With the popularization of live operation in national grid, the site situation is becoming more and more complicated. The application of intelligent robot in live operation can solve the problems of safety, high labor intensity, personnel gap and high cost. The electric robot in the distribution network is based on the upgrade of the existing electric robot products in the distribution network and the optimization in terms of functions: 1. The scheme has greatly optimized and improved the volume and weight of the whole machine on the existing scheme. 2, the whole machine operation table layout is more compact, the whole table function distinction is obvious, easy to operate and maintain, greatly improve the working range and efficiency. 3, the use of maintenance area is more convenient and no shelter. 4. Increase the design of heat dissipation duct of the whole machine, adopting S-shaped duct design to make the air flow fully pass through the heat dissipation source and ensure the normal operation of the module. 5, the whole machine waterproof scheme, using the main support frame and control box design waterproof water tank control box interior.
