摘要
为降低发电机定子线棒股线间的环流损耗,以降低线棒内部导体温度,提高效率及绝缘使用寿命,需要对线棒的股线进行换位。线棒股线换位通常采用在线棒的槽部作360°完全换位或小于360°的不完全换位,但也有一种较少应用的包含端部换位的540°换位方式。为确保540°换位方案顺利实施以及定子线棒导体的胶化、成型质量,通过工装工艺技术研究、设备改造,找到了合理的定子线棒540°换位制作工艺方案,为今后制作540°换位或其他非360°Robel换位线棒提供了宝贵经验。
In order to reduce the circulation loss between the wires of generator stator coil bar, reduce the conductor temperature inside the bars, improve the efficiency and the service life of the insulation, it is necessary to transpose the wires of the bars. The transposition of coil bar wire usually adopts 360° complete transposition or less than 360° incomplete transposition of slot part of coil bar, but there is also a less applied 540° transposition including end transposition. In order to ensure the smooth implementation of 540° transposition scheme and the gelling and forming quality of stator bar conductor, through the technological research and equipment transformation of tooling, a reasonable 540° transposition production scheme of stator bar is found, which provides valuable experience for the future production of 540° transposition or other non 360° Robel transposition bars.
