Yuav ua li cas xaiv tooj liab Busbar nyob rau hauv siab thiab qis voltage Switchboards?

Yuav ua li cas xaiv tus tooj liab busbar nyob rau hauv high thiab low-voltage switchboards? Xav paub ntau ntxiv raws li hauv qab no:

1.Copper busbars yog siv dav hauv cov khoom siv hluav taws xob

Tshwj xeeb tshaj yog nyob rau hauv tag nrho cov khoom siv hluav taws xob, feem ntau, tooj liab busbars yog siv nyob rau hauv W, U, V, theem busbars thiab PE busbars nyob rau hauv lub hwj chim faib khoom.

Copper kab, tseem hu ua tooj liab busbar los yog tooj liab busbar, yog ib tug ntev neeg xyuas pib ua los ntawm tooj liab nrog ib tug rectangular los yog chamfered (piv txwv li) rectangular cross-section (tam sim no feem ntau siv rounded tooj liab kab kom tsis txhob tip discharge), uas plays lub luag hauj lwm nyob rau hauv conveying. tam sim no thiab txuas cov khoom siv hluav taws xob hauv ib lub voj voog.

Copper busbars feem ntau yog cim nrog theem xim ntawv cim lossis pleev xim rau theem xim, W theem tooj liab coated nrog "liab" xim, PE busbar tooj liab coated nrog "daj thiab ntsuab" ob-xim teb, V theem tooj liab kab yog pleev xim rau "ntsuab" "xim, U theem tooj liab kab yog pleev xim rau "daj" xim.

2.Kev xaiv ntawm tooj liab busbars nyob rau hauv high-voltage switchboards

High-voltage switchboards tooj liab busbars hla ntu xaiv yuav tsum tau ua kom tau raws li ob txoj cai.

(1) kom tau raws li qhov ntsuas tam sim no

(2) kom tau raws li lub sijhawm luv luv tiv thaiv tam sim no.

3.Cov tooj liab busbars ntawm lub load peev xam xam

peb yuav tsum nkag siab tias kev teeb tsa ntawm tooj liab hauv cov hluav taws xob hloov hluav taws xob tau muab faib ua ob hom, tiaj tus thiab ntsug, ntsug load peev xwm yog me ntsis siab dua lub tiaj tus, yog li lub tsheb npav tseem ceeb ntawm lub txee faib khoom feem ntau yog ntsug. Tseem muaj tooj liab busbars, tooj liab hlau load peev xwm kuj yuav hloov nrog lub ambient kub, qhov twg peb siv ambient kub ntawm 35 degrees Celsius. Nyob rau hauv qhov sib txawv ambient kub, lub peev xwm load tau los ntawm lub rooj yuav tsum tau muab multiplied los ntawm qhov kho kom haum rau txawv ambient kub, lub load peev xwm nyob rau hauv txawv ambient kub, qhov kub thiab txias, lub load peev xwm yuav txo.

4. Kev tiv thaiv Busbar

Txhawm rau tiv thaiv cov kab hluav taws xob hluav taws xob thiab cov hluav taws xob hloov hluav taws xob, ua ntej ua qhov ntsuas hluav taws xob ntawm cov cables thiab xaiv cov khoom siv rwb thaiv tsev uas ua tau raws li qhov yuav tsum tau muaj kev nyab xeeb hluav taws xob. Hauv cov tshuab hluav taws xob uas tsis tshua muaj hluav taws xob, peb feem ntau siv cov khoom siv xws li cov raj hollow lossis sheathed raj los tiv thaiv cov hluav taws xob tsawg los ntawm ib puag ncig cuam tshuam, txo cov kev cuam tshuam sab nraud, thiab txhim kho kev ua haujlwm ntawm cov khoom siv hluav taws xob.

High voltage bus thiab low voltage bus yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob, thiab lawv cov kev xaiv tshwj xeeb cuam tshuam ncaj qha rau tag nrho cov haujlwm ntawm lub zog hluav taws xob. Yog li ntawd, thaum xaiv cov high-voltage thiab low-voltage busbars, kev xaiv yuav tsum yog raws li qhov sib txawv voltage theem, tam sim no loads, thiab load cov ntaub ntawv, thaum lub sij hawm kom paub meej kev lag luam thiab kev nyab xeeb. Tsuas yog nyob rau hauv txoj kev no peb tuaj yeem ua kom muaj kev ua haujlwm zoo thiab muaj kev nyab xeeb ntawm lub tshuab hluav taws xob thiab tsis txhob muaj kev sib tsoo tsis tsim nyog.
