Indlela Yokukhipha Uzibuthe kanye Nomsebenzi ka-900kw Diesel Generator

900kw generator diesel, njengoba isethi yejeneretha yamandla aphezulu , inamandla aphelele namandla aqinile.Ngesikhathi esifanayo, njengesethi ye-generator diesel, inezici zokusebenza okulula nokugcinwa okulula.Kungakanani okwaziyo mayelana nendlela yokuqeda uzibuthe kanye nokusebenza kuka-900kw generator diesel?

Ijeneretha kadizili enamandla angu-900kw iphenduka incithakalo.

Kusetshenziswa isimo sokusebenza se-inverter sebhuloho elilawula ngokugcwele lezigaba ezintathu, i-engeli yokulawula iyashintshwa isuke esimweni sokusebenza sokulungisa esingaphansi kuka-90° iye ku-engeli efanele enkulu kuno-90°.Ngalesi sikhathi, amandla e-excitation ayashintshwa futhi asetshenziswe ekuphepheni kwe-excitation ngendlela ye-EMF engemuva., Inqubo ye-de-excitation lapho i-rotor yamanje ibola ngokushesha ibe yiziro ibizwa ngokuthi i-inverter de-excitation.Le ndlela yokususa isasasa ibuyisela ngokushesha isitoreji samandla erotha endaweni yamandla eseceleni ye-AC yebhuloho elilawula ngokugcwele lezigaba ezintathu, futhi ayidingi izinto eziphikisa ukukhishwa noma amagridi okucisha ama-arc.Kuyindlela elula nesebenzayo yokususa isasasa.Ngoba akukho othintana naye, akukho arc, futhi akukho inani elikhulu lokushisa elikhiqizwayo, i-demagnetization inokwethenjelwa.Uma i-EMF yangemuva inkulu, isivinini sokuvala uzibuthe siyashesha.I-EMF yangemuva ekhiqizwe ngesikhathi sokuguqulwa kwebhuloho elilawula ngokugcwele lezigaba ezintathu ilingana ngokuqondile ne-voltage ye-AC side supply, ngakho-ke inani le-EMF elingemuva lilinganiselwe ngezinga elithile.Ngesikhathi esifanayo, i-max yokulawula enkulu (noma i-angle encane ye-inverter angle min) isethelwe ukuvimbela "ukuguqulwa kwe-inverter".Umkhawulo we) futhi wehlisa i-EMF engemuva ngokwezinga elithile.Ngakho-ke, i-inverter demagnetization eyodwa inqunyelwe amandla kagesi we-AC.Ngesikhathi se-inverter demagnetization, i-excitation current iyancipha ngokulandelana, kodwa inani le-back-EMF elisetshenzisiwe ngesikhathi se-inverter demagnetization lincane kunendlela yegridi yokucisha i-arc, ngakho-ke i-attenuates yamanje Izinga lincane, isikhathi sokuqeda uzibuthe side kakhulu, kodwa i-overvoltage multiple nayo iphansi kakhulu.

900kw diesel generator non-linear ukumelana demagnetization.

Lapho uhlelo lokuvusa amadlingozi luvalwa ngokujwayelekile, isilawuli sizosusa uzibuthe ngokuzenzakalelayo nge-inverter;uma ivalwa ngengozi, iswishi ye-demagnetization izogxuma ukuze idlulisele amandla kazibuthe kusimelaphi esidla amandla ukuze sinciphise uzibuthe.Uma ijeneretha isesimweni sokusebenza esingavamile njengokushelela, kuzokwenziwa i-voltage ephezulu kakhulu eyenziwe kumjikelezo we-rotor.Ngalesi sikhathi, i-rotor overvoltage discovery unit A61 module efakwe kumjikelezo we-rotor izobona isignali ye-rotor phambili ye-overvoltage futhi ngokushesha Icuphe isici se-V62 thyristor, ihlanganise i-resistor dissipation unit FR kumjikelezo we-rotor, futhi isuse amandla akhiqizwayo ngokweqile ngokusebenzisa. ukumuncwa kwamandla kwesinqanda ukushabalalisa amandla;kanye nesignali ye-reverse overvoltage ye-rotor circuit idlula ngokuqondile nge-tube yesibili ye-V61 I-resistor yokuchithwa kwamandla ixhunywe ukuze ibambe amandla ukuze kuqinisekiswe ukuthi i-rotor ye-generator ngeke ivule isifunda, ukuze ivikele ngokuthembekile ukufakwa kwe-rotor emonakalweni.Ngenxa yokuba khona kwalolu hlobo lokuvikela, ukujikajika kwe-rotor kuzokhiqiza inkambu kazibuthe ephambene, engasusa insimu yamagnetic ehlehlayo ekhiqizwa ukulandelana okungalungile kwamanje kwe-stator, ukuze kuvikelwe indawo ejikelezayo kanye nendandatho yokugada i-rotor kusuka. ukusha.

Indima ye-900kw generator generator magnetoresistance.

Ukuphenduka kwenjabulo kwe-a 900kw generator diesel iyikhoyili ene-inductance enkulu.Ngaphansi kwezimo ezivamile, i-excitation current ikhiqiza insimu enamandla kazibuthe ku-rotor ye-generator.Uma i-generator kadizili engu-900kw ihluleka ngaphakathi, kuyadingeka ukuthi inqamule ngokushesha i-excitation current futhi kukhishwe amandla kazibuthe egenerator kadizili engu-900kw ukugwema ukwanda kwengozi.Kodwa-ke, kunzima kakhulu ukusebenzisa ukushintshwa ukuze unqamule ngokuqondile okwamanje kumjikelezo onjalo nge-inductance enkulu kakhulu.Ngoba ukunqamula ngokuqondile umsinga ovusa amadlingozi kuzokhiqiza i-voltage ephezulu emikhawulweni yomibili ye-excitation winding, engashisa othintana nabo be-switch.Ngakho-ke, ngaphambi kokunqamula i-excitation circuit, qala ngokuxhuma ukumelana ne-de-excitation emikhawulweni yomibili ye-rotor ngokuhambisana, ukuze kuthi lapho i-excitation circuit inqanyulwa, ukumelana ne-de-excitation kungakwazi ukumunca ngokushesha amandla kazibuthe we-excitation winding. , yehlisa isivinini sokushintsha i-rotor yamanje, futhi unciphise i-rotor self Amandla e-electromotive eyenziwe adlala inhloso yokunciphisa i-rotor overvoltage kanye ne-demagnetization.

Ukumelana ne-de-excitation akukhona lapho igenerator kadizili engu-900kw ihambisana noma ingahlelwa kahle, kodwa uma kusetshenziswa ijeneretha kadizili engu-900kw, i-de-excitation resistor iyafakwa futhi ibekwe kuzo zombili iziphetho zekhoyili yerotor. iswishi esetshenziselwa ukunciphisa ngokushesha i-current ku-excitation circuit.Ngaphambi kokuqala ukwakha i-voltage, faka iswishi ye-de-excitation.Uma kwenzeka kuvaleka ijeneretha kadizili engu-900kw noma ingozi, sebenzisa iswishi yokususa isasasa ukuze unqamule amandla esekethe ye-excitation current ukuze ufeze inhloso yokwehlisa ngokushesha amandla kagesi ka-900kw generator.

umphumela:

(1) Iwukunqamula ngokushesha i-900kw generator generator excitation winding and excitation power path.

(2) Cisha ngokushesha amandla kazibuthe ngaphakathi kwejeneretha yedizili engu-900kw.

Okungenhla indlela yokuqeda uzibuthe kanye nokusebenza kuka-900kw generator diesel okwethulwa yi-Dingbo Power.Uma unentshisekelo kumajeneretha edizili, sicela uthinte i-Dingbo Powet nge-imeyili.I-Dingbo Power izokusebenzela ngokwethembeka.I-imeyili yethu ithi dingbo@dieselgeneratortech.com.
