Ngokubanzi

YCM7YV series electronic case plastic circuit breaker (emva koku ekubhekiselwa kuyo njenge: i-circuit breaker) ilungele iigridi zamandla eziphantsi-voltage ezine-AC 50Hz, i-rerated insulation voltage 800V, i-voltage yokusebenza ereyithiweyo 400V nangaphantsi, kwaye ireyithwe ukusebenza ngoku ukuya kuthi ga kwi-800A. I-breaker circuit inomthwalo ogqithisiweyo wokulibaziseka kwexesha elide eliphambeneyo, i-short-circuit short-liuse inverse time limit, i-short-circuit-short-deach-deal-deep limit limit, i-short-circuit ngokukhawuleza kunye nemisebenzi yokukhusela i-voltage. Kwiimeko eziqhelekileyo, isiphaluka

I-breaker isetyenziselwa ukutshintshela okungaqhelekanga kweesekethe kunye nokuqaliswa okungaqhelekanga

Olu chungechunge lwee-breakers zesekethe lunomsebenzi wokuzihlukanisa, kunye nesimboli esihambelanayo "   "

Umgangatho: IEC60947-2.

Iimeko zokusebenza

1. Ubushushu bomoya obukuyo

a)Ixabiso eliphezulu lomda aligqithi ku +40℃;

b)Ixabiso lomda osezantsi alidluli -5℃;

c)Ixabiso eliphakathi kwiiyure ezingama-24 alidluli +35℃;

2. Ukuphakama

Ukuphakama kwendawo yofakelo akudluli kwi-2000m.

3. Iimeko ze-atmospheric

Ukufuma okunxulumene ne-atmosfera akubi ngaphezu kwe-50% xa i-ambient

ubushushu obuphezulu ngu +40°C; inokuba nokufuma okuphezulu okunxulumeneyo kwindawo esezantsi

amaqondo obushushu; xa umyinge wenyanga ubuncinci bobushushu obumanzi

inyanga yi +25°C, ubushushu benyanga obuphezulu benyanga ngu +25°C. Ukufuma okunxulumeneyo yi-90%, kuthathelwa ingqalelo ukuxinwa okwenzeka kwi-condensation

umgangatho wemveliso ngenxa yotshintsho lobushushu.

4. Isidanga songcoliseko

Idigri yongcoliseko yesi-3, izixhobo ezifakwe kwi-breaker yesekethe zineqondo le-2 longcoliseko.

5. Udidi lofakelo

Isekethe ephambili ye-circuit breaker iya kuba yinqanaba lofakelo lwe-III, kwaye isiphaluka esincedisayo kunye neesekethe zokulawula ziya kuba ludidi lofakelo lwe-II.

6. Iimeko zofakelo.

Izaphuli-mthetho zesekethe kufuneka zifakwe ngokuthe nkqo, ziqhele ukuba nocingo oluya phezulu, kunye nomhlaba wangaphandle wemagnethi kwindawo yofakelo akufuneki ugqithe ka-5 kumhlaba we-geomagnetic kulo naliphi na icala.
