Relay, which is one of the most common components in the modern industry, is widely used in the power, lighting and safety systems of the space, industry, coal-mining and electric application and plays an significant role in ensuring the normal and safe working of the industry equipments.So the reliability of the relay reveals to be particularly important.As a statistical result, most of the relays failures are due to the excess erosion induced by surge stress impacting the contacts.This article describes a novel method of protection circuit for relays arc-suppression based on system actually practice, and takes a positive effect on improving the reliability of the relay.
