Title: Kunzwisisa Kukosha kweEarth Leakage Circuit Breakers
introduce
Munyika yanhasi umo kuchengetedzwa kwemagetsi kwakakosha,zvakasara zvazvino zvemagetsi mabreaker (RCCBs)kuita basa rinokosha mukuchengetedza kuchengeteka kweupenyu hwevanhu nezvinhu.Nepo vazhinji vangave vasina kujairana neshoko iri,RCBsinhengo inokosha yegadziriro ipi neipi yemagetsi.Ichi chinyorwa chine chinangwa chekujekesa kukosha kwezvakasara zvemadunhu edunhu, basa ravo uye zvakanakira mukudzivirira kuiswa kwemagetsi.
Ndima 1: Chii chinonzi anpasi leakage circuit breaker?
A saridual current circuit breaker, inowanzonzi anRCCB, chinhu chemagetsi chakagadzirirwa kuchengetedza vanhu uye kuiswa kwemagetsi kubva kumagetsi emagetsi uye njodzi dzemoto dzinokonzerwa nekubuda kwemagetsi.Zvichitaurwa zviri nyore, anRCCBinotarisisa ikozvino mudunhu uye inofambisa dunhu kana ikaona kusaenzana kwazvino.Kusaenzana uku kunogona kukonzerwa nekudonha kwemvura, kutadza kwekudzivirira, kana kuonana zvakananga nemakondakita mhenyu.
Ndima 2: Inoita sei anpasi leakage circuit breaker basa?
Leakage current circuit breaker ane mafesitori emazuva ano anogara achiyera zvazvino kuburikidza nevanorarama uye vasina kwavakarerekera.Chero nguva paine musiyano pakati peiyo yekuisa ikozvino uye yekudzoka ikozvino, inoratidza kuvuza kana kukanganisa.TheRCCBinoona mutsauko uyu uye inokurumidza kufambisa dunhu, ichicheka simba kudzivirira imwe kukuvara.
Ndima yechitatu: zvakanakira leakage circuit breakers
Kuisa pasi leakage circuit breaker kune akawanda mabhenefiti maererano nekuchengetedza nekudzivirira.Kutanga, vanogona kuderedza zvakanyanya njodzi yekuvhundutsa kwemagetsi nekuona kusaenzana kudiki kudunhu uye kukanganisa simba munguva.Chepiri,RCBszvakakosha pakudzivirira moto unokonzerwa nekukanganisa kwemagetsi, sezvo ivo vanopindura nekukurumidza kune zvisina kujairika magetsi emagetsi, kuderedza mukana wekupisa uye arcing.
Uye zvakare, kuvuza kwedunhu mabreaker anogona kukurumidza kudzima magetsi muchiitiko chekudonha kana kutadza, ichipa imwe dziviriro yemidziyo nemidziyo.Nekuita kudaro, midziyo yakakosha inogona kudzivirirwa nekudzivirirwa kubva pakukuvadza kunogona kuitika, zvichikonzera kuchengetedza mari uye hupenyu hurefu.
Ndima 4: Mhando dzepasi rinodonhedza masekete breakers
Kune mhando mbiri huru dzeRCBs: Rudzi AC uye Rudzi rweA. AC mhando RCCBs inowanzoshandiswa munzvimbo dzekugara kuti ipe dziviriro kubva kune sinusoidal alternating currents.Aya maRCCB akanakira kuchengetedzwa kubva kune zvakajairika masosi ekudonha senge miwiring, waya dzakakuvadzwa, uye kutadza kwemidziyo.
Type A RCCBs, kune rumwe rutivi, dzakanyanya kufambira mberi uye dzinopa imwe dziviriro nekubatanidza alternating ikozvino uye pulsating yakananga ikozvino (DC).Aya maRCCB anowanzo kuisirwa mune mamwe mabasa ehunyanzvi akadai sezvipatara, nzvimbo dzemaindasitiri uye uko kunoshandiswa zvakanyanya kusimba zvemagetsi michina.Type A RCCBs inova nechokwadi chekuchengetedzwa kwakazara kubva kune AC uye DC kukanganisa pasina chero nzvimbo yekukanganisa.
Ndima 5: Kukosha kwekugara nguva dzoseRCCBkuedza uye kugadzirisa
Nepo zvakasara zvazvino zvinotyora zvedunhu zvisina mubvunzo zvakakosha kuchengetedzeka kwemagetsi, zvakakoshawo kuti unzwisise kukosha kwekugara uchiyedza uye kugadzirisa.Sezvimwe chero mudziyo wemagetsi,RCBszera nekufamba kwenguva, kuderedza kushanda kwavo kana kukundikana.Naizvozvo, kuyedzwa nguva dzose uye kugadzirisa kunofanirwa kurongwa kuti ive nechokwadi chekutiRCCBiri muhurongwa hwepamusoro uye inodzivirira chero njodzi dzinogona kuitika dzemagetsi.
Ndima 6: Mhedziso
Mukupedzisa, zvakasara zvemazuva ano zvinoputika chikamu chinokosha chemazuva ano emagetsi emagetsi, achipa kudzivirirwa kwakasimba kubva kumagetsi emagetsi uye njodzi dzemoto.RCCB inogona kuona kusaenzana kwazvino uye kukanganisa dunhu munguva, iyo inogona kuvandudza zvakanyanya kuchengetedzwa kwemagetsi kushandiswa uye kuchengetedza hupenyu nemidziyo.Nekudyara muRCCBs emhando yepamusoro, kusarudza mhando chaiyo yechishandiso chega chega, uye kugara tichiyedza nekugadzirisa, tese tinokwanisa kugadzira nzvimbo yakachengeteka yemagetsi isu nezvizvarwa zvinotevera.
