在(zai)此(ci)全幅電(dian)(dian)(dian)(dian)壓(ya)作用(yong)(yong)下繞(rao)(rao)組之(zhi)間(jian)會產(chan)生表(biao)面局(ju)部(bu)放電(dian)(dian)(dian)(dian)。是因為電(dian)(dian)(dian)(dian)壓(ya)的(de)作用(yong)(yong)會導致(zhi)氣隙中(zhong)的(de)空氣分子(zi)電(dian)(dian)(dian)(dian)離，產(chan)生電(dian)(dian)(dian)(dian)荷。這些電(dian)(dian)(dian)(dian)荷會形成一個(ge)與外加(jia)(jia)(jia)電(dian)(dian)(dian)(dian)場(chang)方(fang)向(xiang)相反的(de)感(gan)應(ying)電(dian)(dian)(dian)(dian)場(chang)。當電(dian)(dian)(dian)(dian)壓(ya)的(de)極(ji)性改(gai)變，感(gan)應(ying)電(dian)(dian)(dian)(dian)場(chang)與外加(jia)(jia)(jia)電(dian)(dian)(dian)(dian)場(chang)方(fang)向(xiang)一致(zhi)，導致(zhi)一個(ge)更高的(de)電(dian)(dian)(dian)(dian)場(chang)產(chan)生。這會導致(zhi)局(ju)部(bu)放電(dian)(dian)(dian)(dian)的(de)數(shu)量增加(jia)(jia)(jia)，終(zhong)引起擊(ji)穿。作用(yong)(yong)于繞(rao)(rao)組間(jian)絕(jue)緣的(de)電(dian)(dian)(dian)(dian)沖擊(ji)大(da)小(xiao)取決于導線(xian)(xian)的(de)特定性能(neng)和(he)PWM驅動(dong)電(dian)(dian)(dian)(dian)流的(de)上(shang)升(sheng)(sheng)時(shi)(shi)(shi)間(jian)。如果(guo)上(shang)升(sheng)(sheng)時(shi)(shi)(shi)間(jian)小(xiao)于微秒級，80%的(de)電(dian)(dian)(dian)(dian)勢將加(jia)(jia)(jia)在(zai)繞(rao)(rao)組的(de)前(qian)兩匝(za)上(shang)。換句話說，上(shang)升(sheng)(sheng)時(shi)(shi)(shi)間(jian)越短，電(dian)(dian)(dian)(dian)沖擊(ji)越大(da)，繞(rao)(rao)組間(jian)絕(jue)緣的(de)壽命就越短。當頻率(lv)增加(jia)(jia)(jia)時(shi)(shi)(shi)，局(ju)部(bu)放電(dian)(dian)(dian)(dian)也會增加(jia)(jia)(jia)，產(chan)生熱量。這些熱量會引起更大(da)的(de)漏電(dian)(dian)(dian)(dian)流，使(shi)繞(rao)(rao)組溫度上(shang)升(sheng)(sheng)，加(jia)(jia)(jia)速絕(jue)緣老化(hua)。總之(zhi)，在(zai)變頻電(dian)(dian)(dian)(dian)機中(zhong)，局(ju)部(bu)放電(dian)(dian)(dian)(dian)、電(dian)(dian)(dian)(dian)介質加(jia)(jia)(jia)熱、空間(jian)電(dian)(dian)(dian)(dian)荷感(gan)應(ying)等因素共同作用(yong)(yong)導致(zhi)電(dian)(dian)(dian)(dian)磁線(xian)(xian)的(de)過早損壞(huai)。
