Txoj Cai
Thaum lub voltage transformer nyob rau hauv ib txwm ua hauj lwm, peb-theem voltage ntawm lub hwj chim system yog symmetrical, thiab cov sum ntawm peb-theem induced electromotive quab yuam ntawm lub thib peb kauj yog xoom.Thaum cov av ib-theem tshwm sim, qhov nruab nrab ntawm qhov chaw yuav raug tshem tawm, thiab xoom-sequence voltage yuav tshwm sim ntawm cov terminals ntawm qhib daim duab peb sab los ua tus relay act, yog li tiv thaiv lub hwj chim system.Thaum xoom-sequence voltage tshwm nyob rau hauv lub kauj, xoom-sequence magnetic flux yuav tshwm sim nyob rau hauv cov hlau core.Txog rau qhov kawg no, peb-theem voltage transformer txais ib sab yoke core (thaum 10KV thiab qis dua) lossis peb-theem voltage transformers.Rau hom kev hloov pauv no, qhov tseeb ntawm qhov thib peb kauj tsis yog siab, tab sis nws yuav tsum muaj qee yam kev ua haujlwm dhau los (uas yog, thaum thawj qhov hluav taws xob nce, qhov sib nqus flux ntom ntom hauv cov tub ntxhais hlau kuj nce los ntawm kev sib txuam ntau yam tsis muaj kev puas tsuaj).
Vim li cas koj thiaj li yuav tsum tau hloov qhov voltage ntawm kab?Qhov no yog vim hais tias raws li qhov sib txawv ntawm lub zog tsim hluav taws xob, kev sib kis thiab kev siv hluav taws xob, qhov hluav taws xob ntawm cov kab sib txawv ntawm qhov sib txawv, thiab qhov sib txawv yog qhov sib txawv heev.Qee qhov qis-voltage 220V thiab 380V, thiab qee qhov muaj qhov hluav taws xob siab kaum tawm txhiab tus volts lossis txawm ntau pua txhiab volts.Txhawm rau ntsuas ncaj qha rau cov hluav taws xob qis thiab qhov hluav taws xob siab, nws yog ib qho tsim nyog yuav tsum ua kom cov khoom siv hluav taws xob tsawg thiab cov hluav taws xob siab thiab lwm yam twj paj nruag thiab relays raws li qhov loj ntawm cov kab hluav taws xob.Qhov no yuav tsis tsuas yog ua rau muaj teeb meem loj rau kev tsim cov cuab yeej, tab sis qhov tseem ceeb tshaj, nws tsis tuaj yeem ua tsis tau thiab txwv tsis pub ncaj qha mus rau qhov ntsuas hluav taws xob thiab ntsuas qhov hluav taws xob ncaj qha rau ntawm cov kab hluav taws xob siab.
Cov kev ceev faj
1. Ua ntej lub tshuab hluav taws xob hluav taws xob tau muab tso rau hauv kev ua haujlwm, kev sim thiab tshuaj xyuas yuav tsum tau ua raws li cov khoom tau teev tseg hauv cov kev cai.Piv txwv li, ntsuas polarity, kev sib txuas pab pawg, co rwb thaiv tsev, nuclear theem sib lawv liag, thiab lwm yam.
2. Kev xaim ntawm qhov hluav taws xob hloov hluav taws xob yuav tsum xyuas kom meej nws qhov tseeb.Tus thawj winding yuav tsum tau txuas nrog nyob rau hauv parallel nrog lub Circuit Court nyob rau hauv kev ntsuam xyuas, thiab lub thib ob winding yuav tsum tau kev cob cog rua nyob rau hauv parallel nrog lub voltage coil ntawm kev cob cog rua ntsuas ntsuas, relay tiv thaiv ntaus ntawv los yog tsis siv neeg ntaus ntawv.Nyob rau tib lub sijhawm, kev saib xyuas yuav tsum tau them rau qhov tseeb ntawm polarity..
3. Lub peev xwm ntawm lub load txuas nrog rau sab thib ob ntawm lub tshuab hluav taws xob hloov hluav taws xob yuav tsum tsim nyog, thiab cov khoom txuas nrog rau sab thib ob ntawm lub tshuab hluav taws xob hloov hluav taws xob yuav tsum tsis txhob tshaj nws cov peev txheej, txwv tsis pub, qhov yuam kev ntawm lub transformer yuav nce, thiab nws yog qhov nyuaj kom ua tiav qhov tseeb ntawm qhov ntsuas.
4. Tsis pub luv luv Circuit Court nyob rau theem nrab ntawm qhov voltage transformer.Txij li thaum lub impedance nyob rau hauv lub voltage transformer yog heev me me, yog hais tias lub thib ob Circuit Court yog luv luv, ib tug loj tam sim no yuav tshwm sim, uas yuav ua rau lub thib ob cov khoom puas thiab txawm muaj kev ruaj ntseg ntawm tus kheej.Lub tshuab hluav taws xob hloov hluav taws xob tuaj yeem nruab nrog lub fuse nyob rau sab thib ob los tiv thaiv nws tus kheej los ntawm kev puas tsuaj los ntawm lub voj voog luv luv ntawm ob sab.Yog tias ua tau, fuses yuav tsum tau muab tso rau ntawm thawj sab los tiv thaiv cov hluav taws xob hluav taws xob hluav taws xob los ntawm kev ua phem rau kev nyab xeeb ntawm thawj qhov system vim qhov tsis ua haujlwm ntawm lub tshuab hluav taws xob hluav taws xob los yog cov hlau lead.
5. Txhawm rau kom muaj kev nyab xeeb ntawm tib neeg thaum kov cov ntsuas ntsuas thiab cov relays, qhov thib ob winding ntawm voltage transformer yuav tsum tau grounded ntawm ib qho chaw.Vim hais tias tom qab grounding, thaum lub rwb thaiv tsev ntawm lub hauv paus thiab theem nrab windings puas lawm, nws muaj peev xwm tiv thaiv tau lub siab voltage ntawm lub twj paj nruag thiab relay los ntawm kev ua phem rau tus kheej kev nyab xeeb.
6. luv luv Circuit Court yog kiag li tsis tso cai nyob rau theem nrab ntawm lub voltage transformer.
