SCB series thaub qab tiv thaiv rau SPD
SCB series thaub qab tiv thaiv rau SPD
Cov fuses lossis Circuit Court breakers tam sim no siv ntau nrog SPD tsis sib xws nrog peb cov ntsiab lus hauv qab no
1. Thaum xob laim tam sim no tawg, nws tawg los ntawm kev ua yuam kev thiab yooj yim puas-SPD tsis tuaj yeem ua haujlwm ntawm kev tiv thaiv xob laim;
2. Thaum SPD yog luv luv, lub zog zaus yuav tsis cuam tshuam. Thaum SPD ua tsis tiav lossis cov kab tam sim no tsis loj thaum lub caij luv luv tshwm sim, nws nyuaj rau ua kom tau raws li qhov yuav tsum tau ua tam sim no ntawm lub fuse thiab Circuit Court breaker. Ua rau hluav taws kub;
3. Thaum xob laim tam sim no tawm tsam, qhov seem hluav taws xob yog siab-qhov kev ntseeg siab ntawm cov khoom siv hluav taws xob tiv thaiv raug txo. Nyob rau hauv kev teb rau qhov tsis sib xws ntawm cov khoom saum toj no, peb lub tuam txhab tau tsim cov koob no ntawm SPD cov ntaub ntawv pov thawj tom qab kev tshawb fawb thiab kev loj hlob mus ntev thiab kev sim ntau, uas tuaj yeem ua haujlwm zoo nrog SPD kom paub txog kev tiv thaiv xob laim, thiab daws teeb meem. Kev siv fuses lossis Circuit Court breakers ua SPDs. Tus tiv thaiv thaub qab muaj peev xwm tiv thaiv kev nyab xeeb
Qhov cuam tshuam ncaj qha ntawm kev sib xyaw ntawm cov khoom no thiab SPD yog: nyob rau hauv qhov cuam tshuam ntawm xob laim loj, nws yuav tsis cuam tshuam los xyuas kom meej qhov ua tau zoo ntawm kev tiv thaiv xob laim; Thaum SPD ua tsis tiav, lub zog me me zaus tam sim no ntws los ntawm thiab raug txiav tawm sai sai kom ntseeg tau tias muaj kev nyab xeeb ntawm daim phiaj hluav taws xob thiab kev siv hluav taws xob.
Cov khoom tsim thiab kev ua haujlwm zoo.
1. Thaum lub sij hawm overvoltage tshwm sim nyob rau hauv lub hwj chim kab, SPD conduction yuav tawg los ntawm luv luv Circuit Court, uas yuav ua rau lub hwj chim mus txawv tebchaws thiab kev huam yuaj. Tom qab SCB thaub qab tiv thaiv raug teeb tsa, Circuit Court tuaj yeem raug txiav tawm sai sai thaum lub sijhawm luv luv overvoltage tshwm sim hauv SPD, kom tsis txhob muaj xwm txheej tshwm sim los ntawm SPD tawg.
2. Thaum xob laim hla dhau, SCB tus tiv thaiv thaub qab tuaj yeem ua tau zoo kom tsis txhob muaj kev dag ntxias, yog li ntawd tus tiv thaiv surge yog ib txwm nyob rau hauv lub xeev zoo, ua kom muaj kev nyab xeeb ntawm kev siv hluav taws xob.
Nta
●Parametric tswj kev mus txawv tebchaws mechanism, tsom xam ntawm qhov tseeb xaiv ntawm kev hla tam sim no
● Lub impulse tam sim no tsawg heev, uas yog piv rau lub fuse
●High-lub zog tiv tauj, lub neej ua haujlwm ntev;
●Micro-off tsos, me me, yooj yim rau lub hwj chim tawm kom phim SPD
● Ua tiav cov lus qhia tshwj xeeb, ua tau raws li qhov xav tau ntawm SPD 11, T2, thiab T3;
●35m rail installation, nyob rau hauv txoj kab nrog installation xav tau thoob plaws lub ntiaj teb no.
Khoom Loj
Tus tiv thaiv thaub qab ua lub luag haujlwm tseem ceeb heev, tab sis nws nyob ntawm seb koj cov khoom puas zoo. Kev ua tau zoo yuav ua lub luag haujlwm zoo. Koj yuav tsum siv tus tiv thaiv thaub qab rau kev tiv thaiv xob laim. Qhov cuam tshuam ncaj qha ntawm tus tiv thaiv thaub qab uas tsim los ntawm LEIHAO Lightning Protection Company thiab SPD yog tias SPD thaub qab tiv thaiv yuav tsis tawg nyob rau hauv qhov hnyav hnyav; Tom qab SPD tawg lawm, lub zog me me zaus tam sim no raug txiav tawm sai sai kom ntseeg tau tias muaj kev nyab xeeb ntawm daim phiaj hluav taws xob thiab kev siv hluav taws xob.
Thaum lub sij hawm overvoltage tshwm sim hauv cov khoom siv hluav taws xob, SPD tau qhib, uas yuav ua rau muaj hluav taws xob mus ncig thiab kev sib tsoo. Tom qab txhim kho SCB thaub qab tiv thaiv, lub Circuit Court tuaj yeem raug txiav tawm sai sai thaum SPD yog luv luv los ntawm kev hloov hluav taws xob overvoltage, yog li zam kev sib tsoo los ntawm SPD tawg. Thaum xob laim hla dhau, SCB tus tiv thaiv thaub qab tuaj yeem ua tau zoo kom tsis txhob muaj kev dag ntxias, yog li ntawd lub zog tiv thaiv ib txwm nyob hauv lub xeev muaj txiaj ntsig, ua kom muaj kev nyab xeeb ntawm kev siv hluav taws xob.

1. Lub zog hluav taws xob yuav tsum raug txiav tawm ua ntej kev teeb tsa, thiab kev ua neej nyob yog txwv nruj.
2. Thaum txhim kho, thov txuas raws li daim duab qhia kev teeb tsa, qhov twg L, L1, L2, thiab L yog cov xaim theem, N yog cov xaim nruab nrab, thiab PE yog cov xaim hauv av. Tsis txhob txuas nws yuam kev. Tom qab kev teeb tsa tiav lawm, kaw SCB surge backup protector thiab xyuas seb qhov kev ua haujlwm zoo li cas
● Cov hlau txuas yuav tsum ruaj khov thiab txhim khu kev qha, thiab nws yuav tsum yog luv, tuab thiab ncaj.
