中文摘要：

为降低开关柜的事故发生率，设计了开关柜触头温度测控系统。首先利用层次分析法得出开关柜散热最佳方案，即在开关柜后面板上加装翅片热板隔离式热交换器；然后基于翅片散热和ZigBee，设计了开关柜触头在线温度测控系统，该系统包含数据采集与温度控制层、数据传输层和站控层。测试结果表明，翅片散热器散热效果良好．所设计的开关柜触头在线温度测控系统可实现设备状态数据的可靠快速传输和监测预警信息的可视化。

英文摘要：

In order to reduce the fault rate of switch cabinet,an online contact temperature monitoring and control system is designed. AHP（Analytic Hierarchy Process） is applied to get the best heat dissipation scheme of switch cabinet,i.e, a finned radiator installed on the rear panel of switch cabinet,and an online contact temperature monitoring and control system based on finned radiator and ZigBee is designed ,including the data acquisition and temperature control layer,the data transmission layer and the station control layer. Testing results show that ,the heat dissipation effect of finned radiator is excellent and the designed system realizes the fast and reliable transfer of equipment status data and the visual display of monitoring and alarm information.
