Nruab nrog lub siab - precement metering nti, cov khoom ua tiav tau cov ntsiab lus ntawm chav kawm 0.5s. Nws tuaj yeem sau peb {- theem voltage, tam sim no, siv hluav taws xob / reactive, thiab tag nrho cov ntaub ntawv hluav taws xob tsis muaj tseeb. Nws tuaj yeem khaws 12 lub hlis ntawm keeb kwm hluav taws xob cov ntaub ntawv hauv zos. Txhawb nqa cov qauv kev sib txuas lus ntawm Rs485 thiab NB- iTage tsis siv neeg thiab kev siv cov meter 'meter' kev nyeem ntawv zoo los ntawm ntau dua 70%.
Nws tau txhim tsa - hauv anti- Kev tiv thaiv cov teeb meem xws li kev tiv thaiv hluav taws xob, thiab muaj kev tiv thaiv tiag tiag {lub sij hawm kev nyab xeeb. Ib qho ntxiv, nws tuaj yeem txuas nrog cov chaw tswj hwm hluav taws xob ntse los tsim hluav taws xob siv hluav taws xob thiab kev ua tiav ob peb lub ntsuas thiab kev tswj hwm thiab tswj.
3 Theem Ntse Ntse Hluav Taws Xob Hluav Taws Xob Cov Khoom Taw Qhia
Tus 3 {-}} theem ntse hluav taws xob hluav taws xob yog qhov tseem ceeb siv hluav taws xob kev lag luam muaj kev lag luam thiab kev lag luam. Nws tau sib haum nrog cov tshuab hluav taws xob ntawm 380V thiab saum toj no, thiab tuaj yeem ntsib hluav taws xob ntsuas xav tau ntawm cov xwm txheej, cov khw muag khoom, thiab chaw ua haujlwm.
