摘 要：输配电产品制造的质量工作重点是实施关键过程控制，关键过程控制要进行过程质量分析，而过程质量分析运用相关统计技术对数据和信息进行描述和推断，从而掌握关键过程质量状况，进行系统的改进和提升。通过三个案例，阐述了统计过程控制 (SPC)、测量系统分析 (MSA) 等方法在电线、变压器制造的关键过程中的应用，探讨了应用统计技术提升输配电相关产品制造质量的方法。案例应用结果表明，该法不但提高了输配电产品的实物质量，而且减少了质量损失，降低了制造成本。

Abstract: The implementation of crucial process control is the focus of power transmission and distribution product manufacturing quality.Critical process control requires process quality analysis,and this process quality analysis uses relevant statistical techniques to describe and infer data and information. These methods help to grasp the key process quality status. The system could be improved and upgraded. This paper uses three cases to illustrate the application of statistical process control (SPC), measurement system analysis (MSA) and other methods in the key processes of wire and transformer manufacturing. This paper discusses the application of statistical techniques to improve the manufacturing quality of power transmission and distribution related products. The case application results show that this method improves the physical quality of power transmission and distribution products, reduces quality loss, and descends manufacturing costs.
Key words: electric power transmission and distribution; transformer; wire and cable; key process; process capability; statistical process control; measurement system analysis
