绝缘电气强度击穿电压试验仪
使电介质击穿的电压。电介质在足够强的电场作用下将失去其介电性能成为导体,称为电介质击穿,所对应的电压称为击穿电压。
电介质击穿时的电场强度叫击穿场强。不同电介质在相同温度下,其击穿场强不同。当电容器介质和两极板的距离d一定后,由U1-U2=Ed知,击穿场强决定了击穿电压。击穿场强通常又称为电介质的介电强度。
提高电容器的耐压能力起关键作用的是电介质的介电强度。附表为各种电介质的相对介电常量εr和介电强度。电介质εr击穿场强,×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.
