Advantages of Liming sulfur hexafluoride insulation
Published on:2017-01-07 Click:208What are the advantages of Liming sulfur hexafluoride insulation? Philippe, a sulfur hexafluoride manufacturer, talks to you.
SF6 appeared in 1900, and began to be used as insulation and arc extinguishing medium in the 1950s. In 1965, sulfur hexafluoride metal enclosed switchgear (GIS) began to appear. All equipment other than transformers were enclosed in gas insulated substations with grounded metal enclosures. 0.3-0.4 Liming sulfur hexafluoride was filled in the enclosures as insulation between phases and between phases.
Small size. At 0.1MPa, the insulation strength of SF6 is about 3 times that of air, and all high-voltage conductors are enclosed in metal enclosures. In addition, Liming sulfur hexafluoride has high reliability and long service life. It shall not be affected by adverse environmental factors, such as typhoon, saline alkali, earthquake and other disasters. No fire hazard, no environmental pollution, and friendly to residents.
In high cold area, the liquefaction of sulfur hexafluoride gas in GIS circuit breaker must be considered. Generally, the liquefaction problem is solved by heating short circuit or using SF6-N2 mixed gas as arc extinguishing medium. Hotline: 139-4929-0069.
