Txoj Kev Demagnetization thiab Kev Ua Haujlwm ntawm 900kw Diesel Generator

900kw diesel generator, raws li a high-power generator teeb , muaj tag nrho lub zog thiab lub zog muaj zog.Nyob rau tib lub sijhawm, raws li lub tshuab hluav taws xob diesel teeb, nws muaj cov yam ntxwv ntawm kev ua haujlwm yooj yim thiab kev saib xyuas yooj yim.Koj paub ntau npaum li cas txog txoj kev demagnetization thiab kev ua haujlwm ntawm 900kw diesel generator?

Lub 900kw diesel generator ua de-excitation.

Siv lub inverter ua hauj lwm lub xeev ntawm peb-theem tag nrho-tswj choj, lub kaum sab xis tswj tau hloov los ntawm lub rectifying lub xeev ntawm tsawg tshaj li 90 ° mus rau ib tug tsim nyog lub kaum sab xis ntau dua 90 °.Lub sijhawm no, lub zog excitation tau hloov pauv thiab siv rau qhov excitation winding hauv daim ntawv rov qab EMF., Cov txheej txheem de-excitation uas rotor tam sim no sai sai rau xoom hu ua inverter de-excitation.Txoj kev de-excitation no sai sai rov qab lub rotor zog cia rau AC sab fais fab mov ntawm peb-theem tag nrho-tswj choj, thiab tsis tas yuav tsum tau tawm resistors los yog arc extinguishing daim phiaj.Nws yog ib qho yooj yim thiab siv tau de-excitation txoj kev.Vim tias tsis muaj kev sib cuag, tsis muaj arc, thiab tsis muaj cov cua kub ntau, cov demagnetization yog txhim khu kev qha.Qhov ntau dua qhov rov qab EMF, qhov ceev ntawm demagnetization ceev.Lub nraub qaum EMF generated thaum lub sij hawm inversion ntawm peb-theem tag nrho-tswj choj yog ncaj qha proportional rau qhov voltage ntawm AC sab fais fab mov, yog li tus nqi ntawm lub nraub qaum EMF yog txwv rau qee yam.Nyob rau tib lub sij hawm, qhov loj tswj max (los yog me me inverter lub kaum sab xis min) yog teem los tiv thaiv "inverter subversion".Qhov kev txwv ntawm) kuj txo qis EMF rov qab rau qee yam.Yog li ntawd, ib qho inverter demagnetization yog txwv los ntawm AC lub zog hluav taws xob.Thaum lub sij hawm inverter demagnetization, lub excitation tam sim no txo ​​qis linearly, tab sis cov ntaub ntawv rov qab-EMF tus nqi thaum lub sij hawm inverter demagnetization yog me dua li ntawm arc extinguishing daim phiaj demagnetization txoj kev, yog li tam sim no attenuates tus nqi me me, lub sij hawm demagnetization kuj ntev, tab sis lub overvoltage ntau kuj tseem tsawg heev.

900kw diesel generator tsis-linear kuj demagnetization.

Thaum lub kaw lus excitation raug kaw ib txwm, lub regulator yuav cia li demagnetize los ntawm inverter;Yog tias nws raug kaw los ntawm kev sib tsoo, qhov hloov pauv demagnetization yuav dhia kom hloov lub zog sib nqus mus rau lub zog siv hluav taws xob kom demagnetize.Thaum lub tshuab hluav taws xob nyob rau hauv ib qho kev ua haujlwm txawv txav xws li slipping, lub siab induced voltage yuav raug generated nyob rau hauv lub rotor circuit.Lub sijhawm no, lub rotor overvoltage detection unit A61 module ntsia rau hauv lub rotor Circuit Court yuav ntes lub rotor rau pem hauv ntej overvoltage teeb liab thiab tam sim ntawd ua rau lub V62 thyristor caij, integrate lub zog dissipation resistor unit FR rau hauv lub rotor circuit, thiab tshem tawm cov generated overvoltage zog los ntawm lub zog nqus ntawm lub zog dissipation resistor;thiab rov qab overvoltage teeb liab ntawm lub rotor Circuit Court ncaj qha dhau los ntawm V61 ob lub raj Lub zog dissipation resistor txuas nrog nqus lub zog los xyuas kom meej tias lub tshuab hluav taws xob rotor yuav tsis qhib Circuit Court, thiaj li tiv thaiv cov rotor rwb thaiv tsev los ntawm kev puas tsuaj.Vim muaj kev tiv thaiv zoo li no, lub rotor winding yuav tsim ib qho chaw sib nqus sib nqus, uas tuaj yeem cuam tshuam qhov rov qab magnetic teb generated los ntawm qhov tsis zoo ib ntus tam sim no ntawm stator, thiaj li tiv thaiv lub rotor nto thiab lub nplhaib rotor guard. kub tawm.

Lub luag haujlwm ntawm 900kw diesel generator magnetoresistance.

Lub excitation winding ntawm a 900kw diesel generator yog ib tug coil nrog ib tug loj inductance.Raws li ib txwm muaj, qhov excitation tam sim no ua rau muaj zog sib nqus ntawm lub tshuab hluav taws xob rotor.Thaum lub 900kw diesel generator tsis ua haujlwm sab hauv, nws yog ib qho tsim nyog yuav tsum tau txiav tawm sai sai thiab tshem tawm cov hlau nplaum ntawm 900kw diesel generator kom tsis txhob muaj qhov nthuav dav.Txawm li cas los xij, nws yog qhov nyuaj heev los siv qhov hloov mus ncaj qha los txiav tawm tam sim no hauv ib lub voj voog uas muaj qhov inductance loj heev.Vim hais tias ncaj qha txiav tawm lub excitation tam sim no yuav ua kom muaj hluav taws xob siab ntawm ob qho kawg ntawm excitation winding, uas tuaj yeem hlawv cov kev sib cuag.Yog li ntawd, ua ntej txiav tawm lub excitation Circuit Court, ua ntej txuas lub de-excitation tsis kam ntawm ob qho kawg ntawm lub rotor nyob rau hauv parallel, thiaj li hais tias thaum lub excitation Circuit Court raug txiav tawm, lub de-excitation kuj yuav sai sai nqus lub zog sib nqus ntawm excitation winding. , qeeb lub rotor tam sim no hloov ceev, thiab txo tus rotor nws tus kheej Lub induced electromotive quab yuam plays lub hom phiaj ntawm txo lub rotor overvoltage thiab demagnetization.

Lub de-excitation kuj tsis yog thaum lub 900kw diesel generator yog paralleled los yog de-tawm, tab sis thaum siv 900kw diesel generator, de-excitation resistor yog input thiab muab tso rau ntawm ob kawg ntawm lub rotor coil.Qhov de-excitation hloov yog ib qho kev hloov pauv siv los txo qhov tam sim no hauv lub excitation circuit.Ua ntej pib tsim qhov voltage, muab tso rau hauv lub de-excitation hloov.Nyob rau hauv qhov kev tshwm sim ntawm 900kw diesel generator kaw los yog kev huam yuaj, mus rau lub de-excitation hloov mus txiav tawm lub excitation Circuit Court tam sim no kom ua tiav lub hom phiaj ntawm sai txo qhov voltage ntawm 900kw diesel generator.
