无电地区的阴极保护电源是困扰管道工业发展的一大因素。国内外学者为此相继开发了太阳能电池、热电发生器、密闭循环发电机组(CCVT)、柴油机、油流动力发电机、风力发电机、热电堆等。然而,这众多的供电方式都有不同程度的局限性。 针对新疆塔里木石油开发和原油外输,管道勘察设计院和中国科学院电工研究所自1991年起在新疆轮台一 Cathodic protection power supply in the area without electricity is a major factor disturbing the development of the pipeline industry. Domestic and foreign scholars have successively developed solar cells, thermoelectric generators, closed loop generating units (CCVT), diesel engines, oil-flow power generators, wind turbines and thermopiles. However, there are varying degrees of limitations with this large number of power sources.
