變(bian)(bian)(bian)壓(ya)(ya)器繞(rao)(rao)(rao)組(zu)(zu)變(bian)(bian)(bian)形測(ce)試儀(yi)(yi)(yi)(yi)又稱電力變(bian)(bian)(bian)壓(ya)(ya)器繞(rao)(rao)(rao)組(zu)(zu)變(bian)(bian)(bian)形檢測(ce)儀(yi)(yi)(yi)(yi)、變(bian)(bian)(bian)壓(ya)(ya)器繞(rao)(rao)(rao)組(zu)(zu)變(bian)(bian)(bian)形測(ce)量儀(yi)(yi)(yi)(yi)、變(bian)(bian)(bian)壓(ya)(ya)器繞(rao)(rao)(rao)組(zu)(zu)變(bian)(bian)(bian)形分析(xi)儀(yi)(yi)(yi)(yi)，DYBX-F變(bian)(bian)(bian)壓(ya)(ya)器繞(rao)(rao)(rao)阻變(bian)(bian)(bian)形測(ce)試儀(yi)(yi)(yi)(yi)采用掃頻法對變(bian)(bian)(bian)壓(ya)(ya)器繞(rao)(rao)(rao)組(zu)(zu)特性(xing)進行測(ce)量，不對變(bian)(bian)(bian)壓(ya)(ya)器吊罩、拆裝的(de)情況(kuang)下，通過檢測(ce)各(ge)繞(rao)(rao)(rao)組(zu)(zu)的(de)幅(fu)頻響應特性(xing)，對6kV及以上變(bian)(bian)(bian)壓(ya)(ya)器，準(zhun)確測(ce)量繞(rao)(rao)(rao)組(zu)(zu)的(de)扭曲、鼓包或(huo)移位等變(bian)(bian)(bian)形情況(kuang)。

變(bian)壓(ya)器(qi)繞組直流電阻測試儀 當(dang)變(bian)壓(ya)器(qi)在試驗過程中(zhong)(zhong)出現匝間、相(xiang)間短路(lu)，在運行(xing)中(zhong)(zhong)出現短路(lu)或其他(ta)故障因(yin)電磁拉力造成線圈(quan)(quan)移位(wei)，在運輸(shu)過程中(zhong)(zhong)發送碰撞造成線圈(quan)(quan)相(xiang)對移位(wei)，這些因(yin)素都會使變(bian)壓(ya)器(qi)分布(bu)參數發生(sheng)(sheng)變(bian)化(hua)，其頻(pin)(pin)域響(xiang)應也發生(sheng)(sheng)變(bian)化(hua)，根(gen)據頻(pin)(pin)域響(xiang)應曲線即可判斷變(bian)壓(ya)器(qi)的變(bian)形程度
