摘要
通过对船电采用IT系统存在问题及解决措施的分析,说明船电电缆和船体间存在的泄漏电流不容忽视,应重视对杂散电流引起的腐蚀进行防护;船舶与岸基码头间是不能连接PE线的,人为在码头和船舶间连接PE线不仅不安全,而且后果极其严重;港口岸电设计,实际只有IT系统一种可能。
Through the analysis on existing problems and solutions for the IT system adopted for marine power supplying system, it is indicated that the leakage current between the marinepower supplying system cables and the hull cannot be ignored, and attention should be paid to the protection against corrosion caused by stray current; PE conductor cannot be used as a connection between the ship and the shore- based dock （not only unsafe, but also may lead to serious consequences）, and IT system is actually the only choice for shore power supplying design of the port.
