Miniature Circuit Breakers: Kuchengeta Yako Yekuchengetedza Sercuits Yakachengeteka

Overview

MCB mini- circuit breakerndeye yakawanda-inoshanda AC yakaderera-voltagecircuit breaker, ine kuwandisa, kupfupika kwedunhu, undervoltage uye kwakasimba kutyora kugona.

1. Mamiriro ezvinhu

• Iyo inoumbwa neyekutapurirana michina uye yekubata system;
• Nzira dzekufambisa dzakakamurwa kuita otomatiki uye manyorero;
• Kune marudzi maviri ematanho ekusangana masisitimu, imwe ndiyo yechinyakare kuonana, imwe yacho inogadziriswa chitubu chekushanda meshini yekubata.

2. Kuita kwehunyanzvi

• Iyo ine hunhu hwekuremedza, pfupi dunhu, undervoltage uye yakasimba yekutyora kugona;
• Iine maitiro ekubatana kwakavimbika uye kwenguva yakareba yakazaruka dunhu.

3. Mamiriro ekushandisa

• Kuisa nzira: kugadziriswa kwekugadzirisa, kuiswa kweflange;
• Insulation nzira: matanda matatu;
• Inokodzera AC 50Hz, rated insulation voltage is 630V ~ 690V, rated current is 60A ~ 1000A.

Chikamu cheApplication

MCBmini- circuit breakersanonyanya kushanda kune yekupinza uye kubuda kweakasiyana siyana ekugovera network, kunyanya kusanganisira:

• Lighting distribution circuit.
• Inoshanda kune simba rekugovera sisitimu sekudzivirirwa kwekuremerwa uye pfupi pfupi yemitsara;
• Inoshanda kune ese marudzi emota kutanga uye braking dziviriro.
• Inoshanda kune kutonga kwemagetsi ekushandisa masisitimu, akadai semwenje, terevhizheni, nhare uye komputa;
• Inoshanda kune nzvimbo dzisingawanzo kuchinjwa kana kushandiswa muzvikamu.
• Inonyanya kushandiswa pakudzivirira mutsara (kupfuura-ikozvino kuchengetedzwa), uye inopa basa rekudzivirira rekukurumidza kubvisa kukanganisa ikozvino kwechikanganiso chepfupi-chepamusoro munharaunda;
• Inogona kushandiswa semota yekutanga uye braking zvishandiso;
• Inogona kushandiswa pakuremedza uye kupfupika kwedziviriro yedunhu remagetsi ekushandisa;
• Inogona kushandiswa kuchengetedza mota uye transformer kubva kune yakawandisa uye undervoltage.

Mamiriro Ekushandisa

• 1, The ambient air tembiricha haifaniri kudarika + 40 ℃, uye haizove yakaderera pane - 5 ℃, hunyoro hwehukama hahupfuuri 90%, uye hunyoro hwehukama hwepamusoro hunobvumirwa pane tembiricha yakaderera;
• 2, Tembiricha yakaenzana yemhepo yakatenderedza haifanire kunge yakakwira kupfuura + 40 ℃;
• 4, Kukwirira kwenzvimbo yekuisa hakufaniri kudarika 2000m;
• 5, Mukati mepakati pasina njodzi yekuputika, uye mukati mepakati hamuna gasi kana chiutsi chinokwana kuita ngura simbi uye kuparadza insulation;
• 6, Hapana kudengenyeka kwechisimba, kukanganisa kana kuchinja kazhinji.
• 9, Mutsigiri wedunhu uye chigadziro chepasi chinogona kuiswa uye chakabatana maererano nemirairo yemugadziri kana chirevo chechigadzirwa;
• 10, Iyo inotyora yedunhu inogona kushandiswa pamwe chete nedanda rimwe chete uye akawanda-pole leakage dziviriro akaisirwa pairi kuti agadzire mudziyo wekudzivirira kuvuza.

Wiring Installation uye Precautions

1. Nzvimbo yekuisa:

Tembiricha yemhepo yakadzika ichave kubva -5 ℃ kusvika + 40 ℃, kazhinji haifanire kudarika + 35 ℃;24-awa avhareji tembiricha haifanire kudarika + 35 ℃, uye hunyoro hwepakati hwemhepo haifaniri kudarika 50%.

2. Nzvimbo yekuisa:

Kana iyo inoputika yedunhu yakaiswa padivi rekupinda kwemagetsi, iyo switch yekupedzisira yedunhu inoputika ichave yakavimbika pasi, uye kudzivirira kwekudzivirira pakati pedunhu rinoputika uye pasi pesimbi simbi ichave yakakura kupfuura 1000MΩ;

Kana iyo yedunhu inopwanya yakaiswa parutivi rwemagetsi inlet, haigone kudzika;

3. Mamiriro ekushandisa:

A circuit breaker ichaiswa panzvimbo yakatwasuka kana yakatwasuka.Kana ichi chinodiwa chikatadza kuzadzikiswa nekuda kwekuganhurwa kwenzvimbo yekukwira, matanho anotevera anogona kutorwa:

(1) Mazano ekubatsira anogadzikwa munzvimbo dzakakodzera pane terminal board yeaimbova mugovanisi wedunhu breaker.

Kuiswa kwakawanda 3 ~ 4. Kana muparadzi wedunhu asingakwanisi kushanda zvakajairika, inogona kudzika pasi nekuvimbika kuburikidza nekubatsirana.
