Abstract

An electric field overhead line wireless energy taking device relates to a wireless power taking device in the technical field of power transmission. The problem that the power supply mode of an existing online device installed in a high-voltage environment is complex and low-voltage energy cannot be taken directly from an overhead conductor is solved. The electric field overhead line wireless energy taking device comprises a receiving line and a power collecting part. The receiving line is disposed between an overhead ground line and an overhead conductor, and the receiving line is fixed below the overhead ground line. The receiving line is rod-shaped, one end of the receiving line is bent towards the overhead ground line, and the other end of the receiving line is connected with the power input end of the power collecting part through an insulated conductor. Power output from the power output end of the power collecting part is supplied to electrical equipment. The surface of the power collecting part is connected with the ground. The electric field overhead line wireless energy taking device of the invention is mainly applied to high-voltage lines.

Description

technical field [0001] The invention relates to a wireless power-taking device in the technical field of power transmission. Background technique [0002] With the promotion of smart grid technology and condition-based maintenance technology, in addition to traditional power equipment, more information collection, transmission and processing devices will be added to the future power grid. Power equipment condition monitoring devices installed in high-voltage environments (strong magnetic field, strong electric field radiation) have powerful detection, data processing and communication functions, but the development of their power supply methods is relatively lagging behind. Although many field devices are close to the grid, they cannot directly obtain power from the high-voltage grid due to the limitation of the voltage level. It is difficult to find a suitable power supply entry point or feeding method, which has caused great obstacles to the application of power equipment...
