Qhov qhib Circuit Court ntawm kev tiv thaiv winding ntawm tam sim no transformer (CT) yog ib qho teeb meem txhaum cai heev.
Hauv cov ntsiab lus yooj yim, nws yog hais txog: Hauv kev ua haujlwm ib txwm muaj ntawm kev hloov pauv thib ob ntawm lub tshuab tam sim no (piv txwv li, lub voj voog txuas nrog cov cuab yeej tiv thaiv thiab ntsuas ntsuas), nws dheev disconnects, ua rau lub Circuit Court impedance loj heev, yuav luag infinite.
I. Lub hauv paus ntsiab lus tseem ceeb: Kev hloov pauv ntawm "qhov tam sim no" mus rau "siab-voltage source"
1) Thaum lub sijhawm ua haujlwm ib txwm muaj (kaw Circuit Court):
Tam sim no transformer yog qhov tseem ceeb ntawm "tam sim no qhov chaw". Tam sim no nyob rau hauv thawj sab (high tam sim no) txiav txim siab tam sim no nyob rau theem nrab (tsawg tam sim no).
Raws li lub hauv paus ntsiab lus ntawm transformer: I₁ / I₂=N₂ / N₁ (transformer ratio), I₂ raug txwv rau tus nqi ntsuas (feem ntau yog 5A lossis 1A). Lub impedance ntawm theem nrab Circuit Court yog tsawg heev, yog li txawm hais tias tam sim no loj heev, raws li U=I × Z, qhov nruab nrab voltage U yog tsawg heev (feem ntau tsawg tshaj li ob peb volts).
2) Thaum qhib Circuit Court tshwm sim:
Thaum lub Circuit Court raug txiav, lub impedance Z yuav loj heev (mus txog infinity).
Txhawm rau tswj cov electromagnetic induction, cov hlau nplaum sib nqus hauv cov tub ntxhais hlau ntawm lub tam sim no transformer yuav nce sharply, sim tswj cov theem nrab tam sim no I₂.
Raws li cov qauv U₂=I₂ × Z, thaum Z yog qhov loj heev, qhov hluav taws xob siab heev (tus nqi ncov tuaj yeem ncav cuag ntau txhiab lossis kaum txhiab tus volts) yuav raug ntxias ntawm ob sab ntawm qhov qhib qhov taw tes (peak voltage tuaj yeem ua tau ob peb zaug lossis txawm kaum ntawm lub sijhawm ntawm qhov qub voltage).
Lub sijhawm no, tam sim no transformer hloov los ntawm "tam sim no qhov chaw" mus rau qhov txaus ntshai "siab-voltage source".
2 .Qhov tshwm sim loj tshwm sim
Lub siab voltage thiab siab zog generated thaum qhib Circuit Court tuaj yeem ua rau muaj teeb meem loj:
1) Kev nyab xeeb ntawm tus kheej:
Lub siab tsis tshua muaj hluav taws xob muaj peev xwm tawg tau los ntawm huab cua thiab ua rau muaj hluav taws xob poob rau cov neeg ua haujlwm nyob ze. Qhov no yog qhov ncaj ncees thiab txaus ntshai tshaj plaws.
2) khoom puas tsuaj:
Rwb thaiv tsev tawg: Qhov hluav taws xob siab tuaj yeem tawg los ntawm kev rwb thaiv tsev ntawm cov tam sim no transformer windings, rwb thaiv tsev ntawm cov xov hluav taws xob thib ob, thiab cov rwb thaiv tsev ntawm cov khoom siv tiv thaiv kev sib txuas thiab ntsuas ntsuas, ua rau cov khoom puas tsuaj tas mus li.
Core saturation thiab overheating: Ib tug ntse nce nyob rau hauv sib nqus flux yuav ua rau cov tub ntxhais yuav tsum tau heev saturated, generating loj hysteresis thiab eddy tam sim no poob, ua rau hnyav overheating ntawm cov tub ntxhais, uas yuav hlawv tawm tam sim no transformer thiab txawm ua rau hluav taws.
Arc txaus ntshai: Qhov qhib Circuit Court taw tes yuav ua kom muaj qhov nruam arc, igniting flammable cov ntaub ntawv nyob ib ncig ntawm.
3) Kev tiv thaiv tsis ua haujlwm:
Qhib Circuit Court ntawm kev tiv thaiv winding yuav tiv thaiv cov khoom tiv thaiv relay (xws li kev tiv thaiv sib txawv, kev tiv thaiv overcurrent) los ntawm kev txais cov teeb liab tam sim no, ua rau kev tiv thaiv tsis ua haujlwm thaum muaj kev txhaum tiag tiag hauv lub cev, tsis tuaj yeem txiav tawm qhov txhaum, thiab tej zaum yuav ua rau lub zog loj dua lossis cov khoom puas tsuaj.
4) Tsim kom muaj kev phom sij siab - zaus oscillations:
Lub high voltage generated thaum lub sij hawm qhib Circuit Court yuav muaj nplua nuj harmonics thiab siab - zaus oscillations. Cov oscillating voltages no tuaj yeem ua ke rau cov kab ke thib ob lossis lwm yam khoom siv los ntawm cov khoom siv hluav taws xob, ua rau muaj kev cuam tshuam lossis kev puas tsuaj.
3.Yuav ua li cas txheeb xyuas qhib Circuit Court ntawm tam sim no transformer?
Cov neeg ua haujlwm lossis cov neeg ua haujlwm saib xyuas yuav tsum tau ua tib zoo saib xyuas cov xwm txheej hauv qab no:
Lub suab txawv txav: Tam sim no transformer nws tus kheej emits lub zog "buzzing" los yog "squeaking" tawm suab.
Cov cuab yeej tiv thaiv tsis zoo: Cov ntsuas ntsuas tam sim no, lub ntsuas hluav taws xob qhia xoom lossis txawv txav txawv txav; cov cuab yeej tiv thaiv tej zaum yuav ua rau "TA disconnection" los yog lub tswb zoo sib xws.
Haus luam yeeb los yog hlawv tsis hnov tsw: muaj pa taws, sparks, los yog burnt rwb thaiv tsev tsis hnov tsw ntawm lub tam sim no transformer los yog lwm yam terminal block.
4. Kho cov kauj ruam tom qab nrhiav tau qhib Circuit Court (Kev nyab xeeb ua ntej!)
Yog tias nws xav tias lossis paub tseeb tias muaj CT qhib Circuit Court, nws yuav tsum tau ua tam sim ntawd raws li cov hauv qab no:
1) Qhia tam sim: Qhia rau tus xa thiab cov neeg muaj feem cuam tshuam.
2) Kev sib cais kev nyab xeeb: Raws li txoj kev npaj xwm txheej ceev, thov rau cov hluav taws xob hluav taws xob ntawm cov khoom siv tseem ceeb (xws li cov kab hluav taws xob, cov kab).
3) Hnav PPE: Thaum tuav, yuav tsum hnav cov hnab looj tes insulating thiab tsom iav, sawv ntawm ib qho ntaub qhwv insulating.
4) luv- kev kho hluav taws xob: Yog tias nws tuaj yeem ua luv luv -circuit ntawm qhov chaw nyab xeeb (xws li qhov txuas txuas ntawm lub tshuab hluav taws xob tam sim no nws tus kheej), siv luv luv -circuiting clips lossis insulated xov hlau kom ntseeg tau luv luv -circuit thib ob winding.
Lus Cim: luv-circuit ua ntej, tom qab ntawd tuav qhov qhib Circuit Court taw tes; tom qab tuav, ua ntej tshem tawm qhov qhib Circuit Court, tom qab ntawd tshem tawm qhov luv - kab hluav taws xob. Cov kab ke yuav tsum tsis yog yuam kev.
5) Tshawb xyuas thiab kho: Txheeb xyuas qhov qhib qhov taw qhia (xws li cov khoom siv xoob xoob, cov xaim tawg), kho tom qab kuaj xyuas cov rwb thaiv tsev, thiab tsuas yog rov pib dua lub zog tom qab lees paub tias tsis muaj qhov yuam kev.
6) nruj me ntsis txwv tsis pub lub qhov muag tsis pom kev ua haujlwm: txwv tsis pub kov lub qhib Circuit Court yam tsis muaj hluav taws xob hluav taws xob lossis hluav taws xob luv luv -circuit. Txwv tsis pub siv cov xov hlau los yuam kev txuas rau qhib Circuit Court, nyob sib cuag.
Qhov qhib Circuit Court ntawm kev tiv thaiv winding ntawm tam sim no transformer yog ib tug txaus ntshai txhaum uas hloov los ntawm ib tug tsawg-voltage me- lub xeev tam sim no mus rau ib tug siab -voltage loj- lub zog lub xeev. Qhov kev pheej hmoo tseem ceeb yog tus kheej hluav taws xob poob siab, ua raws li cov khoom siv hluav taws xob thiab kev tiv thaiv tsis ua haujlwm. Kev tuav cov kev ua txhaum cai no yuav tsum ua raws li cov cai tswj kev nyab xeeb, ua qhov tseem ceeb ntawm kev siv hluav taws xob, thiab ua kom muaj kev ntseeg siab luv luv -circuiting thaum siv kev tiv thaiv tus kheej. Tus yuam sij rau kev tiv thaiv yog nyob rau hauv tsis tu ncua xyuas qhov nruj thiab rwb thaiv tsev mob ntawm lub thib ob Circuit Court thaiv.
