Grounding thiab Fais Distribution Busbars hauv Rail Transit & Traction Substations

Rau 750V thiab 1500V DC rail traction systems, busbar yuav tsum tswj fault{2}}tam sim no txoj kev, thermal nce, mechanical rog, thiab rwb thaiv tsev clearance tib lub sij hawm. Lub Rail Transit Grounding Busbar tsis yog ib txoj hlua tooj liab xwb: nws tus ntoo khaub lig-section, kev sib koom ua ke, mounting geometry, kev kho saum npoo, thiab cov txheej txheem insulating yuav tsum tau sib phim rau traction rov qab thiab grounding architecture txhais rau lub installation. TS EN 50122-1 hais txog kev nyab xeeb hluav taws xob, av av, thiab rov qab Circuit Court rau kev teeb tsa kev tsheb ciav hlau ruaj khov, thaum EN 50122-2 hais txog cov teebmeem tam sim no hauv DC traction systems.

 

 

 

Lub traction substation faib DC lub zog los ntawm siab -cov neeg xyuas pib tam sim no thaum muab cov kev tswj hwm rau kev tiv thaiv kev sib txuas thiab qhov txhaum tam sim no. Cov hauv av thiab hluav taws xob xa hluav taws xob busbars yog li ntawd muaj cov hluav taws xob sib txawv txawm tias lawv tau tsim los ntawm cov qib tooj liab zoo sib xws.

 

Rau Rail Transit Grounding Busbar, kev tshuaj xyuas tus tsim yuav tsum pib nrog txoj kev ua tiav tam sim no es tsis yog qhov nominal system voltage. Tus engineer yuav tsum txhais:

 

750V lossis 1500V DC qhov hluav taws xob qhov hluav taws xob thiab kev sib koom ua ke ntawm rwb thaiv tsev.
Kev ua haujlwm tsis tu ncua, suav nrog ambient -kub derating.
Cov yav tom ntej luv luv -circuit tam sim no, lub sijhawm ua txhaum, thiab tiv thaiv- lub sijhawm tshem tawm cov khoom.
Copper cross-section, busbar spacing, thiab parallel-configuration conductor.
Kev sib koom ua ke, bolt preload, thiab tiv tauj -qhov chaw.
Grounding thiab bonding topology raws li traction installation tsim.
Creepage thiab clearance nrug ntawm lub siab tshaj plaws kev khiav hauj lwm voltage.

Rau cov tooj liab loj, qhov yuam kev me me tuaj yeem sib sau hla ntau cov ntsiab lus sib txuas. Qhov lub suab, khoov lub kaum sab xis, qhov dav dav thiab cov ntsiab lus txuas txuas yuav tsum yog li ntawd yuav tsum tau tswj los ntawm tib lub datum system.

 

 

 

Lub busbar tuaj yeem ua tiav nws qhov txuas ntxiv - qhov yuav tsum tau muaj tam sim no thiab tseem ua tsis tiav thaum lub sijhawm luv luv. Lub zog hluav taws xob ntawm cov khoom sib txuas ua ke nce nrawm nrog kev ua txhaum tam sim no, ua rau kev txhawb nqa qhov sib txawv, kev taw qhia tus neeg xyuas pib, thiab lub zog ceev ntawm qhov tsim hluav taws xob.

 

Rau ib qho yooj yim thaum uas tig mus -conductor kev npaj, electromagnetic quab yuam yog kwv yees li proportional rau cov khoom ntawm instantaneous tam sim no:

 

qhov twg kuv sawv cev tam sim no thiab d sawv cev rau tus neeg xyuas pib sib nrug.

 

Qhov tseeb luv luv -circuit design yuav tsum siv lub system-tshwj xeeb yav tom ntej txhaum tam sim no, waveform, conductor geometry thiab tiv thaiv lub sij hawm tshem tawm. Ib qho txhaum 25 kA thiab 50 kA txhaum tsis tuaj yeem raug kho raws li qhov yooj yim ob - lub sij hawm kev teeb tsa kev tsim kho vim tias lub ncov asymmetrical tam sim no tuaj yeem dhau RMS luv - tus nqi hluav taws xob.

 

Vim li no, daim duab busbar yuav tsum txhais:

Txhawb qhov sib nrug hauv mm.
Copper thickness thiab dav hauv mm.
Luv-circuit tam sim no hauv kA RMS.

Cov ntaub ntawv: FAI / PPAP Qib 3 qhov xav tau.
Traceability: cov ntaub ntawv ntau, ntau lawm batch, thiab soj ntsuam cov ntaub ntawv.

 

Qhov kev txhim khu kev qha tshaj plaws ntawm kev yuav khoom txuas txhua qhov yuav tsum tau ua rau ntsuas tus yam ntxwv, kev tshuaj xyuas thiab kev lees paub. Qhov no tiv thaiv cov ntsiab lus xws li "high conductivity," "fire resistant," los yog "heavy-duty" los ntawm kev hloov cov kev txwv engineering.

 

 

Cov ntaub ntawv dab tsi uas ib txwm xav tau rau PPAP Qib 3 traction busbar ntau lawm?

PPAP Qib 3 ib txwm xav tau cov ntaub ntawv tsim qauv, cov txheej txheem ntws, PFMEA, kev tswj hwm txoj kev npaj, qhov tshwm sim, cov ntaub ntawv / cov ntaub ntawv kev ua tau zoo, MSA qhov twg siv tau, cov qauv piv txwv, thiab PSW. Cov neeg siv khoom - tshwj xeeb PPAP cov cai yuav tsum ua ntej.

 

Ntev npaum li cas T1 tus qauv siv rau kev cai C1100 tooj liab busbar?

T1 lub sij hawm nyob ntawm geometry, cov cuab yeej yuav tsum tau, thiab kev kho saum npoo. Tej yam yooj yim laser- txiav los yog CNC prototypes tuaj yeem tsim tau yam tsis muaj kev vam meej, thaum lub busbars nyuaj yuav tsum tau txhim kho cov cuab yeej ua ntej tus neeg sawv cev T1 qhov chaw muaj.

 

Ua li castooj liab busbarplating thickness txheeb xyuas thaum lub sij hawm tsim khoom?

Tin, npib tsib xee, lossis nyiaj plating thickness tuaj yeem kuaj xyuas siv XRF lossis lwm txheej txheej uas siv tau- txoj kev tuab. Kev ntsuas qhov chaw yuav tsum suav nrog thaj chaw sib cuag thiab cov chaw tsim khoom sawv cev, nrog rau kev lees txais txwv tau teev tseg ntawm daim duab kos lossis kev yuav khoom tshwj xeeb.
