      电(dian)力是指在电(dian)能源和(he)(he)机器力的感化下,绕组的尺(chi)寸或外形(xing)(xing)产(chan)生不(bu)可逆转的变(bian)(bian)(bian)更。化包含(han)轴向(xiang)和(he)(he)径向(xiang)尺(chi)寸的变(bian)(bian)(bian)经、器身(shen)位移、绕组歪曲(qu)、鼓(gu)包和(he)(he)匝间短(duan)(duan)路(lu)(lu)等(deng)。绕组变(bian)(bian)(bian)形(xing)(xing)是电(dian)力体(ti)系宁静运转的一(yi)大(da)隐患(huan)。跟着电(dian)力体(ti)系容量的增加,短(duan)(duan)路(lu)(lu)容量也(ye)在增大(da),出口(kou)短(duan)(duan)路(lu)(lu)形(xing)(xing)成绕组破坏(huai)变(bian)(bian)(bian)乱(luan)也(ye)有回升趋向(xiang);
