Problems solved by technology
However, after the converter is assembled or delivered to the site, it generally requires continuous debugging. During debugging, it is necessary to operate some power distribution switches, and the power distribution switches are generally installed inside the cabinet. The debugging operation of the power distribution switch can only be carried out after the device is de-energized. The operation is cumbersome, and the inner door panel is also easy to lose during the long-term debugging process.

The invention provides a structure of installing a distribution switch on an internal door of a cabinet, which comprises an internal door sheet, a fixed plate and a guide rail, wherein the internal door sheet is provided with a through hole; the size and the shape of the through hole are matched with those of an operation part of the distribution switch; both ends of the fixed plate are fixed on the back of the internal door sheet and are respectively positioned at both sides of the through hole; a certain distance is reserved between a middle beam of the fixed plate an the internal door sheet; one side of the middle beam, which is close to the internal door sheet, is connected with the guide rail. According to the invention, by installing the distribution switch on the internal door sheet and enabling the operation part of the distribution switch to be exposed out of the right side of the internal door sheet, operation is directly carried out on the distribution switch at the front side of the internal door sheet without disassembling the internal door sheet in the process of debugging a converter, so that the internal door sheet is prevented from being lost; the converter also does not need to be powered off; the structure is convenient and reliable to operate.
Description
technical field [0001] The invention relates to the field of power electronics, in particular to a structure for installing a power distribution switch on an inner door of a cabinet. Background technique [0002] The inner door panels of the converter products are usually fixed directly on the frame of the cabinet to play the role of safety protection or form an air duct. However, after the converter is assembled or delivered to the site, it generally requires continuous debugging. During debugging, it is necessary to operate some power distribution switches, and the power distribution switches are generally installed inside the cabinet. The debugging operation of the power distribution switch can only be carried out after the device is de-energized. The operation is cumbersome, and the inner door panel is also easy to lose during the long-term debugging process. Contents of the invention [0003] The object of the present invention is to solve the above problems, and pro...
