Description

Technical Field

[0001] The utility model relates to the technical field of hydropower generation equipment, in particular to a speed regulator device for a hydropower station. Background Art

[0002] The speed governor is an essential piece of electromechanical equipment for hydropower station operation. It typically consists of four separate units: a pressure oil tank, a return oil tank, a hydraulic control cabinet, and an electrical control cabinet. These units are interconnected by numerous medium- and high-pressure oil and gas pipelines and valves, making their layout more complex than other electromechanical equipment. There are two common layout options for speed governors in hydropower stations: one is located on the generator floor, using a sunken layout with openings in the floor; the other is located on the floor of the intermediate or turbine level, using a floor-mounted layout. In the first layout, the governor's main oil and gas pipelines are suspended from the ceiling above the intermediate level. This eliminates obstruction to operational access and improves aesthetics. However, the elevated installation position makes maintenance and inspection difficult. In the event of a pipeline leak, medium- and high-pressure oil and gas could be sprayed directly onto the intermediate level, posing a safety hazard. In the second layout, the speed governor and hydraulic system are both floor-mounted, making the equipment and piping easier to inspect and maintain. However, the oil and gas pipelines are routed above ground, making layout difficult and impacting the overall aesthetics of the power station and operational access. Utility Model Content
