Uyisombulula njani iNgxaki yeSekethe emifutshane yeSeti ye-Volvo Diesel Generator

Iiseti zejenereyitha yedizili yakwaVolvo azifane zibe nengxaki yeesekethe ezimfutshane ngexesha lokusetyenziswa.Ziziphi izizathu eziphambili kunye nendlela yokusombulula?100KW umenzi wejenereyitha wabelana nawe.

1. Iimpawu zesiphaluka esifutshane ngokukhawuleza.

Kwimeko yemo yesiphaluka esizinzileyo, ngenxa yokusabela okukhulu kwe-synchronous, i-short-state ye-short-state current ayinkulu, kwaye kwimeko ye-short-circuit, ngenxa yokuba i-super-transient reactance ithintela yangoku incinci kwaye iqulethe icandelo langoku ngokuthe ngqo, ngokukhawuleza i-short-circuit current inkulu , Ixabiso layo eliphakamileyo linokufikelela ngaphezu kweshumi langoku elilinganisiweyo.

Ngokuvela kolu tshintsho lwangoku, i-winding ye-motor iya kuba phantsi kwempembelelo enkulu ye-electromagnetic force, enokuthi iguqule i-windings kwaye yonakalise ukugquma kwee-windings.

Kwinkqubo yesiphaluka esifutshane ngokukhawuleza, i-motor ifakwe kwi-torque eyomeleleyo ye-short-circuit, kwaye i-vibration ingenzeka.

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

2. Iimpawu zezinto ezibonakalayo ngaphakathi ijenereyitha ngexesha lesiphaluka esifutshane ngesiquphe.

Kwimeko ye-short-state short-circuit, i-armature current ihleli, kwaye i-armature magnetomotive force ehambelanayo yi-amplitude engaguqukiyo ejikeleza intsimi yamagnetic ejikelezayo ngesantya esihambelanayo, ngoko ayiyi kubangela amandla e-electromotive kwi-rotor windings kunye nokuvelisa. yangoku.Ukususela kubudlelwane obukhoyo Jonga, ilingana nemeko evulekileyo ye-transformer.

Xa kwenzeka isiphaluka esifutshane ngokukhawuleza, ubukhulu be-armature yangoku buguqukayo, kunye ne-armature magnetic field amplitude ehambelanayo.Ngoko ke, i-transformer isebenza phakathi kwe-stator kunye ne-rotor, eyenza amandla ombane kunye nokukhoyo kwi-rotor windings, kwaye emva koko ichaphazela i-stator windings.Ukususela kumbono wobudlelwane be-electromagnetic, utshintsho lwangoku oluphakathi lulingana nemeko ye-short-circuit ngokukhawuleza ye-transformer.

Ngexesha lenkqubo eqhelekileyo yokuvelisa amandla e-Volvo diesel generator set, izixhobo zombane ngokukhawuleza zajikeleza kwaye kwavela i-fireball enkulu, eyabangela ukuba i-voltage ye-generator kunye ne-frequency yanyamalale, kwaye injini ye-diesel yaqaliswa kwisantya esilinganisiweyo kwakhona, kunye nejeneretha. ayikwazanga kuseka amandla ombane.

Uhlalutyo lokusilela:

Emva kokuba umqhubi okanye umntu wolondolozo efumene isiphoso esinjalo, kufuneka bajonge i-fuse yokuvuselela kuqala, baze bajonge i-stator ye-generator, i-exciter kunye neendawo zokulawula i-generator.Kuphela emva kokuqinisekisa ukuba akukho ndawo zonakeleyo apho injini yedizili ingaqaliswa.Ukuba ijenereyitha ayivezi mbane, intsalela yombane wemagnetization ye-exciter kufuneka ijongwe.

Unobangela weempazamo:

(1) Kukho isiphaluka esivulekileyo okanye isiphaluka esifutshane ngaphakathi kwe-exciter.

(2) I-fuse yokuvuselela ivuliwe.

(3) Ukuqhekeka kwetyhubhu yesibini.

(4) Kukho isiphaluka esifutshane okanye isiphaluka esivulekileyo ngaphakathi kwe-reactor.

(5) Uzibuthe oshiyekileyo we-exciter uyanyamalala.

Indlela yokulungisa ingxaki:

Inxalenye yolawulo yale seti yejenereyitha yedizili ithatha i-excitation ye-compound yesigaba solawulo lombane oluzenzekelayo, ke xa ulungisa ingxaki yolu hlobo lwempazamo, kuyafuneka ukuba uqonde umgaqo wesigaba sokuvuselela amandla ombane ozenzekelayo kunye nokwakheka kwecandelo kunye nendima yenkqubo ephantsi nganye, kwaye emva koko ulandele amanyathelo ukusuka kokulula ukuya kumgaqo wokuhlola onzima.

(1) Khangela i-fuse uze ufumanise ukuba ifuse ivuthelwe.Jonga ukuba ingaba iindawo ezikwibhokisi yolawulo zitshisiwe na.Ngethuba lokuhlolwa, kufunyenwe ukuba iibhubhu ezimbini ezinqamlekileyo zitshiswa ngaphandle.

(2) Sebenzisa i-multimeter ukulinganisa i-6 rectifier diode, kwaye akukho ntlupheko efunyenweyo kwiziphumo zovavanyo.

(3) Sebenzisa i-multimeter ukuvavanya ukuchasana kwe-exciter, kwaye ukuchasana okulinganisiweyo yi-3.5Ω, ebonisa ukuba ukuvuthwa kwangaphakathi kwe-exciter konakaliswe (ukuchasana okuqhelekileyo malunga ne-0.5Ω).

(4) Emva kokutshintsha ityhubhu yesibini yangoku yokunciphisa kunye ne-fuse, xa injini ye-diesel iqaliswa kwisantya esilinganisiweyo, i-generator ayiyi kuvelisa umbane.

Oku kubonisa ukuba impazamo inokuba kukuba i-voltage ye-remanence yangaphakathi ye-exciter iphantsi kakhulu (kwinkqubo yokuvelisa amandla aqhelekileyo, izixhobo zombane ngokukhawuleza zifutshane kunye ne-fireball enkulu, eya kubangela ukuba i-voltage remanence yangaphakathi ye-exciter ibonakale. ukunyamalala.

(5) Emva kokwenza imagnethi i-exciter ngebhetri, qalisa i-injini ye-diesel kwisantya esilinganiselwe, kwaye i-generator iya kuqalisa ukuvelisa umbane kwaye ihlangabezane neemfuno ezichaziweyo.
