CF4 Gaz Karışımlarında Delinme Geriliminin Ölçülmesi ve Hesaplanması

Tetrafluoromethane (CF4), güç anahtarlama ve gaz izoleli kesicilerin endüstriyel uygulamalarında kullanılmasına rağmen güçlü bir sera gazıdır. Bu dezavantaj, CF4'ün Argon, Nitrojen gibi çeşitli gazlar ile karışımları yapılarak giderilir. Gazların dielektrik özelliklerinin irdelenmesi, delinme gerilimlerinin ölçülmesi ile mümkündür. Oluşturulan deney düzeneğinde 1mm ile 5mm arasında farklı elektrot açıklıklarında, CF4 gaz karışımlarının delinme gerilimleri ölçülmüştür. CF4+SF6 ve CF4+Argon gaz karışımlarının ölçülen delinme gerilimleri literatürdeki sonuçlar ile karşılaştırılarak, hem ölçüm düzeneği hem de ölçüm metodu doğrulanmıştır. Ardından, literatürde henüz yayınlanmamış olan CF4+N2 gaz karışımının delinme gerilimleri farklı elektrot aralıklarında ölçülmüştür.

Measurement and Calculation of Breakdown Voltages in CF4 Gas Mixtures

Tetrafluoromethane (CF4) has found industrial applications in power switching and gas insulated circuit breakers although it is considered to be a powerful greenhouse gas. This disadvantage can be overcome by mixing CF4 with gases like Argon and Nitrogen. In order to investigate the dielectric properties of the gases, the breakdown voltages must be measured. An experimental system is used to measure the breakdown voltages of CF4 gas mixtures for different electrode separation between 1 mm and 5mm. By comparing the measured breakdown voltages of CF4+SF6and CF4+Argon gas mixtures with the corresponding values in the literature, the measurement method and experimental system are verified. Then, the breakdown voltages of CF4+N2 gas mixture is measured, which is lack in the literature.
