550kV罐式断路器在寒冷地区的保温方法

The Method for 550kV Tank Circuit Breaker to Keep Warm in the Cold Area

随着SF6产品越来越多在低温地区使用,SF6断路器在低温地区使用时存在气体液化现象,不可忽视。作为制造厂家,为了保证产品的安全运行,必须采取应对措施来解决。在断路器外壳上加装保温装置,当环境温度低于SF6气体液化温度时,加热装置投入使用,对断路器内SF6气体进行加热,保证断路器的各项性能。

As more and more SF6 products used in the low-temperature area, the SF6 gas liquefaction phenomenon of CB may not be ignored. As the manufacturer, to assure the safe operation of the products, certain measures should be taken. Equipped with the keeping-warm device on the enclosure of CB when the ambient temperature below the SF6 gas liquefaction temperature, heating device will be used for heating SF6 gas in the CB, which will make sure the performances of CB.
