Madziko ongolankhula ya zamagetsi: njira ya voltages mfundo

voltages njira mfundo - aziwerenga madera magetsi imene mfundo voteji ndi variable mfundo unyolo wachibale khamu m'munsi. maikwezhoni ndi linakonzedwa pa maziko a koyamba lamulo Kirchhoff a, amene amalola kuchepetsa chiwerengero cha maikwezhoni kuti mtengo K-1, kumene K - chiwerengero cha mfundo dera. Njira bwino ntchito pamene nambala ya nthambi ya dera oposa awiri. Njira voltages mfundo anapeza ntchito mu kompyuta mapulogalamu zoyeserera madera magetsi, chifukwa chomasuka mapangidwe maikwezhoni mfundo aligorivimu.

voltages Nodal amatchedwa voteji umasinthasintha pakati pa mfundo Buku (iwo anayamba ziro kuthekera) ndipo aliyense wa mfundo za. The zithunzi kuimira ochirimika thandizo msonkhano.

Taganizirani njira zosiyanasiyana kuwerengetsa madera magetsi

Akamanena za njira imeneyi imakhala kuthetsa dongosolo la maikwezhoni ntchito Zoyenereza anatsimikiza umene aliyense dera mfundo za mfundo kutchulidwa. Pambuyo pake, madera mawerengedwe ntchito malamulo Ohm, kuti anatsimikiza ndi makhalidwe atsopano a nthambi zonse.

Zovuta mawerengedwe madera akuyambira zotsatirazi:

1. compise chithunzi ndi zinthu zonse.

2. Padzakhala wopondereza Buku mfundo. Komanso tikulimbikitsidwa kuti sankhani mfundo imene nambala yaikulu ya nthambi converge.

3. Sankhani umasinthasintha malangizo a mafunde mu nthambi zonse, amene amaimira taperekachi.

4. Kwa mawerengedwe a zimphamvu za mfundo otsala wachibale kutchulidwa mfundo anasankha udayesedwa dongosolo la maikwezhoni.

Kuyanjana pakathi pa dongosolo amenewa amakhala ndi mawonekedwe zotsatirazi:

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

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

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

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

• G - kuchuluka kwa nthambi conduction chikugwirizana ndi mfundo ya;
• U - kufunika voltages mfundo;
• ΣEG - ndi algebraic ndalama pa zinthu za EMF nthambi, amene ali pafupi ndi malo, madutsidwe awo. (Mu choncho kumene electromotive mphamvu zochita malangizo msonkhano pamene mankhwala ulipo ndi "+" chizindikiro pa nkhani zosiyana - "-".)

Pamwamba aone kuti pali dongosolo chimathandiza mosavuta kuwerengetsa makhalidwe ofunikira voltages ndi mfundo. Iye ali dzina - dongosolo la maikwezhoni nodal. Ngati kumene zovuta dera magetsi wapangidwa ndi N-TH chiwerengero cha mfundo m'pofunika kuti anthu aone kuti pali nodal ndi imodzi zosakwana chiwerengero cha mfundo. Popeza kuti maikwezhoni onse olembedwa pa maziko a lamulo loyamba la Kirchhoff ndi unyolo masamu ayenera amapanga magwero basi wosadalira panopa magetsi. Ngati komwe kunali mipingo zizindikiro voteji gwero, ayenera m'malo ndi ofanana magwero panopa. Komanso, aone kuti pali nodal akhoza olembedwa mu mawonekedwe masanjidwewo.

5. dongosolo la maikwezhoni ndi kuthetsedwa kwa voltages nodal, kudziŵa makhalidwe awo.

6. Kenako, kwa nthambi iliyonse, makhalidwe onse a magetsi mu dera ndi masamu padera ndi lamulo Ohm a.

Ine = (Ua - Ub + ΣEab) / ΣRab, m'mene:

• Ine - unyolo nthambi mtengo panopa;
• Ua - kuthekera kwa mfundo komanso;
• Ub - kuthekera kwa B mfundo;
• ΣEab - ndi algebraic Uwerenge nthambi
• ΣRab - masamu Uwerenge kulimbikira nthambi.

Njira mfundo voltages kwa madera ongokhala Misonkhano iwiri

Mu kuwerengetsa madera magetsi kuti muli mfundo ziwiri zokha, kachitidwe ka maikwezhoni adzakhala zigwirizana wa aone kuti pali umodzi, umene n'zotheka kuwerengetsa mwachindunji kufunika voltages mfundo:

U = (ΣnEnGn + ΣnJn) / ΣmGm, m'mene:

• ΣnEnGn - ndi algebraic ndalama pa zinthu za nthambi EMF pa madutsidwe nthambi;
• ΣnJn - algebraic Uwerenge magwero panopa;
• ΣmGm - pa masamu Uwerenge conductivities nthambi zonse pakati pa mfundo.

Njira voltages mfundo ali zotsatirazi ubwino masamu: chomasuka mawerengedwe ndi kuchepetsa kwambiri chiwerengero cha ntchito masamu.
