絕緣電氣強(qiáng)度擊穿電壓試驗(yàn)儀

使電介質(zhì)擊穿的電壓。電介質(zhì)在足夠強(qiáng)的電場作用下將失去其介電性能成為導(dǎo)體,稱為電介質(zhì)擊穿,所對(duì)應(yīng)的電壓稱為擊穿電壓。

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.
