簡介：PAGE1高電壓技術課程設計高電壓技術課程設計沖擊電壓發(fā)生器的設計班級姓名學號指導老師PAGE3二、沖擊電壓發(fā)生器的功用及原理二、沖擊電壓發(fā)生器的功用及原理沖擊電壓發(fā)生器是一種產(chǎn)生脈沖波的高電壓發(fā)生裝置。原先它只被用于研究電力設備遭受大氣過電壓（雷擊）時的絕緣性能，近年來又被用于研究電力設備遭受操作過電壓時的絕緣性能。所以對沖擊電壓發(fā)生器的要求，不僅能產(chǎn)生出現(xiàn)在電力設備上的雷電波形，還能產(chǎn)生操作過電壓波形。沖擊電壓的破壞作用不僅決定于幅值，還與波形陡度有關，對某些設備要采用截斷波來進行試驗。沖擊電壓發(fā)生器要滿足兩個要求首先要能輸出幾十萬到幾百萬伏的電壓，同時這電壓要具有一定的波形。它的原理圖如圖2。實驗變壓器T和高壓硅堆D構成整流電源，經(jīng)過保護電阻R及充電電阻R向主電容器C1C4充電，充電到U，出現(xiàn)在球隙G1G4上的電位差也為U，若事先把球間隙距離調到稍大于U，球隙不會放電。當需要使沖擊機動作時，可向點火球隙的針極送去一脈沖電壓，針極和球皮只見產(chǎn)生一小火花，引起點火球隙放電，于是電容器C1的上極板經(jīng)G1接地，點1電位由地電位變?yōu)閁。電容器C1與C2間有充電電阻R隔開，R比較大，在G1放電瞬間，點2和點3電位不可能突然改變，點3電位仍為U，中間球隙G2上的電位差突然升到2U，G2馬上放電，于是點2電位變?yōu)?U。同理，G3，G4也跟著放電，電容器C1C4串聯(lián)起來了，最后球隙G0也放電，此時輸出電壓為C1C4上電壓的總和，即4U。上述一系列過程可被概括為“電容器并聯(lián)充電，而后串聯(lián)放電”。
