擊穿電壓是使電介質(zhì)擊穿的電壓，電介質(zhì)在足夠強(qiáng)的電場(chǎng)作用下將失去其介電性能成為導(dǎo)體，稱(chēng)為電介質(zhì)擊穿，所對(duì)應(yīng)的電壓稱(chēng)為擊穿電壓。電介質(zhì)擊穿時(shí)的電場(chǎng)強(qiáng)度叫擊穿場(chǎng)強(qiáng)。

在強(qiáng)電場(chǎng)作用下，固體電介質(zhì)喪失電絕緣能力而由絕緣狀態(tài)突變?yōu)榱紝?dǎo)電狀態(tài)。導(dǎo)致?lián)舸┑?nbsp;低臨界電壓稱(chēng)為擊穿電壓，在均勻電場(chǎng)中，擊穿電壓與固體電介質(zhì)厚度之比稱(chēng)為擊穿電場(chǎng)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(chǎng)中，擊穿電壓與擊穿處固體電介質(zhì)厚度之比稱(chēng)為平均擊穿場(chǎng)強(qiáng)，它低于均勻電場(chǎng)中固體電介質(zhì)的介電強(qiáng)度。不同電介質(zhì)在相同溫度下，其擊穿場(chǎng)強(qiáng)不同。當(dāng)電容器介質(zhì)和兩極板的距離d一定后，由U1-U2=Ed知，擊穿場(chǎng)強(qiáng)決定了擊穿電壓。

擊穿電壓也是評(píng)定絕緣油電氣性能的一項(xiàng)指標(biāo)，可用來(lái)判斷絕緣油含水和其他懸浮物污染的程度，以及對(duì)注入設(shè)備前油品干燥和過(guò)濾程度的檢驗(yàn)。對(duì)清凈干燥的油施加一個(gè)逐漸升高的電壓時(shí)，在電壓的負(fù)  會(huì)發(fā)射擊電子。當(dāng)電子具有足夠能量時(shí)，可以使油分子微化離解。

于是整個(gè)離解過(guò)程隨電壓升高而加強(qiáng)，當(dāng)達(dá)到某一個(gè)電壓后，會(huì)產(chǎn)生大量傳導(dǎo)電流而形成電弧，這種現(xiàn)象被稱(chēng)為擊穿。若油中有水或固體物存在時(shí)，則會(huì)使擊穿電壓變小，這是由于水和固體物的導(dǎo)電性均比油大之緣故。運(yùn)行中油的擊穿電壓低是變壓器工作危險(xiǎn)的信號(hào)。

The breakdown voltage is the voltage that causes a dielectric to break through. When a dielectric loses its dielectric properties and becomes a conductor under a strong enough electric field, it is called dielectric breakdown, and the corresponding voltage is called breakdown voltage. The electric field strength at the time of dielectric breakdown is called the breakdown field strength.

Under the action of a strong electric field, solid dielectrics lose their electrical insulation ability and transition from an insulating state to a well conductive state. The minimum critical voltage that causes breakdown is called the breakdown voltage. In a uniform electric field, the ratio of the breakdown voltage to the thickness of the solid dielectric is called the breakdown electric field strength, which reflects the dielectric strength of the solid dielectric itself.

In an uneven electric field, the ratio of breakdown voltage to the thickness of the solid dielectric at the breakdown point is called the average breakdown field strength, which is lower than the dielectric strength of the solid dielectric in a uniform electric field. Different dielectrics have different breakdown field strengths at the same temperature. When the distance d between the dielectric of the capacitor and the two plates is constant, the breakdown voltage is determined by the breakdown field strength determined by U1-U2=Ed.

The breakdown voltage is also an indicator for evaluating the electrical performance of insulating oil, which can be used to determine the degree of water content and other suspended matter pollution in the insulating oil, as well as to inspect the degree of drying and filtration of the oil before injection into the equipment. When a gradually increasing voltage is applied to clean and dry oil, electrons will be emitted at the negative end of the voltage. When electrons have sufficient energy, they can cause oil molecules to undergo micro ionization and dissociation.

So the entire dissociation process strengthens with the increase of voltage. When a certain voltage is reached, a large amount of conductive current is generated, forming an arc, which is called breakdown. If there is water or solid in the oil, it will reduce the breakdown voltage because the conductivity of water and solid is higher than that of oil. The low breakdown voltage of oil during operation is a signal of the danger of transformer operation.

電極和試樣

金屬電極應(yīng)始終保持光滑、清潔和無(wú)缺陷。

注1：當(dāng)對(duì)薄試樣進(jìn)行試驗(yàn)時(shí)，電極的維護(hù)格外重要。為了在擊穿時(shí)盡量減小電極損傷，優(yōu)先采用不銹鋼電極。

接到電極上的導(dǎo)線(xiàn)即不應(yīng)使得電極傾斜或其他移動(dòng)或使得試樣上壓力變化，也不應(yīng)使得試樣周?chē)碾妶?chǎng)分布受到顯著影響。

注2：試驗(yàn)非常薄的薄膜（例如：<μm厚)時(shí),這些材料的產(chǎn)品標(biāo)準(zhǔn)應(yīng)規(guī)定所用的電極、操作的具體程序和試樣的制備方法。

電氣擊穿electric breakdown

試樣承受電應(yīng)力作用時(shí)，其絕緣性能?chē)?yán)重?fù)p失，由此引起的試驗(yàn)回路電流促使相應(yīng)的回路斷路器動(dòng)作。

注：擊穿通常是由試樣和電極周?chē)臍怏w或液體媒質(zhì)中的局部放電引起，并使得較小電極（或等徑兩電極）邊緣的試樣遭到破壞。

Electrodes and specimens

Metal electrodes should always be smooth, clean, and defect free.

Note 1: When testing thin specimens, electrode maintenance is particularly important. In order to minimize electrode damage during breakdown, stainless steel electrodes are preferred.

The wire connected to the electrode should not tilt or move the electrode or cause pressure changes on the sample, nor should it significantly affect the distribution of the electric field around the sample.

Note 2: Test very thin films (e.g.:< μ When the thickness is m, the product standards for these materials should specify the electrodes used, the specific procedures for operation, and the preparation method for the samples.

Electrical breakdown

When the sample is subjected to electrical stress, its insulation performance is severely damaged, and the resulting test circuit current drives the corresponding circuit breaker to operate.

Note: Breakthrough is usually caused by partial discharge in the gas or liquid medium around the sample and electrode, causing damage to the sample at the edge of the smaller electrode (or equal diameter two electrodes).
