Inverter module guiding and positioning device and installation method thereof

Abstract

The invention discloses a frequency converter module guiding and positioning device and an installation method thereof. The device, which provides guiding and positioning for a module, comprises a module installation board which comprises a bottom board portion and a backboard portion; slide rails which are arranged at the two sides of the bottom board portion of the module installation board respectively and provide guiding and positioning for module pushing in; a fixation support which is arranged on the bottom board portion of the module installation board and the side, opposite to the backboard portion, of which is for fixing the module after the module is pushed in; a positioning board which is arranged at the relative inner side of the backboard portion and is provided with a positioning hole; and a positioning pin which is arranged on the backboard portion and provides positioning for smooth insertion of the module, wherein the module is provided with a U-shaped busbar, and the U-shaped busbar is inserted with a T-shaped busbar of the back portion of a cabinet body; and the positioning hole in the positioning board provides insertion positioning for the T-shaped busbar and the U-shaped busbar. The frequency converter module guiding and positioning device and the installation method thereof can prevent the influence of deformation of cabinet during welding on the guiding precision of the module positioning hole and the positioning pin, reduce resistance of the module during push-in installation, and guarantee firm fixation of the module after installation.

Description

technical field [0001] The invention relates to the field of industrial electrical equipment, in particular to a guiding and positioning structure device applied to a frequency converter module of an industrial electrical cabinet and an installation method thereof. Background technique [0002] In the field of industrial transmission inverters, the installation of inverter modules affects the size and spatial pattern of the entire cabinet. Reasonable installation methods can make the cabinet more compact and facilitate the installation and maintenance of the modules. At present, the more common module installation method is to realize the installation through the plug-in structure. When the inverter module is installed, by applying external force to the module, under the action of thrust, the module slides to the installation position along the slide rail, so that the busbar at the back of the cabinet is inserted into the module busbar. A U-shaped busbar is designed on the ...

AI Technical Summary

Problems solved by technology

[0006] (1) In the prior art, the locating pin and the module slide rail are not installed on the same part. Due to the large deformation of the cabinet frame during welding, it is difficult to ensure the guiding accuracy of the locating pin and the slide rail. As a result, when the module is pushed in, The positioning pin cannot accurately enter the positioning hole of the module;

[0007] (2) In the existing technology, due to the influence of the cabinet welding error, when the module is pushed in, repeated adjustments are required to ensure that the T-shaped busbar on the back of the cabinet and the U-shaped busbar on the back of the module are completely inserted. Difficult to adjust due to relatively large and heavy modules

[0008] (3) In the existing technology, the friction resistance between the module and the slide rail is very large, and it is laborious and time-consuming to push the module
