HYDRAN M2变压器油中故障气体在线监测系统
一般规格
基于已经现场验证的技术，新的Hydran M2增加 了基于IEEE®和IEC®标准的变压器数学模型，从 而可以提供实时的变压器概况信息。这样就不仅 仅是只监控溶解气体和湿度，而是拓展到对变压 器更多故障形式的监控。
当一台重要变压器发生不可预知的故障的时候， 就会对电网的运行和经济性产生严重的影响。当 今，许多电网和工业用户的油浸式变压器都接近 了设计寿命的底线，并且表现出明显的故障率升 高。对电力供应的严格规定，投资和操作费用的 预算的减少，和专业技术人员的短缺都需要延长 这些变压器的使用寿命。
描述
Hydran M2是经济的，它是功能强大的一体化变 压器监控装置，它允许电网和其他用户部署对众 多变压器的监控，并且会从它先进的特性中得到 收益。
Hydran M2早期故障报警模型通过在线故障气体 和湿度传感器对变压器和其他油浸式设备早期故 障进行监控。附加的数字和模拟量输入允许对变 压器其他变量的监控。新的变压器模型拓展了Hydran M2的监控能力和资产管理能力，这可以 对设备操作和维护人员提供更多的决策帮助。

HYDRAN M2 on-line monitoring system for faulty gas in transformer oil
General specification
Based on field-proven technology, the new Hydran M2 adds a mathematical model of the transformer based on IEEE® and IEC® standards to provide real-time transformer overview information. This is not only to monitor dissolved gas and humidity, but also to expand the monitoring of more failure forms of the transformer.
When an important transformer has an unpredictable failure, it will have a serious impact on the operation and economy of the power grid. Today, many oil-immersed transformers for power grids and industrial users are approaching the bottom line of their design life and show a significant increase in failure rates. Strict regulations on power supply, reduced budgets for investment and operating costs, and a shortage of specialized technicians all require extending the service life of these transformers.
Description
The Hydran M2 is an economical, powerful, all-in-one transformer monitoring device that allows power grids and other users to deploy monitoring of multiple transformers and benefit from its advanced features.
The Hydran M2 Early Failure Alarm model monitors early failure of transformers and other oil-immersed equipment with in-line failure gas and humidity sensors. Additional digital and analog inputs allow monitoring of other transformer variables. The new transformer model expands the monitoring and asset management capabilities of the Hydran M2, which provides more decision-making assistance to equipment operators and maintenance personnel.
