電壓擊穿試驗(yàn)儀耐電壓擊穿強(qiáng)度試驗(yàn)儀
電壓擊穿試驗(yàn)儀整機(jī)組成:
1、升壓部件:由調(diào)壓器和高壓變壓器組成0~50KV的升壓部分。
2、動部件:由步進(jìn)電機(jī)均勻調(diào)節(jié)調(diào)壓器使加給高壓變壓器的電壓變化。
3、檢測部件:由集成電路組成的測量電路。通過信號線把檢測的模擬信號和開關(guān)信號傳給計(jì)算機(jī)。
4、計(jì)算機(jī)軟件:通過智能電路把由檢測設(shè)備采集的測控信號傳給計(jì)算機(jī)。計(jì)算機(jī)根據(jù)采集的信息控制設(shè)備運(yùn)行并處理試驗(yàn)結(jié)果。
5、試驗(yàn)電極:根據(jù)國家標(biāo)準(zhǔn)(1408.1-2006)隨設(shè)備提供三個(gè)電極,具體規(guī)格為:Ф25mm×25mm兩個(gè);Ф75mm×25mm一個(gè)。
Voltage breakdown tester:
1, boost parts: voltage regulator and high voltage transformer composed of 0 ~ 50KV boost part.
2, moving parts: step by step motor to adjust the voltage regulator to make the transformer voltage changes.
3, detection components: circuit composed of integrated circuit. Analog signals and switch signals are transmitted to the computer by a signal line.
4, computer software: through the inligent circuit to detect the signal collected by the test equipment to the computer. The computer controls the operation of the equipment according to the collected information and processes the test results.
5, the test electrode: according to the national standard (1408.1-2006) provided with the equipment of three electrodes, specification: diameter of 25mm * 25MM two * 25MM with a 75mm.
電壓擊穿試驗(yàn)儀定義
在固體電介質(zhì)中發(fā)生破壞性放電時(shí),稱為擊穿。擊穿時(shí),在固體電介質(zhì)中留下痕跡,使固體電介質(zhì)*失去絕緣性能。如絕緣紙板擊穿時(shí),會在紙板上留下一個(gè)孔??梢姄舸┻@個(gè)詞用于固體電介質(zhì)中。
電壓擊穿試驗(yàn)儀概念
擊穿(breakdown)---絕緣物質(zhì)在電場的作用下發(fā)生劇烈放電或?qū)щ姷默F(xiàn)象叫擊穿。 例如,平常我們使用的驗(yàn)電筆中的氖管發(fā)光,就是氖管兩端的電壓超過70V而被擊穿;電容器兩端電壓過高,會使夾在其中的電介質(zhì)擊穿。
