基于VB的船用低压开关电缆选型程序设计

Programming of marine low-voltage switch and cable selection based on VB

低压开关的选型是船舶低压配电板和分电箱设计的核心内容,而相应的船用电缆的选型也是船舶低压电力系统设计的一项重要内容。利用VB技术,对船用低压电缆开关的选型进行计算机模拟,并对选型后的电缆和开关进行了自动匹配,为进一步优化船舶电站的设计提供了一定依据。

The selection of low voltage switch is vital for shipboard low voltage switchboard and sub-switchboard design,wherein the selection of the cable is important as well.In this paper,a computation model of automatic select system in shipboard power station is presented with visual interface and structured programming realized by VB.The main function includes current calculation according to different loads,cable selection,switch selection,matching of cable and switch.They provide the base for further optimization of electrical computation in power station design.
