Technical Field

[0002] Hydropower plants are power generation facilities that convert the energy of water flow into electrical energy. They are usually built in river sections with large water drop or stable flow. The core of a hydropower plant consists of water-blocking, water-discharging, and water-diverting structures, as well as turbine generator units. By building dams to raise the water level and create a head difference, the water flow drives the turbine to rotate, and the turbine then drives the generator to cut magnetic field lines to generate electricity. Hydropower plants have advantages such as being clean and renewable, having low operating costs, and being flexible in peak shaving, and are an important part of the renewable energy power generation system.

[0003] The generator governor is the core control device used to regulate the speed of the hydro-generator unit. Its core function is to adjust the water intake of the turbine in real time according to the changes in grid load, maintain the unit speed at the rated value, and ensure that the frequency of the output power meets the grid standard. By detecting the speed deviation signal, it drives the actuator to change the opening of the guide vanes or blades to realize closed-loop speed control. It also has start-stop control, load regulation and fault protection functions, and is a key piece of equipment for the stable operation of hydropower stations.

[0004] In traditional speed controllers, the transmission gaps, such as the connection between the shaft and the housing, and the moving parts of the lever, are the core channels for dust to enter. Simple rubber seals are prone to failure due to friction and wear, which can cause transmission jamming and reduced adjustment accuracy after dust enters.

[0005] Therefore, it is necessary to provide a generator speed governor with dustproof function to solve the above-mentioned technical problems. Utility Model Content
