Chigadzirwa Chinonyanya Kuzivikanwa - CNAISO MCB

1. MuchidimbuyeMCB 

Miniature circuit breaker, inodaidzwa seMCB (Micro Circuit Breaker/ Miniature Circuit Breaker), ndiyo inonyanya kushandiswa kuchengetedza mudziyo mukuvaka magetsi emagetsi ekugovera magetsi.Inoshandiswa kune imwe-chikamu uye matatu-chikamu chipfupi chedunhu, kuwandisa uye overvoltage kudzivirira pazasi 125A, kusanganisira single-pole 1P, maviri-pole 2P, matatu-pole 3P, uye ina-pole 4P.

Miniature circuit breakers inoumbwa nemaitiro ekushanda, mabatirwo, zvidziviriro zvekudzivirira (zvakasiyana-siyana zvinoburitswa), uye arc kudzimisa masisitimu.Mabatirwo ayo makuru anoshanda nemaoko kana kuvharwa nemagetsi.Mushure mekunge iyo huru yekubata yakavharwa, iyo yemahara yekufamba michina inovhara iyo huru yekusangana munzvimbo yakavharwa.Iyo coil yekusunungurwa kwepamusoro uye chinhu chinopisa chekusunungurwa kwekushisa chakabatanidzwa mumutsara nedunhu guru, uye coil ye undervoltage release inobatanidzwa mukuenderana nemagetsi.Kana iyo dunhu iri pfupi-yakatenderedzwa kana yakanyanyisa kuremerwa, iyo armature yekuburitswa kwepamusoro inodhonzwa mukati kuti iite yemahara rwendo mechanisheni kuita, uye iyo huru yekubata inobvisa iyo huru yedunhu.Kana iyo dunhu yaremerwa, iyo inopisa chikamu chekupisa chinopisa chinopisa uye kukotamisa bimetal, ichisundira iyo yemahara yekuburitsa nzira kuti iite.Kana iyo yedunhu iri undervoltage, iyo armature ye undervoltage kuburitswa inoburitswa.Uyewo shandisa nzira yekusununguka yekufamba

3.Chinangwa cheMCB ?

Mukugadzira zvivakwa zvevagari, yakaderera-voltage circuit breaker inonyanya kushandiswa pakuremedza mutsara, pfupi-circuit, over-current, voltage loss, under-voltage, grounding, leakage, automatic switching of dual power sources, nekudzivirira nekushanda kwemamotors panguva. kasingaperi kutanga.Misimboti Pamusoro pekutevedzera misimboti senge mashandisiro emamiriro ekunze emidziyo yemagetsi yakaderera (ona Industrial and Civil Power Distribution Design Manual), zvinotevera zvinofanirwa kutariswa:

1) Iyo yakatemerwa voltage yedunhu rinoputika haifanire kunge iri pasi peiyo rated voltage yemutsara;

2) Ikozvino yakarongedzerwa yedunhu rinoputika uye yakarongerwa ikozvino yekusunungurwa kwepamusoro haisi pasi peiyo yakaverengerwa ikozvino yemutsetse;

3) Iyo yakarongerwa pfupi-yedunhu kutyora kugona kwemutsimba wedunhu haisi pasi peiyo yakanyanya kupfupi-yedunhu ikozvino mumutsara;

4) Kusarudzwa kwemagetsi ekugovera maseketi mabreaker anofanirwa kufunga nezve kunonoka-nguva pfupi-yedunhu-ku-off kugona uye kurongeka pakati pekunonoka kuchengetedza mazinga;

5) Iyo yakatemerwa voltage ye undervoltage kuburitswa kwedunhu breaker yakaenzana neiyo rated voltage yemutsara;

6) Kana ichishandiswa pakudzivirira mota, kusarudzwa kwemutsigiri wedunhu kunofanirwa kufunga nezvekutanga ikozvino kwemota uye kuita kuti isashande mukati menguva yekutanga;ona "Industrial uye Civil Power Distribution Design Manual" yekugadzira masvomhu;

7) Kusarudzwa kwevashambadziri vedunhu kunofanirawo kufunga nezvekusarudza kusarudzwa kwevashambadziri vematunhu uye mavhiriki emagetsi, mavhiriki uye fuses.

4.1: Injiniya yakazara uye rutsigiro rwehunyanzvi: 3 nyanzvi vagadziri, uye tekinoroji sevhisi timu.

4.2: Hunhu ndiNo1, tsika dzedu.

4.3: Kurumidza kutungamirira nguva: "Nguva igoridhe" kwauri uye kwatiri

4.4: 30min nekukurumidza mhinduro: tine timu yehunyanzvi, 7 * 20H

Wana kuvimba kwevatengi nekuda kwemukurumbira wavo wakaratidza kuvimbika, kuita uye hupenyu hurefu.

Kana uine chero mubvunzoskana chero chigadzirwa chinoda, ndapota inzwa wakasununguka kundibata.
