Simple and easy foldable 10-kilovolt centrally installed switchgear electrical inspection trolley

Abstract

A simple and easy foldable 10-kilovolt centrally installed switchgear electrical inspection trolley relates to the electrical inspection trolley. At present, the electrical inspection trolley has a large volume and is difficult to transport. The electrical inspection trolley comprises a trolley body, an insulating baffle and a safety contact, and is characterized in that a plurality of wheels for moving are arranged on the two sides of the trolley body; a handle is arranged at the rear part of the trolley body; the insulating baffle comprises an upper baffle and a lower baffle; the upper baffle is connected with the lower baffle by a first hinge; the lower baffle is connected with the trolley body by a second hinge; the two sides of the upper baffle are connected with one end of a supporting rod which is vertically arranged and is used for supporting the insulating baffle through a shaft rod connected with the upper baffle; the rear part of the trolley body is fixedly connected with a corner; the other end of the supporting rod is connected with the corner by a third bolt; an electrical inspection hole is formed in the insulating baffle and the safety contact is arranged at the front end of the trolley body; the safety contact is connected with the trolley body by a second bolt and a screw. According to the simple and easy foldable 10-kilovolt centrally installed switchgear electrical inspection trolley, the structure is simple and can be folded, and the operation is convenient.

Description

technical field [0001] The invention relates to an electric testing trolley. Background technique [0002] Electric inspection is very important in the operation of substation. During the operation of electrical equipment outage maintenance, it is required to conduct electrical inspection on the side where the maintenance equipment may receive electricity, so as to confirm that the electrical equipment is installed with the ground wire (or close the ground switch). If there is no voltage, the electric test is the main measure to avoid vicious misoperation accidents caused by the charged grounding wire (closing the grounding switch). And every time the equipment is out of service, it will take a long time to carry out the electrical inspection of the equipment to ensure the safety of the operator and the equipment. The electric inspection trolleys originally configured by the electrical equipment are generally equipped with electric inspection epoxy resin sleeves, and al...

AI Technical Summary

Problems solved by technology

The electric inspection trolleys originally configured by the electrical equipment factory are generally equipped with electric inspection epoxy resin bushings, and all use steel baffles. The hand-operated operating mechanism has a complex structure and slow operation speed. The equipment is heavy, bulky, and difficult to carry. During the operation, the operator spends more time and energy in the power inspection process, and there is still a certain risk of personal injury
