配电系统二次电源配置方案

Secondary Electrical Source Configuration Scheme on Power Distribution System

基于配电系统控制和操作的需要,在配网设计中应合理考虑电源系统采用交流还是直流系统,交流电源系统应在外引电源的同时设计由进线侧电压互感器引接电源,并设置不间断电源保证交流电源系统可靠性。对直流电源系统采用的整流设备和蓄电池组应符合其技术要求,并注意直流微断配置原则。

According to the control and operation need on power supply system,a reasonable choice should be made in AC and DC power system in design of the distribution network.In AC electrical source system,connecting power from voltage transformer should be designed when it linked external power.And uninterrupted power supply should be set to ensure the reliability of AC power system.Rectifiers and storage cells should be up to the mustard in DC electrical source system,besides the configuration principles of DC subminiature circuit breaker should be al-so adverted.
