Nzira yekusarudza iyo yakakodzera yedunhu breaker?

Kusarudza yakakodzeracircuit breakerinoda kuongororwa kwakadzama kwemaparamita edunhu, hunhu hwemutoro, nzvimbo yekuisa, uye zvinodiwa zvekudzivirira. Izvo zvakakosha zvinotariswa ndezvekuti iyo yakayerwa voltage inoenderana neiyo system voltage, iyo yakayerwa ikozvino yakakura kupfuura inotakura ikozvino asi ishoma pane iyo conductor ikozvino-inotakura simba, uye iyo yekutyora simba (Icu) yakakwirira kupfuura inotarisirwa pfupi-circuit ikozvino.

Key Parameter Sarudzo

Rated Voltage: Inofanira kuva ≥ mutsara wemagetsi emagetsi (somuenzaniso, anowanzoshandiswa mudzimba 220V / 380V). Iyo undervoltage yekuburitsa voltage inofanirwa kuenderana neiyo system voltage.

Yakatemerwa Zvazvino:

Verenga iyo yakanyanya kushanda ikozvino yemutoro (Ib). Sarudza acircuit breakerine chiyero chemazuva ano (In) chinosangana nemamiriro anotevera: Ib

Derted oparesheni inodiwa munzvimbo dzepamusoro-tembiricha (> 40 ℃).

Kutyora Kugona (Icu):

Inofanira kuva yakakura kudarika mutsara unotarisirwa kupfupika-munguva yenguva pfupi (Ik), iyo inogona kuverengwa uchishandisa mafomula kana nekutaura kumatafura (semuenzaniso, yetransformer inokwana 1600kVA, Ik≈38.5kA). 3

Isa pakutangacircuit breakersine Icu ≥ 50kA; yekushandiswa kwekugara, ≥ 6kA yakakwana.
