| Abstract: | The problems existed in control circuit of speed regulator for the Tianshengqiao Hydropower Station were analyzed, based on which the improvement measures were taken including adding a protector for the oil pump electric machinery, extending the number of connecting points for the oilcan of regulator, perfecting control program of the oil pump. After the alternation, the defects are overcome, which concerning electric machinery burning, oil pump of regulator starting up unduly and so on. The alternation ensures the reliability of regulator oil supply system. |
