Data acquisition and processing system of oil-immersed transformers based on the embedded Linux

当前状态监测技术有监测参数不全、实时性不高等缺点,本文设计了一款基于嵌入式Linux的油浸式变压器状态监测数据采集系统,利用该平台实现对智能变压器中轻重瓦斯含量、油温等模拟量和轻重瓦斯状态、冷却器状态等开关量信息的实时在线监测,监测参数较全、实时性较高,经实际检验,本系统能够良好的评估变压器的运行状况,提高了油浸式变压器的在线监测水平。

Current status monitoring technology has many defects,just like not all monitoring parameters and not real-time and so on.This paper introduces a data acquisition and processing system of oil-immersed transformers based on the embedded Linux.Using this platform it can realize the on-line monitoring of the analog of gas content and oil temperature,and also the switch quantity of gas status information and cooler condition.It can monitor more parameters and it can realize real-time function.Through the actual inspection,this system evaluates the status of the intelligent transformers well and improves the level of the online monitoring of the power transformers.
