消除瓦斯信号误发

Eliminate the Mistaken Gas Signals of Transformer

分析了电网调度自动化改造过程中,电磁型保护信号与RTU接口后,主变瓦斯保护信号误动误发的原因,并提出了改进方案,纠正了错误动作,使保护动作信号上传可靠,节省检修费用,提高单位经济效益。

The paper analyses the reason of the mistaken signal and action of the main transformer gas protection, which occurs when the electromagnetism protection signal joins to the RTU, during the process of the reconstruction of network dispatching automation. It gives an improved plan and adjusts mistaken actions and so the signal transmission is reliable, maintenance cost is reduced and economic benefit is raised.
