船舶生活污水系统电源改造

Power Transformation of Ship Domestic Sewage System

为响应国家节约能源和减少污染的号召,靠泊码头的所有船舶尽量接岸电使用,停止船舶柴油机的使用,这样就能减少燃油的消耗并且减少燃烧产生的烟雾污染,达到节能减排的目的。通常情况下码头只能提供0~440V岸电电源电压,但是有的船舶造船时生活污水系统真空马桶系统使用的是690V电压,这就使得船舶在接岸电时无法使用真空马桶,从而造成船员生活不便,直接导致船舶不具备接岸电的条件。

In response to the national call for energy conservation and pollution reduction,all ships berthing at the dock should try to connect to shore power and stop using ship diesel engines.This can reduce fuel consumption and smoke pollution generated by combustion,achieving the goal of energy conservation and emission reduction.Usually,the dock can only provide 0-440 V shore power supply voltage,but some ships use 690V voltage for the vacuum toilet system of the domestic sewage system during shipbuilding,which makes it impossible for ships to use vacuum toilets when connecting to shore power,resulting in inconvenience for crew members and directly leading to ships not having the conditions to connect to shore power.
