Device based on transmission line step voltage acquires electric energy

The utility model relates to a transmission line gets electric field, and more specifically relates to a device based on transmission line step voltage acquires electric energy. The utility model discloses a device based on transmission line step voltage acquires electric energy includes rear -end device, headend equipment and high conductivity insulated wire, moves ahead with the drive of secondgyro wheel through the first gyro wheel of central control module control and realizes that transmission line patrols and examines the equipment inspection task of moving ahead to control step voltagegathers the A end and step voltage gathers the voltage between the B end, when the device that acquires the electric energy is in initial condition or other unoperated state, by the storage battery power supply, when the device that acquires the electric energy was in operating condition, step voltage gathered A end and step voltage and gathers the coordinated control of voltage through central control module and high -ga
