利用全自動變壓比測試儀判斷有載調容調壓開關

　　目前現場試驗中普遍應用的的全自動變壓比測試儀，也能夠反映有載調容調壓開關電路在切換過程中出現的開路故障。全自動變壓比測試儀在完成正確的試驗接線后，可以在有載分接開關進行(xing)(xing)(xing)分(fen)接(jie)(jie)變(bian)(bian)(bian)(bian)換(huan)(huan)(huan)時(shi)，進行(xing)(xing)(xing)繞組所(suo)(suo)有檔(dang)位(wei)的(de)變(bian)(bian)(bian)(bian)壓(ya)比測(ce)(ce)試(shi)(shi)，但測(ce)(ce)試(shi)(shi)前(qian)儀器需(xu)要(yao)對該(gai)變(bian)(bian)(bian)(bian)壓(ya)器的(de)聯(lian)結組別等參(can)數進行(xing)(xing)(xing)預(yu)先設置(zhi)。有載(zai)(zai)分(fen)接(jie)(jie)開(kai)關(guan)(guan)進行(xing)(xing)(xing)分(fen)接(jie)(jie)變(bian)(bian)(bian)(bian)換(huan)(huan)(huan)時(shi)，如(ru)果試(shi)(shi)驗(yan)接(jie)(jie)線(xian)(xian)正(zheng)確(que)(que)(que)(que)、參(can)數設置(zhi)正(zheng)確(que)(que)(que)(que)，變(bian)(bian)(bian)(bian)壓(ya)比測(ce)(ce)試(shi)(shi)能(neng)夠(gou)在(zai)所(suo)(suo)有檔(dang)位(wei)上(shang)正(zheng)確(que)(que)(que)(que)進行(xing)(xing)(xing)，則(ze)有載(zai)(zai)分(fen)接(jie)(jie)開(kai)關(guan)(guan)在(zai)切換(huan)(huan)(huan)過程(cheng)中(zhong)(zhong)應當不存在(zai)開(kai)路故障。如(ru)果變(bian)(bian)(bian)(bian)壓(ya)比測(ce)(ce)試(shi)(shi)儀在(zai)某兩個(ge)檔(dang)位(wei)的(de)切換(huan)(huan)(huan)過程(cheng)中(zhong)(zhong)自動終止測(ce)(ce)試(shi)(shi)工作(zuo)，并給出一些(xie)提示，比如(ru)“試(shi)(shi)驗(yan)接(jie)(jie)線(xian)(xian)錯誤(wu)"或“聯(lian)結組別設置(zhi)錯誤(wu)"等信息，則(ze)很有可能(neng)表明有載(zai)(zai)分(fen)接(jie)(jie)開(kai)關(guan)(guan)在(zai)這(zhe)兩個(ge)檔(dang)位(wei)之(zhi)間的(de)切換(huan)(huan)(huan)過程(cheng)中(zhong)(zhong)出現(xian)了開(kai)路故障。因為我們已經能(neng)夠(gou)確(que)(que)(que)(que)定試(shi)(shi)驗(yan)接(jie)(jie)線(xian)(xian)正(zheng)確(que)(que)(que)(que)、參(can)數設置(zhi)正(zheng)確(que)(que)(que)(que)，那(nei)么只有在(zai)切換(huan)(huan)(huan)過程(cheng)中(zhong)(zhong)發(fa)生(sheng)開(kai)路故障，強行(xing)(xing)(xing)終止了儀器測(ce)(ce)試(shi)(shi)過程(cheng)中(zhong)(zhong)采樣信號的(de)連續傳(chuan)送，才能(neng)導(dao)致儀器發(fa)出“試(shi)(shi)驗(yan)接(jie)(jie)線(xian)(xian)錯誤(wu)"或“聯(lian)結組別設置(zhi)錯誤(wu)"等錯誤(wu)信息。
