A series intermediate frequency power supply cabinet

Abstract

The invention discloses a series medium-frequency power cabinet. The series medium-frequency power cabinet comprises a power connection cabinet, a partition cabinet, a wire arrangement cabinet and a backup power cabinet, wherein a sliding plate is arranged at an inner side of the power connection cabinet, a unit cabinet cylinder is arranged at a middle part of the sliding plate, a unit cabinet door is arranged at a left side of the unit cabinet cylinder, a withdrawing door is arranged on a surface of the partition cabinet, the partition cabinet is arranged at an inner side of the unit cabinetcylinder, a branching disc is arranged at an inner side of the wire arrangement cabinet, the wire arrangement cabinet is arranged at a right side of the power connection cabinet, limitation strips arefixedly arranged at a left side and a right side of the backup power cabinet, and the backup power cabinet is arranged at a rear side of the wire arrangement cabinet. The series medium-frequency power cabinet employs a series multi-split design, an electric furnace control circuit can be arranged separately, a cable fault is convenient to timely check and process, one electric furnace is used forsmelting, one electric furnace is used for preserving heat, power between the power cabinets is arbitrarily allocated, one-time pouring of a large piece and continuous pouring of a small piece can beachieved, and the production efficiency of the electric furnace is improved.

Description

technical field [0001] The invention relates to the technical field of intermediate frequency power supply equipment, in particular to a series intermediate frequency power supply cabinet. Background technique [0002] The intermediate frequency power supply is a static frequency conversion device, which converts the three-phase power frequency power supply into a single-phase power supply. It has strong adaptability to various loads and a wide range of applications. It is mainly used in melting, heat preservation, sintering, welding, quenching, Tempering, diathermy, molten metal purification, heat treatment, pipe bending, and crystal growth, etc. However, the existing intermediate frequency power supply cabinet still has some deficiencies in its own structure. For example, when a power supply cabinet controls electric furnaces and other equipment for production, it will cause low efficiency in the production system of electric furnace equipment due to the limitations of its...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a series intermediate frequency power supply cabinet to solve the problem that simply using one power supply cabinet for line connection in the above background technology will not only bring about low production efficiency of electric furnace equipment, but also make line connection relatively difficult. Trouble, when the circuit fails, it is not convenient to troubleshoot the circuit fault
