Unqume ukuthenga ijeneretha kadizili yesikhungo sakho njengomthombo wamandla osekelayo futhi waqala ukuthola izingcaphuno zalokhu.Ungaqiniseka kanjani ukuthi ukukhetha kwakho i-generator kuhambisana nezidingo zebhizinisi lakho?

IDATHA EYISISEKELO

Ukufunwa kwamandla kumele kufakwe esinyathelweni sokuqala solwazi oluthunyelwe yikhasimende, futhi kufanele kubalwe njengesamba semithwalo ezosebenza nejeneretha.Lapho kunqunywa isidingo samandla esiphezulu,imithwalo engase inyuke esikhathini esizayo kufanele icatshangelwe.Phakathi nalesi sigaba, ukukala kungacelwa kubakhiqizi.Nakuba isici samandla sihluka ngokuya nezici zemithwalo okufanele iphakelwe ijeneretha yedizili, amajeneretha kadizili akhiqizwa njengamandla wesici esingu-0.8 njengokujwayelekile.

I-Declared frequency-voltage iyahlukahluka kuye ngokuthi i-generator izothengwa kanjani, kanye nezwe esetshenziswa kulo.I-50-60 Hz, 400V-480V ivame ukubonakala lapho imikhiqizo yabakhiqizi bejeneretha ihlolwa.Ukubekwa phansi kwesistimu kufanele kucaciswe ngesikhathi sokuthenga, uma kusebenza.Uma isisekelo esikhethekile (TN, TT, IT ...) sizosetshenziswa ohlelweni lwakho, kufanele sicaciswe.

Izici zomthwalo kagesi oxhunyiwe zihlobene ngokuqondile nokusebenza kwe-generator.Kunconywa ukuthi kucaciswe izici ezilandelayo zomthwalo;

● Ulwazi lohlelo
● Layisha izici zamandla
● Isici samandla somthwalo
● Indlela yokuvula (uma kunenjini kagesi)
● Isici sokuhlukahluka somthwalo
● Inani lomthwalo wesikhashana
● Inani lomthwalo ongaqondile nezici
● Izici zenethiwekhi ezoxhunywa

Isimo esidingekayo sokuqina, imvamisa yesikhashana kanye nokuziphatha kwamandla kagesi kubaluleke kakhulu ukuze kuqinisekiswe ukuthi umthwalo enkundleni ungasebenza ngendlela enempilo ngaphandle kokulimala.

Uhlobo lwamafutha asetshenzisiwe kufanele lucaciswe uma kwenzeka kuba necala elikhethekile.Ukuze kusetshenziswe udizili:

● Ukuminyana
● I-Viscosity
● Inani lekhalori
● Inombolo ye-Cetane
● Okuqukethwe kwe-Vanadium, i-sodium, i-silica ne-aluminium oxide
● Ngamafutha anamandla;okuqukethwe kwesibabule kufanele kucaciswe.

NOMA YIYIPHI IFUTHA IKADIZISI ESETSHENZISWAYO KUMELE IVOBANE NE-TS EN 590 KANYE AMAZINGA E-ASTM D 975

Indlela yokuqala iyisici esibalulekile sokuvula ijeneretha yedizili.Amasistimu okuqala emishini, kagesi kanye ne-pneumatic yizinhlelo ezisetshenziswa kakhulu, nakuba zihluka ngokuya ngokusetshenziswa kwejeneretha.Uhlelo lokuqalisa lukagesi lusetshenziswa njengezinga elikhethwayo kumasethi wethu wokuphehla ugesi.Amasistimu okuqalisa umoya womoya asetshenziswa kakhulu ezinhlelweni ezikhethekile ezifana nezikhumulo zezindiza nezinkundla zikawoyela.

Ukupholisa nokungena komoya ekamelweni lapho ijeneretha ikhona kufanele kwabelwane ngayo nomkhiqizi.Kudingekile ukuthintana nabakhiqizi ukuze uthole imininingwane yokungena nokukhipha kanye nezidingo zejeneretha ekhethiwe.Isivinini sokusebenza ngu-1500 - 1800 rpm kuye ngenjongo nezwe lokusebenza.I-RPM esebenzayo kufanele ifakwe futhi igcinwe itholakala uma kwenzeka kucwaningwa.

Umthamo odingekayo wethangi likaphethiloli kufanele unqunywe isikhathi esiphezulu sokusebenza esidingekayo ngaphandle kokugcwalisa i-refuelingkanye nesikhathi esilinganisiwe sonyaka sokusebenza kwejeneretha.Izici zethangi likaphethiloli elizosetshenziswa (isibonelo: ngaphansi komhlaba / ngaphezulu komhlaba, udonga olulodwa / udonga oluphindwe kabili, ngaphakathi noma ngaphandle kwe-chassis ye-generator) kufanele zicaciswe ngokuvumelana nesimo somthwalo we-generator (100%, 75%, 50%, njll.).Amanani wehora (amahora angu-8, amahora angu-24, njll.) angacaciswa futhi ayatholakala kumkhiqizi uma ecelwa.

Isistimu ye-alternator excitation ithinta ngokuqondile isici somthwalo wesethi yakho yejeneretha kanye nesikhathi sayo sokuphendula emithwalweni eyahlukahlukene.Izinhlelo zokuvusa amadlingozi ezivame ukusetshenziswa abakhiqizi yilezi;i-auxiliary winding, i-PMG, i-Arep.

Isigaba sokulinganisa amandla sejeneretha esinye isici esithinta usayizi wejeneretha, obonakala enanini.Isigaba sokulinganisa amandla (njenge-prime, standby, continuous, DCP, LTP)

Indlela yokusebenza isho ukuvumelanisa okwenziwa ngesandla noma okuzenzakalelayo phakathi kwamanye amasethi amajeneretha noma ukusebenza kokuphakelwa kwamapayipi amakhulu namanye amajeneretha.Izisetshenziswa ezisizayo ezizosetshenziswa esimweni ngasinye ziyahlukahluka, futhi ziboniswa ngokuqondile emananini.

Ekucushweni kwesethi yejeneretha, lezi zinkinga ezingezansi kufanele zicaciswe:

● Ikhabethe, isidingo sesitsha
● Ukuthi isethi yejeneretha izolungiswa noma ihamba
● Ukuthi imvelo lapho ijeneretha izosebenza khona ivikelekile endaweni evulekile, indawo emboziwe noma ayivikelekile endaweni evulekile.

Izimo ze-ambient ziyisici esibalulekile okufanele sihlinzekwe ukuze ijeneretha kadizili ethengiwe inikeze amandla afunekayo.Izici ezilandelayo kufanele zinikezwe lapho ucela isipho.

● Izinga lokushisa le-ambient (Min and Max)
● Ukuphakama
● Umswakama

Uma kwenzeka kuba nothuli oluningi, isihlabathi, noma ukungcoliswa kwamakhemikhali endaweni lapho ijeneretha izosebenza khona, umenzi kufanele aziswe.

Amandla okukhipha amasethi ejeneretha anikezwa ngokuhambisana namazinga we-ISO 8528-1 ngokuya ngalezi zimo ezilandelayo.

● Ingqikithi yokucindezela kwe-barometric: 100 kPA
● Izinga lokushisa le-ambient: 25°C
● Umswakamo Ohlobene: 30%
