     摘 要:接續(xù)金具在正常工作時(shí),通常要求電接觸處的接觸電阻小而穩(wěn)定。從導(dǎo)電斑點(diǎn)、接觸電阻模型、表面膜、熱效應(yīng)和測(cè)量方法等方面總結(jié)了接觸電阻的研究現(xiàn)狀,并提出配網(wǎng)接續(xù)工作中減小接續(xù)金具與導(dǎo)線之間接觸電阻的有效措施。指出在設(shè)計(jì)和安裝電力金具時(shí),有必要形成相關(guān)的性能測(cè)試和安裝工藝規(guī)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
