為了(le)試(shi)(shi)驗臺的(de)安全運行和準確的(de)測量(liang)﹑高(gao)效(xiao)的(de)工作敬請(qing)廣大操作人(ren)員熟(shu)練掌(zhang)握(wo)，對(dui)試(shi)(shi)驗臺設計(ji)合理性以(yi)及性能上望請(qing)有(you)關工程技術人(ren)員提出寶貴意見，讓我們的(de)工作更加(jia)完善。

五﹑注意事項：

1.當試品(pin)回路電(dian)阻過大(da)時(shi)，不能輸(shu)出(chu)所設定的(de)電(dian)流值時(shi)，觸摸屏顯(xian)示的(de)是zui大(da)輸(shu)出(chu)電(dian)流值。這(zhe)時(shi)可(ke)以通過調整(zheng)(zheng)保護器(qi)的(de)整(zheng)(zheng)定值來進(jin)行試驗。

2.綜保短(duan)路保護(hu)動作時(shi)間(jian)測試(shi)時(shi)，應先(xian)試(shi)驗一下試(shi)品的短(duan)路保護(hu)是否正常，正常后在接入測試(shi)回路，進行保護(hu)時(shi)間(jian)測試(shi)。

3.測試無補償和有補償下的漏(lou)電(dian)電(dian)流時，應盡量縮(suo)短測試時間，以避免燒壞內(nei)置的1k歐姆(mu)電(dian)阻(zu)。無補償的電(dian)流測試一次后(hou)，這組數據可作為以后(hou)的參考值。

六﹑日常維護與常見故障排除

1． 定期保持試(shi)(shi)驗(yan)臺位的整潔，每(mei)次試(shi)(shi)驗(yan)時都應該按(an)照操作規(gui)程(cheng)進行(xing)，試(shi)(shi)驗(yan)前仔細檢查試(shi)(shi)驗(yan)回路正確后方可進行(xing)試(shi)(shi)驗(yan)。

2． 當開關內阻較大時，會影響電流的正常(chang)輸出，zui后只(zhi)能顯(xian)示出不足的電流值，此現象為正常(chang)。

3． 常(chang)見(jian)故障及排除方法：

三．1kΩ電阻動作試驗

步驟1. 將(jiang)饋(kui)電開關的(de)(de)(de)主回(hui)路(lu)和(he)控制回(hui)路(lu)分開，引出主變壓器輸入端的(de)(de)(de)兩(liang)根導(dao)線(xian)接至試(shi)驗臺端子板(ban)的(de)(de)(de)φ1﹑φ2﹑φ3任意(yi)兩(liang)相(xiang)。根據試(shi)品的(de)(de)(de)主回(hui)路(lu)電壓等級要求選擇(ze)相(xiang)應的(de)(de)(de)電壓輸出，保證試(shi)品的(de)(de)(de)正常(chang)吸合。

試驗接線圖如(ru)圖（3）示：

以(yi)上(shang)是對于(yu)(yu)饋(kui)電開關的(de)1K電阻漏(lou)電動作試(shi)驗，而對于(yu)(yu)照明綜保，煤電鉆綜保的(de)漏(lou)電試(shi)驗略有不同。

四．照明、煤電鉆綜保的1K電阻漏電動作、短路動作時間測試試驗

步驟1. 將(jiang)綜(zong)保(bao)(bao)開關的(de)(de)(de)主(zhu)回路與(yu)試(shi)驗(yan)臺(tai)端(duan)子板的(de)(de)(de)φ1﹑φ2﹑φ3三(san)相相連。綜(zong)保(bao)(bao)的(de)(de)(de)負荷端(duan)與(yu)試(shi)驗(yan)臺(tai)的(de)(de)(de)φ14﹑φ15﹑φ16相連。根據試(shi)品的(de)(de)(de)主(zhu)回路電壓(ya)等(deng)級要求選擇相應的(de)(de)(de)電壓(ya)輸出，保(bao)(bao)證試(shi)品的(de)(de)(de)正常吸合。

步驟2.將接線端(duan)子的φ9、φ10用測試線接至試品的輔助常(chang)開節點上(shang)。

步驟3.將“1K電阻動作(zuo)相位選擇”用測試(shi)(shi)(shi)線φ11接至試(shi)(shi)(shi)品(pin)的三相中需測試(shi)(shi)(shi)的一端(duan)上，試(shi)(shi)(shi)品(pin)外殼(ke)用測試(shi)(shi)(shi)線于臺(tai)位的“G至試(shi)(shi)(shi)品(pin)外殼(ke)”端(duan)子相連。

步驟4.閉合(he)綜(zong)保(bao)隔離開(kai)關(guan)，啟動(dong)相應的(de)電壓輸出，啟動(dong)“電鉆”按鈕，電鉆開(kai)始運行。

步驟5.按下“1K電(dian)阻動作(zuo)”按鈕，計時開(kai)始，當綜(zong)保開(kai)關(guan)動作(zuo)時，計時器停止計時。記錄“電(dian)阻/時間(jian)”儀(yi)表上的(de)時間(jian)（XXXX毫秒(miao)），此時間(jian)即為(wei)綜(zong)保1k歐(ou)漏(lou)電(dian)電(dian)阻的(de)動作(zuo)時間(jian)。

漏電試驗完成后，將綜保開關復位（斷電復位），接著可以進行短路保護動作時間測試。（注：短路保護試驗前，按下試品綜保開關的短路試驗按鈕，看看試品保護時候正常，正常后在進行短路保護時間測試）

試(shi)驗步驟同上試(shi)驗的前五(wu)步。

步(bu)驟6. 對于煤電鉆(zhan)綜保(bao)(bao)按(an)下(xia)“電鉆(zhan)短路(lu)”按(an)鈕（照明(ming)綜保(bao)(bao)按(an)下(xia)“照明(ming)短路(lu)”按(an)鈕），計時(shi)(shi)開(kai)始，當綜保(bao)(bao)開(kai)關動作時(shi)(shi)，計時(shi)(shi)器停止計時(shi)(shi)。記錄“電阻/時(shi)(shi)間”儀表上的時(shi)(shi)間（XXXX毫(hao)秒），此時(shi)(shi)間即(ji)為綜保(bao)(bao)短路(lu)保(bao)(bao)護的保(bao)(bao)護時(shi)(shi)間。

試驗接線(xian)圖如圖（4）示：

在(zai)以上兩試驗中，我們同時可以觀(guan)察綜保(bao)(bao)變壓器的原邊三相電(dian)流，副(fu)邊三相電(dian)壓，通過三相電(dian)流、電(dian)壓的不平度來判斷綜保(bao)(bao)的變壓器性能是否滿足使用(yong)要求。

五．電容補償試驗

步驟(zou)1.用測試線將“電容(rong)補(bu)償相位選擇”和三相電壓(ya)輸(shu)出端(duan)中(zhong)的一端(duan)相連。

步驟2.根據試(shi)品開(kai)關(guan)的(de)電(dian)壓等(deng)級調整輸出電(dian)壓（方(fang)法同(tong)上(shang)），按下“660/1140”按鈕，電(dian)壓輸出。

步驟3.根據試驗所需的補償電容大小，相應按下“0.22uf”，“0.47uf”，“1.0uf”，先斷開試品補償電路，使網路在無補償(chang)下，電(dian)容補償(chang)儀(yi)表中顯示值為無補償(chang)狀(zhuang)態下的漏電(dian)電(dian)流I1。

步驟4.開啟試品開關的補償電路，重復步驟3的操作，此時在(zai)“電容(rong)補(bu)償(chang)”儀(yi)表中顯示(shi)值為有補(bu)償(chang)狀態下的漏電電流(liu)I2。

步驟5.根(gen)據公式：補償(chang)率＝（I1-I2）/I1*100% 計(ji)算補償(chang)率>60％可判斷(duan)試品合格。
