新型并沟线夹的设计及其在配网线路中的应用

Design of new type parallel groove clamp and the application in transmission line of distribution network

针对配网主干线与用户引流线截面差别较大而导致接续点严重发热的问题,深入分析了接触电阻增大的原因,设计出一种全包裹结构全压接形式的新型并沟线夹,并在配网线路中应用。应用结果表明:新型并沟线夹具有良好的电气特性,解决了不同截面导线的接续问题,为电力行业解决异径导线接续问题提供了新的途径。

Aiming at the problem of a greater difference of section in main line and user download line caused the connection point serious heat,deeply analyzes the cause of contact resistance increase,designs a new type parallel groove clamp with full packaged structure and whole pressing contact form,and applies in distribution line. The application result shows that new type parallel groove clamp has better electrical characteristic,solves the problem of different section conductors to connect,provides a new way for solving the different section conductors connection problem of power sector.
