Lub luag haujlwm tseem ceeb ntawm lub siab -voltage DC contactor yog los tswj cov kev hloov ntawm circuits. Hauv DC Circuit Court, tus contactor ua tiav txoj haujlwm no los ntawm nws cov kev sib cuag sab hauv thaum nws xav tau kev txiav lossis txuas lub voj voog. Tsis zoo li AC contactors, DC contactors yuav tsum kov yeej qhov tsis muaj qhov xoom xoom- hla qhov taw qhia rau DC tam sim no thaum txiav, yuav tsum tau ua kom muaj lub ntsej muag zoo nkauj dua - tua tsim.
Cov khoom tseem ceeb ntawm lub siab -voltage DC contactor muaj xws li electromagnet, ib qho kev sib cuag, thiab cov qauv siv tshuab. Thaum lub contactor txuas rau hauv Circuit Court, lub electromagnet generates ib magnetic teb uas tam sim no ntws, attracting cov neeg mus kaw, yog li ua kom tiav lub Circuit Court. Thaum nws yog ib qho tsim nyog los txiav lub voj voog, lub tshuab electromagnet yog de-energized, thiab cov neeg sib txuas nyob rau hauv qhov kev txiav txim ntawm cov springs, cuam tshuam qhov tam sim no. Nyob rau hauv cov txheej txheem no, cov hlau ntshiab hauv EV relay bracket yog ib qho tseem ceeb ntawm cov txheej txheem kev txhawb nqa ntawm lub tshuab electromagnetic, thiab nws cov permeability thiab mechanical zog ncaj qha cuam tshuam rau electromagnet cov lus teb ceev thiab kev ruaj ntseg ntawm nws cov quab yuam attraction.
Nyob rau hauv qhov siab -voltage DC ib puag ncig, hluav taws xob arc tsim thaum sib cuag tawg yog qhov tseem ceeb cuam tshuam rau tus contactor lub neej. Txhawm rau tswj cov arc kom zoo, niaj hnub siab -voltage DC contactors feem ntau siv cov kab sib txuas ua ke nrog sib nqus arc tshuab lossis hydrogen arc extinguishing thev naus laus zis. Hauv qhov no, kev ua haujlwm ntawm Hluav Taws Xob Pure Hlau Stamping rau EV DC Contactor ncaj qha cuam tshuam rau qhov sib xws ntawm electromagnetic drive mechanism txoj haujlwm. High-purity ntshiab hlau stampings tuaj yeem muab cov hlau nplaum qis dua thiab siab dua saturation magnetic flux ntom, yog li txhim kho tus contactor lub peev xwm tawg.
Kev tsim ntawm siab -voltage DC contactors yuav tsum tau ua tib zoo xav txog cov hauv qab no:
Ua ntej, kev ua haujlwm rwb thaiv tsev. Txij li thaum siab -voltage DC contactors yuav tsum tiv taus high voltages (feem ntau specifications ntawm 450V mus rau 1000V los yog siab dua), qhov tsim ntawm lawv cov rwb thaiv tsev system yog ib qho tseem ceeb heev. Feem ntau, siab - cov ntaub ntawv rwb thaiv tsev zoo yog siv sab hauv, thiab qhov kev ncua deb thiab kev tshem tawm yog tsim los kom muaj kev nyab xeeb thiab kev ntseeg siab nyob rau hauv siab -voltage tej yam kev mob.
Thib ob, arc kuj. Arc tiam yog ib qho kev sib tw loj hauv high -voltage DC circuits. Optimizing cov ntaub ntawv tiv tauj (xws li siv nyiaj -raws li alloys los yog tungsten tooj liab tiv tauj) thiab arc - tua chamber qauv tuaj yeem txo qhov kev yaig ntawm kev sib cuag los ntawm lub zog arc, ncua kev pab cuam lub neej. Lub caij no, lub nplhaib hlau rau EV DC Relay, uas yog ib qho tseem ceeb ntawm cov qauv kev sib txuas ntawm lub tshuab hluav taws xob thiab kev sib txuas lus, cuam tshuam rau kev ruaj ntseg ntawm arc - tua qhov sib txawv vim nws qhov tseeb qhov tseeb thiab lub zog txhua yam.
Thib peb, tshav kub dissipation thiab thermal tswj. Nyob rau hauv high voltage thiab siab tam sim no tej yam kev mob, contactors yuav tsim ib tug loj npaum li cas ntawm Joule tshav kub. Cov qauv tsim feem ntau suav nrog cov kev siv hluav taws xob zoo thiab cov txheej txheem cua sov hauv lub casing kom ntseeg tau ntev - lub sijhawm ua haujlwm ruaj khov. HVDC Relay skeleton, ua los ntawm cov hlau ntshiab, tsis tsuas yog ua haujlwm ntawm cov hlau nplaum sib nqus, tab sis kuj koom nrog hauv kev tsim hluav taws xob. Lub siab - cov pob txha pob txha hlau zoo pab txo qhov kub thiab txias hauv zos.
Plaub, compact qauv thiab kev co kuj. Automotive daim ntaub ntawv tso cai nruj me ntsis ntawm tus contactor qhov loj thiab kev co kuj. EV HVDC Contactor Pure Iron Bracket, los ntawm precision stamping, muab cov neeg kho tshuab muaj zog txaus nyob rau hauv qhov chaw txwv thaum ua kom ruaj khov huab cua sib txawv hauv lub tshuab hluav taws xob. High- stamping precision zam tsis muaj kev ntseeg siab xws li cov ntsiab lus tseem ceeb lossis kev koom tes tsis txaus.
Hauv cov tshuab hluav taws xob, siab -voltage DC contactors yog siv los tswj siab -voltage DC circuits hauv daim phiaj hluav taws xob, pab ua kom muaj kev nyab xeeb ntawm kev hloov hluav taws xob thiab kev tiv thaiv overload, thiab txhim kho daim phiaj kev ruaj ntseg. Tshwj xeeb tshaj yog nyob rau hauv DC hloov tau yooj yim kis tau tus mob thiab lub zog cia systems, txhim khu kev qha kev khiav hauj lwm ntawm tus contactor yog ncaj qha cuam tshuam rau kev nyab xeeb kev khiav hauj lwm ntawm tag nrho cov fais fab chaw nres tsheb.
Hauv cov tsheb fais fab, lub roj teeb tswj qhov system yog ib qho ntawm cov tseem ceeb ntawm kev nyab xeeb. High-voltage DC contactors yog siv los tswj kev sib txuas thiab kev sib txuas ntawm lub pob roj teeb thiab lub cev muaj zog, ua kom muaj kev nyab xeeb thaum them thiab tawm. Ntshiab hlau stamping qhov chaw rau EV relays yog dav siv nyob rau hauv lub ntsiab Circuit Court contactors thiab pre-them relays. Lawv cov khoom siv purity thiab stamping precision ncaj qha cuam tshuam rau tus contactor lub peev xwm tawg thiab kev ntseeg siab hauv kev vibration. Nrog rau qhov nce ntxiv ntawm 800V siab -voltage platforms hauv lub tsheb hluav taws xob, cov kev xav tau siab dua tau muab tso rau ntawm qhov ntev ntev thiab kev ua haujlwm sib nqus ntawm cov hlau ntshiab hlau stamping qhov chaw.
