Design of Inductive Power Taking System for Smart Grid Monitoring Equipment

Abstract Due to the continuous growth of urban electricity load and increasing development high-voltage transmission technology, effective operation online monitoring equipment line is particularly important, which also a necessary condition for smart grid. However, power supply conditions usage scenarios grid are limited. Conventional methods such as battery new energy generation have disadvantages cumbersome replacement, stability greatly affected by environment, so they difficult meet trend rapid capacity increase stable equipment. Aiming at technical bottleneck in supply, this paper proposes current transformer inductive taking method based on capacitive reactance matching shunt, using open air gap secondary winding set bus connect capacitor its excitation inductance series carry out impedance matching, then shunt through another branch with it both ends air-gap obtain electric energy. Through circuit model experiment power-taking system, verified that can more power.
