The invention discloses a tail water excess pressure water supply cooling system of a water-turbine generator set. The tail water excess pressure water supply cooling system comprises a large-scale water-turbine generator set, a small-scale water-turbine generator set and a set cooling system. The large-scale water-turbine generator set is composed of a plurality of generators, and the outer walls of the plurality of generators are provided with a plurality of cooling fins. The large-scale hydraulic generator set flows to the small-scale hydraulic generator set through a first pipe set, the small-scale hydraulic generator set flows to the set cooling system through a second pipe set, the set cooling system flows to the large-scale hydraulic generator set through a third pipe set, and the set cooling system comprises a cooling box. The tail water excess pressure water supply cooling system of the water-turbine generator set is reasonable in structure, effective heat exchange cooling can be carried out on the large-scale water-turbine generator set so as to ensure that the large water-turbine generator set works within a safe temperature range, meanwhile, hot water for heat exchange can be effectively utilized and can be used in life or industry, and therefore use of other energy is greatly reduced.
Description
Technical field[0001]The present invention relates to the field of hydraulic generators, and in particular, to a water-saving water supply cooling system for a hydraulic generator set.Background technique[0002]In the hydropower station, the water supply system in the water generator sets is more common water supply methods: water pump water supply, self-evolutive water supply and water turbine top cover water supply and other means.[0003]In the high-water section, the water pump water supply solution is a relatively good economic effectiveness. However, in addition to the energy consumption of the pipeline, the water pump water supply is also satisfied with the additional energy consumption due to the low efficiency of the motor, and the motor. Moreover, the water pump water supply plan is more equipment, and the operation and maintenance is complex, and the failure that is often produced may result in an adverse effect on the unit shutdown.[0004]In recent years, in order to improve...
