The invention relates to a novel magnetic core structure for improving electromagnetic coupling efficiency of a buoy underwater power supply system. Two magnetic core structures are butt-joint in use, an upper part magnetic butt-joint end is fabricated at the upper part of one end of a magnetic core structure, a lower part magnetic butt-joint end is fabricated at the lower part of the other end of the magnetic core structure, the two magnetic core structures are oppositely embedded and matched, and a magnetic force is formed between a transverse end face and a longitudinal end face between the oppositely matched upper part magnetic butt-joint end and lower part magnetic butt-joint end. According to the novel magnetic core structure for improving electromagnetic coupling efficiency of the buoy underwater power supply system, the influence of the existing structure hollow air gap to an electromagnetic coupler is eliminated, relative magnetic permeability is improved, and electromagnetic coupling efficiency is improved, so that the electric energy conversion efficiency of the buoy underwater power supply system is largely improved, more detection instruments associated with the buoy underwater power supply system can be mounted, and hydrogeology detection is more various.
Description
technical field [0001] The invention belongs to the field of energy saving, in particular to a magnetic core structure for improving the electromagnetic coupling efficiency of a buoy underwater power supply system. Background technique [0002] The ocean buoy is an important part of the ocean monitoring system, and the power supply problem is the key to whether the ocean buoy system can realize real-time monitoring of the marine environment. Contact Power Transfer Systems. The system separates the steel cable used to fix the ocean buoy from the cable used to transmit electrical energy, and uses a cable ring parallel to the steel cable for electrical energy transmission. The electromagnetic coupler, the core component of the power transmission system, mainly chooses the U-shaped ferrite magnetic docking method. The experiment shows that the transmission efficiency of the system is about 57%, which can basically realize the low-power transmission of non-contact electric energ...
