APF lub zog lim dej

•Rau lub tshuab hluav taws xob thiab lub cev muaj zog, kev poob ntxiv yog tshwm sim los ntawm kev sib haum xeeb lossis kev sib haum xeeb hauv cov stator windings, rotor circuits thiab hlau cores, uas txo cov kev ua tau zoo ntawm lub zog tsim hluav taws xob, kev sib kis thiab cov khoom siv hluav taws xob.

•Harmonic voltage tuaj yeem ua rau sine waves sharper, uas tsis tsuas yog nce hysteresis thiab eddy tam sim no poob nyob rau hauv cov khoom siv hluav taws xob xws li motors, transformers, capacitors, thiab lwm yam, tab sis kuj ua rau cov hluav taws xob load ntawm insulating cov ntaub ntawv.

Txij li thaum lub loads ntawm motors, transformers, hwj chim capacitors, cables, thiab lwm yam hloov ntau zaus, nws yog yooj yim dua los tsim series los yog parallel resonant xeev nrog ib tug loj tus naj npawb ntawm harmonic qhov chaw muaj nyob rau hauv lub hwj chim daim phiaj, uas tsim harmonic oscillations, generating overvoltage los yog overcurrent, uas compromises kev nyab xeeb kev khiav hauj lwm ntawm motors, transformers, thiab lwm yam kev thauj mus los thiab hluav taws xob sib tsoo tshuab.

•Harmonics nyob rau hauv lub tshuab hluav taws xob tuaj yeem ua yuam kev hauv cov cuab yeej ntsuas uas tiv thaiv cov lus qhia thiab ntsuas kom raug. Thaum lub Circuit Court breaker cuam tshuam tam sim no nrog cov ntsiab lus siab sib haum xeeb, lub peev xwm tawg ntawm Circuit Court breaker tau txo qis heev, ua rau arcing, luv Circuit Court, thiab txawm tawg ntawm Circuit Court breaker.

-Qhov muaj kev sib haum xeeb tuaj yeem yooj yim ua rau muaj teeb meem lossis tsis ua haujlwm ntawm ntau yam kev tiv thaiv hluav taws xob thiab cov khoom siv tsis siv neeg, nrog rau kev cuam tshuam suab hauv kev sib txuas lus, uas, yog tias muaj teeb meem loj, tuaj yeem hem cov khoom siv sib txuas lus thiab kev nyab xeeb ntawm tus kheej.

Lub Active Power Filter (APF) txuas nrog lub mains nyob rau hauv parallel. Nws tuaj yeem ntes qhov voltage thiab tam sim no ntawm qhov nyiaj them poob haujlwm hauv lub sijhawm. Tom qab kev xam los ntawm chav tswj, lub dav hlau mem tes modulation teeb liab yog siv los tsav IGBT-module. APF txhaj ib qho tam sim no rau hauv lub network uas sib npaug hauv qhov loj tab sis rov qab rau theem mus rau qhov sib haum xeeb tam sim no hauv lub network. Ob qhov kev sib raug zoo tam sim no tso tseg ib leeg, yog li ua haujlwm ntawm kev sib haum xeeb lim dej, dynamically compensating reactive zog thiab muab qhov xav tau qhov tam sim no.
