On October 24, a robot carrying visible light and infrared cameras was inspecting the equipment inside the station according to a preset route in the equipment area of ​​the 220 kV Gushan Substation in Fuzhou, Fujian Province. At the same time, the operator is in the control room through the robot back to the visible and infrared images of the equipment to determine the health status. It is reported that in the process of actively promoting the construction of smart grid, the State Grid Fuzhou Power Company actively carry out robot applications in unattended substations. At present, the company has successfully researched and developed the operation robot for substation inspection robot and KYN switchgear in substation, and put it into operation at 110 kV Rendezvous, 110 kV MICE and 220 kV Gushan in Fuzhou. Application of robots instead of manual substation equipment inspection and operation, can give full play to the technical advantages, reduce the number of operation and maintenance personnel to effectively reduce the safety risk, greatly improve the centralized control of the rapid response capability, faster advance unmanned substation process .
