Power supply structure for pole grounding device

The utility model provides a power supply structure for a pole grounding device. The power supply structure comprises a micro-control unit, a switching power supply module, a load information module and a feedback signal module, the micro-control unit is connected to the switching power supply module through two digital-to-analog converters, the output end of the switching power supply module is connected to the load information module, and the load information module is connected with the micro-control unit through the feedback signal module; the micro-control unit is used for adjusting output and outputting corresponding DACU and DACI according to a selected transmitting gear so as to control power output of the switching power supply module, the feedback signal module is used for transmitting load information of the load information module to the micro-control unit MCU for adjustment, and when the load changes, the output power of the power supply module is adjusted in time. The problem that the speed of s
