Description

Technical Field

[0001] The utility model relates to the technical field of fan generators, in particular to a fan generator brake device. Background Art

[0002] A wind turbine generator is a device that converts wind energy into electrical energy. Wind turbine generators capture the power of wind, drive the blades to rotate, and drive the generator to rotate, thereby generating electricity. Depending on the installation location, wind turbine generators can be divided into onshore wind power and offshore wind power. Onshore wind power is a wind power generation method in which wind turbine generators are installed on land, while offshore wind power is a wind power generation method in which wind turbine generators are installed at sea. Offshore wind power can usually utilize more stable and strong wind resources, so the power generation efficiency and capacity factor are often higher. Wind turbine generators are the main equipment for realizing wind energy utilization. With the development of technology, their single-unit capacity continues to increase and their power generation efficiency is also continuously improving. At the same time, wind power generation, as a clean and renewable energy source, is of great significance for reducing greenhouse gas emissions and promoting the transformation of energy structure. During the operation of a wind turbine, the speed of the blades will increase with the increase of wind speed. When the wind speed is too high, the generator will generate too much electricity, which will increase the coil temperature and cause damage to the generator. In this case, a speed limiting brake device is needed. When the blade speed is too fast, heat will be generated between the brake pads and the brake disc during the braking process, which can easily cause the temperature inside the generator to rise and cause damage to the generator.
