摘要
在现代电力系统中,高压带电体温度监测已经成为电气设备安全运行所面临的实际问题。本文提出了以ZigBee无线传感器网络为核心,以以太网为骨干网,采用CC2430芯片为传感器控制核心的高压带电体温度测量方案。试验证明,系统能够实时监测高压带电体温度变化,工作稳定可靠、具有较高的实用性和市场价值。
In modern power system,the temperature monitoring of high-voltage live parts has become one of practical problems in the safe operation of electrical equipment.This paper proposes a high-voltage live parts temperature measurement that includes ZigBee wireless sensor networks as the core,Ethernet as the backbone and CC2430 chip as the sensor control core.ZigBee network of the system runs on 2.4GHz free frequency band.When tree topology is used to build system network,the maximum root depth is 5.The network can monitor the high-voltage live parts within 150m radius circular area in real time.The system network is scalable and can support up to 65,535 nodes.The system temperature monitoring range is-55℃～＋125℃ with 14 bits resolution.When the range of monitoring temperature is-10℃～＋85℃,accuracy can be achieved within ±0.5℃.Through the experiment,the real-time temperature monitoring system of high-voltage live parts not only is stable and reliable but also has high availability and market value.
