Qhov thib ob load ntawm tam sim no transformer ncaj qha cuam tshuam nws txoj haujlwm raug.Feem ntau hais lus, qhov ntau dua qhov kev thauj khoom thib ob, qhov ntau dua qhov yuam kev ntawm lub transformer.Ntev npaum li qhov kev thauj khoom thib ob tsis tshaj qhov chaw tsim khoom tsim tus nqi, cov chaw tsim khoom yuav tsum xyuas kom meej tias qhov yuam kev tsim los ntawm lub tshuab hloov pauv nyob rau hauv nws cov qib raug lossis nyob rau hauv qhov ntau ntawm 10% kev ua yuam kev nkhaus.Sab hauv.Yog li ntawd, thaum lub sij hawm siv ntawm tam sim no transformer, nws cov qhab nia nruab nrab load thiab qhov tseeb theem nrab load yuav tsum paub.Tsuas yog thaum qhov tseeb thib ob load tsawg dua li qhov ntsuas thib ob tuaj yeem ua yuam kev raws li qhov yuav tsum tau ua.
Thaum qhov kev ua yuam kev ntawm qhov tam sim no transformer tshaj tus nqi ntawm cov chaw tsim khoom, nws yuav muaj kev cuam tshuam tsis zoo rau cov khoom siv thib ob xws li kev tiv thaiv relay thiab metering.Compensatory ntsuas yuav tsum tau ua thaum qhov kev ua yuam kev ntawm lub tam sim no transformer tshaj tus nqi ntawm cov chaw tsim tshuaj paus.
(1) Ua kom qhov chaw hla ntu ntawm cov kab txuas txuas txuas ntxiv lossis txo qhov ntev ntawm lub cable.Ua kom qhov chaw hla ntu ntawm cov kab txuas txuas ntxiv ntawm lub voj voog tam sim no lossis txo qhov ntev ntawm lub cable tiag tiag txo qhov impedance ntawm lub voj voog thib ob thiab txo qhov kev thauj khoom thib ob.
(2) Txuas lub kauj kauj ruam thib ob ntawm qhov hloov pauv tam sim no nyob rau hauv series kom muab ob npaug rau lub nra.Qhov thib ob coils ntawm ob theem tam sim no transformers nrog tib transformation piv thiab tib yam ntxwv yog siv nyob rau hauv series.
(3) Ua kom qhov kev hloov pauv ntawm qhov hloov pauv tam sim no lossis siv qhov hloov pauv tam sim no nrog qhov ntsuas thib ob ntawm 1A.Raws li lub hauv paus ntsiab lus hais tias qhov poob ntawm kab yog proportional rau lub square ntawm tam sim no, nws yuav pom tau hais tias qhov poob ntawm txoj kab yuav me me thiab cov zis impedance yuav loj, yog li ntawd lub load nqa lub peev xwm yuav ntxiv dag zog rau.
(4) Txo cov load thib ob.Xaiv ib tug relay nrog ib tug loj qhov chaw tam sim no ntau npaum li sai tau, vim hais tias cov hlau txoj kab uas hla ntawm relay coil nrog ib tug loj qhov chaw tam sim no yog tuab thiab tus naj npawb ntawm lem yog me me, yog li cov impedance kuj yog me me;los yog hloov cov kev sib txuas series ntawm relay coil mus rau ib qho kev sib txuas mus rau ib qho kev sib txuas, vim tias qhov impedance ntawm kev sib txuas ntawm cov impedance yog loj dua qhov kev sib txuas;los yog siv lub microcomputer tiv thaiv ntaus ntawv los hloov lub electromagnetic relay.
Kev ntsuas ntawm rwb thaiv tsev tsis kam ntawm tam sim no transformer
1. Lub hom phiaj ntawm qhov kev xeem
Nws tuaj yeem pom qhov cuam tshuam ntawm kev rwb thaiv tsev tag nrho, xws li damp, av, nkag mus, rwb thaiv tsev tawg, thiab lwm yam, nrog rau cov cua sov hnyav thiab kev laus tsis xws luag.Kev ntsuas qhov rwb thaiv tsev ntawm cov ntaub thaiv npog kawg rau hauv av tuaj yeem tshawb pom cov dej nkag thiab cov dej tsis haum ntawm lub capacitive tam sim no transformer.
2. Kev ntsuas qhov ntsuas
Ntsuas qhov rwb thaiv tsev tsis kam ntawm thawj winding mus rau theem nrab winding thiab lub casing, thiab cov rwb thaiv tsev tsis kam ntawm txhua qhov thib ob winding thiab casing.
Txhawm rau ntsuas qhov rwb thaiv tsev ntawm cov thawj winding qhov chaw, tab sis nws tsis yog yuav tsum tau ntsuas thaum nws tsis tuaj yeem ntsuas vim yog vim li cas ntawm cov qauv.
Ntsuas qhov rwb thaiv tsev tsis kam ntawm cov ntaub thaiv npog kawg ntawm lub capacitive tam sim no transformer.

3. Kev xaiv cov khoom siv
Ntsuas cov rwb thaiv tsev tiv thaiv ntawm lub ntsiab rwb thaiv tsev ntawm tam sim no transformer, kawg daim ntaub thaiv npog, qhov thib ob winding thiab hauv av.Rwb thaiv tsev tiv thaiv tester ntawm 2500V thiab siab dua yuav tsum tau siv rau kev saib xyuas lossis kev xa mus kuaj thiab kev tiv thaiv.
4. Kev ntsuam xyuas qhov pheej hmoo thiab kev ntsuas ntsuas
tiv thaiv kom poob ntawm qhov siab
Tiv thaiv kev raug mob los ntawm cov khoom poob
tiv thaiv hluav taws xob poob siab
Ua ntej tshem tawm thiab txuas cov kab xeem, transformer nyob rau hauv kev sim yuav tsum tau muab tso rau hauv av kom tsis txhob muaj qhov seem seem thiab induced voltage los ntawm kev ua phem rau tib neeg thiab cuam tshuam rau kev ntsuas.Cov hlau casing ntawm cov ntsuas ntsuas yuav tsum tau ntseeg siab hauv av, thiab cov neeg ntsuas kev khiav hauj lwm cov cuab yeej yuav tsum tau sawv ntawm ib qho insulating ncoo los yog hnav ib qho insulating slash los khiav lub ntsuas.Kev ntsuas cov ntiv tes yuav tsum tau koom tes nrog tus neeg saib xyuas, thiab tsis pub hla kev ua haujlwm.
Teeb cov chaw kaw nyob ib ncig ntawm qhov chaw sim, dai "stop, high voltage txaus ntshai" cov paib, thiab ntxiv dag zog rau kev saib xyuas.Txhim khu kev saib xyuas thiab siv lub tshuab hu nkauj hauv kev ua haujlwm.
5. Kev npaj ua ntej kev xeem
Nkag siab txog cov xwm txheej hauv cheeb tsam thiab kev sim ntawm cov cuab yeej hauv kev sim.
Ua kom tiav cov khoom siv kuaj thiab cov khoom siv
Siv kev nyab xeeb thiab kev ntsuas kev ntsuas ntawm qhov chaw sim
Cov neeg kuaj lub thawv yuav tsum piav qhia cov ntsiab lus ua haujlwm, qhov chaw nyob, ntsuas kev nyab xeeb ntawm qhov chaw, cov ntsiab lus txaus ntshai ntawm kev ua haujlwm ntawm qhov chaw, thiab qhia meej txog kev faib ua haujlwm thiab cov txheej txheem xeem.
6. Teb cov kauj ruam thiab cov kev cai
Txheeb xyuas lub megohmmeter nws tus kheej ua ntej qhov kev xeem, muab lub megohmmeter theem stably, thawj zaug luv luv-circuit test thiab tom qab ntawd qhib-circuit test, thaum txuas nrog lub hwj chim mov ntawm rectified voltage megohmmeter, cov hlau ntawm Uno yuav luv luv Circuit Court "L" thiab "E" lub davhlau ya nyob twg, qhov taw qhia yuav tsum xoom; thaum nws qhib, thaum lub hwj chim qhib lossis qhov ntsuas ceev tau qhia hauv megohms, qhov taw qhia yuav tsum yog "∞". thiab ces txuas lub high voltage davhlau ya nyob twg.
Lub davhlau ya nyob twg "E" ntawm lub megohmmeter yog lub hauv av davhlau ya nyob twg ntawm cov khoom xeem, uas yog tus ncej zoo, thiab "L" yog lub high-voltage davhlau ya nyob twg ntawm cov khoom xeem, uas yog tus ncej tsis zoo."G" txuas nrog lub tshav dav hlau tiv thaiv, uas yog tus ncej tsis zoo.
7. Rwb thaiv tsev tsis kam kuaj
Ntsuas qhov rwb thaiv tsev tsis kam ntawm thawj winding ntawm tam sim no transformer mus rau theem nrab winding thiab lub plhaub
Ntsuas qhov rwb thaiv tsev tsis kam ntawm qhov nruab nrab winding ntawm tam sim no transformer thiab hauv av
