Background technology
Boats and ships electric power supply from shore (Alternative Maritime Power is called for short AMP) technique functions comes from Los Angeles,U.S port in 2002.The cause of this technical application is that the U.S. has found in the coastal harbor city in census in 2000, and the cancer stricken number is unexpectedly up to 1500 people in every million people's mouth.And cancer arch-criminal occurred frequently has the excessive boats and ships by the bank that wharfs in the air, and the nitrogen dioxide noxious gas and the PM that are discharged with secondary machine generating can suck poisonous granule dust.According to the analysis at that time of Los Angeles executive authorities; Los Angeles harbor district every day from generating every day of alongside ultra Panamanian freight container counter on harbour secondary machine peculiar to vessel the quantity of the nitrogen dioxide noxious gas that discharges and PM granule dust reach 31.4 tons unexpectedly; This is equivalent to the quantity discharged of 500,000 roadlices! So the application legislation of Los Angeles,U.S executive authorities forbids that boats and ships go to dock the back with secondary machine generating.And since then, the U.S. imitates at each big harbour Los Angeles one after another, forbids that boats and ships pull in to shore the back with secondary machine generating, use bank without exception instead.Each the big shipping agency that gets into U.S. harbour in the world all need be equipped with the corresponding apparatus bank power supply of plugging into.
At first; Because of the safety of ship voltage that is limited by at that time is not higher than the 500V standard, very huge by the boats and ships electric power supply from shore system that the Cavotec Specimas in Europe provides, it is by the barge of a band hoisting crane; A midium voltage cable reel; High-tension switch cabinet, voltage transformer, low-pressure system and several low-voltage, high-current power cable reels are formed.The low-voltage high-current power source cable served receive electric boats and ships must rely on the hoisting crane on the barge.Use this cover system to connect the electric whole operation process of bank 3～4 hours consuming time as boats and ships.Obviously, this original method is difficult to promoted.
Now, Association International Des Registres has confirmed that current medium voltage insulation technology product meets ship electricity safety standard requirements.Boats and ships bank transmission system technical scheme has following two big types:
