A low-voltage circuit breaker imagetsi emagetsi anoshandiswa kutakura uye kuputsa redunhu ikozvino.Zvinoenderana netsanangudzo yeiyo yenyika chiyero GB14048.2, yakaderera-voltage maseketi anotyora anogona kupatsanurwa kuita akaumbwa makesi edunhu mabreaker uye furemu redunhu mabreak.Pakati pavo, iyo yakaumbwa kesi yedunhu inotyora inoreva dunhu rinotyora iro goko rakagadzirwa neyakaumbwa insulating zvinhu, uye kazhinji inoshandisa mweya searc yekudzima svikiro, saka inowanzonzi otomatiki mhepo switch.
Chipopori chemhepo (air circuit breaker) zvinoreva muputsi wedunhu uyo macontacts anovhurwa nekuvharwa mumhepo pamhepo.Kusiyana nemhepo inochinja, vacuum circuit breaker dzinoitwa nekuvhura nekuvhara madhiri mune yakakwira vacuum chubhu.Izvo zvinofanirwa kucherechedzwa kuti kunyangwe yakaderera-voltage yakaumbwa kesi yedunhu mabreaker inowanzonzi otomatiki mhepo switch, switch uye wedunhu mabreaks ari chaiwo maviri akasiyana pfungwa.
Low-voltage circuit breaker anowanzo shandiswa kutakura uye kutyora yazvino yedunhu, uye anogona kupatsanurwa kuita marudzi maviri: akaumbwa makesi edunhu mabhureki uye furemu anopwanya edunhu.Iyo molded kesi circuit breaker iri zvakare mhepo inotyora mhepo, inoshandisa mweya searc yekudzima svikiro.Molded case circuit breakers kazhinji ine diki diki uye yakatemerwa yekutyora ikozvino pane furemu redunhu mabreak, saka anodzivirirwa nekesi yepurasitiki.Mafuremu edunhu anopwanya ane hukuru hukuru uye yakakwirira yakayerwa kupwanya mafungu, kazhinji haadi akavharirwa epurasitiki, uye zvese zvikamu zvakaiswa pasimbi.Panyaya yedunhu pfupi kana yakakwira ikozvino, muparadzi wedunhu ane yakanaka arc yekudzima kugona uye anogona kungozvitsika, saka inowanzoshandiswa pakushandisa midziyo yemagetsi yakadai sekutadza kwemagetsi, kutapurirana simba, nekudzima nekudzima mutoro.
Kusarudzwa kwekuchinja kwemhepo kunoda kugadziriswa maererano nemamiriro chaiwo.Zvinokurudzirwa kuti zvinotevera zvinhu zvinofanirwa kutariswa kana uchisarudza mhepo switch:
1.Sarudza maererano nepamusoro pesimba rekushandisa reimba kuti udzivise kugumburwa kakawanda nekuda kwemutoro unopfuura ikozvino.
2. Sarudza akasiyana mapfupi edunhu mapfupi kana ma switch emhepo zvinoenderana nesimba remagetsi akasiyana siyana kudzivirira kugumburwa nekuda kwekunyanyisa ikozvino panguva yekutanga.
3.Sarudza 1P leakage vadziviriri mumatunhu ese ebazi kuti uvandudze kuchengetedzwa kwemidziyo yemagetsi.
4.Partitioning uye branching, nzvimbo dzakasiyana-siyana dzinogona kugoverwa maererano nepasi kana midziyo yemagetsi, iyo iri nyore pakugadzirisa nekugadzirisa.Kazhinji, kusarudzwa kwemhepo yekushandura kunoda kuitwa maererano nemamiriro ezvinhu chaiwo.Kunyanya, mhando, simba, huwandu uye zvimwe zvinhu zvemidziyo yemagetsi zvinofanirwa kutariswa kuti ive nechokwadi chekugadzikana uye kuchengetedzeka kwemagetsi ekushandisa.
Mukuwedzera kune zvataurwa pamusoro apa, zvinhu zvinotevera zvinofanirawo kutariswa paunenge uchitenga shanduko yemhepo: 6. Shandisa nzvimbo: Ikozvino yakarongwa yemhepo inoputika inobatanidzawo nekupisa kwenzvimbo yekushandisa.Kana iyo ambient tembiricha yakakwira, iyo yakayerwa ikozvino yeiyo air breaker inodonha, saka iyo air breaker inofanirwa kusarudzwa zvinoenderana neiyo chaiyo yekushandisa nharaunda.7. Kugara kwenguva refu: Kushandura kwemhepo kunowanzoshanda nguva dzose, saka zvakakosha kusarudza chigadzirwa chine hutano hwakanaka uye kusimba kwakasimba kuti urege kudzivirira kakawanda kuchinjwa nekugadzirisa.8. Kuzivikanwa kwechiratidzo: Paunenge uchitenga ma compressor emhepo, unofanirwa kusarudza izvo zvigadzirwa zvemhando ine mukurumbira wepamusoro uye mukurumbira wakanaka kuti uve nechokwadi chemhando uye mushure mekutengesa-basa.9. Chimiro chechimiro: Pasi pechigadziro chimwechete chemagetsi ekugadzirisa, zvinokurudzirwa kushandisa shanduro imwechete yekushandura mhepo kuti udzivise kuvhiringidzika uye kusagadzikana panguva yekushandiswa nekugadzirisa.10. Kureruka kwekuisa uye kugadzirisa: Pakusarudza chinja chemhepo, kuve nyore kwekuisa uye kugadzirisa kunofanira
