1. Q: Emva kokuba umqhubi ethatha isethi yejenereyitha yedizili, Ngawaphi amanqaku amathathu okuqinisekisa?
A: 1) Qinisekisa awona mandla aluncedo eyunithi. Emva koko misela amandla ezoqoqosho, kunye namandla okulinda. Indlela yokuqinisekisa awona mandla aluncedo eyunithi yile: amandla alinganisiweyo iiyure ezili-12injini yediziliiphindaphindwe ngo-0.9 ukufumana idatha (kw), ukuba amandla alinganisiweyo e-generator angaphantsi okanye alingana nedatha, amandla alinganisiweyo we-generator anqunywe njengamandla okwenene aluncedo kwiyunithi, ukuba amandla alinganisiweyo i-generator inkulu kunedatha, idatha kufuneka isetyenziswe njengamandla okwenene aluncedo kwiyunithi; 2) Qinisekisa ukuba yeyiphi imisebenzi yokuzikhusela iyunithi enayo; 3) Qinisekisa ukuba i-wiring yamandla yeyunithi ifanelekile, ingaba i-grounding yokukhusela inokwethenjelwa, kwaye ingaba umthwalo wesigaba sesithathu ulungelelaniswe ngokusisiseko.
2. Umbuzo: I-elevator yokuqalisa i-motor yi-22KW, kwaye isethi enkulu yejeneretha kufuneka ixhotyiswe?
A: 22 * 7 = 154KW (i-elevator yimodeli yokuqala yomthwalo othe ngqo, kwaye isantya sokuqala sangoku ngokuqhelekileyo siphindaphinda ama-7 angoku alinganisiweyo ukuqinisekisa ukuba i-elevator ihamba ngesantya esingaguqukiyo). (Oko kukuthi, ubuncinci be-154KWiseti yejenereyithakufuneka ixhotyiswe)
3. Q: Indlela yokubala awona mandla afanelekileyo okusetyenziswa (amandla ezoqoqosho) kwiseti yejeneretha?
A: P optimum = 3/4 * P rating (okt 0.75 amaxesha alinganiselwe amandla).
4. Q: Ingaba nkulu kangakanani urhulumente uchaza ukuba amandla e-injini ye-generator jikelele iseti kuneamandla ejenereyitha?
A: 10℅.
5. Q: Amanye amandla e-injini yejenereyitha abonakaliswa ngamandla ehashe, ukuguqulwa njani phakathi kwamandla ehashe kunye neeyunithi zamazwe ngamazwe zeekilowatts?
A: 1 amandla ehashe = 0.735 kW, 1 kW = 1.36 HP.
6. Q: Indlela yokubala i-current yeijenereyitha enezigaba ezithathu?
A: I = P / 3 Ucos phi ()), okwangoku = amandla (watts) / 3 * 400 () (v) * 0.8) UJane ubale ifomula yile: (I) (A) = amandla alinganisiweyo (KW) * 1.8
7. Q: Ubudlelwane phakathi kwamandla abonakalayo, amandla asebenzayo, amandla alinganisiweyo, amandla aphezulu kunye namandla ezoqoqosho?
A: I-1) Iyunithi yamandla abonakalayo yi-KVA, esetyenziselwa ukubonisa amandla e-transformers kunye ne-UPS e-China; 2) Amandla asebenzayo ngamaxesha angama-0.8 wamandla abonakalayo, iyunithi yi-KW, esetyenziswaizixhobo zokuvelisa amandlakunye nezixhobo zombane eTshayina; I-3) Amandla alinganisiweyo wesethi ye-diesel generator ibhekisela kumandla anokuthi aqhube ngokuqhubekayo kwiiyure ze-12; I-4) Amandla aphezulu ngamaxesha e-1.1 amandla alinganisiweyo, kodwa kuphela iyure ye-1 ivunyelwe kwiiyure ze-12; I-5) Amandla ezoqoqosho ngamaxesha e-0.75 yamandla alinganisiweyo, amandla okuvelisa isethi ye-diesel generator enokuthi iqhube ixesha elide ngaphandle kwezithintelo zexesha. Xa ubaleka kula mandla, amafutha yeyona nto igcinwe kwaye izinga lokungaphumeleli lelona lisezantsi.
8. Umbuzo: Kutheni ungavumeli iijenereyitha ze-diesel ukuba zisebenze ixesha elide ngaphantsi kwe-50% yamandla alinganisiweyo?
A: Ukonyuka kokusetyenziswa kwe-oyile, i-injini ye-diesel ilula kwikhabhoni, yonyusa izinga lokungaphumeleli, mfutshane umjikelo wokulungisa.
9. Q: Awona mandla emveliso yeijenereyithangexesha lokusebenza kuxhomekeke kwimitha yamandla okanye i-ammeter?
A: I-ammeter isetyenziselwa ireferensi kuphela.
