重庆升降平台在作业过程中遇到故障时应当掌握一定的判断和检修能力，例如电线及调压阀发热，细心的用户会发现引起发热的原因是不一样的，下面就给大家详细介绍一下电线过热的原因有哪些？

1、绝缘套管使用不到位，系统发生短路故障，过电流使容量不足的接点或有缺陷的接点，发生瞬间冒火等，接点发热主要是因为接触电阻变大造成的。

2、接线盒没有及时使用，长期运行的铜铝接头，接触面没有镀银或没有挂锡的接头，因接触面产生严重电化腐蚀生成氧化膜，使接头处电阻增大，极容易成为发热点；平时流经小电流的接点，因系统突然变化，电流突增，导致接点发热，及时使用接线盒可以预防此类问题的发生。
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、电线接头处不使用绞接方法而是采用违章的弯钩状连接方法。
