浅析SF_6回收再生气体在广东电网的应用

Application of recuperated sulphur hexafluoride gas in Guangdong power grid

随着近年SF6电气设备在广东电网系统的广泛应用,投运多年的SF6气体因水分增大,杂质增多,灭弧性能下降,需要大量更换,否则会严重影响电气设备的安全运行,这样,大量更换下来的SF6气体的处置问题便需亟待解决。SF6气体回收再生工作,一方面可遏止SF6气体直接排放,保护环境,保障健康;另一方面可变废为宝,节约电网运行维护成本,是电网系统循环经济的一大亮点,社会效益和经济效益明显。

Sulphur hexafluoride （SF6） electrical equipments are widely used in the power system of Guangdong, China. A large quantity of SF6 gas that has been in operation for many years has to be replaced due to the increased moisture and impurities as well as the lowered arc-extinguishing performance; otherwise the safe running of electrical equipments will be seriously impacted. So the disposal of the replaced SF6 gas has become a problem pressing for solution. The recovery and regeneration of SF6 gas can restrain the direct emission of SF6 gas, protect environment and safeguard health on the one hand; on the other hand it can change wastes into valuables and save operation and maintenance costs of power network, thus becoming one of the bright spots in the cyclic economy of power system and bringing about remarkable socio-economic benefits,
