800kV直流输电线路耐张绝缘子串整体更换方案设计及应用

摘要

It is very difficult to examine and repair the large tonnage, super long strain insulator string of 800 Kv direct current transmission lines; so according to the characteristics and the parameters of the strain insulator string, this thesis has carried out the research on the overhaul scheme of the whole strain insulator string; and the scheme is carried out in the actual operation exercises; also it is achieved the good practical effect, so as to offer for reference.%±800 kV特高压直流输电线路大吨位、超串长的耐张绝缘子串检修更换十分困难,因此针对特高压直流线路耐张绝缘子串的特点及参数,围绕特高压直流输电线路耐张绝缘子串整串更换进行了相关方案研究,并依照检修方案进行了现场实际操作演练,取得了良好的实用效果,供借鉴.
