Kev kuaj qis heev zaus (VLF kuaj) yog txoj kev ua tau zoo los ntsuas kev laus ntawm kev laus ntawm lub cev muaj zog rwb thaiv tsev. Nws simulates kev ntxhov siab hauv kev ua haujlwm rau lub cev muaj zog los ntawm kev thov ultra-tsawg zaus (feem ntau}. 1Hz lossis tsawg dua) AC voltage los kuaj seb puas yog kev laus ntawm cov rwb thaiv tsev system. Hauv qab no yog cov lus qhia ntxaws ntxaws txog yuav ua li cas Ultra-Tsawg zaus soj ntsuam ntsuas ntsuas lub cev muaj zog rwb thaiv tsev laus.
1. Kuaj hauv paus ntsiab lus
Lub Ultra-Tsawg zaus sim siv tsawg zaus AC qhov hluav taws xob ac voltage kom thov hluav taws xob teb rau simulate cov haujlwm.
Lub xeev ntawm cov rwb thaiv tsev cov txheej txheem tuaj yeem raug txiav txim los ntawm kev saib xyuas tam sim no, hluav taws xob maj, lossis tso tawm ib nrab teeb liab thaum ntsuas.
2. Ntsuam xyuas cov ntsuas
Kev hloov pauv tam sim no: Rwb thaiv tsev laus yuav ua rau muaj kev kub ntxhov tam sim no, thiab cov degree ntawm kev tswj hwm kev hloov pauv ntawm qhov kev hloov pauv tam sim no.
Kev tso tawm ib nrab: rwb thaiv tsev kev laus feem ntau nrog kev tawm tsam ib feem; Kev kuaj VLF tuaj yeem kuaj tau lub zog thiab ntau zaus ntawm kev tawm teeb liab.
Voltage WaveForm: Cove rwb thaiv tsev puas tuaj yeem ua rau hluav taws xob ntub dej tuaj yeem ua rau muaj kev tiv thaiv hluav taws xob, thiab lub xeev rwb thaiv tsev tuaj yeem txheeb xyuas los ntawm kev ntsuas cov kev hloov ua kom nruj.
3. Kuaj cov txheej txheem
Kev npaj: Disconnect lub cev muaj zog muab thiab ua kom muaj kev nyab xeeb hauv paus, xaiv cov kev ntsuam xyuas tsim nyog.
Thov kev voltage: maj mam nce ultra-tsawg zaus voltage rau tus nqi preset (feem ntau 1.5 txog rau lub sijhawm ntsuas (feem ntau) rau 30 feeb).
Kev Ntsuam Xyuas thiab Kev Ntsuam Xyuas: Sau cov tam sim no, voltage waveform lossis ib nrab paib teeb liab thaum ntsuas, thiab txheeb xyuas cov xwm txheej rwb thaiv tsev.
4. Txheeb xyuas cov ntawv xeem
Kev thaiv ib txwm yog rwb thaiv tsev: ruaj khov tam sim no, tsis muaj distortion ntawm voltage waveform, tsis muaj feem tua teeb liab.
Me ntsis kev laus: qhov tam sim no nce ntxiv, lub voltage waveform yog me ntsis distorted, thiab ib feem tawm ntawm lub teeb liab tsis muaj zog.
Kev laus loj: Tam sim no nce siab heev, lub voltage waveform yog tiag distorted, thiab ib nrab tawm teeb liab yog muaj zog.
Los ntawm VLF kuaj, kev laus ntawm lub cev muaj zog muaj peev xwm kev hloov kho thiab hloov lub cev muaj zog, yog li txuas ntxiv lub neej thiab txo txoj haujlwm kev pheej hmoo.
