摘要
针对小水电站的调速器油泵、空气压缩机和排水泵启动频繁的特点,其交流接触器触头易被电弧烧坏,影响机组安全运行,而采用无触点三相交流开关代替交流接触器可避免这种情况发生.
Aimed at the frequent starting feather of oil pumps of governor, air compressor and drainage pumps, the alternate switch is easily damged by electric arc and the no-contact switch which replaces alternate switch can avoid this accident.
