摘 要：輸配電產品制造的質量工作重點是實施關鍵過程控制，關鍵過程控制要進行過程質量分析，而過程質量分析運用相關統計技術對數據和信息進行描述和推斷，從而掌握關鍵過程質量狀況，進行系統的改進和提升。通過三個案例，闡述了統計過程控制 (SPC)、測量系統分析 (MSA) 等方法在電線、變壓器制造的關鍵過程中的應用，探討了應用統計技術提升輸配電相關產品制造質量的方法。案例應用結果表明，該法不但提高了輸配電產品的實物質量，而且減少了質量損失，降低了制造成本。
關鍵詞：輸配電；變壓器；電線電纜；關鍵過程；過程能力；統計過程控制；測量系統分析

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
