Nyob rau hauv niaj hnub fais fab system, Circuit Court breakers thiab surge protector yog indispensable tiv thaiv pab kiag li lawm. Txawm li cas los xij, thaum tsim ib qho kev faib khoom lossis xaiv cov khoom siv, ntau tus neeg siv khoom feem ntau nug: nws puas yuav tsum muaj cov khoom tiv thaiv kev tiv thaiv tam sim no uas muaj cov kab hluav taws xob hauv qhov chaw?
Raws li cov kws tshaj lij kev lag luam ntawm surge protector, peb ntseeg tias kev nkag siab qhov sib txawv yog qhov tseem ceeb rau kev txhim kho kev nyab xeeb ntawm cov tshuab hluav taws xob thiab kev ntseeg siab ntawm cov khoom siv.
Dab tsi yog Circuit Breaker?
Circuit Court breakers yog hloov cov cuab yeej siv los tiv thaiv circuits ntawm overload thiab luv luv -circuit tsis ua hauj lwm.
Thaum lub Circuit Court tam sim no tshaj qhov ntsuas tus nqi, lub Circuit Court breaker yuav txiav tawm lub Circuit Court, tiv thaiv cable los ntawm overheating, khoom puas los yog txawm hluav taws.
Circuit Breakers hais txog ob hom teeb meem tseem ceeb:
Overload tam sim no
Short circuit tam sim no
Yog li ntawd, lub luag haujlwm tseem ceeb ntawm Circuit Court breaker yog los tiv thaiv kev nyab xeeb ntawm Circuit Court thiab kev faib tawm.
Dab tsi yog surge protector?
Surge protector (SPD) yog ib qho khoom siv tiv thaiv uas siv los txwv tsis pub dhau lub sijhawm dhau los thiab tso tawm cov dej ntws tawm.
xob laim tawm tsam, hloov daim phiaj hluav taws xob, pib lub cev muaj zog loj, hloov pauv hloov, thiab lwm yam, yuav ua rau lub sijhawm siab siab -voltage mem tes. Txawm hais tias cov voltage surges tsis tshua muaj luv luv nyob rau hauv lub sij hawm, lawv muaj zog txaus kom puas cov khoom siv hluav taws xob sab hauv.
SPD tiv thaiv cov cuab yeej los ntawm overvoltage surges los ntawm ceev ceev cov overvoltage surge tam sim no rau hauv av.
Nws lub hom phiaj tiv thaiv tseem ceeb suav nrog:
PLC tswj qhov system
Server thiab data center khoom siv
Cov khoom siv sib txuas lus hauv paus chaw nres tsheb
Video soj ntsuam systems
Photovoltaic inverter
Industrial automation khoom
Cov khoom siv ntse faib khoom;
Qhov sib txawv tseem ceeb ntawm cov hluav taws xob hluav taws xob thiab hluav taws xob tiv thaiv hluav taws xob:
1. Cov khoom tiv thaiv sib txawv
Kev tiv thaiv Circuit Court breaker:
Kab
Cov kab sib faib
Cov khoom siv hluav taws xob faib khoom
Surge savers feem ntau tiv thaiv:
Precision electronics
Tswj qhov system
Cov khoom siv sib txuas lus
2.Lawv cuam tshuam nrog ntau hom glitches
Kev kho ntawm Circuit Breaker:
Tshaj dhau
Luv luv
Surge saver kev kho mob:
xob laim overvoltage
Ua haujlwm overvoltage
Induced surges
3. Lub sij hawm teb txawv
Lub sij hawm teb ntawm Circuit Court breakers feem ntau yog nyob rau hauv milliseconds.
Surge savers feem ntau teb lub sij hawm hauv nanoseconds.
Vim lub neej luv luv ntawm cov hluav taws xob hluav taws xob, cov hluav taws xob hluav taws xob feem ntau tsis muaj sijhawm txaus los khiav lag luam thiab yog li tsis tuaj yeem hloov SPD tiv thaiv.
4. Cov qauv kev ua haujlwm sib txawv
Circuit Court breaker disconnects Circuit Court los ntawm aa mechanical tripping mechanism.
SPDS (Susceptible Power Distribution Devices) sai sai ua hluav taws xob los ntawm cov khoom xws li inverters thiab gas paug raj, tso tawm hluav taws xob mus rau hauv av.
Vim li cas SPD tseem xav tau txawm tias muaj hluav taws xob hluav taws xob?
Qhov no yog ib qho teeb meem tsis pom zoo hauv ntau qhov haujlwm engineering.
Piv txwv li:
Ib qho hluav taws xob nyob ze tuaj yeem tsim ntau txhiab lossis kaum txhiab tus volts.
Txawm hais tias qhov surge tsuas yog ob peb microseconds, nws txaus los rhuav peb:
PLC input module
Kev sib txuas lus interface
Fais fab mov Module
Tswj lub rooj tsavxwm
Vim lub sijhawm luv luv ntawm tam sim no, Circuit Court breaker tsis tuaj yeem ntes thiab cuam tshuam qhov tsis raug raws sijhawm.
Raws li qhov tshwm sim:
Lub Circuit Court breaker tsis dhia, tab sis cov khoom puas lawm.
Raws li qhov tshwm sim, ntau cov chaw khaws ntaub ntawv, kev lag luam automation systems, photovoltaic fais fab chaw nres tsheb thiab kev sib txuas lus hauv paus chaw nres tsheb tau siv cov khoom siv hluav taws xob-xeev drives raws li cov khoom siv.
Vim li cas lub Circuit Court breaker ua ntej SPD?
Ntau tus neeg siv pom SPD nws tus kheej yog ib qho khoom siv tiv thaiv uas tsis tas yuav muaj kev sib txuas ntxiv.
Qhov tseeb, luv luv Circuit Court tuaj yeem tshwm sim thaum SPD ua tsis tiav vim qhov ntev - kev laus lossis kev cuam tshuam ntau dhau.
Nyob rau lub sijhawm no, nws yog ib qho tsim nyog yuav tsum siv lub tshuab hluav taws xob pem hauv ntej lossis cov cuab yeej tiv thaiv thaub qab los cuam tshuam cov kev ua txhaum tam sim no hauv lub sijhawm los tiv thaiv cov khoom puas thiab kev nyab xeeb kev raug mob.
Yog li ntawd, ib qho kev tiv thaiv kev tiv thaiv tag nrho feem ntau suav nrog:
Daim phiaj → Circuit breaker → SPD → Load khoom
Cov qauv no tiv thaiv overloading thiab luv luv Circuit Court, nrog rau xob laim surges.
Yuav ua li cas xaiv qhov zoo SPD?
Hauv kev xaiv SPD, nws raug pom zoo kom tsom mus rau cov kev txwv hauv qab no:
Qhov siab tshaj plaws kev khiav hauj lwm voltage (Uc)
Nominal tawm tam sim no (hauv nti)
Maximum tawm tam sim no (Imax)
Voltage tiv thaiv theem (saum toj no)
Teb sijhawm
Kev teeb tsa ib puag ncig
Nyob rau tib lub sijhawm, hom 1, hom 2 lossis hom 3 surge protectors yuav tsum raug xaiv raws li qib ntawm kev tiv thaiv xob laim hauv lub tsev thiab cov qauv ntawm kev faib khoom.
Xaus:
Thaum cov hluav taws xob hluav taws xob thiab hluav taws xob tiv thaiv hluav taws xob, lawv lub luag haujlwm sib txawv kiag li. Circuit Court breakers yog lub luag hauj lwm rau kev tiv thaiv overload thiab luv luv -circuit tsis ua hauj lwm, thiab surge protectors yog lub luag hauj lwm rau tiv thaiv xob laim ntaus thiab overvoltages ib ntus. Qhov ob yog complementary thiab indispensable.
Nrog rau txoj kev loj hlob sai ntawm kev lag luam automation, ntse daim phiaj, cov chaw zov me nyuam thiab lub zog tshiab, cov khoom siv hluav taws xob xav tau ntau dua thiab ntau lub zog hluav taws xob zoo thiab kev ruaj ntseg. Kev teeb tsa kom raug ntawm Circuit Court breakers thiab SPD tuaj yeem tsis tsuas yog txhim kho kev ntseeg tau, tab sis kuj txo cov khoom siv tsis ua haujlwm thiab tus nqi kho, thiab tsim kom muaj txiaj ntsig ntev dua - lub sijhawm rau kev lag luam.
