Abstract

The invention discloses an anti-electromagnetic interference type vacuum circuit breaker. A shield with an electromagnetic shielding function covers the vacuum circuit breaker body and is of a sandwich structure, and particularly, the sandwich structure is formed by sandwiching a foamed aluminum-copper-nickel alloy layer between two permalloy layers. The anti-electromagnetic interference type vacuum circuit breaker has the advantages that low-frequency-band and high-frequency-band electromagnetic waves can be well shielded, environmental pollution caused by electromagnetic radiation of the vacuum circuit breaker is prevented, and interference of external electromagnetic waves on the vacuum circuit breaker is weakened; further, the permalloy surface of the shield is subjected to hydrochloric acid treatment to form a nanosheet super-hydrophobic structure, so that self-cleaning, antifog, anti-freezing and anticorrosive protection effects are achieved, and service life of the vacuum circuit breaker can be prolonged.

Description

technical field [0001] The invention belongs to the field of circuit breakers, and more specifically relates to a vacuum circuit breaker resistant to electromagnetic interference. 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 th...
