Sankhani waya molingana ndi mtengo wololeka wa mphamvu yonyamulira ya waya

Chigawo chodutsa waya cha mawaya amkati chiyenera kusankhidwa molingana ndi momwe waya wovomerezeka akunyamulira, kutayika kwa magetsi ovomerezeka a chingwe, ndi mphamvu yamakina a waya.Nthawi zambiri, waya wonyamulira pamwamba amasankhidwa malinga ndi mphamvu yonyamulira yomwe ikuloledwa, ndiyeno kutsimikizira kumachitika molingana ndi zina.Ngati gawo la mtanda silikukwaniritsa zofunikira zamtundu wina wa calibration, woyendetsa ayenera kusankhidwa molingana ndi gawo lovomerezeka lovomerezeka lomwe silingakwaniritse chikhalidwecho.

Mawaya ovomerezeka ampacity: Kukula kovomerezeka kwa waya kumatchedwanso kutetezedwa kotetezedwa kapena mtengo wotetezedwa wa waya.Kutentha kwakukulu kovomerezeka kwa waya wamba ndi 65 ° C.Ngati kutentha kupitilira kutentha uku, chingwe chotchingira cha waya chimakalamba mwachangu, chimawonongeka ndikuwonongeka, ndipo chikhoza kuyambitsa moto.Zomwe zimatchedwa mphamvu zololeka za waya ndizofunika kwambiri zomwe zingathe kuperekedwa kwa nthawi yaitali pamene kutentha kwa ntchito sikudutsa 65 ° C.

Popeza kutentha kwa ntchito kwa waya sikungokhudzana ndi zomwe zikuchitika panopa, komanso kukhudzana ndi kutentha kwa kutentha kwa waya ndi kutentha kozungulira, mphamvu yololeka yonyamula waya simtengo wokhazikika.Pamene waya womwewo utenga njira zoyakira zosiyana (njira zoyakira zosiyana, kutentha kwake kumakhalanso kosiyana) kapena kutentha kosiyanasiyana, mphamvu yake yololeka yomwe ikuloledwa ndi yosiyana.Onani bukhu laukadaulo lamagetsi la mphamvu yovomerezeka yonyamulira mawaya pogwiritsa ntchito njira zoyalira zosiyanasiyana.

Pakalipano pamzere wa mzerewu ukhoza kuwerengedwa motsatira ndondomeko iyi:

Gawo limodzi lodziletsa lokhazikika: I=P/U

Kuzungulira gawo limodzi ndi inductance: I=P/Ucosφ

Gawo la magawo atatu koyera kukana: I=P/√3UL

Magawo atatu okhala ndi inductance: I=P/√3ULcosφ

Tanthauzo la magawo omwe ali pamwambawa ndi awa:

P: ndi mphamvu ya katundu, mu watts (W);

UL: ndi voteji ya magawo atatu amagetsi, mu volts (V);

cosφ: ndiye chinthu champhamvu.

Posankha molingana ndi mphamvu yonyamulira yomwe ikuloledwa pakali pano ya waya, mfundo yaikulu ndi yakuti mphamvu yovomerezeka yomwe ilipo panopa siicheperapo kusiyana ndi kuwerengetsera komweku kwa mzere wa mzere.
