On-Line Monitoring Device and Protective Measures of Icing on Overhead Transmission Lines by Micro-Exploration

在电网的实际运行过程中,输电线路覆冰是常见的一种气象灾害,它会严重影响电路运行的安全性和稳定性。在我国输电线路发展中,覆冰发生的几率非常高,因而出现了绝缘子断裂、导线断线等事故,对电力系统的安全造成了很大的威胁。所以,针对架空输电线路覆冰问题需要安装在线监测系统,对覆冰进行准确的检测,从而制定有效的防护措施,保证架空输电线路能够正确运行。论文针对架空输电线路覆冰问题展开讨论,分析覆冰在线检测装置,并提出架空输电线路覆冰的有效防护措施。

In the process of actual operation of power grid,icing of transmission lines is a common meteorological disaster,which will seriously affect the safety and stability of circuit operation.In the development of transmission lines in China,the probability of icing is very high,so there are accidents such as insulator fracture,wire disconnection and so on,which pose a great threat to the safety of power system.Therefore,in order to solve the problem of icing of overhead transmission lines,it is necessary to install on-line monitoring system to detect icing accurately,so as to formulate effective protective measures to ensure the correct operation of overhead transmission lines.This paper discusses the problem of icing of overhead transmission lines,analyzes the icing on-line monitoring device,and proposes effective protection measures for icing of overhead transmission lines.
