Low-voltage switch cabinet top plate

Abstract

The invention discloses a low-voltage switch cabinet top plate, which comprises a cabinet body, wherein a horizontal supporting plate is arranged in the cabinet body; one side, which is far away fromthe inner bottom of the cabinet body, of the supporting plate is fixedly provided with a vertical stand column; one side of the stand column is fixedly provided with a first top cover plate; one side,which is far away from the stand column, of the first top cover plate is fixed on the inner side wall of the cabinet body; the upper end of one side, which is far away from the first top cover plate,of the cabinet body is provided with a notch; the side wall of the notch is rotatably connected with a spindle; the spindle is connected with a second top cover plate through a connecting block; andone side, which is near the second top cover plate, of the stand column is provided with a stop block and a first installation groove. The top plate has a simple structure and is convenient in use, the low-voltage switch cabinet can be prevented from deforming in a hoisting process through the supporting of the supporting plate, the top cover plate is divided into two parts so as to bring convenience in carrying out later-period maintenance on the internal equipment of the low-voltage switch cabinet in a narrow distribution room, and the top cover plate is convenient in fixing so as to be favorable for protecting internal equipment.

Description

technical field [0001] The invention relates to the technical field of low-voltage switch cabinets, in particular to a top plate of a low-voltage switch cabinet. Background technique [0002] Low-voltage switchgear is suitable for power plants, petroleum, chemical industry, metallurgy, textiles, high-rise buildings and other industries. It is used for power transmission, power distribution and power conversion. In order to facilitate wiring, the low-voltage switchgear generally sets the busbar on the top of the switchgear. In one of the compartments, it is usually covered with a top cover plate. The structure of the traditional top cover plate wins a whole piece of steel plate, which makes it easy to cause deformation of the top cover plate when hoisting the low-voltage switchgear, thus affecting the quality of the entire low-voltage switchgear. At the same time, after the cabinet assembly is completed at the work site, it is difficult to open the top cover in the narrow pow...

[0002] Low-voltage switchgear is suitable for power plants, petroleum, chemical industry, metallurgy, textiles, high-rise buildings and other industries. It is used for power transmission, power distribution and power conversion. In order to facilitate wiring, the low-voltage switchgear generally sets the busbar on the top of the switchgear. In one of the compartments, it is usually covered with a top cover plate. The structure of the traditional top cover plate wins a whole piece of steel plate, which makes it easy to cause deformation of the top cover plate when hoisting the low-voltage switchgear, thus affecting the quality of the entire low-voltage switchgear. At the same time, after the cabinet assembly is completed at the work site, it is difficult to open the top cover in the narrow power distribution room, resulting in the inability to insert and install the busbars, which brings great inconvenience to later maintenance. It is difficult to fix on the cabinet, and the protection of internal equipment is not in place
