Pakatikati pa chingwe chamagetsi chimapangidwa makamaka ndi ma conductor angapo, omwe amagawidwa kukhala pachimake chimodzi, pawiri pachimake ndi atatu pachimake.
Zingwe zapakatikati zimagwiritsidwa ntchito kwambiri pagawo limodzi la AC ndi DC, pomwe zingwe zitatu zazikuluzikulu zimagwiritsidwa ntchito kwambiri mu magawo atatu a AC.
madera.Kwa zingwe zapakati-pachimake, mgwirizano pakati pa mainchesi apakati ndi chingwe chakunja ndi chosavuta.Nthawi zambiri,
waya pachimake awiri ndi za 20% mpaka 30% ya chingwe awiri awiri akunja.Chifukwa chake, titha kuyeza kukula kwapakati poyesa
mbali yakunja ya chingwe.
Kwa zingwe zitatu zazikuluzikulu, popeza magawo atatu apano apanga mphamvu yamaginito mu ma conductor, mphamvu ya danga.
pakati pa conductors ndi insulation layer iyenera kuganiziridwa.Chifukwa chake, powerengera kuchuluka kwa chingwe chakunja,
zinthu monga kondakitala cross-Sectional dera, danga pakati kondakitala ndi makulidwe a kutchinjiriza wosanjikiza kufunika
kuganiziridwa.Nanga bwanji kuwerengera awiri akunja a chingwe?Tiyeni tione m'munsimu.
▌01 Njira yakunja kwa chingwe
Zinthu zotsatirazi ziyenera kuganiziridwa powerengera kukula kwa chingwe chakunja:
1. Kondakitala m'mimba mwake: awiri a kondakitala mkati chingwe;
2. Insulation layer makulidwe: makulidwe a chingwe chotchingira chamkati cha chingwe;
3. Makulidwe a m'chimake: makulidwe a m'chimake chakunja cha chingwe;
4. Chiwerengero cha zingwe za chingwe: chiwerengero cha zingwe zazitsulo mkati mwa chingwe.
Poganizira zomwe zili pamwambazi, njira yotsatirayi ingagwiritsidwe ntchito powerengera kukula kwa chingwe:
M'mimba mwake wakunja = kondakita m'mimba mwake + 2 × insulation wosanjikiza makulidwe + 2 × makulidwe m'chimake
Pakati pawo, m'mimba mwake akunja wochititsa angapezeke mwa kufunsa Buku kapena kuyeza malinga ndi
mawonekedwe a conductor;makulidwe a insulation layer ndi makulidwe a sheath atha kupezeka pofunsira
tsatanetsatane wa chingwe kapena kuyeza.
Tiyenera kuzindikira kuti ndondomeko yomwe ili pamwambayi ikugwira ntchito pazingwe zamtundu umodzi.Ngati ndi chingwe chamitundu yambiri, chiyenera kuwerengedwa molingana
ku formula iyi:
M'mimba mwake wakunja = (m'mimba mwake wakunja wa conductor + 2 × makulidwe otsekera + 2 × makulidwe a sheath) × kuchuluka kwa zingwe + 10%
Powerengera zakunja kwa chingwe chamitundu yambiri, kulolerana kwa 10% kuyenera kuwonjezeredwa pazotsatira.
▌02 Njira zodzitetezera
1. Musanawerengere, muyenera kutsimikizira mozama za chingwe, kondakitala wagawo lagawo ndi zidziwitso zina.
kuonetsetsa kulondola kwa mawerengedwe;
2. Powerengera, ndikofunikira kuganizira momwe chingwecho chimagwiritsidwira ntchito, monga mobisa, pamwamba pa nthaka, pamwamba.
ndi madera ena, chifukwa madera osiyanasiyana ogwiritsira ntchito amafunikira zida zosiyanasiyana za sheath kuti zisankhidwe;
3. Powerengera, muyenera kuganiziranso njira yoyika chingwe, monga chokhazikika kapena chosunthika, chomwe chidzakhudza
kukula ndi kulimba kwamphamvu kwa chingwe;
4. Samalirani kulolerana powerengera zakunja kwa chingwe, ndikusankha ngati kulolera kwina kuyenera kutero.
ziwonjezedwa pazotsatira zowerengera kutengera momwe zinthu ziliri.
Mwachidule, mawerengedwe a m'mimba mwake akunja kwa chingwe amafunikira kulingalira mozama pazinthu zingapo.Ngati simuli
otsimikiza za njira yowerengera kapena magawo, muyenera kufunsa akatswiri kapena kufunsa zambiri zoyenera.
