Abstract With the continuous development of China's power system, the user's demand for electricity is higher and higher. As the terminal of power system, the distribution network must ensure its stable and reliable operation. In order to realize the maintenance of 10kV distribution network lines without power cut and meet the requirements of live working under various complicated conditions, this paper proposes a live working robot which can quickly replace the working arm, introduces its overall structure design, and describes the overall insulation equipment of the live working robot in detail, including insulating bucket, wireless transmission platform and working arm. In order to verify the insulation performance of the robot arm, a 10kV distribution network line model is established by using ATP-EMTP simulation software. The voltage and leakage current of the live working robot with and without insulation section are simulated and calculated under the normal operation of the line. The results show that the voltage and leakage current on the working arm will cause danger to the safety of operators when the insulation section is not added; the voltage on the working arm is 0.4μV and the leakage current is 0.4μA after adding 1cm nylon material, which is far less than the safety limit of live working.
