溧阳抽水蓄能电站进水球阀系统故障分析与处理郜斌,王超,于中舒,周炀(江苏国信溧阳抽水蓄能发电有限公司,江苏溧阳213300)摘要:溧阳抽水蓄能电站进水球阀每台机组设置一台,因为机组启停频繁,球阀开关动作频率较高,所以在长期运行过程中由于设备损坏、老化等原因,球阀系统电气和机械设备出现异常情况,造成球阀开启和关闭失败等问题。结合电站球阀实际情况分析并提出合理的处理方法,及时处理设备缺陷,从而使电站球阀动作成功率大大提升。关键词:溧阳抽水蓄能电站;进水球阀;处理方法;成功率中图分类号:TM07DOI:10.19768/j.cnki.dgjs.2023.04.005FaultAnalysisandTreatmentofInletBallValveSysteminLiyangPumpedStoragePowerStationGAOBin,WANGChao,YUZhongshu,ZHOUYang(JiangsuGuoxinLiyangPumpedStoragePowerGenerationCo.,Ltd.,Liyang213300,China)Abstract:EachunitofLiyangpumpedstoragepowerstationisequippedwithawaterinletballvalve.Theunitstartsandstopsfrequently,andtheballvalveswitchingfrequencyishigh.Duetoequipmentdamage,agingandotherreasonsduringlong-termoperation,theelectricalandmechanicalequipmentoftheballvalvesystemhaveabnormalconditions,resultinginthefailureofballvalveopeningandclosing.Combinedwiththeactualsituationoftheballvalveofthepowerstation,areasonabletreatmentmethodisdevelopedtodealwithequipmentdefectsintime,sothatthesuccessrateoftheballvalveoperati...
