气相色谱法、频响法及短路阻抗法是测试变压器绕组是否变形的重要手段，但单一的试验方法和试验数据对判断绕组变形存在一定的局限性。结合现场实际，提出应用色谱法进行检测后，再结合频响法和短路阻抗法进行分析的综合方法。应用结果表明：变压器绕组变形的综合分析方法能够有效、准确判断绕组的状态。
氣相色譜法、頻響法及短路阻抗法是測試變壓器繞組是否變形的重要手段，但單一的試驗方法和試驗數據對判斷繞組變形存在一定的跼限性。結閤現場實際，提齣應用色譜法進行檢測後，再結閤頻響法和短路阻抗法進行分析的綜閤方法。應用結果錶明：變壓器繞組變形的綜閤分析方法能夠有效、準確判斷繞組的狀態。

The method of gas chromatogram,frequency response and short-circuit impedance are important means to test whether transformer winding deforms. But using single test method and data to judge winding deformation exists limitation. The paper combines with field practice,puts forward the comprehensive method that after uses gas chromatography to detect then combining frequency response and short-circuit impedance methods to analyze. The application result shows that the comprehensive analysis method of transformer winding deformation can effectively and accurately determine the status of the winding.
