摘　　要：SF6气体作为一种优良的绝缘和灭弧介质,广泛应用于电力设备中。就温室效应而言,SF6所带来的危害可以远超CO22500多倍。而且最主要的是这种气体有着极其稳定的性能,就现阶段的技术而言,很难对其进行降解,而且一旦这种气体混入到大气中,也是没有有效的办法对其进行回收。鉴于此,为了防止进一步加剧温室效应,对于该气体的使用应当尽可能的减少,甚至是不使用。就现阶段而言,不仅是我们国家,在全球范围内,大多数国家都是在发展循环经济。所以,环保型气体绝缘开关柜是未来中压领域发展的必然。As an excellent insulating and arc extinguishing medium,SF6 gas is widely used in power equipment.As far as the greenhouse effect is concerned,the harm caused by SF6 can far exceed CO22500.And the most important thing is that this gas has extremely stable performance.As far as the current technology is concerned,it is diffi cult to degrade it,and once this gas is mixed into the atmosphere,there is no effective way to recover it.In view of this,in order to prevent further aggravation of the greenhouse effect,the use of the gas should be reduced as much as possible,or even not used.At this stage,not only our country,but also on a global scale,most countries are developing a circular economy.Therefore,environmentally friendly gas insulated switchgear is the inevitable development of the medium voltage fi eld in the future.
