水内冷发电机冷却水系统水内冷发电机冷却水系统cooling water system for water-cooled generator水质。由于转子励磁电压低，泄漏电流小，而且转子空心钥线通水截面也较大，迄今未发现结垢影响转子温升的现象，故对转子水质的要求可低一些，即电导率不大于3拌S/cm(2o℃)。主要设备与流程为:水箱~冷却水泵~冷却器~滤网~转子绕组~水箱。水箱设有浮球阀，控制水位并自动补水，水位过高时，水由滋水管滋出。shulne一leng fadlonjl IengqueshU，xltong水内冷发电机冷却水系统(eooling watersystem for water一eooled generator)向水内冷发电机不间断地供应水温和水质符合标准的冷却水并具有自动监控功能的所有设备和装置的组合。由于对定、转子绕组冷却水质的要求有所不同，系统结构也不同(见透平发电机冷却方式)，冷却水可分开成定子和转子两个独立的闭式循环系统，但欧洲国家水水里冷却的发电机多合并为一个系统。水内冷定子水系统为防止大型高电压定子空心导线结垢堵塞，必须控制铜的氧化与沉淀。首先要把定子水箱密封起来，并加压充氮或氢，以减少水中溶氧和CO:，同时增设旁路式离子交换器维持水的低导电率，以降低泄漏电流，从而减缓Cuo的沉淀。大型氢冷发电机的定子冷却水系统常布置成为整体的组合装t(如图所示)。冷却水泵将冷却水经冷却器压送到定子绕组的空心导线，出水流回水箱。系统的主要特点是:①密封式水箱充有低压氢气，由氢气系统经过减压调节阀供应。②供水管旁路上设有离子交换器。进人定子绕组的水质指标在中国一般规定为:电导率不大于2拌S/em(20℃)，pH值为7~8，硬度小于5拜mol/I』(200 MW以下)及小于1拜mol/L(200 MW及以上)，而其他国家只规定一个较严格的电导率指标，如小于0.5~LS拜S/cm。补充水可用凝结水或除盐水。③为提高运行自动化水平及可靠性，装有多路差压开关，进水自动恒温控制及监测仪表等，以控制监测进出水温、水电导率、绕组水压降及流量、水氢压差、水箱氢压、水箱液位、水泵出口和定子进口水压等运行参数，它们的电信号都输人监测控制柜，并参与机组的自动化监控。④安全措施有温度保护和断水保护，前者有恒温器调节冷却器的冷却水量，使定子进水温度维持在允许值(一般为30一50℃)范围内，如出水温度超出85℃时就报警;后者则在“流量非常低”与两台水泵“停车”同时报警时，若延时305仍无变化，发电机就自动解列并灭磁。总进水管发电机大气润节肠不┌─┐│ │└─┘ 定子绕组冷却水系统简图水内冷转子水系统中国水内冷转子绕组的出水限于现有结构状况，无法与空气隔离，因此在运行中受到溶氧、COZ及Ca离子的作用，水质逐步恶化。一般可定期换水或连续排放并补充，或添加缓蚀剂以改善
