变电站风吹雪灾害的研究与防治
|
摘要
风吹雪(又称风雪流,风积雪)是以气流为动力,雪粒子在大气中杂乱运动的天气现象,它是一种非典型的固气两相流体运动,多发生在高海拔、高纬度、地形复杂的区域。风吹雪严重威胁着变电站的安全运行。通过对风吹雪的分布、形成机理、堆积转化机制、风雪流场结构及规律的研究,从工程选址、变电站设计和因地制宜地采用"导"、"阻"、"改"、"除"等技术措施治理危害,以减少风吹雪对变电站的危害,保证变电站的安全运行。
The snowdrift(also known as snow flow, wind blowing snow) is based on air power, snow particles in the atmosphere and disorderly movement of weather phenomena, it is a kind of typical gas-solid two phase fluid motion, tend to occur in the area of high altitude, high latitudes, the complex terrain.Based on the snowdrift distribution, formation mechanism, accumulation mechanism, research on structure and regularity of snowdrift, from the site selection substation design and adjust measures to local conditions to adopt "guide", "resistance", "reform", "remove" technical measures, in order to reduce the snowdrift to the harm of substation, guarantee the safe running of the substation.
