Wopatsa Wapamwamba Wapamwamba wa Air Circuit Breaker
CDADAndi katswiri wopanga zida zamagetsi zochokera ku China. Tikukupemphani kuti mufufuze mitundu yathu ya Air Circuit Breakers, yomwe ili ndi mitundu yosiyanasiyana komanso ikugwirizana ndi miyezo yapadziko lonse lapansi. Kupyolera mu kuwongolera khalidwe labwino, tadzipereka kukupatsani zinthu zapamwamba komanso ntchito zambiri.
Kodi Air Circuit Breaker N'chiyani?
An Air Circuit Breaker (ACB) ndi chipangizo chosinthira mphamvu chotsika kwambiri chomwe chimapangidwa kuti chiteteze makina ogawa magetsi kuti asachuluke, mabwalo amfupi, ndi zovuta zapadziko lapansi. Amagwira ntchito pamagetsi okwana 690V AC (50/60Hz) omwe ali ndi mavoti apakati pa 630A mpaka 6300A, ma ACB amagwira ntchito ngati zida zodzitetezera m'ma switchboards, malo ogawa magetsi, ndi zomangamanga zofunika kwambiri zamafakitale.
Mosiyanama ma molded case circuit breakers (MCCBs), Ma ACB amagwiritsa ntchito mpweya wa mumlengalenga ngati njira yozimitsira arc, kugwiritsa ntchito makina apamwamba kwambiri a arc chute ndi maginito owulutsira maginito kuti azimitse bwino mafunde olakwika. Mapangidwe otsegukawa amalola kuti zigawo zamkati ziziwoneka bwino, zomwe zimathandizira kukonza zodzitchinjiriza ndikukulitsa moyo wantchito mpaka zaka 15-20 kapena kupitilira apo ndikugwiritsa ntchito moyenera.
