Cov ntsiab cai ntawm kev siv tam sim no transformers
Jan 23, 2023| 1. Cov xaim hluav taws xob tam sim no yuav tsum ua raws li cov hauv paus ntsiab lus ntawm kev sib txuas: uas yog, ib qho kev sib tw winding yog txuas nrog hauv kev sib txuas nrog lub voj voog nyob rau hauv kev sim, thaum ob winding resistances txuas nrog rau txhua qhov ntsuas ntsuas.
2. Raws li qhov loj ntawm qhov ntsuas tam sim no, xaiv qhov kev hloov pauv tsim nyog, txwv tsis pub qhov yuam kev yuav nce ntxiv.
Nyob rau tib lub sijhawm, ob qhov kawg yuav tsum tau muab tso rau hauv av kom tiv thaiv tau tias thaum lub rwb thaiv tsev puas lawm, ib sab hluav taws xob siab dhau los ua ob sab tsis muaj hluav taws xob, ua rau tus kheej thiab cov khoom siv sib tsoo.
3. Qhov thib ob yog tsis tso cai rau qhib Circuit Court, vim hais tias thaum lub Circuit Court qhib, thawj tam sim no I1 yuav tag nrho ua magnetizing tam sim no, ua rau φm thiab E2 surges, ua rau ntau saturation thiab magnetization ntawm cov tub ntxhais hlau, loj cua sov los yog txawm hlawv ntawm lub kauj, thiab nyob rau tib lub sij hawm lub oversaturated magnetization Lub magnetic circuit tsub kom qhov yuam kev. Thaum tam sim no transformer ua hauj lwm ib txwm, tam sim no coils xws li ntsuas ntsuas thiab relays yog txuas nrog nyob rau hauv series ntawm ob sab. Lub impedance ntawm cov coils tam sim no xws li ntsuas ntsuas thiab relays yog qhov me me, thiab ob sab zoo ib yam li luv luv circuits. Qhov loj ntawm CT thib ob tam sim no yog txiav txim siab los ntawm ib qho tam sim no, thiab ob qhov tam sim no tsim Lub peev xwm sib nqus yog qhov sib npaug ntawm cov peev xwm sib nqus ntawm ib qho tam sim no.
Yog tias nws qhib tam sim ntawd, lub zog ntawm lub zog hluav taws xob hloov pauv los ntawm tus nqi me me mus rau tus nqi loj, thiab cov hlau nplaum sib nqus hauv cov tub ntxhais hlau nthuav tawm cov nthwv dej loj heev, yog li cov windings ntawm ob sab yuav ua rau lub siab ncov nthwv dej thaum lub Sib nqus flux yog xoom, nws tus nqi tuaj yeem ncav cuag ntau txhiab lossis txawm kaum tawm txhiab tus volts, ua rau muaj kev phom sij rau cov neeg ua haujlwm kev nyab xeeb thiab kev rwb thaiv tsev ntawm cov twj paj nruag. Tsis tas li ntawd, qhov qhib hluav taws xob ntawm ob sab ua rau qhov hluav taws xob ntawm ob sab siab txog ntau pua volts, uas yuav ua rau hluav taws xob poob siab thaum lawv kov. Yog li ntawd, tam sim no transformers ntawm ob sab yog nruab nrog luv luv-circuit keyboards los tiv thaiv qhib circuits ntawm ob sab. Thaum siv, cov khoom siv hluav taws xob yuav tsum raug tshem tawm tam sim tom qab ob lub voj voog qhib, thiab tom qab ntawd fais fab tuag. Tom qab txhua yam ua tiav, nws tuaj yeem siv dua.
4. Yuav kom ua tau raws li qhov xav tau ntawm cov cuab yeej ntsuas, kev tiv thaiv relay, Circuit Court breaker txhaum kev txiav txim thiab kev lim dej tsis raug, nruab Muaj 2 ~ 8 qhov hloov pauv tam sim no.
5. Lub installation txoj hauj lwm ntawm kev tiv thaiv tam sim no transformer yuav tsum tau teem kom deb li deb tau raws li qhov tsis muaj kev tiv thaiv cheeb tsam ntawm lub ntsiab tiv thaiv ntaus ntawv. Piv txwv li, yog tias muaj ob pawg ntawm cov transformers tam sim no thiab qhov chaw tso cai, lawv yuav tsum tau nruab rau ntawm ob sab ntawm lub Circuit Court breaker kom lub Circuit Court breaker nyob rau hauv qhov ntau ntawm kev tiv thaiv cross
6. Txhawm rau tiv thaiv lub tsheb npav tsis ua haujlwm los ntawm qhov flashover ntawm lub qhov (socket) ntawm kem tam sim no transformer, qhov tam sim no transformer feem ntau yog teem rau ntawm qhov hluav taws xob ntawm lub Circuit Court breaker los yog sab ntawm lub transformer.
7. Txhawm rau txo qhov kev puas tsuaj los ntawm kev ua txhaum sab hauv ntawm lub tshuab hluav taws xob, lub tshuab hluav taws xob tam sim no siv rau kev hloov kho tsis siv neeg ntawm cov cuab yeej excitation yuav tsum tau teem rau ntawm qhov hluav taws xob sab ntawm lub tshuab hluav taws xob stator winding. Txhawm rau ua kom yooj yim rau kev txheeb xyuas thiab tshawb pom ntawm qhov tsis raug sab hauv ua ntej lub tshuab hluav taws xob tau muab tso rau hauv qhov system, tam sim no transformer siv rau kev ntsuas ntsuas yuav tsum tau nruab rau ntawm qhov nruab nrab ntawm lub tshuab hluav taws xob.
