Yuav xaiv cov khoom tiv thaiv hluav taws xob tiv thaiv SPD chaw tsim tshuaj paus
8 lub ntsiab lus tseem ceeb ntawm kev yuav khoom pluggable surge tiv thaiv cov khoom siv los ntawm Tuam Tshoj
Peb LSP ib lub chaw tsim khoom hauv Tuam Tshoj txij xyoo 2010, tsom rau peb lub zog ntawm kev txhim kho kev tiv thaiv kev tiv thaiv thiab ntawm kev tsim hluav taws xob AC DC PV txheej tiv thaiv cov cuab yeej, mob siab ua haujlwm rau peb cov neeg siv khoom zoo.
Yog tias koj yog cov khoom siv hluav taws xob ua hluav taws xob, tus neeg sawv cev, cov xa khoom, cov chaw muag khoom lossis cov chaw muag khoom, thaum koj yuav AC thiab DC lossis PV SPDs (cov khoom siv tiv thaiv hluav taws xob), koj yuav tsum paub 8 lub ntsiab lus tseem ceeb ntawm kev yuav khoom hloov chaw hloov tiv thaiv cov khoom tiv thaiv (SPD) los ntawm Tuam Tshoj
1. Cov khoom siv raw
(1.1) Hlau Oxide Varistor - MOV
Raws li lub hauv paus tseem ceeb ntawm sab hauv SPDs, tsis tas yuav hais, SPD zoo feem ntau yog nyob ntawm varistors zoo. Pom zoo siv cov MOV tau txais qhov tseem ceeb dua, muaj ntau lub npe nrov ntawm cov hlau oxide varistors rau xaiv xws li EPCOS / TDK, Littelfuse, Keko, Varsi…

Tom qab xaiv cov hlau oxide varistor (MOV), peb tseem yuav tsum them nqi rau yuav ua li cas muab nws tso rau hauv SPD vaj tse. muaj ob txoj kev:
A. rwb thaiv tsev coated varistor, feem ntau yog coated nrog ntsuab lossis xiav xim rau ya raws-pov thawj.
B. Qee lub chaw tsim khoom SPDs siv liab qab varistor nrog contactor, nws xav tau siv epoxy cob rau kev cog lus. Xav paub txog epoxy resin tsis yog kev tiv thaiv ib puag ncig, muaj koob npe hom SPDs tsis txhob ua li ntawd ib zaug ntxiv.
C. Txo txo tus nqi, qee qhov chaw tsim khoom SPDs siv me me varistor hloov 34S varistor, cia peb ua ib qho piv txwv, yog tias koj xav yuav SPDs zoo, cia siab rau nominal tawm tam sim no (8 / 20μs) Hauv = 20kA thiab Qhov siab tso tawm tam sim no (8 / 20μs) Imax = 40kA, nws yuav tsum siv 34S varistor (34 txhais tau tias 34 hli; “S” txhais tau hais tias square), tab sis lawv siv cov varistor me me xws li 20D, 25D, 32D los hloov 34S.

(1.3) Tus qauv tsim sab hauv
Ntau hom tshuaj SPD nyob rau hauv kev ua lag luam, koj yuav pom muaj yog ob qho tseem ceeb sab hauv tus qauv tsim hauv pluggable modular: Dehn style thiab OBO style
OBO cov style:
thaum loj loj tam sim no tuaj, qhov dav ntawm kev sib txuas hlau yog nqaim heev, tsis tuaj yeem tiv taus 40kA surge tam sim no.
Qhov style:
Ua tsaug rau kev tsim qauv tsim nyog, nws tuaj yeem tiv dhau Imax = 40kA kab tam sim no.
(1.4) Tsev nyob yas
cov khoom zoo yog PA66 lossis nylon rau kev tiv thaiv hluav taws.
(1.5) Cov khoom siv hlau, cov khoom siv hlau tseem ceeb yuav tsum yog hlau, tsis yog hlau.
OBO cov qauv siv steel ntu:
Dehn style siv cooper hlau qhov chaw:
(1.6) Kev tiv thaiv ib puag ncig cov khoom siv
Qee lub Hoobkas siv epoxy resin ua kom ntim. Epoxy resin yuv ntxhiab thiab tsis zoo rau kev tiv thaiv ib puag ncig thiab kev noj qab haus huv.
Peb siv cov nplaim hluav taws xob coated varistor, tsis xav tau epoxy resin, nws zoo dua rau kev tiv thaiv ib puag ncig.
2. Kev siv tshuab ntau lawm
Cov khoom siv hlau txuas nrog MOV (varistor) yuav tsum vuam kev ntseeg tau. yog tias kev tuav vuam, nws yooj yim tshwm sim tsis txaus solder. Yog li tsis siv neeg vuam yuav tuaj yeem ua cov khoom kom zoo. https://www.youtube.com/watch?v=RHwNJv8hobE
