Khoom nta thiab Txoj Cai
LCWD-35 tam sim no transformer yog compact, me me thiab lub teeb nyob rau hauv hnyav.Lub sab sauv ib nrab yog thawj winding, ib nrab qis yog qhov thib ob winding, lub bushing yog tsau rau ntawm lub hauv paus, lub sab saum toj ntawm lub bushing yog nruab nrog ib tug roj conservator, thawj winding yog coj tawm ntawm ob sab ntawm lub txee phab ntsa, thiab qhov pib davhlau ya nyob twg cim P1 Lub tes tsho me me plooj (porcelain) yog siv los thaiv cov phab ntsa txee, thiab qhov kawg P2 yog txuas ncaj qha rau ntawm phab ntsa txee.Lub hauv ntej ntawm cov roj conservator yog nruab nrog cov roj ntsuas ntsuas qhov ntsuas kub sib txawv.
Txoj Cai:
Nyob rau hauv cov kab ntawm lub zog tsim, substation, kis tau tus mob, faib thiab noj, tam sim no nws txawv heev, xws li los ntawm ob peb amperes mus rau kaum tawm txhiab amperes.Txhawm rau ua kom yooj yim rau kev ntsuas, kev tiv thaiv thiab kev tswj hwm, nws yuav tsum tau hloov mus rau hauv ib qho kev sib txuam tam sim no.Tsis tas li ntawd, qhov hluav taws xob ntawm txoj kab yog feem ntau kuj siab, xws li kev ntsuas ncaj qha, uas yog qhov txaus ntshai heev.Tam sim no transformer plays lub luag haujlwm ntawm kev hloov pauv tam sim no thiab kev sib cais hluav taws xob.
Rau pointer-hom ammeters, feem ntau ntawm cov theem nrab ntawm cov tam sim no transformers yog nyob rau hauv lub ampere theem (xws li 5A, thiab lwm yam).Rau cov cuab yeej digital, cov qauv ntsuas feem ntau yog nyob ntawm qib milliamp (0-5V, 4-20mA, thiab lwm yam).Qhov thib ob tam sim no ntawm qhov me me tam sim no transformer yog milliampere, uas feem ntau ua raws li tus choj ntawm qhov loj transformer thiab cov qauv.
Miniature tam sim no transformers tseem hu ua "instrument tam sim no transformers".("Cov cuab yeej tam sim no transformer" muaj lub ntsiab lus tias nws yog ib qho kev sib piv tam sim no precision tam sim no transformer siv nyob rau hauv lub chaw soj nstuam, uas feem ntau yog siv los nthuav cov ntsuas ntau yam.)
Zoo ib yam li transformer, tam sim no transformer kuj ua haujlwm raws li lub hauv paus ntsiab lus ntawm electromagnetic induction.Lub transformer transforms qhov voltage thiab tam sim no transformer transforms tam sim no.Lub winding ntawm tam sim no transformer txuas nrog ntsuas tam sim no (tus naj npawb ntawm lem yog N1) yog hu ua thawj winding (los yog thawj winding, thawj winding);lub winding txuas nrog lub ntsuas ntsuas (tus naj npawb ntawm lem yog N2) yog hu ua Secondary winding (los yog theem nrab winding).winding, thib ob winding).
Tam sim no tus piv ntawm thawj winding tam sim no I1 mus rau theem nrab winding I2 ntawm lub tam sim no transformer yog hu ua qhov tseeb tam sim no piv K. Qhov tam sim no piv ntawm tam sim no transformer thaum nws ua hauj lwm nyob rau hauv lub rated tam sim no hu ua qhov ntsuas tam sim no piv ntawm tam sim no transformer. , hais los ntawm Kn.
Kn = I1n/I2n
Kev ua haujlwm ntawm tam sim no transformer (CT rau luv luv) yog los hloov cov thawj tam sim no nrog tus nqi loj dua rau hauv qhov thib ob tam sim no nrog tus nqi me dua los ntawm qee qhov kev hloov pauv, uas yog siv rau kev tiv thaiv, ntsuas thiab lwm yam.Piv txwv li, tam sim no transformer nrog tus piv ntawm 400/5 tuaj yeem hloov qhov tam sim no ntawm 400A mus rau qhov tam sim no ntawm 5A.
Transformer Teebmeem Kev Tswj thiab kev txiav txim
Kev daws teeb meem ntsig txog Transformer:
Tam sim no transformer tsis ua hauj lwm feem ntau nrog lub suab thiab lwm yam tshwm sim.Thaum lub thib ob Circuit Court qhib dheev, lub siab induced muaj peev xwm yog generated nyob rau hauv lub thib ob kauj, thiab nws lub ncov tus nqi tuaj yeem ncav cuag ntau tshaj li ob peb txhiab volts, uas ua rau muaj kev phom sij rau lub neej ntawm cov neeg ua haujlwm thiab kev nyab xeeb ntawm cov khoom siv ntawm lub voj voog thib ob, thiab high voltage yuav ua rau hluav taws kub.Nyob rau tib lub sijhawm, vim qhov nce ntxiv ntawm cov hlau nplaum sib nqus hauv cov tub ntxhais hlau, nws nce mus txog lub xeev siab saturation.Cov tub ntxhais poob thiab cua sov yog qhov hnyav, uas tuaj yeem ua rau lub rheological theem nrab winding.Lub sijhawm no, cov nthwv dej uas tsis yog-sinusoidal yog tshwm sim los ntawm qhov nce ntawm qhov sib nqus flux ntom ntom, uas ua rau kev vibration ntawm silicon steel ntawv tsis sib xws, ua rau lub suab nrov.
1. Kev tuav ntawm lub tam sim no transformer nyob rau hauv lub qhib Circuit Court yog hais tias xws li ib tug txhaum tshwm sim, lub load yuav tsum tsis txhob hloov, cov kev tiv thaiv ntaus ntawv uas tej zaum yuav malfunctioning yuav tsum tau deactivated, thiab cov neeg ua hauj lwm yuav tsum tau ceeb toom kom tshem tawm sai sai.
2. Kev kho ntawm tam sim no transformer thib ob Circuit Court disconnection (qhib Circuit Court) 1. Qhov tshwm sim txawv txav:
a.Qhov taw qhia ntawm lub ammeter poob mus rau xoom, qhov taw qhia ntawm cov khoom siv hluav taws xob thiab cov hluav taws xob reactive zog txo qis lossis oscillates, thiab watt-teev meter tig maj mam lossis nres.
b.Differential disconnection teeb ceeb toom.
c.Lub transformer tam sim no ua rau cov suab nrov txawv txav lossis ua kom muaj cua sov, haus luam yeeb lossis tawm ntawm cov terminals thib ob, sparks, thiab lwm yam.
d.Cov khoom tiv thaiv relay tsis kam ua, lossis ua haujlwm tsis zoo (qhov tshwm sim no tsuas yog pom thaum lub Circuit Court breaker mus los ntawm kev ua yuam kev lossis tsis kam mus ncig thiab ua rau muaj kev sib tw dhia).
2. Exception tuav:
a.Tam sim ntawd tshaj tawm cov tsos mob rau lub sij hawm uas nws belongs.
b.Raws li qhov tshwm sim, txiav txim seb qhov tam sim no transformer ntawm kev ntsuas Circuit Court los yog kev tiv thaiv Circuit Court qhib.Deactivation ntawm kev tiv thaiv uas yuav ua rau kev ua haujlwm yuam kev yuav tsum tau txiav txim siab ua ntej muab pov tseg.
c.Thaum kuaj xyuas lub voj voog thib ob ntawm lub tshuab hluav taws xob tam sim no, koj yuav tsum sawv ntawm cov ntaub ntawv insulating, xyuam xim rau tus kheej kev nyab xeeb, thiab siv cov cuab yeej insulating tsim nyog.
d.Thaum lub voj voog thib ob ntawm lub tshuab hluav taws xob tam sim no qhib los ua kom muaj hluav taws kub, lub hwj chim yuav tsum raug txiav tawm ua ntej, thiab tom qab ntawd cov hluav taws yuav tsum tau muab tua nrog cov ntaub asbestos qhuav los yog cov tua hluav taws qhuav.
3. Tam sim no transformer lub cev txhaum thaum lub tam sim no transformer txhaum muaj ib tug ntawm cov nram qab no tej yam kev mob, nws yuav tsum tau nres tam sim ntawd:
a.Muaj lub suab txawv txav thiab overheating sab hauv, nrog rau cov pa taws thiab tsw ntxhiab tsw.b.Cov roj loj heev, cov plooj (porcelain) puas los yog paug tshwm sim.
c.Roj txhaj tshuaj tua hluav taws los yog kua nplaum phenomenon.
d.Lub elongation ntawm cov hlau expander ho ntau tshaj qhov teev tus nqi ntawm ambient kub.
Order plan:
1. Muab cov phiaj xwm kab hluav taws xob, daim ntawv thov thiab cov kab kos duab, ntsuas hluav taws xob, ntsuas tam sim no, thiab lwm yam.
2. Kev tswj hwm, ntsuas thiab tiv thaiv kev ua haujlwm thiab lwm yam khoom siv xauv thiab tsis siv neeg.
3. Thaum lub transformer siv nyob rau hauv tshwj xeeb tej yam kev mob, nws yuav tsum tau piav nyob rau hauv kom meej thaum txiav txim.
4. Thaum xav tau lwm yam khoom siv lossis ntau dua thiab cov khoom seem, yuav tsum tau thov cov hom thiab ntau.
