一、產品(pin)概述：

    晟皋電氣打造(zao)的(de)(de)(de) KD-3000GIS交流耐壓(ya)(ya)(ya)試(shi)驗(yan)儀(變(bian)頻串(chuan)聯諧(xie)振試(shi)驗(yan)裝置(zhi))廣泛(fan)應用(yong)于電力、冶金、石油、化工、等(deng)行(xing)業，適(shi)用(yong)于大容(rong)量、高(gao)電壓(ya)(ya)(ya)的(de)(de)(de)電容(rong)性(xing)試(shi)品，如(ru)發(fa)電機、變(bian)壓(ya)(ya)(ya)器、GIS、高(gao)壓(ya)(ya)(ya)交聯電纜、互感器、套管等(deng)的(de)(de)(de)交接實驗(yan)和(he)(he)預防(fang)性(xing)試(shi)驗(yan)。本公司在(zai)變(bian)頻串(chuan)聯諧(xie)振高(gao)壓(ya)(ya)(ya)試(shi)驗(yan)領域自(zi)主的(de)(de)(de)變(bian)頻、調壓(ya)(ya)(ya)軟件技術，**于國內(nei)高(gao)壓(ya)(ya)(ya)試(shi)驗(yan)行(xing)業，利用(yong)這一(yi)技術采(cai)用(yong)16位精細變(bian)頻、10KHZ載(zai)波頻率(lv)、SPWM和(he)(he)進口原(yuan)裝IPM整體模塊設(she)計(ji)、制造(zao)的(de)(de)(de)變(bian)頻串(chuan)并聯諧(xie)振成套試(shi)驗(yan)裝置(zhi)，完全(quan)符合國家有關(guan)高(gao)壓(ya)(ya)(ya)實驗(yan)的(de)(de)(de)規程和(he)(he)要(yao)求。

二、工作(zuo)原理

     KD-3000GIS交流耐壓(ya)試(shi)(shi)(shi)驗(yan)儀運用串(chuan)并聯諧(xie)(xie)振(zhen)的(de)(de)(de)原理，通過(guo)(guo)調節(jie)變頻(pin)(pin)控制(zhi)器(qi)(qi)的(de)(de)(de)輸(shu)出頻(pin)(pin)率(lv)，使(shi)得回(hui)路中的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)抗器(qi)(qi)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)感L和(he)試(shi)(shi)(shi)品(pin)(pin)電(dian)(dian)(dian)(dian)(dian)容C發生諧(xie)(xie)振(zhen)，諧(xie)(xie)振(zhen)電(dian)(dian)(dian)(dian)(dian)壓(ya)即為試(shi)(shi)(shi)品(pin)(pin)上所(suo)加(jia)電(dian)(dian)(dian)(dian)(dian)壓(ya)。通過(guo)(guo)調頻(pin)(pin)控制(zhi)器(qi)(qi)提供供電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)源，試(shi)(shi)(shi)驗(yan)電(dian)(dian)(dian)(dian)(dian)壓(ya)由勵磁變壓(ya)器(qi)(qi)經(jing)過(guo)(guo)初步(bu)升壓(ya)后(hou)，使(shi)高(gao)電(dian)(dian)(dian)(dian)(dian)壓(ya)加(jia)在(zai)電(dian)(dian)(dian)(dian)(dian)抗器(qi)(qi)L和(he)被試(shi)(shi)(shi)品(pin)(pin)CX上，通過(guo)(guo)改變調頻(pin)(pin)控制(zhi)器(qi)(qi)的(de)(de)(de)輸(shu)出頻(pin)(pin)率(lv)，使(shi)回(hui)路處于串(chuan)聯諧(xie)(xie)振(zhen)狀態；回(hui)路的(de)(de)(de)諧(xie)(xie)振(zhen)頻(pin)(pin)率(lv)取決于被試(shi)(shi)(shi)品(pin)(pin)電(dian)(dian)(dian)(dian)(dian)容CX和(he)電(dian)(dian)(dian)(dian)(dian)抗器(qi)(qi)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)感L，調節(jie)變頻(pin)(pin)控制(zhi)器(qi)(qi)的(de)(de)(de)輸(shu)出電(dian)(dian)(dian)(dian)(dian)壓(ya)，使(shi)試(shi)(shi)(shi)品(pin)(pin)上高(gao)壓(ya)達到所(suo)需要的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)值。
