摘　　要：在自动控制领域,常常会遇到强电设备的智能控制问题,其中如何利用低电压、小电流的可编程器件控制高电压、大电流的强电设备一直是控制界的重点和难点。电流变送器可以将交流电流变换为直流电流并转化为数字信号接驳PLC、单片机或PC机等控制器,从而轻松地完成生产设备的智能控制与监控任务。在此过程中电流变送器发挥着至关重要的作用。The problems of controlling to the devices working in high voltage usually appear in the field of autocontrolling. It ts importance and difficulty to control the devices working in high voltage and big current by programmable unit in low voltage and small current. Current transducer can change AC current into DC current and Into digital signal which can directly connect to PLC. SCM, PC etc, It is simple to finish controlling Work on it. Current transducer plays a very important role in the course. This Is an example of use of current transducer in automatic control system in pumping station.
