Structural Characteristics
1. MCB inonyanya kuumbwa nemaitiro ekushanda, maitiro ane simba uye akadzikama, chikwata cherwendo, arc yekudzima mudziyo uye zvimwe zvikamu.Uye ese akaiswa mu insulating shell yakagadzirwa neakakwirira kuramba yakaoma, inokanganisa inodzivirira epurasitiki.
2. Paunenge uchisundira mubato wekushanda kune "ON" nzvimbo, iyo inoshandiswa inoshandiswa inovhara mafambisirwo ekufambisa uye static kuvhara dunhu.Kana kukanganisa kwakanyanya kunoitika pamutsara, iyo yakawandisa ikozvino inoita kuti thermal bimetal element ikotame uye vertebral inofambisa lever inogadzirisa zvakare mechanical locking mechanism, uye kushamwaridzana kunofamba kunokurumidza kusiya static contact, nokudaro kuwana kuchengetedzwa kwepamusoro kwemutsara;kana kukanganisa kupfupi kunoitika pamutsara, iyo pfupi yedunhu ikozvino inokonzera iyo instantaneous tripper , The push rod inosundira iyo lever kuti igadzirise iyo yekuvhara nzira kuti iwane kupfupika kwekudzivirira kwedunhu.
3. Iyo 2P, 3P uye 4P mabreaker edunhu akashongedzerwa ane linkage tripping mudziyo, uye mubato unoshanda wakabatana netsvimbo yekubatanidza, isingakonzere tsaona yechikamu chedunhu.
4. Poli imwe neimwe ine chimiro chekushanda chekuchinja chiratidzo
Normal Working Condition
1. Ambient air tembiricha: -5°C~+40°C, uye avhareji kukosha mukati maawa 24 haipfuuri +35°C.
2. Altitude: Kukwirira kwenzvimbo yekuisa hakupfuuri 2000m.
3. Mamiriro emumhepo: hunyoro hwemuchadenga husingapfuuri 50% pakupisa kwe +40 ° C;hunyoro hwepamusoro hwehukama hunobvumirwa pane tembiricha yakaderera, uye avhareji yepamusoro hunyoro hunyoro hwemwedzi wakanyorova ndeye 90%, uye mwedzi wemwedzi Ivhareji tembiricha haipfuure +20 ° C, uye kufunga kunofanira kupihwa kune condensation inoitika. pamusoro pechigadzirwa nekuda kwekushanduka kwekushisa.
4. Dhigirii rekusvibisa: Dhigirii rekusvibisa reMCB idanho rechipiri.
5. Kuisa chikamu (overvoltage category): Chikamu chekuisa cheMCB ndicho II.
6. Yakaiswa panzvimbo isina kukanganiswa kukuru uye kuzunguzika, pasina kuputika kwepakati nengozi, pasina mhepo inoputika kana huruva inoparadza simbi uye kuparadza insulation, hapana kunaya uye chando kurwisa.
7. Mamiriro ekuiswa: TH35 njanji yegwara rinoshandiswa pakuisa uye kuiswa mumagetsi ekugovera kabati uye bhokisi rekugovera.Paunenge uchiisa, inofanirwa kuiswa yakatwasuka, ine mubato unosvika kune simba-panzvimbo.
Shape uye Installation Dimensions
Kuiswa, Kushandisa Uye Kugadzirisa
1. Kuiswa
◇ Panguva yekuisa, tarisa kana iyo yakakosha tekinoroji data rezita rinosangana nezvinodiwa zvekushandisa.
◇ Tarisa MCB woishandisa kakawanda.Chiito chacho chichave chakasununguka uye chakavimbika.Kuiswa kunogona kuitwa chete mushure mekusimbisa kuti haina kusimba.
◇ Iyo MCB inofanirwa kuiswa zvinoenderana nezvinodiwa.Magumo anouya ndiwo divi rekupa magetsi pamusoro pekutyora, uye iyo inobuda inobuda idivi remutoro pazasi peMCB, nzvimbo yepamusoro yemubato ndiyo nzvimbo yakavharwa yekubata.
◇ Kana uchiisa, tanga waisa MCB paTH35 yakajairika njanji.Woisa waya dzinopinda nedzinobuda muterminal, uye shandisa screws kuwana MCB.Nharaunda-chikamu chetambo yakasarudzwa yekubatanidza inofanira kuenderana neyakarongwa ikozvino (ona Tafura 3).
| Rated ikozvino A | ≤6 | 10 | 15 | 20 | 25 | 32 | 40 | 50 | 63 |
| Sectional nzvimbo ye conductor mm2 | 1 | 1.5 | 2.5 | 2.5 | 4.0 | 6.0 | 10 | 10 | 16 |
2. Kushandisa uye kugadzirisa
◇ Hunhu hwekudzivirira hweMCB huchagadzikwa nemugadziri, uye hauzogadziriswe pamadiro panguva yekushandiswa kudzivirira kukanganisa kuita.
◇ Mushure mekunge MCB yave rwendo nekuda kwekuremerwa kana kuchengetedzwa kwedunhu pfupi, mhosva ichatanga yabviswa uyezve MCB ichavharwa.Pakuvhara, mubato unodhonzerwa pasi kuti ugadzirise mashandiro e "buckle", uye wosundirwa kumusoro kuti uvhare.
◇ Kana kudzivirira kwekuremerwa kweMCB kwaputswa uye kukanganisa kwabviswa, zvinofanirwa kunge zviri maminetsi gumi tisati tavhara.
◇ MCB ichaongororwa nguva nenguva panguva yekushanda.Simba remagetsi richagurwa panguva yekuongorora.
◇ Iyo MCB haizorwiswa nekudonhedzwa nemvura nechando panguva yekushandiswa, kuchengetedza kana kufambisa.
Kuodha Mirayiridzo
Mushandisi anofanira kutsanangura zvinotevera pakuhodha:
1. Zita uye muenzaniso
2. Yakatemerwa ikozvino
3. Rudzi rwepakarepo overcurrent release
4. Nhamba yematanda
5. Huwandu
Semuenzaniso: kurongeka CAB6-63 mini circuit breaker, rated current 32A, type D, 3P (3 pole), uwandu 100 PCS.
