预制舱变电站多状态监测技术探讨

预制舱变电站集中接入已逐步成为城市配电系统的发展趋势。综合预制舱变电站内SF₆气体浓度、温/湿度、噪音、污秽等因素，构建了综合状态监测系统，并基于预制舱配置风机提出了强制风机策略，以调节舱内环境，减少变电站运维。所提方法考虑了多环境因素的综合影响，解决了当前预制舱式变电站中风机启停混乱的问题，提高了预制舱变电站环境控制的可靠性与灵敏性。

Discussion on Multi-Status Monitoring Technology of Prefabricated Substation

Centralized access of prefabricated cabin substation has gradually become the development trend of urban power distribution system. Based on the SF₆ gas concentration, temperature and humidity, noise, pollution and other factors in the prefabricated cabin substation, an integrated status monitoring system is built, and a forced fan strategy is proposed based on the fan configuration in the prefabricated cabin to adjust the cabin environment and reduce the operation and maintenance of the substation. The proposed method takes into account the comprehensive influence of multiple environmental factors, solves the problem of fan start and stop confusion in prefabricated cabin substations, and improves the reliability and sensitivity of environmental control in prefabricated cabin substations.
