    摘 要:某沿?;痣姀S機組停運后,由于勵磁母線受潮導致的發(fā)電機轉子絕緣低,已成為影響機組正常啟動的頑固缺陷。討論了原有勵磁共箱封母存在的問題,對澆注母線的特性及改造可行性進行了論證,闡述了現場施工注意事項,并對改造后的運行情況跟蹤分析。經對比證實,進行澆注母線改造后,投運效果良好,優(yōu)于原共箱封母。
    關鍵詞:勵磁系統(tǒng);澆注母線;絕緣改造;應用實踐

    Abstract: After the generator system of a coastal thermal power plant was out of service, the low insulation of the generator rotor caused by the damp of the excitation buses has become a stubborn defect, affecting the normal startup of the system. In this paper, the problems of the original excitation common enclosed buses are discussed, the characteristics and feasibility of transformation of the cast bus are demonstrated,the precautions of site construction are explained, and the running state of the transformed cast bus is also tracked and analyzed. The comparison proves that the transformed cast bus runs better than the original one.
    Key words: excitation system; cast bus; insulation transformation; application
