Molded Case Circuit Breaker (MCCB) Basic Guide
Molded Case Circuit Breakers(MCCB) chikamu chakakosha chechero system yemagetsi, ichipa inodiwa kuwandisa uye pfupi dunhu kuchengetedza. Midziyo iyi inowanzoiswa panhare huru yemagetsi yenzvimbo kuti ibvumire kudzima nyore kweiyo system kana zvichidikanwa. MaMCCB anouya muhukuru hwakasiyana uye zviyero uye anoita basa rakakosha mukuona kuchengetedzeka uye kuvimbika kwemagetsi masisitimu.
Zvikamu uye Zvimiro
Iyo yakajairwa yakaumbwa kesi yedunhu breaker ine akati wandei akakosha zvikamu, zvinosanganisira yerwendo unit, inoshanda sisitimu uye vanobatika. Iyo yerwendo unit ine basa rekuona kuwandisa uye mapfupi maseketi, nepo inoshanda sisitimu inobvumira manyore kushanda uye kure kure. Mazita akagadzirirwa kuvhura uye kuvhara maseketi sezvinodiwa, achipa dziviriro inodiwa.
Kushanda musimboti wepurasitiki kesi circuit breaker
MCCB inoshanda nekutarisa ikozvino kuyerera kuburikidza nemagetsi system. Kana yakawandisa kana dunhu diki raonekwa, iyo rwendo unit inokonzeresa vanobatika kuti vavhure, zvinobudirira kukanganisa kuyerera kwemagetsi uye kudzivirira kukanganisa kunogona kuitika kune system. Iyi mhinduro yekukurumidza yakakosha pakuchengetedza magetsi emagetsi uye yakabatana michina.
Mhando uye zvakanakira
MaMCCB anowanikwa mumhando dzakasiyana-siyana, imwe neimwe yakagadzirirwa kusangana nezvinodiwa. Iyo yakatemerwa insulation voltage yeakaumbwa kesi yedunhu redhiyo ndeye 1000V, iyo inokodzera isingawanzo chinja uye mota inotanga mu AC 50Hz maseketi. Iwo akatemerwa ekushanda voltages anosvika 690V uye ikozvino ratings anosvika 800 ACSDM1-800 (pasina kuchengetedzwa kwemota). Inoenderana nezviyero zvakaita seIEC60947-1, IEC60947-2, IEC60947-4 uye IEC60947-5-1, MCCB imhinduro inoshanda uye yakavimbika kune akasiyana siyana maapplication.
Zvakanakira kushandisa MCCBs mumagetsi masisitimu akawanda. Vanopa dziviriro inodiwa pakukanganisa kwemagetsi, kuve nechokwadi chekuchengetedzwa kwevashandi nemidziyo. Pamusoro pezvo, maMCCB ari nyore kuisa nekuchengetedza, zvichibatsira kuvandudza kushanda kwese kwesimba remagetsi.
Muchidimbu, akaumbwa ekesi mabreaker akakosha kune yakachengeteka uye yakavimbika mashandiro emagetsi masisitimu. Kunzwisisa zvikamu zvayo, mabasa, uye misimboti yekushanda kwakakosha pakuita sarudzo ine ruzivo nezve kusarudzwa kwayo nekuita. Nekuita kwavo kwakasiyana-siyana uye kugona kwekudzivirira, MCCBs ibwe repakona remazuva ano einjiniya yemagetsi uye inoita basa rakakosha mukuchengetedza zvakakosha.
