| 摘 要： | 舰船停靠码头后需要由岸上的电力系统为其供电．舰船上低压配电系统接地型式大多采用电源中性点不接地的IT系统．而陆地上民用低压配电系统的接地型式采用电源中性点直接接地的TN或TT系统。对于同一个低压配电系统．当船电和岸电电源中性点接地方式不同时．系统接地型式发生了改变。通过对引接岸电电源的舰船低压配电系统接地型式比较、分析...

| Abstract: | After ships dock at the shore,ashore power systems are needed for power supply of these ships.The grounding of low-voltage power distribution systems on ships mostly adopts ungrounded power neutral-point IT systems,while the grounding of low-voltage distribution systems on the land adopts TN or TT systems with power neutral points directly grounded.As for the same low-voltage distribution system,when the grounding methods for neutral points of power distribution systems on ships and on the land are differen... |
