Multifunctional Fais Meter
Multiifunctional hluav taws xob hluav taws xob hluav taws xob hluav taws xob yog lub siab -}}} performanceမ်းက performance performance measur Ntsuas Cov Ntaus Ntawv Tsim rau Kev lag luam, lag luam thiab ntse tsev scenarios. Nws sib xyaw ua ke / tiv thaiv kev ntsuas hluav taws xob raug, ntsuas hluav taws xob / kev saib xyuas tam sim no, thiab cov zog precisatics txog rau chav kawm 0.5s rau cov ntaub ntawv txhim khu kev qha.
Nws txhawb ntau txoj kev sib txuas lus zoo li RS485 thiab NB- i6 lub sij hawm sib kis, thiab chaw taws teeb chaw. Nruab nrog overload, overvoltage, thiab toast lub tswb, nws ua kom muaj zog ua haujlwm. Nws txoj kev cog lus DIN 35 txoj kev tsheb nqaj hlau {6} mounted tsim tso cai yooj yim rau kev tswj hwm lub zog, tswj hwm kev tswj hwm, thiab ntse tswj kev sib koom ua ke.

Yuav ua li cas xaiv cov multifunctional hluav taws xob hluav taws xob hluav taws xob hluav taws xob hluav taws xob hluav taws xob thiab cov kev qhia tsim nyog raws li kev siv hluav taws xob? Yuav ua li cas txiav txim siab qhov tseeb hauv chav kawm thiab kev ntaus nqi tam sim no?
Nws yog ib qho tsim nyog los phim cov tub ntxhais tseem ceeb raws li hluav taws xob thauj khoom thiab cov xwm txheej yuav tsum tau ua. Qhov ntsuas ntsuas tam sim no tuaj yeem suav ua "lub zog ÷ voltage". Rau nruab nrab thiab qis load scararios nrog tsawg dua li lossis sib npaug rau 80a, xws li 10 (60) A) tuaj yeem xaiv tau. Rau kev lag luam siab {{6} Luv Laim xwm txheej nrog tam sim no> 80a, nws yog ib qho tsim nyog los siv nrog ib qho hloov pauv tam sim no (6) ib lub 'ntsuas ntsuas hloov pauv). Qhov tseeb chav kawm yog xaiv raws li cov xwm txheej: siab} lub zog {13} {} (yuam kev tsawg dua lossis sib npaug ntawm 0.5%) kom ntseeg tau tias yog ntsuas tau; Kev ua haujlwm txawv txawv tuaj yeem xaiv chav kawm 1 rau cov nqi sib npaug thiab kev thov; Cov xwm txheej tshwj xeeb xws li lub chaw ua hauj lwm lub chaw ua hauj lwm yuav tsum tau kawm 0.2s. Nyob rau tib lub sijhawm, nws yog ib qho tsim nyog los phim tus voltage. Rau peb-}} Pease Phase Paus yog xaiv, thiab rau high {25} {{.
Kev sib txuas lus ua tau zoo li cas rau cov txheej txheem tswj hwm uas twb muaj lawm? Dab tsi mainstream cov txheej txheem thiab txoj kev txuas tau txhawb nqa?
Kev sib txuas lus kev yoog tau xav tau tsom rau raws tu raws tu proatibility thiab txoj kev txuas. Cov txheej txheem tseem ceeb suav nrog modbus - rtu (adapting rau cov chaw lag luam hauv nroog) xws li qee qhov {- theem metres). Txoj kev sib txuas tau muab faib ua cov xaim thiab wireless: RS485 Wired kev sib txuas tau tus nqi tsawg thiab haum rau Central faib cov xwm txheej hluav taws xob; 4G / NB-IOT Wireless Txuas tsis tas yuav tsum xaim thiab yog haum rau kev cob qhia kev cob qhia lossis cov kev xav tau chaw ua haujlwm tawm tsam lossis chaw ua chaw deb ntsuas kev nyeem ntawv. Thaum kev yuav khoom, nws yog ib qho tsim nyog kom paub meej tias lub ntsuas ntsuas qhov kev tswj hwm uas twb muaj lawm (xws li cov teeb meem tswj hluav taws xob) kom tsis txhob muaj cov ntaub ntawv sib cuam tshuam.
Yuav ua li cas nrog kev sib yuam?
Kev ntseeg tau tuaj yeem lav tau los ntawm kev tiv thaiv qib, kho vajtse kev teeb tsa thiab tsim ua haujlwm. Rau kev lag luam muaj xwm txheej Rau ib qho kev ua txhaum cai, muaj feem thib yuav tsum tau muab rau cov qauv nrog kev tiv thaiv ob zaug (kom tsis txhob muaj roj teeb rau hauv lub neej) Nyob rau tib lub sijhawm, nws yuav tsum muaj kev tshwm sim cov kev ua haujlwm, uas tuaj yeem sau cov ntaub ntawv tsis haum thiab theem poob, muab lub hauv paus rau kev daws teeb meem thiab hluav taws xob rov qab. Qee tus qauv txhawb nqa cov chaw taws teeb thiab chaw ntsuas, txo cov nqi txij nkawm.
