严寒地区变电站防冻害措施研究

Research on Anti-freeze Measures of Substations in Cold Regions

通过对严寒地区多个变电站气候特点、地质条件的总结,针对变电站建筑物墙体开裂、道路隆起,基础上拔设备倾斜,积水等冻害现象,介绍了冻害等对变电站安全运行的危害性,指出了防冻措施的重要性,分析了产生冻胀破坏机理及原因,结合建筑材料的选择、施工组织技术的要求,最终提出了防冻害处理措施及建议。

The climatic feature and geologic conditions of several substations which located in cold regions will be summarized in this contribution. In view of the damage of cracks in building wall, buckling of roadways, incline of equipments due to uplift load on foundations, and water logging, etc., frozen damage to the safety operation of substations will be introduced, and the significance of anti-freezing measures will be indicated. Combined with the choice of building material, the requirement of construction technology and organization, measures and suggestions on anti-freeze process will be raised finally.
