摘要:
組合電器由于本體結構封閉,部件複雜,局放缺陷定性及定位一直是個難題。在利用超聲波、特高頻局放檢測法的基礎上,創新性地引入高頻電容臂橋接檢測法進行組合電器局放檢測。通過多種檢測手段綜合診斷及解體後試驗對一起220 kV組合電器懸浮放電案例進行了詳細分析,分析結果表明:高頻電容臂橋接檢測法能夠有效輔助局放缺陷定性及定位;多種檢測方式相互驗證,可以提高局放缺陷定性的准確率;綜合采用聲—聲定位法及聲—電定位法,可以實現缺陷幹擾排除及精確定位,有效提高設備檢修維護效率。
Abstract:
Due to the closed structure and complex components,the determination and location of the partial discharge(PD) defects on composite apparatus have always been difficult problems. Based on the testing method of ultrasonic and ultra high frequency(UHF),this paper introduces a new method of bridge connection by capacitive arm in the high frequency(HF) to detect the PD defects. By using the variety of testing methods and making experiments after dismantling,this paper carries out a detailed analysis of suspension discharge case in a 220 kV composite apparatus,the analysis results show that: the method of bridge connection by capacitive arm in HF can effectively assist to determine and locate the PD defects;by verifying the variety of testing methods mutually,the accuracy of PD determination and location can be improved;by comprehensively using the ultrasonic-ultrasonic location method and combining ultrasonic and UHF location method,defect interference elimination and precise location can be realized,and the efficiency of equipment maintenance can be effectively improved.
