Lub hauv paus ntsiab lus ntawm kev siv split tam sim no transformers
Apr 12, 2023| 1) Kev xaim ntawm lub tshuab hluav taws xob tam sim no yuav tsum ua raws li lub hauv paus ntsiab lus: uas yog, thawj winding yuav tsum tau txuas nrog lub voj voog nyob rau hauv kev sim, thaum lub thib ob winding yuav tsum tau txuas nrog nyob rau hauv series nrog tag nrho cov ntsuas loads.
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 sij hawm, ib qho kawg ntawm lub thib ob sab yuav tsum tau grounded los tiv thaiv lub high voltage nyob rau hauv lub thawj sab los ntawm kev nkag mus rau lub low voltage sab ntawm lub thib ob sab thaum lub rwb thaiv tsev puas, ua rau tus kheej thiab cov khoom raug mob.
3) Sab nraud yog tsis tso cai rau qhib Circuit Court, vim hais tias thaum lub Circuit Court qhib, tam sim no I1 nyob rau hauv thawj sab yuav ua tus magnetizing tam sim no, ua rau ib tug cia li nce nyob rau hauv φm thiab E2, uas ua rau ntau saturation thiab magnetization ntawm lub hlau core, tsim hluav taws kub hnyav thiab txawm tias hlawv ntawm lub kauj; Nyob rau tib lub sijhawm, tom qab lub tshuab hluav taws xob sib nqus ntau dhau saturated thiab magnetized, nce qhov yuam kev. Thaum lub tam sim no transformer ua hauj lwm ib txwm, lub thib ob sab yog siv nyob rau hauv series nrog tam sim no coils xws li ntsuas ntsuas thiab relays. Lub impedance ntawm tam sim no coils xws li ntsuas ntsuas thiab relays yog heev me me, thiab ob sab yog zoo li ib tug luv luv Circuit Court. Qhov loj ntawm CT thib ob tam sim no yog txiav txim siab los ntawm thawj qhov tam sim no, thiab lub peev xwm sib nqus tsim los ntawm qhov thib ob tam sim no sib npaug ntawm cov peev xwm sib nqus ntawm thawj tam sim no. Yog tias nws qhib tam sim ntawd, lub zog ntawm lub zog hluav taws xob dheev 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 qhov thib ob sab winding yuav ua rau cov nthwv dej siab heev, nws tus nqi tuaj yeem ncav cuag ntau txhiab lossis ntau txhiab tus volts, ua rau muaj kev phom sij rau kev nyab xeeb ntawm cov neeg ua haujlwm thiab kev ua haujlwm rwb thaiv tsev ntawm cov twj paj nruag.
Tsis tas li ntawd, qhov qhib qhov hluav taws xob ntawm qhov chaw nruab nrab ua rau qhov hluav taws xob ntawm qhov nruab nrab mus txog ntau pua volts, uas yuav ua rau muaj hluav taws xob poob siab yog tias kov. Yog li ntawd, qhov thib ob sab ntawm lub tam sim no transformer yog nruab nrog ib tug luv luv-circuit hloov los tiv thaiv lub thib ob sab ntawm qhib. Thaum lub sij hawm siv, ib zaug ob sab yog qhib, lub Circuit Court load yuav tsum tau muab tshem tawm tam sim ntawd, thiab ces yuav tsum tau txiav tawm lub hwj chim. Nws tuaj yeem rov siv dua tom qab txhua yam ua tiav.
4) Txhawm rau ua kom tau raws li qhov xav tau ntawm cov cuab yeej ntsuas, kev tiv thaiv relay, kev txiav txim siab tsis ua haujlwm ntawm Circuit Court thiab kev lim dej tsis raug, thiab lwm yam, teeb tsa 2 mus rau 8 tam sim no transformers nrog cov windings thib ob.
5) Qhov chaw teeb tsa ntawm lub tshuab hluav taws xob tiv thaiv tam sim no yuav tsum tau teeb tsa kom tshem tawm qhov chaw tsis muaj kev tiv thaiv ntawm cov cuab yeej tiv thaiv tseem ceeb kom ntau li ntau tau. 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 yog nyob rau hauv qhov kev tiv thaiv ntawm tus ntoo khaub lig ntau yam.
6) Txhawm rau txo qhov kev puas tsuaj los ntawm kev tsis ua haujlwm ntawm lub tshuab hluav taws xob, lub tshuab hluav taws xob tam sim no siv los hloov kho 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 pab txhawb kev tsom xam thiab nrhiav kev ua txhaum 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.
