Kodi zotakataka mphamvu kwaiye

M'mabwalo a AC, mphamvu yamagetsi imabwera chifukwa zinthu zochititsa chidwi kapena za capacitive zimalowetsedwa mudera.Ndiye imakhalapo mu mawonekedwe a mphamvu yogwira ntchito, mphamvu yogwira ntchito, mphamvu yowonekera ndi zina zotero.Kumvetsetsa kosavuta kwa mphamvu zowonongeka ndi kusinthanitsa mphamvu pakati pa magetsi ndi katundu kapena katundu ndi katundu.

Mu dera la sinusoidal AC panopa, pali mitundu itatu ya mphamvu, mphamvu yogwira ntchito, mphamvu yogwira ntchito ndi mphamvu yowonekera.Mphamvu yogwira ntchito;Kuchuluka kwa mphamvu zomwe katundu angapeze.Mphamvu yogwira ntchito;Kuchuluka kwa mphamvu yomwe imachepetsedwa ndi kusamutsa mphamvu yotulutsa mphamvu yamagetsi ku katundu.Mphamvu zowonekera;Mphamvu yotulutsa mphamvu yamagetsi.

Kaya mphamvu yogwira ntchito imapangidwa zimadalira chikhalidwe cha katundu, ngati: pali inductors ndi capacitors mu katundu, mu zigawozi ayenera kudya mphamvu kusunga mphamvu, capacitors kusunga mphamvu yamagetsi, inductors kusunga maginito mphamvu, koma mphamvu izi. sizimadyedwa kwenikweni, zimangosungidwa mwanjira zosiyanasiyana, motero ndi gawo la mphamvu yotchedwa reactive power.

Kupanga mphamvu yogwira;M'dera la AC, katunduyo si katundu wangwiro wotsutsa, kotero katunduyo sangathe kupeza mphamvu zowonjezera mphamvu, koma payenera kukhala kuchepetsa mphamvu.Mphamvu yochepetsedwayi imagwiritsidwa ntchito posinthanitsa mphamvu zonyamula katundu kapena capacitive.Komabe, kuchepetsa gawo ili la mphamvu kwenikweni sikudyedwa, koma kusinthanitsa mphamvu kokha pakati pa magetsi ndi inductive katundu kapena capacitive katundu.Choncho, mphamvu yomwe imachepetsa gawo ili la kusinthanitsa mphamvu popanda kugwiritsa ntchito mphamvu yotchedwa reactive power.

Mphamvu yogwira ntchito ndi chinthu chapadera pakusinthana kachitidwe kamakono.Chofunika kwambiri cha mphamvu yogwira ntchito ndi mphamvu yomwe ilipo mumagetsi ndi maginito pazida zosiyanasiyana za mabwalo a AC, omwe ndi maziko oyendetsera zida zambiri zamagetsi.

Mtengo wa Noker ElectricSvg static var jeneretandi abwino kwambiri zotakasika mphamvu chipukuta misozi zida, akhoza anapereka kubweza dongosolo harmonic, zotakasika mphamvu, atatu gawo kusamvana, chimagwiritsidwa ntchito kachitidwe mphamvu zamagetsi.
