Background

The transformer substation is a hub of a power transmission network, the safety of the running state of equipment of the transformer substation is very important, and effective inspection of the equipment is an important guarantee for ensuring good running of the transformer substation and power supply reliability of a large number of users. With the development of the electric power robot technology, the robot inspection gradually replaces manual inspection, and the labor intensity is greatly reduced.

For a long time, the routing inspection work of the indoor equipment of the transformer substation is mostly carried out in a manual mode, and the traditional manual routing inspection mode has the defects of high labor intensity, low working efficiency, dispersed detection quality, single means and the like, and cannot accurately and timely transmit data detected manually to a management information system afterwards. Along with the popularization of the unattended mode transformer substation, the inspection workload of the transformer substation is increased, and the inspection arrival rate and timeliness cannot be guaranteed. Especially after special geographical conditions such as plateau, gobi or extreme weather such as strong wind, fog day, ice and snow, hail, thunderstorm take place, cause the manual work and can't patrol and examine in time to there is great safety risk in patrolling and examining by the condition restriction, in case transformer substation accident takes place, decision maker is because of can't in time obtain audio-visual field information, often can the mistaking opportunity of best processing accident, causes the important accident such as unnecessary economic loss or even casualties.

Due to the limitation of working environment, the traditional transformer substation inspection robot has poor trafficability and cannot adapt to different pavements, and the use is greatly limited.
