Madiki eDunhu reMaputsi: Kuve nechokwadi chekuchengetedzwa kwemagetsi
Munyika yanhasi, magetsi ave chikamu chakakosha muhupenyu hwedu hwezuva nezuva. Kubva pakushandisa magetsi mudzimba dzedu nemahofisi kusvika pakushandisa midziyo nemidziyo yedu, magetsi anoita basa guru mukutibvumira kuita mabasa ezuva nezuva nemazvo. Zvisinei, patinenge tichiita zvekuisa magetsi nemidziyo, kuchengetedzeka ndiko kwakakosha.Madiki ecircuit breakers (MCBs)ndechimwe chezvinhu zvakakosha zvinotichengetedza.
Akadiki kekupwanya dunhu, sezvinoreva zita racho, mudziyo mudiki unoshandiswa kudzivirira macircuit emagetsi kubva pakuwanda kwemagetsi uye macircuit mapfupi. Unoshanda sechinochinja otomatiki, uchikanganisa kufamba kwemagetsi kana paine chikanganiso, nokudaro uchidzivirira kukuvara kwakawanda kwecircuit uye njodzi dzinogona kuitika dzakadai semoto wemagetsi.
Basa guru remadiki ecircuit breakersndeyekupa dziviriro yakavimbika ye overcurrent. Inosanganisira trip mechanism inokonzereswa kana paine overload kana short circuit. trip mechanism iyi yakagadzirirwa kupindura kune current value chaiyo, zvichiita kuti miniature circuit breaker igumbuke nenguva uye ivhure circuit. Izvi zvinobudirira zvinodzivirira overcurrent flow, zvichideredza njodzi yemoto uye electroshock.
MCBinewo zvakanakira zvekushandisa zviri nyore uye zviri nyore. Kusiyana nemafuyuzi echinyakare anoda kutsiviwa mushure mekunge zvikanganiso zvaitika,madiki ecircuit breakersinogona kugadziriswa zviri nyore mushure mekugumburwa. Izvi zvinobvisa kudiwa kwekuchinja zvikamu nguva nenguva, zvichibatsira kuchengetedza nguva nesimba. Pamusoro pezvo,MCBsdziripo mumhando dzakasiyana-siyana dzema "current ratings" uye dzinogona kugadziriswa zvichienderana nezvinodiwa zvedunhu. Kuchinjika uku kunoita kuti dziviriro yakakwana yemagetsi akasiyana-siyana irambe ichishandiswa.
Uyezve,madiki ecircuit breakersdzakagadzirirwa kuti dzikwanise kugadzikana nekuchinja kwetembiricha. Chinhu ichi chinodzibatsira kukurumidza kupindura kana dzikanyanya kupisa nekuda kwekuyerera kwemagetsi kwakawandisa. Nekukanganisa circuit yemagetsi,MCBInodzivirira kuwedzera kwekupisa kunogona kukonzera moto. Hunhu uhwu hunoratidza kukosha kwekushandisa maMCB munzvimbo dzekugara, dzekutengeserana uye dzemaindasitiri uko masisitimu emagetsi anoshandiswa nguva dzose uye zvakanyanya.
Kuisamadiki ecircuit breakersinopa zvakanakira zvakawanda kupfuura masisitimu ekudzivirira emagetsi akajairika. Chinhu chakakosha ndechekuti basa rekubatanidza mafambiro harina sarudzo. Iyi nzira inobvumira MCB kuti ishande pamwe chete nezvimwe zvishandiso zvekudzivirira mudunhu, zvichiita kuti chikamu chakakanganisika chete chive chakaparadzaniswa ukuwo zvimwe zvese zvesisitimu zvichiri kushanda. Iyi nzira yekubatanidza inobatsira kuona chikamu chakakanganisika, zvichiita kuti kudzoreredzwa kwesimba kuve nyore uye nekukurumidza.
Chimwe chakanakira ma "miniature circuit breakers" idhizaini yavo diki uye inochengetedza nzvimbo. Midziyo iyi midiki inotora nzvimbo shoma mu switchboard kana switchboard, zvichisiya nzvimbo yakakura yezvimwe zvikamu zvemagetsi. Nokudaro, ma "miniature circuit breakers" anoshandiswa zvakanyanya munzvimbo dzine nzvimbo shoma, dzakadai senzvimbo dzekugara uye nzvimbo dzemaindasitiri diki.
Kusarudza mhando chaiyo yekadiki kekupwanya dunhuZvakakosha kuti pave nechirongwa chakati.MCBsdziripo, imwe neimwe yakagadzirirwa mwero chaiwo wemazuva ano uye mashandiro. Mhando dzakajairika dzinosanganisira Type B, Type C, uye Type DMCBs, imwe neimwe ichitsanangura huwandu hwemagetsi hwavanogona kubata vasati vagumburwa. Saka, kunzwisisa zvinodiwa nemagetsi uye rudzi rwemidziyo yakabatana kwakakosha pakusarudza MCB yakakodzera.
Muchidimbu,madiki ecircuit breakerszvakakosha zvikuru kuti tive nechokwadi chekuti magetsi akachengeteka muhupenyu hwedu hwezuva nezuva. Dhizaini yayo diki, kushandiswa kwayo kuri nyore uye kuchengetedzwa kwemagetsi kwakavimbika uye kuchengetedzwa kwemasekete mapfupi kunoita kuti ive chinhu chakakosha mune chero sisitimu yemagetsi. Nekumisa masekete emagetsi nenguva, maminiature circuit breakers anodzivirira mamiriro ezvinhu ane njodzi akadai semoto wemagetsi uye anoderedza njodzi yekuvhunduka kwemagetsi. Tichisimbisa kukosha kwekuchengetedza, zvakakosha kuisa nekuchengetedza maminiature circuit breakers mune zvese zvatinoisa zvemagetsi nemidziyo yedu kuti tive nehupenyu hwakanaka isu nevadikanwi vedu.
