Study on the method of outdoor ring network cabinet based on finite element method
基于有限元法的户外环网柜防凝露方法研究

摘要

电力设备的防潮，有助于提高电力设备的可靠性，传统的防潮措施是通过添加风机、除湿机等设备、虽然能有效地防潮，但是需要定期对设备进行维护、加大维修人员的工作量。本文对环网柜容易产生凝露的原因进行了分析，分析了外界条件对环网柜内部温湿度的影响效果，概括出两个重要的原因，并提出了相应的改进措施，采用有限元分析软件ANSYS 对改进土建基础的环网柜的温度场和湿度场进行仿真计算，仿真结果验证改进基础后的理论可行性，最后，采用设计的新土建基础对某线路进行改造，通过定期监测温湿度的变化验证了本设计的有效性。

Abstract

The moisture-proof of power equipment, help to improve the reliability of power equipment, the traditional moisture-proof measures are by adding the fan, dehumidifier and other equipment, although can effectively moisture-proof, but need to maintain the equipment regularly, increase the workload of maintenance personnel. This paper analyzes the causes of the ring network enclosure, analyzes the influence results of the external conditions, summarizes the two important results, and makes the changes of the temperature and humidity monitoring regularly.
