Intshayelelo yeMveliso

I-RDB8A-63 i-circuit breaker encinci (emva koku kuthiwa yi-circuit breaker), esetyenziswa kakhulu kwimigca yokusabalalisa yokukhusela kunye ne-AC 50Hz, i-voltage esebenzayo elinganisiweyo engagqithisi i-400V, i-current rated ingadluli kwi-63A, kunye ne-short-circuit breaking capacity engadluli kwi-6000A; inokusetyenziswa kwakhona kumbane we-DC unipolar ongagqithiyo kwi-110V, iipali ezimbini ezingagqithiyo kwi-220V, i-DC ereyithiweyo yangoku engagqithiyo kwi-63A, ireyithwe kwi-DC ye-short-circuit breaking capacity engagqithiyo kwi-6000A kwimigca yosasazo olukhuselayo; isetyenziselwa ukudibanisa okungaqhelekanga, ukuphulwa kunye nokutshintshwa kwemigca, ngokugqithiswa , Umsebenzi wokukhusela isiphaluka esifutshane. Ngexesha elifanayo, ineemodyuli ezinamandla ezincedisayo, ezifana nabafowunelwa abancedisayo, abafowunelwa kunye ne-alarm indication, ukukhululwa kwe-shunt, ukukhutshwa kwe-undervoltage, ulawulo lokude kunye nezinye iimodyuli.

Iimbonakalo

1.Inkqubo yokusebenza eqinisekisiweyo

2.Ivolumu encinci, umthamo omkhulu

3.Umthamo we-wiring onamandla kakhulu

4.I-insulation enhle phakathi kwezigaba

5.I-Super-strong conductivity

I-6.Ukunyuka kweqondo eliphantsi kunye nokusetyenziswa kwamandla

Uluhlu lwe-RDB8A i-circuit breaker yimveliso ye-circuit breaker enegunya eliphezulu lokunciphisa langoku kunye nokuthembeka okuphezulu okuphuhliswe ngokukodwa yi-People Electric kwishishini lonxibelelwano. Isetyenziswa kakhulu kwiinkqubo zokuhambisa amandla njengeekhabhinethi eziphambili, iikhabhinethi zamandla, iikhabhinethi zokuhambisa amandla, kunye neekhabhinethi zangaphandle kwishishini lonxibelelwano.Imveliso ihambelana ne: GB / T 10963.2 standard.

Iinkcukacha eziphambili zobugcisa

Iimpawu zokukhubeka ngokugqithisileyo: Phantsi kweemeko eziqhelekileyo zofakelo kunye nereferensi yobushushu be-ambient (30-35)°C

iimpawu zokukhubeka ngokugqithisileyo zomqhekezi wesiphaluka ziyahlangabezana neemfuno kwiThebhile yoku-1.

Umlinganiselo wokuqhawula i-short-circuit breaker of the circuit breaker iboniswe kwiThebhile 2.
