Perkins Generator EMC Tsim Cov Qauv

Electromagnetic compatibility tsim qauv ntawm Perkins generator rau cov ntaub ntawv chaw siv.

(1) Siv tag nrho thiab muab kev ua si tag nrho rau cov khoom siv hluav taws xob sib raug zoo ntawm cov khoom siv hluav taws xob siv.Xws li: ① xaiv cov khoom siv hluav taws xob nrog lub teeb liab loj;② Xaiv cov khoom siv hluav taws xob uas tsim nyog;③ Txo cov input impedance ntawm input Circuit Court (tshwj xeeb tshaj yog cov chaw taws teeb input circuit) kom ntau li ntau tau;④ Txo cov zis impedance kom tsim nyog.

(2) Fais fab mov system tsim ntawm Perkins Diesel Generator yog tsim los ntawm cov neeg siv khoom .Xws li: ① xaiv lub hwj chim module nrog me me coupling capacitance ntawm thawj sab thiab theem nrab sab thiab loj coupling capacitance rau hauv av ntawm thawj sab;② Txais cov qauv tsim hluav taws xob ntau li ntau tau;③ Kev khiav hauj lwm ntau ntawm AC voltage ntawm lub hwj chim module yuav tsum loj txaus.

(3) Xaiv hom av.① Feem ntau, cov av ncaj qha tau txais yuav;② Thaum qhov kev tswj xyuas yog hluav taws xob txuas nrog cov cuab yeej siv hluav taws xob siab, lub hom phiaj hauv av tau txais yuav;③ Qhov kev faib tawm ntawm cov dej hauv av yuav tsum tau tswj xyuas nruj heev.

(4) Kev ua haujlwm ntawm kev faib cov peev txheej ntawm kev tswj hwm.① Sim txo qhov kev sib txuas ntawm qhov sib txuas ntawm cov thawj thiab theem nrab los thaiv txoj hauv kev ntawm kev cuam tshuam ntau yam;② Ib hom hom sib nqus hlau nplaum yog sheathed ntawm qhov chaw nkag ntawm qhov chaw nres nkoj, thiab tom qab ntawd muaj qhov sib npaug ntawm qhov muaj peev xwm ua tau zoo rau hauv av;③ Khaws cov xaim hauv av kom deb ntawm lwm cov xov tooj ntawm tes;④ Txo qhov kev faib tawm ntawm qhov system;⑤ Ntsuam xyuas qhov kev faib tawm ntawm txhua qhov chaw rau hauv av, txheeb xyuas qhov kev faib tawm ntawm cov kev cuam tshuam ntau yam, kwv yees qhov cuam tshuam ntawm kev cuam tshuam ntawm hom kev cuam tshuam, thiab tsim cov kev ntsuas kev cuam tshuam.

Dab tsi yog qhov tseem ceeb ntawm cov cim qhia ntawm cov teeb liab loj thiab cov teeb liab me me?

Lub ntsiab technical indexes ntawm excitation system muaj xws li:

(1) Cov ntsiab lus tseem ceeb ntawm cov yam ntxwv ntawm cov teeb liab loj: ① rau cov lus teb rau cov lus teb excitation system, cov kev indexes yog sab saum toj voltage ntau thiab excitation voltage teb piv;② Rau lub excitation system nrog siab pib teb, cov kev indexes yog lub sab saum toj voltage ntau thiab excitation voltage teb lub sij hawm.

(2) Cov ntsiab lus tseem ceeb ntawm cov yam ntxwv ntawm cov teeb liab me me yog: lub sijhawm nce, lub sijhawm hloov kho, overshoot thiab oscillation lub sijhawm.Tus qauv ntsuas yog: overshoot ≤ 50%, hloov lub sij hawm ≤ IOS, oscillation zaus ≤ 3 zaug.

Vim li cas ntsuas lub rotor ceev-up rwb thaiv tsev thaum lub tshuab hluav taws xob pib?Rau qee lub tshuab hluav taws xob rotors, qhov txhaum hauv av ntawm lub tshuab hluav taws xob rotor winding feem ntau cuam tshuam nrog lub zog centrifugal thaum lub rotor tig, tab sis qhov kev ua txhaum no tsis tuaj yeem cuam tshuam rau hauv kev sim hauv qab kaw.Yog li ntawd, thaum lub tshuab hluav taws xob nce los ntawm xoom nrawm mus rau qhov ntsuas ceev, ntsuas qhov rwb thaiv tsev ntawm rotor winding nyob rau theem no tuaj yeem txiav txim siab seb puas muaj qhov yuam kev hauv rotor winding, yog li txhawm rau txheeb xyuas qhov txhaum thiab xyuas kom meej tias tsis muaj kev phom sij zais hauv. kev ua haujlwm ntawm rotor winding.

Semiconductor excitation regulator

Nyob rau hauv lub semiconductor excitation system, lub zog excitation unit yog lub semiconductor rectifier thiab nws cov AC fais fab mov, thiab cov excitation regulator yog tsim los ntawm semiconductor Cheebtsam, khoom Cheebtsam thiab hluav taws xob circuits.Lub regulator thaum ntxov tsuas yog xav txog lub tshuab hluav taws xob qhov sib txawv ntawm qhov hluav taws xob thiab nqa tawm qhov hloov kho voltage.Nws feem ntau hu ua voltage regulator (voltage regulator luv luv).Lub regulator tam sim no muaj peev xwm ua tiav muaj kev cuam tshuam ntau yam kev tswj cov teeb liab nrog rau qhov sib txawv ntawm qhov hluav taws xob rau kev tswj xyuas excitation, yog li nws yog hu ua excitation regulator.Obviously, lub excitation regulator suav nrog kev ua haujlwm ntawm voltage regulator.
