Abstract

The invention discloses an inductive power-obtaining device of a high-voltage line robot and a working method of the inductive power-obtaining device. The device comprises a relay and a rectifier bridge circuit which are sequentially connected at two ends of a secondary coil of a power-obtaining transformer in series, wherein the rectifier bridge circuit is connected with a storage battery and a voltage stabilizer respectively, the relay is connected with a control circuit, the storage battery is connected with a current detection circuit, and the current detection circuit is connected with the control circuit in series; contacts of the relay divide the secondary coil of the power-obtaining transformer into two parts with different numbers of turns and controlled by the control circuit to be opened and closed, so that the turn ratio of the power-obtaining transformer is switched. The device has the benefits as follows: the turn ratio of the power-obtaining transformer is switched through the control circuit, and the output voltage and current are effectively regulated.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a high-voltage line robot wide-current induction power-taking device and a working method thereof. Background technique [0002] High-voltage transmission lines are mostly in the form of overhead, across uninhabited mountains, rivers, etc., which brings great difficulties to the maintenance of high-voltage lines. At present, the maintenance work of high-voltage transmission lines mostly adopts the method of manual maintenance. There are many deficiencies in this overhaul method: [0003] 1. During maintenance, high-voltage lines must be powered off, which will have a great impact on social and economic benefits. [0004] 2. Maintenance personnel work at heights, and a little carelessness may endanger personal safety. [0005] 3. The work intensity of maintenance personnel is high. [0006] Using a robot with a high degree of automation for high-voltage line maintena...
