1.閃絡-指高壓電器(如高壓絕緣子)在絕緣表面發生的放電現象,成為表面閃絡,簡稱閃絡。
 
 絕緣閃絡:絕緣材料在電場作用下,尚未發生絕緣結構的擊穿時,在其表面或與電極接觸的空氣(離子化氣體)中發生的放電現象,成為絕緣閃絡。
 
 1.電壓波形直流、工頻正弦及沖擊電壓下,擊穿機理不同,所測的擊穿場強也不同,工頻交流電壓下的擊穿場強比直流和沖擊電壓下的低得多
 
 2..電壓作用時間,無論電擊穿還是熱擊穿都需要時間,隨著加壓時間的增長,擊穿電壓明顯下降。
 
 3、電場的均勻性及電壓的極性,電場不均勻往往測得的電壓比本征擊穿值低。
 
 4、試樣的厚度與不均勻性試樣的厚度增加,電極邊緣電場就更不均勻,試樣內部的熱量更不易散發,試樣內部的含有缺陷的幾率加大,這些都會使擊穿場強下降。
 
 5.環境條件試樣周圍的環境條件,如溫度、濕度以及壓力等都會影響試樣的擊穿場強;溫度升高,通常會使擊穿場強下降;濕度加大,會使擊穿場強下降;氣壓對擊穿場強的影響,主要是對氣體而言。氣壓高,擊穿場強升高:但接近真空時,也會使擊穿場強升高。另外還有:時間、輻射、機械力、電極材料及極性效應。
 
 在強電場作用下,電介質喪失電絕緣能力的現象。分為固體電介質擊穿、液體電介質擊穿和氣體電介質擊穿3種。
 
 固體電介質擊穿導致擊穿的較低臨界電壓稱為擊穿電壓。均勻電場中,擊穿電壓與介質厚度之比稱為擊穿電場強度(簡稱擊穿場強,又稱介電強度)。它反映固體電介質自身的耐電強度。不均勻電場中,擊穿電壓與擊穿處介質厚度之比稱為平均擊穿場強,它低于均勻電場中固體介質的介電強度。固體介質擊穿后,由于有巨大電流通過,介質中會出現熔化或燒焦的通道,或出現裂紋。脆性介質擊穿時,常發生材料的碎裂,可據此破碎非金屬礦石。固體電介質擊穿有3種形式:電擊穿、熱擊穿和電化學擊穿。電擊穿是因電場使電介質中積聚起足夠數量和能量的帶電質點而導致電介質失去絕緣性能。熱擊穿是因在電場作用下,電介質內部熱量積累、溫度過高而導致失去絕緣能力。電化學擊穿是在電場、溫度等因素作用下,電介質發生緩慢的化學變化,性能逐漸劣化,較終喪失絕緣能力。固體電介質的化學變化通常使其電導增加,這會使介質的溫度上升,因而電化學擊穿的較終形式是熱擊穿。溫度和電壓作用時間對電擊穿的影響小,對熱擊穿和電化學擊穿的影響大;電場局部不均勻性對熱擊穿的影響小,對其他兩種影響大。
 
 液體電介質擊穿純凈液體電介質與含雜質的工程液體電介質的擊穿機理不同。對前者主要有電擊穿理論和氣泡擊穿理論,對后者有氣體橋擊穿理論。沿液體和固體電介質分界面的放電現象稱為液體電介質中的沿面放電。這種放電不僅使液體變質,而且放電產生的熱作用和劇烈的壓力變化可能使固體介質內產生氣泡。經多次作用會使固體介質出現分層、開裂現象,放電有可能在固體介質內發展,絕緣結構的擊穿電壓因此下降。脈沖電壓下液體電介質擊穿時,常出現力度強氣體沖擊波(即電水錘),可用于水下探礦、橋墩探傷及人體內臟結石的體外破碎。
