摘要
通过对一套框架泄漏保护方案的分析,提出设置2套、3套框架泄漏保护的优化方案,该方案缩小了框架泄漏保护故障影响的范围,故障定位与查找更加迅速、准确,供电恢复快,提高了直流供电系统的可靠性和灵活性,减轻了运营风险和压力。
On basis of analyzing a scheme for a set of frame leakage protection, it proposes an optimum design scheme for leakage protection of 2 sets and 3 sets of frames, which narrows scope of influence caused by frame leakage protection failures, enables prompt and accurate fault location and trouble shooting, fast power supply recovery, heightens reliability and flexibility of DC power supply system, lessens operation risks and pressure.
