Portable 120A Loop Resistance Tester

Portable 120A Loop Resistance Tester

MOEORW-W5010P yog ib qho khoom siv me me micro-ohm ntsuas ntsuas tau tsim los rau ntawm - qhov chaw tiv thaiv qhov ntsuas siab ntawm -voltage hloov kev sib cuag loops thiab qis -cov khoom siv hluav taws xob tsis zoo. Txais DC voltage nco kev ntsuas tau teev tseg hauv GB763 thiab ua raws li DL / T 845.4-2004 kev lag luam specification, lub tsev tso zis adjustable siab DC tam sim no mus txog 120A kom tshem tawm cov hlau lead tiv thaiv cuam tshuam thiab paub precision micro-ohm nrhiav kom tau. Ua-hauv loj- muaj peev xwm rov them tau lithium roj teeb txhawb kev sim teb yam tsis muaj AC fais fab sab nraud; compact dimension thiab lub teeb yuag ua kom yooj yim tuav lub lag luam rau substation txij nkawm, switchgear Hoobkas tuaj xyuas thiab teb commissioning scenarios. Tag nrho cov kev ntsuas ntsuas ua raws li plaub-wire Kelvin xeem txoj cai los cais cov excitation tam sim no thiab voltage sampling terminals, dastly txhim kho qhov tseeb rau ultra-tsawg kuj specimens.

3.1 Hardware & Structure Design

1. Integrated high-density lithium battery pack inside the enclosure, eliminating external mains connection restriction for outdoor field inspection; puv - xim LCD npo nrog kho lub teeb nraub qaum thiab ntim tswj kom muaj ntau haiv neeg ntawm - thaj chaw saib thiab lub suab nyeem tom qab ntsuas tiav.2. Independent dual-terminal layout: C1/C2 rau siab- cov zis tam sim no, P1/P2 rau qis-cim voltage sampling, nruj nreem cais excitation thiab sampling circuits kom ua raws li plaub-wire ntsuas tus qauv; kev sib tw sib tw ua rau cov xim -coded tuab / nyias cais cov xaim rau kev sib txuas ntawm thaj chaw.3. Ntau- txheej tsim- nyob rau hauv kev tiv thaiv Circuit Court: qhib- Circuit Court detection, overtemperature automatic shutdown tiv thaiv, txawv txav kev sib txuas ntse interlock, zam cov khoom puas los ntawm miswiring los yog overheating.

3.2 Kev ntsuas kev ua tau zoo

1. Ntau- qib tam sim no xaiv los ntawm 30A txog 120A sib tw segmented resistance testing range, realizing full coverage from micro-ohm to 20mΩ resistance ntsuas; customized kuaj ncua sij hawm los ntawm 1s mus rau 60s optimizes thermal tsub zuj zuj nyob rau hauv lub sij hawm ntev - lub sij hawm siab - tam sim no tso zis thiab txo cov khoom cua kub poob.2. Ultra- siab 0.1μΩ daws teeb meem ntxiv rau ± (0.5% RD+2μΩ) precision ua kom ntseeg tau tias muaj kev ntseeg siab ntawm kev sib cuag me me ntawm qhov siab -voltage breaker contacts thiab switch junctions.

3.3 Tom qab-test Data Management Value

1. Hauv zos cia siab tshaj 200 qhov kev xeem cov ntaub ntawv nrog nws pib hnub-raws li cov ntaub ntawv naming thiab editable custom serial number rau batch asset management of tested equipment.2. Plaub qhov sib txawv ntawm cov ntaub ntawv xa tawm: U-disk ib- nyem export (txuag raws li TestData.txt), Bluetooth wireless luam ntawv, QR code tiam (max.50 cov ntaub ntawv ib QR rau mobile scanning), thiab ntawm -cov ntaub ntawv keeb kwm tshawb nrhiav nrog nplooj ntawv -up/down flip, sib ntsib cov ntaub ntawv chaw ua haujlwm archiving thiab teb tej thaj chaw deb synchronization.

Tus tester ua rau DC voltage poob (plaub-hlau Kelvin) ntsuas: qhov DC siab tam sim no raug txhaj rau hauv cov qauv kuaj ntawm C1 / C2 tam sim no terminals, thaum P1 / P2 voltage terminals khaws cov me me voltage poob generated thoob plaws qhov ntsuas tsis kam; ua-hauv MCU suav cov nqi tiv thaiv raws li Ohm Txoj Cai (R=U/I). Sib cais tam sim no & voltage terminals tshem tawm qhov kev ua haujlwm tsis zoo ntawm qhov kev sim ua thiab cov khoom siv clamping, uas yog qhov tseem ceeb lav ntawm μΩ- qib ntsuas precision.

• Kev lag luam hluav taws xob hluav taws xob: Ntawm- qhov chaw tu & niaj hnub tshuaj xyuas ntawm siab-voltage AC / DC Circuit Court breakers, disconnecting keyboards, GIS txee conductive loops nyob rau hauv substations.· HV khoom manufacturing: Hoobkas tuaj xyuas thiab tiav- khoom kuaj rau siab -voltage transit.gear, cov khoom siv hluav taws xob tshiab, cov khoom siv hluav taws xob: Kev ntsuas kev tiv thaiv siab ntawm -tam sim no hloov kev sib cuag nyob rau hauv cua fais fab converters, locomotive siab-voltage txee Cheebtsam.· Third- tog kuaj cov tsev kawm ntawv: niaj hnub xyuas ntawm tsawg-tsis kam conductive Cheebtsam rau cov khoom siv fais fab kev soj ntsuam.
