In order to be suitable to different rotation directions of magnetic field under the conditions of power generation and water pumping of units,the Baoquan Pumped Storage Power Station installs the phase change knife switch,the driven knife switch,the driving knife switch,the starting-up busbar and specific equipment.
宝泉抽水蓄能电站为适应机组在发电和抽水工况的不同磁场旋转方向,设置了换相闸刀、被拖动闸刀、拖动闸刀、起动母线及特殊设备,并针对各种特殊工况下的非常运行方式,设置了电压相序监视保护、低频保护、低功率保护、逆功率保护、低频过流保护及定子保护。
When the knife switch overloaded,temperatures of switch leads,the meet place of dynamic and static slices,and the fuse will rise,which might light surrounding burnable materials and causing fire.
通过实验研究了不同类型的闸刀开关在不同过负荷电流条件下的温度上升情况,测量了闸刀开关在两类过负荷条件下的最高温度以及达到最高温度需要的时间,并对影响闸刀开关温度升高的因素以及达到最高温度时能否引燃周围可燃物进行了分析讨论。
