摘　　要：为缩小抽水蓄能机组磁极的质量偏差,提高磁极质量互换性,本文对影响抽水蓄能机组磁极质量偏差的因素进行了分析,从零部件质量偏差控制与磁极装配过程质量偏差控制两个角度开展了控制方法研究,阐述了通过提高磁极铜排尺寸一致性,特制配重片及采取成对制造的方式来降低磁极质量偏差的可行性,为类似工作提供参考。In order to reduce magnetic pole quality deviation of pumped storage units and improve interchangeability of magnetic pole quality,this paper analyzes the factors that affect quality deviation of the magnetic pole of pumped storage units, carries out control method research from two aspects of quality deviation control of the components and the quality deviation control of the magnetic pole assembly process. The feasibility of reducing the mass deviation of magnetic poles by improve the consistency of the size of the magnetic pole copper bar, making special counterweights and manufacturing in pairs provides a reference for similar work.
