摘要：由于当前国内常用的强油循环变压器冷却设备的控制方法效果欠佳，本文提出一种基于物联网的变压器风冷控制系统及控制方法，该系统包括无线油温传感单元、无线负荷传感单元、风机状态传感单元及无线温湿度环境传感单元和风冷主控单元。所述风冷主控单元与各传感单元基于无线构建传感采集网，获取变压器负荷、变压器顶层油温、环境温度以及风机运行状态，综合诊断变压器当前运行状态，不断优化变压器风冷控制策略，大幅提升风冷系统运行效率及效果。
Abstract: Since the control method of the current domestically used strong oil circulating transformer cooling equipment is not good, this paper proposes a transformer air-cooling control system and control method based on the Internet of Things. The system includes a wireless oil temperature sensor unit and a wireless load sensor. Unit, fan status sensor unit, wireless temperature and humidity environment sensor unit and air-cooled main control unit. The air-cooled main control unit and each sensor unit construct a sensor acquisition network based on wireless, acquire transformer load, transformer top oil temperature, ambient temperature, and fan operating status, comprehensively diagnose the current operating status of the transformer, and continuously optimize the transformer air-cooling control strategy, which greatly improves the operating efficiency and effectiveness of the air-cooled system.
