Integrated mounting box for super-power and variable-frequency power supply

Abstract

The invention relates to an integrated mounting box for a super-power and variable-frequency power supply. The integrated mounting box comprises a box body, wherein the box body comprises independently arranged switches, a control chamber, a phase-shifting transformer chamber, a filtering chamber, an IGBT rectifier module integrated chamber and an output protection and connecting chamber, wherein connecting holes for allowing power supply cables to penetrate through are formed in the side walls of the adjacent chambers, bottom air-in windows are formed in the bottom, corresponding to the filtering chamber and the IGBT rectifier module integrated chamber, of the box body, a side air-in window and a side air-out window are arranged on the corresponding two outer side walls of the box body, a filter screen is detachably connected to the air-in window, a steel wire net is mounted on the air-out window, a fan is arranged at an air outlet of the air-out window, and box doors are arranged on the outer side walls, corresponding to all the chambers except the phase-shifting transformer chamber, of the box body. The integrated mounting box can realize the integrated mounting of all the parts of the super-power and variable-frequency power supply and the integral storage and transport of the super-power and variable-frequency power supply and can be rapidly connected and used on site. Meanwhile, the integrated mounting box is compact in structure, reasonable in design and convenient to mount, inspect and maintain.

Description

technical field [0001] The invention relates to an installation box for integrated installation of a super-power variable frequency power supply. Background technique [0002] The traditional high-power and high-voltage variable-frequency power supply devices are composed of several discrete components, each of which is an independent cabinet. It is acceptable for fixed installation indoors, but it is not suitable for on-site use. Because the cabinets with scattered components do not have the functions of outdoor storage and centralized storage and transportation, they are not suitable for the use requirements of mobile ultra-high-power variable frequency power supplies, and complex internal assembly connections are required for on-site tests, which not only require professional technicians (non-users) After completion, the disassembly, assembly and electrical connection need to be repeated for each displacement, and the work efficiency is low.
