使電介質(zhì)擊穿的電壓。電介質(zhì)在足夠強的電場(chǎng)作用下將失去其介電性能成為導體,稱(chēng)為電介質(zhì)擊穿,所對應的電壓稱(chēng)為擊穿電壓。

電介質(zhì)擊穿時(shí)的電場(chǎng)強度叫擊穿場(chǎng)強。不同電介質(zhì)在相同溫度下,其擊穿場(chǎng)強不同。當電容器介質(zhì)和兩極板的距離d一定后,由U1-U2=Ed知,擊穿場(chǎng)強決定了擊穿電壓。擊穿場(chǎng)強通常又稱(chēng)為電介質(zhì)的介電強度。

提高電容器的耐壓能力起關(guān)鍵作用的是電介質(zhì)的介電強度。附表為各種電介質(zhì)的相對介電常量εr和介電強度。電介質(zhì)εr擊穿場(chǎng)強,×106/（V·m-1）

Insulation dielectric strength tester breakdown voltage
 
The dielectric breakdown voltage. Dielectric under the action of electric field in a strong enough will lose its dielectric properties become the conductor, called the dielectric breakdown, the corresponding voltage is called the breakdown voltage.
 
When the dielectric breakdown electric field intensity is called breakdown voltage. Different dielectric under the same temperature, the breakdown voltage is different. Capacitor medium and the plates, after a certain distance d by U1 - U2 = Ed, breakdown voltage determines the breakdown voltage. Dielectric breakdown voltage is often called the dielectric.
