KunzwisisaMadiki eDunhu reMaputsi: Gwaro Rakazara
MaMinitary circuit breakers (MCBs) zvinhu zvakakosha mukuchengetedza nekutarisira magetsi. MaMCBs anodzivirira macircuit emagetsi kubva pakuwanda kwemagetsi uye mashort circuit, akakosha pakuona kuchengetedzeka nekuvimbika kwemasystem emagetsi munzvimbo dzekugara, dzebhizinesi, uye dzemaindasitiri. Chinyorwa chino chichaongorora mashandiro, mabhenefiti, uye mashandisirwo emaminiary circuit breakers, zvichipa kunzwisisa kwakazara kwekukosha kwawo mumidziyo yemagetsi yemazuva ano.
Chii chinonzi miniature circuit breaker?
A kamuchina kekupwanya dunhu kadiki (MCB)iswichi inodzima magetsi mudunhu kana yaona chimwe chinhu chisina kujairika, senge overload kana short circuit. Kusiyana nemafuse echinyakare, ayo anofanira kutsiviwa mushure mekunge aputika, maMCB anogona kudzoserwa patsva mushure mekugumburwa, zvichiita kuti ave sarudzo iri nyore uye inoshanda yekudzivirira magetsi mudunhu. MaMCB anowanzo kuve madiki uye ari nyore kuisa mumabhodhi ekuparadzira uye maswitchboard.
Ma "miniature circuit breakers" anoshanda sei?
Kushanda kwemuchina we "miniature circuit breaker" kunoenderana nemaitiro maviri makuru: kupisa kunokanganisa uye magnetic kunokanganisa.
1. Rwendo rwekupisa:
Iyi nzira inoshandisa bimetallic strip iyo inopisa uye inokotama kana magetsi akakwira zvakanyanya. Kana magetsi adarika simba rakatarwa reminiature circuit breaker, strip yacho inokotama zvakakwana kuti itange switch, ichibvisa simba.
2. Rwendo rweMagineti:
Iyi nzira inofambiswa nekuwedzera kwesimba remagetsi kamwe kamwe (senge kunokonzerwa ne short circuit). Iyo solenoid inogadzira simba remagineti, ichidhonza lever uye ichipwanya circuit ipapo ipapo.
Maitiro maviri aya anoita kuti MCB irambe yakachengetedzwa kubva pakuwanda zvishoma nezvishoma uye kukundikana kamwe kamwe, zvichiita kuti ive sarudzo inoshandiswa zvakasiyana-siyana pakushandisa kwakasiyana-siyana.
Mabhenefiti eMinitary Circuit Breakers
- Inogona kugadziriswazve:Kusiyana nemafuse anoda kutsiviwa mushure mekukundikana, maMCB anogona kugadziriswa zviri nyore, zvichideredza nguva yekushanda uye mari yekugadzirisa.
- Dhizaini Yakabatana:MaMCB akagadzirwa kuti atore nzvimbo shoma, zvichibvumira kushandiswa kwemapaneru emagetsi nemabhodhi ekuparadzira zvinhu zviri nani.
- Kururama:MaMCB anopa dziviriro chaiyo nekugumburwa pamatanho chaiwo emagetsi, zvichiita kuti dunhu rakakanganiswa chete ribviswe panguva yekutadza.
- Kuchengetedzwa Kwakawedzerwa:Nekukurumidza kumisa kufamba kwemagetsi panguva yekukanganisa, maMCB anobatsira kudzivirira moto wemagetsi nekukuvara kwemidziyo, nokudaro zvichivandudza kuchengetedzeka kwese.
- Zviri nyore kushandisa:MaMCB anowanzo ratidza kana mudziyo wacho wakavhurika kana kuti wakavharika, zvichiita kuti zvive nyore kuti vashandisi vatarise mamiriro awo.
Kushandiswa kweMinitary Circuit Breakers
Maminiature circuit breakers anoshandiswa mumhando dzakasiyana-siyana dzemashandisirwo, kusanganisira:
Wiring dzemumba:MaMCB anowanzoiswa mudzimba kudzivirira magetsi nemagetsi, zvichiita kuti midziyo yemumba nemidziyo zvive zvakachengeteka.
Zvivako zveMabhizimisi:Munzvimbo dzekutengeserana, maMCB anodzivirira kuwandisa kwemagetsi, achidzivirira michina inobatwa nenjodzi uye achivimbisa kushanda pasina kukanganiswa.
Mashandisirwo Emaindasitiri:MaMCB akakosha munzvimbo dzemaindasitiri, uko anodzivirira michina nemidziyo kubva kumatambudziko emagetsi, nokudaro zvichivandudza kushanda zvakanaka uye kuchengetedzeka.
Masisitimu Esimba Rinodzokororwa:Nekuwedzera kwesimba rezuva nemamwe magetsi anogona kushandiswazve, maMCB ari kushandiswa zvakanyanya muma solar inverters nema bhatiri ekugadzirisa mabhatiri kudzivirira kutadza kushanda zvakanaka.
Mukupedzisa
MaMinitary circuit breakers (MCBs) anoita basa rakakosha mumagetsi emazuva ano, achipa dziviriro yakakosha uye dziviriro yepfupi. Hunhu hwawo hwekugadzirisazve, dhizaini diki, uye kunyatsoita zvinhu zvinoita kuti ave sarudzo yepamusoro kune ese ari maviri ekushandisa mudzimba nemabhizimisi. Sezvo masisitimu emagetsi achiramba achichinja, kukosha kwedziviriro yedunhu yakavimbika kucharamba kuchikura, uye basa reMCB mukuona kuchengetedzeka uye kushanda zvakanaka kwehupenyu hwedu hwezuva nezuva richawedzera. Kunzwisisa mashandiro avo nemabhenefiti kwakakosha kune chero ani zvake anobatanidzwa mukuisa kana kugadzirisa magetsi, zvichiita kuti MCB ive chikamu chakakosha chekuchengetedzwa kwemagetsi emazuva ano.
