Kev Tshuaj Xyuas Kev Ntseeg Siab Hluav Taws Xob & Cov Khoom Siv Siab Tshaj Plaws Engineering Framework

1. Cov Lus Qhia Tseem Ceeb: Tus Nqi Zais Cia ntawm Kev Ua Tsis Tau Zoo ntawm Lub Txuas

Rau cov neeg tsim cov vaj huam sib luag tswj kev lag luam, cov neeg sib koom ua ke ntawm cov txheej txheem automation, thiab cov tes hauj lwm faib hluav taws xob, kev so ntawm lub qhov rooj kawg ntawm lub qhov ntsia hlau tsis yog tsuas yog teeb meem kev saib xyuas niaj hnub xwb - nws yog qhov ua rau lub kaw lus tswj tsis ua haujlwm. Qhov xwm txheej no yog qhov ua rau lub sijhawm ua haujlwm tsis tau npaj tseg, cov lej ua yuam kev phantom PLC, thiab kev hla dhau ntawm cov voj voog kev nyab xeeb. Kev sib txuas hluav taws xob yog nyob ntawm lub zog clamping tas mus li thoob plaws lub neej ntawm cov khoom siv.

Kev txo qhov torque ntawm cov ntsia hlau hauv cov thaiv qhov rooj nce-cage feem ntau tshwm sim thaum lub zog clamping poob ntau dua 20% ntawm qhov chaw tsim khoom pib 0.8–1.2 N·m cov lus qhia tshwj xeebThaum qhov kev puas tsuaj ntawm lub tshuab no tshwm sim, nws ua rau tus neeg coj hluav taws xob nkag mus. Yog li ntawd, qhov kev tiv thaiv kev sib cuag nce ntxiv los ntawm qhov ua haujlwm zoo heev 10 mΩ. Qhov kev tiv thaiv no tsim cov cua sov hauv zos (I²R poob) uas ua rau qhov kub kawg nce siab tshaj 105 ° C, ua rau lub rwb thaiv tsev ib puag ncig puas tsuaj loj heev.

> 20% Lub zog clamping poob qis

> 10 mΩ Kev Tiv Thaiv Kev Sib Txuas Lus Tseem Ceeb

> 105°C Kev puas tsuaj ntawm rwb thaiv tsev

Ib lub thaiv hluav taws xob uas kub dhau hauv lub chaw tswj lub cev muaj zog 480 V tuaj yeem ua rau muaj qhov teeb meem loj heev, ua rau cov khoom sib ze puas tsuaj thiab ua rau NFPA 70E arc-flash teeb meem nrog lub zog teeb meem tshaj 8 cal/cm². Txhawm rau kom txo tau cov kev pheej hmoo no, kev siv lub moj khaum kev tshuaj xyuas kev ntseeg siab hluav taws xob yog qhov tseem ceeb heev. Lub moj khaum no ua tib zoo saib xyuas cov kev ntsuas clamping, cov khoom siv, thiab kev tswj hwm thermal uas cais cov thaiv hluav taws xob qib kev lag luam tiag tiag thiab cov khoom siv sib txuas.

Ua ib lub tuam txhab ua lag luam uas tau ntawv pov thawj raws li ISO 9001: 2008, peb Lub Tuam Txhab Lub Tsev Nplooj Ntawv (ISO9001: 2008, SGS, UL, 2010) qhia txog peb txoj kev cog lus rau cov qauv nruj no. Kev tshuaj xyuas soj ntsuam peb lub hauv paus tseem ceeb uas txiav txim siab seb tus neeg tsim khoom puas tsim nyog ua tus neeg muag khoom hauv kev lag luam:

Kev Tuav Ruaj Khoov Torque thiab Kev Ruaj Ntseg ntawm Clamping-Force: Lub hauv paus kev tsim kho tshuab ntawm kev sib txuas uas tsis tshua muaj kev tiv thaiv.
Rising-Cage Khoom Hardness thiab Conductor Creep Tsis kam: Cov txheej txheem metallurgical tiv thaiv kev lwj ntawm lub zog clamping dhau sijhawm.

2. Kev Tshawb Fawb Txog Kev Siv Tshuab thiab Kev Tsim Khoom Siv

2.1 Kev Khaws Cia Torque thiab Kev Ruaj Ntseg ntawm Clamping-Force

Cov thaiv davhlau ya nyob twg uas nce siab, xws li cov uas tau tshwm sim hauv peb cov kev qhia dav dav Cov Khoom Siv Terminal Blocks (Ntsia Hlau / Tsis Muaj Ntsia Hlau / Pluggable / DIN Rail), siv lub tawb uas muaj lub hau ntsia hlau loj heev (feem ntau yog tooj dag, C36000, H58) uas tuav tus neeg xyuas hluav taws xob kom nruj rau ntawm lub bar tam sim no uas muaj tin-plated. Kev so ntawm lub zog yog ib qho txheej txheem insidious uas tshwm sim hauv peb qhov xwm txheej tseem ceeb:

Kev Sib Txhuam Los Ntawm Oxidation: Tus coefficient ntawm kev sib txhuam ntawm cov xov ntsia hlau nce ntxiv vim yog qhov micro-oxidation dhau sijhawm (μ > 0.25 vs. thawj 0.15), txhais tau tias siv lub zog torque tsis txhais ua lub zog clamping lawm.
Kev Txuas Ntxiv Tus Neeg Coj Mus Los: Cov xov hlau conductors lub cev deformed nyob rau hauv lub clamping pressure. Piv txwv li, txhuas conductors tuaj yeem creep 0.1 mm/xyoo ntawm 20 N/mm² siab.
Kev Sib Txawv ntawm Kev Nthuav Dav Thermal: Kev hloov pauv kub tas li (hloov pauv txhua hnub ntawm 20 ° C mus rau 60 ° C hauv cov vaj huam sib luag kev lag luam kaw) ua rau muaj kev nthuav dav sib txawv ntawm tooj dag (α = 19 × 10⁻⁶ / ° C) thiab tooj liab (α = 17 × 10⁻⁶ / ° C), maj mam thim rov qab lub hau ntswj.

Yuav kom tawm tsam qhov no, peb cov khoom siv dav dav siv Cov ntsia hlau hlau uas muaj nickel-plated (M3, HRS, torque 0.8–1.2 N·m) ua ke nrog cov ntsia hlau tshwj xeeb serrated (DIN 6798, 0.5 hli tuab). Cov ntsia hlau no lub cev tom rau hauv qhov chaw ntawm tus neeg xyuas pib, ua haujlwm ua lub caij nplooj ntoos hlav dynamic uas tswj lub zog clamping ≥ 80% ntawm nws tus nqi pib txawm tias tom qab 1,000 lub voj voog kub heev (−40 ° C txog + 105 ° C). Yog li ntawd, kev tiv tauj tsis kam yog tuav nruj me ntsis ntawm
