Abstract

The invention discloses a high voltage power distribution cabinet with good shielding performance. An electromagnetic shielding cover body is attached to the surface of the cabinet body of the high voltage power distribution cabinet. The cover body has a sandwich structure, and particularly, a layer of foam aluminum-copper-nickel alloy is clamped between two layers of permalloy plates. Electromagnetic waves in a low frequency band and a high frequency band can be well shielded, electromagnetic radiation of the high voltage power distribution cabinet can be prevented from polluting the environment, and interference of external electromagnetic waves on electrical equipment inside the power distribution cabinet can be reduced; and further, after the surface of the permalloy plate of the cover body is subjected to hydrochloric acid treatment, a nanoplate super hydrophobic structure is formed, self-cleaning, anti-fog, anti-freezing and anti-corrosion protection roles can be played, and the service life of the high voltage power distribution cabinet can be prolonged.

Description

technical field [0001] The invention belongs to the field of power distribution cabinets, and more specifically relates to a high-voltage power distribution cabinet with good shielding performance. Background technique [0002] In our living environment, various electrical appliances such as TVs, microwave ovens, induction cookers, computers, mobile phones, etc. will generate electromagnetic waves, and electromagnetic waves emitted by radio stations, TV stations, satellite communications, etc., all exist in our living environment. While enjoying a convenient life, we are also living with electromagnetic waves day and night, coexisting peacefully. However, with the development of modern technology, the impact of electromagnetic radiation on the environment is increasing. On the one hand, electromagnetic radiation will affect people's health and cause serious interference to the surrounding electronic equipment. On the other hand, electromagnetic radiation will Disclosure of ...
