摘要
根据变电站中对接触电势校核的需要,对变电站内敷设的操作绝缘地坪的各种材质的绝缘性能进行了研究。结合试验结果和理论分析提出变电站内最适合采用的操作绝缘地坪的材质和厚度。研究结果表明,变电站内常规材质操作绝缘地坪的绝缘性能不都能满足变电站的安全运行的需要,建议采用复合材料的操作绝缘地坪。
According to the demand of checking contact potential in substation,the material insulating properties of operating insulation ground floor are studied in this paper.The most suitable material and thickness of operating insulation ground floor is proposed by test and theoretical analysis.In addition,it is shown that not all the materials commonly used in substation meet the needs of safe operation in substations.
