Nyob rau hauv lub zaus converter, lub cev muaj zog ceev braking los yog raug nres, feem ntau yog siv zog braking thiab regenerative braking.Rau lub hwj chim braking hom, lub braking torque yuav tsum tau los ntawm lub system yog qis dua 20% ntawm lub rated torque ntawm lub cev muaj zog thiab lub braking tsis ceev, tsis tas yuav tsum tau rau sab nraud braking resistor, thiab tsuas yog lub sab hauv active poob ntawm lub cev muaj zog. ua rau DC sab voltage txwv qis dua tus nqi ntawm kev tiv thaiv tshaj-voltage.Ntawm qhov tsis sib xws, nws yog qhov yuav tsum tau xaiv lub braking resistor kom dissipate ib feem ntawm lub zog regenerated los ntawm lub cev muaj zog.Txhawm rau kom paub qhov hluav taws xob nres, DC sab ntawm lub inverter yuav tsum tau nruab nrog lub ntsuas hluav taws xob ntsuas hluav taws xob txhawm rau txheeb xyuas qhov voltage ntawm lub capacitor txhawm rau kom paub lub zog nres.Braking resistorsyog dav siv nyob rau hauv ntau yam khoom siv hluav taws xob.
Thaum braking nrog lwm tus braking resistor, sab nraud resistor yuav tsum muaj peev xwm nqus tau 80% ntawm cov hluav taws xob hluav taws xob hloov pauv los ntawm lub zog muaj peev xwm, ntawm 20% tuaj yeem noj los ntawm lub cev muaj zog hauv daim ntawv ntawm cov cua sov, lub sijhawm no tus nqi. ntawm lub braking resistor ua me me, seb lub cev muaj zog yog pheej rov decelerated, xaiv ntawmbraking resistorntsuas fais fab sib txawv.Thaum tsis rov ua dua, lub braking resistor ntawm lub sij hawm sib tshuam (T-tS) > 600s.Feem ntau siv lub luag haujlwm txuas ntxiv mus, thaum lub sijhawm sib cuam tshuam, lub zog tiv thaiv kev tso cai yuav ua rau kom cov ntawv thov kev xaiv raug ntawm lub braking unit resistor tuaj yeem ua rau lub sijhawm tsis pub dawb ntawm qhov loj inertia loads kom ua tiav ceev ceev lossis raug nres;kuj tuaj yeem nyob rau hauv lub zog me ntsis loads qis dua kom ua tiav cov haujlwm ua haujlwm.
Qee cov neeg siv khoom 'electrolysis Rhiav multifunctional unit tsim tsis xav txog kev ntxiv inverterbraking resistor, uas ua rau lub sij hawm tsis pub ncua ntev thiab ntev skidding nrug ntawm lub tsheb loj, uas muaj qhov tsis zoo ntawm kev tsim khoom thiab kev ua haujlwm;Nws yog ib qho nyuaj kom paub qhov tseeb qhov chaw ntawm cov cuab yeej trolleys thiab txhuas trolleys, uas cuam tshuam rau kev ua haujlwm zoo.Tom qab lub installation ntawm braking resistors, cov teeb meem saum toj no tau daws.Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias, nyob rau hauv kev xaiv ntawm braking resistor, tsis tsuas yog xav txog qhov yuav tsum tau ntawm txhua qhov chaw tsim tshuaj paus inverter braking resistor xaiv, tab sis kuj raws li tus neeg siv cov kev cai tswj thiab kev siv ntawm ib puag ncig sib txawv, nws yuav tsum yog los ntawm kev ceev. , torque thiab lwm yam kev ntsuas, thiab tom qab ntawd xam qhov tseeb xaiv ntawm braking resistor, thiaj li ua tau raws li tus neeg siv cov kev cai tswj.
