Research on Safe Operation Technology of Insulated Short Stick for Live-working on Distribution Network

In view of the safety risks of personnel and tools in the insulation short stick method for live-working on distribution network, this paper analyzes the minimum safety distance requirements under different conditions by using insulation coordination idiom combined with operation mode, and analyzes the electromagnetic compatibility risk and protection requirements faced by electric tools in uninterrupted operation by using simulation calculation and simulation experiment. The minimum safety distance is 0.4m if the insulation shielding measures are taken in the insulation short stick method, and 0.9m if the insulation shielding measures are not taken. According to the characteristics of the disturbance source when the tool contacts the wire, the metal of the shell should be well connected, and the discharge air gap should be calculated between different metals with insulation isolation. Secondly, the external connecting cable must be shielded cable, and the in and out shell should be shielded.
