LW3-10 yangaphandle High Voltage SF6 Circuit Breaker
Irhasi ye-SF6 ibalasele ngokugquma kunye nokucima i-arc, kwaye inentsebenzo engcono. Ezo zixhobo zilukhokelo olusakhulayo kwihlabathi liphela.
I-LW3-10 I II III ichwetheza ngaphandle i-SF6 yesekethe eqhekezayo yamkela igesi ye-SF6 njengokucima kwakhona kunye nokufakela izixhobo eziphakathi, ezisetyenziselwa i-arc yokuzicima ngokuzicima ithiyori. indlela yokusebenza kunye nohlobo lwe-III lwendlela yokusebenza kwe-electromagnetic. Zonke izixhobo zinokusebenzisana nomzimba ophule kakuhle.
