| 摘 要： | 分析了电力专用通信DC/DC直接挂于操作电源直流母线上，当发生馈线短路故障时DC/DC因自身短路保护而导致馈线开关不能可靠跳闸的问题，试验验证了此问题发生的机理，以及在DC/DC输出母线并联适当电解电容解决此问题的有效性。

| Abstract: | The paper analyzes how the DC/DC communication power(particular for power system) is connected to DC bus directly,and the problem when feeder switch short circuit occurs,it will not trip reliablely due to its own protection of DC/DC.The result verifies the mechnism when the problem occurs and the effectiveness to slove it by adding electrolysis electric capacity in the terminal of DC/DC bus. |
