Kev tsis

SPD Pawg lossis Hom

Ob hom tseem ceeb ntawm SPDs yog qhov txwv qhov hluav taws xob thiab qhov hloov pauv hluav taws xob. Voltage limiting Cheebtsam hloov pauv hauv impedance raws li qhov hluav taws xob nce, ua rau clamping qhov hloov pauv hloov pauv. Cov khoom siv hluav taws xob hloov pauv "qhib" ib zaug dhau qhov pib qhov hluav taws xob ntau dua thiab tam sim poob mus rau qhov tsis muaj qhov cuam tshuam. Feem ntau cov kab ke niaj hnub no suav nrog ob hom kev sib koom ua ke los sib sau ua ke qhov muaj zog thiab txwv qhov tsis muaj zog ntawm txhua tus neeg ib feem.

Piv txwv ntawm kev txwv cov khoom siv hluav taws xob yog cov hlau oxide varistors (MOVs) thiab kev tiv thaiv hluav taws xob ib ntus (TVS) diodes. Cov khoom siv hluav taws xob hloov pauv suav nrog cov raj tso pa tawm (GDTs) thiab cov khoob khoob.

Yuav Ua Li Cas Sib Piv SPD Pawg

Cov khoom tiv thaiv tuaj yeem muab piv rau lawv ua li cas raws li cov hauv qab no.

Lub Sijhawm Teb

Lub sijhawm teb ntawm ib qho kev tivthaiv tsuas yog txhais tau hais tias cov khoom tivthaiv tau sai npaum li cas thaum qhov pib nce siab. Cov khoom siv hluav taws xob txwv tsis pub siv - TVS diodes, tshwj xeeb - muaj lub sijhawm teb tau sai dua qhov hloov pauv hluav taws xob (piv txwv li qhov khoob thiab GDTs).

Ua Raws Li Tam Sim No

Qhov tshwm sim no txwv rau cov khoom siv hloov hluav taws xob. Kev ua raws tam sim no tshwm sim thaum lub cuab yeej tiv thaiv tsis tuaj yeem "tua tawm" (piv txwv li rov qab mus rau lub xeev tsis muaj kev tiv thaiv siab) tom qab qhov xwm txheej hloov pauv vim yog qhov hluav taws xob qis qis hla cov khoom. Qhov no tso cai rau tam sim no txuas ntxiv mus los ntawm lub cuab yeej thaum lub sijhawm ua haujlwm ib txwm muaj.

Qhov tshwm sim no tsis tshua muaj kev txhawj xeeb hauv AC systems, vim tias kev hla dhau xoom tso cai rau cov khoom siv kom tig tawm thiab rov qab mus rau lub xeev tsis muaj kev tiv thaiv siab. Txawm li cas los xij, DC system siv cov khoom siv hloov hluav taws xob xav tau kev txiav txim siab ntxiv.

Cia-Los ntawm Voltage

Thaum muaj qhov tshwm sim, qhov tso tawm los ntawm qhov hluav taws xob yog qhov ntau ntawm qhov hluav taws xob uas cov khoom siv tso cai kom mus txog cov cuab yeej txuas. Rau qhov tso tawm qhov hluav taws xob, diodes txwv qhov hluav taws xob qhov zoo tshaj plaws thiab ua kom nws qis tshaj, tab sis qhov txiaj ntsig tau txwv vim tias diodes tsis muaj txiaj ntsig ntawm kev tuav cov dej ntws loj dua.

Ib qho kev tivthaiv tsis tau hais los saum toj no yog ib qhov zoo tshaj plaws lossis tsis zoo nyob hauv ib qho ntawm peb thaj chaw no yog MOV, vim tias MOVs feem ntau suav tias yog kev pabcuam hauv txhua qeb, ua haujlwm li jack-of-all-trades, tabsis tsis yogzoo tshajnyob rau hauv ib leeg.

Nco ntsoov tias feem ntau cov khoom SPD ntawm kev ua lag luam niaj hnub no yog cov qauv siv sib txuas uas yog kev sib xyaw ua ke ntawm ntau yam khoom ntxiv. Cov khoom lag luam no sib npaug qhov zoo thiab qhov tsis zoo ntawm txhua tus neeg sib koom los muab cov chaw muaj kev tiv thaiv zoo tiv thaiv ntau hom kev nce.

Surge Protective Device Performance Features Paub

Kev paub tus kheej cov khoom sib xyaw tau pab kom nkag siab, tab sis dab tsi ua rau cov qauv rau SPDs yog qhov ua tau zoo lossis cov yam ntxwv rau txhua lub cuab yeej.

Tom qab txheeb xyuas lub zog faib hluav taws xob uas SPD yuav tsum txuas nrog, ib tus yuav tsum sib piv cov khoom siv sib txawv los ntawm cov hauv qab no:

1. Qhov Ua Haujlwm Ntau Tshaj Plaws Nruam (MCOV). MCOV yog qhov siab tshaj plaws uas lub cuab yeej tuaj yeem tiv taus thiab txuas ntxiv ua haujlwm kom raug. Feem ntau, MCOV yuav tsum yog tsawg kawg 25% siab dua qhov muab khoom siv hluav taws xob, tab sis yog tsav los ntawm cov qauv cuam tshuam. Piv txwv li, nVent ERICO SPDs tsim rau 120 lub npe khoom siv hluav taws xob muaj MCOV ntawm 170, thiab rau 240 lub npe nom tswv tshuab hluav taws xob SPD's MCOV yog 275.

2. Voltage Protection Rating (VPR) lossis Voltage Protection Level (Up). Kev tiv thaiv kev ntsuas hluav taws xob thiab qib kev tiv thaiv hluav taws xob tau ntsuas los ntawm UL thiab IEC, ntsig txog, uas cuam tshuam nrog kev tso-dhau qhov hluav taws xob ntawm lub cuab yeej. UL 1449 suav nrog kev sim uas siv 6kV/3kA ua ke ua ntu zus mus rau lub cuab yeej thiab ntsuas qhov ntsuas hluav taws xob cia los ntawm, txiav txim siab ntsuas qhov ntsuas hluav taws xob tiv thaiv (VPR). IEC 61643-11 muaj qhov ntsuas zoo ib yam thiab hais txog nws raws li qib kev tiv thaiv hluav taws xob (nce).

3. Nominal Discharge Tam Sim No (Hauv) Kev Ntsuam Xyuas. Txhais los ua tus nqi siab tshaj ntawm qhov tam sim no uas tuaj yeem ua tau los ntawm SPD nrog kev hloov pauv ntawm 8/20μs qhov twg SPD tseem ua haujlwm tom qab 15 thov nce. Ib UL 1449, cov tuam txhab tsim khoom yuav tsum xaiv lub npe tawm tam sim no los ntawm daim ntawv teev npe ua ntej (3ka, 5kA, 10kA lossis 20kA) rau qhov kev xeem no.

4. Qhov xwm txheej qhia. Qhov ntsuas qhov xwm txheej-uas tej zaum yuav yog lub ntsuas ntsuas lub tshuab, LED lossis lub tswb tswb deb-muab qhov yooj yim Mus/Tsis-Mus qhia. Kev ntsuas ntsuas nce yog qee yam xav txog ntau yam tseem ceeb rau SPD qhov tshwj xeeb. Txawm li cas los:

5. Kev Muaj Peev Xwm Muaj Peev Xwm Tam Sim No lossis Qhov Kev Ntsuas Siab Tshaj. Cov neeg tsim khoom feem ntau teev cov kev ntsuas no ua ib qho qhia txog kev ua siab ntev ntawm lub cuab yeej, lossis ib zaug ib zaug siab tshaj plaws tam sim no uas lub cuab yeej tuaj yeem ua tau. Txawm hais tias cov kev ntsuas no tshwm sim ntawm ntau lub vev xaib chaw tsim khoom thiab cov ntawv teev tseg, UL lossis IEEE tsis txhais cov kev ntsuas no. Qhov no tso cai rau txhua lub chaw tsim khoom los tsim lawv tus kheej qhov xav tau kev xeem (yog tias muaj) thaum kawg ua rau lawv tsis ntseeg tau qhov ntsuas ntawm kev ua tau zoo.
