100KV直流耐電壓強(qiáng)度試驗(yàn)機(jī)   介電擊穿強(qiáng)度是指在強(qiáng)電場作用下，電介質(zhì)喪失電絕緣能力的現(xiàn)象。分為固體電介質(zhì)擊穿，液體電介質(zhì)擊穿和氣體電介質(zhì)擊穿3種。

固體電介質(zhì)擊穿

導(dǎo)致?lián)舸┑淖畹团R界電壓稱為擊穿電壓.均勻電場中,擊穿電壓與介質(zhì)厚度之比稱為擊穿電場強(qiáng)度（簡稱擊穿場強(qiáng),又稱介電強(qiáng)度）.它反映固體電介質(zhì)自身的耐電強(qiáng)度.不均勻電場中,擊穿電壓與擊穿處介質(zhì)厚度之比稱為平均擊穿場強(qiáng),它低于均勻電場中固體介質(zhì)的介電強(qiáng)度.固體介質(zhì)擊穿后,由于有巨大電流通過,介質(zhì)中會(huì)出現(xiàn)熔化或燒焦的通道,或出現(xiàn)裂紋.脆性介質(zhì)擊穿時(shí),常發(fā)生材料的碎裂,可據(jù)此破碎非金屬礦石.

固體電介質(zhì)擊穿有3種形式:電擊穿,熱擊穿和電化學(xué)擊穿.

電擊穿是因電場使電介質(zhì)中積聚起足夠數(shù)量和能量的帶電質(zhì)點(diǎn)而導(dǎo)致電介質(zhì)失去絕緣性能.熱擊穿是因在電場作用下,電介質(zhì)內(nèi)部熱量積累,溫度過高而導(dǎo)致失去絕緣能力.電化學(xué)擊穿是在電場,溫度等因素作用下,電介質(zhì)發(fā)生緩慢的化學(xué)變化,性能逐漸劣化,最終喪失絕緣能力.固體電介質(zhì)的化學(xué)變化通常使其電導(dǎo)增加,這會(huì)使介質(zhì)的溫度上升,因而電化學(xué)擊穿的最終形式是熱擊穿.溫度和電壓作用時(shí)間對電擊穿的影響小,對熱擊穿和電化學(xué)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(zhì)擊穿

純凈液體電介質(zhì)與含雜質(zhì)的工程液體電介質(zhì)的擊穿機(jī)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(zhì)分界面的放電現(xiàn)象稱為液體電介質(zhì)中的沿面放電.這種放電不僅使液體變質(zhì),而且放電產(chǎn)生的熱作用和劇烈的壓力變化可能使固體介質(zhì)內(nèi)產(chǎn)生氣泡.經(jīng)多次作用會(huì)使固體介質(zhì)出現(xiàn)分層,開裂現(xiàn)象,放電有可能在固體介質(zhì)內(nèi)發(fā)展,絕緣結(jié)構(gòu)的擊穿電壓因此下降.脈沖電壓下液體電介質(zhì)擊穿時(shí),常出現(xiàn)強(qiáng)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(nèi)臟結(jié)石的體外破碎.

氣體電介質(zhì)擊穿

在電場作用下氣體分子發(fā)生碰撞電離而導(dǎo)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(zhì)及狀態(tài)等.氣體介質(zhì)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(fù)電性氣體擊穿等.空氣是很好的氣體絕緣材料,電離場強(qiáng)和擊穿場強(qiáng)高,擊穿后能迅速恢復(fù)絕緣性能,且不燃,不爆,不老化,無腐蝕性,因而得到廣泛應(yīng)用.為提供高電壓輸電線或變電所的空氣間隙距離的設(shè)計(jì)依據(jù)（高壓輸電線應(yīng)離地面多高等）,需進(jìn)行長空氣間隙的工頻擊穿試驗(yàn).

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

介電強(qiáng)度，是材料抗高電壓而不產(chǎn)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(fā)生介電擊穿，以次測量介電強(qiáng)度。盡管所得的結(jié)果是以kv/mm為單位的，但并不表明與試樣的厚度無關(guān)。因此，只有在試樣厚度相同的條件下得到各種材料的數(shù)據(jù)才有可比性。

介電系數(shù)，是一個(gè)在電的位移和電場強(qiáng)度之間存在的比例常量。這一個(gè)常量在自由的空間（一個(gè)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(shù)可能差別很大，經(jīng)常遠(yuǎn)大于真空中的數(shù)值，其符號是eo。 在工程應(yīng)用中，介電系數(shù)時(shí)常在以相對介電系數(shù)的形式被表達(dá)，而不是絕對值。如果eo表現(xiàn)自由空間（是，8.85?10的-12次方F/m）的介電系數(shù)，而且e是在材料中的介電系數(shù)，則這個(gè)材料的相對介電系數(shù)（也叫介電常數(shù)）由下式給出：ε1=ε / εo=ε?1.13?10的11次方 很多不同的物質(zhì)的介電常數(shù)超過1。這些物質(zhì)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).

Instrument information for testing dielectric strength

The dielectric breakdown strength tester meets the requirements of GB1408.1-2006 and is mainly suitable for testing the breakdown strength and withstand time of solid insulation materials such as plastics, films, resins, mica, ceramics, glass, insulating paints, etc. under power frequency voltage or DC voltage; This instrument is controlled by a microcontroller and can quickly and accurately collect and process various data during the experimental process.

11. Durability of instrument operation: The instrument can operate continuously without the need for periodic shutdowns to protect it.
