Isigaba sesi-3 sesi-4 Isihluzi saMandla esiSebenzayo 480v 75a 150a Iphaneli ye-Apf

Inkcazelo emfutshane:

Imithwalo eyongezelelekileyo ayinamda, ingenisa i-harmonics kwigridi yamandla kwaye ngaloo ndlela iwonakalise kakhulu umgangatho wamandla.Isihluzi esisebenzayo se-harmonic i-3p4w yimveliso efanelekileyo inciphisa ngempumelelo ii-harmonics ezingafunekiyo.

Imithwalo engahambelaniyo, ngokungafaniyo nemithwalo yomgca, iye yaxhaphaka kakhulu: abaguquli befrikhwensi kwiinkqubo zokuqhuba, amanani amakhulu ombane we-switch-mode esetyenziswa kwi-IT kunye nezixhobo zonxibelelwano, kwaye ngakumbi nangakumbi kwi-electronics yasekhaya.Nobuchwephesha bokukhanyisa busebenzisa ubukhulu becala izixhobo zombane ezingezizo emgceni.Imithwalo engahambelaniyo iba ngakumbi nangakumbi kwizityalo zemizi-mveliso, izakhiwo zeofisi, amaziko edatha okanye kumakhaya abucala.

Umsebenzisi unokuseta iiparamitha ukwenzela ukuba izihluzi ezisebenzayo zihluze ngaxeshanye ii-harmonics, zihlawule ngamandla amandla asebenzayo, zibuyisele ukungalingani kwezigaba ezithathu, kunye nokubuyisela ukuhla kwamandla ombane, njl.
