在日常生活中，在使用矩形電連接器時(shi)，有時(shi)會出現電連接(jie)器過(guo)熱(re)，那么(me)這種情況是由什么(me)引起的呢？

 1.當發現有故障(zhang)跡象時，應(ying)拆(chai)下電(dian)(dian)(dian)(dian)(dian)源線電(dian)(dian)(dian)(dian)(dian)連(lian)接(jie)器(qi)，擰下電(dian)(dian)(dian)(dian)(dian)熱水器(qi)插(cha)座(zuo)中的導電(dian)(dian)(dian)(dian)(dian)柱(zhu)，用零號砂布或研磨膏(gao)打磨至明亮，去掉電(dian)(dian)(dian)(dian)(dian)源線與電(dian)(dian)(dian)(dian)(dian)連(lian)接(jie)器(qi)接(jie)觸(chu)舌片連(lian)接(jie)處的導線、接(jie)線螺(luo)絲、舌片和電(dian)(dian)(dian)(dian)(dian)熱水器(qi)上插(cha)座(zuo)內(nei)導電(dian)(dian)(dian)(dian)(dian)柱(zhu)的氧化層，降低接(jie)觸(chu)電(dian)(dian)(dian)(dian)(dian)阻(zu)。

 2.在電(dian)源線(xian)接頭片和電(dian)熱水器的插座導線(xian)柱上涂一點(dian)導電(dian)膏。

 3.電連接器上舌片、接線螺絲燒(shao)損嚴重，應立即更換。

 4.如果電(dian)熱水(shui)器上的(de)插座和導電(dian)柱燒壞嚴重，應立即拆(chai)下(xia)，更換相同規格(ge)的(de)插座和導電(dian)柱。安裝(zhuang)(zhuang)電(dian)熱水(shui)器插座時，應安裝(zhuang)(zhuang)電(dian)源閘刀(dao)開關。
