- Khoom Taw qhia
AC-6b capacitor lub luag hauj lwm contactor (los yog Capacitor switching Contactor) yog ib hom tshwj xeeb ntawm contactor tsim tshwj xeeb rau kev hloov fais fab capacitors hauv reactive fais fab nyiaj them (RPC) systems. Tsis zoo li tus qauv AC contactors, nws yog tsim los tswj lub siab inrush tam sim no uas tshwm sim thaum capacitors energized.
Nws lub luag haujlwm tseem ceeb yog: Hloov cov tsev txhab nyiaj capacitor hauv Automatic Power Factor Correction (APFC) panels, txwv tsis pub muaj kev cuam tshuam tam sim no thaum lub zog capacitor,
tiv thaiv kev sib cuag vuam & arcing tshwm sim los ntawm kev hloov pauv siab.

Nws ua haujlwm li cas?
● Ua ntej -theem nqi
Thaum lub contactor yog energized, tam sim no ntws los ntawm lubua ntej -them resistor(limiting inrush).
Capacitor nqi maj mam.
● Main Contact Kaw
Tom qab ncua sijhawm luv luv (~ 20-100ms), lubcov neeg tseem ceeb raug kaw, bypassing lub resistor.
Tag nrho cov tam sim no ntws los ntawm lub capacitor.
● De- zog
Thaum muab tua, lub capacitor tawm musntshav resistors.
Xaiv Phau Ntawv Qhia
● Capacitor Bank Rating (kVar)
Yuav tsum phim tus contactor's switching peev (piv txwv li, 25kVar, 50kVar).
● Qhov System Voltage (V)
Feem ntau:230V, 400V, 480V, 525V.690V
● Inrush tam sim no tuav
Yuav tsum tiv taus 50–100 × ntsuas tam sim no rau milliseconds.
● Ncej Configuration
3P (3-ncej) – Delta-connected capacitors.
4P (4-ncej) - Lub hnub qub txuas nrog nruab nrab.
● Tswj voltage
Chev voltage: 24V DC, 110V AC, 230V AC, thiab lwm yam.
● Hloov zaus
Rau kev hloov pauv ntau zaus (piv txwv li, APFC), xaiv cov qauv siv lub neej siab (100, 000+ cycles)
