摘要
建设变电站采用直流电压110V的控制方式已是国家电力发展的趋势,由此引起的断路器控制操作回路的电压降问题,可通过对操作控制回路电缆截面的计算,结合适当的接线方式和对电缆的正确选型得以解决。实际应用表明,该方法效果良好。
The DC 110 V control means for substations leads to voltage drop problem in circuit breaker control and operation circuit, which can be solved through sectional calculation for cables in the circuit along with proper connection means and correct cable type selection. Application results show the good effectiveness of the approach.
