Nyob rau hauv kev tsim khw hauv pem teb, programmable logic controllers thiab sib txawv zaus drives feem ntau zoo li khiav tsis tu ncua. Tsis muaj kev ceeb toom yuam kev tshwm sim, thiab lub zog tawm tswv yim zoo ib yam, tab sis cov cuab yeej no mam li kaw tsis tau ceeb toom. Cov kab uas tsis tau npaj tseg ua rau muaj kev poob nyiaj ntau heev. Cov pab pawg nquag hloov kho vajtse thiab khiav cov kev kuaj xyuas software zoo, tab sis qhov kev ua tsis tiav tsis zoo yuav rov tshwm sim dua. Hauv txhua qhov xwm txheej zoo li no, luv luv voltage dips thiab lub zog tam sim no los ntawm lub zog hluav taws xob hauv zos yog qhov ua rau tiag tiag.

Ib qho hluav taws xob dip txhais tau tias cov khoom siv hluav taws xob poob sai sai rau lub sijhawm luv luv, poob rau 10% mus rau 90% ntawm nws tus qauv tus nqi. Cov kev hloov pauv no tuaj yeem kav ntev li ib nrab ntawm lub voj voog hluav taws xob, nyob ib ncig ntawm 10 milliseconds, lossis ncav cuag ib feeb. Cov hluav taws xob luv luv txiav lub zog ntws yuav luag tag nrho, thiab zoo li tsis tshua muaj sijhawm ntev dua rau caum vib nas this.

Cov xwm txheej niaj hnub no ua rau muaj qhov tsis txaus ntseeg ntawm lub zog no: xob laim nyob ze, pib tam sim ntawm cov tshuab muaj zog loj, tsis siv neeg lub tshuab hluav taws xob rov pib dua tom qab faib cov kab luv luv, thiab arc tawm los ntawm cov khoom siv vuam hnyav ntawm -site. Cov kev cuam tshuam fais fab no nyob ntev heev - nyob, ua rau lawv tsis yooj yim mus ntes. Cov khoom siv tes tuav tsis tu ncua tsis muaj cov lus teb txaus los sau cov spikes thiab tee. Ua-hauv cov ntaub ntawv yuam kev tsuas yog kos cov teeb meem raws li qhov ua tsis tau zoo ntawm cov khoom siv hluav taws xob tsis zoo lossis tsis muaj cov ntaub ntawv tsis ua haujlwm txhua, uas piav qhia vim li cas cov kev kaw no zoo li tsis suav nrog.

PLCs yog qhov yooj yim heev rau cov kev hloov pauv hluav taws xob vim lawv qhov hloov hluav taws xob sab hauv. Cov chav no hloov pauv hloov tam sim no mus rau qhov tsis tshua muaj zog-voltage ncaj qha tam sim no los khiav lub hauv paus ua haujlwm thiab cov tswv yim tawm- cov zis modules, txhawb nqa los ntawm siab - muaj peev xwm sab hauv capacitors uas khaws cia lub zog. Thaum cov khoom siv hluav taws xob poob qis heev, cov capacitors no dhau los ua lub zog hluav taws xob los txhawb kev ua haujlwm ib txwm muaj.
Txawm li cas los xij, lub zog capacitor tsuas yog siv sijhawm li 10 txog 20 milliseconds. Qhov hnyav los yog ntev voltage dips rub capacitor voltage hauv qab qhov chaw ua haujlwm ruaj khov. Cov zis tam sim no ncaj qha txiav tawm tam sim ntawd, PLC tsis ua haujlwm, thiab cov ntaub ntawv ua haujlwm tsis tau khaws cia tau ploj mus tas li. Thaum lub sij hawm daim phiaj fais fab rov qab thiab tus maub los ua tiav nws tus kheej - xyuas kom rov pib dua, cov khoom lag luam twb raug kaw lawm. Lub sijhawm poob qis tsis xav txog qee zaum ua rau tag nrho cov khoom siv tsis tiav uas siv tsis tau.
Variable frequency drives ntsib kev pheej hmoo ua haujlwm zoo ib yam. Lawv cov hluav taws xob hluav taws xob tam sim no nyob hauv lub tsheb npav hloov ze ze nrog cov khoom siv tam sim no. Voltage dips rub lub tsheb npav voltage ceev ceev, ntaus lub preset undervoltage tiv thaiv txwv thiab yuam tus tsav xauv thiab kaw.
Txawm tias muaj kev tsim ua - nyob rau hauv tsis siv neeg restart functions, cov cuab yeej tseem mus los ntawm tag nrho cov fais fab tuag, standby pause thiab ceev pib dua. Cov kev cuam tshuam zoo li no cuam tshuam kev ua haujlwm ntau lawm. Cov tsav tsheb feem ntau tsuas yog khaws cov lej tsis ua haujlwm tshiab kawg nkaus, sau cov teeb meem luv luv ntawm lub zog yooj yim raws li qhov tsis raug ntawm qhov tsis muaj hluav taws xob tsis muaj cov ntaub ntawv ntxaws txog kev cuam tshuam lub sijhawm lossis qhov tshwm sim zaus. Cov neeg ua haujlwm tu neeg ua haujlwm tawm tsam txhawm rau txheeb xyuas qhov tshwm sim thiab feem ntau txiav txim siab tsis ua tiav raws li cov khoom siv tsis ruaj khov.
Sudden shutdowns tsim deb -mus txog kev puas tsuaj ntau lawm. Unplanned nres nres nres cov kab yas extrusion thiab hlawv cov khoom seem hauv cov ntsia hlau. Lub zog luv luv thaum lub sij hawm semiconductor ntim pov tseg tag nrho cov khoom siv wafer. Cov halts luv ntawm cov khoom noj khoom haus ua rau cov khoom noj tsis zoo ua rau lub cev tsis muaj zog thiab xav tau cov kab tua kab mob ntxiv dua. Cov teeb meem me me ntawm hluav taws xob tsis tu ncua sib sau ua ke thiab tsim kev poob nyiaj txiag hnyav hnyav.
Kev cia siab ib leeg rau thawj PLC thiab VFD los tiv thaiv- cuam tshuam kev ua haujlwm tsis tuaj yeem daws qhov teeb meem zoo. Cov txheej txheem kev lag luam tsis ua raws li cov txheej txheem nruj voltage dip tsis kam teeb tsa rau siab -kawg semiconductor manufacturing khoom xws li SEMI F47 qauv. Txhim kho qhov loj - teev cov khoom siv hluav taws xob tsis cuam tshuam rau tag nrho cov kab ntau lawm muaj kev tiv thaiv kev ruaj ntseg tseem yuav tsum tau siv nyiaj ntau, qhov chaw teeb tsa loj thiab cov nqi tu txhua hnub. Qhov kev daws teeb meem no ua pov thawj ua tsis tau zoo, tshwj xeeb tshaj yog rau siab - lub zog sib txawv ntawm lub zog tsav tsheb txij li kaum rau ntau pua kilowatts. Targeted tswj Circuit Court tiv thaiv ua hauj lwm raws li ib tug ntau yig thiab tswv yim lwm txoj.
Peb pom zoo kom txhim kho kev txawj ntse relay tiv thaiv modules tsim los tiv thaiv qhov hluav taws xob poob cuam tshuam. Ua ke nrog compact supercapacitor lub zog cia sib dhos, qhov teeb tsa no tsuas yog muab lub zog ruaj khov rau PLC tswj cov laug cam, VFD tswj cov tshuab thiab cov ntsiab lus tseem ceeb.
Lub module khaws lub sijhawm tiag tiag - saib ntawm cov kab hluav taws xob tuaj. Thaum qhov hluav taws xob poob los yog lub sijhawm tsaus ntuj tshwm sim, nws hloov mus rau lub zog sab hauv standby hauv ib millisecond thiab tswj cov zis ncaj qha tam sim no rau cov khoom tswj. Lub zog hluav taws xob tseem ceeb tuaj yeem poob mus rau qib qis heev, thaum PLCs thiab VFD tswj vaj huam sib luag nyob twj ywm rau ib txwm. Tsis muaj lub tswb yuam kev yuam kev qhib, thiab cov contactors tseem ceeb tseem raug kaw. Cov khoom siv rov ua haujlwm tsis tu ncua seamlessly thaum daim phiaj hluav taws xob rov qab tsis muaj kev tawm tswv yim txawv txav.
Cov ntaub ntawv thov teb tau sau los ntawm lub hwj chim- thaj chaw tsis ruaj khov suav nrog Cov Neeg Esxias Qab Teb Hnub Tuaj thiab Middle East tshawb xyuas qhov kev tiv thaiv kev teeb tsa no txo cov xwm txheej tsis raug kaw ntau dua 90%. Tag nrho cov txheej txheem kev teeb tsa nyob twj ywm yooj yim thiab tsuas yog xav tau kev sib txuas ncaj qha nrog cov tswj fais fab uas twb muaj lawm.
Yog tias koj lub chaw ua haujlwm raug kev txom nyem ntau yam khoom siv tsis tau piav qhia, tsom mus rau kev tshuaj xyuas ntawm - qhov chaw hloov pauv voltage. Millisecond- qib hloov pauv hloov pauv nyob tom qab feem ntau tsis yooj yim kaw teeb meem. Hloov chaw rov sim dua thiab hloov cov tswj hwm thiab cov tsav tsheb, txhim kho qhov tseem ceeb tswj loops nrog cov tswv yim tiv thaiv cov iav. Kev tiv thaiv hluav taws xob hloov pauv tau zoo ua kom cov kab ntau lawm ua haujlwm zoo yam tsis muaj kev cuam tshuam los ntawm kev hloov pauv tam sim no.
