Electronic control cabinet with electromagnetic shielding function

Abstract

The invention provides an electric control cabinet with electromagnetic shielding function. The inner shell, the inner wall of the inner shell is provided with a copper wire mesh, the top of the cabinet is connected with a moisture absorber, the moisture absorber is equipped with a color-changing desiccant, the surface of the moisture absorber is equipped with an observation window, and one side of the cabinet is also connected with a Micro positive pressure device, the top of the micro positive pressure device on the cabinet is provided with an air outlet. The electric control cabinet provided by the invention can well isolate and absorb the electromagnetic waves generated by its internal power components, which can not only improve the surrounding environment, but also reduce the interference of electromagnetic waves on the power components themselves; The device can not only ensure that the power components in the electric control cabinet do not contact the corrosive gas outside the cabinet, but also reduce the temperature inside the cabinet.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to an electric control cabinet with electromagnetic shielding function. Background technique [0002] The electric control cabinet is a commonly used power infrastructure. It is equipped with a large number of power components and connected to AC power. Therefore, the electric control cabinet will generate a large amount of electromagnetic radiation when it is working. On the one hand, this electromagnetic radiation will cause damage to the outside world. On the other hand, after it is reflected on the inner wall of the cabinet, it will cause interference to the power components themselves. However, the existing electric control cabinets are generally made of a layer of iron sheet, which cannot produce a good shielding effect on electromagnetic waves; and when the working environment of the electric control cabinet is relatively poor, such as when there is a large amount of corrosi...

[0002] The electric control cabinet is a commonly used power infrastructure. It is equipped with a large number of power components and connected to AC power. Therefore, the electric control cabinet will generate a large amount of electromagnetic radiation when it is working. On the one hand, this electromagnetic radiation will cause damage to the outside world. Hazard, on the other hand, after it is reflected on the inner wall of the cabinet, it will cause interference to the power components themselves

However, the existing electric control cabinets are generally made of a layer of iron sheet, which cannot produce a good shielding effect on electromagnetic waves; and when the working environment of the electric control cabinet is relatively poor, such as when there is a large amount of corrosive gas around, these corrosive gases Entering the inside of the cabinet will damage the power components and shorten the service life of the electric control cabinet
