The invention discloses an inductive energy-obtaining device, and the device comprises a housing. The interior of the housing is provided with an inductive energy-obtaining module and a circuit board. The inductive energy-obtaining module comprises an energy-obtaining iron core, an energy-obtaining coil, and a compensation coil. The energy-obtaining coil sleeves a bus of a power distribution cabinet, and the energy-obtaining coil and the compensation coil are disposed on the energy-obtaining iron core in a winding manner. The circuit board is provided with a control module, an overvoltage protection module, a rectification filtering module, a DC-DC module and a voltage-stabilizing module, wherein the overvoltage protection module, the rectification filtering module, the DC-DC module and the voltage-stabilizing module are sequentially connected with the control module. The overvoltage protection module is connected with the inductive energy-obtaining module. The housing is also provided with a through hole for the passing of the bus of the power distribution cabinet. The device can change the connection mode of the energy-obtaining coil and the compensation coil through the control module, enables the inductive energy-obtaining module to be in different energy-obtaining modes, can inhibit the change of magnetic flux, can effectively inhibit the saturation of the energy-obtaining iron core, stabilizes the voltage rectified by the rectification filtering module, and solves a problem that the fluctuation range of a primary side current is large.
