基于声震一体的变电站监测装置设计

Design of transformer substation monitoring device based on acoustic seismic integration

在役变电站一次、二次设备出现问题的频率较高,当设备发生故障或者所处环境发生改变时,其所发出的声音和震动信号也会随之改变,因此对设备声音和震动参量的快速辨识可以协助开展站内设备安全管理。为此设计了一种用于电力物联网的声震一体状态监测装置,该装置能够实时采集变电站内环境和设备运行过程中的声音和震动数据,并对数据进行融合处理,实现对环境和设备运行状态的长期监控,为克服传统单一参量监测诊断易造成漏判与误判的问题提供了解决思路,有助于提高无人值守变电站的安全工作水平。

The frequency of problems with the primary and secondary equipment of the in-service substation is relatively high. When the equipment fails or the external environment changes, the sound and vibration signals it emits will also change accordingly. Quick identification can assist in the safety management of equipment in the station.To this end, an integrated acoustic and vibration state monitoring device for the power Internet of Things is designed. The device can collect real-time sound and vibration data in the substation environment and during equipment operation, and fuse the data to realize the environment and the environment. The long-term monitoring of equipment operating status provides a solution for overcoming missed judgments and misjudgments easily caused by traditional single-parameter monitoring and diagnosis, and helps to improve the safe working level of unattended substations.
