Kev soj ntsuam ntawm High-Voltage Contact Systems hauv New Energy Tsheb: Lub luag haujlwm tseem ceeb ntawm DC Contactors

Raws li lub zog tshiab tsheb (NEVs) txuas ntxiv mus rau qhov siab -voltage platforms-xws li ntawm 400V thiab 800V mus txog 1000V- qhov yuav tsum tau muaj rau kev nyab xeeb thiab kev ntseeg siab ntawm lub tsheb hluav taws xob tau nce siab. Tawm tsam qhov backdrop no, siab -voltage DC contactors ua haujlwm tseem ceeb hauv kev tswj hwm; lawv ua lub luag haujlwm tseem ceeb ntawm kev hloov siab -voltage circuits thiab ua kom muaj kev nyab xeeb kev sib cais, ua haujlwm tau zoo raws li lub hauv paus tseem ceeb ntawm siab -kev ntseeg siab ntawm hluav taws xob tiv tauj tshuab.

 

 

 

High-voltage DC contactors tuaj yeem nkag siab tias cov khoom siv hluav taws xob hloov hluav taws xob tsim los ua haujlwm nyob rau hauv cov xwm txheej ntawm high voltage thiab siab tam sim no; lawv lub luag haujlwm tseem ceeb yog kom muaj kev nyab xeeb thiab cuam tshuam cov hluav taws xob hluav taws xob. Thaum cov txheej txheem relays txaus rau qis -voltage systems, high-voltage NEV systems xav tau cov cuab yeej tshwj xeeb uas muaj cov txheej txheem rwb thaiv tsev thiab arc- tua muaj peev xwm.

 

Los ntawm qhov kev xav ntawm lub cev, lawv cov laj thawj kev ua haujlwm sawv cev rau qhov txuas ntxiv ntawm cov ntsiab lus sib tiv tauj zoo -tshwj xeeb, ua tiav qis- poob, hloov pauv tam sim no ruaj khov los ntawm kev sib koom ua ke ntawm cov khoom siv hluav taws xob thiab cov khoom siv tshuab.

 

Tsis tas li ntawd, nyob rau hauv kev tsim hluav taws xob, cov cuab yeej no ua raws li qhov tseem ceeb ntawm cov kab hluav taws xob sib txuas, cuam tshuam ncaj qha rau lub tsheb lub zog xa hluav taws xob thiab kev txwv kev nyab xeeb.

 

 

High-voltage DC contactors feem ntau muaj cov kauj, armature, ib qho kev tiv tauj, thiab ib qho arc-extinguishing structure. Lawv txoj haujlwm yog nyob ntawm cov txheej txheem ntawm electromagnetic actuation:

 

Energizing lub kauj generates ib magnetic teb uas tsav cov neeg kho tshuab qauv.

Lub armature txav mus kaw lossis qhib cov neeg sib cuag.

Lub arc - tua hluav taws xob tua hluav taws xob arc thaum lub caij hluav taws xob tawg.

 

Kev sib cuag cov qauv tsim feem ntau suav nrog ntau yam qauv tsim kom haum raws li qhov sib txawv tam sim no thiab kev pabcuam lub neej.

 

Piv txwv li, cov qauv kev sib cuag nrog cov qauv tseem ceeb yog qhov tseem ceeb ntawm cov khoom siv dag zog thiab kev ua haujlwm ruaj khov, qhov siab - cov ntawv thov kev ntseeg siab feem ntau cia siab rau cov qauv sib txuas.

 

 

Hauv siab -voltage DC systems, cov ntaub ntawv tiv tauj ncaj qha txiav txim siab lub cuab yeej siv lub neej thiab muaj peev xwm tawg. Cov khoom siv feem ntau suav nrog cov nyiaj -raws li thiab tooj liab-raws li alloys, nrog rau lub hom phiaj tseem ceeb ntawm kev ntsuas hluav taws xob tiv thaiv kev tiv thaiv arc yaig.

 

Hauv cov ntawv thov siab - kawg, cov nyiaj dawb huv tau siv dav ntawm cov khoom siv hluav taws xob tseem ceeb vim lawv cov kev coj ua tau zoo, thaum cov nyiaj hlau sib tiv tauj siv alloying los txhim kho hnav tsis kam thiab tiv thaiv kev sib cuag vuam. Nyob rau hauv cov qauv precision, cov khoom siv nyiaj sib cuag rivets yog ua haujlwm los txhim kho kev sib txuas ntawm cov neeg kho tshuab kev ruaj ntseg, ua kom muaj kev ntseeg siab thaum nquag, ntev - lub sijhawm ua haujlwm.

 

Tsis tas li ntawd, cov ntsiab lus nyiaj tiv tauj feem ntau yog siv rau hauv qhov chaw sib txuas tseem ceeb kom txo qis kev sib cuag thiab txhim kho lub zog xa mus.

 

 

 

High-voltage DC systems ua rau muaj kev sib zog arcs thaum lub sijhawm tsis sib txuas-ib qho tseem ceeb cuam tshuam rau kev nyab xeeb. Yog li ntawd, lub arc - tua hluav taws xob ua haujlwm ua tus qauv tsim qauv.

 

Nyob rau hauv cov txheej txheem no, nyiaj hluav taws xob tiv tauj cov ntaub ntawv yog siv los txhim kho arc tsis kam thiab conductivity stability, txo cov khoom poob vim ablation los ntawm cov khoom optimization.

 

Meanwhile, nyob rau hauv siab - zaus hloov tej yam kev mob, hluav taws xob lub caij nplooj ntoos hlav tiv tauj cov qauv muab ruaj khov kev sib cuag, kom ntseeg tau raws li kev sib cuag tiv thaiv lub sij hawm ntev.

 

Nyob rau hauv ib puag ncig kev khiav hauj lwm nyuaj, daim ntawv thov ntawm cov nyiaj sib tiv tauj tshuab tau txhim kho lub cev thermal stability thiab hluav taws xob lifespan.

 

 

Kev ua tau zoo ntawm siab -voltage DC contactors feem ntau yog txiav txim siab los ntawm cov kev txwv hauv qab no:

 

Rated voltage thiab tam sim no muaj peev xwm
Luv - lub sij hawm overload muaj peev xwm
Txhaum lub peev xwm tam sim no
Hluav taws xob thiab mechanical lifespan

 

Hais txog kev tiv thaiv kab ke, kev ruaj ntseg ntawm cov hluav taws xob tiv tauj ncaj qha txiav txim siab siab -voltage ruaj ntseg ciam teb ntawm lub tsheb.

 

Tsis tas li ntawd, kev sib cuag nrog cov nyiaj hlau ua tau zoo tshaj plaws rau kev sib cuag vuam hauv cov xwm txheej cuam tshuam nrog cov dej ntws siab, yog li txhim kho tag nrho cov kev ntseeg tau.

 

 

Nyob rau hauv lub siab -voltage systems ntawm lub zog tshiab tsheb, cov khoom no yog dav siv nyob rau hauv traction roj teeb circuits, charging systems, thiab auxiliary zog tswj systems.

 

Nyob rau hauv lub roj teeb tswj systems, lawv tswj lub ntsiab Circuit Court tswj thiab ua ntej - tiv thaiv nqi; hauv kev them nyiaj, lawv tswj cov kev hloov ntawm kev them nqi / tso tawm thiab kev sib cais txhaum.

 

Hauv cov ntawv thov nyuaj no, kev sib cuag hluav taws xob tsis yog tsuas yog ua cov khoom siv hluav taws xob xwb tab sis kuj tseem yog cov ntsiab lus tseem ceeb rau kev tswj hwm kev nyab xeeb.

 

Tsis tas li ntawd, hluav taws xob kev sib cuag hloov cov qauv ua kom yooj yim hloov cov logic hla ntau lub voj voog hauv qhov system- qib tswj, txhim kho kev tswj hluav taws xob yooj yim.

 

 

 

Nrog rau kev siv dav dav ntawm 800V thiab ntau dua voltage platforms, siab -voltage DC contactors,Khoom Siv Nyiajyog evolving mus rau miniaturization, siab dua kev ntseeg, thiab ncua kev pab cuam lub neej. Kev ua kom zoo tsis tu ncua ntawm cov khoom siv tshuab, arc- cov qauv tua hluav taws, thiab cov txheej txheem kev sib cuag ua kom muaj kev ruaj ntseg txawm tias nyob rau hauv kev ua haujlwm hnyav.

 

Saib tom ntej, siab -voltage contact thev naus laus zis yuav txuas ntxiv hloov zuj zus nyob ib puag ncig lub zog siab ceev thiab muaj kev ruaj ntseg ruaj khov, tsim nws tus kheej ua ib qho tseem ceeb ntawm cov tshuab hluav taws xob tsav tsheb rau lub zog tshiab.
