水厂自动化捏制一般由计算机,可编程控制器PLC组成的集数据采集,过程控制和信息传送于一体的监控网络。由于这些设备大量采用高度集成化的CMOS电路组成,其对瞬间过电压的承受能力大幅降低,成为水厂受雷电损害的主要设备。 Automatic factory automation water by the computer, programmable logic controller PLC consisting of data collection, process control and information transmission in one of the monitoring network. Due to the large number of highly integrated CMOS circuits used in these devices, their ability to withstand instantaneous overvoltages has drastically reduced, making them the main plant damaged by lightning.
