1. Txuas cov ntsiab cai rau kev ua haujlwm txuas ntxiv hluav taws xob (UC) thiab cov kab hluav taws xob voltage
Rau Ucyog qhov siab tshaj plaws hluav taws xob hluav taws xob voltage ib tug arester tuaj yeem tiv thaiv tsis tu ncua. Cov qauv xaiv xaiv muaj xws li:
Ncaj qha hauv nruab nrab nruab nrab
UC ntau dua lossis sib npaug rau 1.25 × system system theem kev ntsuas theem hluav taws xob
Piv txwv li: rau 35kv system (Max voltage 40.5Kv),UC ntau dua los yog sib npaug rau 50.6Kv.
Cov nruab nrab tsis ncaj qha nruab nrab
Yog tias ib leeg-theem av yuam kev raug tshem tawm hauv2 teev:
UC ntau dua los yog sib npaug rau 1.1 × Kab voltage
Piv Txwv: Rau 10kV system, xaivUC ntau dua los yog sib npaug rau 12kv.
Kev Kawm Txog: Cov nroj tsuag tshuaj muaj cov tshuaj lom neeg muaj kev paub txog Artester Thermal khiav tawm thiab tawg vim yog Harmonic-Induced UC tsis yooj yim.
2. Tseem ceeb ntawm ntxhab pem hauv ntej agulse withst nqi
Qhov ntsuas no cuam tshuam txog ib qho kev muaj peev xwm tiv thaiv kev tiv thaiv kev kub ntxhov ntau zaus (1μs yaig hluav taws xob), qhov tseem ceeb rau cov cuab yeej muaj kev nyab xeeb:
Kev Txhais Tes & Cov Qauv
Withstand voltage cleepnessNtau dua los yog sib npaug rau 100 kV / μskom ntseeg tau tias nanosecond-qib hluav taws xob dissipation.
Residual Voltage Piv (Up / System Voltage) tsawg dua lossis sib npaug rau 1.8Txhawm rau tiv thaiv cov rwb thaiv tsev transformer.
Daim Ntawv Thov Hauv Xaiv
Photovoltaic Nroj Tsuag: Siv ntes nrog20ka nominal tawm tam sim noTxhawm rau kom phim high-zaus xob laim.
Kev Kawm Txog: Ib qho cua ua liaj ua teb raug kev txom nyem ntau dua ¥ 10 lab hauv kev poob vim tsis muaj qhov sib luag
3. Kev Koom Tes Tsim Qauv & Kev Tiv Thaiv Tsis Zoo
Multi-parameter txoj kev sib koom tes
UC thiab cov hluav taws xob hluav taws xob (koj):
Koj siab dua los yog sib luag rau ib qho kev sib tw ib ntus(piv txwv li, 1.3 × qhov system system thaum lub zog tsis lees paub).
Nominal tawm tam sim no (hauv):
Xaiv rawsHuab Cua Thapundrivation (Td)Cov. Rau TD ntau dua lossis sib luag rau 40 thaj tsam, xaivNtau dua los yog sib npaug rau 10ka.
Kev hloov chaw tshwj xeeb
DC system ntes: Thawjlub zog poob (tsawg dua los yog sib npaug rau 10W)thiab lub sij hawm ntev ruaj khov.
Polymer-lub tsev ntes: Zoo tagnrho rau kev co-nquag ib puag ncig (piv txwv li, kev tsheb ciav hlau) vim tias yog cov ntaub ntawv pov thawj zoo tshaj plaws vs.
