Tsanangudzo Pfupi
Iyo W2-1 600 Series yakangwara mhepo yedunhu breaker (inozonzi sedunhu
breaker) inokodzera kugovera network ine frequency ye AC 50Hz, yakayerwa kushanda
voltage inosvika 690V uye yakayerwa ikozvino kubva ku200Ato 1600A. Inoshandiswa kugovera
simba remagetsi uye kudzivirira mitsara nemidziyo yemagetsi kubva pakuremerwa, pfupi pfupi,
undervoltage single-phase grounding(leakage) nezvimwe zvikanganiso. The circuit breaker
ine hungwaru hwekudzivirira basa uye chaiyo yakasarudzika yekudzivirira, inogona kuvandudza
powersupplyreliability uye kudzivirira kudzima kusingakoshi kwemagetsi. Zvichakadaro, yakavhurika
typecommunication interface, iri nyore kune fieldbus connection, uye inogona kuva
inoshandiswa kune mana ari kure mashandiro kusangana nezvinodiwa zvekutonga centre uye
automation system. Yakashongedzerwa inoenderana leakage transformer uye yakangwara
controller, leakage protection inogona kuwanikwa.
Iyo yedunhu inotyora ine yakayerwa kushanda ikozvino ye630A uye pazasi inogona zvakare kushandiswa
kuwandisa, kupfupika, kurasikirwa kwechikamu, undervoltage uye kuchengetedzwa kwepasi kwemota mu AC
50 (60) Hz, 400V yekugovera network. Pasi pemamiriro ezvinhu, muparadzi wedunhu anogona
shandirawo kune zvisingaite switching yedunhu uye isingawanzo kutanga yemota.Dunhu
breaker inoenderana neGB14048.1-2012 Low-voltage switchgear uye controlgear-Chikamu 1:
