M'mabwalo, resistors ndi gawo lofunikira lomwe lingathe kuchepetsa kuyenda kwamakono ndikusintha mphamvu zamagetsi kukhala mphamvu zotentha. Pamene magetsi a 380V ndi 220V alumikizidwa ku malekezero onse a resistor, padzakhala kusiyana kwakukulu. Nkhaniyi isanthula kusiyana kumeneku kuchokera kuzinthu zitatu: kusiyana kwa magetsi, kutaya mphamvu, ndi chitetezo.

mawu oyamba:

Ndi kupita patsogolo kosalekeza kwaukadaulo komanso kutukuka kofulumira kwa anthu, mphamvu zamagetsi zakhala zikudziwika paliponse. Mulingo wamagetsi wamagetsi amasiyanasiyananso, pomwe odziwika kwambiri amakhala 380V ndi 220V. Kodi pali kusiyana kotani pakuchita kwa resistor ngati gawo loyambira lamagetsi pamagawo amagetsi awiri?

1, Kusiyana kwa Voltage:

Mphamvu yamagetsi imatanthawuza kusiyana komwe kungathe kuchitika, kuyeza ma volts (V). 380V ndi 220V motsatana amayimira voteji yamagetsi, zomwe zikutanthauza kuti kusiyana kwa voteji pakati pa malekezero awiri a resistor ndikosiyananso muzochitika zonsezi. Malinga ndi lamulo la Ohm, mgwirizano pakati pa voteji ndi panopa ndi U = IR, kumene U ndi voteji, Ine panopa, ndi R ndi kukana. Zitha kuwoneka kuti pansi pa kukana komweko, pamene kulumikizidwa ndi magetsi a 380V, zamakono zidzakhala zazikulu kuposa zomwe zimagwirizanitsidwa ndi magetsi a 220V, chifukwa kusiyana kwa magetsi kumayambitsa kusintha kwamakono. Choncho, pamene gulu lotsutsa likugwirizanitsidwa ndi magetsi omwe ali ndi magetsi osiyanasiyana pamapeto onse awiri, padzakhala kusiyana kwa kukula kwamakono.

2. Kutaya mphamvu:

Mphamvu ndi gawo lofunikira mudera, lomwe limayimira kuchuluka kwa kutembenuka kwa mphamvu pa nthawi iliyonse, kuyesedwa mu ma watts (W). Malinga ndi njira yamphamvu P = IV, pomwe P ndi mphamvu, ine ndi yapano, ndipo V ndi voteji, zitha kudziwika kuti mphamvu imagwirizana ndi zomwe zikuchitika komanso magetsi. Chifukwa chake, pomwe magwero amagetsi osiyanasiyana alumikizidwa kumapeto kwa chopinga, kutayika kwa mphamvu kumasiyananso. Mukalumikizidwa ndi magetsi a 380V, chifukwa chapamwamba kwambiri, kutayika kwa mphamvu kudzawonjezekanso moyenerera; Mukalumikizana ndi magetsi a 220V, chifukwa chazing'ono zamakono, kutaya mphamvu kumakhala kochepa.

3, Chitetezo:

Chitetezo ndichofunikira kwambiri mukamagwiritsa ntchito mabwalo. Mphamvu ya 380V ikalumikizidwa malekezero onse a chotsutsa, kuvulaza kwa thupi la munthu kumachulukirachulukira chifukwa champhamvu yapano. Ngozi zamagetsi zimatha kuvulaza kwambiri kapena kuyika moyo pachiwopsezo. Chifukwa chake, polumikizana ndi magetsi okwera kwambiri, njira zotetezera ziyenera kuchitidwa, monga kapangidwe koyenera, chitetezo chachitetezo, ndi zina zambiri. Mukalumikizana ndi magetsi a 220V, chifukwa chapano pang'ono, chitetezo ndichokwera kwambiri. .

Chidule:

Monga gawo lofunikira pamagawo, zopinga zimatha kukhala ndi zosiyana zikalumikizidwa ndi magwero amagetsi a 380V ndi 220V mbali zonse ziwiri. Mukagwirizanitsa ndi magetsi a 380V, panopa ndipamwamba, kutaya mphamvu kumakhala kwakukulu, ndipo chiopsezo cha chitetezo chikuwonjezeka; Mukalumikizidwa ndi magetsi a 220V, zomwe zikuchitika pano ndizochepa, kutayika kwamagetsi kumakhala kochepa, ndipo chitetezo chimakhala chokwera. Chifukwa chake, popanga mabwalo, ndikofunikira kusankha ma voliyumu osiyanasiyana malinga ndi zosowa zenizeni ndikutengera chitetezo chofananira panthawi yomwe mukugwiritsa ntchito kuti muwonetsetse kuti dera ndi chitetezo chamunthu chikuyenda bwino.

Zindikirani: Nkhaniyi ndi yongofotokozera zokhazokha, ndipo zochitika zenizeni ziyenera kuganiziridwa ndi kusamaliridwa potengera zosowa zenizeni komanso kamangidwe kake ka dera.
