摘要:

针对贵州振华群英电器有限公司某型平衡力电磁继电器负载类型复杂、单一触点材料无法满足全工况使用的问题,开展触点材料选型试验研究。以银氧化镉(AgCdO)、银氧化锡氧化铟(AgSnO2In2O3)两种触点材料为对象,完成阻性交直流工况下的电寿命对比试验。根据不同负载特性匹配适配的触点材料方案,有效提升继电器整体使用寿命。实验结果可为同类电磁继电器的触点选材与产品研发提供试验依据与技术参考。

Abstract:

Aiming at the problem that a certain type of balanced-force electromagnetic relay produced by Guizhou Zhenhua Qunying Electric Appliance Co., Ltd. operates under complex load conditions, and a single contact material cannot meet the service requirements under all working conditions, experimental research on contact material selection is carried out. Taking two contact materials, silver-cadmium oxide (AgCdO) and silver-tin oxide-indium oxide (AgSnO2In2O3), as the research objects, comparative electrical life tests are completed under resistive AC and DC operating conditions. Matching appropriate contact material schemes according to different load characteristics can effectively extend the overall service life of the relay. The research results can provide experimental basis and technical reference for contact material selection and product development of similar electromagnetic relays.

Key words: electromagnetic relay, AgCdO, AgSnO2In2O3, contact materials, resistive life
