Nyob rau hauv lub zog hluav taws xob niaj hnub nimno network, txhua theem {- los ntawm tiam kom tau txais kev xa mus {} Qhov no ua kom meej meej ruaj khov, muaj zog, thiab kev ua haujlwm nyab xeeb. Nkawv siab nyob rau hauv high - voltage Systems feem ntau ncav cuag ob peb txhiab amperes, ua ncaj qha ntsuas nrog cov twj paj nruag tsis yooj yim sua. Yog li no, cov hloov pauv tam sim no tau siv los nyab xeeb thiab muaj tseeb hloov cov dej ntws. Cov hloov pauv tam sim no ua raws li "sensors" thiab "tus saib xyuas" ntawm lub zog hluav taws xob. Lawv hloov pauv siab rau hauv cov qauv, muaj kev nyab xeeb qis qis, muab cov ntaub ntawv raug rau metering, tshuaj xyuas, thiab cov khoom siv tiv thaiv. Nyob rau tib lub sijhawm, lawv cais tawm ntau qhov hluav taws xob, tiv thaiv ob tus neeg ua haujlwm thiab khoom siv. Lawv qhov kev ua tau zoo thiab siv tau kom raug rau kev ntseeg tau thiab kev khwv nyiaj txiag ntawm lub zog hluav taws xob. Kab lus no yuav qhia cov qauv, kev cai, muaj nuj nqi, ntawv thov, xaiv, siv thiab kho cov kev hloov pauv tam sim no.
Tam sim no hloov pauv hloov pauv thiab cov kab ke ua haujlwm
Lub tsev: Ib qho hloov pauv tam sim no muaj cov hlau ua ke, muaj lub tshuab winding, muaj qhov kev txhawb nqa theem nrab, cov lus tsis txaus siab, thiab yeem) cov windings.

Yuav ua li cas xaiv ib qho hloov pauv tam sim no
|
1. Volfage thiab xaiv tam sim no - Cov ntsuas hluav taws xob ntawm ib qho hloov pauv tam sim no yuav tsum tsis txhob qis dua li cov hluav taws xob ntawm lub Circuit Court ntawm lub installate. -} Cov rated tam sim no ntawm thawj qhov cua txawv (piv txwv li 5a, 15a, 20a, 20a... 1500 a). Thaum xaiv cov hloov hluav taws xob tam sim no, cov qhab nia tseem ceeb tam sim no tau pom zoo tam sim no ntawm kev sib dhos tam sim no ntawm 5A, nrog ob peb lub sijhawm thauj khoom tam sim no. 2. Xaiv cov qhab nia raug - Tus hloov pauv tam sim no yuav tsum tau raws li cov cai kawm kom raug. Ntawd yog, nws theem theem qub S₂ yuav tsum tsis txhob muaj ntau tshaj li qhov ntsuas cov qib qis theem nrab thauj mus rau qib ntawd: S₂ₙ> S₂ |

Yuav ua li cas siv tus hloov pauv tam sim no kom raug
1. Cov sab thib ob yuav tsum tsis txhob qhib - circuited
Yog hais tias lub voj voog theem ob tau raug txiav tawm thaum lub sijhawm ua haujlwm, qhov ua rau voltage nyob rau sab nraud yuav nce ntau yam ntxiv hauv kev sib nqus flux. Qhov no tuaj yeem nyeem cov tub ntxhais thiab tsim kom muaj siab- voltage spikes, muaj kev puas tsuaj rau kev ntsuas ntsuas thiab cov neeg ua haujlwm. Yog tias muaj ib sab theem nrab qhib Circuit Court yog kuaj pom, lub Circuit Court yuav tsum raug kaw tam sim ntawd thiab tus txhaum kho.
2. Load txuam thiab kev tiv thaiv
Thaum xaiv cov hloov pauv tam sim no, xav txog cov cuab yeej tawm tswv yim, thiab lwm yam kev tiv thaiv rov qab cuam tshuam nrog, thiab lwm yam kev tiv thaiv kev cuam tshuam Z_b yog nyob hauv qhov ntsuas ntsuas. Txog kev tiv thaiv cov tshuab xav tau kev kub ceev thiab ntseeg tau, ib qho CT nrog qhov kev tiv thaiv kab ke tsawg- Circuit Court tiv thaiv cov yam ntxwv yog pom zoo.
3. Kev teeb tsa txoj haujlwm thiab kev taw qhia
Qhov kev taw qhia ntawm CT yuav tsum ua kom haum nrog cov kev taw qhia kom tsis txhob muaj theem thim rov qab thiab teeb liab yuam kev. Thaum txhim kho nplhaib lossis lub qhov rais {{{- Hom CTS, xyuas kom cov tub ntxhais ua kom raug ntawm lub sijhawm thiab hauv kev tsim nyog, raws li tau teev tseg hauv kev tsim.
4. Qhov kub thiab cua
Cov khoom siv siab lossis qhov chaw huab cua siab tuaj yeem nce ct kub nce, cuam tshuam tooj liab thiab cov khoom poob hlau. Ua kom zoo cua nyob rau hauv cov khoom siv cov khoom siv, thiab tsis txhob txhim kho lub CT ze rau cov kev ua haujlwm kub muaj zog los xyuas kom ntev.
Txij Nkawm Transformer
Thaum lub sijhawm ua haujlwm, ntawm {{{{{0} Diseitish cov neeg ua haujlwm yuav tsum tau kuaj tam sim no hloov tam sim no kom ntseeg tau tias muaj kev nyab xeeb. Thaum soj ntsuam, them sai sai rau cov ntsiab lus hauv qab no:
1. Tus hloov pauv tam sim no yuav tsum tsis muaj suab nrov txawv txawv lossis hlawv cov ntxhiab tsw.
2. Tshawb xyuas cov chaw hloov pauv tam sim no rau overheating.
3. Lub plooj (porcelain rwb thaiv tsev ntawm cov hloov pauv tam sim no yuav tsum yog huv thiab tsis huv, pub dawb ntawm cov kab nrib pleb thiab tawm.
4. Tshawb xyuas cov roj hloov roj hloov tam sim no rau kev ua haujlwm ib txwm muaj thiab tsis muaj roj xau.
5. Nquag sim cov rwb thaiv tsev cov khoom ntawm cov roj hloov roj hloov tam sim no. Rau roj -} Cov hloov pauv tau tam sim no, cov roj zoo yuav tsum tau ua kom tsis txhob muaj peev xwm los tiv thaiv kev ua kom muaj cua sov muaj peev xwm thiab ua rau tawg lossis hluav taws.
