摘要
结合干船坞电气使用场景和特点,从电气安全、连续的角度,对各种低压配电接地系统展开讨论,综合分析得出结论:干船坞配电采用ITN系统是合适的。
In combination with the electrical use scenario and characteristics of dry dock,and from the perspective of electrical safety and continuity,this paper conducts the research on various low⁃voltage distribution earthing systems,and concludes as follows through the comprehensive analysis:it is appropriate for electrical distribution of dry dock to adopt the ITN system.
