高寒湿冷山区配电线路直流融冰方法的研究

Study of DC ice melting means for distribution lines in cold and wet mountainous areas

结合高寒湿冷山区地方电网配电线路的特点,研究适用于高寒湿冷山区配电线路的融冰装置。依据线路特点,分别制定相应融冰方法,研制配合电网长线路、短线路和超短线路的低成本直流融冰装置,从而提高高寒湿冷山区地方电网线路抵御雨雪冰冻灾害的能力,并介绍了融冰装置现场试验结果。

Combined with the characteristics of distribution lines of local power grid in cold and wet mountainous ar- eas, study of ice melting device was conducted. Different ice melting means was developed according to the charac- teristics of power lines. Low-cost DC ice melting devices were designed for long lines, short lines and extra-short lines respectively, so as to upgrade the capability of power lines against freezing rain and snow disaster. An intro- duction was made on the field test results of ice melting device.
