Madiki ecircuit breakers: mhinduro dzakatetepa dzekuchengetedza

KunzwisisaMadiki eDunhu reMaputsi: Magamba Asingaimbirwi Ekuchengetedza Magetsi

Munyika yakaoma yemagetsi, kuchengetedzeka ndiko kwakakosha. Chimwe chezvinhu zvakakosha pakuona kuchengetedzeka uku i miniature circuit breaker (MCB). Kunyangwe ichiwanzo furatirwa, zvishandiso zvidiki izvi zvinoita basa rakakosha mukudzivirira macircuit kubva mukuremadzwa zvakanyanya uye kukuvara kwema short-circuit. Blog rino rinotsanangura kukosha, maficha uye mabhenefiti emaMCB, richitsanangura kuti nei akakosha munzvimbo dzekugara nedzekutengeserana.

Chii chinonzi miniature circuit breaker?

Chinopwanya dunhu diki, chinowanzo pfupikiswa seMCB, iswichi yemagetsi inongoerekana yagadzirwa kudzivirira macircuit kubva mukukuvadzwa ne overcurrent. Kusiyana nemafuse, ayo anoda kutsiviwa mushure mekushandiswa kamwe chete, maMCB anogona kudzorerwa patsva uye kushandiswazve, zvichiita kuti ave mhinduro iri nyore uye isingadhuri yekudzivirira macircuit.

MCB inoshanda sei?

Basa guru reMCB nderekukanganisa kuyerera kwemagetsi kana paine chikanganiso. Izvi zvinoitwa kuburikidza nenzira mbiri huru: kupisa uye magineti.

1. Kupisa: Iyi nzira inoshanda zvichibva papfungwa yekuburitsa kupisa. Kana paine kuwanda kwemagetsi, magetsi akawandisa anogona kukonzera kuti bimetallic strip iri mukati meminiature circuit breaker ipise uye ikotama. Kukombama uku kunogumbura switch, kuchipwanya circuit uye kumisa kufamba kwemagetsi.

2. Magnetic Mechanism: Iyi mechanism yakagadzirirwa kupindura ma short circuits. Kana short circuit ikaitika, current inowedzera nekukurumidza inoita kuti simba remagineti rive rakasimba zvekudhonza lever, iyo inobva yakanganisa switch yomisa circuit.

Rudzi rwemuchina wekutambisa dunhu diki

Kune mhando dzakasiyana dzeMCB, imwe neimwe yakagadzirirwa kubata mazinga akasiyana ekushandiswa kwazvino uye kwakanangana. Mhando dzakajairika dzinosanganisira:

1. Rudzi B: MaMCB aya anodonha kana magetsi asvika katatu kusvika kashanu pane magetsi akayerwa. Anowanzo shandiswa munzvimbo dzekugara uko mukana wekuti magetsi akwire wakaderera.

2. Rudzi C: MaMCB aya anodonha kana magetsi asvika ka5 kusvika ka10 pane magetsi akayerwa. Akakodzera kushandiswa mumabhizinesi nemaindasitiri anoshandisa michina ine magetsi ekukwira, akadai semota nematransformer.

3. Rudzi D: MaMCB aya anodonha kana magetsi asvika kagumi kusvika makumi maviri pane magetsi akarongwa. Anoshandiswa mumaindasitiri chaiwo uko kunotarisirwa kuti magetsi akakwira zvikuru.

Mabhenefiti ekushandisa MCB

1. Kuchengetedzwa Kwakawedzerwa: MCB inopa dziviriro yakavimbika yemagetsi, ichideredza njodzi yemoto wemagetsi nekukuvara kwemidziyo.

2. Zviri nyore: Kusiyana nemafuse, maminiature circuit breakers anogona kugadziriswa zviri nyore mushure mekugumburwa pasina kutsiva, zvichideredza nguva yekushanda.

3. Kunyatsojeka: MaMCB anopa dziviriro chaiyo nekugumburwa pamatanho chaiwo emagetsi, zvichiita kuti dunhu rakakanganisika chete rikanganiswe ukuwo mamwe masisitimu achiramba achishanda.

4. Kugara kwenguva refu: MaMCB akagadzirwa kuti agare kwenguva refu, zvichiita kuti ave mhinduro inogara kwenguva refu yekudzivirira dunhu.

Kushandiswa kweMCB

MCB ine mashandisirwo akasiyana-siyana anosanganisira:

1. Dzimba dzekugara: Dzinodzivirira dzimba kubva pakuzara kwemidziyo yakawanda uye mapfupi, zvichiita kuti vanhu vari mudzimba nemidziyo yemagetsi vagare vakachengeteka.

2. ZVINOSHANDISA: Zvinodzivirira masisitimu emagetsi mumahofisi, muzvitoro zvekutengesa nedzimwe nzvimbo dzekutengeserana kubva pakurasikirwa nenguva dzinodhura dzekushanda uye kukuvara kwemidziyo.

3. Zvemaindasitiri: Dziviriro yakasimba yemichina yemumaindasitiri, kuderedza njodzi yekukundikana kwemagetsi uye kuvandudza mashandiro emagetsi.

Muchidimbu

Kunyangwe ma "miniature circuit breakers" ari madiki, kukanganisa kwawo kuchengetedzeka kwemagetsi kwakakura. Ma "MCB" anoita basa rakakosha mukudzivirira masisitimu emagetsi munzvimbo dzekugara, dzekutengeserana uye dzemaindasitiri nekupa kuchengetedzwa kwakavimbika, kwakarurama kwe "overload" uye "short circuit". Sezvo tekinoroji ichiramba ichifambira mberi, kukosha kwemagamba aya asina kurumbidzwa ekuchengetedza magetsi kucharamba kuchikura, zvichiita kuti masisitimu edu emagetsi arambe akachengeteka uye achishanda zvakanaka kwemakore anotevera.
