1. Chii chinonziMCCB ?

 

Molded case circuit breakers inogona kutema otomatiki ikozvino mushure mekunge yazvino yadarika rwendo rwekurongeka.Plastic kesi inoreva kushandiswa kwepurasitiki insulators seyekunze casing yechishandiso kuparadzanisa ma conductor uye zvikamu zvesimbi zvakadzika.Molded kesi circuit breaker kazhinji ine thermal-magnetic trip unit, ukuwo mamodheru akakura akashongedzerwa ane solid-state trip sensors.Chikamu cherwendo chakakamurwa kuita: thermal magnetic trip uye electronic trip.Inowanzo shandiswa rated currents ndeaya anotevera: 16, 25, 30, 40, 50, 63, 80, 100, 125, 160, 200, 225, 250, 315, 350, 400, 500, 630A.

2. Feature ofMCCB ?

 

2.1:Teerera neGB14048.2008 zviyero;

2.2:Rated insulation voltage: 800V;

2.3:Saizi yeframe yakayerwa ikozvino: 63A;100A;225A;400A;630A;800A;

2.4:High kutyora simba: kusvika 100kA;

2.5:Dhizaini inonzwisisika, yakachengeteka uye yakavimbika, saizi yesamll, uremu huremu, kutaridzika kwakanaka;

2.6:Zvishandiso zvese, kukurumidza kuisirwa, nyore kushandisa, kwakasimba kushanda.

 

3.HowMCCBanoshanda?

Iwo makuru ekubatika eiyo low-voltage circuit breaker yakavharwa nemaoko kana 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 yakanyanya kuremerwa, iyo armature yekuburitsa yakawandisa inodhonzwa mukati kuti iite yemahara yekuburitsa michina iite, uye iyo huru yekubata inobvisa dunhu guru.

Kana iyo dunhu yaremerwa, iyo yekudziya yekudziya yekuburitsa inokotama bimetal, kusundira iyo yemahara yekuburitsa michina kuti iite, uye iyo huru yekubata inobvisa iyo huru yedunhu.

Kana dunhu riri pasi pe-voltage, iyo armature ye under-voltage kuburitswa inoburitswa, iyo inoitawo kuti yemahara rwendo mechanisheni iite, uye iyo huru yekubata inobvisa dunhu guru.

Kana bhatani rekufamba rikadzvanywa, iyo armature ye shunt tripper inodhonzera mukati, ichiita yemahara rwendo mashandiro kuita, uye iyo huru yekubata inobvisa dunhu guru.

 

 

4.Sei Yueqing AIso?

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.
