Munyaya dzekuchengetedzwa kwemagetsi,maresidual current circuit breakers (RCCBs)inoita basa guru mukudzivirira vanhu nepfuma kubva kunjodzi dzemagetsi. Midziyo iyi yakagadzirirwa kudzivirira kuvhunduka kwemagetsi uye kuderedza njodzi yemoto wemagetsi unokonzerwa nekukanganisa kwepasi. Chinyorwa chino chichakurukura zvakadzama nezvebasa, kukosha, uye mashandisirwo eRCCBs.
Chii chinonzi residual current operated circuit breaker (RCCB)?
Chinobvisa magetsi (RCCB) chishandiso chemagetsi chinobvisa magetsi kana chikaona kusawirirana pakati pemagetsi aripo (phase) neaya asina kusimba. Kusawirirana uku kunogona kukonzerwa nekutadza, senge munhu akabata conductor aripo netsaona, kana kukanganisa kwemagetsi kunoita kuti magetsi adonhe pasi. RCCB inoramba ichitarisa magetsi ari mudunhu, uye kana ikaona musiyano wemagetsi (kazhinji 30 mA yekudzivirira munhu), inogumbura uye inobvisa magetsi mukati memamiliseconds.
Ndeipi musimboti wekushanda kweresidual current operated circuit breaker (RCCB)?
Chinobvisa magetsi chinoshandiswa nemagetsi (RCCB) chinoshanda nepfungwa ye differential current. Chine iron core nema coil maviri: rimwe rewaya iri mhenyu uye rimwe rewaya isina kusimba. Mumamiriro ezvinhu akajairwa, magetsi ari kufamba nepakati pema conductor maviri akaenzana, uye ma magnetic fields anokonzerwa nema coils anodzimana. Zvisinei, kana leakage current iripo, chiyero ichi chinokanganiswa, zvichikonzera musiyano musimba rema magnetic field. Kusawirirana uku kunoita kuti RCCB iputsike, zvichibvisa circuit uye kudzivirira njodzi dzinogona kuitika.
Kukosha kweVatambi veDunhu Vanoshandiswa Nenguva Dzose Vari Kusara
Kukosha kwemaresidual current operated circuit breakers (RCCBs) hakufanirwe kufuratirwa. Iwo mutsetse wakakosha wekudzivirira kubva mukuvhunduka kwemagetsi, izvo zvinogona kukonzera kukuvara kwakanyanya kana kutofa. Zvichienderana nezvinodiwa zvekuchengetedza, zvivakwa zvakawanda zvekugara nezvemabhizinesi, kunyanya nzvimbo dzine mvura (senge dzimba dzekugezera nemakicheni), zvinofanirwa kunge zvine maRCCB. MaRCCB anogona kukurumidza kupindura kumatambudziko emagetsi, zvichivandudza zvakanyanya kuchengetedzeka kwekuisa magetsi.
Pamusoro pezvo, maresidual current operated circuit breakers (RCCBs) anobatsira kudzivirira moto wemagetsi. Kukanganisika kwemutsetse, kukuvara kweinsulation, kana zvikanganiso zvemagetsi zvinogona kukonzera kupisa zvakanyanya uye mazhenje, izvo zvinogona kubatidza zvinhu zvinobvira moto. MaRCCB anogona kubvisa dunhu ipapo ipapo kana paine zvikanganiso, nokudaro achideredza njodzi yekubvira moto uye achidzivirira hupenyu nepfuma.
Kushandiswa kweResidual Current Operated Circuit Breakers
MaResidual current operated circuit breakers (RCCBs) anoshandiswa zvakanyanya munzvimbo dzakasiyana-siyana, kusanganisira dzekugara, dzekutengeserana, uye dzemaindasitiri. Muzvivakwa zvekugara, anowanzoiswa pane main distribution panel kudzivirira circuits dzese. Muzvivakwa zvemabhizinesi, maRCCB akakosha pakudzivirira michina uye kuona kuchengetedzeka kwevashandi nevatengi. Munzvimbo dzemaindasitiri, kunyanya uko michina inorema inoshandiswa, maRCCB akakosha pakudzivirira vashandi kubva kunjodzi dzemagetsi.
Uyezve, maresidual current operated circuit breakers (RCCBs) anogona kusanganiswa nezvimwe zvishandiso zvekudzivirira, zvakaita semaminiature circuit breakers (MCBs) uye ma surge protectors (SPDs), kugadzira system yakakwana yekuchengetedza magetsi. Kusanganiswa uku hakungovimbisi chete kuonekwa nekugadzirisa zvikanganiso zvepasi asiwo kugadzirisa zvinobudirira kuwanda kwemagetsi nekuwedzera kwemagetsi.
Chii chinoita kuti RCD breaker igumbuke?
Maseketi akawandisa, kupinda kwehunyoro, waya dzakakuvara, kubuda kwemvura pasi, uye midziyo isina kunaka ndezvimwe zvezvikonzero zvikuru zvinoita kuti RCD iparare. Kunzwisisa zvinhu izvi kunogona kukubatsira kuona nekugadzirisa dambudziko nekukurumidza kuti uve nechokwadi chekuti magetsi akachengeteka mumba mako.
Muchidimbu
Muchidimbu, maResidual current circuit breakers (RCCBs) chinhu chakakosha mukuchengetedza magetsi kwemazuva ano. Anoona uye anopindura kusawirirana kwemagetsi, zvichishanda sezvishandiso zvakakosha zvekudzivirira kuvhunduka kwemagetsi nemoto wemagetsi. Sezvo hupenyu hwedu hwezuva nezuva huchiwedzera kuvimba nemagetsi, kunzwisisa nekushandisa maRCCB kwakakosha pakuona kuchengetedzeka mudzimba, munzvimbo dzebasa, nedzimwe nzvimbo. Kuisa mari muRCCB dzemhando yepamusoro uye kuona kuti dzakaiswa zvakanaka kunopa rugare rwepfungwa uye zvinobudirira kudzivirira kuvhunduka kwemagetsi netsaona.
