摘要
针对电子式电压互感器上一次和二次隔离的问题,笔者通过使用运算放大器、光电隔离放大器和其他一些分立元件,研究设计了一种光电隔离电路,很好地解决了该问题。仿真实验表明,这种隔离电路性能很好,有很大的实用价值。
To the issues of the isolation between the primary side and the second side of the electronic voltage transformer, a new photoelectric isolation circuit was designed to separate secondary circuit components from high voltage part effectively by using integrated operation amplifier and some other separate components. Simulation and experiments indicate that this circuit has good characteristics and is worth promoting.
