Kev tshuaj xyuas qis-Voltage Busbar Safety Distance Standards and Application Technologies

Hauv qis-voltage fais fab faib tshuab, busbars tsis tsuas yog ua lub luag haujlwm tseem ceeb hauv kev xa hluav taws xob, tab sis kuj yog cov khoom tseem ceeb ntawm tus neeg xyuas pib cuam tshuam rau cov khoom siv kev nyab xeeb, kev ruaj ntseg, thiab kev pab lub neej. Nrog rau txoj kev loj hlob ntawm lub zog tshiab, lub zog automation, kev tswj hwm kev lag luam, thiab lub zog cia cov tshuab, kev tsim hluav taws xob rwb thaiv tsev, kev npaj sib nrug, thiab kev teeb tsa tshwj xeeb ntawm qis -voltage busbars tau txais kev pom zoo los ntawm kev lag luam. Qhov tsim nyog kev nyab xeeb nyob deb tsis tuaj yeem tsuas yog txo cov kev pheej hmoo ntawm luv luv circuits, tawm, thiab overheating hauv zos tab sis kuj txhim kho lub sij hawm ntev - kev ntseeg siab ntawm tag nrho cov hluav taws xob busbar.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Qhov kev nyab xeeb ntawm qhov qis -voltage busbars feem ntau yuav tsum muaj kev ntsuam xyuas dav dav txog qhov ntsuas qhov ntsuas hluav taws xob, chav tsev rwb thaiv tsev, ib puag ncig kev teeb tsa, thiab kev khiav haujlwm. Raws li cov kev xav tau ntawm GB / T 7251.1 "Low-voltage switchgear thiab controlgear assemblies," nyob rau hauv daim ntawv thov ib puag ncig nrog cov ntsuas hluav taws xob tsis tshaj 690V, feem ntau pom zoo kom tsis txhob muaj qhov sib txawv ntawm cov busbars tsis pub tsawg tshaj 10mm, thiab qhov tob tob tsis tshaj 14mm. Thaum lub kaw lus ntsuas qhov hluav taws xob tau nce mus rau 1000V, qhov sib txawv ntawm huab cua thiab qhov tob tob yuav tsum tau nce ntxiv kom tau raws li kev sib koom ua ke ntawm rwb thaiv tsev.

 

Nyob rau hauv ib puag ncig kev lag luam uas muaj cov av noo siab, muaj kuab paug siab, lossis cov plua plav siab, cov qauv ntawm lub tsheb npav tsis tuaj yeem ua tau raws sijhawm ntev - yuav tsum tau ua haujlwm. Nyob rau hauv cov xwm txheej zoo li no, cov txheej txheem rwb thaiv tsev, cua sov-shrink tubing, epoxy spraying, los yog cov txheej txheem dip txheej tuaj yeem siv los txhim kho kev ua haujlwm ntawm qhov chaw rwb thaiv tsev thiab txo qhov kev pheej hmoo ntawm arc paug. Hauv cov tshuab hluav taws xob tshiab hluav taws xob, cov tooj liab busbars feem ntau siv nyob rau hauv siab - kis tau tus mob tam sim no, ua rau lawv cov rwb thaiv tsev tiv taus voltage thiab thermal stability tshwj xeeb yog qhov tseem ceeb.

 

Qhov kev nyab xeeb nyob deb ntawm lub busbar thiab cov qauv hlau hauv av kuj yog ib qho tseem ceeb ntawm kev xav. Cov qauv tooj liab liab tau cuam tshuam los ntawm qhov kub thiab txias, lub zog hluav taws xob, thiab cov av noo nyob ib puag ncig thaum ua haujlwm; Yog li ntawd, ib qho kev ncua deb txaus los ntawm lub txee enclosure feem ntau yuav tsum tau txo qhov kev pheej hmoo ntawm kev tawg hauv av. Rau Kev Cai Busbars nrog rwb thaiv tsev kho mob, qhov chaw teeb tsa tuaj yeem raug txo kom tsim nyog, tab sis cov khoom siv rwb thaiv tsev yuav tsum tseem ua tau raws li cov qauv hluav taws xob hluav taws xob sib koom ua ke tsawg -.

 

Hauv cov tshuab hluav taws xob niaj hnub no, kev teeb tsa ntawm cov khoom siv hluav taws xob ncaj qha cuam tshuam rau kev faib tawm tam sim no thiab qhov kub thiab txias. Kev teeb tsa busbar tsis raug tuaj yeem yooj yim ua rau cov nyhuv ntawm daim tawv nqaij thiab cov nyhuv sib thooj, uas ua rau qhov kub tsis zoo hauv zos. Nyob rau hauv kev tsim engineering, ib qho kev sib piv nrog qhov sib txawv yog feem ntau yog siv los txo cov electromagnetic cuam tshuam thiab txhim kho conductivity. Rau siab - cov tshuab tam sim no, Cov Khoom Siv Copper Bus Bars tau siv dav hauv cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab cov tshuab hluav taws xob muaj hluav taws xob vim lawv cov khoom siv hluav taws xob siab thiab cov khoom siv hluav taws xob ruaj khov. Tshwj xeeb tshaj yog nyob rau hauv siab - cov khoom siv fais fab, lub qhov dej zoo - tsim qauv kev txhawb nqa tuaj yeem txo qhov cuam tshuam ntawm cov khoom siv los ntawm luv luv - Circuit Court electrodynamic rog. Feem ntau, qhov sib nrug ntawm qhov kev txhawb nqa insulators yog tswj los ntawm 300mm thiab 500mm los txhim kho tag nrho cov kev ruaj ntseg.

 

Qhov chaw txuas tsheb npav yog ib qho ntawm cov cua sov tseem ceeb- tsim cov ntsiab lus hauv ib qho hluav taws xob. Kev kho tsis raug ntawm kev sib txuas ntawm qhov chaw tuaj yeem yooj yim ua rau muaj kev tiv thaiv kev tiv thaiv, overheating hauv zos, thiab txawm tias ablation. Yog li ntawd, thaum lub sij hawm bolted kev sib txuas, nws yog ib qho tsim nyog los xyuas kom meej qhov chaw tiaj tus thiab tso cai rau qhov chaw rau thermal expansion nyiaj kom tiv taus ntev - lub sij hawm thermal cycling. Rau cov tooj liab- txhuas kev sib txuas cov qauv, ib qho kev hloov pauv bimetallic feem ntau yuav tsum tau ua kom txo tau electrochemical corrosion.

 

Cov txheej txheem khoov kuj yog ib qho tseem ceeb cuam tshuam rau lub neej ntawm busbar. High-txoj kev sib txuas hluav taws xob muaj tseeb, xws li Copper BusBar rau Siemens, feem ntau siv lub vojvoog loj bending txheej txheem los txo cov hluav taws xob hauv cheeb tsam. Lub vojvoog khoov tsim nyog tsis yog tsuas yog pab txhim kho lub zog ntawm lub zog, tab sis kuj txo qhov kev pheej hmoo ntawm cov cua sov hauv zos thaum lub sijhawm ua haujlwm ntev -. Nyob rau hauv lub zog cia systems, them pawg, thiab lub zog tshiab inverter systems, ob qho tib si zoo thiab tsis zoo lub tsheb npav feem ntau yuav tsum tau tiv thaiv kev ua haujlwm siab tam sim no, yog li yuav tsum muaj kev tswj xyuas qhov kub thiab txias. Qee lub tshuab kuj tseem xav tau kev siv cov khoom siv hluav taws xob kub siab tshaj -cov ntaub ntawv rwb thaiv tsev kom ua tau raws li qhov ntev - cov kev xav tau ua haujlwm nyob rau hauv cov xwm txheej nyuaj.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Nrog rau txoj kev loj hlob ntawm kev siv hluav taws xob ntse thiab kev lag luam automation, kev siv cov kev daws teeb meem xws li BusBar ABB, BusBar rau Eaton, thiab BusBar rau Weidmuller tau maj mam txav mus rau kev sib koom ua ke siab dua thiab kev ua haujlwm me me. Kev ua tiav siab dua tam sim no- nqa peev xwm nyob rau hauv qhov chaw txwv tau dhau los ua ib qho kev txhim kho tseem ceeb rau cov tshuab busbar niaj hnub. Yog li ntawd, kev nyab xeeb nyob deb tsim yuav tsum tsis tsuas yog ua tau raws li cov txheej txheem rwb thaiv tsev, tab sis kuj xav txog kev ua kom sov dissipation thiab cov qauv compactness.

 

Nyob rau hauv AC fais fab kis thiab faib teb,AC tsheb npavyog dav siv nyob rau hauv qis -voltage switchgear, tswj txee, thiab fais fab systems; thaum nyob rau hauv lub zog tshiab cia, siab - cov khoom siv hluav taws xob rectifier, thiab kev thauj mus los ntawm kev tsheb ciav hlau, kev rwb thaiv tsev ntawm high-voltage busbars yog nruj dua. Hauv qhov sib piv, qis- cov tsheb npav voltage qhia txog kev lag luam, kev yooj yim ntawm kev teeb tsa, thiab kev ua haujlwm ntev - lub sijhawm ua haujlwm ruaj khov.

 

Cov tshuab busbar niaj hnub no tsis yog cov qauv kev sib txuas yooj yim, tab sis cov khoom siv hluav taws xob tseem ceeb ua ke nrog kev sib txuas, hluav taws xob tawg, rwb thaiv tsev, thiab kev txhawb nqa tshuab. Los ntawm kev tswj xyuas qhov kev nyab xeeb ntawm cov busbars kom zoo, txhim kho cov txheej txheem rwb thaiv tsev, thiab txhim kho cov txheej txheem kev sib txuas, kev ua haujlwm kev nyab xeeb ntawm lub cev tuaj yeem txhim kho tau zoo, thiab cov nqi kho tom ntej tuaj yeem raug txo.
