Ventilation filter screen assembly for power cabinet

Abstract

The invention relates to the technical field of a power cabinet and particularly relates to a ventilation filter screen assembly for the power cabinet. The assembly comprises the power cabinet body, wherein a refrigerating device is fixed above a back surface of the power cabinet body through a bolt, supporting columns are welded to outer walls of four corners of the bottom of the power cabinet body, moving wheels with brakes are installed on outer walls of bottom ends of the supporting columns through rotating frames, an opening is formed on a front surface of the power cabinet body, rotatinghinges are fixedly arranged on inner walls of two sides of the opening, and a cabinet door of a double-hinge structure is fixedly installed on the rotating hinges. The ventilation filter screen assembly is advantaged in that the cold air is continuously conveyed into the control cabinet, the effect of rapid heat dissipation of the control cabinet is achieved, automatic dust removal of a filter framework is achieved, the optimal dust removal effect is achieved in the time with the minimum influence on equipment, the reasonable dust removal duration can be set, equipment maintenance is more user-friendly and intelligent, and the filter cotton is easy to clean and replace.

Description

technical field [0001] The invention relates to the technical field of power cabinets, in particular to a ventilation filter assembly for a power cabinet. Background technique [0002] Since there are a lot of energy-consuming equipment in the electrical cabinet, the heat generated during its operation will affect the stable operation of the equipment and damage the equipment. Therefore, most of the electrical cabinets are equipped with forced convection air cooling devices to reduce the temperature inside the electrical cabinet and improve electrical performance. The operational stability of the equipment. As we all know, there are a lot of dust and impurities in the air, and the airflow generated by the fan can easily drive these impurities into the electrical cabinet, thereby affecting the operation of the equipment in the electrical cabinet, so it is necessary to filter the impurities contained in the air through a filter device . [0003] At present, the common filter...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a ventilation filter assembly for power cabinets to solve the problem that the ventilation filter assembly proposed in the background technology is too simple in structure, difficult to clean and replace the filter cotton, and difficult to disassemble and maintain. Complicated problems that greatly shorten the service life and replacement cycle of the filter device
