摘要
某企业一批用于风力发电塔机设备滤除3000HZ高频有害谐波的电抗器在做半成品测试时发现电感值不合格。经分析后确立对电抗器绝缘板总的气隙值进行调控的方案。经试验测定该方案不仅可行,而且借助Minitab软件通过过程能力指数cpk统计分析,改善后的方案,公差范围更加集中,产品合格率达到99%。
The semi-product of reactors for wind power generation in 3000HZ humorous filtering met the quality issue as inductance out of spec. The solution is to adjust the total gap ofinsulation board after studying. It＇s workable and available process per trial run result. And, the first pass yield is increased to 99% with narrow tolerance after project improvement while we use the process capability （CPK）to present.
