Pali masitepe angapo pakuyesa kwa opareshoni ya tester insulation resistance

The Insulation resistance tester imagwiritsidwa ntchito kwambiri kuyeza kukana kwazitsulo zosinthira zazikulu, zosinthira, ma jenereta, ma mota okwera kwambiri, ma capacitor amagetsi, zingwe zamagetsi, zomangira ndi zida zina.

GD3127/3128 Insulation Resistance Tester

Kugwiritsa ntchito ndi kuyesa masitepe a tester insulation resistance:

(1) Wogwedeza ayenera kusankhidwa molingana ndi mphamvu yamagetsi ya zida.Kwa ma thiransifoma a 10KV-35KV, shaker ya 2500 volt iyenera kugwiritsidwa ntchito.

(2) Musanayambe kuyeza kukana kutchinjiriza, mphamvu yamagetsi ya zida zomwe zikuyesedwa ziyenera kudulidwa, ndi Kutulutsa kutulutsa kwafupipafupi, cholinga cha kutulutsa ndikuteteza chitetezo cha anthu ndi zida, ndikupanga miyeso. zotsatira zolondola;

(3) Kulumikizana kwa shaker kuyenera kukhala mawaya awiri osiyana (mitundu iwiri) yokhala ndi kutchinjiriza bwino, awiri Osapotoza mawaya olumikizira palimodzi, ndipo musapangitse mawaya olumikizirana pansi, kuti mupewe zolakwika zomwe zimachitika chifukwa chakusauka. kusungunula kwa mawaya olumikizira;

(4) Musanayambe kuyeza, yesetsani kuzungulira ndi kuyesa kwafupipafupi pa shaker kuti muwone ngati shaker ili bwino ndipo thiransifoma imatsekedwa.Ngati woyesa kukana atsegula mizere iwiri yolumikizira ndikugwedeza chogwirira, cholozeracho chiyenera kuloza pa ∞ (infinity).Panthawiyi, ngati mizere iwiri yolumikizira ili yofupika kwakanthawi, cholozeracho chiyenera kuloza 0, zomwe zikutanthauza kuti chogwedezacho chili bwino., mwinamwake pali cholakwika mu tebulo logwedezeka;

(5) The mawaya njira kugwedeza kutchinjiriza kukana wa mapiringidzo pulayimale kuti mapiringidzo yachiwiri ndi pansi (chipolopolo): Short-wozungulira magawo atatu ma terminals lU, lV ndi 1W wa mapiringidzo pulayimale ndi opanda mkuwa mawaya , kuti kulumikiza ku "L" kumapeto kwa megohmmeter;kufupikitsa ma terminals N, 2U, 2V, 2W ndi nthaka (kutsika kwapansi) kwa mafunde achiwiri okhala ndi mawaya amkuwa opanda kanthu, kenako ndikulumikiza ku "E" kumapeto kwa megohmmeter;ngati kuli kofunikira, kuti muchepetse mphamvu ya kutayikira pamtunda pamtengo woyezedwa, waya wopanda mkuwa ukhoza kuvulala pa siketi ya porcelain ya manja a porcelain ozungulira pang'ono, kenako ndikulumikizidwa ndi "G" kumapeto kwa megohmmeter ndi waya wotsekedwa;

(6) Gwirani muyeso wa awiri opiringizika achiwiri Njira yamawaya a kukana kwa kutchinjiriza kwa mapindikidwe oyambira ndi pansi (chipolopolo): mtunda waufupi wa 2U, 2V, 2W, ndi N ma terminals achiwiri okhala ndi mawaya amkuwa opanda kanthu. .Kuti mugwirizane ndi "L" kumapeto kwa megohmmeter;pambuyo yochepa-circuiting atatu gawo amatsogolera 1U, 1V, 1W ndi nthaka (chipolopolo) cha mapiringidzo pulayimale ndi opanda mkuwa mawaya, kulumikiza iwo "E" mapeto a megger;Kuchepetsa mphamvu ya kutayikira kwamadzi pamtengo woyezedwa, waya wopanda mkuwa ukhoza kuzunguliridwa mozungulira siketi yadothi yam'mbali yam'mbali yam'mbali yaporcelain kamphindi kakang'ono, kenako ndikulumikizidwa ku "G" kumapeto kwa megohmmeter ndi waya wotsekeredwa. .

(7) Poyezera, kanikizani chigoba cha shaker ndi dzanja limodzi (kuteteza wogwedeza kuti asagwedezeke).Pamene cholozera chikuwonetsa 0, siyani kugwedeza nthawi yomweyo kuti musawotche wotchi;

(8) Poyesa, ikani tebulo logwedezeka pamalo opingasa, tembenuzani chogwirira chogwedeza cha jenereta pa liwiro la kuzungulira 120 pa mphindi imodzi, ndipo werengani pa 15s Tengani nambala (R15), werengani nambala ina (R60) pa. 60s, ndikulemba zomwe zikugwedeza.
