Enyanisweni, iijenereyitha zedizili zinemisebenzi emininzi. Ngoko ke, kubaluleke kakhulu ukukhusela, ukuhlola nokugcina i-diesel generator ngamaxesha aqhelekileyo. Ukugcinwa okufanelekileyo kungundoqo wokugcina ukusebenza okuqhelekileyo kwejeneretha ye-diesel.
Ukuze kugcinwe i-diesel generator ngokuchanekileyo, kuyimfuneko ukwazi iimpazamo eziqhelekileyo ezinokuzonakalisa ukuze wazi xa kufuneka ukulungiswa kwee-generator.
Ubushushu obugqithisileyo
Ukushisa ngokugqithiseleyo yenye yezona zifo eziqhelekileyo zokuxilongwa kwejeneretha. Ukushisa ngokugqithiseleyo kwiijeneretha kunokubangelwa yizizathu ezahlukeneyo, kubandakanywa ukugqithiswa kwejeneretha, i-overspeed, i-winding insulation breakdown kunye nokungonelanga kwe-lubrication ye-fuel bearing.
Xa i-generator iqala ukufudumala, i-alternator iya kuphinda igqithise, eyanciphisa kakhulu ukusebenza kwe-insulation of windings. Ukuba kungahoywa, ukufudumala kuya kulimaza ngakumbi ezinye iindawo zejeneretha, ezinokufuna ukulungiswa okanye ukutshintshwa.
Impazamo yangoku
Impazamo yombane yiyo nayiphi na imisinga ephezulu ngokungeyonjongo kwisixokelelwano sombane. Ezi mpazamo zinokubangela iingxaki ezahlukeneyo kwijenereyitha yakho. Ngokuqhelekileyo zibangelwa yimijikelezo emfutshane ene-impedance ephantsi.
Ukuba impazamo yisekethe emfutshane kwijenereyitha yokujija, ijenereyitha kufuneka ihlolwe okanye ilungiswe ngokukhawuleza kuba i-winding ingaba shushu kwaye yonakaliswe.
Ukuqhuba imoto
Ukusebenza kombane wejeneretha kwenzeka xa injini ingakwazi ukunika amandla aneleyo ukuba i-generator ihlangabezane neemfuno zayo zomthwalo. Apha, inkqubo ye-generator inyanzelekile ukuba ihlawule ilahleko ngokunika amandla asebenzayo kwi-injini, ngokukodwa ukwenza ukuba i-generator isebenze njengemoto yombane.
I-motor drive ayiyi kulimaza ngokukhawuleza i-generator. Nangona kunjalo, ukungayinaki kunokubangela ukuba injini ishushu. Ngoko ke, kuyimfuneko ukukhusela i-injini, enokuthi ibonelelwe ngokutshintshela umda okanye umtshini wokushisa we-hood exhaust.
Ilahleko eseleyo yamagnetic
Imagnethi eshiyekileyo sisixa semagneti esishiywe ngokususa umhlaba wemagnethi wangaphandle kwisekethe. Ngokuqhelekileyo kwenzeka kwiijenereyitha kunye neenjini. Ukulahlekelwa ngumazibuthe oseleyo kwijeneretha kunokubangela iingxaki kwinkqubo.
Xa ijeneretha ingasetyenziswanga ixesha elide ngenxa yokuguga okanye ukungaxhunywanga kwe-excitation winding, ilahleko yemagnethi eseleyo iya kwenzeka. Xa le magnetism ishiyekileyo inyamalala, ijenereyitha ayiyi kuvelisa nawaphi na amandla ekuqaleni.
Ukungabikho kwamandla
Ukuba i-voltage ayikwazi ukuphakama emva kokuba i-generator iqalisiwe, umatshini unokujongana neengxaki ezinzulu. I-Undervoltage ye-generator inokuthi yenzeke ngokungaqhelekanga ngenxa yezizathu ezahlukeneyo, kubandakanywa ukuxutywa kwe-fuse ye-voltage-sensing fuse kunye nomonakalo kwisekethe yokuvuselela.
Enye into enokubangela ukungabikho kwamandla ombane kwijeneretha kukungabikho kokusetyenziswa. I-alternator yayo ihlawulisa i-capacitor kunye neentsalela zomoya. Ukuba i-generator ingasetyenziswanga ixesha elide, i-capacitor ayiyi kuhlawulisa kwaye umthamo ongafanelekanga uya kubangela ukuba ukufundwa kwe-voltage ye-generator kuphantsi kakhulu.
Ukukhuselwa kunye nokugcinwa kwejeneretha kuyimfuneko. Ukuba ayilungiswanga ngokukhawuleza, iingxaki ezinjengokushisa okugqithisileyo, i-fault current, i-motor drive, intsalela yelahleko yemagnethi kunye nokungabikho kwamandla ombane kunokubangela umonakalo ongenakulungiseka kwijenereyitha. Iijenereyitha ze-diesel ziyintsika ebalulekileyo yalo naluphi na ukusilela ukufikelela kwigridi yamandla eqhelekileyo, nokuba kukugcina oomatshini abasindisa ubomi besibhedlele besebenza ngexesha lokuphela kombane okanye ukusebenza ngaphandle njengokwakha kunye nezolimo. Ngoko ke, ukuphulwa kweesekethe zejeneretha kunokuba nemiphumo emibi. Ngoko ke, ezona zizathu zixhaphakileyo zeziphene zejenereyitha zifanele ziqondwe ukuze zichongwe zize zilungiswe ngaphambi kokuba zenze umonakalo omkhulu kwijenereyitha.
