Yuav Ua Li Cas Ntsuas Kev Ua Haujlwm ntawm Fais Fab Transformers

Fais fab transformersyog cov khoom tseem ceeb hauv daim phiaj hluav taws xob, lub luag haujlwm rau kev hloov pauv hluav taws xob thiab kev xa hluav taws xob ruaj khov. Txhawm rau kom ntseeg tau tias lawv txoj haujlwm txhim khu kev qha thiab lub neej ua haujlwm ntev, kev ntsuas kev ua haujlwm tsis tu ncua yog qhov tseem ceeb. Cov kev ntsuam xyuas no pab txheeb xyuas qhov tsis xws luag, txheeb xyuas kev ua raws li cov qauv, thiab tiv thaiv qhov ua tsis tau tiav. Hauv qab no yog cov kev ntsuam xyuas tseem ceeb rau lub zog transformers thiab lawv lub hom phiaj.

Ua ntej, lem ratio test yog ib qho tseem ceeb xyuas kom paub meej tias qhov piv ntawm cov thawj mus rau theem nrab windings. Siv lub ntsuas ntsuas ntsuas ntsuas, cov kws tshaj lij siv qhov hluav taws xob qis rau ib qho cua thiab ntsuas qhov induced voltage ntawm lwm qhov. Qhov tshwm sim yuav tsum sib phim lub transformer tus nqi piv nyob rau hauv ib tug me me kam rau ua (feem ntau ± 0.5%). Deviations yuav qhia tau tias winding puas, luv Circuit Court, los yog tsis raug kais chaw, uas yuav cuam tshuam rau voltage tswj.

Qhov thib ob, kev ntsuas hluav taws xob tiv thaiv ntsuas ntsuas kev ncaj ncees ntawm lub tshuab hluav taws xob lub rwb thaiv tsev. Lub megohmmeter siv lub siab DC voltage ntawm windings thiab transformer tank, ntsuas qhov tsis kam. Cov txiaj ntsig tsis tshua muaj siab qhia txog kev nqus dej noo, kev sib kis, lossis kev puas tsuaj ntawm rwb thaiv tsev, uas ua rau muaj kev pheej hmoo ntawm hluav taws xob tawg. Qhov kev sim no tseem ceeb tshwj xeeb tshaj yog tom qab lub sijhawm ntev cia lossis raug rau qhov chaw ntub dej.

Thib peb, tsis muaj -load poob thiab kev ntsuas tam sim no ntsuas lub zog siv los ntawm lub tshuab hluav taws xob thaum tsuas yog thawj lub tshuab winding yog energized. High tsis muaj- load poob yuav qhia tau hais tias cov teeb meem tseem ceeb, xws li luv luv laminations los yog cov tub ntxhais sib dhos tsis zoo. Ntau dhau tsis muaj- thauj khoom tam sim no, lub sijhawm no, tuaj yeem teeb liab winding faults lossis teeb meem sib nqus Circuit Court. Cov kev ntsuam xyuas no yog ua los ntawm qhov ntsuas voltage thiab zaus kom simulate cov kev ua haujlwm tiag tiag.

Plaub, load poob thiab impedance kuaj ntsuas lub transformer efficiency nyob rau hauv load. Los ntawm luv luv -circuiting qhov thib ob winding thiab siv qhov hluav taws xob qis rau thawj, cov kws tshaj lij ntsuas lub zog poob (tooj liab poob) thiab impedance. Kev poob siab siab tuaj yeem taw qhia txog cov teeb meem tsis sib haum xeeb lossis kev sib txuas tsis zoo ntawm tus neeg xyuas pib, thaum lub impedance txawv txav tuaj yeem cuam tshuam rau lub tshuab hluav taws xob tsis raug cai thiab kev tswj hluav taws xob.

Thaum kawg, ib feem ntawm qhov kev ntsuam xyuas pom pom cov hluav taws xob sab hauv uas tuaj yeem cuam tshuam cov rwb thaiv tsev nyob rau lub sijhawm. Siv cov cuab yeej tshwj xeeb, cov kws tshaj lij ntsuas kev ua haujlwm tawm hauv qhov hluav taws xob siab. Txawm tias me me ib nrab tso tawm tuaj yeem nce mus rau qhov ua txhaum loj yog tias tsis muaj kev kho, ua qhov kev sim no tseem ceeb rau nruab nrab thiab siab -voltage transformers.

Hauv kev xaus, kev ntsuas kev ua tau zoo yog qhov tseem ceeb rau kev tswj xyuas kev noj qab haus huv ntawm lub zog hloov hluav taws xob. Los ntawm kev ua cov kev ntsuam xyuas no tsis tu ncua, cov neeg ua haujlwm tuaj yeem ua kom cov tshuab hloov pauv ua haujlwm tau zoo, nyab xeeb, thiab ntseeg tau, txo qis qis qis thiab txuas ntxiv lawv lub neej kev pabcuam.
