摘　　要：介绍了利用串行输出AD转换芯片MAX195的控制引脚实现电子式互感器转换信号从高压侧传送到低压侧的电子电路的设计原理和实验结果。研究结果表明:这种引导脉冲电路能可靠地实现高低压侧之间信号的传输,具有转换速度快、转换精度高的特点,对于电子式互感器的应用具有实际意义。This paper introduces design principle and experimental results of the electronic circuit which can realize the signal transmission from the high voltage side to low voltage side of the electronic transformer by using control pin of the MAX195 serial out A D conversion chip. Experimental results show this circuit can realize the signal transmission reliably with just one transmission line. And it can satisfy the demands about high-speed and high accuracy of analog-to-digital conversion in the signal processing of electronic electric-power transformers and it has important significance to the application of electronic transformer.
