IiMeko zokuSebenza eziQhelekileyo kunye neeMeko zoFakelo lweZiqhelo zeSekethe ezibunjiweyo

Iimeko zoFakelo lwe-Case Molded Circuit Breaker:

1. Ubushushu bomoya we-Ambient - 5 +40;

2. Umphakamo wendawo yofakelo awuyi kudlula i-2000 m.

3. Umswakama ohambelana nomoya awudluli i-50% kwiqondo lokushisa eliphezulu kakhulu + 40 C. Umswakama ophezulu ophezulu unokuvunyelwa kumaqondo okushisa aphantsi, afana ne-90% kwi-20 C. Kufuneka kuthathwe amanyathelo akhethekileyo ukwenzela ukuxinwa ngezikhathi ezithile ngenxa utshintsho lobushushu.

4. Ibakala longcoliseko sisi-3.

5. Udidi lofakelo lwesekethe ephambili ye-circuit breaker yi-IV, kunye nodidi lofakelo lwesinye isiphaluka esincedisayo kunye nolawulo lwesekethe yi-III.

6. Izaphuli zesekethe zifanelekile kwindawo ye-electromagnetic A.

7. I-TH uhlobo lwe-circuit breaker inokumelana nempembelelo yomoya omanzi, i-salt spray, i-oil spray kunye ne-mold ngokusebenzisa i-GB / T 2423.4 kunye ne-GB / T 2423.18 iimfuno zovavanyo.

8. Ukuthambekela okuthe nkqo kofakelo lwe-circuit breaker akudluli kwii-degrees ezi-5.

9. Iziqhekeza zeesekethe kufuneka zifakwe kwiindawo apho kungekho ngozi yokudubula, kungekho luthuli oluqhubayo, akukho ukubola okwaneleyo kweentsimbi kunye nomonakalo wokugquma.

10. I-Circuit breaker ifakwe kwigumbi lekhabhinethi, kwaye isakhelo somnyango sifakwe.Inqanaba lokukhusela lifikelela kwi-1 P40.

IiMeko zokuSebenza zeZaphuli zeSekethe ezibunjiweyo:

1. Abaphuli beesekethe baphumelela iimfuno zovavanyo lwe-GB/T 2423.1 kunye ne-GB/T 2423.2.Ubushushu bomoya we-ambient bunokuba buphantsi njenge -25 (-40 (-40 (-40 (-40 (-40%)) kunye nomlawuli okrelekrele we-EN) kwaye buphakame njenge + 70 (-40 (-40 (-40) (-) I-40 (-40 (-40%) yokunciphisa umthamo).

2. Ukunciphisa umthamo ngaphezu kwe-2000 m ngaphezu komphakamo wolwandle;

3. Iimeko zogcino: iqondo lobushushu bomoya obukuyo ngu – 40 ~70 ~
