Description

Technical Field

[0001] The utility model relates to the technical field of water cooling systems of wind turbine generator sets, in particular to a temperature abnormality early warning device for water cooling systems of wind turbine generator sets. Background Art

[0002] A wind turbine is a device that converts wind energy into electrical energy. It is mainly composed of components such as a wind wheel, a generator, a transformer, and a supporting structure. When the components are working, a large amount of heat is generated and a special cooling system is required for cooling. The cooling system mainly includes air cooling and water cooling, among which water cooling has a better cooling effect.

[0003] After searching, the Chinese patent publication number CN114320771B discloses a cooling status assessment and early warning device for the water cooling system of a wind turbine converter, including an early warning device for the water cooling system. The early warning device for the water cooling system includes a converter chassis, a cooling system, a protective jacket and a corner detector. The water cooling system is installed on the converter chassis and includes a refrigerator and circulating cooling water pipes on both sides installed on the refrigerator. The circulating cooling water pipes are evenly arranged inside the converter chassis. The circulating cooling water pipes are composed of several groups of cooling pipes. The protective jacket is embedded in the outside of the cooling pipe. Several groups of corner fixing plates are evenly arranged on the upper end of the protective jacket. The upper ends of the corner fixing plates are fixed to the inner wall of the converter chassis.

When the temperature sensor needs to be repaired, the cooling pipe and the deposition cavity need to be disassembled before the outer ring can be removed to repair the temperature sensor. There are many disassembly structures and the operation is cumbersome. Utility Model Content
