Dab tsi yog Hom 1 + 2 Surge Protection Device?

Hauv cov khoom siv hluav taws xob niaj hnub no, cov khoom siv no feem ntau raug ntsia rau ntawm qhov nkag mus rau kev pabcuam lossis lub rooj faib khoom loj kom tiv thaiv tag nrho lub zog tiv thaiv hluav taws xob.

Nkag siab txog kev sib raug zoo ntawm Hom 1 + 2 tiv thaiv kev kub ntxhov vs Hom 2 yog qhov tseem ceeb thaum tsim kev tiv thaiv kev sib koom tes hauv kev lag luam thiab kev lag luam fais fab.

Tsis zoo li tus qauv Hom 2 tiv thaiv kev kub ntxhov, uas feem ntau tiv thaiv tiv thaiv xob laim tsis ncaj qha thiab kev hloov pauv surges, ib qho Hom 1 + 2 tiv thaiv kev kub ntxhov tau tsim los tswj cov xob laim muaj zog heev thaum tseem txwv qhov hluav taws xob ntau dhau.

Muaj ntau lub tshuab tiv thaiv kev nkag mus rau hauv kev pabcuam sib koom ua ke DIN rail surge protectors tsim tshwj xeeb rau kev muaj peev xwm tso tawm siab thiab ua raws li IEC 61643-11 lub cuab yeej tiv thaiv kev kub ntxhov cov qauv.

Piv txwv ntawm cov thev naus laus zis tiv thaiv no tuaj yeem pom muaj nyob rau hauv cov chaw tshwj xeeb Hom 1 + 2 SPD kev daws teeb meem tsim los rau cov chaw faib hluav taws xob hauv kev lag luam.

Hom 1 + 2 SPD ua haujlwm li cas ua tus ntes hluav taws xob tam sim no?

Ib Ua ke Hom 1 + 2 SPD ua haujlwm ua ib qho lub tshuab ntes hluav taws xob tam sim no los ntawm kev hloov cov hluav taws xob muaj zog siab los ntawm cov xwm txheej xob laim mus rau lub kaw lus av kom muaj kev nyab xeeb.

Cov khoom siv no yog tsim los kom ua tau raws li tus qauv 10/350 μs xob laim impulse waveform, uas sawv cev rau lub xob laim ncaj qha nkag mus rau hauv lub network hluav taws xob.

Txoj Kev Tawm Hluav Taws Xob Tam Sim No

Thaum muaj hluav taws xob ntau los yog muaj zog heev, lub zog hluav taws xob yuav nce siab zuj zus lub cuab yeej tiv thaiv xob laim ua kom cov khoom tiv thaiv sab hauv ua haujlwm sai sai xws li:

• cov hlau oxide varistors (MOV)

• Cov raj xa roj (GDT)

• cov qauv sib txawv ntawm qhov hluav taws xob

Cov khoom no ua rau lub zog nce mus rau hauv av thaum txwv qhov hluav taws xob mus txog cov voj voog qis.

Hauv cov kab ke tsim raws li LPZ thaj chaw tiv thaiv xob laim, Hom 1 + 2 SPDs feem ntau raug ntsia thaum hloov pauv ntawm LPZ 0 thiab LPZ 1.

Qhov chaw no tiv thaiv cov hluav taws xob siab kom tsis txhob nthuav dav mus rau hauv qhov chaw teeb tsa hluav taws xob.

Rau kev sib piv txog kev siv tshuab kom ntxaws piav qhia Hom 1 + 2 tiv thaiv kev kub ntxhov vs Hom 2, koj tuaj yeem xa mus rau phau ntawv qhia engineering ntawm no:

Cov Ntawv Thov Twg Yuav Tsum Tau Ua Ke Hom 1 + 2 SPDs?

Ib Ua ke Hom 1 + 2 SPD yog siv dav hauv cov tshuab fais fab uas xav tau kev tiv thaiv xob laim thiab kev txwv tsis pub muaj hluav taws xob.

Cov Ntawv Thov Ib Txwm Muaj

Cov kev teeb tsa feem ntau suav nrog:

• cov vaj huam sib luag nkag mus rau hauv cov tsev lag luam

• cov tshuab faib hluav taws xob rau kev lag luam

• cov tshuab fais fab photovoltaic

• cov chaw sib txuas lus

• cov chav khoom siv hauv paus

Cov chaw no xav tau kev ruaj khov kev tiv thaiv hluav taws xob ntawm lub rooj tsavxwm faib khoom loj vim tias cov hluav taws xob nkag los ntawm cov xov hluav taws xob tuaj yeem ua rau cov khoom siv puas tsuaj loj heev.

Cov chaw teeb tsa kev lag luam feem ntau siv ib qho cascading surge protection system, qhov twg ntau hom SPD tau teeb tsa ntawm ntau qib ntawm lub network fais fab.

Cov Qauv Sib Koom Tes SPD Ib Txwm Muaj

Cov qauv no ua kom lub zog nce siab maj mam txo qis thoob plaws lub zog tiv thaiv hluav taws xob, txhim kho kev ntseeg tau ntawm cov khoom siv thiab kev nyab xeeb ua haujlwm.

Yuav Ua Li Cas Xaiv Tus Tiv Thaiv Surge DIN Rail Hom 1 + 2?

Xaiv qhov yog DIN rail tiv thaiv hluav taws xob yuav tsum tau soj ntsuam ob qho tib si cov yam ntxwv ntawm lub tshuab hluav taws xob thiab cov xwm txheej ib puag ncig.

1. Soj ntsuam qhov hluav taws xob ntawm lub cev thiab kev teeb tsa av

Lub SPD yuav tsum phim qhov kev teeb tsa av ntawm lub kaw lus.

Cov kev teeb tsa feem ntau muaj xws li:

• TT tiv thaiv kev kub ntxhov system

• TN-S tiv thaiv kev kub ntxhov

Txhua lub kaw lus yuav tsum muaj cov kev teeb tsa SPD tshwj xeeb kom ntseeg tau tias cov hluav taws xob surge tau raug tso tawm mus rau hauv av kom raug.

2. Tshawb xyuas qhov ntsuas tam sim no ntawm xob laim

Rau ib qho Ua ke Hom 1 + 2 SPD, cov kev ua tau zoo tseem ceeb suav nrog:

• kev ntsuas tam sim no ntawm lub zog (Iimp)

• nominal tawm tam sim no (Hauv)

• qhov siab tshaj plaws tam sim no (Imax)

Yuav tsum muaj peev xwm tam sim no siab dua nyob rau hauv cov cheeb tsam uas muaj xob laim lossis cov chaw teeb tsa uas muaj cov tshuab tiv thaiv xob laim sab nraud.

3. Xyuas kom ua raws li IEC Cov Qauv

Ib qho txhim khu kev qha kev lag luam tiv thaiv kev kub ntxhov yuav tsum ua raws li IEC 61643-11 lub cuab yeej tiv thaiv kev kub ntxhov cov kev cai, uas txhais cov hauv qab no:

• cov qauv ntsuas surge

• kev faib tawm ntawm cov khoom siv

• kev ua tau zoo ntawm kev nyab xeeb

Kev ua raws li txoj cai ua kom muaj kev sib raug zoo nrog cov cai tswjfwm kev nyab xeeb hluav taws xob thoob ntiaj teb.

4. Xav txog qhov chaw teeb tsa thiab kev saib xyuas

Niaj hnub nim no tshaj plaws DIN rail surge protectors yog cov khoom siv modular tsim rau kev teeb tsa hauv cov vaj huam sib luag faib hluav taws xob txheem.

Kev xaiv lub SPD me me tab sis muaj peev xwm siab ua rau kev koom ua ke yooj yim rau hauv cov chaw hloov pauv kev lag luam thiab cov txee tswj hwm.

Cov peev txheej tsim qauv tiv thaiv kev kub ntxhov ntxiv muaj nyob ntawm Leikexing kev tiv thaiv hluav taws xob tiv thaiv kev tsim kho kev daws teeb meem, thaum cov lus nug tshwj xeeb rau qhov project tuaj yeem xa tuaj ntawm kev sab laj txog kev txawj ntse.

Xaus lus

Ib Ua ke Hom 1 + 2 SPD ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv cov khoom siv hluav taws xob tiv thaiv ob qho tib si xob laim thiab kev hloov pauv surges.

Thaum sib piv Hom 1 + 2 tiv thaiv kev kub ntxhov vs Hom 2, qhov sib txawv tseem ceeb yog nyob rau hauv lub peev xwm tswj hluav taws xob tam sim no thiab qhov chaw teeb tsa hauv cov kab ke tiv thaiv kev co.

Los ntawm kev sib koom ua ke Hom 1 + 2 cov khoom siv tiv thaiv kev kub ntxhov rau hauv cov vaj huam sib luag nkag mus rau hauv kev pabcuam thiab sib koom tes nrog cov neeg ua haujlwm hauv qab Hom 2 cov khoom siv tiv thaiv kev kub ntxhov, cov engineers tuaj yeem tsim kom muaj kev ntseeg siab cascading surge protection system uas tiv thaiv cov khoom siv hauv kev lag luam thiab kev teeb tsa hluav taws xob.
