16. Maitiro ekuverenga iyo yazvino yetatu-chikamu jenareta?
Mhinduro: I = P / (√3 Ucos φ) ndiko kuti, ikozvino = simba (watts) / (√3 * 400 (volt) * 0.8).
Fomula yakareruka ndeiyi: Ini (A) = yuniti yakayerwa simba (KW) * 1.8
17. Ndeupi hukama huri pakati pesimba rinooneka, simba rinoshanda, simba rakatemwa, simba rakanyanya, uye simba rehupfumi?
Mhinduro: 1) Chidimbu chesimba rinooneka KVA, iyo inoshandiswa kuratidza kugona kwevashanduri neUPS munyika medu.
2) Simba rinoshanda iri 0.8 nguva inooneka simba, muKW, iyo inoshandiswa mumagetsi ekugadzira michina nemidziyo yemagetsi munyika yangu.
3) Iyo yakatemwa simba redhiziri seti jenareta rinoreva iro simba rinogona kushanda richienderera kwemaawa gumi nemaviri.
4) Simba rakakura i1.1 nguva iro rakatarwa simba, asi chete 1 awa inobvumidzwa mukati meawa gumi nemaviri.
5) Simba rehupfumi ndere 0.75 zvakapetwa iro rakatemwa simba, rinova iro simba rekuburitsa iro seti yedhiziri inogadzirirwa inogona kumhanya kwenguva yakareba pasina kukamurwa kwenguva. Kana uchimhanya pasimba iri, mafuta ndiwo mashoma uye mwero wekutadza ndiwo wakaderera.
18. Nei zvisingatenderwe kuti dhiziri jenareta seti kuti imhanye kwenguva yakareba kana simba riri pasi pe50% yesimba rakatemwa.
Mhinduro: Kuwedzera kwekushandisa kwemafuta kunoita kuti injini dzedhiziri dzikwanise kugadzirwa nekabhoni, izvo zvinowedzera mwero wekutadza uye kupfupisa nguva yekugadzirisa.
19. Iyo chaiyo yekubuditsa simba rejenareta panguva yekushanda yakavakirwa pawattmeter kana ammeter?
Mhinduro: Ammeter ichakunda, uye iyo mita yemagetsi ndeyekureva chete.
20. Iyo frequency uye voltage yejenareta seti ese ari maviri asina kugadzikana. Ndiro dambudziko neinjini kana jenareta?
Mhinduro: Inorara muinjini.
