摘　　要：轮船在海里航行的时候,由于海水是电解质,会将船体表面的金属腐蚀。为了解决这一问题,设计了一种直流大电流发生器并将其应用于船体保护中。当传感器检测到海水开始腐蚀船体时,控制器开始控制直流大电流发生器的电流输出,通过不断地改变三相波的导通角来控制电流的大小,使整个船体呈现阴性,这就是船体的阴极保护。When the ship sails in the sea, the metal surface of its hull will be corroded by the seawater. To solve this problem, a high-current DC generator is designed for the protection of the hull in this paper. When the sensor de tects the hull is corroded by seawater, the controller will adjust the output current of the high-current DC generator. It will change the current value by changing the conduction angle of the three-phase wave to make the hull negative. This is cathode protection on the hull.
