Description: 理工大学的一篇学士论文，个人感觉值得借鉴。用单片机作控制系统。干式变压器温度控制系统是维护干式变压器运行的重要部件，能有效防止变压器温升过高而引发事故，还能促进变电站的科学管理，通过降低温度实现变压器的经济运行，其工作可靠性的高低和操作是否方便将直接影响到干式变压器的运行质量。本设计从系统功能、硬件结构和程序设计等方面介绍了一种基于AT89C51单片机为核心、Pt100铂电阻为温度传感器并以NE555定时器作为A/D转换器，拥有看门狗电路、LED显示及简单的按键系统构成的干式变压器温度检测仪。-Polytechnic University, a Bachelor of papers, personal feel is worth learning from. With single-chip microcomputer for control systems. Dry-type transformers temperature control system is the maintenance of dry-type transformers to run the important parts, are effective in preventing excessive transformer temperature rise caused by the accident, but also to promote the scientific management of substation, the transformer by reducing the temperature to achieve the economic operation, reliability of its work the level of operating convenience and will directly affect the operation of dry-type transformer quality. The design features from the system, hardware design, structure and procedures introduced AT89C51 single-chip microcomputer-based at the core, Pt100 platinum resistance temperature sensor and timer NE555 as A/D converter with a watchdog circuit, LED display and simple push-button system consisting of dry-type transformers temperature detector.
