1对电源系统设备的基本要求1.1可靠性要高若电源系统不能输出规定电流,电压超出允许波动范围,杂音电压高于允许值的时间并持续10s以上者均判定为系统故障。原交流系统中的电压、频率或波形畸变超出规定范围持续时间大于60s者均判定为故障。为此,要保证通信电源系统的可靠性,有条件的专网应尽量从两个不同的地方引入2路市电输入,并设置2路市电电能自动倒换装置;所用设备要选用可靠性高的高频开关整流设备,采用模块化、热插拔
1 The basic requirements of the power system equipment 1.1 High reliability If the power supply system can not output the specified current, the voltage exceeds the allowed fluctuation range, the noise voltage is higher than the allowable value of the time and persist for more than 10s are judged as system failure. The original AC system voltage, frequency or waveform distortion beyond the scope of the provisions of the duration of more than 60s were judged as fault. To this end, to ensure the reliability of communication power supply system, the conditional private network should be introduced from two different places as much as possible 2-way mains input and set 2-way mains power automatic switching device; the use of equipment to choose high reliability The high-frequency switching rectifier equipment, modular, hot-swappable
