揚州志力電氣在發電機交(jiao)流(liu)耐壓(ya)諧(xie)振裝(zhuang)置方(fang)面自行開發的調頻(pin)、調壓(ya)軟(ruan)件技術(shu)，先進于國內高(gao)壓(ya)試驗(yan)行業(ye)，利用這一技術(shu)采用16位(wei)精(jing)細調頻(pin)、10KHz載波頻(pin)率、SPWM和進口原裝(zhuang)IPM整體模塊設計，制造的調頻(pin)串并(bing)聯諧(xie)振交(jiao)流(liu)耐壓(ya)試驗(yan)裝(zhuang)置，*符(fu)合國家有關高(gao)壓(ya)試驗(yan)的規程和要求。

交流(liu)耐壓(ya)調頻諧振試驗裝置廣泛(fan)應(ying)用于電(dian)(dian)力(li)、冶金、石油、化工等行業(ye)，適(shi)用于大容(rong)量、高(gao)電(dian)(dian)壓(ya)的(de)電(dian)(dian)容(rong)性(xing)試品，如(ru)發電(dian)(dian)機、變壓(ya)器、GIS、高(gao)壓(ya)交聯電(dian)(dian)纜(lan)、互(hu)感器、套管等的(de)交接試驗和預防(fang)性(xing)試驗。

交流耐壓(ya)調(diao)頻諧振(zhen)試驗(yan)裝置工作原理

電(dian)(dian)抗(kang)器L和被(bei)試(shi)品電(dian)(dian)容(rong)C組成的串聯(lian)諧振(zhen)都有(you)一個(ge)固定的諧振(zhen)頻(pin)(pin)率F=1/(2π√L·C)當試(shi)驗(yan)頻(pin)(pin)率等于(yu)這個(ge)頻(pin)(pin)率時(shi)，該(gai)電(dian)(dian)路(lu)發生諧振(zhen)。通過(guo)這個(ge)原(yuan)理，由調(diao)頻(pin)(pin)電(dian)(dian)源提供電(dian)(dian)源送給(gei)勵磁變壓(ya)(ya)(ya)器，經(jing)過(guo)勵磁變壓(ya)(ya)(ya)器變壓(ya)(ya)(ya)成中壓(ya)(ya)(ya)加上(shang)L和被(bei)試(shi)品電(dian)(dian)容(rong)C上(shang)。通過(guo)改變調(diao)頻(pin)(pin)電(dian)(dian)源輸(shu)出頻(pin)(pin)率，使回路(lu)處于(yu)串聯(lian)諧振(zhen)狀(zhuang)態，再調(diao)節(jie)調(diao)頻(pin)(pin)電(dian)(dian)源輸(shu)出電(dian)(dian)壓(ya)(ya)(ya)，使試(shi)品上(shang)電(dian)(dian)壓(ya)(ya)(ya)達到(dao)所需要的電(dian)(dian)壓(ya)(ya)(ya)值。

交流耐壓調頻諧振試驗裝置成套裝置構成

調頻電(dian)源——既可(ke)改(gai)變其輸(shu)出(chu)頻率，又可(ke)改(gai)變其輸(shu)出(chu)電(dian)壓。

勵磁(ci)變(bian)壓器——起耦合(he)信號(hao)及電(dian)壓變(bian)換(huan)的作用，并按自身變(bian)化來提升電(dian)壓。

電抗器——與被試品串聯，構(gou)成LC串聯諧振(zhen)電路。

電(dian)(dian)容分壓器——測量(liang)被試品上的電(dian)(dian)壓，并(bing)作為采樣信號(hao)反饋給(gei)調(diao)頻電(dian)(dian)源(yuan)。

補(bu)(bu)償電容(rong)器——補(bu)(bu)償小電容(rong)量被試品、調(diao)整被試品頻率。
