摘　　要：简要综述了电子式电流互感器的发展,介绍了几种高压侧电路的供能方案并进行了对比。通过特制的电流互感器从母线感应能量,研制出一种用于高压侧电子电路的工作电源。探讨了在应用中可能会出现的一些问题。实验结果表明,该电源能在2倍额定电流下提供不小于 400mW的功率,基本能满足高压侧电子电路的功耗要求。The situation of electronic current transformer is summarized; and several power supply methods for high potential circuit are compared. The power is induced from line by means of a special CT. A power supply device is developed, some problems which may appear in practical application are discussed. The results showed that the circuit of power supplies can supply power about 400mW when the current change from 6A to 900A, it can satisfy the requirements of the high potential circuit power supply.
