Noncontact electromagnetic passive cutting magnetic line power taking device and method

Abstract

The invention relates to a noncontact electromagnetic passive cutting magnetic line power taking device which is arranged on an unmanned aerial vehicle. The device comprises an antenna (1), a separation circuit (2), a transformer (3), a rectifying module (4) and a voltage stabilizing module (5) which are connected in turn. When the unmanned aerial vehicle flies near the ultrahigh voltage power transmission line, the antenna (1) generates induced voltage and electromotive force because of the effect of the magnetic field and the electric field in the power transmission line. The separation circuit (2) transmits the alternating current generated in the antenna (1) to the voltage stabilizing module (5) through the transformer (3) and the rectifying module (4) and directly transmits the directcurrent generated in the antenna (1) to the voltage stabilizing module (5). The voltage stabilizing module (5) outputs rated power for charging of the unmanned aerial vehicle. Compared with the devices in the prior art, the working power required for charging of the storage battery of the unmanned aerial vehicle can be stably obtained so that the effect is obvious, and the device is favorable forpopularization and application in the field of online monitoring of the power grid equipment and especially can enhance the high voltage line power transmission unmanned aerial vehicle inspection endurance capacity.

Description

technical field [0001] The invention relates to a wireless charging method, in particular to a non-contact electromagnetic type passive cutting magnetic induction line power-taking device and method. Background technique [0002] With the rapid development of the national economy, the power transmission capacity and transmission distance have increased rapidly, and large-capacity, long-distance transmission lines have been put into operation. The transmission voltage has also increased, and the requirements for line safety have become higher and higher. UHV transmission lines generally refer to transmission lines that carry the above voltages. [0003] In order to solve the threat to power grid security caused by frequent disasters in recent years, many domestic power companies have begun to use special unmanned helicopters to inspect high-voltage power lines. UAVs use batteries as built-in power sources. However, due to the limited power of batteries, UAVs cannot fly long ...
