KunzwisisaMaputsi edunhu: Zvishandiso Zvakakosha Zvekuchengetedza MuMasisitimu Emagetsi
Macircuit breaker zvinhu zvakakosha mumasystem emagetsi, zvinoshanda semidziyo yekudzivirira kukuvara kunokonzerwa nekuwanda kwemagetsi uye mashort circuit. Macircuit breaker akagadzirwa kuti adzivise kufamba kwemagetsi otomatiki kana paine chikanganiso, nokudaro achivimbisa kuchengetedzeka kwesystem yemagetsi nevashandisi vayo. Chinyorwa chino chichatarisa zvakadzama mashandiro, mhando, uye kukosha kwemacircuit breaker mumidziyo yemagetsi yemazuva ano.
Basa guru remuchina wekupwanya magetsi nderekuvhura nekuvhara dunhu remagetsi. Kusiyana nemafuyusi anofanira kutsiviwa mushure mekunge aputika, macircuit breaker anogona kudzoserwa patsva mushure mekunge adonha, zvichiita kuti ave sarudzo iri nyore uye inoshanda yekudzivirira magetsi. Kana paine dambudziko remagetsi rakadai se short circuit kana overload, muchina wekupwanya magetsi unoona magetsi asina kujairika uye unocheka dunhu, zvichidzivirira njodzi dzakadai semoto wemagetsi kana kukuvara kwemidziyo.
Kune mhando dzakawanda dzemacircuit breaker, imwe neimwe yakagadzirirwa mashandisirwo chaiwo uye nharaunda. Mhando dzakajairika dzinosanganisira:
1. Chinopwanya Dunhu Chidiki (MCB): Rudzi urwu rwecircuit breaker runoshandiswa muzvivakwa zvekugara uye zvemabhizinesi kudzivirira kubva mukuwanda kwemagetsi uye mashort circuit. Maminiature circuit breaker ane voltage yakaderera uye anowanzo shandiswa mumidziyo yekuparadzira magetsi.
2. Chinopwanya Dunhu Renguva Dzekare (RCCB): Aya macircuit breaker, anozivikanwawo seResidual Current Devices (RCD), anodzivirira kubva pakukanganisa kwepasi nekuona kusawirirana kwemagetsi. Akakosha pakudzivirira kuvhunduka kwemagetsi uye anowanzo shandiswa munzvimbo dzine mvura dzakadai sedzimba dzekugezera nekicheni.
3. Molded Case Circuit Breaker (MCCB): Rudzi urwu rwecircuit breaker runoshandiswa mumaindasitiri uye runogona kubata ma current ratings akakwira. MCCBs dzinopa overload, short circuit, uye ground fault protection uye dzakakodzera masisitimu makuru emagetsi.
4. Maputsi emhepo (ACB): MaACB akagadzirwa kuti ashandiswe mumagetsi ane simba rakawanda uye anoshandiswa muzviteshi zvemagetsi uye mumafekitori makuru emaindasitiri. Anogona kubata magetsi akawanda uye kudzivirira zvikanganiso zvemagetsi.
Kukosha kwemacircuit breaker hakufanirwe kutaurwa zvakanyanya. Anoita basa rakakosha mukuona kuchengetedzeka uye kuvimbika kwemasystem emagetsi. Nekudzivirira kuwandisa kwemagetsi nema short circuit, macircuit breaker anobatsira kudzivirira kwete chete zvivakwa zvemagetsi, asiwo michina nemidziyo yakabatana nazvo. Dziviriro iyi inonyanya kukosha munzvimbo dzekutengeserana nemaindasitiri, uko kutadza kwemidziyo kunogona kukonzera kurasikirwa kukuru kwemari nenjodzi dzekuchengetedza.
Kuwedzera pamabasa avo ekudzivirira, macircuit breaker anovandudza kushanda zvakanaka kwemasystem emagetsi. Nekutarisira zvakachengeteka mitoro yemagetsi, macircuit breaker anogonesa kubatanidzwa kwesimba rinogona kushandiswazve senge solar panels nema wind turbines mugrid. Kuchinjika uku kwakakosha sezvo nyika iri kufambira mberi kune mhinduro dzesimba dzinogara kwenguva refu.
Kugadziriswa nekuongororwa kwemacircuit breakers nguva nenguva kwakakosha kuti ive nechokwadi chekuti akavimbika uye anoshanda zvakanaka. Nyanzvi dzemagetsi dzinokurudzira kuongororwa nguva nenguva kuti dzione zviratidzo zvekusakara, ngura, kana kusashanda zvakanaka. Maitiro aya anobatsira kuona matambudziko angangoitika asati asvika pamatambudziko akakomba.
Muchidimbu, macircuit breaker mudziyo unokosha wekuchengetedza mumagetsi, uchidzivirira overload uye short circuit. Kune mhando dzakawanda dzemacircuit breaker, dzakakodzera kushandiswa kwakasiyana, zvichiita kuti michina yemagetsi igare yakachengeteka uye ichishanda zvakanaka. Sezvo tekinoroji ichiramba ichikura, macircuit breaker acharamba ari chikamu chakakosha mukuchengetedza zvivakwa zvemagetsi, zvichiita kuti zvive mudziyo unokosha kune vashandisi vedzimba nemaindasitiri. Kunzwisisa basa nekukosha kwemacircuit breaker chinhu chakakosha pakuchengetedza nzvimbo yemagetsi yakachengeteka uye yakavimbika.
