Kunezinyathelo ezimbalwa ekuhlolweni kokusebenza komhloli wokumelana nokufakwa kwe-insulation

Umhloli wokumelana nokufakwa kwe-insulation usetshenziswa ikakhulukazi ukukala ukumelana nokufakwa kwama-transformer amakhulu, ama-transformer, ama-generator, ama-motor-voltage aphezulu, ama-capacitor amandla, izintambo zikagesi, izibambisi nezinye izinto zokusebenza.

I-GD3127/3128 Insulation Resistance Tester

Ukusebenza kanye nezinyathelo zokuhlola zomhloli wokumelana nokufakwa kwe-insulation:

(1) I-shaker kufanele ikhethwe ngokwezinga lamandla kagesi wempahla.Kuma-transformer angu-10KV-35KV, kufanele kusetshenziswe i-2500 volt shaker.

(2) Ngaphambi kokulinganisa ukumelana nokufakwa kwe-insulation, ukunikezwa kwamandla kwempahla evivinywayo kufanele kunqanyulwe, kanye nokukhishwa kwe-short-circuit discharge, inhloso yokukhipha ukuvikela ukuphepha kwabantu nezinto zokusebenza, kanye nokwenza isilinganiso. imiphumela inembe;

(3) Ukuxhuma kwe-shaker kufanele kube izintambo ezimbili ezihlukene ezihlukene (imibala emibili) ene-insulation enhle, emibili Ungasonti izintambo ezixhuma ndawonye, ​​futhi ungenzi izintambo ezixhumanisayo zixhumane nomhlabathi, ukuze ugweme amaphutha abangelwa ubuthakathaka. i-insulation yezintambo zokuxhuma;

(4) Ngaphambi kokulinganisa, yenza ukuhlola kwesekhethi evulekile kanye nesekethe emfishane ku-shaker ukuze uhlole ukuthi i-shaker isesimweni esihle yini nokuthi i-transformer ivalekile.Uma umhloli wokumelana evula imigqa emibili exhumayo bese enyakazisa isibambo, i-pointer kufanele ikhombe ku-∞ (infinity).Ngalesi sikhathi, uma imigqa emibili yokuxhuma ifinyezwa okwesikhashana, i-pointer kufanele ikhombe ku-0, okusho ukuthi i-shaker isesimweni esihle., ngaphandle kwalokho kunephutha etafuleni elinyakazayo;

(5) Indlela yezintambo zokunyakazisa ukumelana nokufakwa kwe-insulation of the primary winding of the primary winding and the ground (igobolondo): Isekhethi emfishane amatheminali ezigaba ezintathu i-lU, lV kanye no-1W yokujikajika okuyinhloko enezintambo zethusi ezingenalutho, ukuze ukuxhuma ekugcineni kwe-"L" ye-megohmmeter;i-short-circuit amatheminali N, 2U, 2V, 2W kanye nomhlabathi (uqweqwe lomhlaba) we-secondary winding enezintambo zethusi ezingenalutho, bese uzixhuma ekupheleni kwe-"E" ye-megohmmeter;uma kunesidingo, ukuze kuncishiswe ithonya lokuvuza kwendawo enanini elilinganisiwe, ucingo lwethusi olungenalutho lungalinyazwa esiketini se-porcelain somkhono we-porcelain oseceleni okuyisisekelo ukuphenduka okumbalwa, bese sixhunywa ekugcineni kwe-“G” i-megohmmeter ene-insulated wire;

(6) Nyakazisa isilinganiso sepheya yesibili yokujikajika Indlela yokufaka izintambo yokumelana nokufakwa kwamajika okujika okuyinhloko kanye nomhlabathi (igobolondo): i-short-circuit amatheminali angu-2U, 2V, 2W, kanye no-N wamawindi esibili anezintambo zethusi ezingenalutho. .Ukuze uxhumeke "L" ekupheleni megohmmeter;ngemva kokujikeleza isikhashana isigaba sesithathu sihola i-1U, 1V, 1W kanye nomhlabathi (igobolondo) ye-winging eyinhloko enezintambo zethusi ezingenalutho, zixhume ekugcineni "E" ye-megger;Ukuze kuncishiswe ithonya lokuvuza kwendawo enanini elilinganisiwe, ucingo lwethusi olungenalutho lungaboshwa eduze kwesiketi se-porcelain somkhono we-porcelain oseceleni kwesibili amajika ambalwa, bese luxhunywa ekugcineni kuka-“G” kwe-megohmmeter ngocingo oluvalekile. .

(7) Lapho ukala, cindezela igobolondo le-shaker ngesandla esisodwa (ukuvimbela isithukuthezi ukuthi singadlidlizi).Lapho i-pointer ibonisa u-0, yeka ukuthuthumela ngokushesha ukuze ugweme ukushisa iwashi;

(8) Lapho ukala, beka itafula elinyakazayo endaweni evundlile, phendula isibambo esinyakazayo sejeneretha ngesivinini esingaba ama-revolution ayi-120 ngomzuzu, futhi ufunde ngo-15s Thatha inombolo (R15), ufunde enye inombolo (R60) 60s, futhi urekhode idatha enyakazayo.
