Abstract

The present invention discloses an anti-electromagnetic interference variable frequency transformer control system. An electromagnetic shielding cover body covers the variable frequency transformer control system, the cover body is a sandwich structure, and the sandwich structure is that: a layer of foamed aluminum-copper-nickel alloy is arranged between two layers of permalloy plates, so that the cover body with the sandwich structure is able to shield low-frequency stage and high-frequency stage electromagnetic waves, prevent the environment from pollution caused by electromagnetic radiation of the variable frequency transformer control system and reduce the interference of external electromagnetic waves in the variable frequency transformer control system; and moreover, the surfaces of the permalloy plates of the cover body forms a nanosheet super-hydrophobic structure after being processed by hydrochloric acid, so that the self-cleaning, anti-fog, anti-icing and erosion-resisting protection effects are realized, and the service life of the variable frequency transformer control system is prolonged.

Description

technical field [0001] The invention belongs to the field of transformers, and more specifically relates to an anti-electromagnetic interference frequency conversion transformer control system. 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 info...
