Hydran M2-X GE 变压器的增强型 DGA监控
变压器是电网中关键且昂贵的部件,了解它们的健康状况对于拥有一个可靠的电网至关重要。当变压器的绝缘系统受到过度压力时,就会产生溶解在油中的气体。油中溶解气分析(DGA)被认为是断层发育的最佳指标。
Hydran""M2是一种连续在线油中溶解气体和水分监测装置,可在变压器发生故障时向工作人员发出警报。它提供关键的监控信息,并将计划外中断的风险降至最低。
通过连接额外的传感器(例如]顶部和底部油箱油温,变压器负载或环境温度),可以捕获额外的信息,并用于与DGA和湿度值相关联,以便更深入地分析变压器的状况。
这些丰富的数据不仅可以使用M2广泛的通信选项进行原始传输,还可以通过基于IEEER标准的变压器数学模型的板载计算转换为有用的信息,以提供进—步的条件信息。关键好处
·持续测量溶解的故障气体和油中的水分,以便在变压器发生重大故障之前及早发现潜在问题·使用额外的传感器(用于负载,油温)和基于IEEE标准的内置变压器模型计算扩展监控功能·广泛的通信选项和协议(包括IECR61850)简化集成到SCADA或DCS系统
·经过验证的第三代设计,具有非常大的全球安装基础
·支持新的低可燃性酯基油以及矿物变压器绝缘油
Transformers are critical and expensive components of the power grid, and knowing their health is critical to having a reliable grid. When the insulating system of the transformer is subjected to excessive pressure, gas dissolved in the oil is produced. Dissolved gas analysis in oil (DGA) is considered to be the best indicator of fault development.
Hydran""M2 is a continuous in-line dissolved gas and moisture monitoring device in oil that alerts workers in the event of transformer failure. It provides critical monitoring information and minimizes the risk of unplanned outages.
By connecting additional sensors (e.g., top and bottom tank oil temperature, transformer load or ambient temperature), additional information can be captured and used to correlate DGA and humidity values for a deeper analysis of the transformer's condition.
This rich data can not only be transmitted raw using M2's wide range of communication options, but can also be converted into useful information by on-board calculations based on the IEEER standard's mathematical model of the transformer to provide step-by-step conditional information. Key benefits
· Continuous measurement of moisture in dissolved fault gases and oils for early detection of potential problems before a major transformer failure · Use of additional sensors (for loads, Oil temperature) and a built-in transformer model based on IEEE standards to compute extended monitoring capabilities. A wide range of communication options and protocols, including IECR61850, simplify integration into SCADA or DCS systems
Proven third generation design with a very large global installed base
· Support new low inflammable ester base oils and mineral transformer insulating oils
