產品簡介

35KV電纜交流耐壓試驗裝置是運用(yong)(yong)串(chuan)(chuan)聯(lian)諧(xie)振(zhen)原理，利用(yong)(yong)勵磁(ci)變壓(ya)器激發串(chuan)(chuan)聯(lian)諧(xie)振(zhen)回(hui)路，調(diao)節變頻控制(zhi)器的輸出頻率，使回(hui)路電(dian)(dian)感L和試(shi)(shi)品C串(chuan)(chuan)聯(lian)諧(xie)振(zhen)，諧(xie)振(zhen)電(dian)(dian)壓(ya)即為加到試(shi)(shi)品上電(dian)(dian)壓(ya)。變頻諧(xie)振(zhen)試(shi)(shi)驗裝置廣(guang)泛用(yong)(yong)于電(dian)(dian)力、冶金(jin)、石油、化工等(deng)行(xing)業(ye)，適用(yong)(yong)于大容(rong)(rong)量，高電(dian)(dian)壓(ya)的電(dian)(dian)容(rong)(rong)性(xing)試(shi)(shi)品的交接(jie)和預防性(xing)試(shi)(shi)驗。

串(chuan)聯諧(xie)(xie)振耐壓(ya)裝置主要(yao)由變(bian)(bian)頻(pin)控(kong)制(zhi)器(qi)(qi)，勵磁變(bian)(bian)壓(ya)器(qi)(qi)，高(gao)壓(ya)電(dian)(dian)(dian)(dian)抗(kang)器(qi)(qi)，高(gao)壓(ya)分(fen)壓(ya)器(qi)(qi)等(deng)組(zu)成(cheng)。變(bian)(bian)頻(pin)控(kong)制(zhi)器(qi)(qi)又分(fen)兩(liang)大(da)類，20KW及以上為(wei)(wei)(wei)控(kong)制(zhi)臺(tai)式，20KW以下為(wei)(wei)(wei)便攜(xie)箱(xiang)式；它(ta)由控(kong)制(zhi)器(qi)(qi)和(he)(he)濾波器(qi)(qi)組(zu)成(cheng)。變(bian)(bian)頻(pin)控(kong)制(zhi)器(qi)(qi)主要(yao)作(zuo)用是(shi)(shi)把幅值和(he)(he)頻(pin)率都固(gu)定(ding)的(de)380V或200V工頻(pin)正弦交流電(dian)(dian)(dian)(dian)轉變(bian)(bian)為(wei)(wei)(wei)幅值和(he)(he)頻(pin)率可調的(de)正弦波。并為(wei)(wei)(wei)整套設備(bei)提供電(dian)(dian)(dian)(dian)源。勵磁變(bian)(bian)壓(ya)器(qi)(qi)的(de)作(zuo)用是(shi)(shi)將變(bian)(bian)頻(pin)電(dian)(dian)(dian)(dian)源輸出的(de)電(dian)(dian)(dian)(dian)壓(ya)升到(dao)合(he)適(shi)的(de)試(shi)驗電(dian)(dian)(dian)(dian)壓(ya)。高(gao)壓(ya)電(dian)(dian)(dian)(dian)抗(kang)器(qi)(qi)L是(shi)(shi)諧(xie)(xie)振回路重要(yao)部件，當電(dian)(dian)(dian)(dian)源頻(pin)率等(deng)于1/(2π√LCX)時，它(ta)與被試(shi)品CX發生串(chuan)聯諧(xie)(xie)振。

變頻串聯諧振(zhen)試(shi)驗(yan)裝置適(shi)(shi)用(yong)于(yu)10KV、35KV、110KV、220KV、500KV聚己烯電力電纜交流耐壓(ya)試(shi)驗(yan)。適(shi)(shi)用(yong)于(yu)60KV、220KV，500KVGIS交流耐壓(ya)試(shi)驗(yan)。適(shi)(shi)用(yong)于(yu)大(da)型變壓(ya)器，發(fa)電機組工頻耐壓(ya)試(shi)驗(yan)；電力變壓(ya)器感應耐壓(ya)試(shi)驗(yan)；接地電阻測量。

產品特征

1、穩(wen)定性、可(ke)靠(kao)性高。系(xi)統(tong)采用進口(kou)功(gong)率(lv)元件作為功(gong)率(lv)變換(huan)的(de)核心，電(dian)壓(ya)輸出和頻率(lv)輸出穩(wen)定，電(dian)磁兼容設計(ji)合理，保(bao)護(hu)功(gong)能完善，經過多次高壓(ya)直(zhi)接對(dui)地(di)短路的(de)測試(shi)，系(xi)統(tong)仍然保(bao)持完好，同時系(xi)統(tong)也有很強的(de)過載(zai)能力。

2、自(zi)(zi)動調諧(xie)(xie)(xie)功能強大。系(xi)統(tong)自(zi)(zi)動調諧(xie)(xie)(xie)時，從30Hz到300Hz自(zi)(zi)動掃(sao)頻(pin)，顯示掃(sao)頻(pin)曲線，用戶(hu)能直觀地看到系(xi)統(tong)調諧(xie)(xie)(xie)過程；掃(sao)頻(pin)完成后，系(xi)統(tong)根據掃(sao)頻(pin)初步找到的諧(xie)(xie)(xie)振頻(pin)點，在(zai)其±5Hz范圍(wei)內以0.01Hz為(wei)分辨率(lv)進行(xing)頻(pin)率(lv)細掃(sao)，zui后*鎖定諧(xie)(xie)(xie)振頻(pin)率(lv)。

3、35KV電纜交流耐壓試驗裝置支持多種試驗(yan)模(mo)式。系統支持"自動(dong)調諧(xie)＋手(shou)(shou)(shou)動(dong)調壓(ya)(ya)(ya)"，"自動(dong)調諧(xie)＋自動(dong)調壓(ya)(ya)(ya)"，"手(shou)(shou)(shou)動(dong)調諧(xie)＋手(shou)(shou)(shou)動(dong)調壓(ya)(ya)(ya)"等試驗(yan)模(mo)式，推薦使用(yong)"自動(dong)調諧(xie)＋手(shou)(shou)(shou)動(dong)調壓(ya)(ya)(ya)"模(mo)式，既能快速找到諧(xie)振(zhen)點(dian)，又能通過手(shou)(shou)(shou)動(dong)調壓(ya)(ya)(ya)控(kong)制(zhi)試驗(yan)過程(cheng)，安全(quan)性(xing)更高。

4、系統人機交互界面友好。試驗(yan)(yan)參數(shu)設置、試驗(yan)(yan)控制、試驗(yan)(yan)結(jie)果等同(tong)屏顯(xian)示，直觀清(qing)晰(xi)，并具(ju)有自動計時及操(cao)(cao)作提示功能。全觸(chu)摸屏操(cao)(cao)作及顯(xian)示，具(ju)備試驗(yan)(yan)數(shu)據保存和(he)查詢。

5、保(bao)(bao)護(hu)功能(neng)完善。具備零位保(bao)(bao)護(hu)(電壓輸出(chu)控制旋(xuan)鈕不在零位時(shi)，禁止系(xi)統啟動)，過壓保(bao)(bao)護(hu)，過流(liu)保(bao)(bao)護(hu)，閃(shan)絡(luo)保(bao)(bao)護(hu)等功能(neng)，保(bao)(bao)證了系(xi)統的可靠性
