絕緣電氣強(qiáng)度擊穿電壓試驗(yàn)儀結(jié)構(gòu)原理及性能特點(diǎn)：
1、主要由升壓系統(tǒng)、測量系統(tǒng)、A/D轉(zhuǎn)換器、放電系統(tǒng)、電極、油箱、電極定位架、計(jì)算機(jī)數(shù)據(jù)處理系統(tǒng)、軟件等組成；
2、計(jì)算機(jī)---A/D轉(zhuǎn)換器---測量控制系統(tǒng)---調(diào)壓裝置---升壓變壓器---試樣；
3、高壓變壓器主要產(chǎn)生試樣所需的直流電壓；
4、調(diào)壓器用于調(diào)節(jié)升壓變壓器輸入端電壓以產(chǎn)生高壓所需的輸入電壓；
5、電壓測量主要是從高壓變壓器測量端測量，高壓變壓器測量端和高壓端是線性的；
6、放電系統(tǒng)在試驗(yàn)做完以后放電，以免產(chǎn)生放電對人身的危害；（當(dāng)試驗(yàn)結(jié)束后，機(jī)器部件仍可能存在殘留的高電壓，此殘留電壓足以對人產(chǎn)生致命的傷害，配備此棒，完好的解決此安全隱患）。

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,所對應(yīng)的電壓稱為擊穿電壓。
電介質(zhì)擊穿時(shí)的電場強(qiáng)度叫擊穿場強(qiáng)。不同電介質(zhì)在相同溫度下,其擊穿場強(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,擊穿場強(qiáng)決定了擊穿電壓。擊穿場強(qiáng)通常又稱為電介質(zhì)的介電強(qiáng)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(qiáng)度。附表為各種電介質(zhì)的相對介電常量εr和介電強(qiáng)度。電介質(zhì)εr擊穿場強(qiáng),×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.
