摘　　要：SF6高压电器设备因其占地小、性能好等多方面优势越来越多的使用在负荷高涨的大中型城市变电站。为解决我国北方城市高寒地区使用SF6高压电器设备气体液化导致性能降低问题,通过对热力学及热传递角度的计算,确定了采用加热方式解决SF6气体低温液化所需容量。该计算方法对产品工程设计中加热器的容量确定起到原理说明及数据支撑的作用。Because of its small occupation of land good performance and many other advantages SF6 high voltage electrical equipment is more and more used in large and medium-sized cities substation which load rising. To solve the problem of performance reduction by using SF6 gas liquenfaction in alpine region in northern area, thermodynamic and heat transfer angle calculation is used. Heating method is determined to used to solve problem of SF6 liquenfaction and capacity requirment. The calculating method in the product engineering design of heater capacity is determined to play principle instructions and data support.
