Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] Such as Figure 6 As shown, this embodiment provides a method for configuring long-distance wireless power transmission coils for high-voltage applications. Specifically, the transmitting coil and the receiving coil are respectively set at high potential and ground potential, and a high voltage is formed between the transmitting coil and the receiving coil. For electric field distribution, a relay coil is arranged between the transmitting coil and the receiving coil; the relay coil has a thin curved surface shape, and its curved surface shape is consistent with the equipotential surface distribution of the high-voltage electric field. That is, the coil windings are arranged along the equipotential plane. Since the relay coil conductor forms an equipotential body with potential floating, if its shape is consistent with the equipotential surface, ...

Abstract

The invention relates to a configuration method for long-distance wireless energy transmission coils applied in high-voltage occasions. The transmitting coil and the receiving coil are respectively set at high potential and ground potential, and a high-voltage electric field distribution is formed between the transmitting coil and the receiving coil, and the relay coil It is arranged between the transmitting coil and the receiving coil; the relay coil has a thin curved surface shape, and its curved surface shape is consistent with the equipotential surface distribution of the high voltage electric field. The invention has a simple structure and is easy to implement, and can not only improve the efficiency of wireless energy transmission, but also ensure the insulation between the high-voltage side and the low-voltage side.

Description

technical field [0001] The invention relates to the field of long-distance wireless power transmission, in particular to a method for configuring long-distance wireless power transmission coils in high-voltage applications. Background technique [0002] High-voltage transmission lines are the arteries of the power system, especially lines with a voltage level of 220kV and above. Therefore, it is necessary to protect high-voltage transmission lines in real time, and online monitoring is an indispensable link. High-voltage transmission lines are generally distributed in the wilderness, and there is no suitable low-voltage power supply to provide power for monitoring equipment. At present, solar panels or small wind generators are mainly used for power supply, but they are inevitably limited by natural conditions, and are costly and difficult to maintain. In order to solve the power supply problem of monitoring, long-distance wireless power transmission can be used to realize...
