摘要

介绍了一种新型高压侧在线监测工作电源的解决方案:用高频磁芯线圈作为电能的发送端和接收端

利用一种绝缘磁性材料为高频磁场提供传输通路

通过高频电源发送电能

实现从低压侧向高压侧供能;利用有限元分析软件ANSYS对该方案的磁路进行了仿真

为该方案的可行性提供了依据;根据无接触功率传输技术的模型为该方案提出了优化策略;最后通过实验验证了该方案优化策略的正确性和有效性。该电源设计方案不同于以往从高压侧取能而易受高压线路影响的方案

而与从低压侧取能的激光供能相比

又具有经济性

从而为高压监测工作电源的解决提供了一个新的思路。

Abstract

A novel power supply scheme for high-voltage monitoring is proposed. Ferrite core coils are taken as the sending and receiving ends of electrical energy

an insulating magnetic material is used to provide a transmission path for high frequency magnetic field

thus power supply from low voltage side to high voltage side is realized via high-frequency power supply. Simulation of the magnetic circuit in the scheme is conducted by using the finite element analysis software ANSYS

and the results support the feasibility of the scheme. Moreover

an optimization strategy is proposed based on the model of non-contact power transfer technology for the scheme

and experiment verifies the correctness and effectiveness of the optimization strategy. The proposed power supply scheme is different from the existing method in which power is obtained from high voltage side thus may suffer unfavorable impact of high voltage transmission line

and it is economical compared with the laser energy supply method in which power is obtained from low voltage side. This study may provide a way to development of new power supply for high-voltage monitoring.
