VIM LI CAS DC Contactors haum EV MARKET
·Muaj peev xwm los tuav High Currents & Voltages:
DC contactors yog tsim los hloov cov tam sim no thiab voltages heev. Lawv tuaj yeem nqa tau ntau dua 500 Amps thiab raug ntsuas siab dua ntawm 2,000 Volts. Txhawm rau ua tiav qhov no, muaj ntau qhov tshwj xeeb tsim qauv tsim rau hauv cov DC contactors. Piv txwv li, cov tsev nyob yog tsim los ntawm cov resin los yog ceramic thiab hermetically kaw. Inert gasses, xws li hydrogen, sau rau hauv arc chamber. Qhov no pab tiv thaiv oxidation, pab quench arc tam sim no, thiab ua kom tsis kam qis thiab ruaj khov. IP67 kaw cov vaj tsev khaws cov gasses sab hauv thiab tiv thaiv arc to, yog li ua pov thawj los ua qhov kev nyab xeeb zoo ib yam.
·Qhov Sib Nqus Arc Tshuab-Out Feature:
Lwm qhov tshwj xeeb yog hu ua magnetic arc blow-tawm. Cov hlau nplaum tas mus li hauv lub arc chamber tsim ib qho chaw sib nqus thoob plaws cov neeg sib cuag, tsav tsheb thiab ncab cov arc tam sim no tawm sab nraud, pab tua nws sai dua. Arc tam sim no yog tsim thaum kev sib cuag qhib thiab tsis zoo rau cov neeg sib cuag, yog li cov hlau nplaum no ua ke nrog cov roj pab ua kom lub neej ntawm contactor.
·Lub Coil Economizer:
Lub coil economizer yog ib qho tshwj xeeb uas txo cov coil zog thiab cua sov tom qab lub contactor energized. Nws yuav siv sij hawm ntau lub zog los kaw qhov kev hloov ntawm cov contactors muaj zog no, tab sis ib zaug kaw tsis tas yuav tsum tau kaw. Yog li cov khoom siv hluav taws xob xws li PWM (pulse width modulation) pab txo lub zog thiab cua sov thiab.
EV APPLICATIONS RAU DC CONTACTORS
Contactors tuaj yeem nrhiav tau ib lub tsev hauv ntau qhov chaw hauv EV ntiaj teb. Daim ntawv thov rau high voltage DC contactors nyob rau hauv EV qhov chaw suav nrog them nqi thiab ua ntej -them contactors, lub ntsiab thiab pab lub zog contactors, roj teeb disconnect units, them chaw nres tsheb, roj teeb pob, thiab lub zog cia.
