Kuongororwa kweMabasa uye Mashandisirwo eMCB Circuit Breakers

Mumagetsi,kuchengetedzeka uye kushanda zvakanaka ndizvo zvakakosha. MaMinitary circuit breakers (MCBs) chimwe chezvinhu zvakakosha zvinovimbisa zvese zviri zviviri.MaMCB zvishandiso zvakakosha mukuisa magetsi mudzimba, mumabhizinesi, uye mumaindasitiri, zvichidzivirira maseketi kubva pakuzara uye mashort circuits. Chinyorwa chino chichaongorora mashandiro, mhando, mabhenefiti, uye nzira dzekuisa maMCB kuti zvikubatsire kunzwisisa zvakakwana chikamu ichi chakakosha chemagetsi.

Chii chinonzikamuchina kekupwanya dunhu kadiki (MCB)?

Miniature circuit breaker (MCB) iswitch inodzima otomatiki inobvisa circuit kana paine overload kana chikanganiso chaonekwa. Kusiyana nemafuse echinyakare anofanirwa kutsiviwa mushure mekuvhuvhuta, MCB inogona kudzoserwa patsva mushure mekugumburwa, zvichiita kuti ive mhinduro iri nyore uye yakavimbika yekudzivirira circuit. MCB dzakagadzirirwa kudzivirira circuit kubva mukukuvadzwa kunokonzerwa ne overcurrents, izvo zvinogona kukonzera kupisa kwakanyanya uye njodzi dzemoto.

Chii chinonzi musimboti wekushanda kweminiature circuit breaker (MCB)?

Maminiature circuit breakers (MCBs) anoshanda zvichibva pamatanho maviri: thermal mechanism uye magnetic mechanism. Thermal mechanism inopindura mamiriro ekuwedzerwa kwesimba, apo current inodarika simba redunhu. Overload current inopisa bimetallic strip, zvichiita kuti ikotame uye itange switch, nokudaro ichityora circuit.

Kune rumwe rutivi, magnetic mechanism yakagadzirirwa kubata ma short circuit. Kana short circuit ikaitika, current inokurumidza kukwira, ichigadzira simba remagineti rakasimba rinodhonza control lever, richida kudzima circuit ipapo ipapo. Iyi dual mechanism inoita kuti miniature circuit breaker ikwanise kuchengetedza circuit kubva mukuwanda kwemagetsi uye ma short circuit.

Mhando dzema "miniature circuit breakers"

Maminiature circuit breakers anouya mumhando dzakasiyana-siyana, imwe neimwe yakagadzirirwa kushandiswa kwayo:

1. Rudzi B Miniature Circuit Breaker: Rudzi urwu rwemuchina wekupwanya magetsi une simba rekupwanya magetsi rinopetwa katatu kusvika kashanu kupfuura simba rakatarwa uye rakakodzera kushandiswa mudzimba uko mutoro wacho unodzivirira zvakanyanya, zvakaita semwenje nekupisa.
2. Rudzi C Miniature Circuit Breaker: Rudzi urwu rwemuchina wekupwanya magetsi une simba rekupwanya magetsi rinopetwa ka5 kusvika ka10 kupfuura simba rakatarwa, zvichiita kuti rive rakakodzera kushandiswa mumabhizinesi nemaindasitiri nemidziyo inductive loads yakaita semota nematransformer.
3. Rudzi D Miniature Circuit Breaker: Rudzi urwu rwecircuit breaker rune current inogumira ka10 kusvika ku20 pane current yakayerwa uye yakakodzera kushandiswa kwezvinhu zvinorema zvine ma surge currents akakwira, akadai semamota makuru nemajenareta.
4. Madhiraivha madiki erudzi rweK nerudzi rweZ:Idzi imhando dzakagadzirirwa mashandisirwo chaiwo, akadai sekudzivirira mitoro yemagetsi kana michina yemagetsi inonzwisisika.

Zvakanakira kushandisa ma "miniature circuit breakers"

Zvichienzaniswa nemafusi echinyakare, ma miniature circuit breakers (MCBs) ane zvakanakira zvinotevera:

• Inogona kugadziriswazve:Kusiyana nemafuse, maMCB anogona kugadziriswazve mushure mekugumburwa, zvichibvisa kudiwa kwekutsiviwa uye kuderedza nguva yekushanda.
• Kukurumidza Kupindura: Kana paine chikanganiso, MCB ichakurumidza kugumburwa kuderedza njodzi yekukuvadzwa kwemidziyo yemagetsi uye kuderedza njodzi dzemoto.
• Dhizaini Yakamanikana: MaMCB madiki uye madiki pane mafuse, zvichiita kuti nzvimbo ye switchboard ishandiswe zvakanaka.
• Kuchengetedzwa Kwakawedzerwa: MCB inopa kuchengetedzeka kwakanyanya nekudzivirira moto wemagetsi nekukuvara kwemidziyo kunokonzerwa nekuwanda kwemagetsi uye mashort circuits.

Ndeupi musiyano uripo pakati peMCB neRCD?

RCD inotarisa kusarongeka kwemagetsi, kunyanya kubuda kwemvura panyika. Inoita kuti mvura iende pasi isingatarisirwi ionekwe uye imire nekukurumidza, ichidzivirira kuvhunduka kwemagetsi. MCB inotarisa kuti mvura inopinda mumhepo yakawandisa sei mudunhu.

Kuiswa nekugadzirisa ma "miniature circuit breakers"

Pakuisa ma miniature circuit breakers (MCBs), mutoro wemagetsi uye mhando yeMCB yakakodzera yekushandisa zvinofanirwa kutariswa nekungwarira. Nguva dzose bvunza nyanzvi yemagetsi ine hunyanzvi kuti uve nechokwadi chekuiswa kwakakodzera uye kutevedzera mitemo yemagetsi yemuno.

Kugara uchigadzirisa ma "miniature circuit breakers" kwakakosha. Kuongororwa nguva dzose nekuongorora kunobatsira kuona matambudziko angangoitika asati akonzera kutadza kushanda zvakanaka. Kuve nechokwadi chekuti ma "miniature circuit breakers" anoshanda zvakanaka kunogona kuvandudza kuchengetedzeka nekuvimbika kwemasisitimu emagetsi.

muchidimbu

MaMinitary circuit breakers (MCBs) zvinhu zvakakosha mumagetsi emazuva ano, zvichipa dziviriro yakakosha uye kuchengetedzwa kwepfupi. MaMCB anowanikwa mumhando dzakasiyana-siyana kuti asangane nezvinodiwa zvakasiyana-siyana zvekushandisa. Kana tichienzanisa nemafuse echinyakare, maMCB ane mabhenefiti akawanda, anosanganisira mashandiro ekugadzirisa, nguva yekupindura nekukurumidza, uye kuchengetedzeka kwakawedzerwa. Kunzwisisa mashandiro uye kukosha kwemaMCB kwakakosha kune chero munhu anobatanidzwa mukuisa kana kugadzirisa magetsi, sezvo zvichibatsira kuona kuti magetsi akachengeteka uye anoshanda zvakanaka.
