船舶电力系统中主配电板照明分路开关及电缆的合理选型

本文主要阐述了，针对船舶电力绝缘系统和中性点接地系统不同的特点，主配电板照明分路开关及电缆的选型方法，并用ABB的docwin软件对该方法进行了验证。

This paper mainly elaborated, according to the different characteristics of the three phase A.C. three-wire insulated system and the three phase A.C. four-wire system with neutral earthed for ships electrical power system, how to select the breakers and the cables of the lighting branches on the main switchboard, and use the doewin software of ABB to prove the method is validate.
