1. Q: Mushure mekunge mushandisi atora seti yedhiziri, Ndeipi pamapoinzi matatu ekutanga kuratidza?

A: 1) Simbisa iyo chaiyo inobatsira simba reyuniti. Zvadaro sarudza simba rehupfumi, uye simba rekumira. Iyo nzira yekuona iyo chaiyo inobatsira simba reyuniti iyi: iyo 12-awa yakayerwa simba reiyoinjini yedhiziriinowedzerwa ne 0.9 kuti iwane data (kw), kana iyo yakatemerwa simba rejenareta iri shoma kana yakaenzana nedata, iro rakatemerwa simba rejenareta rinotarirwa sesimba rechokwadi rinobatsira rechikamu, kana iro rakatemerwa simba rejenareta. jenareta yakakura kudarika data, iyo data inofanira kushandiswa seyo chaiyo inobatsira simba rechikwata; 2) Tarisa uone kuti ndeipi basa rekuzvidzivirira iro iyo unit ine; 3) Simbisa kana iyo wiring yemagetsi yeyuniti inokodzera, ingave iyo yekudzivirira ivhu yakavimbika, uye kana matatu-chikamu mutoro wakanyatsoenderana.

2. Q: Iyo elevator yekutanga mota ndeye 22KW, uye yakakura sei seti yejenareta inofanira kunge yakashongedzerwa?

A: 22*7=154KW (rifiti inotakura yakananga modhi yekutangisa, uye pakarepo inotangira ikozvino kazhinji kanomwe pane yakayerwa ikozvino kuti ive nechokwadi chekuti lifti inofamba ichimhanya nguva dzose). (Kureva, ingangoita 154KWgenerator setinofanira kunge yakashongedzwa)

3. Q: Nzira yekuverenga sei rakakwana rekushandisa simba (simba rehupfumi) rejenareta seti?

A: P optimum = 3/4 * P chiyero (kureva 0.75 times rated power).

4. Q: Zvakakura sei nyika inotaura kuti simba rejini rejenareta rakaiswa panejenareta simba?

A: 10℅.

5. Q: Rimwe simba rejini yejenareta rinoratidzwa nebhiza, sei kushandura pakati pebhiza nezvikamu zvepasi rose zve kilowatts?

A: 1 bhiza =0.735 kW, 1 kW =1.36 HP.

6. Q: Nzira yekuverenga sei ikozvino yematatu-phase jenareta?

A: Ini = P / 3 Ucos phi ()), ikozvino = simba (watts) / 3 * 400 () (v) * 0.8) Jane kuverenga formula ndeye: (I) (A) = yakayerwa simba (KW) * 1.8

7. Q: Ukama huri pakati pesimba rinoratidzika, simba rinoshanda, simba rakarongwa, simba guru uye simba rehupfumi?

A: 1) Chikamu chesimba rinoratidzika iKVA, iyo inoshandiswa kuratidza kukwanisa kwevashanduri uye UPS muChina; 2) Simba rinoshanda 0.8 nguva dzesimba rinoratidzika, iyo unit ndeye KW, iyo inoshandiswa mumidziyo yekugadzira magetsiuye midziyo yemagetsi muChina; 3) Simba rakarongerwa rejenareta redhiziri rinoreva simba rinogona kuenderera mberi kwemaawa gumi nemaviri; 4) Simba guru ndiro 1.1 nguva yesimba rakarongwa, asi awa imwe chete inobvumirwa mukati maawa gumi nemaviri; 5) Simba rehupfumi ndeye 0.75 nguva yesimba rakarongwa, iro ndiro simba rinobuda rejenareta redhiziri rinogona kushanda kwenguva yakareba pasina kurambidzwa kwenguva. Paunenge uchimhanya pasimba iri, mafuta ndiwo anonyanya kuchengetwa uye chiyero chekukundikana ndicho chakaderera.

8. Mubvunzo: Wadii kubvumira majenereta edhiziri kuti ashande kwenguva yakareba pane isingasviki 50% yesimba rakarongwa?

A: Kuwedzera kushandiswa kwemafuta, injini yedhiziri iri nyore kuita kabhoni, wedzera mwero wekutadza, kupfupisa kutenderera kutenderera.

9. Q: Iyo chaiyo yekuburitsa simba rejenaretapanguva yekushanda zvinoenderana nemamita emagetsi kana ammeter?

A: Iyo ammeter inoshandiswa kunongedzera chete.
