Q:1.Puas yog cov kev tsis sib xws ntawm ib tus ncej thiab peb-theem ncej?
A: Yog. Nqus interrupter, ntsuas voltage, ntsuas tam sim no, luv luv-circuit breaking muaj peev xwm thiab dielectric withstand qib yog zoo tib yam. Qhov txawv yog nyob rau hauv kev khiav hauj lwm mechanism kev npaj thiab tswj lub tswv yim.
Q:2.Puas ZW(G)-40.5 ib tus ncej muaj rau 60Hz daim phiaj?
A: Nws yog sib xws rau ob qho tib si 50Hz thiab 60Hz tes hauj lwm. Thov qhia qhov zaus ntawm koj qhov kev txiav txim.
Q:3.Qhov twg tus nqi ntau dua, ib tus ncej lossis peb theem?
Yog lawm. Rau kev sib npaug sib npaug, 3 ib leeg-ncej units raug nqi ntau dua ib qho kev sib tw peb-theem breaker, ntxiv rau tus nqi ntxiv rau theem-segregated FTU.
Q: Dab tsi yog cov ntawv thov raug cai?
A: Phase-segregated ib tug ncej: 40kV ib-theem faib kab, railway traction mov, tes hauj lwm xav tau SPAR. ✅ Ganged peb-theem: Standard 35kV peb-theem feeders, transformer feeders, capacitor banks.
Q:5. Dab tsi tswj voltage xaiv muaj?
A: Txheem tswj voltages: AC220V, DC220V, DC110V. Phau ntawv them nqi thiab phau ntawv mus ncig yog tus qauv.
Q:6.Pob ib ncej ZW(G)-40.5 puas muab ntsia rau hauv switchgear?
Nws yog ib qho sab nraum zoov ncej-mounted VCB tsim rau cov kab nyiaj siv ua haujlwm. Nws yogtsis pom zoo rau sab hauv tsev switchgear cubicle. ZN85-40.5 yog qhov nyiam sab hauv tsev 40.5kV tov.
