Muaj kev sib raug zoo polarity ntawm thawj sab thiab ob sab ntawm lub hwj chim transformer kauj. Yog hais tias muaj ob peb coils los yog ob peb lub hwj chim transformers ua ke, nws yog ib qho tsim nyog yuav tsum paub lawv cov polarity ua ntej lawv siv tau kom raug. Rau lub hwj chim transformer nrog ob coils, yog hais tias lub peev xwm induced nyob rau hauv ib qho instant muaj tib txoj kev, nws yog hu ua tib polarity los yog rho polarity, txwv tsis pub nws yog ntxiv polarity. Cov pab pawg sib txuas ntawm cov hluav taws xob hloov hluav taws xob yog ib qho tseem ceeb ntawm cov hluav taws xob hloov hluav taws xob, thiab nws yog ib qho tseem ceeb rau kev ua haujlwm sib luag ntawm cov hluav taws xob transformers, uas yuav tsum tau ntsuas ntau zaus.
1. Lub hom phiaj thiab qhov tseem ceeb ntawm lub hwj chim transformer polarity pawg thiab qhov ntsuas qhov ntsuas voltage
Nyob rau hauv cov xwm txheej tsis muaj kev ua haujlwm ntawm lub zog hloov hluav taws xob, qhov sib piv ntawm qhov hluav taws xob ntawm high-voltage winding mus rau qhov hluav taws xob ntawm qhov hluav taws xob qis winding yog hu ua qhov kev hloov pauv ntawm lub zog transformer:
K=U 1 /U 2
Qhov voltage piv feem ntau xam raws li kab voltage, uas yog ib qho tseem ceeb Performance index ntawm lub hwj chim transformer. Lub hom phiaj ntawm kev ntsuas qhov kev hloov pauv ntawm lub zog transformer yog:
1. Xyuas kom meej tias qhov voltage piv ntawm txhua tus kais ntawm lub winding nyob rau hauv lub technically tso cai;
2. Txheeb xyuas qhov tseeb ntawm qhov hloov pauv winding;
3. Txiav txim siab seb cov kev coj ntawm txhua tus kais ntawm lub tshuab winding thiab cov kais hloov pauv tau txuas nrog raug.
2. Kev sim txoj kev rau pawg polarity thiab voltage piv ntawm lub hwj chim transformer
1. DC txoj kev txiav txim siab polarity ntawm lub hwj chim transformers
Muaj DC txoj kev thiab AC txoj kev ntsuas lub polarity ntawm lub hwj chim transformer windings.
DC txoj kev: Txuas lub roj teeb qhuav rau lub high-voltage davhlau ya nyob twg ntawm lub hwj chim transformer, txuas ib milliammeter los yog microammeter mus rau lub thib ob sab ntawm lub hwj chim transformer, thiab saib lub viav vias kev taw qhia ntawm lub koob thaum lub roj teeb hloov yog kaw thaum lub sij hawm sim. Txiav txim qhov polarity.
2. Txiav txim siab pab pawg ntawm cov hluav taws xob hloov hluav taws xob los ntawm DC txoj kev;
3. Siv ZSBC-VI tsis siv neeg transformation ratio pawg tester los ntsuas qhov kev hloov pauv.
3. Kev ceev faj thiab kev soj ntsuam cov txiaj ntsig
1. Thaum txiav txim siab polarity los ntawm DC txoj kev, cov txheej txheem xeem yuav tsum tau rov ua dua ob peb zaug kom tsis txhob muaj qhov tsis ncaj ncees lawm vim yog lub viav vias ceev ntawm lub moos.
2. Thaum ntsuas pab pawg, xaiv DC millivoltmeter, microammeter lossis multimeter nrog lub zog hluav taws xob ntau dua thiab ib qho me me rau lub zog hloov hluav taws xob nrog qhov sib piv loj; xaiv qhov hluav taws xob qis dua thiab qhov hluav taws xob ntau dua rau qhov kev hloov pauv me me. Muaj ntau yam millivoltmeter, microammeter lossis multimeter.
3. Qhov kev hloov pauv ntawm lub hwj chim transformer yuav tsum ntsuas nyob rau hauv txhua tus kais. Thaum ntau tshaj ib lub kauj muaj tus kais dej, nws tuaj yeem ntsuas tau ntawm txhua qhov kais dej ntawm txhua lub kauj, thaum lub coil sib txuas yuav tsum ntsuas. txuas nrog tus ntsuas ntsuas.
4. Rau cov khoom siv hluav taws xob tswj hluav taws xob, cov khoom siv hluav taws xob yuav tsum tau siv los hloov thiab coj mus rhaub.
5. Thaum lub sij hawm tag nrho cov txheej txheem ntsuas, tshwj xeeb yuav tsum tau them rau qhov tseeb hais tias lub hwj chim transformers A thiab ib tug tsis tuaj yeem thim rov qab, txwv tsis pub lub high voltage yuav nkag mus rau hauv tus choj lub cev.
6. Thaum qhov ntsuas hluav taws xob maj mam nce, lub hwj huam mov yuav tsum tau muab tua rau kev soj ntsuam thaum lub voltmeter nce mus rau tag nrho cov nplai.
7. Rau qhov ntsuas qhov ntsuas, qhov ntsuas qhov sib piv ntawm txhua tus kais dej yuav tsum yog tib yam li ntawm daim ntawv teev npe; qhov tso cai sib txawv ntawm qhov ntsuas kais voltage piv yog, thiab qhov sib txawv ntawm lwm cov kais dej yuav tsum nyob rau hauv tus nqi impedance ntawm lub hwj chim transformer, tab sis tsis ntau tshaj.
