Design of High Frequency Current Sensors in Complex Electromagnetic Environments
This paper analyzes the Roche coil in the complex electromagnetic environment of the interference mechanism,research and design of a strong anti-interference high-frequency current sensor,through the optimization of the design of the skeleton structure of the Roche coil,change the direction of the sensor coil wire miscellaneous wire,thus changing the coil winding uniformity and the return line of the alignment of the structure,so that the go line and back to the line surrounded by the equivalent area of large turns is almost the same,so as to achieve the purpose of eliminating the external magnetic interference.Purpose.Through the experiment,the output linearity and immunity of the sensor under different conditions are good,and it has high measurement accuracy,which ensures the reliability of the monitoring of high-frequency currents of faults/hidden dangers on the collector line,and it has a positive effect on the efficient operation and maintenance management of wind power generation.
