摘　　要：介绍了一种基于电流互感器(TA)原理取能高压侧电源的励磁电流调节方法,分析了感应取电器二次电流运行性能数据与示波图,结果表明通过采用多重有源泄放阵列,同时配合超级电容器储能和双重瞬态电压抑制,可为现场监测装置提供能瞬时供出大功率能量的安全电源。Introduction was made to a method of excitation current adjustment for power supply at high-voltage side base on TA principle energy extraction. Analysis was made to the secondary electrical current operation performance data and oscillograms of the inductive energy extraction device. The results show that by using the method of multiple active bleeder arrays, with the super capacitor energy storage and dual transient voltage suppression, the transient high-power energy safety power supply is provided for the monitoring device on site.
