Water washing is one of key measures against pollution flashover in high voltage substation equipment. And the hot washing is a convenient and efficient way for substation equipment

which washes thoroughly

high efficiency and high economic benefit. In allusion to the problems and security risks existing in the artificial washing way

a hot washing robot system for high voltage substation equipment based on man-machine interaction and local intelligent control is designed

which mainly includes crawler type washing robot

high pressure pure water preparation device

and easy operation of hand-held terminal. In order to ensure the security

stability

flexibility of the system and meet the requirements of substation complex environment and hot washing task

a hierarchical control system of washing robot is presented. Then an effective washing way and multiple security protection technologies are given. And live working safety

flexible operation

and other issues of domestic washing robot can be solved. The reliability

safety

and feasibility of hot washing robot system for high voltage substation equipment are verified by the substation site test

which can meet standard requirements of substation hot-line work.
