iimveliso

I-SPAJ 140 C isetyenziselwa i-short-circuit ekhethiweyo kunye nokukhusela umhlaba we-radial feeders.

I-over-current and earth-fault relay SPAJ 140 C edityanisiweyo isetyenziselwa ukhuseleko olufutshane lwesekethe kunye nomhlaba-fault-fault feeders kwi-solid-earthed, resistance-earthed or impedance-earthed systems.

Olu nxibelelwano lokhuseleko oludibeneyo lubandakanya iyunithi yangoku kunye neyunithi yempazamo yomhlaba enezixhobo eziguquguqukayo zokuhamba kunye neempawu.

Olu dluliselo lunokusetyenziselwa ezinye izicelo, ezifuna ukhuseleko olulodwa, ezimbini, okanye ezithathu ngaphezulu kwangoku. Le idityanisiweyo over-current kunye ne-fault-fault relay nayo ibandakanya iyunithi yokukhusela i-circuit-breaker failure.

Ububanzi:Ukhuseleko oludityanisiweyo lwe-overcurrent kunye nomgangatho womhlaba

Izibonelelo zeMveliso:Eyona nto ixhaphakileyo isetyenziswa ngokukhuselwa kwamanani kwimarike.

Iimpawu zeMveliso:

I-1.Easy-to-use relay eneyona misebenzi ibalulekileyo yokhuseleko lwangoku kunye nokhuseleko lomhlaba

I-2.I-teknoloji eqinisekisiweyo: Isigaba sesithathu, i-low-set phase overcurrent unit kunye nexesha elichanekileyo okanye inverse definite minim (IDMT) uphawu.

I-3.Inqanaba lesithathu, i-high-set phase overcurrent unit kunye nokusebenza kwexesha elikhawulezayo okanye eliqinisekileyo Iyunithi ye-fault-fault unit kunye nexesha eliqinisekileyo okanye inverse echanekileyo yexesha eliqingqiweyo (IDMT) uphawu Iyunithi yecala eliphezulu lomhlaba kunye nokusebenza ngokukhawuleza okanye ixesha eliqinisekileyo.

I-4.I-built-in-built-in-circuit-breaker failure protection: Inkqubo yokuzimela ngokuqhubekayo ibeka iliso ekusebenzeni kwe-electronics kunye ne-microprocessor.
