電力系(xi)統中的試(shi)(shi)驗現(xian)場，由于停電檢修(xiu)或者新建變電站未能投運，都會(hui)造成現(xian)場試(shi)(shi)驗缺(que)少試(shi)(shi)驗所用(yong)的工頻電源，為滿足現(xian)場試(shi)(shi)驗的需要，經常會(hui)使用(yong)發(fa)電機(ji)發(fa)電來供電，自帶

發電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機發電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)往(wang)往(wang)發出的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)不(bu)穩，頻率(lv)(lv)也(ye)不(bu)一定是純(chun)正50HZ正弦(xian)波，而許多試(shi)(shi)驗(yan)(yan)儀(yi)(yi)器(qi)對(dui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)穩定性及頻率(lv)(lv)要(yao)(yao)求較(jiao)高。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)不(bu)穩，頻率(lv)(lv)不(bu)是50HZ等(deng)都會造(zao)成(cheng)試(shi)(shi)驗(yan)(yan)結果不(bu)準確，甚至儀(yi)(yi)器(qi)因電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)不(bu)穩被損壞。即使在變電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)站有電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)情況下，有時現(xian)場取電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)也(ye)比(bi)較(jiao)麻煩，要(yao)(yao)布較(jiao)長電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜、需要(yao)(yao)接線、測試(shi)(shi)點離取電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)點距離較(jiao)遠、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜不(bu)夠長以(yi)及現(xian)場工(gong)作電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)受各種(zhong)因素干擾造(zao)成(cheng)嚴重的(de)諧波等(deng)原因，同樣會影響工(gong)作效率(lv)(lv)及試(shi)(shi)驗(yan)(yan)的(de)準確性。為(wei)此，我(wo)們為(wei)了(le)(le)適應電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)系統現(xian)場實際工(gong)作的(de)需要(yao)(yao)，研制(zhi)了(le)(le)一款大容(rong)量(liang)便攜式工(gong)頻試(shi)(shi)驗(yan)(yan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)，本電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)采用(yong)大容(rong)量(liang)鋰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池組(zu)為(wei)供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)，經(jing)逆變器(qi)轉換輸出純(chun)50HZ正弦(xian)波，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)為(wei)穩定的(de)交流220V，不(bu)但解決了(le)(le)現(xian)場試(shi)(shi)驗(yan)(yan)所需電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)，同時還可作為(wei)其他野外作業(ye)的(de)備(bei)用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)。

1、高性(xing)能、帶載(zai)能力強：本電(dian)源采用(yong)美(mei)國最(zui)先(xian)進逆變技術，供(gong)電(dian)質量高，適應各(ge)種負載(zai)，比如馬達(da)、空(kong)調、電(dian)鉆、日光燈、氣(qi)體燈等家電(dian)設備(bei)，通信設備(bei)，工業設備(bei)。

2、高可(ke)靠(kao)：采用先進技術和冗(rong)余(yu)設(she)計，并配置工頻變壓(ya)器,由CPU控制(zhi)，選(xuan)用優(you)質元器件精(jing)心制(zhi)造，性能穩定，可(ke)靠(kao)性高。

3、保護(hu)完善(shan)：具有輸入過(guo)欠壓(ya)保護(hu)；輸出過(guo)載(zai)、過(guo)流、短路保護(hu)；整機過(guo)溫保護(hu)等(deng)，可以抗拒大電流啟動負(fu)載(zai)沖擊。

4、界面(mian)友好：LCD/LED顯示(shi):工作狀態、輸出電壓，電池電壓、頻率、負載率、故障等信息(xi)清晰(xi)明了；并(bing)且有聲光(guang)故障報警(jing)、指示(shi)故障等功能。

5、 操作(zuo)簡單：智能(neng)開關機，自動化程(cheng)度高，操作(zuo)方(fang)便。

6、 結(jie)構(gou)(gou)簡潔(jie)(jie)：機內功(gong)能部件采用(yong)模塊化設計，結(jie)構(gou)(gou)簡潔(jie)(jie)，維護方便。

7、 攜帶方便(bian)：拉桿箱設計(ji)，便(bian)于(yu)現場使(shi)用。

8、 效(xiao)率高,節能(neng)：空載電流小,在沒(mei)有負載情況下節約能(neng)源。

9、智(zhi)能電(dian)(dian)池(chi)(chi)管理：智(zhi)能電(dian)(dian)池(chi)(chi)監(jian)測管理系(xi)統，加(jia)強電(dian)(dian)池(chi)(chi)監(jian)測，延長電(dian)(dian)池(chi)(chi)壽命(ming)和利用率。直(zhi)流供電(dian)(dian)電(dian)(dian)路下限保護設計(ji)，當(dang)直(zhi)流電(dian)(dian)源低于保護電(dian)(dian)壓，逆變器將自動關閉。
