摘　　要：水电站的离相母线在使用多年后,用以保持密封状态的元器件出现老化现象,从而导致离相母线的密封效果逐渐下降,泄露出较多的气体。配套微正压装置不具备建立标准压力的条件,设备故障不断,除湿效果很不理想。本文通过对多种提高和保持离相封闭母线绝缘水平的方法优缺点的比较,得出目前市场上节能环保、维护简单和高效,能提高和保持离相封闭母线绝缘水平的最佳方案。After the enclosed bus bar of hydropower station has been used for many years,the components used to keep the sealed state are aging,which leads to the gradual decline of the sealing effect of the separated bus bar and more gas leakage.The matching micro positive pressure device can not establish normal pressure,the equipment is in continuous failure,and the dehumidification effect is not ideal.By comparing the advantages and disadvantages of various methods to improve and maintain the insulation level of isolated phase bus,this paper concludes the best scheme to improve and maintain the insulation level of isolated phase bus in the current market,which is energysaving,environmental protection,simple and efficient maintenance.
