Chifukwa chiyani chowotcha chochepa chamagetsi chimalephera kugwira ntchito

Why does the low-voltage circuit breaker fail to operate

Kulephera kwa magwiridwe antchito alow-voltage circuit breakerzimawonetsedwa ndi kukokera kapena kusagwira ntchito bwino kwawowononga dera.Chifukwa ntchito yofunika kwambiri komanso yofunika kwambiri yamagetsi othamanga kwambiri ndikuchita bwino ndikuchotsa mwachangu zolakwika za grid.Ngati ndiwowononga deraikakokedwa kapena kusunthidwa molakwika, izi zitha kukhala zowopsa ku gridi yamagetsi.Zifukwa zazikulu ndi izi: ①Kufutukula kukula kwa ngozi kungapangitse kuti vuto la dera limodzi lokha liwonjezeke ku basi yonse, kapenanso makina onse ndi makina onse adzakhala opanda mphamvu;②Ngati ikulitsidwa Nthawi yochotsa zolakwika idzakhudza kukhazikika kwa dongosolo ndikuwonjezera kuwonongeka kwa zida zoyendetsedwa;③kuyambitsa ntchito yosakwanira.Chotsatira chake, nthawi zambiri chimayambitsa ntchito yachilendo ya chitetezo cha gridi yamagetsi ndi oscillation, zomwe zimakhala zosavuta kuwonjezera pa ngozi ya dongosolo kapena kuzimitsa kwakukulu.

Zifukwa zazikulu za kulephereka kwa ntchito ndi:

  1. Kuwonongeka kwa makina ogwiritsira ntchito;
  2. Zowonongeka zamakina za thupi lophwanyira dera;
  3. Kulephera kugwira ntchito (kuwongolera) magetsi.
