There are also many problems in the power supply,such as the inability of the backup power supply to be switched on by itself,the unreasonable configuration of the insurance and the internal failure of the power supply causing the power supply to be interrupted,the fluctuation of the temperature and voltage power supply caused by the malfunction of the protection and the poor contact of the plug,resulting in no output of the temperature and pressure power supply;some The entire cabinet of the system supplies all input signals or a power supply with a large external load through one fuse,and the remaining control power supply is neither connected nor redundant

电源方面的问题也较多，如备用电源不能自投，保险配置不合理及电源内部故障等造成电源中断，温压电源波动引起保护误动及接插头接触不良导致温压电源无输出；有的系统整个机柜通过一路保险供所有输入信号或一路电源外接负载很大，还的控制电源既未接又未有冗余备用。
