Hluav taws kub-Resistant Bus Duct

Hluav taws kub-resisting busbar trunking yog lub kaw lus busbar trunking system nrog hluav taws kub tshwj xeeb-cov khoom tiv taus, feem ntau yog siv rau kev xa hluav taws xob hauv cov tsev lossis cov chaw lag luam. Nws lub luag haujlwm tseem ceeb yog tswj xyuas cov khoom siv hluav taws xob ib txwm muaj rau qee lub sijhawm raws li cov nplaim taws thiab qhov kub thiab txias thaum muaj hluav taws kub, ua kom muaj kev ua haujlwm tsis tu ncua ntawm cov khoom tseem ceeb xws li hluav taws kub - cov cuab yeej sib ntaus sib tua thiab cov tshuab xwm txheej ceev. Cov hauv qab no muab cov ncauj lus qhia ntxaws ntxaws los ntawm cov ntsiab lus xws li kev txhais, cov yam ntxwv ntawm cov qauv, cov kev xav tau ntawm kev ua haujlwm, cov ntawv thov scenarios, cov txiaj ntsig tseem ceeb, thiab kev teeb tsa thiab kev saib xyuas:

Hluav taws kub-resisting busbar trunking yog raws li qhov zoo tib yam busbar trunking, thiab los ntawm cov ntaub ntawv tshwj xeeb thiab cov qauv tsim, nws ua rau lub busbar trunking tswj nws cov rwb thaiv tsev kev ua tau zoo thiab tam sim no - nqa peev xwm ntawm rated tam sim no rau ib lub sij hawm (feem ntau 1h, 2h, 3h, thiab lwm yam) nyob rau hauv high {10s ~ 70℃(kub) 10 ℃ ), tsis muaj luv luv Circuit Court, grounding, los yog rwb thaiv tsev tsis ua hauj lwm, yog li xyuas kom meej lub hwj chim tsis tu ncua mus rau qhov tseem ceeb circuits.

Cov qauv tsim hluav taws kub- tiv thaiv busbar trunking tsom rau "tiv thaiv nplaim taws, ncua kev hloov hluav taws xob, thiab tiv thaiv hluav taws xob hluav taws xob." Nws cov khoom tseem ceeb suav nrog:

1. Conductor System feem ntau

siab -conductivity tooj liab busbars (T2 tooj liab) los yog aluminium busbars yog siv, nrog rau kev kho los tiv thaiv - oxidation los xyuas kom meej tam sim no - nqa peev xwm thiab txhua yam muaj zog. Cov neeg siv hluav taws xob sib cais los ntawm hluav taws kub- cov ntaub ntawv tiv thaiv cov ntaub ntawv tiv thaiv (xws li mica daim kab xev, ceramicized silicone roj hmab, siab -kub resistant fiberglass daim ntaub, thiab lwm yam). Cov ntaub ntawv no tsis hlawv lossis decompose ntawm qhov kub thiab txias, tswj lawv cov kev ua haujlwm rwb thaiv tsev.

2. Hluav taws kub-resistant Outer Plhaub

Lub plhaub sab nrauv feem ntau siv ob npaug - txheej lossis cov qauv sib xyaw: txheej txheej sab hauv yog cov pob txha hlau (xws li galvanized steel phaj, stainless hlau phaj), thiab txheej txheej los yog txheej txheej yog ntim nrog hluav taws kub- tiv taus thiab tshav kub- cov ntaub ntawv insulating (xws li aluminium silicate paj rwb, lub teeb yuag, cib, thiab lwm yam). Qee cov khoom lag luam kuj ntxiv cov hluav taws kub-cov ntawv tiv thaiv mica rau sab hauv ntawm lub plhaub sab nraud, ua rau ntau yam teeb meem hluav taws. Lub plhaub sab nrauv yuav tsum muaj kev sib khi zoo, siv hluav taws xob- tiv taus intumescent sealing strips thiab fireproof sealant los kaw qhov sib txuas sib txuas thiab tiv thaiv kev nkag ntawm cov nplaim taws thiab siab - cua kub gases.

3. Cov ntsiab lus txuas

Cov pob qij txha (xws li kev sib txuas ncaj nraim thiab ceg sib txuas) yog cov ntsiab lus tsis muaj zog hauv kev tiv thaiv hluav taws thiab yuav tsum siv hluav taws kub - cov khoom sib txuas. Qhov no yog ua tiav los ntawm kev npog nrog hluav taws- tiv thaiv mica daim kab xev, txhim kho hluav taws- lub tes tsho tiv taus, lossis siv hluav taws kub hnyiab- cov ntsaws ruaj ruaj kom ntseeg tau tias cov pob qij txha muaj qhov hluav taws kub ua haujlwm zoo ib yam li cov qauv tseem ceeb thaum muaj hluav taws.

Qhov kev ua tau zoo ntawm hluav taws kub-cov ducts busbar tiv taus yuav tsum ua raws li cov qauv hauv tebchaws. Cov qauv tseem ceeb suav nrog:

• GB 7251.2-2013 "Low-voltage switchgear thiab controlgear assemblies - Ntu 2: Cov kev cai tshwj xeeb rau busbar trunking systems (busbar ducts)": Cov txheej txheem no txhais cov hluav taws kub-resistant busbar ducts, qhia lawv tus qauv tsim, xeem txoj kev, thiab cim cov cai.
• GB/T 19216.21-2021 "Cables thiab optical fibers nyob rau hauv cov nplaim taws - Ntu 21: Vertical nplaim propagation test rau ib leeg-strand insulated xov hlau thiab cables - Test apparatus": Cov qauv no qhia txog tej yam kev mob rau cov nplaim taws kuaj (xws li nplaim taws kub, lub sij hawm kub hnyiab, thiab kub nce).

• Kev Ntsuas Hluav Taws Xob: Muab faib los ntawm lub sijhawm hluav taws kub mus rau 1h, 2h, 3h, thiab lwm yam. (1h thiab 2h feem ntau siv) kom tau raws li qhov xav tau sib txawv.
• Cov Teebmeem Teebmeem: Thaum lub sijhawm kuaj, tus neeg xyuas pib yuav tsum tiv taus cov nplaim taws ncaj qha ntawm qhov ntsuas kub (piv txwv li, 750℃± 50 degree, 950℃± 50 degree) thaum qhov ntsuas tam sim no (lossis 1.1 npaug ntawm qhov ntsuas tam sim no) yog siv. Tus neeg xyuas pib qhov kub thiab txias (tsis tshaj qhov txwv) thiab kev tiv thaiv hluav taws xob (tsis pub tsawg dua 0.5MΩ) raug saib xyuas.
• Kev ncaj ncees: Tom qab kev sim, lub busbar casing qhia tsis muaj qhov tseem ceeb deformation, cov conductors tsis muaj luv luv Circuit Court los yog grounding faults, thiab nws muaj peev xwm mus nqa tau cov rated tam sim no.
   

Hluav taws kub- cov busbars resistant feem ntau yog siv rau hauv cov chaw uas xav tau siab heev rau kev tiv thaiv hluav taws xob hluav taws xob, tshwj xeeb nrog rau:

• High-cov tsev nce siab: Cov khoom siv hluav taws xob rau hluav taws kub elevator, teeb pom kev kub ceev, thiab cov pa luam yeeb hauv cov tsev nyob thiab chaw ua haujlwm;
• Cov chaw pej xeem: Cov khoom siv hluav taws xob kub ceev hauv tsev kho mob (chav ua haujlwm, ICU), subways, tshav dav hlau, thiab chaw nres tsheb ciav hlau;
• Kev lag luam thiab kev lag luam: Cov twj tua hluav taws thiab kev khiav tawm thaum muaj xwm txheej ceev hauv cov khw loj loj, cov chaw khaws ntaub ntawv, cov chaw tswj xyuas xwm txheej ceev, thiab cov nroj tsuag tshuaj;
• Cov chaw tshwj xeeb: Tsev khaws puav pheej, archives (cov khoom siv tiv thaiv kab lis kev cai), nuclear fais fab nroj tsuag pab chaw, thiab lwm yam.

Muab piv rau cov hluav taws kub ib txwm muaj- cov kab hluav taws xob tiv taus lossis cov kab hluav taws xob zoo tib yam, hluav taws kub -cov hluav taws kub hnyiab tau muaj cov txiaj ntsig hauv qab no:

1. High Current Transmission Capacity: Tus neeg xyuas pib loj hla- ntu ntu thiab cov cua kub zoo heev, nrog lub peev xwm nqa tau ntau txhiab amperes, haum rau siab -load fais fab faib hauv siab- nce vaj tse thiab chaw loj;

2. Kev txhim kho yooj yim thiab kev tu: Txhawb nqa kab rov tav, ntsug, thiab ceg kev teeb tsa, ua kom yooj yim installation. Tom qab- kev txhim kho kev txhim kho tsuas yog yuav tsum tau kuaj cov rwb thaiv tsev thiab kev sib txuas, tshem tawm qhov xav tau loj - hloov pauv;

3. Sib npaug hluav taws kub tiv thaiv thiab kev faib hluav taws xob kev ua tau zoo: Thaum ua tau raws li qhov yuav tsum tau muaj hluav taws kub, nws tuav cov impedance tsis tshua muaj thiab tsis tshua muaj cov yam ntxwv ntawm busbar trunking, kom ntseeg tau ntev - lub sijhawm ua haujlwm ruaj khov;

4. Kev Siv Qhov Chaw Siab: Cov qauv uas nyob ib puag ncig yog qhov chaw tsawg dua li cov tais cable, haum rau cov qauv siv hluav taws xob sib txuas ntawm cov tsev niaj hnub.

1. Kev yuav tsum tau ua:

• Xyuas kom lub casing sab nraud yog tag nrho kaw. Kev sib txuas qhov khoob yuav tsum tau ntim nrog cov hluav taws kub - tiv thaiv sealant kom tsis txhob muaj nplaim taws nkag;
• Kev kho lub bracket yuav tsum siv hluav taws kub- tiv taus thiab corrosion- cov ntaub ntawv tiv taus, nrog qhov sib txawv raws li cov qauv tsim tshwj xeeb los tiv thaiv kev sib tsoo ntawm qhov hluav taws kub;
• Ceg interfaces thiab lub taub hau davhlau ya nyob twg yuav tsum siv cov chaw tsim khoom qub - muab hluav taws kub - cov khoom siv tiv taus. Kev hloov pauv tsis raug cai raug txwv nruj heev.

2. Cov Ntsiab Lus Tseem Ceeb:

• Tsis tu ncua (tsawg kawg ib xyoos ib zaug) kuaj cov rwb thaiv tsev (Ntau dua lossis sib npaug ntawm 20MΩ ntawm chav tsev kub);
• Tshawb xyuas lub casing rau deformation, corrosion, kev laus ntawm lub sealing strips, thiab kev ncaj ncees ntawm rwb thaiv tsev txheej;
• Tsis txhob khawb qhov hluav taws kub - cov txheej txheem rwb thaiv tsev tiv thaiv lossis ua rau cov qauv casing puas thaum lub sijhawm tu. Hu rau cov chaw tsim khoom rau kev kho yog tias tsim nyog.

Hluav taws kub-resisting busbar trunking yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob faib hluav taws xob ua ke nrog kev sib kis tam sim no, hloov tau yooj yim, thiab hluav taws kub- tiv taus kev ntseeg tau. Los ntawm cov khoom siv tshwj xeeb thiab cov qauv tsim, nws muab cov khoom siv hluav taws xob txuas ntxiv rau kev tiv thaiv hluav taws thiab cov txheej txheem xwm txheej ceev nyob rau hauv hluav taws kub. Nws yog siv dav hauv cov tsev niaj hnub, cov chaw pej xeem, thiab lwm qhov chaw tseem ceeb, thiab yog ib qho tseem ceeb ntawm kev txhim kho kev ruaj ntseg hauv tsev.
