Qib / Kev Tiv Thaiv Equalizing capacitors rau Circuit Court breakers
Kev tiv thaiv vaj huam sib luag sib npaug, feem ntau hu ua grading capacitors, yog siv nyob rau hauv siab -voltage circuit breakers (HV CBs) los faib cov transient rov qab voltage (TRV) sib npaug ntawm ntau qhov kev sib cuag. Cov khoom siv no txuas nrog rau kev sib txuas nrog cov neeg cuam tshuam cuam tshuam, tiv thaiv kev ntxhov siab ntau dhau ntawm ib qho kev sib cuag thiab txhim kho kev cuam tshuam kev ua haujlwm.
Qib capacitors tswj qhov voltagekev faib tawm hauv ntau-unit circuit breakers
Qhov tseem ceeb ntawm Kev Tiv Thaiv Equalizing Capacitor:
Kev ntsuas hluav taws xob:
Thaum cov hluav taws xob sib txuas nrog ntau qhov sib cais ntawm ib theem qhib, cov capacitors xyuas kom tag nrho cov hluav taws xob sib faib sib npaug, tiv thaiv kev sib cuag los ntawm kev ua tsis tiav ntxov.
Transient Suppression:
Lawv txo qhov nce ntawm qhov rov qab voltage (RRRV), txo qhov hnyav ntawm kev hloov, tshwj xeeb tshaj yog nyob rau hauv ntev - kab lossis luv - kab txhaum.
Cov yam ntxwv tsim:
Feem ntau siv hauv MV (Qhov Nruab Nrab Voltage) rau UHV (Ultra-High Voltage) daim ntawv thov, lawv muaj tag nrho - zaj duab xis thev naus laus zis nrog cov khoom siv tawm sab hauv, sab hauv fuses nrog
cov ntsiab lus tsis muaj zog rau kev tiv thaiv, thiab kov - cov ntaub ntawv pov thawj.
Daim ntawv thov:
Feem ntau siv hauv SF6, tuag- tank, thiab lwm yam siab -voltage circuit breakers los tiv thaiv flashover hla qhov sib kis.
Kev cuam tshuam kev ua haujlwm:
Dhau li ntawm qhov ntsuas qhov ntsuas hluav taws xob, lawv tuaj yeem cuam tshuam cov theem nrab arc tam sim no thiab txhim kho lub peev xwm cuam tshuam tag nrho ntawm lub breaker.
