Eqinisweni, amajeneretha edizili anemisebenzi eminingi. Ngakho-ke, kubaluleke kakhulu ukuvikela, ukuhlola nokugcina ijeneretha yedizili ngezikhathi ezithile. Ukugcinwa ngendlela efanele kuyisihluthulelo sokugcina ukusebenza okuvamile kwejeneretha yedizili.
Ukuze kugcinwe amajeneretha edizili ngendlela efanele, kubalulekile ukwazi amaphutha avamile angase awalimaze ukuze wazi ukuthi kudingeka nini ukulungiswa kabusha kwamajeneretha.
Kushiswe ngokweqile
Ukushisa ngokweqile kungenye yezifo ezivame kakhulu zokunakekelwa kwejeneretha. Ukushisa ngokweqile kumajeneretha kungabangelwa izimbangela ezihlukahlukene, okuhlanganisa ukugcwala kwejeneretha, isivinini esingaphezu kwesivinini, ukuwohloka kokufakwa kwama-winging kanye nokugcotshwa okwanele kukaphethiloli ophethe.
Lapho i-generator iqala ukushisa, i-alternator izophinde idlule, okunciphisa kakhulu ukusebenza kokufakwa kwama-windings. Uma kuzitshwa, ukushisa ngokweqile kuzolimaza kakhulu ezinye izingxenye zejeneretha, okungase kudinge ukulungiswa noma ukushintshwa.
Iphutha lamanje
I-fault current yinoma yiliphi igagasi eliphezulu ngokungenhloso ohlelweni lukagesi. Lawa maphutha angabangela izinkinga ezihlukahlukene ku-generator yakho. Ngokuvamile zibangelwa ama-circuits amancane ane-impedance ephansi.
Uma iphutha liyisekethi emfishane ekujikeni kwejeneretha, ijeneretha kufanele ihlolwe noma ilungiswe ngokushesha ngoba ukujikajika kungase kushise futhi konakale.
Motor drive
Ukusebenza kukagesi kwejeneretha kwenzeka lapho injini ingakwazi ukunikeza amandla anele ukuze i-generator ihlangabezane nezidingo zayo zomthwalo. Lapha, uhlelo lwejeneretha luphoqeleka ukuthi lunxephezele ukulahlekelwa ngokunikeza amandla asebenzayo enjinini, ngokuyisisekelo okwenza ijeneretha isebenze njengenjini kagesi.
I-motor drive ngeke ilimaze ngokushesha i-generator. Nokho, ukuyiziba kungabangela injini ukuba ishise kakhulu. Ngakho-ke, kuyadingeka ukuvikela injini, enganikezwa ngokushintsha umkhawulo noma umtshina wokushisa we-hood exhaust.
Ukulahlekelwa kazibuthe okusele
I-Residual magnetism yinani lamagnetization elishiywe ngokukhipha insimu yamagnetic yangaphandle kusekethe. Ngokuvamile kwenzeka kumajeneretha nezinjini. Ukulahlekelwa yizibuthe ezisele ku-generator kungabangela izinkinga ohlelweni.
Uma ijeneretha ingasetshenziswa isikhathi eside ngenxa yokuguga noma ukungaxhumeki kahle kwamajika e-excitation, ukulahlekelwa kazibuthe okusele kuzokwenzeka. Lapho le magnetism eyinsalela inyamalala, i-generator ngeke ikhiqize amandla ekuqaleni.
I-Undervoltage
Uma i-voltage ingakwazi ukuphakama ngemva kokuqaliswa kwe-generator, umshini ungase ubhekane nezinkinga ezinkulu. Ukungena kwamandla kagesi kwejeneretha kungase kwenzeke ngokungahleliwe ngenxa yezizathu ezihlukahlukene, okuhlanganisa ukuxutshwa kwefuse ezwa amandla kagesi kanye nokulimala kwesekhethi evusa amadlingozi.
Enye imbangela engenzeka yokungasebenzi kahle kwejeneretha ukuntuleka kokusetshenziswa. I-alternator yayo ishaja i-capacitor ngezinsalela zokusonta. Uma i-generator ingasetshenzisiwe isikhathi eside, i-capacitor ngeke ikhokhise futhi umthamo onganele uzokwenza ukuthi ukufundwa kwe-voltage ye-generator kube phansi kakhulu.
Ukuvikelwa nokugcinwa kwejeneretha kuyadingeka. Uma zingalungiswa ngokushesha, izinkinga ezinjengokushisa ngokweqile, i-fault current, motor drive, ukulahlekelwa kazibuthe okusele kanye nokungabi namandla kagesi kungase kubangele umonakalo ongenakulungiseka kujeneretha. Amajeneretha kadizili ayinsika ebalulekile yanoma yikuphi ukwehluleka ukufinyelela igridi kagesi evamile, kungakhathaliseki ukuthi ukugcina imishini yasesibhedlela esindisa ukuphila isebenza ngesikhathi sokunqamuka kukagesi noma ukusebenza ngaphandle njengokwakha nezolimo. Ngakho-ke, ukuphulwa kwe-generator circuit kungaba nemiphumela emibi kakhulu. Ngakho-ke, izimbangela ezivame kakhulu zamaphutha ejeneretha kufanele ziqondwe ukuze zibonakale futhi zilungiswe ngaphambi kokuba zidale umonakalo omkhulu kujeneretha.
