摘要
针对用于工业现场的计算机实时控制系统抗干扰问题,本文介绍了采用1:1隔离变压器抑制干扰的方法,并做了理论分析。实际应用表明,这种隔离变压器具有较好的滤波作用。
For restraining disturbance from power supply inthe site of control with the computer, the isolating transformeris used and its character is analysed in this paper. Accordingto the application, it is showed that the filter result of theisolating transformer is better.
