摘要
电触头是电器开关的重要组成部分,电触头的接触电阻不仅影响电器开关的电气性能,对电器产品的节能降耗也有重要意义。本文分析了商用电触头的表面异物、粗糙度、平坦度及表面膜对接触电阻的影响,指出了影响接触电阻的主要因素及改善途径。
The electrical contact is an important part in electrical switches. The contact resistance of electrical contacts will not only affect the electrical switches properties, but also play an important role in energy saving of electrical appliance. This paper analyzes the surface foreign materials, surface roughness, surface flatness, as well as the surface film of electrical contacts and their effects on contact resistance. The main technical indicators which affect contact resistance and the improving methods are also put forward.
