极寒条件下输电线路弧垂在线监测技术研究应用
Study and application of sag online monitoring technology on transmission line under severe cold conditions
摘要
Abstract
The current contact and non-contact sag sensing technologies are studied in this paper.Performances of three sag sensors in low temperatures are compared and the results show that laser ranging sag sensor has small measuring error especially in cold conditions.Based on the results,sag online monitoring system of transmission line under severe cold conditions is designed,which has applied in Hulun Buir,Hainal,and Manzhouli.From the comparison of monitoring results,the designed system in this paper has higher no fault rate than normal system,as well as no interrupt and packet loss,which indicates high stability and reliability.Results in this paper can offer clues to the design of online monitoring system under severe cold conditions to prevent and reduce transmission line accident,which has great social and economic effects.关键词
