Paub meej
SPAJ 140 C yog siv rau kev xaiv luv luv-circuit thiab lub ntiaj teb-kev tiv thaiv ntawm radial feeders.
Kev sib koom ua ke dhau-tam sim no thiab lub ntiaj teb-kev txhaum relay SPAJ 140 C yog siv rau kev xaiv luv luv-circuit thiab lub ntiaj teb-kev tiv thaiv ntawm radial feeders hauv solidly-earthed, resistance-earthed los yog impedance-earthed fais fab system.
Qhov kev tiv thaiv kev sib koom ua ke no suav nrog chav nyob dhau tam sim no thiab lub ntiaj teb kev ua txhaum nrog kev hloov pauv hloov pauv thiab cov chaw teeb tsa.
Cov relays no kuj siv tau rau lwm yam kev siv, uas yuav tsum tau ib zaug, ob, los yog peb-theem tiv thaiv dhau tam sim no. Qhov kev sib koom ua ke dhau-tam sim no thiab lub ntiaj teb-kev ua txhaum relay kuj muaj xws li kev tiv thaiv kev tiv thaiv hluav taws xob tsis ua haujlwm.
Scope: Ua ke overcurrent thiab tiv thaiv lub ntiaj teb txhaum
Cov txiaj ntsig khoom: Feem ntau siv cov lej tiv thaiv relay ntawm kev ua lag luam.
Khoom nta:
1.Easy-rau-siv relay nrog lub luag haujlwm tseem ceeb tshaj plaws rau kev tiv thaiv tam sim no thiab lub ntiaj teb txhaum
2.Proven thev naus laus zis: Peb-theem, qis-theem theem overcurrent chav tsev nrog lub sijhawm meej lossis hloov pauv lub sijhawm yam tsawg kawg nkaus (IDMT) tus yam ntxwv.
3.Three-theem, high-set theem overcurrent unit nrog instantaneous los yog meej lub sij hawm ua hauj lwm Low-set earth-fault unit nrog meej lub sij hawm los yog inverse definite yam tsawg kawg nkaus lub sij hawm (IDMT) yam ntxwv High-set earth-fault unit nrog instantaneous los yog meej lub sij hawm ua hauj lwm.
4.Built-in Circuit Court-breaker tsis ua haujlwm tiv thaiv: Kev saib xyuas tus kheej tsis tu ncua saib xyuas kev ua haujlwm ntawm cov khoom siv hluav taws xob thiab microprocessor.
