電(dian)(dian)力系統中的試(shi)驗現(xian)場(chang)，由于(yu)停電(dian)(dian)檢修或者新建變電(dian)(dian)站(zhan)未能投運，都會造成現(xian)場(chang)試(shi)驗缺少試(shi)驗所用的工頻電(dian)(dian)源(yuan)，為滿(man)足現(xian)場(chang)試(shi)驗的需要，經常(chang)會使用發電(dian)(dian)機發電(dian)(dian)來供(gong)電(dian)(dian)，自帶(dai)

發電(dian)(dian)(dian)(dian)機發電(dian)(dian)(dian)(dian)往(wang)往(wang)發出的電(dian)(dian)(dian)(dian)壓不(bu)(bu)穩，頻(pin)率(lv)也(ye)不(bu)(bu)一定是(shi)純正50HZ正弦波(bo)，而許(xu)多試(shi)(shi)驗(yan)儀(yi)器對電(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)壓穩定性及頻(pin)率(lv)要(yao)(yao)求(qiu)較(jiao)高。電(dian)(dian)(dian)(dian)壓不(bu)(bu)穩，頻(pin)率(lv)不(bu)(bu)是(shi)50HZ等都會造成試(shi)(shi)驗(yan)結果不(bu)(bu)準確，甚至(zhi)儀(yi)器因(yin)電(dian)(dian)(dian)(dian)源(yuan)不(bu)(bu)穩被損(sun)壞。即使在變電(dian)(dian)(dian)(dian)站有電(dian)(dian)(dian)(dian)的情(qing)況下，有時現(xian)場取電(dian)(dian)(dian)(dian)也(ye)比較(jiao)麻煩，要(yao)(yao)布較(jiao)長電(dian)(dian)(dian)(dian)纜(lan)、需要(yao)(yao)接(jie)線、測試(shi)(shi)點(dian)離(li)取電(dian)(dian)(dian)(dian)點(dian)距(ju)離(li)較(jiao)遠、電(dian)(dian)(dian)(dian)纜(lan)不(bu)(bu)夠長以(yi)及現(xian)場工作電(dian)(dian)(dian)(dian)源(yuan)受各(ge)種(zhong)因(yin)素干擾造成嚴重的諧波(bo)等原因(yin)，同(tong)樣會影響工作效率(lv)及試(shi)(shi)驗(yan)的準確性。為此，我們為了適應電(dian)(dian)(dian)(dian)力系統現(xian)場實際工作的需要(yao)(yao)，研制(zhi)了一款(kuan)大容量(liang)便攜式工頻(pin)試(shi)(shi)驗(yan)電(dian)(dian)(dian)(dian)源(yuan)，本電(dian)(dian)(dian)(dian)源(yuan)采用大容量(liang)鋰電(dian)(dian)(dian)(dian)池組(zu)為供電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)源(yuan)，經逆變器轉換輸(shu)出純50HZ正弦波(bo)，電(dian)(dian)(dian)(dian)壓為穩定的交流220V，不(bu)(bu)但解決了現(xian)場試(shi)(shi)驗(yan)所需電(dian)(dian)(dian)(dian)源(yuan)，同(tong)時還可作為其(qi)他野(ye)外作業的備用電(dian)(dian)(dian)(dian)源(yuan)。

1、高性能、帶(dai)載能力強：本(ben)電(dian)源采用美國最先進逆變技(ji)術，供電(dian)質量高，適應各種負載，比(bi)如馬達、空調、電(dian)鉆(zhan)、日(ri)光(guang)燈、氣(qi)體燈等家(jia)電(dian)設(she)備(bei)，通信設(she)備(bei)，工業設(she)備(bei)。

2、高(gao)可靠(kao)：采用(yong)先進(jin)技術(shu)和(he)冗余(yu)設計，并配置工(gong)頻變壓器(qi),由CPU控制，選(xuan)用(yong)優質元器(qi)件精心制造，性(xing)能穩定，可靠(kao)性(xing)高(gao)。

3、保護完(wan)善：具(ju)有輸入過(guo)欠壓保護；輸出過(guo)載(zai)、過(guo)流、短路保護；整機過(guo)溫保護等，可以抗拒大電流啟動負載(zai)沖擊。

4、界面友好：LCD/LED顯示:工(gong)作狀態、輸出電壓，電池電壓、頻率、負載(zai)率、故(gu)障(zhang)(zhang)等(deng)(deng)信息(xi)清晰明(ming)了；并且(qie)有(you)聲光(guang)故(gu)障(zhang)(zhang)報警、指示故(gu)障(zhang)(zhang)等(deng)(deng)功能。

5、 操作(zuo)簡單：智能開關機，自動化程度高，操作(zuo)方便。

6、 結構(gou)簡(jian)潔：機(ji)內功能(neng)部件采用(yong)模塊化設計，結構(gou)簡(jian)潔，維護方便。

7、 攜(xie)帶方便：拉桿箱(xiang)設計，便于現(xian)場使(shi)用。

8、 效率高,節(jie)能(neng)：空載電流(liu)小(xiao),在(zai)沒(mei)有負載情況下節(jie)約能(neng)源(yuan)。

9、智(zhi)能電(dian)(dian)池(chi)管(guan)理：智(zhi)能電(dian)(dian)池(chi)監(jian)測管(guan)理系(xi)統，加強電(dian)(dian)池(chi)監(jian)測，延長電(dian)(dian)池(chi)壽命和利用率。直流供電(dian)(dian)電(dian)(dian)路下限保(bao)護(hu)設計，當直流電(dian)(dian)源低于(yu)保(bao)護(hu)電(dian)(dian)壓，逆(ni)變器將自(zi)動關閉。
