Puas Yog Qhov Txawv Ntawm Hom 1 + 2 thiab Hom 2 Surge Protection Devices?

Nkag siab txog Hom 1 + 2 tiv thaiv kev kub ntxhov vs Hom 2 kev sib txawv yog qhov tseem ceeb thaum tsim qauv kev ua haujlwm zoo lub zog tiv thaiv hluav taws xobCov khoom siv tiv thaiv hluav taws xob ntau hom (SPD) yog tsim los tswj cov xwm txheej hluav taws xob tshwj xeeb, tshwj xeeb yog cov hluav taws xob xob laim thiab cov hluav taws xob hloov pauv.

Hauv cov chaw faib hluav taws xob niaj hnub no, cov engineers feem ntau xa ib qho Ua ke Hom 1 + 2 SPD ntawm qhov rooj nkag kev pabcuam kom tiv thaiv cov hluav taws xob muaj zog heev, thaum Hom 2 cov khoom siv tiv thaiv kev kub ntxhov feem ntau ntsia rau hauv cov vaj huam sib luag faib khoom downstream.

Cov chaw ua lag luam, cov tsev lag luam, thiab cov tshuab hluav taws xob rov ua dua tshiab feem ntau koom ua ke ob hom khoom siv ua ib feem ntawm cascading surge protection system kom ntseeg tau tias muaj kev tiv thaiv sib koom tes thoob plaws lub network hluav taws xob.

Piv txwv ntawm cov kev daws teeb meem tiv thaiv hluav taws xob siab tuaj yeem pom hauv Hom 1 + 2 kev tiv thaiv kev tiv thaiv hluav taws xob siv rau kev teeb tsa nkag kev pabcuam.

Cov SPDs Ua Ke Hom 1 + 2 Yuav Ua Li Cas Tswj Tau Cov Xob laim thiab Cov Hluav Taws Xob Hloov Pauv?

Ib Ua ke Hom 1 + 2 SPD ua ke ob txoj haujlwm tiv thaiv rau hauv ib lub cuab yeej:

• muaj peev xwm tso tawm hluav taws xob tam sim no (Hom 1)

• kev txwv overvoltage los ntawm kev hloov pauv surges (Hom 2)

Qhov kev sib xyaw ua ke no tso cai rau lub cuab yeej ua haujlwm ua ib qho lub cuab yeej tiv thaiv xob laim muaj peev xwm coj tau cov hluav taws xob loj loj uas tshwm sim los ntawm xob laim ncaj qha lossis ze ntawm.

Kev Tiv Thaiv Tam Sim No Xob laim

Thaum muaj kev kub ntxhov loj, ib qho kev lub tshuab ntes hluav taws xob tam sim no yuav tsum tswj cov impulse currents uas tau txhais los ntawm 10/350 μs waveform test siv rau hauv IEC 61643-11 lub cuab yeej tiv thaiv kev kub ntxhov cov qauv.

Hom 1 + 2 SPDs tuaj yeem tso tawm cov hluav taws xob muaj zog no yam tsis ua rau cov khoom siv hauv qab puas tsuaj.

Kev Tiv Thaiv Surge Switching

Cov kev hloov pauv surges yog los ntawm:

• kev hloov pauv transformer

• cov xwm txheej pib/nres lub cev muaj zog

• kev hloov pauv ntawm lub txhab nyiaj capacitor

• kev cuam tshuam ntawm lub grid

Qhov theem tiv thaiv Hom 2 uas sib xyaw ua ke txwv tsis pub muaj qhov hluav taws xob seem, ua kom cov khoom siv rhiab heev tau txais hluav taws xob ruaj khov.

Vim li no, ntau yam niaj hnub no cov khoom siv tiv thaiv kev kub ntxhov hauv kev lag luam ua ke xob laim thiab kev tiv thaiv hluav taws xob hauv ib lub module.

Cov Hom 1 + 2 thiab Hom 2 SPDs Tau Nruab Rau Hauv Cov Tshuab Fais Fab Nyob Qhov Twg?

Qhov chaw SPD kom raug yog txiav txim siab los ntawm LPZ thaj chaw tiv thaiv xob laim lub tswv yim siv rau hauv kev tiv thaiv kev kub ntxhov.

Txhua cheeb tsam sawv cev rau qib sib txawv ntawm kev raug xob laim.

Hom 1 + 2 SPD Kev Teeb tsa

Ib Hom 1 + 2 tiv thaiv kev kub ntxhov feem ntau yog ntsia rau ntawm:

• qhov rooj nkag mus rau kev pabcuam hauv tsev

• pawg thawj coj faib khoom tseem ceeb

• cov vaj huam sib luag nkag mus rau hauv lub tshuab hluav taws xob

• Cov vaj huam sib luag photovoltaic AC combiner

Cov khoom siv no muab kev tiv thaiv hluav taws xob ntawm lub rooj tsavxwm faib khoom loj tawm tsam cov xob laim muaj zog heev nkag mus rau hauv lub cev hluav taws xob.

Hom 2 SPD Kev Teeb tsa

Ib Hom 2 tiv thaiv kev kub ntxhov feem ntau yog ntsia:

• ntawm cov pawg faib khoom me me

• cov khoom siv sab hauv vaj huam sib luag

• nyob ze ntawm cov khoom siv hluav taws xob rhiab heev

Cov khoom siv no feem ntau siv ua DIN rail surge protectors mounted sab hauv cov txee tswj lossis cov vaj huam sib luag faib khoom.

Cov Qauv Sib Koom Tes SPD Ib Txwm Muaj

Qhov kev npaj hierarchical no tsim ib qho cascading surge protection system, xyuas kom meej tias lub zog hluav taws xob maj mam txo qis thoob plaws hauv lub network hluav taws xob.

Yuav Xaiv Li Cas Ntawm Hom 1 + 2 thiab Hom 2 Surge Protection Devices?

Xaiv lub cuab yeej zoo hauv Hom 1 + 2 tiv thaiv kev kub ntxhov vs Hom 2 kev sib piv nyob ntawm qhov kev teeb tsa ntawm lub kaw lus thiab kev raug xob laim.

1. Soj Ntsuam Qhov Raug Xob laim

Cov chaw nyob hauv thaj chaw uas muaj xob laim lossis nruab nrog cov tshuab tiv thaiv xob laim sab nraud feem ntau yuav tsum tau Ua ke Hom 1 + 2 SPD cov khoom siv ntawm qhov nkag fais fab.

Cov khoom siv no tswj cov hluav taws xob siab ua ntej cov hluav taws xob nce siab kis mus rau hauv lub cev.

2. Xav txog kev teeb tsa lub kaw lus av

Cov txheej txheem sib txawv ntawm cov av cuam tshuam rau kev xaiv SPD.

Cov kev teeb tsa feem ntau muaj xws li:

• TN-S tiv thaiv kev kub ntxhov

Txhua qhov kev teeb tsa av cuam tshuam rau txoj kev uas cov hluav taws xob ntws mus rau hauv ntiaj teb.

Kev sib koom tes SPD kom zoo ua kom muaj kev ua raws li txoj cai IEC 61643-11 lub cuab yeej tiv thaiv kev kub ntxhov cov cai.

3. Soj Ntsuam Qhov Hluav Taws Xob thiab Qhov Rhiab ntawm Lub Tshuab

Cov khoom siv hluav taws xob rhiab heev xws li:

• Cov tswj PLC

• cov txheej txheem automation hauv kev lag luam

• Cov khoom siv IT

• cov khoom siv sib txuas lus

feem ntau xav tau kev pab los ntawm cov kws tshaj lij Hom 2 cov khoom siv tiv thaiv kev kub ntxhov rau qhov kev txwv voltage meej.

Cov khoom siv no muab kev tiv thaiv ntxiv rau hauv qhov dav dua lub zog tiv thaiv hluav taws xob.

4. Xav txog qhov yooj yim thiab qhov chaw rau kev teeb tsa

Hauv ntau lub tsev niaj hnub no, cov engineers nyiam siv cov khoom siv no. ua ke Hom 1 + 2 SPDs vim tias lawv txo qhov nyuaj ntawm kev teeb tsa los ntawm kev koom ua ke ob theem kev tiv thaiv rau hauv ib lub cuab yeej.

Cov kev daws teeb meem qib kev lag luam tuaj yeem tshawb nrhiav los ntawm cov peev txheej tsim kho kev tiv thaiv hluav taws xob los yog los ntawm kev tiv tauj cov kws tshwj xeeb tiv thaiv kev kub ntxhov ntawm kev sab laj txog kev txawj ntse.

Xaus lus

Nkag siab txog Hom 1 + 2 tiv thaiv kev kub ntxhov vs Hom 2 qhov sib txawv yog qhov tseem ceeb thaum tsim cov tswv yim tiv thaiv kev kub ntxhov txhim khu kev qha.

• Hom 1 + 2 SPDs tiv thaiv cov hluav taws xob muaj zog heev thiab cov hluav taws xob hloov pauv ntawm qhov nkag mus rau kev pabcuam.

• Hom 2 SPDs muab kev tiv thaiv thib ob hauv cov vaj huam sib luag faib khoom thiab cov khoom siv hluav taws xob.

Thaum muab sib xyaw ua ke hauv ib lub architecture sib koom ua ke raws li LPZ thaj chaw tiv thaiv xob laim, cov khoom siv no tsim ib qho kev ua haujlwm zoo cascading surge protection system uas tiv thaiv cov khoom siv hluav taws xob thiab cov khoom siv rhiab heev.
