电源是通信系统的关键设备之一,电源系统常见故障有一般性故障和紧急故障。一般性故障指不会影响通信安全的故障,包括交流防雷器雷击损坏、单个模块无输出、监控单元损坏等;紧急故障指影响通信安全的故障,包括交流输入与控制损坏而导致交流停电、直流采样和控制电路损坏而导致直流负载掉电等。如果不能及时对故障进行处理,将导致通信系统的瘫痪,带来严重的损失,因此,应充分重视电源常见故障的处理。1交流配电故障的处理
Power supply is one of the key equipment of communication system. The common fault of power system is general fault and emergency fault. The general fault refers to the fault that will not affect the communication security, including the lightning damage of the AC lightning arrester, the output of a single module, the damage of the monitoring unit, etc. The emergency fault refers to the fault affecting the communication security, including the AC power failure caused by the damage of AC input and control, DC sampling and control circuit damage caused by DC load power-down. Failure to handle the fault in time will result in the paralysis of the communication system and cause serious losses. Therefore, full attention should be paid to the handling of common faults in the power supply. 1 AC power distribution failure handling
