Braking Resistor Box yog ib qho khoom siv hluav taws xob tseem ceeb uas siv rau hauv lub tshuab tsav tsheb thiab kev tswj hwm kev lag luam automation. Nws lub luag haujlwm tseem ceeb yog dissipate regenerative hluav taws xob hluav taws xob tsim tawm thaum lub cev muaj zog decelerates, nres, lossis ua haujlwm nyob rau hauv ib qho overhaling load. Nws hloov hluav taws xob ntau dhau mus rau hauv tshav kub thiab tso tawm mus rau ib puag ncig ib puag ncig, pab tswj kev ua haujlwm ntawm hluav taws xob ib txwm muaj thiab txhim kho kev ua haujlwm braking.
Ua ntej, Braking Resistor Box dissipates regenerative zog generated thaum lub cev muaj zog deceleration. Hauv qee lub tshuab tsav lub cev muaj zog, thaum lub cev muaj zog hloov pauv los ntawm kev ua haujlwm ib txwm mus rau kev ua kom qeeb, nws tuaj yeem nkag mus rau hauv lub xeev tsim thiab hloov ib feem ntawm nws cov tshuab hluav taws xob rau hauv hluav taws xob. Lub zog no tau muab rov qab rau hauv DC tsheb npav ntawm qhov sib txawv zaus tsav. Yog tias lub zog tsis tuaj yeem ploj mus sai, DC lub tsheb npav voltage yuav nce ntxiv. Lub Braking Resistor Box siv lub zog ntau dhau los ntawm lub voj voog nres, pab tswj lub tsheb npav DC nyob rau hauv qhov kev ua haujlwm tsim nyog.
Thib ob, Lub Thawv Nres Nres Resistor pab ua kom tiav cov khoom siv braking. Hauv kev tsim khoom lag luam, ntau lub tshuab yuav tsum pib thiab nres tsis tu ncua lossis decelerate sai raws li qhov yuav tsum tau ua. Kev cia siab ib leeg rau ntawm ntuj deceleration yuav tsis ua raws li qhov xav tau tiag tiag rau kev nrawm nrawm thiab tswj kev txav. Thaum teeb tsa kom raug, lub Braking Resistor Box pab lub zog tsav tswj lub zog rov ua haujlwm zoo dua, tso cai rau cov khoom siv kom qeeb thiab nres raws li kev tswj hwm.
Thib peb, Braking Resistor Box pab tiv thaiv cov tsav tsheb sib txawv thiab cov khoom siv hluav taws xob cuam tshuam. Thaum lub cev muaj zog ua haujlwm nyob rau hauv hom regenerative braking, lub zog hluav taws xob rov qab mus rau hauv lub cev yuav ua rau lub tsheb npav DC voltage siab dhau yog tias nws tsis tuaj yeem cuam tshuam tau zoo. Qhov no yuav ua rau muaj kev tiv thaiv overvoltage thiab cuam tshuam rau kev ua haujlwm ntawm cov khoom siv txuas ntxiv. Los ntawm kev siv hluav taws xob ntau dhau, lub Braking Resistor Box pab txo qhov kev pheej hmoo ntawm cov teeb meem no.
Tsis tas li ntawd, Braking Resistor Boxes tuaj yeem ua tau raws li qhov xav tau ntawm kev sib tsoo ntawm ntau yam kev siv. Hauv cov khoom nqa nqa, lub cev muaj zog yuav tsum tswj kev nce thiab txo qis ntawm cov khoom hnyav. Thaum lub sij hawm load txo, lub load yuav tsav lub cev muaj zog mus rau hauv lub generating lub xeev, ua regenerative zog. Lub Braking Resistor Box pab kom tshem tawm lub zog no. Hauv kev ua haujlwm of the elevator, nws tuaj yeem pab tswj cov khoom siv hluav taws xob tsim hluav taws xob thaum lub tsheb txav mus thiab deceleration. Hauv cov tshuab conveyor thiab cov kab ntau lawm, nws tuaj yeem txhawb nqa lub tshuab tsav tsheb uas yuav tsum tau pib, nres, lossis nrawm nrawm.
Lub Braking Resistor Box tseem tuaj yeem pab txhim kho kev ua haujlwm txuas ntxiv. Hauv cov ntawv thov kev lag luam uas qhov kev tsim khoom tas mus li tseem ceeb, teeb meem xws li DC tsheb npav overvoltage thaum lub sijhawm braking yuav ua rau cov khoom kaw thiab cuam tshuam ntau lawm. Kev siv lub Braking Resistor Box kom zoo pab lub zog tsav tswj lub zog braking zoo dua, txhawb kev ua haujlwm ruaj khov dua.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias Braking Resistor Box yog tsim los rau dissipate regenerative zog. Nws tsis tas hloov cov neeg kho tshuab nres lossis kev ruaj ntseg braking. Cov khoom siv nrog cov neeg ua haujlwm lossis cov khoom hnyav, xws li cranes thiab elevator, tseem yuav tsum tau nruab nrog cov cuab yeej tsim nyog thiab kev tiv thaiv kev nyab xeeb.
Zuag qhia tag nrho, lub hom phiaj tseem ceeb ntawm Braking Resistor Box yog kom tshem tawm lub zog rov ua dua tshiab, pab kev sib tsoo zoo, txo qhov kev pheej hmoo ntawm DC tsheb npav overvoltage, thiab muab kev txhawb nqa braking txhim khu kev qha rau cov tshuab tsav tsheb.
