背景技术Background technique
大型隐极发电机单机容量的增加会导致发电机端部区域磁密明显增加，进而定子端部铁心的损耗和温升急剧增大，发热严重的定子端部铁心就会发生热膨胀，受到发电机内固定件的约束作用后定子端部铁心因挤压作用而翘曲和变形，导致定子端部铁心松动，特别是在隐极发电机特殊工况，例如进相运行时，温度过高的定子端部铁心甚至会发生断裂和挤压定子绕组的现象，严重的话会烧毁定子端部铁心，影响到了隐极发电机的使用寿命和安全运行。The increase of the unit capacity of a large secluded pole generator will lead to a significant increase in the magnetic density at the end of the generator, and a sharp increase in the loss and temperature rise of the iron core at the end of the stator. The iron core at the end of the stator is warped and deformed due to extrusion due to the restraint of the internal fixings, resulting in the loosening of the iron core at the end of the stator, especially in the special working conditions of the secluded pole generator, such as the stator with high temperature during phase advance operation. The iron core at the end may even break and squeeze the stator windings. In severe cases, the iron core at the end of the stator may be burned, affecting the service life and safe operation of the sequestered pole generator.
传统的定子端部铁心是由硅钢片叠压而成的实心结构。定子端部铁心的损耗较高，通风冷却效果较差，产生的热量不能及时被周围的冷却流体带走，导致定子端部铁心的温度较高，需要采用合理的冷却技术来降低定子端部铁心的温度，使其在允许的温度范围内，延长隐极发电机的使用寿命。The traditional stator end core is a solid structure formed by laminating silicon steel sheets. The loss of the iron core at the end of the stator is high, the ventilation and cooling effect is poor, and the heat generated cannot be taken away by the surrounding cooling fluid in time, resulting in a high temperature of the iron core at the end of the stator. Reasonable cooling technology is required to reduce the iron core at the end of the stator. temperature, so that it is within the allowable temperature range, prolonging the service life of the selenium pole generator.
