Description

Technical Field

[0001] The utility model relates to the technical field of vacuum circuit breakers, in particular to a novel indoor vacuum circuit breaker. Background Art

[0002] "Vacuum circuit breaker" is named because its arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing are both high vacuum; it has the advantages of small size, light weight, suitable for frequent operation, and arc extinguishing without maintenance, and is widely used in distribution networks. Vacuum circuit breaker is an indoor power distribution device in 3~10kV, 50Hz three-phase AC system. It can be used for protection and control of electrical equipment in industrial and mining enterprises, power plants, and substations. It is particularly suitable for use in places that require oil-free, less maintenance and frequent operation. The circuit breaker can be configured in the central cabinet, double-layer cabinet and fixed cabinet to control and protect high-voltage electrical equipment.

[0003] The vacuum circuit breaker chassis is mainly used to load the circuit breaker in the trolley-type (drawer-type) vacuum circuit breaker and push it in and out; however, the existing vacuum circuit breaker chassis is prone to sliding in the cabinet, causing the vacuum circuit breaker to shake, which in turn leads to poor stability of the vacuum circuit breaker.

[0008] Preferably, mounting plates are provided at the top and bottom of the wheel track, and a plurality of fixing holes are provided on the surface of the mounting plates.

[0009] Beneficial Effects

[0010] The above one or more technical solutions in a novel indoor vacuum circuit breaker provided by the embodiment of the utility model have at least one of the following technical effects:

[0011] Through the above technical scheme, when the utility model is in use, the chassis vehicle is pushed into the chassis frame, so that the insertion rod is inserted into the inspection sleeve, and the first magnet and the second magnet are attracted to each other, thereby playing a limiting and fixing role between the chassis vehicle and the chassis frame, avoiding the chassis vehicle from sliding in the cabinet, thereby avoiding the shaking of the vacuum circuit breaker body, and improving the stability of the vacuum circuit breaker.
