Cov ntsiab lus
Peb cov khoom tshiab, NVS1-12 series sab hauv tsev high-voltage nqus Circuit Court breakers yog siv rau switchgears nyob rau hauv 12kV fais fab system, raws li ib tug tswj thiab tiv thaiv chav tsev ntawm hluav taws xob equipments nyob rau hauv industrial thiab mining lag luam, fais fab nroj tsuag thiab substations. Vim yog qhov tshwj xeeb zoo ntawm lub tshuab nqus tsev vacuum breaker, nws yog qhov tshwj xeeb tshaj yog tsim rau kev ua haujlwm nquag uas yuav tsum tau ntsuas ua haujlwm tam sim no, lossis qhov chaw uas qhov luv-circuit tam sim no tawg ntau zaus. Lub Circuit Court breaker txais kev sib xyaw tsim ntawm kev khiav hauj lwm mechanism thiab Circuit Court breaker lub cev. Ob leeg yog cov qauv pem hauv ntej thiab nraub qaum, uas yog nrog kev txhim khu kev qha interlocking muaj nuj nqi. Lub Circuit Court breaker tuaj yeem siv los ua ib qho chaw ruaj khov. Nws tseem tuaj yeem nruab nrog lub tsheb chassis mus rau hauv ib lub tawb nqa khoom.
