工頻耐壓(ya)試驗(yan)操作過程注意事項

1、試(shi)驗人員應(ying)做好責任(ren)分工,設(she)定好試(shi)驗現場的(de)安(an)全(quan)距(ju)離(li),仔(zi)細檢查好被試(shi)品(pin)及試(shi)驗變(bian)壓器的(de)接地(di)情況,并設(she)有專人監護(hu)安(an)全(quan)及觀察被試(shi)品(pin)狀態工作(zuo)。

2、被(bei)試(shi)品(pin)主要(yao)部(bu)位應清(qing)理干(gan)凈，保(bao)持優良干(gan)燥，以免損壞被(bei)試(shi)品(pin)和帶來試(shi)驗數(shu)值(zhi)的誤(wu)差。

3、對大型設(she)備的試(shi)(shi)驗，一般都應先(xian)進行(xing)試(shi)(shi)驗變壓器的空升試(shi)(shi)驗，即不接(jie)試(shi)(shi)品時升壓至試(shi)(shi)驗電壓，以便(bian)校對好(hao)儀表的指示精度，調整好(hao)放電球隙的球間(jian)距。

4、做耐壓試(shi)驗時升壓速度(du)不(bu)(bu)能(neng)(neng)過快，并防止突然加壓，例如調壓器不(bu)(bu)在零(ling)位(wei)的突然合閘(zha)，也不(bu)(bu)能(neng)(neng)突然斷電，一般應(ying)在調壓器降至零(ling)位(wei)時分閘(zha)。

5、在升壓(ya)或耐(nai)壓(ya)試(shi)驗過程中，如(ru)發現(xian)下(xia)列不正常情(qing)況，1 電(dian)壓(ya)、電(dian)流表指針(zhen)擺動很大，2 被(bei)試(shi)品(pin)發出不正常響聲(sheng)，3 發現(xian)絕緣有燒焦或冒(mao)煙現(xian)象，應立(li)即(ji)降壓(ya)，切斷電(dian)源，停止試(shi)驗并查明原因。

6、使用(yong)本產品做高壓試驗時，除熟悉本說明書(shu)外，還(huan)必須嚴格執行國家有關標準(zhun)和(he)操作規(gui)程(cheng)。

直流泄(xie)漏(lou)試驗操作過程注意事項

（1）試驗人員應做好責任分工，設定好試驗現場的安全距離，仔細檢查好被試品及試驗變壓器的接地情況，并設有專人監護安全及觀察被試品狀態工作。
（2）被試品做試驗前，應拆除所有對外連線，并充分放電，主要部位應清理干凈，保持優良干燥，以免損壞被試品及帶來試驗數值的誤差。
（3）對于大容量試品（電容器、超長電纜等）試驗時應緩慢升壓，防止被試品的充電電流過大而燒壞微安表，必要時應分級加壓分別讀取各電壓下微安表的穩定讀數。
（4）試驗(yan)過程中，應(ying)嚴密監視被(bei)試品、微安(an)表及試驗(yan)裝置等，一旦發生閃爍、擊穿等現象應(ying)立即降壓，切斷(duan)電源，并查明原(yuan)因。

六、主要試驗設備的選擇

1、試驗變壓器
其高壓(ya)側(ce)額定(ding)電壓(ya)應(ying)不小于被(bei)試(shi)(shi)品的*高試(shi)(shi)驗電壓(ya)，額定(ding)電流(liu)(liu)不小于被(bei)試(shi)(shi)品的*大電容電流(liu)(liu)。被(bei)試(shi)(shi)品的電容電流(liu)(liu)和試(shi)(shi)驗變壓(ya)器所(suo)需容量(liang)計算式為：

被(bei)試品電容(rong)(rong)量(liang)Cx可由交流電橋測(ce)出(chu)。常用的被(bei)試品電容(rong)(rong)量(liang)按表1選取(qu)。

幾種常用被試品(pin)的電(dian)容量（pF） 表1

2、調壓設備

（1）自藕(ou)調(diao)壓(ya)器(qi)。其調(diao)壓(ya)范(fan)圍廣、功(gong)率(lv)損(sun)耗小、波(bo)形(xing)畸變(bian)小、選擇這(zhe)種(zhong)調(diao)壓(ya)方式為*好。自藕(ou)調(diao)壓(ya)器(qi)的(de)容量(liang)按0.75 ~ 1倍的(de)試(shi)驗變(bian)壓(ya)器(qi)的(de)容量(liang)選擇，適用于容量(liang)為100KVA以下的(de)試(shi)驗變(bian)壓(ya)器(qi)的(de)調(diao)壓(ya)。

（2）感應調壓(ya)器。其(qi)調壓(ya)范圍大，波形畸形小、但結構(gou)復雜、價格(ge)較貴，當(dang)試(shi)驗變壓(ya)器的(de)容(rong)量較大時（如100KVA以(yi)上）使(shi)用。

3、限流電阻

限流電阻的作用是，當被試品擊穿時，限制斷路電流，從而保護試驗變壓器，防止故障的擴大。其數值以*高試驗電壓為準，按0.5 ~ 1 Ω / V（有效值）選擇，限流電阻可用水電阻。注意水不能充滿玻璃管，應留有余地，以防爆裂。
4、放電球隙

放電(dian)球隙的(de)(de)布(bu)置方(fang)式有垂(chui)直和水平兩種，球隙間距S和球的(de)(de)直徑D的(de)(de)關系應(ying)保(bao)護(hu)(hu)在(zai)0.05D ≤S ≤0.5D范(fan)圍(wei)內，球隙上的(de)(de)水電(dian)阻阻值一般按(an)0.1 ~ 1Ω/V選取,設置放電(dian)球隙的(de)(de)目的(de)(de)是(shi)為了對重要的(de)(de)被試品起(qi)保(bao)護(hu)(hu)作(zuo)用,可以(yi)將由(you)于誤操作(zuo)或(huo)被試品擊穿引起(qi)的(de)(de)過電(dian)壓(ya)限制在(zai)允許(xu)的(de)(de)范(fan)圍(wei)內。
