Yuav ua li cas Magnetize lub Generator

Yog tias lub tshuab hluav taws xob tsis yog hlau nplaum, nws tuaj yeem sib nqus nrog 12V roj teeb.Txoj kev tshwj xeeb yog: txuas ob lub xov hlau los ntawm + - ncej ntawm lub roj teeb.Qhib cov ntaub ntawv tiv thaiv hlau ntawm lub tshuab hluav taws xob tswj Circuit Court board.Pib lub tshuab hluav taws xob.Txuas lub + - ncej rau F + F - (ntawm lub tshuab hluav taws xob tswj Circuit Court board, thiab lub sijhawm sib txuas yuav tsum tsis pub dhau ib thib ob. Tom qab kev sib nqus, xyuas qhov voltage thiab zaus. ua kom tiav, thiab tom qab ntawd nws tuaj yeem thauj khoom tom qab kuaj xyuas kom zoo li qub, lwm rooj plaub yog pib lub tshuab hluav taws xob thiab nws yuav them tau li ntawm kaum feeb.

Tab sis yog tias lub tshuab hluav taws xob poob excitation vim muaj teeb meem faults, peb yuav tsum daws nws raws li qhov sib txawv faults.

Dab tsi yog qhov ua rau lub tshuab hluav taws xob poob ntawm excitation?

Thaum lub sij hawm ib txwm ua hauj lwm ntawm lub tshuab hluav taws xob, lub excitation dheev disappears nyob rau hauv tag nrho los yog ib feem, uas yog hu ua qhov poob ntawm excitation ntawm lub generator.Qhov ua rau lub tshuab hluav taws xob poob ntawm excitation feem ntau tuaj yeem suav hais tias yog qhib Circuit Court lossis luv Circuit Court ntawm excitation Circuit Court, nrog rau kev ua tsis tiav ntawm exciter, excitation transformer los yog excitation Circuit Court, txhob txwm kov ntawm excitation hloov, tsis raug hloov ntawm standby excitation, poob ntawm pab fais fab mov. excitation system, qhib Circuit Court ntawm rotor winding los yog excitation Circuit Court los yog luv luv Circuit Court ntawm rotor winding, tsis ua hauj lwm ntawm semiconductor excitation system, ignition los yog hlawv ntawm rotor swb nplhaib.

1. Excitation transformer fault trip ua rau lub tshuab hluav taws xob poob ntawm excitation

Vim lub rwb thaiv tsev tsim tsis xws luag ntawm lub transformer los yog maj mam deterioration ntawm lub rwb thaiv tsev tsis xws luag thaum lub sij hawm ua hauj lwm, qhov paug tshwm sim tshwm sim, uas ua rau lub tripping ntawm lub excitation transformer tiv thaiv kev txiav txim thiab lub tripping ntawm lub tsev vim poob ntawm excitation tiv thaiv kev txiav txim.Cov txheej txheem thiab cov qauv yuav tsum tau ua nruj me ntsis, thiab kev ntsuam xyuas tsis tu ncua, kev siv thiab kev daws teeb meem yuav tsum tau ua.Raws li cov kev cai thiab cov qauv, kev ua raws sij hawm ntawm kev ntsuam xyuas ntawm rwb thaiv tsev yuav tsum ua tib zoo ua.

2. Excitation poob ntawm lub tshuab hluav taws xob los ntawm tripping ntawm de excitation hloov

Yog vim li cas rau qhov kev mus ncig ntawm de excitation hloov muaj xws li: (1) cov lus txib mus txawv tebchaws ntawm de excitation hloov tau yuam kev xa mus rau DCS.(2) Tripping hais kom ua ntawm deexcitation hloov yog xa tawm nyob rau hauv cov ntaub ntawv ntawm txhaum ntawm qhov hluav taws xob relay.(3) Cov kev sib cuag ntawm lub pob mus txawv tebchaws ntawm lub de excitation hloov ntawm lub vaj huam sib luag ntsug hluav taws xob hauv chav tswj hwm hauv nruab nrab yog rub tawm los xa tawm cov lus txib mus txawv tebchaws.(4) Lub zos tswj vaj huam sib luag ntawm chav excitation manually cais lub de excitation mus.(5) Lub rwb thaiv tsev ntawm kev tswj Circuit Court cable ntawm de excitation hloov poob.(6) Lub cev hloov lub cev mechanically mus rau qhov de excitation hloov.(7) Lub hauv paus tam sim ntawd ntawm DC system ua rau lub de excitation hloov mus rau lwm qhov.

3. Poob excitation ntawm generator tshwm sim los ntawm ignition ntawm excitation plam nplhaib

Qhov ua rau muaj kev huam yuaj yog tias lub siab ntawm cov pa roj carbon txhuam compression caij nplooj ntoos hlav tsis sib xws, ua rau tsis sib xws tam sim no ntawm qee cov pa roj carbon txhuam, ua rau cov pa roj carbon ntau dhau tam sim no thiab ua rau muaj cua sov.Tsis tas li ntawd, cov pa roj carbon txhuam yog qias neeg, ua paug rau qhov chaw sib cuag ntawm cov pa roj carbon txhuam thiab lub nplhaib plam, ua rau kev sib cuag ntawm qee cov pa roj carbon txhuam thiab lub nplhaib nplawm kom nce thiab ces sparking.Tsis tas li ntawd, qhov hnav ntawm qhov zoo thiab qhov tsis zoo carbon txhuam yog qhov tsis sib xws, thiab kev hnav ntawm qhov tsis zoo electrode yog ib txwm hnyav dua li qhov zoo electrode.Qhov saum npoo roughness ntawm lub nplhaib ntiv nplhaib yog nce vim qhov hnyav hnyav, thiab lub nplhaib ntiv nplhaib hluav taws yog tshwm sim los ntawm kev tswj tsis tau raws sijhawm.

4. Kev poob ntawm excitation ntawm lub tshuab hluav taws xob los ntawm grounding ntawm DC system

Tom qab qhov zoo electrode grounding ntawm DC system, lub cable ntev tau faib capacitance, thiab qhov voltage ntawm ob qho kawg ntawm lub capacitance tsis tuaj yeem hloov tam sim ntawd, uas ua rau lub capacitance tam sim no ntawm lub cable ntev nyob rau hauv sab nraud tripping circuit ntawm lub tshuab hluav taws xob deexcitation hloov mus rau. ntws los ntawm nruab nrab relay nyob rau sab nraud tripping qhov hluav taws xob, thiab lub relay ua mus rau lub generator deexcitation hloov, uas ua rau lub tripping ntawm lub generator deexcitation tiv thaiv kev txiav txim.

5. Poob excitation ntawm lub tshuab hluav taws xob tshwm sim los ntawm kev ua txhaum ntawm excitation regulation system

Kev ua txhaum ntawm EGC pawg thawj coj ntawm lub tshuab hluav taws xob excitation system regulator ua rau muaj kev tiv thaiv tshaj qhov hluav taws xob ntawm lub rotor ntawm lub tshuab hluav taws xob excitation regulator, uas ua rau lub tripping poob ntawm excitation tiv thaiv kev txiav txim.
