絕緣電氣強度擊穿電壓試驗儀
使電介質擊穿的電壓。電介質在足夠強的電場作用下將失去其介電性能成為導體,稱為電介質擊穿,所對應的電壓稱為擊穿電壓。
電介質擊穿時的電場強度叫擊穿場強。不同電介質在相同溫度下,其擊穿場強不同。當電容器介質和兩極板的距離d一定后,由U1-U2=Ed知,擊穿場強決定了擊穿電壓。擊穿場強通常又稱為電介質的介電強度。
提高電容器的耐壓能力起關鍵作用的是電介質的介電強度。附表為各種電介質的相對介電常量εr和介電強度。電介質εr擊穿場強,×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.
