10kv變壓器是在同類產品YDJ(G)型高壓試驗變壓器的基礎上，按試驗變壓器標準要求，經改進后生產的一種新型產品，本系列產品具有體積小、重量輕、結構緊湊、功能齊全、使用方便等特點。

　　10kv變壓(ya)器鐵芯為單(dan)框(kuang)式(shi)。線(xian)圈采用(yong)同芯圓(yuan)筒多(duo)層塔(ta)式(shi)結構，初(chu)級低(di)壓(ya)繞(rao)組繞(rao)在(zai)鐵芯上，次級高(gao)壓(ya)繞(rao)組繞(rao)在(zai)低(di)壓(ya)繞(rao)組外(wai)側，這(zhe)種同軸布置(zhi)減少了繞(rao)組間的(de)藕合損耗。高(gao)壓(ya)硅堆用(yong)特殊工藝封裝在(zai)套管內，產品的(de)外(wai)殼制成(cheng)與器芯配合較佳的(de)八角形結構，整(zheng)體外(wai)型美觀大方。

　　工作原理

　　交直流(liu)兩用型高壓(ya)(ya)試驗變(bian)壓(ya)(ya)器工(gong)作原(yuan)理(li)所示：高壓(ya)(ya)套(tao)管內裝有(you)整流(liu)硅(gui)堆，串接在(zai)高壓(ya)(ya)回路(lu)中作高壓(ya)(ya)整流(liu)，以(yi)獲(huo)(huo)得(de)直流(liu)高電壓(ya)(ya)。當用一短路(lu)桿將(jiang)高壓(ya)(ya)硅(gui)堆短接時，可獲(huo)(huo)得(de)交流(liu)高電壓(ya)(ya)，其狀態(tai)為交流(liu)輸出;反(fan)之(zhi)在(zai)抽(chou)出短路(lu)桿時，其狀態(tai)為直流(liu)輸出。

　　使用方法及注(zhu)意事項

　　按照所進行的(de)(de)工頻(pin)耐壓試(shi)驗(yan)接(jie)(jie)好工作(zuo)線路(lu)，抽出短路(lu)桿,試(shi)驗(yan)變壓器(qi)的(de)(de)高(gao)壓繞阻(zu)的(de)(de)X端(duan)(高(gao)壓尾)、儀表(biao)測量繞組(zu)的(de)(de)F端(duan)、試(shi)驗(yan)變壓器(qi)的(de)(de)外殼以及電源控制箱(xiang)(臺)的(de)(de)外殼必須可靠接(jie)(jie)地(di)。

　　接電(dian)(dian)(dian)源前，電(dian)(dian)(dian)源控制箱(臺)的調壓(ya)器必(bi)須調到零(ling)位(wei)(wei)(零(ling)位(wei)(wei)指(zhi)示(shi)(shi)燈亮)。接通電(dian)(dian)(dian)源后紅色指(zhi)示(shi)(shi)燈亮，按一下啟動按鈕(niu)，綠色指(zhi)示(shi)(shi)燈亮，表示(shi)(shi)試(shi)驗變(bian)壓(ya)器已接通控制電(dian)(dian)(dian)源，開始升壓(ya)。

　　從零(ling)位開(kai)始(shi)(shi)按順時(shi)針方向勻(yun)速(su)(su)(su)旋轉調(diao)壓(ya)(ya)(ya)(ya)(ya)(ya)器手輪升(sheng)(sheng)壓(ya)(ya)(ya)(ya)(ya)(ya)。(升(sheng)(sheng)壓(ya)(ya)(ya)(ya)(ya)(ya)方式有：快速(su)(su)(su)升(sheng)(sheng)壓(ya)(ya)(ya)(ya)(ya)(ya)法(fa)，即20S逐級升(sheng)(sheng)壓(ya)(ya)(ya)(ya)(ya)(ya)法(fa)，慢速(su)(su)(su)升(sheng)(sheng)壓(ya)(ya)(ya)(ya)(ya)(ya)法(fa)，即60S逐級升(sheng)(sheng)壓(ya)(ya)(ya)(ya)(ya)(ya)法(fa)，極慢速(su)(su)(su)升(sheng)(sheng)壓(ya)(ya)(ya)(ya)(ya)(ya)法(fa)供(gong)選(xuan)(xuan)用)電(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)從零(ling)開(kai)始(shi)(shi)按選(xuan)(xuan)定的升(sheng)(sheng)壓(ya)(ya)(ya)(ya)(ya)(ya)速(su)(su)(su)度(du)升(sheng)(sheng)到您(nin)所需(xu)額(e)定試(shi)(shi)驗(yan)電(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)的75%后(hou)(hou)，再以每(mei)秒2%額(e)定試(shi)(shi)驗(yan)電(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)的速(su)(su)(su)度(du)升(sheng)(sheng)到您(nin)所需(xu)試(shi)(shi)驗(yan)電(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)，并密切注(zhu)意測量儀表的指(zhi)示以及(ji)被(bei)試(shi)(shi)品的情(qing)況，被(bei)試(shi)(shi)品施加電(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)的時(shi)間到后(hou)(hou)。應在數秒內勻(yun)速(su)(su)(su)將調(diao)壓(ya)(ya)(ya)(ya)(ya)(ya)器返回，高(gao)壓(ya)(ya)(ya)(ya)(ya)(ya)降(jiang)至1/3試(shi)(shi)驗(yan)電(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)以下，按一下停止按鈕，高(gao)壓(ya)(ya)(ya)(ya)(ya)(ya)、低壓(ya)(ya)(ya)(ya)(ya)(ya)輸出停止，然后(hou)(hou)切斷電(dian)(dian)源線，試(shi)(shi)驗(yan)完畢。

　　(1)試(shi)驗(yan)(yan)(yan)人員應做好責(ze)任(ren)分(fen)工(gong)，設定(ding)好試(shi)驗(yan)(yan)(yan)現場的安全距離，仔(zi)細檢(jian)查好被試(shi)品(pin)及試(shi)驗(yan)(yan)(yan)變壓器的接地情(qing)況，并設有專人監(jian)護安全及觀察(cha)被試(shi)品(pin)狀態工(gong)作。

　　(2)被試(shi)品做(zuo)試(shi)驗前，應拆(chai)除所有對外連(lian)線(xian)，并充分放電，主(zhu)要(yao)部位應清除干凈(jing)，保(bao)持干燥，以免損壞被試(shi)品及(ji)帶來試(shi)驗數值的誤(wu)差。

　　(3)對(dui)于大容量試(shi)品(電(dian)(dian)容器、超長電(dian)(dian)纜等)試(shi)驗時應緩(huan)慢升(sheng)壓(ya)，防止被試(shi)品的充(chong)電(dian)(dian)電(dian)(dian)流過大而燒(shao)壞微安(an)表，必(bi)要時應分級(ji)加壓(ya)分別讀取各電(dian)(dian)壓(ya)下微安(an)表的穩定(ding)讀數。

　　(4)試驗過程(cheng)中(zhong)，應(ying)嚴(yan)密監(jian)視(shi)被試品(pin)、微安表及(ji)試驗裝置等，一旦發生(sheng)閃爍、擊穿(chuan)等現(xian)象應(ying)立即降壓，切(qie)斷電源(yuan)，并查明(ming)原因。
