摘　　要：绝缘子是电力系统中十分重要的一类电气设备,作为电网中种类繁多、用量庞大的一种零部件,其绝缘性能对整个输电系统的稳定运行起着非常关键的作用。文章中通过研究绝缘子放电辐射紫外线的原理,研制出基于STC89C52单片机、紫外线传感器R2868、温湿度传感器SHT11为核心的紫外线检测系统。通过进行仿真和实验,该系统可以有效检测到绝缘子放电辐射出的紫外线脉冲数量以及脉冲数与测试距离的关系,距离越近检测到的紫外脉冲数目越多。该项研究对电力系统绝缘子检修和保证电力系统安全稳定运行具有十分重要的意义。Insulator is a very important type of electrical equipment in the power system. As a kind of parts and components in the power grid,its insulation performance plays a very important role in the stable operation of the whole transmission system. In this paper,based on STC89C52 single chip microcomputer,ultraviolet sensor R2868,temperature and humidity sensor SHT11,the UV detection system is developed by studying the principle of ultrasonic radiation of insulator radiation. Through the simulation and experiment,the system can effectively detect the number of UV pulses emitted by the insulator and the relationship between the number of pulses and the test distance. The closer the number of UV pulses is,the more the number of UV pulses detected. The research of this paper is very important for the maintenance of power system insulators and the safe and stable operation of power system.
