重慶升降平臺(tái)在作業(yè)過(guò)程中遇到故障時(shí)應(yīng)當(dāng)掌握一定的判斷和檢修能力，例如電線(xiàn)及調(diào)壓閥發(fā)熱，細(xì)心的用戶(hù)會(huì)發(fā)現(xiàn)引起發(fā)熱的原因是不一樣的，下面就給大家詳細(xì)介紹一下電線(xiàn)過(guò)熱的原因有哪些？

1、絕緣套管使用不到位，系統(tǒng)發(fā)生短路故障，過(guò)電流使容量不足的接點(diǎn)或有缺陷的接點(diǎn)，發(fā)生瞬間冒火等，接點(diǎn)發(fā)熱主要是因?yàn)榻佑|電阻變大造成的。

2、接線(xiàn)盒沒(méi)有及時(shí)使用，長(zhǎng)期運(yùn)行的銅鋁接頭，接觸面沒(méi)有鍍銀或沒(méi)有掛錫的接頭，因接觸面產(chǎn)生嚴(yán)重電化腐蝕生成氧化膜，使接頭處電阻增大，極容易成為發(fā)熱點(diǎn)；平時(shí)流經(jīng)小電流的接點(diǎn)，因系統(tǒng)突然變化，電流突增，導(dǎo)致接點(diǎn)發(fā)熱，及時(shí)使用接線(xiàn)盒可以預(yù)防此類(lèi)問(wèn)題的發(fā)生。
Hangzhou freight elevator did not use the junction box, aluminum joints, the contact surface is no long-running or no tin-silver-plated connector, due to exposure to severe galvanic corrosion surface oxide film, so that the joints resistance increases, very easy to become hot spots ; usually small current flows through the contact, due to a sudden change in the system, the current sudden increase, leading to joint fever, timely use of junction boxes can prevent such problems from occurring.

3、電線(xiàn)接頭處不使用絞接方法而是采用違章的彎鉤狀連接方法。
