Kukho amanyathelo amaninzi kuvavanyo lokusebenza komvavanyi wokumelana nokufakwa kwe-insulation

I-insulation resistant tester isetyenziselwa ukulinganisa ukuxhathisa ukugquma kwee-transformers ezinkulu, ii-transformers, iijeneretha, ii-motor high-voltage, ii-capacitors zamandla, iintambo zombane, ukubamba kunye nezinye izixhobo.

I-GD3127/3128 i-Insulation Resistance Tester

Ukusebenza kunye namanyathelo ovavanyo lwe-insulation resistance tester:

(1) Ishaker kufuneka ikhethwe ngokwenqanaba lombane lesixhobo.Kwi-transformers ye-10KV-35KV, i-2500 volt shaker kufuneka isetyenziswe.

(2) Phambi kokulinganisa ukuxhathisa ukugquma, unikezelo lombane lwesixhobo esiphantsi kovavanyo kufuneka lunqunyulwe, kwaye Ukuqhuba ukukhutshwa kwexesha elifutshane, injongo yokukhutshwa kukukhusela ukhuseleko lwabantu kunye nezixhobo, kunye nokwenza umlinganiselo. iziphumo zichanekile;

3 ukugquma kweengcingo zokudibanisa;

(4) Ngaphambi kokulinganisa, yenza isiphaluka esivulekileyo kunye novavanyo olufutshane lwesekethe kwi-shaker ukujonga ukuba i-shaker ikwimeko efanelekileyo kwaye i-transformer ifakwe i-insulated.Ukuba umvavanyi wokuchasa uvula imigca emibini yokudibanisa kwaye ugubungele isibambo, isalathisi kufuneka sibhekiselele ku-∞ (infinity).Ngeli xesha, ukuba imigca emibini yokudibanisa i-short short-circuited, isalathisi kufuneka ibhekisele ku-0, oku kuthetha ukuba i-shaker ikwimeko efanelekileyo., kungenjalo kukho impazamo kwitafile eshukumayo;

5 ukuqhagamshela kwi "L" ekupheleni megohmmeter;i-short-circuit i-terminals N, 2U, 2V, 2W kunye nomhlaba (i-crust earth) ye-second winding kunye neengcingo zobhedu ezingenanto, uze udibanise kwi-"E" ekupheleni kwe-megohmmeter;ukuba kuyimfuneko, ukuze kuncitshiswe impembelelo yokuvuza komphezulu kwixabiso elilinganisiweyo, ucingo olungenanto lobhedu lunokulimala kwi-skirt ye-porcelain yecala eliphambili lomkhono we-porcelain ngokujika okumbalwa, kwaye emva koko uqhagamshelwe kwi-"G" ekupheleni i-megohmmeter ene-insulated wire;

(6) Shukumisa umlinganiso wesibini sokujija isibini Indlela yocingo yokumelana nokugquma kweyona ndlela iphambili yokujikajika kunye nomhlaba (iqokobhe): i-short-circuit i-2U, 2V, 2W, kunye ne-N yeetheminali zojiko lwesibini oluneengcingo ezingenanto zobhedu. .Ukuze udibanise kwisiphelo "L" se-megohmmeter;emva kokujikeleza okufutshane kwinqanaba lesithathu likhokelela i-1U, 1V, 1W kunye nomhlaba (igobolondo) ye-primary winding kunye neengcingo zobhedu ezingenanto, zidibanise "E" ekupheleni kwe-megger;Ukunciphisa impembelelo yokuvuza komphezulu kwixabiso elilinganisiweyo, ucingo olungenanto lobhedu lunokuthi lufakwe kwi-skirt ye-porcelain yecala lesibini lomkhono we-porcelain ngokujika okumbalwa, kwaye emva koko uqhagamshelwe kwi-"G" ekupheleni kwe-megohmmeter ngocingo olugqunyiweyo. .

(7) Xa ulinganisa, cofa iqokobhe leshaker ngesandla esinye (ukuthintela isihlukuhli ukuba singangcangcazeli).Xa isalathisi sibonisa i-0, yeka ukugubha ngokukhawuleza ukuze ugweme ukutshisa iwashi;

(8) Xa ulinganisa, beka itafile eshukumayo kwindawo ethe tye, jika umqheba oshukumayo wejenereyitha ngesantya esimalunga ne-120 revolution ngomzuzu, uze ufunde ngo-15s Thatha inombolo (R15), ufunde enye inombolo (R60) 60s, kwaye urekhode idatha yokugubha.
