HYDRAN M2變壓器油中故障氣體在線監(jiān)測系統(tǒng)
一般規(guī)格
基于已經(jīng)現(xiàn)場驗證的技術(shù)，新的Hydran M2增加 了基于IEEE?和IEC?標準的變壓器數(shù)學(xué)模型，從 而可以提供實時的變壓器概況信息。這樣就不僅 僅是只監(jiān)控溶解氣體和濕度，而是拓展到對變壓 器更多故障形式的監(jiān)控。
當一臺重要變壓器發(fā)生不可預(yù)知的故障的時候， 就會對電網(wǎng)的運行和經(jīng)濟性產(chǎn)生嚴重的影響。當 今，許多電網(wǎng)和工業(yè)用戶的油浸式變壓器都接近 了設(shè)計壽命的底線，并且表現(xiàn)出明顯的故障率升 高。對電力供應(yīng)的嚴格規(guī)定，投資和操作費用的 預(yù)算的減少，和專業(yè)技術(shù)人員的短缺都需要延長 這些變壓器的使用壽命。
描述
Hydran M2是經(jīng)濟的，它是功能強大的一體化變 壓器監(jiān)控裝置，它允許電網(wǎng)和其他用戶部署對眾 多變壓器的監(jiān)控，并且會從它先進的特性中得到 收益。
Hydran M2早期故障報警模型通過在線故障氣體 和濕度傳感器對變壓器和其他油浸式設(shè)備早期故 障進行監(jiān)控。附加的數(shù)字和模擬量輸入允許對變 壓器其他變量的監(jiān)控。新的變壓器模型拓展了Hydran M2的監(jiān)控能力和資產(chǎn)管理能力，這可以 對設(shè)備操作和維護人員提供更多的決策幫助。

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.
System characteristic
? Real-time faulty gas and humidity measurement system in oil
? Does not allow vacuum gas extraction membrane
? Separate valve installation, no additional pumps and moving parts required
? Intelligent electronic devices based on microprocessors ? System-wide self-testing and self-diagnosis

? 1 Communication expansion connector – Ethernet 10-100Base T card – Analog modem
? Isolated RS-232 serial interface in place
? Remote connection isolated RS-485 serial interface
? Support DNP3 protocol (serial interface or TCP/IP)
? Extended adjustable frequency data and event logging
? Adjustable level and trend-based alarm Settings for gas, humidity, analog input and transformer model calculations
? User-friendly client/server graphical user interface (GUI) that allows multi-client access over TCP/IP
