Maputsi edunhu: Magamba Asingaimbirwi Ekuchengetedza Magetsi
Munyika yemagetsi, macircuit breaker anoita basa rakakosha mukuona kuchengetedzeka uye kushanda kwese kwekuisa. Ichi chishandiso chiri nyore asi chine hungwaru chakagadzirirwa kudzivirira macircuit kubva mukukuvadzwa kunokonzerwa ne overcurrent uye short circuits. Macircuit breaker anoshanda senzira isina njodzi, achikanganisa kufamba kwemagetsi kana mamiriro asina kunaka akaonekwa, nokudaro achidzivirira njodzi dzinogona kuitika dzakadai semoto wemagetsi uye kukuvara kwemidziyo.
Nheyo huru yecircuit breaker ndeyekuvhura circuit yega kana magetsi adarika chiyero chakati. Izvi zvinoitwa kuburikidza nekushandisa nzira inoshandisa bimetallic strip kana electromagnet kupwanya circuit breaker kana magetsi akawandisa aonekwa. Kana circuit yangomiswa, circuit breaker inogona kudzoserwa patsva nemaoko kuti idzorere kuyerera, zvichiita kuti ive mudziyo wekuchengetedza unogona kushandiswazve.
Kune mhando dzakasiyana dzemacircuit breaker akagadzirirwa kushandiswa kwakasiyana-siyana, kusanganisira nzvimbo dzekugara, dzekutengeserana, uye dzemaindasitiri. Muzvivakwa zvekugara, maminiature circuit breaker (MCBs) anowanzo shandiswa kuchengetedza macircuit ega ega, akadai seaya emwenje, midziyo, uye masoketi. MaMCB aya madiki uye anogona kuiswa nyore nyore mumapaneru emagetsi, zvichipa nzira iri nyore uye inoshanda yekudzivirira sisitimu yemagetsi yemba.
Kunzvimbo dzekutengeserana nemaindasitiri, ma "large circuit breakers" akadai se "molded case circuit breakers" (MCCB) uye "air circuit breakers" (ACB) anoshandiswa kudzivirira ma "voltage" akakwira uye ma "current circuit". Anokwanisa kubata mitoro mikuru yemagetsi, aya ma "heavy duty circuit breakers" akakosha pakuona kuchengetedzeka uye kuvimbika kwema "complex electrical systems" muzvivakwa zvemabhizinesi, mafekitori nema "power plants".
Chimwe chezvakanakira zvikuru zvemacircuit breaker kugona kwawo kupindura nekukurumidza uye nemazvo mumamiriro ekunze akawandisa, nokudaro achideredza njodzi yetsaona dzemagetsi. Kusiyana nemafuse, ayo anoda kutsiviwa mushure mekushanda, macircuit breaker anogona kudzorerwa patsva, zvichiita kuti ave mhinduro iri nyore uye isingadhuri yekudzivirira macircuit.
Kuwedzera pabasa rawo guru rekudzivirira overcurrent, macircuit breaker emazuva ano ane zvinhu zvepamusoro zvakaita sekudzivirira ground fault, arc fault detection, uye remote monitoring. Izvi zvimwe zvinhu zvinowedzera kuchengetedzeka uye kushanda kwemasystem emagetsi, zvichiita kuti macircuit breaker ave chikamu chakakosha chezvivakwa zvemagetsi zvemazuva ano.
Sezvo tekinoroji ichiramba ichifambira mberi, kugadzirwa kwema "smart circuit breakers" kuri kuwedzerawo simba. Ma "smart circuit breakers" ane masensa akavakirwa mukati uye kugona kutaurirana kunoita kuti akwanise kupa data renguva chaiyo pamusoro pemagetsi nemamiriro esystem. Izvi zvinogonesa kugadzirisa nekukurumidza uye kugadzirisa matambudziko ari kure, zvichiwedzera kuvimbika uye kushanda zvakanaka kwekuisa magetsi.
Zvose pamwe chete, macircuit breaker angasawana kutariswa nguva dzose, asi hapana mubvunzo kuti ndiwo chinhu chakakosha mukuona kuti magetsi akachengeteka uye akavimbika. Kubva kudzimba kusvika kumaindasitiri, macircuit breaker anoita basa rakakosha mukudzivirira njodzi dzemagetsi uye kuchengetedza kuchengetedzwa kwezvivakwa zvemagetsi. Sezvo kudiwa kwemhinduro dzemagetsi dzinoshandisa simba shoma uye dzakangwara kuri kuramba kuchikura, kukosha kwemacircuit breaker mukuchengetedza masisitimu emagetsi kuchaonekwa zvakanyanya mumakore anotevera.
