Kufotokozera Kwachidule:

W1 mndandanda wanzeru otsika-voltage air circuit breaker (omwe amatchedwanso circuit

breaker) ndi oyenera kugawa maukonde ndi pafupipafupi AC 50Hz, oveteredwa voteji mmwamba

mpaka 660V (690V) ndi pansipa ndipo oveteredwa panopa kuyambira 200A kuti 6300A. Zazolowera

kugawa mphamvu zamagetsi ndikuteteza mizere ndi zida zamagetsi kuti zisachuluke,

undervoltage, short circuit, single-phase grounding ndi zolakwika zina. Wowononga dera ali ndi

chitetezo chanzeru komanso chitetezo chokhazikika, chikhoza kupititsa patsogolo magetsi

kudalirika ndikupewa kuzimitsa kwamagetsi kosafunikira. Pakadali pano, ili ndi kulumikizana kwamtundu wotseguka

mawonekedwe ndipo angagwiritsidwe ntchito pazigawo zinayi zakutali kuti zikwaniritse zofunikira pakuwongolera

Center ndi automation system. Wowononga dera ali ndi mphamvu yolimbana ndi 8000v pa

kutalika kwa 2000 metres (yokonzedwa molingana ndi miyezo yokwera mosiyanasiyana, yokhala ndi pazipita

voteji osapitirira 120oov). Wowononga dera wopanda wowongolera wanzeru ndi sensa

chitha kugwiritsidwa ntchito ngati chodzipatula, cholembedwa kuti Wophwanya dera amatsatira miyezo monga GB

14048.2 Low-voltage switchgear ndi controlgear-Gawo 2: Ma Circuitbreaker ndi IEC60947-2

Ma switchgear otsika-voltage ndi zida zowongolera-Gawo 2: Ophwanya ma Circuit.
