電暈放電基本結構及其分類形式
電(dian)(dian)(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)(dian)(dian)又(you)稱低頻放(fang)電(dian)(dian)(dian)(dian)(dian)，是(shi)一種氣(qi)體(ti)在(zai)不(bu)均(jun)勻(yun)電(dian)(dian)(dian)(dian)(dian)場(chang)中(zhong)(zhong)的(de)局部自持(chi)放(fang)電(dian)(dian)(dian)(dian)(dian)。常見的(de)兩種電(dian)(dian)(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)(dian)(dian)基本(ben)裝置如(ru)圖1.1所(suo)示，其(qi)中(zhong)(zhong)：電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)＞15kV，頻率為20kHz~40kHz。外界大氣(qi)壓(ya)(ya)下，在(zai)曲(qu)率半徑很小的(de)電(dian)(dian)(dian)(dian)(dian)極(ji)上加載高電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)時，電(dian)(dian)(dian)(dian)(dian)極(ji)端電(dian)(dian)(dian)(dian)(dian)位增(zeng)加。在(zai)尖端電(dian)(dian)(dian)(dian)(dian)極(ji)周圍(wei)，電(dian)(dian)(dian)(dian)(dian)場(chang)中(zhong)(zhong)存在(zai)顯著的(de)空(kong)間不(bu)均(jun)勻(yun)性，導致該放(fang)電(dian)(dian)(dian)(dian)(dian)區...
