concordegas SF6 decomposition leak pointer for gas-insulated switchgears

Sep 20, 2011 · Fig. 11-2 Conversion of water vapour content into dewpoint for SF6 gas at atmospheric pressure. Arcing causes the decomposition of very small amounts of SF6 gas. The decomposition products react with water, therefore the gas's moisture content, particularly in the circuit-breaker, is controlled by drying (molecular) filters.

  • SF6 Decomposition in Gas-Insulated Equipment - IEEE Journals

    Abstract: The increasing application of SF6 as an insulating gas has led to many studies on SF6 decomposition in gas-insulated equipment. In the presence-of an electric arc, spark or corona, SF6 decomposes to a wide variety of chemically active products which possess completely different properties from SF6.

  • Introduction to Gas Insulated Substations / Switchgears (GIS)

    Gas insulated switchgear parts. As the dielectric strength of SF6 gas is higher than air, the clearances required are smaller. Hence the overall size of each equipment and the complete sub-station is reduced. The various modules are factory assembled and are filled with SF6 gas. Thereafter, they are taken to site for final assembly.

  • Effect of Moisture inside SF6 Gas Insulated Switchgear

    Nov 17, 2011 · When switching is done in a SF6 Gas insulated switchgear, arching will occur. This is because there is a high impedance on the breaker switch when the switch is opened and high voltage current tries to flow through the impedance. The arching release immense heat and SF6 gasses will quench the arching in order to prevent it from spreading.

  • The SF6 Decomposition Mechanism: Background and Significance

    Jan 24, 2017 · Gas Insulated Switchgear (GIS) has been widely used in substations. The insulating medium used in GIS is sulfur hexafluoride (SF6) gas. However, the internal insulation defect existed in GIS would inevitably lead to partial discharge (PD), and cause the composition of SF6 to SOF2, SO2F2 and SO2 and other characteristic component gases. The decomposition phenomenon would greatly reduce the

  • Gas-Insulated Transmission Line (GIL) System Design

    Introduction to GilTechnical DataHigh em CompatibilityGIL systems are based on the successful SF6 tubular conductor technology, which has been around for several decades. GIL consist of a central aluminum conductor with a typical electrical cross section of up to 5,300 mm2. The conductor rests on cast resin insulators, which center it within the outer enclosure. This enclosure is formed by a sturdy aluminum tube, which provides a solid mechanical and electrotechnical containment for the system. To meet up-to-date environmental and technical aspects, GIL are filled with an insulating gas mixture of mainly nitrogen and a smaller percentage of SF6 gas. This concept also has logistic advantages.All elements such as tubes, angles and special modules are lightweight and small enough to be transported by comparatively light standard trucks.
