A trolley for a high-voltage vacuum circuit breaker with adjustable internal space

Abstract

The invention discloses a trolley for a high-voltage vacuum circuit breaker with adjustable internal space, comprising a bottom plate. Two sides of the front end of the bottom plate are fixedly connected with rollers, and two sides of the rear end of the bottom plate are fixedly connected with universal wheels. The trolley is provided with a first slide groove, a fixing plate, a handle, a cabinet,a through slot, a motor, a threaded shank, a threaded sleeve, a movable column, a pull plate, a second placement plate, a first slide block, a second slide groove, a second slide block, a bearing housing, a snap joint and control switch which cooperate with each other, the advantage of adjustable interior space is achieved, the problem that the internal space of the existing high-voltage vacuum circuit breaker trolleys is not adjustable is solved, the internal storage space of the trolley can be increased when the trolley transports more parts of the high-voltage vacuum circuit breaker, the number of times of the transportation by worker is reduced, the labor force of workers is lightened, and the practicability of the trolley is improved.

Description

technical field [0001] The invention relates to the technical field of high-voltage vacuum circuit breakers, in particular to a trolley for high-voltage vacuum circuit breakers with an adjustable inner space. Background technique [0002] "Vacuum circuit breaker" is named because the 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 no maintenance for arc extinguishing. The application in the power grid is relatively popular. The vacuum circuit breaker is an indoor power distribution device in a 3-10kV, 50Hz three-phase AC system. It can be used for the protection and control of electrical equipment in industrial and mining enterprises, power plants, and substations. It is especially suitable for In places requiring oil-free, less maintenance and frequent operation, circuit breakers can be configured in central cabinets, do...
