Abstract

The invention discloses a switch cabinet maintenance linkage mechanism, which comprises a shell. A partition plate is fixedly connected between the top and the bottom of the inner wall of the shell; asupporting plate is fixedly connected between the left side of the partition plate and the left side of the inner wall of the shell; a trolley is arranged at the top of the supporting plate; a trolley switch is arranged at the top of the trolley; the top of the trolley switch is fixedly connected with a joint through a connecting wire; a rotating groove is formed in the supporting plate; a rotating rod is rotatably connected to the surface of the inner wall of the rotating groove through a first fixing shaft; a first transmission shaft is fixedly connected to the bottom of the surface of therotating rod; and the surface of the first transmission shaft passes through a first transmission groove. According to the switch cabinet maintenance linkage mechanism, accidents caused by electrification of the shell during maintenance are avoided, the personal safety of maintenance workers is guaranteed, a grounding busbar can be automatically connected without additional operation, unnecessarytedious operation is reduced, and the maintenance cost is saved.

Description

technical field [0001] The invention relates to the technical field of switch cabinet maintenance, in particular to a switch cabinet maintenance linkage mechanism. Background technique [0002] Medium and high-voltage switchgears in substations are one of the most conventional and important equipment in substations. Medium and high-voltage switchgears are used in the power grid with high frequency and wide distribution, and there are many daily maintenance tasks. In recent years, switching Accidents such as personal injury and death caused by electric shock in the cabinet are mostly caused by staff operating errors and accidental switching of live parts of the cabinet. [0003] During the overhaul of the switchgear, after the handcart switch of the switchgear is shaken to the overhaul position, the rear isolation baffle of the switchgear will be reliably closed as required. The baffle, which leads to accidents. In the existing switchgear, the trolley switch is located in fr...
