Abstract

The invention relates to a fully-enclosed switch cabinet busbar grounding device and an application method, belonging to the technical field of electric power overhaul, the busbar grounding device comprises an operation platform mechanism, A chassis truck is arranged above the operation platform mechanism, A panel is fixedly connected to the chassis truck, the panel is fixedly connected with threepillar insulators, each of the three post insulators is fixedly connected with a conductive arm and a movable contact, the three conductive arms are connected with the chassis car by a three-phase short-circuit copper bar and connected with the chassis car by a first grounding copper bar, the three movable contacts are correspondingly connected with the three upper static contacts inside the switch cabinet, The three-phase busbar of the busbar room is in corresponding contact connection with three upper static contacts through branch down leads, and the busbar grounding device effectively solves the problem of incapability of reliable grounding in maintenance of a switch cabinet busbar, effectively solves the personal safety of operating personnel in the maintenance process of a fully-enclosed switch cabinet busbar, and has very good popularization and application prospects.

Description

technical field [0001] The invention relates to the technical field of electric power maintenance, in particular to a grounding device for a bus bar of a fully enclosed switch cabinet and a method for using it. Background technique [0002] Fully enclosed switchgear has many models, many manufacturers, and the most important thing is the large number. It is one of the important main equipment in the current power system. The fully enclosed switchgear is composed of a circuit breaker room, a busbar room, a cable room, and an instrument room. The four rooms of the switchgear are independent and closed, and do not communicate with each other. Power equipment needs to be temporarily separated from the power system during maintenance and must be reliably grounded. However, due to design reasons, when the busbar of a fully enclosed switchgear needs to be repaired, there is no clear, suitable and reliable grounding point on the busbar. This technology The problem seriously affects...
