MD-2001便(bian)攜(xie)式工頻試驗電(dian)源
電(dian)(dian)(dian)(dian)(dian)(dian)力系統中的(de)(de)(de)試(shi)(shi)驗(yan)現場(chang)(chang)，由于停電(dian)(dian)(dian)(dian)(dian)(dian)檢修或者(zhe)新建變(bian)電(dian)(dian)(dian)(dian)(dian)(dian)站未(wei)能投運(yun)，都會(hui)(hui)造成現場(chang)(chang)試(shi)(shi)驗(yan)缺(que)少試(shi)(shi)驗(yan)所用(yong)(yong)的(de)(de)(de)工頻(pin)(pin)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)，為(wei)滿足現場(chang)(chang)試(shi)(shi)驗(yan)的(de)(de)(de)需要，經(jing)常(chang)會(hui)(hui)使(shi)用(yong)(yong)發電(dian)(dian)(dian)(dian)(dian)(dian)機發電(dian)(dian)(dian)(dian)(dian)(dian)來(lai)供電(dian)(dian)(dian)(dian)(dian)(dian)，自帶(dai)發電(dian)(dian)(dian)(dian)(dian)(dian)機發電(dian)(dian)(dian)(dian)(dian)(dian)往往發出的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓不(bu)穩(wen)，頻(pin)(pin)率也不(bu)一定是純正(zheng)(zheng)50HZ正(zheng)(zheng)弦波(bo)，而許多試(shi)(shi)驗(yan)儀(yi)器對電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)壓穩(wen)定性及頻(pin)(pin)率要求較高。電(dian)(dian)(dian)(dian)(dian)(dian)壓不(bu)穩(wen)，頻(pin)(pin)率不(bu)是50HZ等都會(hui)(hui)造成試(shi)(shi)驗(yan)結果不(bu)準(zhun)確，甚至儀(yi)器因電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)不(bu)穩(wen)被(bei)損壞(huai)。即使(shi)在(zai)變(bian)電(dian)(dian)(dian)(dian)(dian)(dian)站有電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)情況下，有時(shi)現場(chang)(chang)取電(dian)(dian)(dian)(dian)(dian)(dian)也比較麻煩，要布較長電(dian)(dian)(dian)(dian)(dian)(dian)纜、需要接(jie)線(xian)、測試(shi)(shi)點離取電(dian)(dian)(dian)(dian)(dian)(dian)點距離較遠、電(dian)(dian)(dian)(dian)(dian)(dian)纜不(bu)夠長以及現場(chang)(chang)工作電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)受各種因素干擾造成嚴重的(de)(de)(de)諧(xie)波(bo)等原因，同樣會(hui)(hui)影響工作效率及試(shi)(shi)驗(yan)的(de)(de)(de)準(zhun)確性。為(wei)此，我(wo)們為(wei)了適應電(dian)(dian)(dian)(dian)(dian)(dian)力系統現場(chang)(chang)實際工作的(de)(de)(de)需要，研制(zhi)了一款(kuan)大容(rong)(rong)量便攜式工頻(pin)(pin)試(shi)(shi)驗(yan)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)，本(ben)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)采用(yong)(yong)大容(rong)(rong)量鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)池組為(wei)供電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)，經(jing)逆變(bian)器轉換輸(shu)出純50HZ正(zheng)(zheng)弦波(bo)，電(dian)(dian)(dian)(dian)(dian)(dian)壓為(wei)穩(wen)定的(de)(de)(de)交流220V，不(bu)但(dan)解(jie)決(jue)了現場(chang)(chang)試(shi)(shi)驗(yan)所需電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)，同時(shi)還(huan)可作為(wei)其他野外作業(ye)的(de)(de)(de)備用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)。

6、充(chong)(chong)電(dian)(dian)(dian)能力(li)強 :機(ji)內(nei)裝有自控(kong)充(chong)(chong)電(dian)(dian)(dian)技術的(de)(de)大(da)電(dian)(dian)(dian)流(liu)充(chong)(chong)電(dian)(dian)(dian)器，充(chong)(chong)電(dian)(dian)(dian)速度快，浮(fu)充(chong)(chong)電(dian)(dian)(dian)壓(ya)穩(wen)定,當采(cai)用外置蓄(xu)電(dian)(dian)(dian)池時，可以(yi)用本電(dian)(dian)(dian)源(yuan)為其充(chong)(chong)電(dian)(dian)(dian)，充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)可以(yi)0-70A可調節,三階段充(chong)(chong)電(dian)(dian)(dian)（恒(heng)流(liu)充(chong)(chong)電(dian)(dian)(dian) (恒(heng)流(liu)階段) → 恒(heng)壓(ya)充(chong)(chong)電(dian)(dian)(dian) (恒(heng)壓(ya)階段) → 浮(fu)充(chong)(chong) (恒(heng)壓(ya)階段) ） ，從而有效保護蓄(xu)電(dian)(dian)(dian)池，所以(yi)本電(dian)(dian)(dian)源(yuan)同時又是一臺高可靠的(de)(de)蓄(xu)電(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian)機(ji)。
7、結構(gou)簡(jian)潔 : 機(ji)內功能部(bu)件采用模(mo)塊(kuai)化(hua)設(she)計，結構(gou)簡(jian)潔，維護(hu)方便。
