Problems solved by technology

[0002] Shutters will be set on the shell of the electrical cabinet to solve the problems of heat dissipation and air circulation. Due to the particularity of the electrical cabinet, the electrical components in it will generate useless electromagnetic radiation interference during use. Although the ventilation requirements are met, the The normal and safe operation of other external equipment has an impact that cannot be ignored, so electromagnetic radiation needs to be shielded at the shutters to minimize the impact of electromagnetic radiation

Abstract

The invention discloses a shielding ventilating window. The shielding ventilating window comprises a shutter on a box shell. A cellular shielding ventilating window is arranged at a position corresponding to the shutter in an inner side of the box shell. A shielding window periphery is welded on the box shell through a stainless steel plate. In the invention, a ventilation requirement of a electric appliance cabinet can be satisfied and simultaneously the shielding window is arranged behind the shutter, and seal treatment is performed to a connection part of the shielding window and the box shell. Interference of electromagnetic radiation to other external equipment through the shutter can be shielded. The electromagnetic radiation can be eliminated as much as possible and influence is reduced.

Description

technical field [0001] The invention relates to a ventilation window, in particular to a ventilation window capable of shielding electromagnetic interference. Background technique [0002] Shutters will be set on the shell of the electrical cabinet to solve the problems of heat dissipation and air circulation. Due to the particularity of the electrical cabinet, the electrical components in it will generate useless electromagnetic radiation interference during use. Although the ventilation requirements are met, the The normal and safe operation of other external equipment has an impact that cannot be ignored, so electromagnetic radiation needs to be shielded at the shutters to minimize the impact of electromagnetic radiation. Contents of the invention [0003] Purpose of the invention: In view of the above problems, the purpose of the present invention is to provide a shielding ventilation window for electrical cabinets, which can shield the interference of electromagnetic ...
