Cover plate device for electrical control cabinet

Abstract

The invention discloses a cover plate device for an electrical control cabinet. The device comprises a cabinet body, a partition plate is fixed in the cabinet body, an insulating isolation sleeve is inserted into the partition plate, a cover plate is arranged outside the partition plate on one side of the insulating isolation sleeve, and a transverse fixed supporting shaft and a transverse movablesupporting shaft or a transverse movable supporting shaft and a transverse fixed supporting shaft are inserted and fixed at an upper end and a lower end of the cover plate; and arc-shaped guide railsare fixed to inner walls of two sides of the cabinet body. The guide rails comprise two arc-shaped guide rail strips and bolt assemblies arranged at the two ends of the guide rail strips. Each bolt assembly comprises a bolt inserted into the two guide rail strips, a nut connected to one end of the bolt in a threaded mode and a compression spring inserted into the bolt in a sleeving mode. The twoends of the compression spring abut against the nut and the side wall of the guide rail strip respectively, opposite arc-shaped protrusions are formed on the inner wall of the guide rail strip on oneside of the bolt assembly, and the two ends of the movable supporting shaft are inserted between the protrusions and the bolt assembly. The cover plate can be opened and closed conveniently, and positioning can be achieved when the cover plate is opened and closed.

Description

technical field [0001] The invention relates to the technical field of electrical connectors, in particular to a cover device for an electrical control cabinet. Background technique [0002] The switch control cabinet is a kind of electrical equipment, and its main function is to switch, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The outside line of the switch control cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch, and each branch is set according to its needs. The high-voltage interface in the control cabinet is used to connect to the high-voltage line, but the connection between the high-voltage line and the high-voltage interface will be disconnected before assembly or during maintenance, so that the high-voltage interface is exposed, which is likely to cause fatal electric shock to the operator sexual harm.

Problems solved by technology

The high-voltage interface in the control cabinet is used to connect to the high-voltage line, but the connection between the high-voltage line and the high-voltage interface will be disconnected before assembly or during maintenance, so that the high-voltage interface is exposed, which is likely to cause fatal electric shock to the operator sexual harm

In order to prevent the operator from getting an electric shock during the construction process, the existing solution is to install a simple board in front of the high-voltage interface to block it, but if the existing board is not fixedly installed, it will easily skew or fall down, so that the high-voltage interface will still be open , and if the board is fixed, it will cause the board to be disassembled when the high-voltage line needs to be connected later, which is troublesome to use and needs to be improved
