Title:
SYSTEM AND METHOD FOR DYNAMICALLY ADJUSTING COUPLING COEFFICIENT OF NON-CONTACT TRANSMISSION MAGNETIC MECHANISM
Document Type and Number:
WIPO Patent Application WO/2021/238901
Kind Code:
A1
Abstract:
The present invention relates to the technical field of oil drilling, and in particular, to a system and a method for dynamically adjusting a coupling coefficient of a non-contact transmission magnetic mechanism. A power supply end is connected to a non-contact transmission electric energy conversion module and a magnetic field regulation electric energy conversion module respectively by means of an input power consumption measurement unit, the non-contact transmission electric energy conversion module is connected to a transmitting coil by means of a tuning wave-blocking circuit, a receiving coil is provided corresponding to the transmitting coil, the receiving coil is provided on the wave-blocking circuit, the wave-blocking circuit is connected to a load end by means of a rectifying and voltage stabilizing circuit and an output power consumption measurement module, signal loading and extraction modules having a controller and a signal modulation and demodulation module are connected in parallel to two ends of the transmitting coil and the receiving coil, and the magnetic field regulation electric energy conversion module is also connected to a compensation coil by means of a wave-blocking circuit.
