plants and other places, and are closely related to the design, establishment and safe operation of substations and power plants. [0003] In fact, due to the structural design of the traditional isolating switch, the contact area between the fixed contact and the moving contact is effective, and the reduction of the contact area leads to serious heating when the current passes through the isolating switch. The temperature of the entire isolating switch is difficult to reduce, and there is a risk of being burned. , has a certain security risk. Contents of the invention [0004] In order to solve the above technical problems,...
