Abstract

The invention discloses an electromagnetic-interference-resistant transformer. An electromagnetic shielding cover covers the outside of the transformer and is of sandwich structure, specifically, an aluminum-cooper-nickel alloy layer is sandwiched between two permalloy plates. Electromagnetic waves in low frequency range and high frequency range can be shielded well, environment pollution caused by electromagnetic radiation of the transformer is prevented, and interference to the transformer by outside electromagnetic waves is reduced; further, a super-hydrophobic structure of nano sheets is formed on the surface of each permalloy plate of the cover through hydrochloric acid treatment, so that self-cleaning, fog-proof, freezing-proof and corrosion-resistant protecting effect is realized, and service life of the transformer can be prolonged.

Description

technical field [0001] The invention belongs to the field of transformers, and more specifically relates to an anti-electromagnetic interference transformer. 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 information, so that computers and other...
