The input end of the energy storage device 10 is also connected to a voltage stabilizing circuit, and the other end of the power cable 9 transmits electrical energy to the energy storage device 10 for storage via the voltage stabilizing circuit.

[0025] Specifically, the present invention has a novel structure and ingenious design. By arranging multiple coil plates 4 with embedded coils at intervals along the length direction of the insulator body 1, a distributed magnetic resonance coupling path is formed to achieve contactless energy transmission from the high-voltage side to the low-voltage side, while maintaining the mechanical support and electrical isolation functions of traditional insulators. The present invention integrates the insulator function with wireless energy transmission technology to provide reliable power supply for line monitoring devices (such as cameras, sensors, and inspection drones), solving the problems of frequent battery replacement, power supply stability affected by weather, or limited power supply power faced by traditional technologies using batteries, solar energy, or wind power generation devices.
