Hauv cov lus qhia txog kev faib hluav taws xob, muaj ob peb lo lus ua rau muaj kev tsis meej pem ntau npaum li "cable tray" thiab "cable ladder." Ob lo lus no feem ntau siv sib pauv ntawm cov duab kos, hauv cov nqi khoom siv, thiab txawm tias hauv cov ntawv teev khoom xa khoom - tsis tas li ntawd lawv piav qhia txog cov khoom sib txawv nrog cov qauv sib txawv, kev thauj khoom sib txawv, thiab cov chaw siv sib txawv. Kev qhia qhov tsis raug txhais tau tias them rau lub peev xwm uas koj tsis xav tau, lossis txhim kho lub kaw lus uas tsis tuaj yeem tswj cov cables uas nws raug thov kom nqa.
Qhov sib txawv ntawm kev ua tau zoo hauv ib kab lus: lub ntaiv cable yog ib qho qauv qhib ntawm ob sab rails txuas nrog los ntawm rungs, ua raucov xov hluav taws xob hnyavhla ntev ntev; lub tais cable yog tsev neeg dav dua uas suav nrog ntaiv, khoom hauv qab, perforated, trough,channelthiabcov tshuab hlau mesh, nrog rau cov tswv cuab zoo li lub tais (khoom khov lossis perforated hauv qab) haum rau cov cabling ntom, sib dua, lossis rhiab rau plua plav.
Phau ntawv qhia no piav qhia txog cov lus siv, qhov sib txawv ntawm cov qauv, thiab - qhov tseem ceeb tshaj plaws - yuav ua li cas xaiv ntawm lawv ntawm ib qhov project tiag tiag.
Ua ntej, cov lus siv: ib lub ntaiv yog ib hom tais
Ua ntej yuav muab piv, yuav tsum tau daws qhov teeb meem ntawm kev faib tawm. Hauv cov qauv uas tswj cov khoom no - NEMA VE 1 hauv North America thiab IEC 61537 thoob ntiaj teb - "cable tray system" yog lub ntsiab lus tseem ceeb, thiab lub tais hom ntaiv yog ib tug tswv cuab ntawm tsev neeg ntawd. Cov pawg tais txheem yog:
- Hom ntaiv - ob txoj hlua sab ntev nrog cov kab sib tshuam
- Hauv qab khov kho - ib daim hlau uas txuas ntxiv mus tas li
- Lub qhov (qhov cua nkag) uas muaj qhov (perforated) — lub hauv qab uas muaj qhov cua nkag los yog qhov chaw
- Hom channel - ib qho profile nqaim, qee zaum hu ua ib txoj kev tsheb ciav hlau
- Hlau mesh (lub pob tawb) - welded hlau grid, ib qho ntxiv tsis ntev los no
Yog li thaum ib tug engineer hais tias "cable tray," lawv yuav txhais tau tias tag nrho tsev neeg lossis - hauv cov lus siv niaj hnub - ib tug tswv cuab zoo li lub tais nrog lub hauv qab, tsis zoo li lub ntaiv. Tsab xov xwm no siv qhov sib txawv ntawm kev siv: cable ladder piv rau cov tais-hom systems nrog cov hauv qab khov kho lossis perforated, uas yog qhov sib piv uas tsav cov kev txiav txim siab specification.
Ua cas ibntaiv cable is
Ib lub ntaiv cable muaj ob txoj kab C-profile uas txuas nrog cov rungs transverse ntawm qhov sib nrug tsis tu ncua - feem ntau yog 250 mm lossis 300 mm qhov sib nrug - nrog rau cov rungs tiv taus-welded lossis mechanically swaged rau cov rails. Qhov kev tsim kho qhib yog nws qhov tshwj xeeb engineering feature.
Tus qauv tsim ua raws li cov cables uas nws siv. Cov cables fais fab hnyav - cov khoom noj hluav taws xob nruab nrab, cov hlau loj uas hla ntu - tsim cua sov thaum thauj khoom, thiab cov qauv qhib rung cia cov cua sov ntawd tawm mus tas li raws li qhov khiav tag nrho. Cov qauv tsim uas muaj cua nkag kuj muab cov chaw teeb tsa ntawm txhua rung, yog li cov cables tuaj yeem ruaj ntseg ntawm txhua qhov chaw yam tsis tas yuav tho qhov, thiab nws ua rau txhua lub cable pom tseeb rau kev tshuaj xyuas thiab taug qab raws txoj kev.
Raws li kev tsim kho, tus ntaiv ua haujlwm zoo li lub thav duab zoo li truss. Cov hlau C-profile tob tob tiv taus kev khoov thiab kev sib ntswg, uas txhais tau tias muaj kev txhawb nqa ntev dua thiab kev ntsuas siab dua ib ntu dua li cov tais uas muaj qhov hnyav zoo sib xws. Qhov no yog vim li cas cov ntaiv yog qhov kev xaiv tsis raug rau cov chaw tsim hluav taws xob, cov chaw hloov pauv, kev lag luam hnyav thiab, nce ntxiv, kev faib hluav taws xob ntawm chaw khaws ntaub ntawv, qhov twg cov xov hlau loj yuav tsum tau txhawb nqa yam tsis muaj kev txhawb nqa ntau dhau.
Cov lus qhia txog ntaiv ib txwm muaj — siv cov hlau kub-dip galvanized ua tus qauv — khiav ntawm 200 mm txog 900 mm hauv qhov dav, hauv tus qauv 3 m thiab 6 m ntu ntev, nrog rau qhov siab ntawm sab rail ntawm 100 mm lossis 150 mm thiab rung pitch ntawm 250 mm lossis 300 mm. Cov ntsuas kev thauj khoom tau luam tawm ib qhov dav, rung pitch thiab kev txhawb nqa qhov sib nrug raws li NEMA VE 1 lossis IEC 61537 cov txheej txheem xeem.
Lub kaw lus hom tais yog dab tsi
Cov tswv cuab hom tais — hauv qab khov kho thiab muaj qhov perforated — sib koom tib tsev neeg ntawm sab ntug tab sis nqa ib qho hauv qab txuas ntxiv lossis muaj qhov perforated ntawm cov ntug es tsis yog cov theem qhib.
Lub tais hauv qab ruaj khov yog lub qhov kaw. Nws muab qib siab tshaj plaws ntawm kev tiv thaiv rau cov cables sab hauv, tiv thaiv lawv ntawm cov khib nyiab poob, cov kua dej ntws thiab kev sib cuag tsis tu ncua, thiab nws tuav cov nplaim taws cable zoo dua hauv cov xwm txheej hluav taws thaum nruab nrog lub hau thiab cov teeb meem hluav taws. Nws qhov tsis zoo yog thermal: cua sov los ntawm cov cables muaj zog tsis muaj txoj kev khiav tawm tsuas yog los ntawm cov hlau, yog li cov txheej txheem hauv qab ruaj khov xav tau kev suav cov cable puv thiab tsis tshua siv rau cov voj voog fais fab hnyav.
Lub tais uas muaj qhov (qhov cua nkag) yog qhov sib haum xeeb: lub hauv qab uas muaj qhov cua nkag uas tso cai rau kev tso cua sov ib nrab thaum tseem muaj cov cables. Nws yog lub zog ua haujlwm rau kev sib xyaw ua ke ntawm lub zog thiab kev tswj hwm, sib npaug ntawm cov cua ntws nrog kev tiv thaiv, thiab nws feem ntau siv rau hauv cov tsev lag luam, cov chaw tsim khoom thiab kev faib khoom lag luam dav dav uas cov cables muaj ntau tab sis cov cables loj me me.
Vim tias cov tswv cuab ntawm lub tais faib cov khoom thauj thoob plaws ib daim ntawv txuas ntxiv dua li cov theem sib cais, lawv zoo rau cov xov hlau me me ntau - cov cuab yeej siv, kev tswj hwm, kev sib txuas lus thiab cov teeb pom kev zoo - qhov twg suav cov xov hlau tseem ceeb dua li qhov hnyav ntawm ib tus neeg hlau. Qhov kev pauv pauv yog tias qhov hauv qab txuas ntxiv cov khoom siv, uas ua rau cov kab ke hom tais hnyav dua thiab, ib 'meter', kim dua li cov ntaiv sib npaug - thiab qhov hnyav ntawd tshwm sim hauv cov kev xav tau kev txhawb nqa.

Cov kev nkag siab yuam kev feem ntau
"Ib lub ntaiv ua tau txhua yam uas lub tais ua tau." Tsis yog li ntawd. Cov ntaiv zoo heev nrog cov xov hluav taws xob tab sis tsis muaj kev txwv - hmoov av, cov khib nyiab thiab cov dej ntws mus txog, thiabcov xov hlau tswj me metuaj yeem poob ntawm cov theem yog tias tsis tau txhawb nqa tas mus li.
"Lub tais yeej ib txwm muaj zog dua li ntaiv." Qhov sib txawv feem ntau yog qhov tseeb rau ib qho hnyav. Lub thav duab zoo li lub ntaiv nqa cov khoom hnyav dua ntawm qhov ntev dua li lub tais hauv qab ntawv uas muaj cov khoom zoo sib xws.
"Hauv qab khov txhais tau tias cov cables nyob txias dua." Tsis yog. Cov tais hauv qab khov ntes tau cua sov; cov cai ntawm IEC thiab NEMA fill-ratio muaj nyob rau ntawm qhov no. Yog tias qhov kev khiav yog cua sov tswj hwm, lub ntaiv qhib lossis lub tais perforated uas muaj cua zoo yog qhov kev xaiv zoo dua.
"Koj tuaj yeem sib tov lawv tau yooj yim." Koj ua tau, nrog rau cov reducers thiab adapters, thiab ntau qhov project ua tau - ib lub Hoobkas yuav siv cov ntaiv rau nws cov khoom noj fais fab thiab cov tais perforated rau nws cov circuits tswj. Qhov tseem ceeb yog qhia txhua ntu rau yam nws nqa, thiab nrhiav cov khoom siv hloov pauv los ntawm tib lub chaw tsim khoom kom lub kaw lus tseem ua haujlwm mechanically thiab electrically.
Cov lus qhia tshwj xeeb
Txoj cai xaiv yooj yim heev: cia lub cable txiav txim siab. Cov cable fais fab hnyav uas ntev ntev nrog cua sov kom poob rau ntawm lub ntaiv cable. Cov xov hlau me me uas xav tau kev tswj thiab kev tiv thaiv taw rau lub kaw lus hom tais.
