Abstract

The invention discloses a high voltage induction power obtaining device. The high voltage induction power obtaining device comprises a CT power obtaining coil, a rectification filtering circuit, a voltage stabilization circuit, an inverter, an isolating transformer and energy storage battery packs, wherein the CT power obtaining coil is arranged on a high voltage power transmission line in a sleeving manner; a secondary winding of the CT power obtaining coil is connected with the input end of the rectification filtering circuit; the output end of the rectification filtering circuit is connected with the input end of the voltage stabilization circuit; the output end of the voltage stabilization circuit is connected with the input end of the inverter; the output end of the inverter is connected with a primary coil of the isolating transformer; a secondary coil of the isolating transformer is connected with the input end of a rectifying circuit of the energy storage battery packs; a thirdalternating current is rectified into a third direct current by the rectifying circuit, and the third direct current is used for charging a first battery pack or a second battery pack in the energy storage battery packs; and the first battery pack and the second battery pack supply power for loads on the ground alternatively. The high voltage induction power obtaining device can uninterruptedly supply power for electrical equipment installed on the ground.

Description

technical field [0001] The invention relates to the field of high-voltage induction power-taking equipment, in particular to a high-voltage induction power-taking device. Background technique [0002] At present, high-voltage induction power-taking devices have been widely used in high-voltage transmission lines. The high-voltage induction power-taking device is a power-taking device that uses the electromagnetic energy induced around the high-voltage transmission line to obtain electric energy. The high-voltage induction power-taking device converts the electromagnetic energy around the high-voltage transmission line into electric energy, and provides working power for the on-line detection, monitoring, inspection, anti-theft and other electrical equipment installed on the high-voltage transmission line. [0003] In the prior art, the high-voltage induction power-taking device is generally composed of a CT power-taking coil, a rectification filter circuit and a voltage sta...
