摘要
为了缩短机场配电室变压器在线监测系统在实际应用中的响应时间,提高检出率和监测效果,本文基于光声光谱法设计了机场配电室变压器在线监测系统。在系统数据获取方面,利用光声光谱检测获取变压器的油气声波信号。在系统功能方面,利用气体的光声信号与气体浓度的线性关系,确定故障气体浓度。根据变压器运行状态判断原则,输出变压器状态的监测结果。经实验证明,本文设计系统响应时间较短,且检出率较高,说明本文设计的变压器在线监测系统具有良好的监测效果。
In order to shorten the response time of the transformer online monitoring system in the airport power distribution room in practical application and improve the detection rate and monitoring effect, this paper designs the airport power distribution room transformer online monitoring system based on photoacoustic spectroscopy. In the aspect of system data acquisition, photoacoustic spectrum detection is used to obtain the photoacoustic signal of transformer gas. In terms of system function, the linear relationship between photoacoustic signal and gas concentration is used to determine the fault gas concentration. According to the judgment principle of transformer operation status,output the monitoring results of transformer status. The experiment shows that the system designed in this paper has a short response time and a high detection rate, which shows that the transformer online monitoring system designed in this paper has a good monitoring effect.
