Yuav ua li cas xaiv lub cev muaj zog?
3-theem tsav. 110 kilowatts, rated 218A, ntsuas tam sim no (sijhawm) qhov no txhais tau li cas? Nws puas yog qhov piv ntawm pib pib mus rau tam sim no rated, qhov no yog 6.3 zaug, yuav ua li cas xaiv lub fuse? Puas yog nyob ntawm qhov pib tam sim no?
Hauv kev ua haujlwm ntev ntawm kev ua haujlwm, peb tau muab los sau qhia qee qhov kev paub hauv kev xaiv lub cav tawg. Cov kev xaiv siv feem ntau tau qhia raws li hauv qab no:
1. Thaum tsuas muaj lub cev muaj zog xwb, qhov ntsuas tam sim no ntawm lub fuse yuav tsum ntau dua lossis sib npaug li 1.5 mus rau 2.5 npaug ntawm qhov ntsuas tam sim no ntawm lub cev muaj zog.
Yog tias qhov peev xwm ntawm lub cev muaj zog me me, lossis thaum tsis muaj nra lossis teeb nra thaum pib, ntau yam tuaj yeem yog tus nqi me;
Rau lub cav fais fab loj los yog hnyav-pib, qhov ntau tuaj yeem yog tus nqi loj.
2. Thaum ntau lub cev muaj zog tswj los ntawm ib txoj kab lossis ib lub pob hloov chaw, tag nrho cov fuse xaiv txoj kev yog raws li hauv qab no: tag nrho cov fuse ntsuas tam sim no ≥ (1.5 ~ 2.5) × qhov siab tshaj plaws lub cev muaj zog nyob rau tam sim no + tus lej ntawm lwm lub cev muaj zog rated currents.
Nws yuav tsum raug sau tseg tias qhov ntsuas tam sim no ntawm tag nrho cov fuse tsis tuaj yeem dhau ntawm qhov tam sim no ntawm qhov hloov pauv ntawm kab.
Txwv tsis pub, thaum lub sijhawm hluav taws xob hauv lub sijhawm luv luv, lub hloov hluav taws xob tuaj yeem raug hlawv tawm.
3. Yog hais tias cov kab tsuas yog muab cov hwj huam rau lub teeb pom kev zoo, qhov ntsuas cov kab ntawm fuse yuav tsum yog me ntsis ntau dua los yog sib npaug ntawm qhov sib npaug ntawm qhov tam sim no ua haujlwm ntawm txhua lub teeb.
Vim tias lub fuse tiv thaiv kev nyab xeeb ntawm lub cev muaj zog thiab lwm yam khoom siv thaum muaj kev txhaum, nws yog qhov tseem ceeb uas yuav tsum xaiv lub fuse kom raug, txwv tsis pub nws yuav ncaj qha ua rau poob loj heev.
