Abstract

The invention relates to the technical field of high voltage switch cabinets, and particularly relates to an adjustable plug, a high voltage switch cabinet dedicated vehicle and a vacuum circuit breaker maintenance device. The adjustable plug comprises a first lead screw and a first nut. A plug is fixedly connected on the first nut. One end along the length direction of the first lead screw is pivotally connected with a connecting part. One side, which is away from the first lead screw, of the connecting part is provided with multiple gear teeth so that the connecting part is enabled to form arack. The length direction of the rack is perpendicular to the length direction of the first lead screw. The adjustable plug also comprises a rotating shaft. A gear is fixedly connected outside the rotating shaft, and the gear and the rack are connected in a matching way. A first rocking handle is fixedly connected on the rotating shaft. The high voltage switch cabinet dedicated vehicle comprisesthe adjustable plug. The vacuum circuit breaker maintenance device comprises the high voltage switch cabinet dedicated vehicle. The invention provides the adjustable plug, the high voltage switch cabinet dedicated vehicle and the vacuum circuit breaker maintenance device, and aims at solving the technical problems in the prior art that the plug on the trolley is not corresponding to the jacks onthe high voltage switch cabinet and the plugging depth of the plug into the jacks is not adjustable.

Description

technical field [0001] The invention relates to the technical field of high-voltage switch cabinets, in particular to an adjustable plug, a special vehicle for high-voltage switch cabinets and a maintenance device for vacuum circuit breakers. Background technique [0002] The overhaul of the vacuum circuit breaker inside the high-voltage switchgear is very troublesome, because it needs to be overhauled outside the high-voltage switchgear, and the circuit breaker is relatively heavy. In actual work, it is necessary to use a trolley, park the trolley in front of the high-voltage switchgear, and make the platform on the trolley correspond to the high-voltage switchgear, pull the vacuum circuit breaker from the inside of the high-voltage switchgear to the platform of the trolley for easy maintenance of the vacuum circuit breaker. [0003] The platform of the trolley has plugs on the side close to the high-voltage switch cabinet. There are two plugs, and the two plugs are arrang...
