Recently, significant progress has been made in the field of generators, demonstrating continuous innovation and development in this area.
In terms of technological innovation, a patent called "an elastic supported generator" has been successfully applied for. The generator is equipped with fixed rods, dampers, support mechanisms, and adjustment mechanisms inside the base box. Through the cooperation of the support mechanism and dampers, it can provide elastic shock absorption function for the generator. When the pressure sensor detects abnormal spring elasticity, the adjusting mechanism can be used to compress the spring, making its elastic force the same as other supporting mechanisms, thereby improving the stability of the generator's elastic support without the need to replace the spring, effectively reducing cost expenditures
At the same time, a patent for a ventilation structure on a generator has emerged. This ventilation structure includes a generator housing and a ventilation installation plate. The ventilation installation plate is provided with ventilation holes, and the upper end of the holes is equipped with a circular groove and a matching circular plate. A rectangular plate is fixed at the bottom of the hole, and a motor is installed on the lower surface of the rectangular plate. Through the setting of fan blades, clamping devices, and switch devices, the time for external air to enter the generator can be reduced, and the filter screen can be cleaned more conveniently, reducing the labor intensity of workers, improving the cleaning efficiency and the working efficiency of the generator
In addition, there is a patent for a "generator maintenance device" that deserves attention. The device includes a chassis, a moving mechanism, maintenance components, and a guiding mechanism. In practical use, by matching the shape of the guiding mechanism with the stator slot, the maintenance device can move normally inside the stator and run in the preset direction. It can repair the gap between the stator and rotor without the need for maintenance personnel to enter the stator, avoiding the risk of falling and causing damage to the generator
In the progress of major projects, the stator of the world's first conventional island steam turbine generator set for the "Linglong One" was successfully lifted into place on the evening of September 14, 2024. Due to the small scope of the site, the lifting operation was difficult. Two cranes were used in parallel to lift the equipment, passing through the maintenance lifting hole and lifting it to the turbine platform. Finally, it was accurately positioned on the generator base, laying a solid foundation for the installation of the subsequent turbine generator unit
On October 16th, the No.1 generator of State Grid Liujiaxia Hydropower Plant in Gansu Province successfully completed the first isolated grid test of a hydroelectric generator in Gansu Province. The experiment lasted for 2 days and rigorously tested the load regulation capability, frequency stability, and fault response speed of the generator by simulating the isolated grid operating environment. All indicators met the expected requirements, effectively verifying the reliability and stability of the generator set under isolated grid conditions
These advances not only reflect breakthroughs in innovation and application of generator technology, but also provide stronger support for the future development of the energy sector, which is expected to push the generator industry to a higher level and better meet the society's demand for electricity.
