半路堤泵站是湖北省大型泵站之一,装有3台 DTL-325/56-40,2800千瓦大型同步电机,并配装 CJ-2.8米轴流泵。从1979年7月投产以来,为荆州四湖地区的抗旱排涝发挥了很大作用。但在1987年2月的预防性耐压试验中,发现3号机的定子绕组B 相有闪络形放电现象。经查明验证,B 相第5组第1个线棒下的背面,定子槽口处被
Half embankment pumping station is one of the major pumping stations in Hubei Province, equipped with three DTL-325 / 56-40,2800 kilowatts large synchronous motor, and equipped with CJ-2.8 meters axial flow pump. Since it was put into operation in July 1979, it has played a significant role in drought and waterlogging in the Four Lakes of Jingzhou. However, in February 1987 preventive pressure test found that No. 3 of the stator winding phase B flashover discharge phenomenon. After verification, the back of the first bar under the 5th phase of the B phase is located at the notch of the stator
