12、 46th35kV开关柜除湿改造方案一、工程项目名称35kV开关柜除湿方案二、项目来源解决变电站35KV开关柜内部潮湿局部放电等问题。三、现场堪察情况及解决方案（一）勘察情况勘察范围：变电站35kV开关柜（二）现场情况与分析 现场照片：35kV开关柜母线室湿度72%据现场情况, 母线桥架内部湿气聚集并导致局部放电原因分析如下： （1）该变电站为相对封闭式设计，由于电缆地沟与开关柜相通，产生烟囱效应，环境温差过大时，极易使潮湿空气汇集于开关柜内，极易使湿热空气汇集于开关柜内部，导致开关柜母线室潮气较为严重，长期以来容易引起开关柜母线室潮湿空气聚集，导致母线与外部壳体绝缘距离减小，从而产生局部放电

13、现象，对变电站的运行存在安全隐患。（2）在环境湿度较大时，开关柜母线室潮湿现象更为严重，对变电站的运行存在安全隐患。针对室内开关柜内部湿度过高，并存在潮湿空气聚集现象，我公司针对此类问题进行了系统的技术分析，需要构建有效的环境监测与智能控制系统。HK-SEPRI-T型顶置式除湿装置是针对开关柜运行温湿度环境改善并预防凝露现象而专门研制的高新技术产品。本装置采用微处理器控制技术，独立式自控顶置式除湿装置，不仅能同时对环境温湿度进行监测，并通过LED数码显示，还可通过按键对温、湿度分别进行相应的设置并显示。凝露水份采用雾化技术强制蒸发，安全排出。本装置是保障智能电网高效、安全运行的首选除湿设备。装

14、置功能：1)对环境温、湿度进行实时温湿度监测。2)对开关柜顶部加装为其独立设计、制造的大功率专用顶置式除湿装置。3)故障告警输出接口。4)凝结水分采用雾化技术，自动雾化隔离排出，无需敷设排水管路。（三）用户要求1）解决开关柜内部空气潮湿问题，提高安全可靠性。 2）顶置式除湿装置为独立一体化控制设计。（四）解决方案经实际的现场勘查及变电站的工作人员的反映，我公司拟定了以下解决方案。通过加装HK-SEPRI-T型顶置式除湿装置以解决 开关柜 的凝露问题。新型的顶置式除湿装置可有效的降低柜内空气中的水份含量，环境温度变化时，不易产生凝露现象，从根本上解决电气柜凝露现象。凝露水采用雾化隔离排出。产品简

15、介 HK-SEPRI-T型顶置式除湿装置用于电力设备如母线桥架、高低压控制柜、高低压开关柜、环网柜、仪表箱等需要除潮湿、防凝露的场合。该装置采用微处理器控制技术，针对于母线桥架、开关柜设备内部空间紧凑、环境湿度高、安全距离等因素而研制的产品。大功率快速除湿，凝露水份采用雾化隔离排出。并采用一体化集成设计，体积小、安装方便、维护简单。该装置由智能控制单元、强制循环单元、除湿单元、雾化单元、自检单元、故障告警单元组成。图1 顶置式除湿装置示意图工作原理母线桥架或开关柜内部潮湿空气经进风口吸入后，先经环境传感器对吸入的空气进行检测，湿度超标，再经特殊风道流动，进入除湿单元处理，把空气中的水份凝露成水

16、珠并且与设备完全隔离后排出，排出的水经雾化单元强制挥发，然后对处理后的空气加热升温，通过风扇把干热空气经出风口吹入桥架内部。经过除湿单元对母线桥架或开关柜内部空气强制循环，使电气设备内的空气相对环境改善，完成整个除湿过程。当母线桥架或开关柜内部湿度在启动值以下时，每30分钟风扇启动3分钟，循环空气，使采样值更准确，实时监控母线桥架或开关柜内部湿度变化。若湿度变化可及时启动热交换单元工作，避免事故发生。雾化单元采用超声波高频震荡，将水雾化为15微米的超微粒子，通过隔离风动装置将水雾挥发。湿度除湿（制冷 凝露）故障存在超标故障存在环境监测排水风量监测告警输出水位监测雾化挥发除湿装置工作原理图如图2
