阅读说明：本技术 一种用于水力发电的三相永磁同步发电机 (Three-phase permanent magnet synchronous generator for hydroelectric power generation ) 是由 金文奎 安保靖 金艳 张志� 于海涛 于 2019-10-10 设计创作，主要内容包括：本申请实施例公开了一种用于水力发电的三相永磁同步发电机,所述该发电机取消了常规发电机转子的磁极线圈,改用永磁磁块拼装,结构简单,体积小、重量轻。取消了复杂的励磁系统。发电系统自动化更加简化。维修保养方便。采购成本是常规发电机的50%,重量和体积是常规发电机30%,效率提升7%(铜、铁及摩擦损耗下降,无励磁功率损耗),节能效果特别显著。针对东方红电站的发电机改造解决了常规电机体积和重量结构受限制的不能进入的特殊问题。(The embodiment of the application discloses a three-phase permanent magnet synchronous generator for hydroelectric power generation, the generator cancels a magnetic pole coil of a conventional generator rotor, is assembled by permanent magnet blocks instead, and is simple in structure, small in size and light in weight. A complex excitation system is eliminated. The automation of the power generation system is more simplified. The maintenance is convenient. The procurement cost is 50% of the conventional generator, the weight and the volume are 30% of the conventional generator, the efficiency is improved by 7% (the friction loss of copper, iron and the excitation power is not reduced), and the energy-saving effect is particularly obvious. The special problem that the conventional motor is limited in size and weight structure and cannot enter is solved by modifying the generator of the Dongfanghong power station.)
