     摘 要:接续金具在正常工作时,通常要求电接触处的接触电阻小而稳定。从导电斑点、接触电阻模型、表面膜、热效应和测量方法等方面总结了接触电阻的研究现状,并提出配网接续工作中减小接续金具与导线之间接触电阻的有效措施。指出在设计和安装电力金具时,有必要形成相关的性能测试和安装工艺规范。

    Abstract: When the contact fittings are in normal operation, the contact resistances must maintain reliable and favorable electrical contact effects.The research status of contact resistance was summarized from the aspects of conductive spots, contact resistance model, surface film, heat effect andmeasuring methods etc. This paper proposed the effective measures to reduce the contact resistance between the contact fitting and the conductor in the work of distribution network connection. It is pointed out that when to design and install the electric power fittings, it is necessary to form the relevant performance test and installation technology specification.
    Key words: contact fitting; contact resistance; influencing factor; material
