Chii chinonzi simba?

Kutanga, ndinokutendai nekuteerera kwenyu uye koshesai chinyorwa chino, uye tiri kutarisira kuverenga kwenyu nguva dzose. Muzvinyorwa zvinotevera, tichakupai ruzivo rwakawanda nezvemidziyo yemwenje, saka ndapota rambai makateerera.

Pakusarudza mwenje we LED, tichatanga tatarisa zvinhu zvine mativi akawanda zvakaita sesimba, lumen, tembiricha yemavara, giredhi remvura, kupisa, zvinhu nezvimwewo. Kana nekutarisa makatalogu ezvigadzirwa, kushanyira mawebhusaiti, kushandisa mainjini ekutsvaga eGoogle, kuona mavhidhiyo eYouTube kana kuburikidza nedzimwe nzira dzekuwana zvigadzirwa zvemhando yepamusoro zvinokurudzirwa. Chaizvoizvo, zvakakosha kuti vashandisi vataure nezvezvinhu izvi mukuita kwavo sarudzo. Asi, unoziva here kuti kukosha kwePF chii?

Chekutanga, kukosha kwePF (power factor) sesimba, kukosha kwePF kunomiririra cosine yemusiyano wechikamu pakati pemagetsi ekupinda nemagetsi ekupinda. Kukosha uku kunokanganisa zvakananga mashandiro ekushandiswa kwesimba remagetsi.

Izvi zvinotevera mamiriro maviri:

Kune mwenje we LED une PF shoma, simba remagetsi rinoshandurwa kuita simba rekupisa nedzimwe mhando dzesimba panguva yekushanda. Chikamu chesimba remagetsi hachigone kushandiswa zvinobudirira uye chinoraswa.

Imwe nyaya ndeyekushandisa mwenje we LED une PF yakawanda. Kana watanga, unoshandura simba remagetsi kuita simba rechiedza zvinobudirira, nokudaro uchichengetedza kushandiswa kwesimba uye uchideredza marara esimba.

Kukosha kwePF kunowanzoonekwa sechimwe chezvinhu zvakakosha pakuongorora mashandiro emwenje we LED. Saka, tinokurudzira zvakasimba kuti unyatsoteerera uye uenzanise kukosha kwePF kwemhando dzakasiyana dzemwenje nemodheru paunenge uchisarudza mwenje we LED. Nenzira yekuti, kukosha kwePF kwakakwira, kushanda nesimba kwakanyanya, uye kukanganisa nharaunda kuchaderedzwa zvinoenderana.

Kazhinji, kukosha kwePF chinhu chakakosha uye chine kukosha kwakakosha pakushandiswa kwesimba nemazvo. Saka, pakusarudza mwenje we LED, zvinokurudzirwa kufunga nezvezvinhu zvakaita sesimba, lumens, tembiricha yemavara, kushanda kwemvura, kugona kupisa, zvinhu, nezvimwewo, uye kutarisisa kukosha kwePF.
