Madiki ecircuit breakers (MCBs)Zvinokosha zvikuru mumagetsi ako, zvichidzivirira imba yako kana bhizinesi rako kubva kuma "short circuits" uye kuwandisa kwemagetsi. Zvidiki, zviri nyore kuisa uye zvinopa dziviriro inokurumidza uye yakavimbika yekudzivirira matambudziko emagetsi.MCBsanoshandiswa zvakanyanya mudzimba, zvivakwa zvemabhizinesi nenzvimbo dzemaindasitiri kudzivirira moto wemagetsi nedzimwe njodzi. Mublog rino, tichanyatsoongorora zvimwe zvezvinhu zvakakosha zveMCBs, mashandiro azvo, uye kuti nei zviri chikamu chakakosha chehurongwa hwemagetsi ako.
Seimadiki ecircuit breakers anoshanda?
MCB iswichi inongoerekana yadonha kana yaona kuwanda kwemagetsi kana kuwanda kwemagetsi mudunhu. Kana magetsi ari mukati mayo adarika chiyero chayo, anoita kuti zvinhu zvinopisa kana zvemagineti zviri muMCB zvikanganise kufamba kwemagetsi uye zvikanganise kufamba kwemagetsi. MCB yakagadzirirwa kudonha nekukurumidza, kazhinji mukati memasekonzi, kana kuwanda kwemagetsi kana short circuit kwaonekwa. Kana dunhu radonha, rinodzima kufamba kwemagetsi kuburikidza nedunhu risina kunaka uye rinobatsira kudzivirira kukuvara kwemidziyo yemagetsi uye moto wemagetsi unogona kuitika.
Hunhu hwakakosha hweMCB
PakusarudzaMCB, pane zvinhu zvakakosha zvekufunga nezvazvo, zvinosanganisira rudzi rwecircuit breaker, current rating, interrupting capacity, uye trip curve. Rudzi rwecircuit breaker runofanira kukodzera system yemagetsi uye huwandu hwemagetsi ari kutakura. Current rating ndiyo inosarudza kuti current yakawanda sei.MCBinogona kubata isati yagumburwa, nepo kugona kutyoka kuri huwandu hwemagetsi anogona kutyorwa neMCB zvakachengeteka. Curve yerwendo yakakosha sezvo inosarudza kuti MCB inokurumidza sei kupindura kune overload kana short circuit uye ine macurve matatu makuru - B curve yemitoro yakajairwa, C curve yemota uye D curve yemagetsi ekushandura magetsi.
Kudzivirira kuwandisa uye kupfupisa dunhu
Kudzivirira zvinhu zvakawandisa ndiro basa guru reMCBmumagetsi. Inodzivirira michina yako newaya kubva pakupisa zvakanyanya nekuda kwemagetsi akawandisa. Kudzivirira magetsi mapfupi ndeimwe basa rakakosha rema "miniature circuit breakers". Ma "short circuit" anoitika kana paine nzira yakananga pakati pechinhu chinobuda nemutoro, zvichikonzera kuyerera kwemagetsi kwakawandisa uye njodzi huru yemoto wemagetsi. Mumamiriro ezvinhu aya ane njodzi, MCB inokurumidza kudonha, ichidzivirira kuyerera kwemagetsi kwakawanda uye ichidzivirira system kubva mukukuvadzwa kunogona kuitika.
mukupedzisa
Mukupedzisa,MCBchikamu chakakosha uye chakakosha chemagetsi. Anodzivirira imba yako kana bhizinesi rako kubva mukuzara kwemagetsi uye mashort circuits, achidzivirira midziyo yako uye achidzivirira mamiriro ezvinhu anogona kuva nengozi. MCB yakakodzera inofanira kusarudzwa yedunhu rako, tichifunga nezvezvinhu zvakaita se rated current, kukanganisa kugona uye trip curve. Kugadziriswa nekuongororwa nguva dzose kweMCB dzako kuchaita kuti dzirambe dzichiita mabasa adzo akakosha zvinobudirira, dzichidzivirira magetsi ako uye dzichiona kuchengetedzeka.
