外加电流阴极保护系统
工作原理 Principle
船体浸没在电解质的海水中会出现腐蚀，ICCP通过对钢质船体施加保护电流，使之阴极化，电流越大，阴极表面的电子积累越多，电位就越负，当电位负到一定程度时，钢铁表面达到等电位，腐蚀作用停止，船体得到保护。
To immerse the hull in sea water will cause corrosion.ICCP will protect metal’s hull from corrosion with applying protective current on it . The more the current is ,the more the electrons will be accumulated on cathode’s surface. When the potential is negative to a certain value,the metal surface will be equipotential,and then the hull will be protected from corrosion.

系统流程 Process
ICCP是由船上装备的直流电源，通过安装在船体上的辅助阳极对船体施加保护电流。整套ICCP系统 由恒电位仪、辅助阳极、参比电极、阳极屏蔽层及舵和推进器（螺旋桨）轴接地装置等组成。
The whole ICCP system consists of electric cabinet, auxiliary anode,conference cell , dielectric shield, rudder and propeller stock grounding. ICCP protects the hull with direct current through auxiliary anode installed on it .

性能特点 Product Features
