Research and application of the Water Washing Robot with hot-line working used in 220kV open type substation

Abstract

220kV open type substation equipment's surface will readily accumulate industrial and natural filthy when they expose to outdoors in a long-term, and this situation will lead to the phenomenon of flashover. The Substation Water Washing Robot in this paper can transport the high pressure water jet equipment to the operating position by insulated telescopic boom, and then carry out water washing operation to substation insulators, surge arresters, electric equipment casing and others with the high purity water through RO reverse osmosis technology. Robot can achieve a barrier-free travel in the area of substation outdoor road and grass or gravel road in the facilities religion with crawler mobile chassis; Using multistage combination insulation and insulated telescopic lifting arm structure to improve the stability of water flushing operation; Using wireless remote control to effectively reduce the intensity of manual work, improving the safety of operation and ensuring the operation safety.
