Description

直插式铜铝连接器
技术领域
本发明涉及一种直插式铜铝连接器,可以代替MC4进行使用。
背景技术
线缆的特殊部位常常需要对外界的尘土、水、空气等隔绝,如线缆的连接部位。例如,光伏线路部分改为铝或铝合金导体电缆时,就涉及铜与铝连接,要解决铜铝间的电化学腐蚀问题,就要做好密封。否则可能造成连接失效,影响光伏线路安全稳定运行。良好的连接,其接触电阻略高于初始值;而劣质的连接,其接触电阻可能达到几十甚至几百倍的初始值。一个连接头上消耗的功率,抵得上一整根电缆线消耗的功率。接触电阻大,使得发热更严重,这是一个恶性循环。不但造成电力能源无谓消耗,长久使用还会引起电气线路断线或电气火灾。
