摘要: 针对户外开关柜高压触点温度测量易受环境影响、精度较低等问题,设计了10 kV户外开关柜高压触点无线温度测量系统.该系统以无线射频单片机CC2530F256为核心部件,利用ZigBee网络的自组织性,将温度测量终端节点与手持式协调器节点组网,实现户外开关柜高压触点温度的精确测量和数据的无线传输.实验结果表明,该系统受环境影响较小,且测得的温度数据误差小于1℃,可满足户外开关柜高压触点在线监测的要求.Abstract: Aiming at the problems of outdoor switchgear high-voltage contact temperature measurement such as vulnerability to environmental impact and low precision, the 10 kV outdoor switchgear high-voltage contact wireless temperature monitoring system was designed.The system selected the wireless RF MCU CC2530F256 as the core chip, using the self organizing of ZigBee network, through temperature measurement terminal node and handheld coordinator node of the network, realized the outdoor switchgear high-voltage contact temperature data precision measurement and wireless transmission.Experimental results showed that the system was not easy to be affected by the environment, and the measured data error was less than 1℃.It could satisfy the requirement of outdoor switchgear high-voltage contact temperature online monitoring.
