Description

Technical Field

[0001] The invention belongs to the field of operation and maintenance of pumped storage power stations, and in particular relates to a stator maintenance platform. Background Art

[0002] Pumped-storage hydropower stations, also known as storage hydropower stations, utilize electricity generated during low-load periods to pump water to an upper reservoir and release it to a lower reservoir for power generation during peak load periods. They can convert excess electricity generated during low-load periods into high-value energy during peak periods. They are also suitable for frequency and phase modulation, stabilizing the frequency and voltage of the power system.

[0003] Generator sets are the core equipment of pumped-storage power plants, and their stators require regular maintenance. Unlike conventional generator stators, pumped-storage power station stators are bulky, and maintenance work requires extensive coverage of the stator's exterior, making them challenging. Traditional climbing or hanging methods require the generator set or stator itself as a foothold, which can easily damage the equipment and pose safety risks to personnel. Therefore, maintenance platforms are the only option.

[0004] In the design of the maintenance platform, the platform structure should conform to the morphological characteristics of the large-volume stator, so that workers can more easily reach the maintenance points on the stator surface. It is also necessary to fully ensure the stability of the structure without contacting the generator set. At the same time, it is best to be able to disassemble and assemble in parts to achieve flexible transportation and facilitate re-assembly. Summary of the Invention
