一、產品簡介(jie)

便攜式變頻串聯諧振交流耐壓試驗裝置主要由變頻控制器，勵磁變壓器，高壓電抗器，高壓分壓器等組成。變頻控制器又分兩大類，20KW及以上為控制臺 式，20KW以下為便攜箱式；它由控制器和濾波器組成。變頻控制器主要作用是把幅值和頻率都固定的380V或200V工頻正弦交流電轉變為幅值和頻率可調 的正弦波。并為整套設備提供電源。勵磁變壓器的作用是將變頻電源輸出的電壓升到合適的試驗電壓。

2、友好的(de)人機接口：的(de)DSP 顯示平臺，大容(rong)量的(de)數據存儲器，8寸大屏幕LCD 顯示；豐(feng)富的(de)幫(bang)助(zhu)應用信息，幫(bang)助(zhu)你現(xian)場分析試(shi)驗發生(sheng)保護動作時(shi)可能出現(xian)的(de)問題(ti)；（具(ju)有調頻(pin)時(shi)顯示頻(pin)率(lv)－電壓波(bo)形曲(qu)線，直(zhi)觀的(de)觀察到是否(fou)尋找(zhao)到諧振(zhen)點(dian)；）

3、*的結構設計(ji)(ji)：調(diao)頻電(dian)源控(kong)制(zhi)箱的接入和輸出采(cai)用插(cha)接和螺絲連(lian)接兩種(zhong)方(fang)式，安全、方(fang)便、可靠、美(mei)觀精(jing)致(zhi)；電(dian)抗器采(cai)用*的環氧澆注工藝，防潮防顛震(zhen)；整體(ti)色(se)彩(cai)和外型(xing)由專業的設計(ji)(ji)公司(si)專門設計(ji)(ji)，美(mei)觀大方(fang)。

4、系(xi)統人機交(jiao)互界面友好:試(shi)驗參數設置、試(shi)驗控(kong)制、試(shi)驗結果(guo)等同(tong)屏(ping)顯(xian)示(shi)(shi)，直(zhi)觀清晰，并(bing)具有(you)自動計時(shi)及操(cao)作(zuo)提示(shi)(shi)功(gong)能。全觸摸(mo)屏(ping)操(cao)作(zuo)及顯(xian)示(shi)(shi)，具備試(shi)驗數據保(bao)存(cun)和查(cha)詢功(gong)能 。

5、操作箱在上電(dian)后合上“電(dian)源開關”， 液(ye)晶(jing)點亮(liang)顯示。

注意：儀器(qi)(qi)兩側開孔處的風(feng)扇在運(yun)行則表示表示儀器(qi)(qi)內(nei)部功率器(qi)(qi)件正常(chang)工作。否則表示儀器(qi)(qi)內(nei)部過熱(re)或上次試(shi)驗時沒有(you)復位。此時應該切斷(duan)電源，將儀器(qi)(qi)置于通風(feng)處靜置1小時左右，待內(nei)部適當降(jiang)低溫度后再啟動(dong)電源。

當(dang)風扇經常性的不啟動(dong)時(shi)，建(jian)議(yi)立(li)即與廠家聯系。

當設備出(chu)現不(bu)可恢(hui)復性(xing)故障時，請不(bu)要自行拆卸(xie)儀器。
