Daga masu hankali kan muhimmin magance, mafi girman molecule da ke cikin SF6 suna da mahimmanci a matsayin yanayin da ya fi ƙarin don magance. Saboda haka, switchgear da ake amfani da SF6 ya bukata muhimmin magance da muhimmin material, inda an amfani da compounds da structures masu kyakkyawan don inganta cewa magance an buga a shekarun 0.5% baya. Amma switchgear da ba suka da SF6 tana bukata muhimmin magance, amma muhimmin material da process da ake amfani da su na iya kasance da cewa switchgear da ake amfani da SF6. Wasu daga cikin gas-gas mai kyau da ba suka da SF6 suna da kyakkyawan da ya fi ƙarin da material da ake amfani da su don magance, wanda ke taimaka wajen inganta options da za a iya amfani da su.

Daga masu hankali kan tsariyar arc, SF6 shine gas da tsariyar arc mai kyau. Ba da bayan idan an yi decomposition, tana sauye electrons da ke cikin arc plasma, wanda ke taimaka wajen karɓe arc da tarihi - wanda ke taimaka wajen inganta tsariyar arc a cikin halayen high-voltage, high-current. Tsariyar arc da ake amfani da SF6 gas-free gases suna da muhimmiyar tsariyar arc da ya faru; wasu daga cikin formulations masu kyakkyawan suna iya inganta tsariyar arc da ya dace da SF6, amma wasu suna da tsariyar arc da ya fi ƙarin da tarihin da ya fi ƙarin.

Daga masu hankali kan cost, SF6 gas tare da kyakkyawan da ya fi ƙarin. Amma saboda muhimmin magance da tsariyar system da ake amfani da ita, cost overall da SF6 switchgear tana da kyakkyawan da ya fi ƙarin. Don SF6 gas-free switchgear, wasu daga cikin gas-gas mai kyau da ba suka da SF6 suna da R&D costs da ya fi ƙarin, amma tana da kyakkyawan da ya fi ƙarin, amma tare da technological advancements da economies of scale, cost su tana dole da kullum da za su iya zama competitive da SF6 equipment a cikin zamani.

Daga masu hankali kan intervals maintenance, SF6 switchgear tana da kyakkyawan da ya fi ƙarin saboda stability da gas, inda an bukatar comprehensive gas testing da inspection da kayan aiki a shekarun 3 zuwa 5 a cikin halayen aiki. Amma intervals maintenance da SF6 gas-free switchgear tana da muhimmin stability da conditions da ake amfani da su; wasu daga cikin units za su iya buƙatar gas monitoring da performance assessments da ya fi ƙarin, wanda ke taimaka wajen karɓe intervals maintenance zuwa shekarun 1-2.

Daga masu hankali kan breakdown voltage characteristics, SF6 tana da breakdown voltage da ya fi ƙarin da hawa a cikin electric fields uniform, wanda ke taimaka wajen inganta high voltages da ba ya buga. Breakdown voltage da SF6 gas-free gases tana da muhimmin composition da pressure, wanda ke taimaka wajen inganta evaluation careful during design da application.

Daga masu hankali kan application scope, SF6 switchgear tana da amfani a cikin high-voltage da extra-high-voltage power systems, inda tana da dominance a substations da high-voltage supply systems da large industrial facilities. SF6 gas-free switchgear tana da amfani a cikin medium- da low-voltage systems, amma tare da technological maturation, tana dole da kullum da za su iya zama high-voltage applications. Amma a cikin high-voltage, high-capacity scenarios, validation da refinement additional tana da buƙata compared to SF6 solutions.

Daga masu hankali kan gas detection methods, SF6 tana da amfani a cikin gas chromatography ko infrared absorption techniques - methods mature da accuracy detection da ya fi ƙarin. Don SF6 gas-free gases, saboda compositions da ya fi ƙarin da diverse, detection methods tana da muhimmin variety da tana dole da kullum. Inda some SF6 detection approaches tana iya adapt, new detection technologies tailored to specific gas components tana da buƙata don enable accurate da rapid gas analysis.
