Kev Ntsuam Xyuas Ntawm Electromagnetic Optimization Principles Rau Tsawg-Inductance Laminated Busbars hauv Rail Transit Thiab High-Power Power Systems

Txoj kev tsheb ciav hlau thiab siab - lub zog hluav taws xob hluav taws xob tau hloov mus rau ntau zaus, kev ntsuas hluav taws xob ntau dua, thiab kev sib koom ua ke ntau dua, ua rau muaj kev nyuaj siab ntau ntxiv hauv lawv qhov chaw nyob hauv electromagnetic. Parasitic inductance, electromagnetic radiation, thiab voltage spikes -vim los ntawm kev hloov pauv sai tam sim no- tau dhau los ua qhov tseem ceeb cuam tshuam rau kev ruaj ntseg.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Hauv kev tsheb ciav hlau traction thiab cov khoom siv hluav taws xob, cov qauv siv hluav taws xob tseem ceeb ua lub luag haujlwm txiav txim siab hauv kev ntseeg tau; busbars tsim rau hluav taws xob locomotives muab kev txhawb nqa ruaj khov rau kev ua haujlwm siab -loading los ntawm optimizing conductive paths thiab structural layouts.

 

Raws li cov khoom siv hluav taws xob hluav taws xob sib xyaw ua ke, cov busbars rau cov hluav taws xob hluav taws xob ua haujlwm tseem ceeb hauv kev xa hluav taws xob thiab cov khoom siv hluav taws xob, ua rau muaj kev cuam tshuam rau qhov system electromagnetic compatibility (EMC).

 

Nyob rau hauv siab - zaus, siab - daim ntawv thov inverter tam sim no, laminated busbars zoo suppress voltage spikes tshwm sim los ntawm siab - zaus hloov los ntawm kev txo lub voj voj voog thiab parasitic inductance.

 

Rau siab -kev hloov pauv ceev tsav, laminated busbars rau IGBT-raws li lub cev muaj zog tsav optimize txoj kev tam sim no los ntawm cov qauv compact, stacked, yog li txhim kho kev ua haujlwm ruaj khov ntawm cov khoom siv fais fab.

 

Hauv DC lub tsheb npav lub zog buffering systems, laminated busbars rau DC - txuas fais fab capacitors txhim kho cov lus teb tsis ntev los no thiab kev ruaj ntseg voltage los ntawm kev txo qhov sib npaug inductance.

 

Hais txog kev teeb tsa capacitor array thiab cov qauv kev sib koom ua ke, laminated busbars tsim los rau capacitor bank mounting structures txhim khu kev ruaj ntseg thaum txhim kho kev faib tawm tam sim no.

 

Hauv siab - zaus vuam thiab cov ntawv siv fais fab, laminated busbars rau siab - zaus vuam fais fab IGBTs zoo txo ​​qhov kev poob qis thiab hluav taws xob cuam tshuam (EMI) hluav taws xob.

 

Hauv kev tshwj xeeb, siab -cov kev ntseeg siab xws li lub tshuab hluav taws xob hauv lub tshuab hluav taws xob, laminated busbars ua qhov tseem ceeb rau kev tsim kho lub teeb yuag thiab qis inductance kom ua haujlwm ruaj khov hauv qhov chaw huab cua.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Structurely, laminated busbars siv ntau- txheej txheej txheej txheej txheej tsim kom ua tiav cov hlau nplaum tshem tawm, ua cov txheej txheem tseem ceeb rau kev txo qis cov kab mob parasitic.

 

Los ntawm kev tsim qauv engineering, kev tsim cov laminated busbars tsom rau kev tswj lub voj voog, ua kom zoo dua cov rwb thaiv tsev interlayer, thiab ua kom muaj kev sib npaug tam sim no.

 

Hais txog kev rwb thaiv tsev thiab kev tiv thaiv, varnished insulated busbars (VIB) txhim kho qhov hluav taws xob tiv taus lub peev xwm los ntawm cov txheej txheej insulating thaum txhim kho kev ntseeg tau raws li kev ua haujlwm nyuaj. Nyob rau hauv tag nrho cov architecture ntawm lub hwj chim systems, busbar kev daws teeb meem rau hluav taws xob faib hluav taws xob tswj lub zog faib thiab txoj kev optimisation, ua lub hauv paus tseem ceeb rau cov lag luam ruaj khov ntawm kev faib tes hauj lwm.

 

Rau cov tshuab hluav taws xob sib xyaw ua ke, cov kev daws teeb meem busbar rau cov khoom siv hluav taws xob siv hluav taws xob siv cov qauv tsim kom ua tiav cov hluav taws xob sib cais thiab kev sib koom ua haujlwm ntawm cov haujlwm sib txawv.

 

Hais txog kev tiv thaiv thiab kev nyab xeeb, customized busbars rau kev tiv thaiv hluav taws xob tuaj yeem tsim kho kom haum raws li cov kev cai tshwj xeeb thiab cov qauv kev tiv thaiv hauv chav kawm.

 

Nyob rau hauv lub realm ntawm kev siv zog tshiab, tooj liab busbars rau lwm lub zog yog dav siv nyob rau hauv lub zog tauj dua tshiab zog hloov dua siab tshiab systems vim lawv zoo heev hluav taws xob conductivity thiab thermal stability.

 

Rau kev lag luam-qib, siab- daim ntawv thov fais fab, laminated busbars rau kev lag luam siv feature txhawb cov qauv tsim uas txhim khu kev vibration thiab kub ua hauj, ua rau lawv tiv taus hnyav ua hauj lwm ib puag ncig.

 

Hauv cov khoom siv hluav taws xob sab hauv ntawm cov khoom siv hluav taws xob precision, laminated busbars rau cov khoos phis tawj ua kom lub zog xa hluav taws xob kom txo qis suab nrov, yog li txhim kho cov teeb liab ruaj khov thiab cuam tshuam kev tiv thaiv.
