Generator Chaw tsim tshuaj paus Kev tiv thaiv tawm

Lub tshuab hluav taws xob stator hauv av txhaum kev tiv thaiv rau lub tshuab hluav taws xob stator ib-theem hauv av txhaum kev tiv thaiv, peb zaug los ntawm qee qhov tseem ceeb xoom kab ke voltage thiab harmonic voltage ntawm ob qhov chaw, thawj harmonic zero sequence voltage tiv thaiv tshuab tail kawg rau 95% cheeb tsam ntawm stator winding ib leeg- theem grounding txhaum, qhov cuam tshuam lub hwj chim qauv nyob rau hauv lub zero sequence voltage txoj cai, los ntawm lub sij hawm t1 (3 s) teev tawm lub sib nqus ua nyob rau hauv kev daws;Qhov thib peb harmonic voltage tiv thaiv lub stator winding ib-theem grounding txhaum los ntawm tus Tsov tus tw mus rau 30% ntawm lub kawg ntawm lub tshuab, uas yog tsim los ntawm generator nruab nrab point thiab lub hauv paus ntsiab lus ntawm lub thib peb harmonic ntawm lub kawg ntawm lub tshuab, thiab ua rau lub teeb liab dhau lub sij hawm t2 (5s).Ob leeg yog 100% stator grounding tiv thaiv.Kev tiv thaiv yog nruab nrog PT hlau tawg xauv.

Stator tig tig tiv thaiv lub tshuab hluav taws xob

Kev tiv thaiv yog tsim los ntawm longitudinal xoom-sequence voltage thiab tsis zoo ib ntus kev taw qhia kev ntsuas ntawm kev faib ua txhaum.PT disconnection thaiv kev ntsuas yog teem raws li lub ntsiab tiv thaiv ntawm inter-tig, inter-theem luv luv Circuit Court thiab stator winding qhib vuam nyob rau hauv lub generator.Qhov kev ua txhaum ntawm qhov tsis zoo ib ntus kev taw qhia cov txheej txheem paub txog qhov longitudinal zero sequence voltage criterion realizes lub longitudinal 3U0 tso zis los ntawm 3PT qhib daim duab peb sab winding uas yog ncaj qha txuas mus rau lub tshuab hluav taws xob nruab nrab tab sis tsis grounded los ntawm kev kuaj xyuas qhov tsis zoo ib ntus lub zog ntawm lub tshuab hluav taws xob.Kev tiv thaiv nres txhua.

Generator Chaw tsim tshuaj paus kev tiv thaiv tawm ntawm cov kauj ruam

Kev tiv thaiv siv peb lub ntsiab lus impedance, los ntawm kev hloov pauv ntawm impedance los kuaj xyuas tus lej ntawm tus ncej thiab txiav txim siab qhov chaw ntawm qhov chaw oscillation.Nyob rau hauv cov ntaub ntawv ntawm luv luv Circuit Court txhaum, system oscillation, voltage Circuit Court break, thiab lwm yam., tiv thaiv tsis ua hauj lwm.Tiv thaiv kev ua haujlwm ntawm lub teeb liab;Thaum lub chaw oscillation yog nyob rau hauv lub tshuab hluav taws xob thiab transformer pab pawg neeg, qhov kev tiv thaiv seem kuv pib xa cov tripping hais kom ua los ntawm T1 (0.5s), thiab qhov kev txiav txim yog deactivate lub magnetic teb.Thaum lub chaw oscillation nyob sab nraum lub tshuab hluav taws xob-transformer teeb, qhov kev tiv thaiv II tau pib teeb liab los ntawm T2 (2S).Kev tiv thaiv yog nruab nrog lub ntsuas ntsuas tam sim no los xyuas kom meej tias tam sim no tsis tshaj qhov ntsuas tawm ntawm cov kauj ruam tawg tam sim no ntawm Circuit Court breaker thaum lub Circuit Court breaker tawm.

Tsawg zaus accumulative tiv thaiv

Tsawg zaus tsub zuj zuj ntawm kev tiv thaiv cov tshuaj tiv thaiv ntau zaus los txo cov kev cuam tshuam ntawm qhov cuam tshuam ntawm lub tshuab hluav taws xob, kev tiv thaiv yog tsim los ntawm cov zaus zaus relay thiab txee, xauv lub qhov hluav taws xob Circuit Court breaker auxiliary contacts (uas yog, tsawg zaus lub tshuab hluav taws xob tawm ntawm lub sijhawm ua haujlwm sib txuas thiab txiav tawm khiav), cov kab ke sib txuas ntau zaus qis dua 47.5 Hz zaus teeb tsa lub sijhawm, thaum lub sijhawm teeb tsa tag nrho rau 3000 vib nas this, Teeb liab yuav raug xa tom qab 30 vib nas this ncua.Cov cuab yeej tuaj yeem saib xyuas hauv lub sijhawm tiag tiag thaum lub sijhawm ua haujlwm: tus nqi tas li, zaus F thiab lub sijhawm ua kom pom.Kev tiv thaiv sib txawv ntawm lub tshuab hluav taws xob thiab cov khoom siv hluav taws xob sib txawv, kev tiv thaiv kev sib txawv ntawm kev hloov pauv thiab kev tiv thaiv kev sib txawv siab yog qhov tseem ceeb ntawm kev tiv thaiv kev cuam tshuam luv luv ntawm cov khoom tiv thaiv, siv qhov sib piv nres txoj cai.Qhov kev ua txhaum tawm ntawm thaj chaw tuaj yeem ntseeg tau kom zam dhau qhov tsis sib xws tam sim no tsim los ntawm qhov tsis sib xws ntawm CT yam ntxwv ntawm txhua sab, thiab kev tiv thaiv hauv cheeb tsam tuaj yeem ua tau zoo.Txhawm rau kom tsis txhob muaj kev tiv thaiv kev ua haujlwm tsis zoo nyob rau hauv transformer inrush tam sim no, kev tiv thaiv tau txais kev sib haum xeeb thib ob.Kev tiv thaiv yog nruab nrog kev ua haujlwm ntawm kev thaiv qhov sib txawv ntawm qhov sib txawv tsis muaj qhov sib txawv thib ob, thiab qhov txhaum tuaj yeem raug tshem tawm tam sim ntawd thaum qhov sib txawv tam sim no mus txog qhov teeb tsa tus nqi.Kev tiv thaiv muaj CT kab tawg locking muaj nuj nqi (tsis siv tiag).CT kab tawg kev ntxub ntxaug yog tib yam li lub tshuab hluav taws xob sib txawv tiv thaiv.

Guangxi Dingbo Power Equipment Manufacturing Co., Ltd. tsim nyob rau hauv 2006, yog ib lub chaw tsim tshuaj paus ntawm diesel generator nyob rau hauv Suav teb, uas integrates tsim, muab, commissioning thiab txij nkawm ntawm diesel generator teeb.Cov khoom npog Cummins, Perkins, Volvo, Yuchai, Shangchai, Deutz , Ricardo, MTU, Weichai thiab lwm yam nrog lub hwj chim ntau 20kw-3000kw, thiab dhau los ua lawv lub Hoobkas OEM thiab lub chaw thev naus laus zis.
