Busbars: hauj lwm, labeling

Log Tsheb yuav tsum tau mus electrically txuas tus neeg hluav taws xob Cheebtsam ua ke.

txhais

hluav taws xob kev twb kev txuas tuav cia koj mus muab tag nrho cov ntsiab ntawm cov installation rau ib tug. Nyob rau hauv qhov tseeb, nws guides, uas nws kuj yog tsawg.

Thaum ib tug ua ke ntawm ob peb tsheb npav ntawm ib tug taw tes sib tham txog kev tsheb nqaj hlau. Raws li ib tug txoj cai, lawv yuav ntsia tau rau hauv lub chaw zov me nyuam, uas kuj pab raws li kev txhawb zog. Nkaum nws nyob rau hauv ib tug tshwj xeeb duct (channel). Vim qhov no nws tiv thaiv ib puag ncig yam tseem ceeb. Busbar yuav tsum nco ntsoov yuav resistant mus rau lub tawm dynamic thiab thermal loads, shock hluav taws xob tam sim no.

busbars yog ua nyob rau hauv ob peb lub versions. Rau lawv faib los ntawm hom Muaj ntau ntau classifications.

By tiav txoj kev paim saj zawg zog thiab txhav log. Lawv txawv hu ua ca thiab tubular. Saj zawg zog log tsheb yog tsis cov. Lawv yuav tsum tsis txhob muaj ib tug high degree ntawm chob. Lub degree ntawm stringing conductors yuav tsum zoo tib yam. Nyob rau hauv tus ntawm kub lub tsheb npav ntev yuav varied. Yog li ntawd, txhav qauv yog nruab nrog ib tug saj zawg zog web, uas yuav tsum tau compensate rau cov kev hloov no. Nyob rau hauv tas li ntawd, lawv yog nruab nrog co dampers.

Nyob rau hauv tas li ntawd, cov log tsheb tej zaum yuav electrically insulated thiab uninsulated. Los ntawm lub npe nws menyuam uas nyob rau hauv thawj cov ntaub ntawv lub log muaj rwb thaiv tsev txheej, thiab lub thib ob - tsis muaj.

Ib suam ntawm log tsheb zoo li tus seem

Tus duab ntawm tus ntoo khaub lig seem ntawm lub tsheb loj tuav raug muab faib mus rau hauv lub nram qab no:

• Tubular.

• Lub.

• Box-puab.

• Ob-txoj kev.

• Peb-txoj kev.

Pav ca tuav ntawm lub ntoo khaub lig seem dissipate tshav kub zoo. Lawv siv yog tsim nyog nyob rau hauv ib tug network uas muaj tam sim no (ntawm 2 txhiab rau 4.1 txhiab amperes). Nyob rau hauv xws li mob, lawv muaj kev cob cog nyob rau hauv pab pawg ntawm cov ob peb daim. Qhov no tas ib ob los sis peb-txoj kev tsheb npav.

Lub busbars muaj ib tug xov tooj ntawm disadvantages:

• Nws yog ib qhov nyuaj rau koj nqa tawm installation ua hauj lwm.

• Lub inductive tam sim no, uas yog faib unevenly.

• Tsis tshua muaj peev xwm los mus tiv txhua yam kev nyuaj siab.

• Txo txias muaj peev xwm.

• Tsis tshua muaj kuj kom luv luv circuits.

Nyob rau hauv lub network, lub thawv los yog tiaj khoom uas yuav siv nrog ib tug voltage ntawm 10-35 kilovolts. Qhov zoo tshaj yog hais tias yuav tubular. Nws muaj ib tug xov tooj ntawm zoo. Nws yog check, zoo tshav kub dissipation. Cov hluav taws xob field nyob ib ncig ntawm nws yog tusyees faib. Los ntawm no nws tsis tshwm sim corona.

Hom ntawm cov ntaub ntawv uas rau manufacturing cov log tsheb

Nyob rau hauv cov ntaub ntawv los ntawm qhov uas cov log tsheb yog manufactured, electrically cais li nram qab no log tsheb:

• Tooj.

• Aluminium.

• Steel.

• Steel-txhuas.

Cov yav tas kev xaiv yog ib tug ntxhais ua los ntawm galvanized steel nyob ntawm tej, ib ncig uas nyob ntawm tej povit ntawm txhuas.

Aluminium log tsheb muaj cov nram qab zoo:

• Resistant rau corrosion.

• Muaj siab hluav taws xob conductivity.

• Tsis tshua muaj ceeb thawj.

• Lawv nqi qis tshaj li lwm hom.

Rau cov siv yas txhuas cim nrog ib tug tsawg kawg nkaus tus nqi ntawm impurities. tsawg-hlau txhuas alloys, magnesium thiab silicon tej zaum yuav siv tau. Ntxiv cov ntsiab yuav ua rau kom lub zog, yooj, elasticity.

Tooj busbars tej zaum yuav muaj nyob rau hauv nws muaj pes tsawg leeg rau 99.9% tooj liab. Tej cov khoom uas muaj sau tias M1. Lug siv hom CMT thiab SHMTV, uas yog ua los ntawm cov pa-free hom. Lawv txawv nyob rau hauv cov neeg kawm ntawv ntawm softness. Thawj ob tsiaj ntawv npav SHMM thiab CMT stands "log tooj liab." Mus ntxiv tsab ntawv "M" qhia tau hais tias tus mos tais, "T" - khoom.

Labeling nrog alternating peb-theem tam sim no

Qhia cov ntsiab ntawm cov hluav taws xob sib pab "lub tswv yim" uas yog qhia nyob rau hauv cov xim thiab cov ntawv los tsheb thauj mus thiab nyob ntawm tej. Lawv tau raug xaiv los ntawm lub caij nyoog. Lawv tswj cov qauv.

Muaj ob txoj kev rau xim-coded log tsheb. Tus thawj assumes uas lub npav yog thov mus rau lub tsheb npav tuav ntawm tus raug theem. Rwb thaiv tsev chaw tsim tshuaj paus siv cov xim txawv. Qhov thib ob mus kom ze nyob rau hauv cov mob uas cov khoom muaj tib xim. Nyob rau hauv tej lub sijhawm, siv kob hluav taws xob kab xev, uas kos tus cim rau ntau theem.

Nyob rau hauv cov ntaub ntawv ntawm peb-theem tam sim no labeling yuav zoo li no:

• Theem "A" yog xim nyob rau hauv daj.

• Theem "B" yog pleev xim rau ntsuab.

• Theem "C" yog pleev xim rau liab.

Npav lub conductors

Cov av neeg xyuas pib sau tias PE. Uas yog ib txwm daj-ntsuab. Xim yog longitudinal kab. Ntxiv mus, cov kev siv ntawm ob xim nyias txwv tsis pub los ntawm GOST. Rau hauv nruab nrab neeg xyuas pib thiab ib tug thib ob (ua hauj lwm) nrog npav N siv xiav xim.

Thaum txuas tiv thaiv lub ntiaj teb conductors thiab ua hauj lwm muab tag nrho peb cov xim. Labeling nyob rau hauv cov ntaub ntawv no zoo li ib tug cwj mem. Explorer sau xiav, thiab nyob rau hauv nws kawg, thiab nyob rau cov pob qij txha yog ua sawb ntawm daj-ntsuab xim. Tam sim no tau thiab ua opposite xim: daj-ntsuab nrog ib tug xiav sawb neeg xyuas pib nyob rau thaum xaus.

Code tsab ntawv

Puas tu yog nyeem daim ntawv, txiav txim hom log, los yog nyob ntawm tej los pab lettering. Ib yam li cov xim, cov tsiaj ntawv muaj lawv transcripts.

Nyob ntawm tej, lub tsheb npav hwj chim ntawm AC deciphered raws li nram no:

• L - xyuas pib-theem network.

• L nrog cov zauv 1, 2 los yog 3 - xyuas pib nyob rau hauv ib tug peb-theem network.

• N - zero neeg xyuas pib (los yog nruab nrab).

• M - nruab nrab neeg xyuas pib.

• PE - grounding neeg xyuas pib (ntaub thaiv npog).

• Cwj mem - ob peb ua ke xoom conductors (kev tiv thaiv thiab ua hauj lwm).

Thaum DC cim yuav raws li nram no:

• L + - zoo neeg xyuas pib (los yog zoo).

• L- - tsis zoo neeg xyuas pib (los yog tsis zoo).

Tag nrho cov ntawv thiab designations yog losis tswvyim dabtsi. Lawv yog tswj hwm los ntawm cov kev cai txais.

Nco ntsoov nws tag nrho cov nyob rau hauv ib zaug yog yooj yim. Tab sis lub tej electrician paub nws tag nrho. Tej labeling yuav txiav txim seb qhov twg thiab dab tsi yog kev cob cog rua. Ib tug txiv neej yuav tsum txaus kom to taub, piv txwv li, dab tsi ib tug log rau hluav taws xob cav tov. Tej zaum nws yuav tsim nyog thaum lub sij hawm kho hluav taws xob thaiv nyob rau hauv lub tsev. Yuav kom nws tom qab tau yooj yim txuas ntxiv qhov chaw.
