摘要:
目前对电网断路器中的SF6气体湿度检测大都是现场检测,不能够实时监控; 在检测方法上普遍采用的是光电检测法,其无法识别镜面上的凝聚相是露点还是霜点,导致测量误差大。研制的基于无线传输和图像控制技术SF6湿度检测仪可以识别露霜,根据结露统计数量调节镜面制冷速度,使镜面温度准确地平衡于气体露点温度,提高了检测精度; 并通过无线传输方式将结果送至检测中心,实现了实时检测和数据收集整合。采用了适应用于图像识别处理的高速DSP对镜面图像进行实时采集和处理,并辅助以微控制器对温度进行控制和测量,数据传输由GSM模块完成; 图像识别软件采用了灰度共生矩阵法实现了对露点数量的统计,实现了对气体露点温度更精准的测量。
Abstract:
SF6 gas humidity detection in the Power Circuit Breakerare mostly on-site inspection, so it can not be real-time monitoring. The method of photoelectric detection is adopted generally in the dew-point hygrometer atpresent,but this dew-point hygrometer cannont distinguish whether condensationphotograph on the mirror is dew point or frost point,so measure errors are incurred. This system can distinguish the dew point from frost point, and can adjustrefrigeration rate by considering the number of dew-point,making the temperatureof mirror balance in the dew point temperature,so it can improve accuracy. Theresult will be sent to the testing center by wireless transmission, and this achieves real-time detection and data collection.The high-speed DSP which is used for identifying and processing image to acquire and process the mirror image,andthe microcontroller is used to control and measure the temperature of the mirror.GSM is used to translate data. The method of Gray Level Co-occurrence Matrix isused to count the number of dew-point,and this lead to higher accuracy.
