Ixazululwa Kanjani Inkinga Yesekethe Emfishane Yesethi Ye-Volvo Diesel Generator

Amasethi ejeneretha edizili yakwaVolvo awavamile ukuba nenkinga yamasekethe amafushane ngesikhathi sokusetshenziswa.Yiziphi izizathu eziyinhloko nokuthi zingaxazululwa kanjani?Umkhiqizi wejeneretha engu-100KW wabelana nawe.

1. Izici zesifunda esifushane ngokuzumayo.

Esimeni se-short-circuit enesimo esiqinile, ngenxa yokusabela okukhulu okuvumelanayo, amandla esekethe yesimo esiqinile awasikhulu, futhi esimweni se-short-circuit, ngenxa yokuthi ukusabela okwedlula ngokweqile okukhawulela yamanje incane futhi iqukethe ingxenye yamanje eqondile, i-current short-circuit current inkulu , Inani layo eliphakeme lingafinyelela izikhathi ezingaphezu kweziyishumi zamanje ezilinganiselwe.

Ngokuvela kwalokhu kungena kwe-inrush current, ama-windings e-motor azobhekana namandla amakhulu we-electromagnetic, angase akhubaze ama-windings futhi alimaze ukufakwa kwama-windings.

Enqubweni yesifunda esifushane esingazelelwe, i-motor ingaphansi kwe-torque eqinile ye-short-circuit, futhi kungenzeka ukudlidliza.

I-stator ne-rotor windings ye-motor ine-overvoltage.

2. Izici zezimo ezibonakalayo ngaphakathi kwe ijeneretha ngesikhathi sokujikeleza okufushane okungazelelwe.

Esimeni se-short-circuit yesimo esiqinile, i-armature current ayiguquki, futhi amandla ahambisanayo e-armature magnetomotive iyi-amplitude ejikelezayo yenkundla kazibuthe ezungezisayo ngesivinini esivumelanayo, ngakho-ke ngeke ibangele amandla e-electromotive kumajika e-rotor futhi ikhiqize. okwamanje.Kusukela ebuhlotsheni bamanje Buka, ilingana nesimo esivulekile se-transformer.

Lapho kwenzeka isifunda esifushane esingazelelwe, ubukhulu be-armature yamanje buyashintsha, futhi i-armature magnetic field amplitude ehambisanayo iyashintsha.Ngakho-ke, i-transformer isebenza phakathi kwe-stator ne-rotor, eyenza amandla kagesi kanye namanje ku-rotor windings, bese ithinta i-stator windings.Ngokombono wobudlelwane be-electromagnetic, ukuguqulwa kwamandla aphakathi kuyalingana nesimo se-short-circuit esisheshayo se-transformer.

Phakathi nenqubo evamile yokuphehla amandla esethi ye-Volvo diesel generator, izinto zikagesi zashintsha ngokuzumayo futhi kwavela i-fireball enkulu, okwabangela ukuba i-voltage ye-generator ne-frequency inyamalale, futhi injini ye-diesel yaqalwa futhi ngesivinini esilinganisiwe, kanye nejeneretha. ayikwazanga ukusungula i-voltage.

Ukuhlaziywa kokwehluleka:

Ngemva kokuba u-opharetha noma umuntu olungisayo ethole iphutha elinjalo, kufanele bahlole i-fuse evusa amadlingozi kuqala, bese behlola i-stator ye-generator, i-exciter kanye nezingxenye zokulawula i-generator.Kuphela ngemva kokuqinisekisa ukuthi azikho izingxenye ezilimele lapho injini diesel ingaqalwa.Uma i-generator ingakhiqizi ugesi, i-voltage esele yamagnetization ye-exciter kufanele ihlolwe.

Isizathu samaphutha:

(1) Kukhona isifunda esivulekile noma isifunda esifushane ngaphakathi kwe-exciter.

(2) I-fuse yokuvusa ivulekile.

(3) Ukuphuka kweshubhu okwesibili.

(4) Kukhona isekethe emfushane noma isekethe evulekile ngaphakathi kwe-reactor.

(5) Uzibuthe osele we-exciter uyanyamalala.

Indlela yokuxazulula inkinga:

Ingxenye yokulawula yale sethi yejeneretha kadizili isebenzisa ukulawulwa kwamandla kagesi okuzenzakalelayo kwesigaba, ngakho-ke lapho uxazulula inkinga yalolu hlobo lwephutha, kubalulekile ukuqonda umgomo wesigaba se-compound excitation ukulawulwa kwamandla kagesi okuzenzakalelayo kanye nokwakheka kwengxenye kanye nendima yesistimu ngayinye encane, bese ulandela izinyathelo ukusuka kokulula kuye kumgomo wokuhlola okuyinkimbinkimbi.

(1) Hlola i-fuse futhi uthole ukuthi i-fuse ishaywe umoya.Qaphela ukuthi izingxenye ezisebhokisini lokulawula ziyashiswa yini.Ngesikhathi sokuhlolwa, kutholakala ukuthi amashubhu amabili akhawulelwe manje ashisiwe.

(2) Sebenzisa i-multimeter ukukala ama-diode okulungisa angu-6, futhi akukho okungavamile okutholakele emiphumeleni yokuhlolwa.

(3) Sebenzisa i-multimeter ukuze uhlole ukumelana kwe-exciter, futhi ukumelana okulinganiselwe kungu-3.5Ω, okubonisa ukuthi ukuvuthwa kwangaphakathi kwe-exciter konakalisiwe (ukumelana okuvamile cishe ku-0.5Ω).

(4) Ngemva kokufaka ishubhu lesibili lokunciphisa lamanje kanye ne-fuse, lapho injini ye-diesel iqaliswa ngesivinini esilinganisiwe, i-generator ngeke ikhiqize ugesi.

Lokhu kukhombisa ukuthi iphutha lingase libe ukuthi i-voltage ye-remanence yangaphakathi ye-exciter iphansi kakhulu (ngenqubo yokukhiqiza amandla ajwayelekile, imishini kagesi ibonakala ngokuzumayo i-short-circuits kanye ne-fireball enkulu, okuzokwenza ukuthi i-voltage remanence yangaphakathi ye-exciter ivele. ukunyamalala.

(5) Ngemva kokwenza uzibuthe i-exciter ngebhethri, qala injini ye-diesel ngesivinini esilinganiselwe, futhi i-generator izoqala ukukhiqiza ugesi futhi ihlangabezane nezidingo ezicacisiwe.
