        摘 要:介紹了發(fā)電機(jī)定子繞組手包絕緣施加直流電壓測(cè)量方法,闡述了正接線(xiàn)和反接線(xiàn)試驗(yàn)方式的試驗(yàn)方法和實(shí)驗(yàn)原理,分析對(duì)比了兩種接線(xiàn)方式的優(yōu)缺點(diǎn),針對(duì)傳統(tǒng)的試驗(yàn)接線(xiàn)方式中存在的問(wèn)題提出了改進(jìn)措施,給出了一種新的基于傳統(tǒng)反接線(xiàn)方式的手包絕緣測(cè)試方法,既能滿(mǎn)足在定子通水狀態(tài)下進(jìn)行試驗(yàn),又極大地縮小了試驗(yàn)設(shè)備容量,工程運(yùn)用表現(xiàn)良好。

        Abstract: Introduction was made to the method of direct current voltage measuring imposing on the hand-making insulation of generator stator winding. This paper expounded the test method and experimental principle of positive and reverse connection test modes, and analyzed and compared two kinds of relative merits of two types of connection modes. Aiming at the problems existing in traditional test connection mode, this paper proposed the improved measures and gave a new kind of hand-making insulation test method, which not only met the requirements of the test under conditions of stator through-water state, but also greatly reduced the test facility capacity, with good engineering application.
        Key words: hand-making insulation; surface potential; reverse connection mode optimization
