Non-contact induction charging device

Abstract

The invention provides a non-contact induction charging device comprising a current transformer, a bidirectional triode thyristor, an overvoltage protection circuit, a rectifying circuit, a BUCK circuit, a lithium battery pack, a voltage feedback control circuit and a voltage current feedback circuit, wherein a circular ring is formed by two C-shaped iron cores of the current transformer and is sleeved on a transmission line; the output end of the current transformer is connected with a relay matrix and is used for controlling the number of turns of a primary coil of the current transformer; an output of the relay matrix is connected with the bidirectional triode thyristor and is connected with the voltage feedback control circuit and the voltage current feedback circuit at the same time; the output end of the rectifying circuit is connected with the bidirectional triode thyristor through a voltage feedback control signal; and an input of the BUCK circuit is the output of the rectifying circuit and the output of the BUCK circuit is directly connected with the lithium battery pack; and the lithium battery pack is connected with the BUCK circuit through a voltage and current feedback circuit. According to the invention, when the device is used for charging a robot battery, the frequent online and offline are avoided, so that the practical applicability of the robot can be enhanced and the inspection frequency of the transmission line is improved.

Description

technical field [0001] The invention belongs to the technical field of automation and industrial robots, and in particular relates to a non-contact induction power-taking device. The non-contact induction power-taking device is used for the power supply of the high-voltage transmission line inspection robot, prolongs the on-site operation time of the robot, and is suitable for the high-voltage transmission line inspection robot below 500KV. Background technique [0002] The high-voltage transmission line inspection robot works on the high-voltage transmission line, and uses the detection equipment loaded by the robot to conduct fault inspections on the transmission line and related facilities. [0003] Due to the volume and weight of the robot itself, the design of the mechanism, etc., the operation process of going online and offline is very complicated, requiring the cooperation of multiple people on the line, and the collaborative operation is completed under the command ...
