    摘 要:對于新建、擴建發(fā)電機組,在基建調(diào)試過程中必須對電流互感器(CT)的變比、準確級、接線、極性等進行檢查確認。對調(diào)試過程中極性判別及接線檢查、伏安特性及10%誤差曲線校核、倒送電及整套啟動過程CT檢查進行了原理分析,并給出了具體調(diào)試步驟,確保CT的接線、極性等完全正確。
    關鍵詞:基建調(diào)試;電流互感器;極性檢查

    Abstract: For the newly built and expanded generator sets, the transformation ratio, accuracy level, wiring, polarity of current transformer(CT) must be checked and confirmed during the process of infrastructure commissioning.The principle analysis of polarity discrimination and wiring inspection, volt-ampere characteristics and 10% error curve verification, reverse power transmission and CT inspection of the entire start-up process during the debugging process are carried out, and specific debugging steps are given to ensure the wiring and polarity of the CT are completely correct.
    Key words: infrastructure commissioning; current transformer; polarity check
