In wet weather conditions, dirty insulators are prone to flashover discharge, so they must be cleaned and restored to the original insulation level. The general area is cleaned once a year, and the dirty area is cleaned twice a year (before the fog season).
1, power off cleaning
Power-off cleaning is to wipe the worker's pole with a rag after the line is cut off. If it is not clean, wipe it with a damp cloth or with a detergent. If it is not clean, replace the insulator or replace the composite insulator.
2, no power off cleaning
Generally, the insulating rod with a brush or cotton yarn is used to wipe the insulator on the running line. The electrical performance and effective length of the insulating rod used, and the distance between the person and the charged part should meet the requirements of the corresponding voltage level. There must be someone to supervise.
3, charged water rinse
Two methods, Dashui Chong and Xiaoshui Chong, the flushing water, the effective length of the operating rod, and the distance between the person and the charging department must meet the requirements of the industry regulations.
