FAQ

1) Cov cuab yeej siv no siv tau dab tsi los daws cov teeb meem kev ntsuas hauv thaj chaw muaj zog hluav taws xob cuam tshuam, thiab hom zaus nws txhawb dab tsi?

Teb:
Cov cuab yeej siv digital notch filtering thev naus laus zis los txo kev cuam tshuam los ntawm lub zog hluav taws xob zaus hluav taws xob, ua kom ntseeg tau qhov ntsuas qhov tseeb hauv qhov chaw muaj zog hluav taws xob. Nws txhawb ob hom zaus: ib zaug - zaus thiab tsis siv neeg dual - zaus hloov dua siab tshiab:
Ib zaug- zaus: 50.0Hz, 60.0Hz;
Nws pib dual zaus: 45.0Hz / 55.0Hz, 47.5Hz / 52.5Hz, 55.0Hz / 65.0Hz, 57.5Hz / 62.5Hz.

2) Dab tsi hauv av thiab xaim yuav tsum tau saib xyuas thaum siv lub tshuab hluav taws xob nrog lub tshuab hluav taws xob?

Teb:
Thaum siv lub tshuab hluav taws xob lossis lub zog siv hluav taws xob, ua raws li cov cai hauv qab no kom tsis txhob muaj "kev ua yuam kev hauv av" ceeb toom thiab ntsuas kev puas tsuaj:
Grounding Requirements: Lub grounding terminals ntawm ob lub cuab yeej thiab lub tshuab hluav taws xob / lub zog hluav taws xob yuav tsum tau txuas nrog lub ntiaj teb kom ntseeg tau tias muaj av zoo.
Cable Specifications:
Thaum kos lub zog los ntawm qhov chaw sau npe AC220V, hauv av N davhlau ya nyob twg (nruab nrab xaim) ntawm cov khoom siv hluav taws xob.
Thaum kos lub hwj chim los ntawm AC380V-cov ntawv sau npe, hauv av cov kab nruab nrab (N davhlau ya nyob twg) thiab txuas tsuas yog ib theem kab (L davhlau ya nyob twg) mus rau N davhlau ya nyob twg kom tau txais AC220V voltage. Kev txuas ob theem kab yog txwv nruj heev (kom tsis txhob siab -voltage 380V input).

3) Dab tsi tshwj xeeb kev xeem ua haujlwm thiab kev ceev faj zoo muaj nyob rau thaum ntsuas CVTs?

Teb:
Cov cuab yeej muab ob qhov kev sim tshwj xeeb rau CVTs (capacitive voltage transformers), nrog rau kev ceev faj hauv qab no:
Tshwj xeeb muaj nuj nqi:
Kev ntsuas yam tsis muaj kev cuam tshuam siab -voltage leads: Ntsuas qhov ntsuas dielectric poob thiab qhov muaj peev xwm yam tsis tau tshem tawm CVT qhov siab -voltage leads;
Rov qab-kev sib txuas tiv thaiv txoj kev ntsuas: Txoj kev no tso cai rau kev ntsuas ntawm dielectric poob thiab capacitance qhov tseem ceeb ntawm lub davhlau ya nyob twg sab sauv C0 ntawm CVT.
Cov kev ceev faj:
Thaum ua cov kev xeem CVT cais ( ntsuas C1 lossis C2 ib tus zuj zus), qhov thaiv sab nrauv ntawm HV liab siab -voltage lead yuav tsum sab laug ntab thiab tsis muab tso rau hauv av. Qhov no tiv thaiv kev ntsuas qhov tsis raug tshwm sim los ntawm kev faib tawm tsis kam-capacitance tsis sib xws ntawm HV txhuas thiab hauv av.
Qhov ntsuas hluav taws xob yuav tsum tsawg dua lossis sib npaug li 2kV (muaj feem xyuam rau ob qho tib si tus kheej -excitation thiab thim rov qab- txoj kev sib txuas tiv thaiv).
Thaum txuas mus rau tus kheej -cov zis zoo siab (ES davhlau ya nyob twg), siv lub ntsuas hluav taws xob txuas txuas txuas kom ntseeg tau tias muaj kev sib cuag zoo nrog CVT thib ob winding. Cov zis no yuav cia li deactivate thaum xaiv txoj kev ntsuas qhov zoo/tsis zoo.
