Lub npe: Cht 1- b40 / 2p dc: 1500v
Zaj piav
Cov cuab yeej no yog siv los tiv thaiv DC cov voj voog los ntawm kev puas tsuaj los ntawm kev hloov pauv ntawm cov ntsiab lus ntawm cov ntsiab lus ntawm cov ntsiab lus ntawm cov ntsiab lus sai thiab muaj zog tawm .
Tub Ntxhais Ua Haujlwm Txoj Cai
- Kuaj tau ntawm cov kev hloov pauv hloov: nws yuav mus rau kev tiv thaiv thaum tus nqi saib xyuas ntau dua tus nqi ntsuas ({} lub sij hawm ntawm cov ntsuas hluav taws xob).
- Tso tawm lub zog tawg: los ntawm kev siv cov khoom siv xws li cov varistors thiab roj tawm roj rau hauv av lossis dissipated li cua sov zog .
- Rov qab los sai: Tom qab ua haujlwm ntawm SPD, nws yuav cia li rov qab mus rau lub xeev siab-impedance, yam tsis muaj cuam tshuam rau lub zog hluav taws xob ntawm lub zog {}}
Cov Tiv Thaiv Tseem Ceeb thiab lawv cov haujlwm
- Varistor (mov): Yuav kom nqus tau cov kev cai nruab nrab, nws lub sijhawm teb ntawm qib nanosecond qib tau ua rau laus .
- Roj tso tawm roj (GDT): Txhawm rau tawm qhov loj tam sim no (uas dhau los ntawm-tam sim no amperes tuaj yeem ua tiav lub micritions, thiab nws yuav ua kom muaj zog ua arcs .
- Voltage breadage suppressing Diode (TVs): Nws muaj ntau yam kev nkag siab ntawm cov khoom siv picosecond ntawm cov khoom muaj peev xwm tsawg, feem ntau nruab nrog lwm cov sib xyaw.
- Decoupling inductor / kev tawm tsam: nws tuaj yeem sib koom ua ke ntawm cov txheej txheem tiv thaiv ntau qib los xyuas kom meej tias lub zog tuaj yeem tso tawm los ntawm kauj ruam.
Raug Daim Ntawv Teev Lus
Photovoltaic (tiv thaiv lub hnub ci ntsa iab thiab inverers), kev sib txuas lus lub hauv paus mov), Kev Sib Txuas Lus DC hluav taws xob (rau cov tsheb ciav hlau lossis chaw khaws hluav taws xob
Qhov sib txawv ntawm DC SPD thiab AC SPD
- ACD SPD ua haujlwm los ntawm kev siv cov nonlinar Cheebtsam, nws tau ua rau cov khoom siv hluav taws xob sai sai Xob laim induction lossis pib / nres ntawm cov khoom siv hluav taws xob tsim kom muaj nthwv tawm, tus ACT AC Surge tiv thaiv tuaj yeem ua kom sai.
- Lub koomhaum ua haujlwm ntawm DC SDP muaj cov ac spd {{}}}}}}}}}}}}}}}}}} Txawm li cas los xij, tab sis yuav tsum tau siv sijhawm ntev los ntawm DC voltage yuav tsum tau raug txiav txim siab {{4 {}} Piv txwv, hauv DC SPORTIVE tiv thaiv cov khoom siv hluav taws xob los ntawm xob laim lossis lwm yam .
Xaiv Xaiv Kev Xaiv
- Qhov ntsuas qib: yuav phim rau lub system ua hauj lwm voltage (xws li lub photovoltaic feem ntau yog 1000V dc) .
- Los ntawm-tam sim no muaj peev xwm (hauv): Xaiv raws li qhov kev cia siab tam sim no (xws li 20ka, 40ka) {3} {3}
- Clamp Voltage: Cov voltage seem yuav tsum qis dua qhov wordstand theem ntawm ntaus ntawv .
- Ib puag ncig kev yoog tau: yuav tsum tau xav txog cov hmoov av, dej tsis tau) thiab qhov kub thiab txias}
Kev Txij Nkawm thiab Ua Phem Tsim
- Kev soj ntsuam tsis tu ncua: Tom qab cov varistor hnub nyoog, cov toppage nce thiab nws yuav tsim cua sov .
- Txhaum kev qhia: Qee cov khoom lag luam muaj lub qhov rai pom lossis cov chaw taws teeb kom pom kev yuav tsum tau ua qhov kev hloov .
- Kev nyab xeeb tsis ua hauj lwm: thaum muaj cov khoom lag luam zoo tsis tau, nws yuav cia li txiav tawm kom tsis txhob muaj kev pheej hmoo ntawm Circuit Court {}}
