高压开关柜在线温度监测系统的研究
|
摘要
高压开关柜是电力系统重要的控制设备,对电力系统的安全和可靠运行起着举足轻重的作用。高压开关柜长期工作在高电压、大电流、强磁场的环境中,而且大都采用封闭结构,散热条件较差,温度容易升高,造成设备故障。为保证开关柜的正常运行,提高电力系统工作的可靠性,需要随时了解开关柜温度变化情况。由于传统的高压开关柜的温度监测方法落后,功能简单,不能满足对柜内温度的实时、在线、无人监控,所以急需一个能够实时、在线、无人化的高压开关柜温度监测系统。
文章对高压开关柜在线温度监测系统的功能进行了分析,提出了系统的总体设计方案,并将其分为温度数据采集系统、通信系统、后台软件系统三个部分分别进行研究。
文章首先对温度数据采集装置的硬件设计进行了详细的介绍;然后在Keilc软件平台上对温度数据采集装置的软件进行了设计,实现了高压母线温度的测量、柜内空气温度的测量、红外数据传输、LCD数据显示、键盘输入、以太网通信等功能;最后介绍了后台软件系统的设计,基于VC++编程环境,采用面向对象技术,实现了温度数据的接收、显示、报警、存储和读取等功能。整个系统的各功能模块的整合、试验调试工作均已完成,并且对系统的功能扩展和完善提出了改进意见。
The high voltage switch cabinet is one kind of important controlling devices in power utilities, which plays an important role in keeping the electric system safe and secure. The high voltage switch cabinets are always running under the high voltage, large current and strong magnetic field environment. And most high voltage switch cabinets adopted the enclosed construction which will lead to many problems, such as dissipating heat slowly. These environments seriously endanger the high voltage switch cabinets and may even damage them. So, in order to keep the safety of the high voltage switch cabinets and improve the electric power system security, we need to know the real time temperature changes of the high voltage switch cabinets to take previous actions. But the traditional method of temperature measurement is falling behind because that the function is single and can't meet the need of real-time and unattended monitoring of the high voltage switch cabinet's temperature. So, the electric power companies are crying out a real-time and unattended monitor for the high voltage switch cabinet.
In this paper, we researched on the function of the real-time monitor for high tension switch cabinet and brought forward the genial design, which was devided into three part: temperature data acquisition system, communication system and background software to research separately.
We first introduced the hardware design of the real-time monitor for high tension switch cabinet detailly; then we designed the software of this device based on Keil c software platform. The design of the real-time monitor for high tension switch cabinet realized the functions as follows: the high voltage bus temperature testing, the air temperature testing of the cabinets, infrared data transmission, LCD display, keyboard entry, ethernet and so on. At last, the background software design was introduced. It was base on C++ programming environment and Object Oriental Technique, which realized the functions as follows: data transmission and display, alarm, storage task and so on. In the end, we finished debugging the whole system and carried out the technological forecasting for this system.
