摘 要:某沿?;痣姀S機(jī)組停運(yùn)后,由于勵(lì)磁母線受潮導(dǎo)致的發(fā)電機(jī)轉(zhuǎn)子絕緣低,已成為影響機(jī)組正常啟動(dòng)的頑固缺陷。討論了原有勵(lì)磁共箱封母存在的問(wèn)題,對(duì)澆注母線的特性及改造可行性進(jìn)行了論證,闡述了現(xiàn)場(chǎng)施工注意事項(xiàng),并對(duì)改造后的運(yùn)行情況跟蹤分析。經(jīng)對(duì)比證實(shí),進(jìn)行澆注母線改造后,投運(yùn)效果良好,優(yōu)于原共箱封母。
關(guān)鍵詞:勵(lì)磁系統(tǒng);澆注母線;絕緣改造;應(yīng)用實(shí)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
