Description

Technical Field

[0002] As the requirements for generator design and manufacturing continue to increase, the pursuit of material utilization has led to a gradual increase in the electromagnetic load level of the generator. This has led to a further increase in the copper loss, iron loss, stray loss, mechanical loss and other losses per unit volume of the stator during operation, which has significantly increased the operating temperature. Since the high temperature environment can easily cause the unit stator to overheat, the service life of key insulation materials is shortened, which has brought harm to the reliability, stability and safety of the unit, and has had a serious impact on the production and operation safety of users.

[0003] At the same time, as users' requirements for equipment reliability, stability and safety continue to increase, controlling the stator operating temperature of the unit becomes increasingly important. In order to solve this problem, relevant new materials and new processes have begun to emerge. However, these new materials and new processes often indirectly control the stator operating temperature of the unit by increasing the maximum allowable operating temperature of the material. This is difficult to achieve, and the R&D and production costs are high, and the technical and economic benefits are poor. Therefore, a multi-wind zone forced heat dissipation motor casing is needed to solve the problem of equipment damage caused by a significant increase in operating temperature. Utility Model Content

[0011] Compared with the prior art, the utility model has the following beneficial effects: through the alternating arrangement of hot air zones and cold air zones, the air can flow more effectively during the heat dissipation process; at the same time, the utility model adopts a multi-wind zone casing to force the heat dissipation of the generator stator and the generator rotor, thereby improving the heat dissipation effect of the generator stator and the generator rotor, reducing the operating temperature rise of the generator stator and the generator rotor, eliminating overheating of the unit, increasing the service life of the unit, and ensuring the reliability, stability and safety of the unit operation.
