Problems solved by technology
However, when components need to be replaced or maintained, the panel needs to be disassembled as a whole
This results in laborious maintenance or component replacement
[0004] Therefore, how to solve the problem of time and energy when maintaining or replacing components is a technical problem that those skilled in the art need to solve

Embodiment Construction
[0025] The present invention will be further described below in conjunction with accompanying drawing.
[0026] Such as figure 1 , figure 2 and image 3 shown. Among them, UV in the figure refers to the module including the rectifying element assembly 9 and the resistance-capacitance absorbing assembly 10, D refers to the module including the freewheeling element assembly 11 and the flow equalizing device 15, the arrows indicate the flow direction of the cooling gas, a, b, and c respectively Indicates a one-phase circuit. The rectifier cabinet of the present invention includes a cabinet body 1 . A first cooling channel 2 is provided in the cabinet body 1 . In a specific embodiment, the first cooling channel 2 includes a first partition 14 , two side plates 4 perpendicular to the first partition 14 , and a first panel opposite to the first partition 14 . A substantially rectangular cooling channel is formed by the first partition 14 , the two side plates 4 and the first ...

The invention discloses a rectifying cabinet which comprises a cabinet body, a module assembly arranged in the cabinet body, first cooling channels, and a cooling device communicated with the first cooling channels, wherein the first cooling channels comprise first partition plates and first panels opposite to the first partition plates; the module assembly comprises rectifying element assemblies arranged in the first cooling channels; and the first panels can be dismounted to maintain or replace the rectifying element assemblies, and consist of a plurality of split first panel parts. When the rectifying element assemblies are required to be replaced or maintained, the first panel parts corresponding to the rectifying element assemblies to be maintained or replaced are directly dismounted, and then the rectifying element assemblies are maintained or replaced without dismounting the whole panels, so that the rectifying cabinet is trouble-saving and labor-saving.
Description
technical field [0001] The invention relates to a rectifier cabinet. Background technique [0002] A rectifier is a device used to convert alternating current to direct current. It can be used in the fields of DC motor speed regulation, generator excitation regulation, electrolysis and electroplating. [0003] Since most of the existing rectifier cabinets are of high power, the components in the cabinet pass through relatively large currents. In this way, the heating of the element due to loss is relatively serious, and in order to make the rectifying element work normally, it is necessary to cool down the element. At present, the rectifier cabinet is generally provided with a cooling channel for passing cooling substances, and components that need to be dissipated are installed in the cooling channel, so that the components can be dissipated. The cooling channel in the prior art generally includes a partition, side plates respectively arranged on both sides of the partit...
