Abstract

The invention provides wireless power transmission equipment. The wireless power transmission equipment comprises a transmitting terminal and a receiving terminal, wherein the transmitting terminal comprises a high-frequency inverting circuit, a first LC oscillating circuit and a frequency self-adaptive tuning circuit; the frequency self-adaptive tuning circuit collects the coil current of the first LC oscillating circuit, controls the inverting frequency of the high-frequency inverting circuit through self-exciting oscillation and iterative methods, and ensures that the frequency of high-frequency alternating current always keeps fixed oscillation frequency of the first LC oscillating circuit; the receiving terminal comprises a second LC oscillating circuit, a rectifying and filtering circuit and a capacitance self-adaptive tuning circuit; the second LC oscillating circuit and the first LC oscillating circuit produce resonance; the capacitance self-adaptive tuning circuit collects the coil current of the second LC oscillating circuit, adjusts the capacitance of the second LC oscillating circuit through a direct current motor, and ensures that the coil current of the second LC oscillating circuit is the maximum. The wireless power transmission equipment solves the problem of the power supply reliability of a high-voltage transmission line video monitoring system in severe natural environment.

Description

technical field [0001] The invention relates to the technical field of inductive power acquisition and wireless power transmission for high-voltage transmission lines, in particular to a wireless power transmission device and a tuning method for supplying power to a high-voltage transmission line monitoring system. Background technique [0002] The monitoring of high-voltage transmission lines is related to the safety of the power grid and the stability of the power system. Since high-voltage transmission lines are usually located in uninhabited areas in the wild, it is inconvenient to adopt manual line inspection methods, so video surveillance is often used. The power supply reliability of the video surveillance system is related to the safety of the entire high-voltage transmission network, so it is necessary to study a way to provide long-term stable power supply. At present, domestic companies are mainly engaged in the production of solar and wind power generation equip...
