Abstract

The invention discloses a stator winding vacuum water-cooled hidden pole generator, which relates to the field of motors. The invention aims to solve the problems of serious heat generation of the stator copper winding of the existing sequestered pole generator and large temperature difference along the axial direction of the stator copper winding. The stator water pipe is installed between the stator copper winding and the stator copper winding insulation along the circumferential direction, and the stator water pipe is in close contact with the stator copper winding and the stator copper winding insulation. The area surrounded by the stator water pipe, the stator copper winding and the stator copper winding insulation is extracted as Vacuum layer. There is flowing cooling water in the stator water pipe, and the section of the stator water pipe is square. The invention has a simple structure, effectively limits the temperature rise of the seriously heated stator copper winding in the sequestered pole generator and its ability to transfer heat, reduces the temperature of the stator copper winding and the insulation of the stator copper winding, and enhances the safety of the secluded pole generator Ability to operate stably.

Description

Technical field: [0001] The invention relates to a stator winding vacuum water-cooled hidden pole generator, which belongs to the field of motors. Background technique: [0002] The performance of a large-scale secluded pole generator has a great influence on the power supply and the stability of the grid. How to improve the single-unit capacity and operating performance of a secluded pole generator has become an important task in generator design. In order to increase the single-unit capacity of the secluded pole generator, it is necessary to increase the current density in the copper winding of the stator, that is, to increase the electromagnetic load of the generator, but this will inevitably lead to a corresponding increase in the loss of each component in the generator , leading to a further increase in the temperature rise of each component in the secluded pole generator, especially the temperature rise of the stator copper winding is more obvious, and it is very easy ...
