变电站二次设备舱是电力系统中的关键组成部分,负责安装和管理各类控制、保护、监测及通信设备。这就意味着二次设备舱需要有很强的适应性,以满足当地的环境要求。由于台风影响,吉林永吉变电站二次设备舱存在防水问题。因此,对其进行了改进。在原有结构的基础上,在内外层板中加入聚氨酯保温板,提高预制舱的吸水性。并对改进后的二次设备舱进行了环境适应性研究。主要对二次设备舱在极限温度下的工况进行了分析,使其具有实用性。The secondary equipment compartment of a substation is a key component of the power system, responsible for installing and managing various control, protection, monitoring, and communication equipment. This means that the secondary equipment compartment needs to have strong adaptability to meet local environmental requirements. Due to the impact of the typhoon, there are waterproofing issues in the secondary equipment compartment of Jilin Yongji Substation. Therefore, it has been improved. On the basis of the original structure, polyurethane insulation boards are added to the inner and outer layers to improve the water absorption of the prefabricated cabin. And environmental adaptability research was conducted on the improved secondary equipment cabin. The analysis mainly focuses on the working conditions of the secondary equipment compartment under extreme temperature, making it practical.
