MLM1 MCCB
Chogulitsa Tsatanetsatane
Kufotokozera kwa Zamalonda
Mndandanda wa MLM1 ndi MGM1 ndi Molded Case Circuit Breakers (MCCBs) zosiyanasiyana zomwe zimapangidwa kuti zigwire bwino ntchito pakugawa magetsi komanso kuteteza magalimoto. Mzere wonsewu wazinthu umaphimba mitundu yambiri, yokhala ndi kukula kwa mafelemu kuyambira 63A mpaka 1250A ndi mafunde osinthika kuyambira 10A mpaka 800A, omwe amapezeka mu mawonekedwe a 3-pole ndi 4-pole.
Chinthu chofunika kwambiri ndi kutulutsidwa kwawo koteteza, komwe kumagwiritsa ntchito njira yamagetsi yotenthetsera ndi maginito. Chida chotenthetsera chochedwa nthawi yosinthira chimasamalira kupitirira muyeso, pomwe chipangizo chamagetsi chimapereka kugwedezeka nthawi yomweyo kwa ma short-circuits. Mitundu inayake imakonzedwa kuti iteteze kugawa kapena chitetezo cha mota, ndipo mawonekedwe ake amaperekedwa mwatsatanetsatane. Ma breaker ali ndi mphamvu yotenthetsera yokwera kwambiri mpaka 800V komanso mphamvu yoopsa yothyola ma short-circuit (ICU) mpaka 80kA pa 415V AC, yokhala ndi mitengo yodziwika bwino ya makina a 690V AC.
Pa kukhazikitsa ndi kukonza mapulogalamu, deta iyi imapereka deta yofunika kwambiri. Izi zikuphatikizapo madera ofunikira a conductor pa rating iliyonse yamagetsi, kuchuluka kwa mphamvu zomwe zimatayika pamitundu yosiyanasiyana, komanso zinthu zina zomwe zimapangitsa kuti kutentha kusinthe kupitirira 40°C, mpaka 60°C. Zowonjezera zambiri, kuphatikizapo kutulutsidwa kwa shunt, kutulutsidwa kwa under-voltage, ndi ma contact othandizira, zimathandizira magwiridwe antchito. Mogwirizana ndi miyezo ya IEC, ma MCCB awa amadziwika ndi mphamvu zawo zosweka kwambiri, kapangidwe kake koyenera, komanso kusinthasintha kumadera osiyanasiyana amafakitale, zomwe zimapangitsa kuti akhale chisankho chodalirika cha machitidwe ovuta ogawa magetsi.
Makhalidwe Oteteza
Kutulutsa kwa maginito otenthetsera kumakhala ndi khalidwe lochedwa nthawi. Kutulutsa kwa maginito kokha kumapereka kugwedezeka nthawi yomweyo; makhalidwe ake oteteza kufalikira kwa zinthu alembedwa patebulo pansipa.
