  • Circuit breakers classified by interrupting medium

    Sep 22, 2020Gas circuit breakers generally employ SF6 (sulfur hexaflouride) as an interrupting and sometimes as an insulating medium. In “single puffer”mechanisms, the interrupter is designed to compress the gas during the opening stroke and use the compressed gas as a transfer mechanism to cool the arc and to elongate the arc through a grid (arc

  • Experimental study on the effect of O 2 on the discharge

    Oct 18, 2019Sulfur hexafluoride (SF6), the most widely used insulating medium in power equipment, is a high-greenhouse effect gas. The use of alternative eco-friendly gases as an insulating medium is of great significance to the green development of the power industry. C5 perfluoroketone (1,1,1,3,4,4,4-heptafluoro-3-(trifluoromethyl)-2butanone; C5-PFK) mixtures have remarkable potential to replace

  • Why Gas Prices Are Rising So High - Reasons for Fluctuations

    For instance, between 2010 and 2014, oil prices never fell below $70 per barrel and frequently spiked above $100. The price of gas was also consistently high during this period, staying between $3 and $4 per gallon. In mid-2014, when the price of crude oil plummeted to less than $50 per barrel, gas prices tumbled to less than $2 per gallon.
