Yuav daws qhov teeb meem luv luv ntawm Volvo Diesel Generator Teeb li cas

Volvo diesel generator teeb tsis tshua muaj teeb meem luv luv thaum siv.Cov laj thawj tseem ceeb yog dab tsi thiab yuav daws li cas?100KW generator chaw tsim tshuaj paus koom nrog koj.

1. Cov yam ntxwv ntawm tam sim no luv luv Circuit Court.

Nyob rau hauv cov ntaub ntawv ntawm ib tug ruaj khov-lub xeev luv luv-circuit, vim lub loj synchronous reactance, lub ruaj khov-lub xeev luv-circuit tam sim no tsis loj, thiab nyob rau hauv cov ntaub ntawv ntawm ib tug tam sim ntawd luv-circuit, vim hais tias lub super-transient reactance txwv lub tam sim no yog me me thiab muaj cov khoom siv ncaj qha tam sim no, tam sim no luv luv-circuit tam sim no loj, Nws cov nqi siab tshaj tuaj yeem ncav cuag ntau tshaj kaum npaug ntawm qhov ntsuas tam sim no.

Nrog rau qhov tshwm sim ntawm qhov tam sim no inrush tam sim no, lub windings ntawm lub cev muaj zog yuav raug rau ib tug loj cuam tshuam electromagnetic quab yuam, uas tej zaum yuav deform lub windings thiab txawm ua puas lub rwb thaiv tsev ntawm lub windings.

Nyob rau hauv tus txheej txheem ntawm ib tug tam sim ntawd luv luv Circuit Court, lub cev muaj zog raug rau ib tug luv luv-circuit torque, thiab kev co yuav tshwm sim.

Lub stator thiab rotor windings ntawm lub cev muaj zog overvoltage.

2. Cov yam ntxwv ntawm lub cev phenomena nyob rau hauv lub lub tshuab hluav taws xob thaum lub caij luv luv.

Nyob rau hauv cov ntaub ntawv ntawm ib tug ruaj khov-lub xeev luv luv-circuit, lub armature tam sim no yog tas li, thiab cov coj armature magnetomotive quab yuam yog ib tug tas li amplitude rotating magnetic teb rotating ntawm ib tug synchronous ceev, yog li nws yuav tsis induce electromotive quab yuam nyob rau hauv lub rotor windings thiab tsim. tam sim no.Los ntawm kev sib raug zoo tam sim no Saib, nws yog sib npaug rau lub xeev qhib ntawm lub transformer.

Thaum lub caij luv luv tam sim no tshwm sim, qhov loj ntawm lub armature tam sim no hloov, thiab qhov sib txuam armature magnetic field amplitude hloov.Yog li ntawd, lub transformer ua ntawm lub stator thiab lub rotor, uas induces hluav taws xob muaj peev xwm thiab tam sim no nyob rau hauv lub rotor windings, thiab ces cuam tshuam cov stator windings.Los ntawm qhov kev xav ntawm electromagnetic kev sib raug zoo, qhov kev hloov ntawm nruab nrab tam sim no yog sib npaug rau tam sim ntawd luv luv-circuit xeev ntawm lub transformer.

Thaum lub sij hawm tsim hluav taws xob ib txwm muaj ntawm Volvo diesel generator teeb, cov khoom siv hluav taws xob dheev luv luv-circuited thiab lub foob pob hluav taws loj tshwm sim, uas ua rau lub tshuab hluav taws xob hluav taws xob thiab zaus ploj, thiab lub tshuab hluav taws xob tau pib mus rau qhov ntsuas nrawm dua, thiab lub tshuab hluav taws xob. tsis tuaj yeem tsim hluav taws xob.

Failure analysis:

Tom qab tus neeg teb xov tooj lossis tus neeg saib xyuas pom qhov ua txhaum cai no, lawv yuav tsum kuaj xyuas qhov excitation fuse ua ntej, thiab tom qab ntawd xyuas lub tshuab hluav taws xob stator, exciter thiab generator tswj qhov chaw.Tsuas yog tom qab lees paub tias tsis muaj qhov puas tsuaj tuaj yeem pib lub cav diesel.Yog tias lub tshuab hluav taws xob tsis tsim hluav taws xob, qhov seem magnetization voltage ntawm exciter yuav tsum tau kuaj xyuas.

Ua rau faults:

(1) Muaj qhov qhib Circuit Court lossis luv luv hauv lub exciter.

(2) Lub excitation fuse qhib.

(3) Ob lub raj tawg.

(4) Muaj qhov luv luv lossis qhib Circuit Court hauv lub reactor.

(5) Cov hlau nplaum seem ntawm cov exciter ploj mus.

Txoj kev daws teeb meem:

Kev tswj ib feem ntawm lub tshuab hluav taws xob lub tshuab hluav taws xob no tau txais cov theem kev sib xyaw ua ke tsis siv neeg hluav taws xob tsis siv neeg hluav taws xob, yog li thaum daws qhov teeb meem no, nws yuav tsum nkag siab lub hauv paus ntsiab lus ntawm theem kev sib txuas excitation tsis siv neeg hluav taws xob tswj kev tswj hwm thiab cov khoom sib xyaw thiab lub luag haujlwm ntawm txhua qhov kev ua haujlwm, thiab tom qab ntawd ua raws cov kauj ruam los ntawm qhov yooj yim mus rau Lub hauv paus ntsiab lus ntawm kev tshuaj xyuas nyuaj.

(1) Tshawb xyuas lub fuse thiab pom tias lub fuse tau tawg lawm.Saib xyuas seb cov khoom hauv lub thawv tswj tau scorched.Thaum lub sij hawm soj ntsuam, nws pom tias qhov txwv-tam sim no ob lub raj raug hlawv tawm.

(2) Siv lub multimeter los ntsuas lub 6 rectifier diodes, thiab tsis muaj qhov txawv txav los ntawm cov txiaj ntsig kev xeem.

(3) Siv lub tshuab ntsuas ntau los ntsuas qhov kev tawm tsam ntawm exciter, thiab ntsuas qhov ntsuas yog 3.5Ω, uas qhia tau hais tias lub zog sab hauv ntawm lub exciter puas lawm (qhov kev tiv thaiv ib txwm yog li 0.5Ω).

(4) Tom qab hloov qhov thib ob tam sim no limiting raj thiab lub fuse, thaum lub cav diesel pib mus rau qhov ntsuas ceev, lub tshuab hluav taws xob yuav tsis tsim hluav taws xob.

Qhov no qhia tau hais tias qhov txhaum yuav yog tias qhov hluav taws xob sab hauv ntawm lub exciter yog tsawg dhau (hauv cov txheej txheem ntawm kev tsim hluav taws xob ib txwm muaj, cov khoom siv hluav taws xob tam sim ntawd luv luv-circuits thiab lub foob pob hluav taws loj tshwm sim, uas yuav ua rau lub zog sab hauv remanence ntawm lub exciter. kom ploj.

(5) Tom qab magnetizing lub exciter nrog lub roj teeb, pib lub cav diesel mus rau qhov ntsuas ceev, thiab lub tshuab hluav taws xob yuav pib tsim hluav taws xob thiab ua tau raws li qhov yuav tsum tau ua.
