摘　　要：在比较严酷的环境当中,通常会对密封型继电器进行使用,但是如果继电器是由银金属氧化物材料制作而成的,继电器长时间处于密封条件下,对电寿命会造成严重影响,因此不能满足应用的实际需求。在这篇文章中,主要从继电器温度升高、电弧能量以及电寿命实验之后所接触的材料等方面,实现对触点材料的选择,并且在进行具体实验中后可以发现,如果使用非银金属氧化物来代替银金属氧化物来作为继电器的触点材料,可以将继电器电寿命有效提升上去。In relatively harsh environments, sealed relays are usually used, but if the relay is made of silver metal oxide material, the relay is in a sealed condition for a long time, which will seriously affect the electrical life, so Can not meet the actual needs of the application. In this article, the selection of contact materials is mainly realized from the increase of relay temperature, arc energy, and materials contacted after the electrical life test, and it can be found after conducting specific experiments that if non-silver metals are used Oxide instead of silver metal oxide as the contact material of the relay can effectively improve the electrical life of the relay.
