在變(bian)頻(pin)電(dian)(dian)(dian)機中(zhong)(zhong)(zhong)，由于(yu)PWM變(bian)頻(pin)器(qi)的(de)(de)(de)(de)輸出(chu)電(dian)(dian)(dian)壓(ya)(ya)(ya)波形的(de)(de)(de)(de)特性(xing)，會(hui)導(dao)致(zhi)繞(rao)組(zu)匝間(jian)(jian)產生(sheng)局(ju)部(bu)放(fang)電(dian)(dian)(dian)。這(zhe)是因(yin)為(wei)在每一(yi)個(ge)(ge)基本頻(pin)率開(kai)始時，電(dian)(dian)(dian)壓(ya)(ya)(ya)的(de)(de)(de)(de)脈沖極(ji)(ji)性(xing)會(hui)發生(sheng)變(bian)化(hua)，導(dao)致(zhi)繞(rao)組(zu)承受一(yi)個(ge)(ge)二倍(bei)于(yu)尖(jian)(jian)峰電(dian)(dian)(dian)壓(ya)(ya)(ya)值的(de)(de)(de)(de)全幅(fu)(fu)電(dian)(dian)(dian)壓(ya)(ya)(ya)。同時，在一(yi)個(ge)(ge)散嵌繞(rao)組(zu)的(de)(de)(de)(de)三相(xiang)電(dian)(dian)(dian)機中(zhong)(zhong)(zhong)，不同相(xiang)的(de)(de)(de)(de)相(xiang)鄰(lin)二匝之(zhi)間(jian)(jian)的(de)(de)(de)(de)電(dian)(dian)(dian)壓(ya)(ya)(ya)極(ji)(ji)性(xing)可(ke)能會(hui)不同，全幅(fu)(fu)電(dian)(dian)(dian)壓(ya)(ya)(ya)的(de)(de)(de)(de)躍(yue)變(bian)也有可(ke)能達到二倍(bei)于(yu)一(yi)個(ge)(ge)尖(jian)(jian)峰電(dian)(dian)(dian)壓(ya)(ya)(ya)值。根(gen)據測試結果，在380/480V交流(liu)系統中(zhong)(zhong)(zhong)，測得的(de)(de)(de)(de)尖(jian)(jian)峰電(dian)(dian)(dian)壓(ya)(ya)(ya)值為(wei)～～。這(zhe)個(ge)(ge)全幅(fu)(fu)電(dian)(dian)(dian)壓(ya)(ya)(ya)的(de)(de)(de)(de)作(zuo)用(yong)(yong)下(xia)，繞(rao)組(zu)匝間(jian)(jian)會(hui)產生(sheng)局(ju)部(bu)放(fang)電(dian)(dian)(dian)。由于(yu)電(dian)(dian)(dian)離(li)作(zuo)用(yong)(yong)，氣(qi)隙中(zhong)(zhong)(zhong)會(hui)產生(sheng)空間(jian)(jian)電(dian)(dian)(dian)荷(he)(he)，形成一(yi)個(ge)(ge)與外加(jia)電(dian)(dian)(dian)場反向(xiang)的(de)(de)(de)(de)感(gan)應電(dian)(dian)(dian)場。當電(dian)(dian)(dian)壓(ya)(ya)(ya)極(ji)(ji)性(xing)改變(bian)時，這(zhe)個(ge)(ge)反向(xiang)電(dian)(dian)(dian)場與外加(jia)電(dian)(dian)(dian)場方(fang)向(xiang)一(yi)致(zhi)，導(dao)致(zhi)更高的(de)(de)(de)(de)電(dian)(dian)(dian)場產生(sheng)，增(zeng)加(jia)局(ju)部(bu)放(fang)電(dian)(dian)(dian)的(de)(de)(de)(de)數量(liang)，終(zhong)可(ke)能引起(qi)擊穿。測試還表(biao)明，作(zuo)用(yong)(yong)于(yu)繞(rao)組(zu)匝間(jian)(jian)絕(jue)緣的(de)(de)(de)(de)電(dian)(dian)(dian)沖擊大(da)小取決于(yu)導(dao)線特定的(de)(de)(de)(de)性(xing)能和PWM驅動電(dian)(dian)(dian)流(liu)的(de)(de)(de)(de)上(shang)升時間(jian)(jian)。如果上(shang)升時間(jian)(jian)小于(yu)μs，80%的(de)(de)(de)(de)電(dian)(dian)(dian)勢(shi)會(hui)加(jia)在繞(rao)組(zu)的(de)(de)(de)(de)前兩匝上(shang)，即上(shang)升時間(jian)(jian)越短，電(dian)(dian)(dian)沖擊越大(da)，匝間(jian)(jian)絕(jue)緣的(de)(de)(de)(de)壽命就越短。當頻(pin)率增(zeng)加(jia)時，局(ju)部(bu)放(fang)電(dian)(dian)(dian)會(hui)增(zeng)加(jia)，產生(sheng)熱(re)(re)量(liang)，進而(er)引起(qi)更大(da)的(de)(de)(de)(de)漏電(dian)(dian)(dian)流(liu)，使絕(jue)緣老(lao)化(hua)加(jia)速。因(yin)此，在變(bian)頻(pin)電(dian)(dian)(dian)機中(zhong)(zhong)(zhong)，局(ju)部(bu)放(fang)電(dian)(dian)(dian)、電(dian)(dian)(dian)介質加(jia)熱(re)(re)、空間(jian)(jian)電(dian)(dian)(dian)荷(he)(he)感(gan)應等因(yin)素共同作(zuo)用(yong)(yong)，導(dao)致(zhi)電(dian)(dian)(dian)磁線的(de)(de)(de)(de)過早損壞。
