Kunyura Zvakadzama muResidual Current Operated Circuit Breaker (RCBO)

Mumagetsi emazuva ano ane magetsi mashoma, kuchengetedzeka uye kuvimbika ndizvo zvinonyanya kukosha.Chinosara Chemagetsi Chinoshanda Nenguva Dzose (RCBO) chishandiso chakakosha chekudzivirira chakagadzirirwa kudzivirira njodzi dzemagetsi dzakadai sekuvhunduka kwemagetsi nemoto zvinokonzerwa nekutadza kwemagetsi. Nekubatanidza dziviriro yemagetsi akawandisa, short-circuit, uye residual current, RCBO inopa kuchengetedzeka kwakakwana kune akasiyana mashandisirwo. Muchinyorwa chino, tichaongorora zvinhu zvakakosha uye hunyanzvi hweRCBO nebasa rayo mukuchengetedza masisitimu emagetsi.

Kushanda Kwakakosha kweRCBO

RCBO inobatanidza nzira dzakawanda dzekudzivirira mumudziyo mumwe chete. Basa rayo guru nderekuona kuwanda kwemagetsi, mapfupi, kana marestial currents (leakage currents) uye kubvisa magetsi ipapo ipapo kudzivirira kukuvara kunogona kuitika kuvanhu nezvinhu. Izvi zvinoita kuti maRCBO akwanise kushandiswa zvakasiyana-siyana, sezvo achishandiswa munzvimbo dzakasiyana-siyana, kubva pakuisa dzimba kusvika kunzvimbo dzekutengeserana nemaindasitiri.

Magadzirirwo Akakosha Ehunyanzvi uye Zvimiro

1. Rating Current Range: MaRCBO anouya nenzira dzakasiyana-siyana dze current dzakatarwa kuti dzikwane maapplication akasiyana. Mamodheru akafanana neCMTB1LE-32 neCMTB1LE-63 anofukidza current range kubva pa3A kusvika pa63A. Kunyanya, CMTB1LE-32 inowanikwa mu ratings dze3A, 6A, 10A, 16A, 20A, 25A, uye 32A, zvichiita kuti ive yakanaka kune light load situations kusvika pakati nepakati. CMTB1LE-63, kune rumwe rutivi, yakagadzirirwa kutakura zvinhu zvakawanda, ne ratings dzemazuva ano dze40A, 50A, uye 63A, dzakanakira maapplication ane simba guru.

2. Kugona Kuputsa Magetsi Nemasekonzi Mapfupi: RCBO dzakagadzirirwa kumisa kufamba kwemagetsi zvakachengeteka kana paine circuit pfupi. Modhi yeCMTB1LE-32 ine kugona kwekuputsa kwe6000A, izvo zvinoita kuti ikwanise kudzima magetsi nekukurumidza kana magetsi akawandisa achiyerera. CMTB1LE-63 inopa kugona kwakasiyana kwekuputsa zvichienderana nechiyero chemagetsi: 6000A pa40A uye 4500A pa50A ne63A. Kugona uku kwakasimba kunoita kuti RCBO ive yakavimbika mukudzivirira kukuvara kwemidziyo yemagetsi panguva yekutadza.

3. Magadzirirwo ePole: RCBO inopa kuchinjika nemaitiro epole, kusanganisira sarudzo dze1P+N, 2P, 3P+N, uye 4P, zvichiita kuti dzigone kuchinjika kune ese ari maviri masisitimu emagetsi echikamu chimwe chete uye matatu. Kuchinjika uku kunobvumira kushandiswa kwakasiyana-siyana ukuwo kuchivimbisa kuti maseketi akachengetedzwa kubva pakuzara, mashort circuits, uye maresidual currents.

4. Mhando dzeDziviriro yeMagetsi Akasara: Kune mhando mbiri dzedziviriro yemagetsi akasara anopiwa neRCBO—Rudzi C neRudzi D, dzakagadzirirwa magetsi akarongwa pakati pe3A ne63A. Rudzi C rwakakodzera magetsi akajairwa, nepo Rudzi D rwakagadzirirwa magetsi ane simba guru kana kuti anotakura simba, akadai semamota kana michina yeindasitiri. Izvi zvinobvumira RCBO kubata mhando dzakasiyana dzemagetsi zvinobudirira, kudzivirira kuwandisa kwemasisitimu kana kukuvara.

5. Kunzwa Kwemagetsi Asina Kushanda: MaRCBO anopa mwero wakasiyana wekunzwa kwemagetsi akasara, inova ndiyo nzira huru yekudzivirira kubuda kwemvura. Mamagetsi anoshanda akasara (IΔn) anowanzo kuwanikwa mumhando dzakadai se30mA, 50mA, uye 100mA, zvichiita kuti mudziyo ugone kuona kubuda kwemvura uye kubvisa simba kana zvichidikanwa. Pamusoro pezvo, magetsi asingashande (IΔno) asara (15mA, 25mA, uye 50mA) anopa kunyatsojeka mukudzivirira kugumburwa kusingadiwe uku uchichengetedza kuchengetedzeka.

6. Nguva Yekukurumidza Kupindura: Kana paine dambudziko remagetsi, maRCBO anoita pakarepo, nenguva yekugumburwa iri pasi pemasekondi 0.1. Mhinduro iyi inokurumidza inoderedza njodzi yekukuvara kwakanyanya kana tsaona, zvichipa dziviriro yakavimbika pamhando dzakasiyana dzemagetsi.

Zvikumbiro zveRCBO

MaRCBO anoshandiswa zvakanyanya mudzimba, mumabhizinesi, uye mumaindasitiri masisitimu ekugovera magetsi mashoma. Maitiro avo ekudzivirira akabatanidzwa anoita kuti ave akakosha munzvimbo dzemagetsi dzemazuva ano, uko mitoro yakasiyana-siyana uye yakaoma inowanikwa.

Pakushandisa dzimba, RCBO inoona kuti midziyo yemagetsi yemumba yakachengetedzwa kubva pakubuda kwemvura, zvichidzivirira njodzi dzemagetsi. Munzvimbo dzekutengeserana, RCBO inodzivirira midziyo yakakosha uye zvivakwa kubva kumatambudziko emagetsi, ichivimbisa kuti bhizinesi rinoenderera mberi. Mukushandiswa kwemaindasitiri, kunyanya uko midziyo yakaita semota nemichina inorema inoshandiswa, Type D RCBO inopa dziviriro yepamusoro kubva kumafungu emvura anopinda zvakanyanya anogona kuitika nemitoro yakadaro inductive.

Mhedziso

Chinobvisa magetsi chinoshandiswa nemagetsi (RCBO) chinhu chakakosha mukuchengetedza magetsi emazuva ano. Nekubatanidza dziviriro yemagetsi anodarika mwero, mapfupi, uye kubuda kwemvura, RCBO inopa kuchengetedzeka kwakavimbika uye kwakaringana. Nezvinhu zvakaita sekukwanisa kupwanyika kwakanyanya, kuona magetsi anoramba aripo, uye nguva yekupindura nekukurumidza, maRCBO anovimbisa kugadzikana uye kuchengetedzeka kwemasisitimu emagetsi mudzimba, mabhizinesi, uye munzvimbo dzemaindasitiri zvakafanana. Kusarudza modhi chaiyo yeRCBO kunoita kuti masisitimu emagetsi ashande zvakanaka uye zvakachengeteka, zvichidzivirira vashandisi nemidziyo.
