Busbar clamping device

Abstract

The invention provides a busbar clamping device. The busbar clamping device comprises: an upper clamping plate; a lower clamping plate, wherein at least one of the opposite end parts of the upper clamping plate and the lower clamping plate is provided with a clamping opening for clamping a busbar; connecting pieces which are used for connecting the upper clamping plate and the lower clamping platetogether to form a frame structure, and the two connecting pieces are located at the left ends and the right ends of the upper clamping plate and the lower clamping plate respectively; and an upper supporting beam and a lower supporting beam which extend in the left-right direction in length, and the left end and the right end are fixedly connected to the switch cabinet. The upper end and the lower end of the connecting piece are connected with the upper supporting beam and the lower supporting beam respectively, the connecting piece can slide left and right along the upper supporting beam and the lower supporting beam to adjust the left-right position of the clamping opening, and fixing structures used for fixing the connecting piece after the connecting piece slides in place are arranged on the upper supporting beam and the lower supporting beam respectively. The busbar clamping device has the advantages that the left-right position of the clamping opening can be adjusted, the clamping opening is aligned with a busbar, clamping of the busbar is achieved, the clamping device does not need to be manufactured again and replaced, and the assembling efficiency of a switch cabinet canbe improved.

Description

technical field [0001] The invention relates to a busbar clamping device. Background technique [0002] In the power transmission and distribution system, medium and low-voltage switchgear is an important type of cabinet. This type of switchgear cabinet is generally assembled from standard profiles. In the cabinet equipped with circuit breakers, it is necessary to carry out support. For example, the switchgear disclosed in the Chinese utility model patent whose authorized announcement number is CN209233225U, the switchgear includes four top beams arranged in a rectangle, four columns and a horizontal busbar assembly, and the horizontal busbar assembly includes a plurality of horizontal copper bars arranged in parallel and two copper bar clips arranged in parallel, the two copper bar clips respectively clamp the two ends of the horizontal copper bar, and the two copper bar clips are respectively installed in the grooves of the two parallel first beams. Specifically, the cop...
