100KV直流耐電壓強度試驗機   介電擊穿強度是指在強電場作用下，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

導致擊穿的最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,最終喪失絕緣能力.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,因而電化學擊穿的最終形式是熱擊穿.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,常出現強力氣體沖擊波（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.

氣體電介質擊穿

在電場作用下氣體分子發生碰撞電離而導致電極間的貫穿性放電.其影響因素很多,主要有作用電壓,電板形狀,氣體的性質及狀態等.氣體介質擊穿常見的有直流電壓擊穿,工頻電壓擊穿,高氣壓電擊穿,沖擊電壓擊穿,高真空電擊穿,負電性氣體擊穿等.空氣是很好的氣體絕緣材料,電離場強和擊穿場強高,擊穿后能迅速恢復絕緣性能,且不燃,不爆,不老化,無腐蝕性,因而得到廣泛應用.為提供高電壓輸電線或變電所的空氣間隙距離的設計依據（高壓輸電線應離地面多高等）,需進行長空氣間隙的工頻擊穿試驗.

介電強度是一種材料作為絕緣體時的電強度的量度.它定義為試樣被擊穿時,單位厚度承受的最大電壓,表示為伏特每單位厚度.物質的介電強度越大,它作為絕緣體的質量越好.

介電強度，是材料抗高電壓而不產生介電擊穿能力的量度，將試樣放置在電極之間，并通過一系列的步驟升高所施加的電壓直到發生介電擊穿，以次測量介電強度。盡管所得的結果是以kv/mm為單位的，但并不表明與試樣的厚度無關。因此，只有在試樣厚度相同的條件下得到各種材料的數據才有可比性。

介電系數，是一個在電的位移和電場強度之間存在的比例常量。這一個常量在自由的空間（一個真空）中是8.85?10的-12次方法拉第/米（F/m）。在其它的材料中，介電系數可能差別很大，經常遠大于真空中的數值，其符號是eo。 在工程應用中，介電系數時常在以相對介電系數的形式被表達，而不是絕對值。如果eo表現自由空間（是，8.85?10的-12次方F/m）的介電系數，而且e是在材料中的介電系數，則這個材料的相對介電系數（也叫介電常數）由下式給出：ε1=ε / εo=ε?1.13?10的11次方 很多不同的物質的介電常數超過1。這些物質通常被稱為絕緣體材料，或是絕緣體。普遍使用的絕緣體包括玻璃，紙，云母，各種不同的陶瓷，聚乙烯和特定的金屬氧化物。絕緣體被用于交流電（AC），聲音電波（AF）和無線電電波（射頻）的電容器和輸電線路。

Dielectric strength is a measure of the electrical strength of a material when used as an insulator It is defined as the maximum voltage per unit thickness that the sample can withstand when it is broken down, expressed in volts per unit thickness The higher the dielectric strength of a substance, the better its quality as an insulator

Dielectric strength is a measure of a material's ability to withstand high voltage without dielectric breakdown. The sample is placed between electrodes and the applied voltage is increased through a series of steps until dielectric breakdown occurs, in order to measure the dielectric strength. Although the results obtained are in kV/mm units, it does not indicate that they are independent of the thickness of the sample. Therefore, comparability of data for various materials can only be achieved when the sample thickness is the same.

The dielectric constant is a proportional constant that exists between the displacement of electricity and the strength of the electric field. This constant in free space (a vacuum) is 8.85 ? 10 ^ -12 times the method pull per meter (F/m). In other materials, the dielectric constant may vary greatly, often much greater than the value in vacuum, and its symbol is eo. In engineering applications, the dielectric constant is often expressed in the form of relative dielectric constant rather than absolute value. If eo represents the dielectric constant of free space (8.85 ? 10 ^ -12 F/m), and e is the dielectric constant in the material, then the relative dielectric constant (also known as the dielectric constant) of this material is given by the following equation: The dielectric constant of many different substances exceeds 1, which is the 11th power of ε 1=ε/ε o=ε? 1.13 ? 10. These substances are commonly referred to as insulating materials or insulators. Commonly used insulators include glass, paper, mica, various types of ceramics, polyethylene, and specific metal oxides. Insulators are used in capacitors and transmission lines for alternating current (AC), acoustic waves (AF), and radio waves (RF).
