The most prone to failure of electronic circuits is the power supply circuit,and DCS is no exception.A power failure will directly affect the normal operation of the DCS.Practice has proved that after the power module is used for a long time,the failure of electronic components leads to a high probability of failure of the power module.In addition,the faults of the power cord connection cannot be ignored,such as loose terminals,loose bolt connection points,and poor contact caused by corrosion.

电子电路最易出故障的是电源电路，对于DCS也不例外。电源发生故障，将直接影响DCS的正常工作。实践证明，电源模块使用时间长后，电子元器件失效导致电源模块发生故障的几率较高。此外，不能忽视电源线连接的故障，如接线头松动、螺栓连接点松动、锈蚀引起的接触不良故障。
