Kev Ua Ntej Tiv Thaiv Kev Tiv Thaiv (SPD)
Feem ntau, tib neeg them nyiaj ntau rau kev ua haujlwm ntawm kev tiv thaiv kev tiv thaiv kev qoj ib ce (SPD) zoo li nws lub peev xwm loj. Kev muaj peev xwm sawv yog qhov tseem ceeb heev. Muaj ntau dhau ntawm cov khoom siv thaiv kev tiv thaiv (SPDs) ntawm kev ua lag luam tsis tuaj yeem ua tau raws li qhov muaj peev xwm tshaj qhov nws tau tshaj tawm. Ntawm no yog daim duab thiab yeeb yaj kiab ntawm SPD uas tau tawg rau ntawm qhov kev ntsuam xyuas tam sim no (Imax 40kA):
Kev Nyab Xeeb ntawm Kev Tiv Thaiv Kev Tiv Thaiv Kab Mob (SPD)
Txawm li cas los xij kev them nyiaj tsawg yog them rau kev nyab xeeb ntawm kev tiv thaiv ib qho khoom tiv thaiv tawm. Txawm li cas los xij, kev tsim qauv tsis zoo SPD tuaj yeem tsim kev phom sij heev thiab yog ib qho ua rau muaj kev phom sij rau hluav taws. Hauv qab no yog qee qhov hlawv SPD cov duab:
SPD / MOV yog Tus Neeg Teebmeem ntawm Kev Tshaj Tawm Ntau Ntu (TOV)
SPDs tsis tsim lossis tsis siv thiab tsis muaj kev tiv thaiv MOVs mus rau hauv thermal runaway, ua rau luv luv, ntxhiab, pa taws thiab muaj teeb meem hluav taws vim yog:
- Kawg ntawm lub neej
- Muaj kev tsis txaus siab dhau los / Kev Tiv Thaiv Ib Ntus (TOV)
- Npau taws nrog kev npaj txhij txog zog
MOV los yog SPD yog cov tiv thaiv ntawm Transient Overvoltage (los yog ntuag), tab sis cov neeg raug tsim txom cov haujlwm dhau ib ntus.
MOV hlawv hauv qab Overvoltage (TOV)
MOV hlawv hauv qab Overvoltage (TOV)
Temporary Overvoltage VS Transitive Overvoltage
Temporary Overvoltage (TOV) | Transient Overvoltage | |
| Ua rau los ntawm | LV / HV-system kev ua yuam kev | xob laim los sis hloov overvoltage |
| Duration | ntev millisecond mus rau ob peb feeb lossis sijhawm | luv luv Microseconds (xob laim) los yog millisecond (switching) |
| MOV xwm txheej | Thermal khiav tawm | Kev rov qab kho yus tus kheej |
TOV yog ntau dua rau SPD vim nws lub sijhawm ntev npaum li cas
Temporary Overvoltage yog ib qho
TOV yog ib qho teeb meem tshwm sim hauv kev siv hluav taws xob zoo
Kev Tiv Thaiv Kev Nyab Xeeb Ntaus Khoom Siv Kev Nyab Xeeb - TPAE Technology
Prosurge tau tsim TPAE (Thermally Tiv Thaiv Arc Tsho Tawm Tshuab) los daws cov teeb meem kev nyab xeeb ntawm SPD thiab peb tau txais cov thev naus laus zis tau txais kev pom zoo hauv Asmeskas, Lub Tebchaws Yelemees, Kauslim thiab Suav.
Patent nyob rau teb chaws USA
Patent nyob rau hauv lub teb chaws Yelemees
Patent nyob rau hauv Kauslim Teb
Patent nyob rau hauv Suav teb
Raws li TPAE thev naus laus zis, peb tau tsim peb qhov tseem ceeb SPD tivthaiv - SMTMOV thiab PTMOV.
SMTMOV
PTMOV
Koj tuaj yeem pom yuav ua li cas peb cov khoom ua kev nyab xeeb nyob rau hauv kev tiv thaiv overvoltage situtation thaum peb tus neeg sib tw cov khoom lag luam hlawv.
Nyob rau ntawm 415Vac ib ntus, peb cov SMTMOV nrog TAPE technology txiav tawm ntawm qhov kev txawv txav no
Thaum 415Vac ib ntus dhau caij nyoog, SPD tivthaiv tsis muaj TPAE technology hlawv.
Hauv kev sim hauv qab no, ob qho tshuaj tiv thaiv SPD tau kuaj raws li TOV (qhov hloov pauv overvoltage). Saib seb qhov txiaj ntsig sib txawv li cas rau SPD nrog TPAE tiv thaiv thiab SPD tsis muaj TPAE tiv thaiv:
Nrog Prosurge patented TPAE technology, SPD yog qhov tsis zoo thiab muaj kev tiv thaiv tus kheej.
Yog tsis muaj arc extinguished khoom, SPD ua pa taws thiab hluav taws, uas yuav ua teeb meem rau hauv Circuit Court.
