OBO vs Leikexing Surge Protective Devices: 2025 Kev Sib Piv Hauv Kev Lag Luam

Kuv tseem nco qab lub sijhawm uas muaj hluav taws xob 40 kA kub hnyiab ib lub txee tswj hwm peb lub xyoo tas los. Qhov ua tsis tau ntawd tau thawb peb kom khiav qhov kev ntsuam xyuas tag nrho, sib npaug ntawm OBO thiab Leikexing SPDs nyob rau hauv cov xwm txheej tswj hwm hluav taws xob.

Xyoo 2025, OBO tseem yog tus qauv rau cov chaw lag luam hnyav, thaum Leikexing muab kwv yees li 90% ntawm kev tiv thaiv ntawm kwv yees li 60% ntawm tus nqi. Kuv tswj hwm lub chaw 2,000 m² hauv Wenzhou thiab muab ob hom, yog li cov ntaub ntawv hauv qab no los ntawm kev teeb tsa tiag tiag - tsis yog cov ntawv tshaj tawm kev lag luam.

Yog tias koj yog tus neeg yuav khoom engineering uas xav tau kev ua tau zoo, TCO, cov kab nkhaus surge, thiab cov ntaub ntawv kev ntseeg siab mus sij hawm ntev ua ntej kos npe rau PO, tsab xov xwm no muab qhov ntawd rau koj.

 Vim li cas Cov SPDs OBO Qib Siab hauv Cov Tshuab Fais Fab Kev Lag Luam

Ob peb xyoos dhau los, muaj xob laim 50 kA ntaus ib tug ntawm peb cov neeg siv khoom hauv Tebchaws Europe. Lawv cov chav OBO tau nqus cov kev nce siab thiab cov kab ntau lawm yeej tsis tau nres. Qhov xwm txheej ntawd qhia tau tias vim li cas OBO tseem yog qhov kev xaiv zoo tshaj plaws hauv kev siv hauv kev lag luam uas muaj kev cuam tshuam.

Txij li xyoo 2018 los, kuv tau teeb tsa ntau dua 3,000 lub OBO Hom 1 thiab Hom 2. Lawv yeej ib txwm dhau qhov kev xeem 25 kA 10/350 µs nrog qhov tso zis tsawg dua 0.9 kV ntawm 400 V systems—kev ua tau zoo uas tseem ceeb thaum lub sijhawm tsis ua haujlwm tuaj yeem raug nqi ntau txhiab daus las ib teev.

 Sab hauv ntawm OBO Design

OBO lub varistor cage uas tau teeb tsa ua ke ua kom muaj kev sib koom tam sim no thiab tiv thaiv txhua lub disk kom tsis txhob tshaj 70% ntawm qhov hnyav. Lub tshuab thermal fuse txiav tawm huv si ntawm ib puag ncig 140 ° C. Tom qab tshuaj xyuas 50 lub units rov qab, tsuas yog peb lub qhia txog qhov tsis zoo me me - pov thawj ntawm kev ruaj khov thermal ntev.

 Peb Yuav Ua Li Cas Txheeb Xyuas OBO Hauv Peb Lub Chaw Kuaj Mob

Txhua pawg khoom uas tuaj txog raug sim nrog lub zog 15 kA 8/20 µs siv peb lub tshuab hluav taws xob Marx 200 kA. Peb saib xyuas qhov clamp voltage drift thiab leakage. 200 units kawg qhia tau tias:

1. Qhov sib txawv ntawm clamp: ≤ 0.3%

2. Kev xau dej:

Qib kev sib xws ntawd sib haum nrog OBO cov kab kos uas tau luam tawm.

 Tus Nqi Tseeb ntawm Kev Muaj Tswv (10-Xyoo TCO)

Nov yog qhov kev faib tawm yooj yim ntawm 10 xyoo tus nqi uas peb siv rau cov neeg siv khoom:

OBO yeej thaum muaj cov nyiaj rov qab los ntawm kev pov hwm. Yog tsis muaj cov nyiaj rov qab, Leikexing yuav zoo nkauj dua.

 Cov yam ntxwv tseem ceeb ntawm OB Hom 1 & Hom 2 SPDs

Lub Xya Hli tas los no, muaj ib qho hluav taws xob 12 kV uas nce mus rau hauv av ntaus peb lub tshuab hluav taws xob loj. Lub OBO Type 1 SPD tau nqus nws tam sim ntawd, thiab peb lub PLC yeej tsis poob qhov sib dhos.

OBO Hom 1 kov 25 kA 10/350 µs, thaum Hom 2 txhawb nqa 100kA 8/20µsOb qho tib si sib koom ua ke qhov dav ntawm lub module thiab suav nrog kev xa xov ntawm chaw taws teeb - muaj txiaj ntsig zoo rau kev koom ua ke nrog PLC saib xyuas cov kab ke.

Rhuav Tshem Hom 1 Block

Lub 40 hli varistor disk yog kwv yees li 34% tuab dua li ntawm T2 unit. Ntau thermal mass txhais tau tias:

1. Kub nce qis dua (≈ 8 ° C qhov sib txawv)

2. Kev laus qeeb qeeb nyob rau hauv kev rov ua dua

3. Kev ruaj khov zoo dua hauv cov chaw uas muaj kev hloov pauv transients

 Cov Lus Qhia Tseem Ceeb ntawm Hom 2 Chav

Lub OBO Hom 2 SPD raug ntsuas 100 kA, tab sis tau ntawv pov thawj rau tsuas yog 20 lub zog nce siabntawm theem ntawd. Cov chaw uas muaj zaus micro-surge siab (piv txwv li, cov chaw khaws ntaub ntawv) yuav tsum siv:

1. Ob lub T2 units ua ke

2. Kev sib hloov txhua xyoo rau kev hnav txawm tias

 Leikexing SPDs rau AC & PV Daim Ntawv Thov

Kuv tau tsim Leikexing hauv xyoo 2015 vim tias cov hom lag luam SPD loj tsis kam muab cov xaj me me ntawm PV. Niaj hnub no peb xa ntau dua 80,000 units txhua xyoo thoob ntiaj teb.

Peb cov kab AC tes tuav 20 kA 10/350 µs, thiab peb cov kab PV npog 40 kA 8/20 µsnrog rau kev xaiv voltage ntawm 275 V, 600 V, thiab 1,000 V. Txhua pawg ntau lawm dhau los ua 48-teev laus ntawm 85 ° C thiab ua raws li IEC 61643-11 thiab ISO 9001.

 Sab Hauv Peb Daim Ntawv Qhia Txog Varistor

Peb tau txais 32 hli MOV disks los ntawm cov chaw tsim khoom saum toj kawg nkaus uas tau koom nrog cov npe loj hauv EU. Peb cov ntawv luam tawm peb txheej nyiaj ua kom txo qhov hluav taws xob tua hluav taws los ntawm kwv yees li 12Vthiab ua kom nruj dua qhov clamp kam rau siab. Thoob plaws 1,000 lub disks peb ntsuas:

1. Kev sib kis ntawm lub zog hluav taws xob: ±4V

2. Ib nrab ntawm qhov sib txawv uas pom hauv peb cov txheej txheem xyoo 2020

 Cov Lus Qhia Txog PV String SPD

Cov PV arrays ntab ib ncig ntawm ±800 V, thiab qhov yuam kev hauv av tuaj yeem tsa ob lub ncej mus rau 1,100 V. Peb lub Y2 capacitor built-in ua kom ob lub ncej ruaj khov thiab ua kom lub zog varistor qis dua 900 V. Hauv kev sim ru tsev 150 kW nrog 6 kV impulses:

1. Rov pib dua Inverter: 0

2. Lub npe ua ntej ntawm tib lub xaib: 23 qhov rov pib dua ib lub caij cua daj cua dub

Dab tsi Losnyob rau hauv lub thawv

1. Lub hauv paus DIN-rail

2.Plug-in module nrog xim qhia

3.6 mm² L/N tawb clamps

4.16 mm² PE tawb clamp

5. QR code txuas rau daim ntawv qhia kev xeem ua pawg

6. Daim ntawv pov thawj hloov pauv tsib xyoos

Daim voucher uas pom tseeb hauv lub thawv pab txo cov kev txhawj xeeb ntawm cov neeg siv khoom thiab txo qhov kev sib txhuam ntawm kev thov.

Kev Sib Piv Txog Kev Siv Tshuab: OBO vs Leikexing SPD

Peb tau teeb tsa ob lub SPDs rau ntawm tib lub DIN rail thiab muab lawv tso rau tib lub surge pulses. Hauv qab 20 kA 10/350 µs kev sim:

1.OB clamp:0.9 kV

2.Leikexing clamp:1.05 kV

Ob leeg tau dhau qhov yuav tsum tau ua kom muaj kev tiv taus kub thiab nce siab. OBO muab kev xa xov hluav taws xob deb, thaum Leikexing muab lub tshuab rov teeb tsa dua thiab tus nqi qis dua.

 Cov Txiaj Ntsig ntawm Kev Ntsuas Surge Ib Sab

Hauv qab no yog cov ntaub ntawv sim ib sab los ntawm peb cov kev sim tswj hwm hluav taws xob:

Qhov sib txawv (≈150 V) tseem ceeb rau cov khoom thauj uas rhiab heev xws li SMPS-tsav cov khoom siv hluav taws xob.

 Kev Ntsuas Kub Kub

Hauv qhov cub 70 ° C ntawm 1.3 Uc rau plaub teev:

1. OBO thermal fuse qhib thaum ≈142 °C

2. Lub tshuab hluav taws xob Leikexing qhib thaum ≈138 °C

Leikexing lub breaker tuaj yeem pib dua, uas pab nyob rau hauv kev sib txuas lus deb lossis sab nraum zoov.

 Kev Taw Qhia thiab Kev Sib Xws

1. Ob leeg yog 4-module units

2. Cov qhov sib dhos sib dhos tsis pub dhau 0.5 hli

3. Hloov tau ncaj qha rau hauv

Peb tau sim qhov kev sib pauv nyob rau ntawm ib qho chaw hauv Is Nrias teb; qhov kev hloov pauv tsuas yog siv sijhawm xya feeb xwb.

 Kev Sib Piv Tus Nqi & Tus Nqi rau xyoo 2025

Tsis ntev los no, ib tug neeg siv khoom hauv Tebchaws Meskas tau thov kom muaj TCO rau ib qhov project 500-panel. Cov lej no tau txhawb nqa Leikexing heev.

Xyoo 2025:

1.OB:$98 FOB

2.Leikexing:$58 FOB

Tom qab them se thiab khoom thauj, tus nqi tsaws hauv Tebchaws Meskas yog $ 123.7 piv rau $ 73.7.

Cov Lus Qhia Txog Tus Nqi Tag Nrho Rau Kev Tso Cai

Nov yog qhov kev sib piv tag nrho ntawm tus nqi tsaws raws li qhov xwm txheej ib txwm muaj ntawm Asmeskas cov khoom xa tuaj:

OBO yeej yog tias muaj cov nyiaj rov qab los ntawm kev pov hwm. Yog tsis muaj, Leikexing pheej yig dua thaum xub thawj.

Kev Txo Nqi Rau Kev Txiav Txim Ntau

Leikexing:

1.1–499 daim: daim ntawv teev npe

2,500–1,999 daim: –8%

3.2,000+ daim: –12%

Feem ntau cov EPCs thoob ntiaj teb poob rau hauv qib nruab nrab lossis qib siab.

 Tus nqi ntawm kev xa khoom qeeb

1. Lub sijhawm ua khoom ntawm OBO: 3–4 lub lis piam

2. Leikexing npaj txhij lawm: 20,000 daim

Rau cov haujlwm hnub ci lossis kev tsim kho uas txav mus sai, kev muaj peev xwm txuag tau ntau txhiab daus las hauv cov nqi nplua.

 Xaiv Hom SPD Zoo

Ua ntej koj xaiv, nug koj tus kheej:

1. Lub sijhawm tsis ua haujlwm raug nqi dab tsi?

2. Koj lub tuam txhab pov hwm puas muab cov nyiaj rov qab ntsig txog SPD?

3. Koj puas xav tau kev saib xyuas deb?

4. Qhov ceev ntawm kev xa khoom puas tseem ceeb?

Ob qho tib si OBO thiab Leikexing ua raws li cov qauv SPD thoob ntiaj teb. Feem ntau qhov kev xaiv yog nyob ntawm qhov kev pheej hmoo ntawm qhov project, kev xav tau kev saib xyuas, thiab kev siv nyiaj txiag.

Tsob Ntoo Txiav Txim Siab Ib Feeb

• Xav tau qhov xwm txheej PLC nyob deb? → OBO
• Cov nyiaj rov qab los ntawm kev pov hwm ≥15%? → OBO
• Nyiaj txiag tsis txaus, lub sijhawm tsis ua haujlwm Leikexing
• Xav tau kev xa khoom tsawg dua 10 hnub? → Leikexing
• Qhov kub ntawm qhov chaw > 60 °C? → OBO
