Class I II Surge Protective Device

Class I II Surge Protective Device yog ib qho kev sib koom ua ke T1+T2 lub zog tiv thaiv kev tiv thaiv tsim los rau qis-voltage AC faib tshuab. Nws ua ke lub siab - lub zog tso tawm muaj peev xwm ntawm Chav Kawm I xob laim ntes nrog lub nrawm nrawm nrawm nrawm ntawm Class II SPD, pab tiv thaiv cov khoom siv hluav taws xob qis los ntawm cov hluav taws xob ncaj qha tam sim no, cuam tshuam xob laim, thiab daim phiaj sib hloov overvoltage. Piv nrog cov tsoos sib cais T1 thiab T2 surge arresters, cov qauv kev sib xyaw ua kom yooj yim rau kev tsim cov txee vim tias tsis muaj kev cuam tshuam sab nraud lossis kev sib cuam tshuam nruj - theem kev teeb tsa yuav tsum tau ua.

Cov cuab yeej no tsim nyog rau 220 / 380V AC 50 / 60Hz systems thiab feem ntau tau teeb tsa ntawm cov khoom xa tuaj loj, chav fais fab, cov khoom siv sab nraum zoov, thiab pem hauv ntej kawg ntawm cov hluav taws xob rhiab heev. Nrog rau kev tsim qauv DIN rail, qhia meej txog xwm txheej, thiab kev ua haujlwm kub ntau, nws muab kev siv hluav taws xob thiab kev tiv thaiv hluav taws xob rau cov tuam tsev lag luam, cov chaw tsim khoom, cov ntaub ntawv chav, photovoltaic-txog cov khoom xa tawm, thiab cov khoom siv hluav taws xob muaj tseeb.

• Integrated T1+T2 tiv thaiv qauv rau ob qho tib si xob laim tam sim no tawm thiab induced surge voltage clamping.
• Ua tau -hauv kev txawj ntse lub zog sib txuam tsim, txo qhov xav tau rau cov khoom siv sab nraud decoupling.
• Haum rau 220/380V qis-voltage AC fais fab kev faib tshuab thiab 3P + N peb-theem plaub-wire applications.
• Muaj peev xwm tam sim no muaj peev xwm nrog T1 Iimp xaiv ntawm 12.5kA lossis 25kA siv 10/350us waveform.
• T2 paug muaj peev xwm nrog nominal paug tam sim no ntawm 20kA los yog 40kA thiab siab tshaj tawm tam sim no ntawm 60kA los yog 80kA.
• Fast teb lub sij hawm ntawm<=25ns and voltage protection level of <=1.5kV for effective downstream equipment protection.
• Lub qhov rais xwm txheej qhia ntsuab rau kev ua haujlwm ib txwm muaj thiab liab rau qhov tsis ua haujlwm, ua rau kev saib xyuas yooj yim dua.
• 35mm txheem DIN rail mounting rau ceev installation nyob rau hauv lub thawv faib thiab switchgear txee.

Ib tug qauv qauv configuration yog SPD-T1+T2-25/440-3P+N. Hauv cov qauv no, T1+T2 qhia txog kev tiv thaiv kev tiv thaiv kev tiv thaiv kev kub ntxhov hauv chav kawm I thiab Class II; 25 sawv cev rau T1 nominal impulse tam sim no ntawm 25kA; 440 qhia qhov siab tshaj plaws ua haujlwm tsis tu ncua ntawm 440V AC; thiab 3P + N yog hais txog peb-theem plaub-xaim kev teeb tsa. Hom ntawv no pab engineers xaiv qhov tsim nyog surge tiv thaiv ntaus ntawv raws li lub hwj chim system, xob laim theem, thiab txee layout.

Cov cuab yeej siv cov qauv kev tiv thaiv dual uas sib txuas cov raj xa hluav taws xob rau Chav Kawm I xob laim tam sim no tawm thiab cov qauv varistor rau Class II surge voltage clamping. Thaum lub siab - lub zog hluav taws xob los ntawm cov hluav taws xob ncaj qha nkag mus rau hauv txoj kab hluav taws xob, Chav Kawm I theem ua ntej thiab tso tawm cov hluav taws xob loj rau lub ntiaj teb. Thaum hluav taws xob los yog hloov hluav taws xob overvoltage tshwm rau ntawm lub kaw lus, Qib II theem teb sai sai thiab clamps qhov hluav taws xob mus rau qib kev nyab xeeb. Ob theem sib koom ua ke tau txais txiaj ntsig, pab txo qis kev ntxhov siab ntawm cov hluav taws xob qis qis, cov cuab yeej tswj hwm, tsav, ntsuas, cov khoom siv hluav taws xob sib txuas lus, thiab lwm yam khoom siv hluav taws xob rhiab heev.

• Cov khoom tseem ceeb ntawm kev lag luam, thaj chaw, thiab cov tsev lag luam.
• LPZ0 rau LPZ1 xob tiv thaiv cheeb tsam cuam tshuam hauv qis-voltage AC systems.
• Muaj zog -tam sim no thiab tsis muaj zog- cov cuab yeej siv tam sim no yuav tsum muaj kev sib koom tes tiv thaiv kev kub ntxhov.
• Sab nraum zoov hluav taws xob faib lub thawv thiab cov hluav taws xob vaj huam sib luag raug teeb meem hluav taws xob.
• Pem hauv ntej-kev tiv thaiv kawg rau cov khoom siv hluav taws xob muaj tseeb, tswj vaj huam sib luag, thiab cov tshuab automation.
• Kev faib khoom siv TN-S, TN-C, TN-C-S, TT, lossis IT earthing npaj.

Kev teeb tsa yuav tsum ua kom tiav los ntawm tus kws tshaj lij hluav taws xob tsim nyog tom qab cov khoom siv hluav taws xob sab saud tau raug txiav tag nrho. Lub SPD yuav tsum tau nruab tom qab lub ntsiab nkag mus ntawm qhov qis -voltage tis system thiab tsau ruaj khov ntawm 35mm DIN rail. Txuas lub L theem conductors, N nruab nrab tus neeg xyuas pib, thiab PE grounding conductor raws li cov khoom cim. Txhawm rau txhim kho kev tiv thaiv kev ua tau zoo, tag nrho qhov txuas ntev yog pom zoo kom tsis pub ntau tshaj 0.5m, txo cov hlau lead inductance thiab seem hluav taws xob thaum lub sij hawm tso tawm.

Ib lub fuse thaub qab uas tsim nyog los yog qhov hluav taws xob hluav taws xob yuav tsum tau nruab rau sab saud kom tsis txhob luv luv -kev pheej hmoo ntawm hluav taws xob yog tias cov cuab yeej tiv thaiv hluav taws xob nce mus txog qhov kawg - ntawm - lub neej tsis ua haujlwm. Tom qab energizing lub system, xyuas qhov xwm txheej qhov rai. Ntsuab qhia tau hais tias ib txwm muaj kev pabcuam; liab qhia tias tsis ua hauj lwm thiab chav tsev yuav tsum tau hloov tam sim ntawd.

• Tshawb xyuas lub cuab yeej txhua rau lub hlis lossis ua ntej lub caij cua daj cua dub.
• Paub meej tias qhov taw qhia tseem ntsuab thiab xyuas tias cov terminals nruj tsis muaj cua sov txawv txav.
• Hloov lub cuab yeej thaum qhov taw qhia tig liab, tom qab muaj kev tshwm sim xob laim hnyav, lossis thaum xav tias kev tiv thaiv tsis ua haujlwm.
• Fais fab tuag ua ntej hloov thiab siv lub cuab yeej tshiab nrog tib qhov tshwj xeeb kom tsis txhob muaj qhov tsis sib xws.

Tsis txhob nruab, tshem tawm, lossis ua haujlwm lub cuab yeej thaum muaj zog. Tsis txhob siv SPD tshaj nws qhov ntsuas kev ua haujlwm tsis tu ncua lossis hauv cov tshuab ua haujlwm dhau. Cov cuab yeej yuav tsum raug xaiv raws li qhov system voltage, earthing type, xob laim theem, installation txoj hauj lwm, thiab yuav tsum tau muaj peev xwm tawm. Rau cov khoom faib loj thiab siab -kev pheej hmoo sab nraum zoov hluav taws xob, T1+T2 kev sib koom ua ke surge arrester muab txoj kev tiv thaiv ntau dua thiab sib koom ua ke dua li siv cov khoom sib cais yam tsis muaj lub zog sib txuam.

Rau qhov kev xaiv los yog kev yuav khoom ntau, thov muab qhov system voltage, earthing system, ncej configuration, yuav tsum tau Iimp thiab Imax theem, txee installation txoj hauj lwm, thiab kwv yees kom muaj nuj nqis. Peb pab neeg tuaj yeem pab kom paub meej tias qhov tsim nyog Class I II Surge Protective Device configuration thiab muab cov ntaub ntawv qhia, kev txhawb nqa, thiab xa cov ntaub ntawv rau koj qhov project tiv thaiv hluav taws xob.
