Foundations of teori Electrical Engineering: Habka of voltages Guntin

voltages Guntin Habka - xisaabinta ah wareeggeedii korontada taas oo qiimaha danab waa qanjidhada silsilado variable qaraabo shirkii salka. isla'egyada waxaa ay diyaarisey ku saleysan ugu horeysay ee sharciga Kirchhoff ee, kaas oo u ogolaanaya si loo yareeyo tirada isleegyo si ay qiimo k-1, halkaas oo k - tirada qanjidhada circuit. Habkani waxaa sida ugu wanaagsan loo isticmaalo marka tirada laamaha Bannaanka ka badan labo ka mid ah. voltages Guntin Habka helay codsiga in computer barnaamijyada thay ee wareeggeedii korontada, ay sabab u tahay sahal of formation of isleegyo kuus kuus geynta.

voltages patrilineal waxaa lagu magacaabaa danab loo aabo yeelin dhexeeya Guntin tixraac (waxaa lagu wadaa in uu eber ka iman kara) iyo mid kasta oo ka mid ah qanjidhada ah. jaantus The matalaan shirka oo taageero ku xeeldheer.

Ka fiirso habab kala duwan oo la xisaabinayo wareeggeedii korontada

Nuxurka habkan kooban yahay in la xaliyo nidaam isleegyo isticmaalaya awoodo goostay oo kasta Guntin circuit ixtiraam leh in ay node tixraaca. Ka dib markii in, wareeggeedii xisaabinta iyadoo la isticmaalayo sharciga Ohm ee, in la go'aamiyo by qiimaha hadda laamaha oo dhan.

wareeggeedii xisaabinta Complex ee isku xigay ee soo socda:

1. Jaantuska compise waxyaabaha oo dhan.

2. Waxaa jiri doona ah Guntin tixraaca loo aabo yeelin. Waxaa intaa dheer, waxaa lagu talinayaa in ay doortaan Guntin ah oo tirada ugu badan laamaha isugu.

3. Hagaaji loo aabo yeelin jihada of hadda ah ee laamaha oo dhan, taas oo muujinaysaa in jaantuska.

4. Wixii xisaabinta ku guuleysan kara mid ah qanjidhada haray eego Guntin ku tixraaca xulay la sameeyo nidaamka isleegyo.

Sinnaanta nidaamka noocan oo kale ah waxay yeelan doonaan foomka soo socda:

U1G11 - U2G12 - ... - UsG1s - UnG1n = Σ1EG + Σ1J

-U1G21 + U2G22 - ... - UsG2s - UnG2n = Σ2EG + Σ2J

........................................................................................

U1Gn1 - U2Gn2 - ... - UsGns + UnGnn = ΣnEG + ΣnJ, halkaas oo:

• G - xaddiga laamaha tabinta xiran Guntin ah;
• U - qiimaha voltages Guntin;
• ΣEG - wadarta aljabrada ee wax soo saarka ee EMF laamihii, kuwaas oo ku xeeran goobta, oo ay conductivity. (In kiiska halkaas oo falal xoog electromotive jihada shirkii halka sheyga waxa lagu qoray a "+" calaamad in kiiska ka soo horjeeda - "-".)

Nidaamka isla'egta kor ku xusan u saamaxaaya in ay si fudud loo xisaabiyo qiimaha loo baahan yahay ee voltages Guntin ah. Waxay leedahay magac - nidaamka isleegyo patrilineal. In kiiska halkaas oo a circuit korontada adag ka kooban yahay tirada n-aad ee qanjidhada loo baahan yahay in la sameeyo isla'egta patrilineal waa mid ka yar tirada qanjidhada. Marka la eego in dhammaan isla'egyada waxaa ku saleysan sharciga ugu horreeyey Kirchhoff ayaa ku qoran, silsiladda xisaabiyaa waa kooban yihiin ilaha kaliya oo madaxbanaan oo hadda korontada. In kiiska halkaas oo circuit wuxuu ka kooban yahay il danab a, waa in la beddalo by dhiganta ilo hadda. Intaa waxaa dheer, isla'egta patrilineal lagu qaab shax ku qoran waxaa laga yaabaa.

5. Nidaamka isla'egyada waxaa xallin waayo, voltages patrilineal, go'aaminta qiimaha ay.

6. Intaas ka dib, waayo, laan kasta, oo dhan qiyamka hadda korontada wareegi waxaa si gaar ah loo xisaabiyaa by sharciga Ohm ee.

I = (ua - Ub + ΣEab) / ΣRab, kuna waari dhexdeeda,

• I - laamaha silsilad qiimaha hadda;
• Ua - iman kara ee Guntin iyo sidoo;
• Ub - iman kara ee Guntin b ah;
• ΣEab - wadarta aljabrada ee laanta;
• ΣRab - wadarta xisaabta ee iska caabin ah ee laanta.

Guntin Habka voltages for wareeggeedii ka kooban laba kiniisadaha

In la xisaabinayo wareeggeedii korontada ay ku jiraan qanjidhada laba kaliya, nidaamka isleegyo ka koobnaan doonaan isla'egta hal, kaas oo ay macquul tahay in si toos ah loo xisaabiyo qiimaha voltages Guntin:

U = (ΣnEnGn + ΣnJn) / ΣmGm, kuna waari dhexdeeda,

• ΣnEnGn - wadarta aljabrada oo ka mid ah waxyaabaha laamaha EMF on conductivity laamaha, kuwaas oo ah;
• ΣnJn - wadarta aljabrada ilaha hadda;
• ΣmGm - wadarta xisaabta ah conductivities ee dhammaan laamaha dhexeeya qanjidhada.

Habka of voltages Guntin ayaa soo socda faa'iidooyinka xisaabeed: fududaato xisaabinta iyo hoos u dhac weyn ee tirada hawlaha xisaabta.
