電暈放電基本結構及其分類形式
電(dian)(dian)(dian)(dian)暈(yun)放(fang)(fang)電(dian)(dian)(dian)(dian)又(you)稱低頻放(fang)(fang)電(dian)(dian)(dian)(dian)，是一種氣體(ti)在(zai)不(bu)均勻(yun)電(dian)(dian)(dian)(dian)場中(zhong)的(de)局部自持放(fang)(fang)電(dian)(dian)(dian)(dian)。常見的(de)兩種電(dian)(dian)(dian)(dian)暈(yun)放(fang)(fang)電(dian)(dian)(dian)(dian)基(ji)本裝置(zhi)如(ru)圖1.1所示(shi)，其中(zhong)：電(dian)(dian)(dian)(dian)壓＞15kV，頻率為20kHz~40kHz。外(wai)界大(da)氣壓下，在(zai)曲率半徑很小(xiao)的(de)電(dian)(dian)(dian)(dian)極(ji)(ji)上加載高電(dian)(dian)(dian)(dian)壓時，電(dian)(dian)(dian)(dian)極(ji)(ji)端電(dian)(dian)(dian)(dian)位(wei)增加。在(zai)尖端電(dian)(dian)(dian)(dian)極(ji)(ji)周(zhou)圍(wei)，電(dian)(dian)(dian)(dian)場中(zhong)存在(zai)顯(xian)著的(de)空間不(bu)均勻(yun)性，導致該放(fang)(fang)電(dian)(dian)(dian)(dian)區...
