Vacuum circuit breaker overhaul frame

Abstract

The invention discloses a vacuum circuit breaker maintenance frame. The vacuum circuit breaker maintenance frame comprises a machine body, a tool box and rotating wheels; a base is arranged at the lower end of the machine body; rotating wheels are mounted on two sides of the lower end of the base; a motor is mounted at the lower end of the middle of the base; the output end of the motor is connected with a ball screw; limiting rods are arranged on the left side and the right side of the ball screw; a sliding table is arranged at the upper end of the base; the tool box is installed on the upperside of the left end of the sliding table; a door opening is formed in the end, away from the tool box, of the sliding table; and a first step is arranged on the lower side of the right end of the door opening. The vacuum circuit breaker maintenance frame is simple in structure; a reciprocating screw rod structure is arranged between the ball screw rod and the sliding table so as to drive the ball screw rod to rotate through rotation of the motor, then the sliding table on the ball screw rod can slide up and down along with the ball screw rod, and therefore stable operation of the device canbe increased, the danger coefficient of climbing overhauling of workers is reduced, and meanwhile the overhauling difficulty is lowered.

Description

technical field [0001] The invention relates to the field of industry and maintenance technology, in particular to a vacuum circuit breaker maintenance rack. 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 network is more popular. The vacuum circuit breaker is an indoor power distribution device in the 3-10kV, 50Hz three-phase AC system, which 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 For places requiring oil-free, less maintenance and frequent operation, circuit breakers can be installed in central cabinets, double-layer cabinets and fixed cabinets to control and p...

AI Technical Summary

Problems solved by technology

[0003] When the existing vacuum circuit breakers are overhauled, most of them use workers to climb and overhaul. The risk factor and the difficulty of overhaul are relatively high, and it is easy to cause the user to climb restricted in high temperature weather, and the user is more difficult to use , maintenance will limit the maintenance tools carried, which reduces the efficiency of the device and affects the use effect
