  • SF6-alternative gases for application in gas-insulated

    Mar 20, 2018The environmental problems caused by greenhouse gases have received unprecedented attention. Sulfur hexafluoride (SF 6), which is the preferred gas for use in gas-insulated switchgear (circuit breakers, disconnect switches, etc. for high-voltage electrical circuits), has a very high global warming potential, and there is a large international effort to find alternative gases.

    Apr 15, 2019C 4 F 7 N (fluorinated nitrile) gas mixture has been utilized as the gas insulating medium to replace the most greenhouse gas SF 6 (sulphur hexafluoride). Nowadays, there are few reports on the toxicity mechanism of C 4 F 7 N and studies on the application risk of C 4 F 7 N is insufficient. In this paper, we carried out acute toxicity tests for C 4 F 7 N gas systematically.

    Gas insulated switchgears occupy an important position in the power system. But the partial discharge would occur because of insulation defect, PD will lead to the GIS insulation damage after a long time, and will lead to serious consequences without treatment in time, therefore, the PD detection is particularly important. PD is detected by its secondary physical phenomena, including the
