Kunzwisisa Mcb Circuit Breakers: Gwaro Rakazara
Munyika yeinjiniya yemagetsi nekuchengetedzeka, ma miniature circuit breakers (MCBs) anoita basa guru mukudzivirira ma electrical circuit kubva pakuwanda kwemagetsi uye ma short circuit. Midziyo iyi inokosha kuma system emagetsi emumba neemabhizinesi, ichidzivirira midziyo yemagetsi newaya kubva mukukuvadzwa kunokonzerwa ne overcurrent.
Chii chinonzi Mcb circuit breaker?
MCB circuit breaker iswitch inodzima kufamba kwemagetsi mucircuit kana yaona chimwe chinhu chisina kujairika, senge overload kana short circuit. Kusiyana nemafuse echinyakare, ayo anofanira kutsiviwa mushure mekunge aputika, maMCB circuit breaker anogona kudzoserwa patsva mushure mekunge adonha, zvichiita kuti ave sarudzo iri nyore uye inoshanda yekudzivirira magetsi mucircuit.
Mcb circuit breaker inoshanda sei?
Kushanda kwemaMcb circuit breakers kwakavakirwa pamaitiro maviri makuru: kupisa uye magineti.
1. Maitiro ekupisa:Chikamu ichi chinopindura mamiriro ekuwanda kwemagetsi. Kana magetsi ari kufamba nemudunhu adarika simba remagetsi rinopihwa necircuit breaker, kupisa kunobva kwaita kuti bimetallic strip iri mukati mecircuit breaker ikotama. Kana kukotama kwasvika padanho rakati, bimetallic strip inotanga nzira yekutyora magetsi, ichivhara magetsi.
2. Maitiro eMagineti: Iyi nzira yakagadzirirwa kupindura kumagetsi mapfupi. Kana magetsi mapfupi akaitika, magetsi anomhanya nekukurumidza, zvichigadzira simba remagineti rakasimba rinodhonza lever, zvichiita kuti circuit breaker igumbuke nekukurumidza. Mhinduro iyi yekukurumidza yakakosha mukudzivirira kukuvara kwezvikamu zvemagetsi uye kuderedza njodzi yemoto.
Mhando yemuchina wekushandisa weMcb
MaMcb circuit breakers anowanikwa mumhando dzakasiyana-siyana, imwe neimwe yakagadzirirwa chinangwa chaicho:
Rudzi B: Pakushandisa mudzimba, rudzi urwu rwecircuit breaker runodarika simba remagetsi ka3 kusvika ka5. Rwakakodzera macircuit ane zvinhu zvinodzivirira, zvakaita semwenje nekupisa.
Rudzi C: Rudzi urwu rwakagadzirirwa kushandiswa mumabhizinesi nemaindasitiri, ne trip current inopetwa ka5 kusvika ka10 kupfuura rated current. Yakakodzera macircuit ane inductive loads, akadai semota nematransformer.
Rudzi D: Rudzi urwu runoshandiswa mukushandiswa kwemagetsi ane mafungu emvura anopinda zvakanyanya, akadai semamota makuru nematransformer. Anoputika nekagumi kusvika makumi maviri kupfuura simba remagetsi rakarongwa.
Zvakanakira kushandisa Mcb circuit breakers
1. Kuchengetedzwa: Mcb circuit breakers inopa nzira yakavimbika yekudzivirira macircuit kubva pakuzara kwemagetsi uye mashort circuit, zvichideredza zvikuru njodzi yemoto wemagetsi nekukuvara kwemidziyo.
2. Zviri nyoreKusiyana nemafuse anoda kutsiviwa mushure mekuputirwa, maMcb circuit breakers anogona kudzorerwa zviri nyore, izvo zviri nyore kushandisa.
3. Dhizaini Yakabatana: MaMCB circuit breakers madiki uye madiki pane zvishandiso zvekuchengetedza circuit zvechinyakare, zvichibvumira kushandiswa kwakanaka kwenzvimbo mumapaneru emagetsi.
4. Inodhura Zvishoma: Kunyange hazvo mari yekutanga ingave yakakwira kupfuura mafiyuzi, kuchengetedza kwenguva refu kubva mukukuvara kushoma kwemidziyo uye nyore kwekugadzirisa patsva kunoita kuti Mcb circuit breakers ive sarudzo inodhura zvishoma.
Kuisa uye Kugadzirisa
Kuisa macircuit breaker kunofanirwa kuitwa nenyanzvi yemagetsi ine hunyanzvi kuti ive nechokwadi chekuti mitemo yemagetsi yemuno uye mitemo yekuchengetedza inoenderana. Kuongororwa nguva nenguva kwekugadzirisa kunokurudzirwawo kuti ive nechokwadi chekuti macircuit breaker ari kushanda zvakanaka uye kuona chero matambudziko angangoitika asati anyanya kuipa.
Ndeupi musiyano uripo pakati peMCB neMCCB breakers?
MaMCB: Anowanzo shandiswa mumashandisirwo emagetsi emagetsi epasi neakaderera, kazhinji 120V, 240V kana 480Y VAC, uye kusvika ku1000 VDC. MaMCCB: Anogona kushandiswa kune ese ari maviri mashandisirwo emagetsi epasi neakakwira, nematanho anowanzo svika ku600V kana 690V, uye mamwe mamodheru akaongororwa kuti ane magetsi epamusoro.
Muchidimbu
Zvichitaurwa zviri nyore, maMCB circuit breakers zvinhu zvakakosha mumagetsi emazuva ano, zvichipa kuchengetedzeka, nyore, uye kushanda zvakanaka. Kunzwisisa misimboti yekushanda kwayo, mhando dzayo, uye mabhenefiti ayo kunogona kubatsira varidzi vedzimba nemabhizinesi kuita sarudzo dzakakodzera nezvezvinodiwa zvavo zvekudzivirira magetsi. Sezvo tekinoroji ichiramba ichichinja, maMCB circuit breakers acharamba ari musimboti wekuchengetedzwa kwemagetsi, tichiona kuti dzimba dzedu nenzvimbo dzebasa dzakachengetedzwa kubva kunjodzi dzemagetsi.
