Dab tsi yog Reverse Power Protection of Generator Set

Raws li tus tswv thiab cov neeg siv ntawm lub tshuab hluav taws xob teeb, tus neeg siv yuav tsum nkag siab txhua yam ntawm lub tshuab hluav taws xob teeb, thiaj li ua tau zoo rau kev ua haujlwm thiab siv cov txheej txheem ntawm lub tshuab hluav taws xob.Niaj hnub no Dingbo Power tuam txhab qhia rov qab lub zog tiv thaiv ntawm lub tshuab hluav taws xob teeb.

Lub tshuab hluav taws xob teeb rov qab tiv thaiv hluav taws xob tseem hu ua kev tiv thaiv hluav taws xob.Feem ntau hais lus, lub zog kev taw qhia ntawm lub tshuab hluav taws xob yuav tsum yog los ntawm lub tshuab hluav taws xob mus rau lub tsheb npav.Txawm li cas los xij, thaum lub tshuab hluav taws xob poob siab lossis rau qee qhov laj thawj, lub tshuab hluav taws xob yuav hloov mus rau lub cev muaj zog, uas yog, nqus lub zog los ntawm lub cev, uas yog lub zog rov qab.Thaum lub hwj chim rov qab mus txog ib qho nqi, kev tiv thaiv ntawm lub tshuab hluav taws xob ua haujlwm, lossis ua rau lub teeb liab lossis kev mus ncig.

Kev ua haujlwm sib luag ntawm ob lub tshuab hluav taws xob diesel yuav tsum ua raws li cov xwm txheej ntawm tib theem ntawm lub tshuab hluav taws xob voltage, tib zaus ntawm hluav taws xob generator thiab tib theem sequence ntawm generator teeb.Hauv kev siv tiag tiag, thaum ob lub tshuab hluav taws xob diesel teeb ua ke tsis muaj kev thauj khoom, yuav muaj teeb meem ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv voltage.Qee lub sij hawm lub zog rov qab tiag tiag yuav pom nrog cov ntsuas ntsuas, uas yog lub zog rov qab los ntawm qhov tsis sib xws.Lwm qhov yog qhov rov qab ua haujlwm los ntawm qhov tsis sib xws ntawm qhov nrawm (ntau zaus).Nyob rau hauv lub ntsej muag ntawm qhov tshwm sim, cov kev hloov kho yuav tsum tau ua.

1.Kev hloov ntawm lub zog rov qab los ntawm qhov sib txawv voltage.

Thaum lub hwj chim ntsuas qhov taw qhia ntawm ob qho kev tsim hluav taws xob yog xoom thiab lub ammeter tseem muaj qhov taw qhia tam sim no, qhov hloov kho qhov hluav taws xob ntawm ib lub tshuab hluav taws xob diesel tuaj yeem hloov kho raws li qhov qhia ntawm ammeter thiab lub zog hluav taws xob.

2.Kev hloov ntawm lub zog rov qab los ntawm cov zaus.

Yog tias qhov zaus ntawm ob chav nyob sib txawv thiab qhov sib txawv loj, qhov tam sim no ntawm chav tsev nrog kev kub ceev qhia txog tus nqi zoo thiab lub ntsuas hluav taws xob qhia tau hais tias lub zog zoo.Ntawm qhov tsis sib xws, tam sim no qhia tus nqi tsis zoo thiab lub zog qhia qhov tsis zoo.

Lub sijhawm no, kho qhov ceev ntawm ib qho ntawm lub tshuab hluav taws xob diesel teeb thiab kho qhov taw qhia ntawm lub ntsuas hluav taws xob mus rau xoom.Txawm li cas los xij, thaum lub ammeter tseem muaj qhov taw qhia, qhov no yog qhov rov qab fais fab tshwm sim los ntawm qhov sib txawv voltage.

Feem ntau, kev sib txuas ntawm cov tshuab hluav taws xob diesel yuav tsis tsim hluav taws xob rov qab.Tsuas yog ob peb lub tshuab hluav taws xob muaj qhov hluav taws xob qis qis vim muaj kev tswj hwm tsis raug thaum txuas nrog daim phiaj.Peb yuav tsum txheeb xyuas cov laj thawj kom sai li sai tau thiab ua cov kev ntsuas kom haum.

Dab tsi yog lub luag haujlwm ntawm lub tshuab hluav taws xob thim rov qab tiv thaiv hluav taws xob?

Thaum ntau tshaj ob lub tshuab hluav taws xob siv hluav taws xob ua haujlwm ua ke, yog tias lub tshuab hluav taws xob ntawm ib lub tshuab hluav taws xob diesel tsis ua haujlwm ib txwm lossis cov khoom sib txuas ntawm lub tshuab hluav taws xob thiab lub tshuab hluav taws xob puas lawm, lub tshuab hluav taws xob ntawm chav tsev tsis tuaj yeem tso tawm lub zog, tab sis nqus tau. lub zog los ntawm lub zog hluav taws xob, thiab lub tshuab hluav taws xob synchronous dhau los ua lub tshuab hluav taws xob synchronous, uas yog, lub tshuab hluav taws xob synchronous ua haujlwm hauv lub zog rov qab.

Yog hais tias lub tshuab hluav taws xob synchronous ua haujlwm nyob rau hauv lub zog rov qab, nws tsis zoo rau cov khoom siv hluav taws xob, uas ua rau muaj kev cuam tshuam ntau dhau ntawm lwm cov units koom nrog. kev ua haujlwm sib luag thiab fais fab mov cuam tshuam.Yog li, kev ntsuas yuav tsum tau ua rau kev tiv thaiv hluav taws xob rov qab.

Peb tuaj yeem siv transistor rov qab fais fab kev tiv thaiv ntaus ntawv.

Txij li kev tiv thaiv hluav taws xob thim rov qab yog kev tiv thaiv kev tiv thaiv hluav taws xob, nws cov teeb liab pom yuav tsum coj cov teeb liab ntawm qhov hluav taws xob thiab tam sim no thiab lawv cov theem kev sib raug zoo, thiab hloov nws mus rau hauv DC voltage tswj teeb liab qhia txog cov kev taw qhia thiab qhov loj ntawm lub zog nquag.

Lub teeb liab tiv thaiv hluav taws xob rov qab ntawm lub cuab yeej yog muab los ntawm qhov hluav taws xob thiab tam sim no ntawm S theem ntawm lub tshuab hluav taws xob rau kev tshawb pom ib-theem rov qab fais fab.Hauv nws qhov hluav taws xob tsim hluav taws xob, thawj sab ntawm cov hluav taws xob hloov hluav taws xob M1 thiab M2 txuas nrog rau cov hnub qub sib luag, thiab qhov hluav taws xob Uso' raug coj tawm raws li lub teeb liab voltage.Thiab ua Uso' nyob rau theem nrog rau theem voltage USO tso zis los ntawm lub tshuab hluav taws xob.Nws cov teeb liab tam sim no tau txais los ntawm S-theem tam sim no transformer thiab kho los ntawm ob-theem choj rectifier circuits VD1 thiab VD2.Nyob rau hauv voltage U1 ntawm resistor R3, qhov voltage U2 ntawm resistor R4 thiab lub hwj chim nrhiav kom tau txuas, tus nqi kiag li kev sib piv txoj cai yuav tsum tau siv rau kev tshawb nrhiav.Thaum R1 = R2, DC tswj lub teeb liab voltage UNM tso zis los ntawm lub zog nrhiav kom tau txuas ncaj qha rau lub zog nquag P thiab cuam tshuam cov kev taw qhia ntawm P. Hauv kev rov qab fais fab, DC tswj teeb liab voltage UNM yog qhov tsis zoo, uas yog, N. -point peev xwm siab tshaj qhov m-point peev xwm.Thaum lub hwj chim rov qab mus txog 8% ntawm lub zog ntsuas ntawm lub tshuab hluav taws xob, lub triode VT1 yog nyob rau thiab VT2 tawm.Lub zog ua hauj lwm them nqi capacitor C los ntawm cov resistors R15 thiab R16, nrog rau kev ncua sij hawm ntawm 5s.Thaum lub charger voltage ntawm capacitor C mus txog qhov tawg voltage ntawm voltage stabilizing raj W1, raj W1 yog qhib, diode VD3 thiab triode VT3 yog qhib, qhov hluav taws xob relay D1 yog powered rau thiab ua, thiab lub hwj chim mov hloov mus txawv tebchaws, yog li ntawd. raws li kev ua tiav lub hom phiaj ntawm kev tiv thaiv.
