當(dāng)一臺(tái)重要變壓器發(fā)生不可預(yù)知的故障的時(shí)候, 就會(huì)對(duì)電網(wǎng)的運(yùn)行和經(jīng)濟(jì)性產(chǎn)生嚴(yán)重的影響。當(dāng) 今,許多電網(wǎng)和工業(yè)用戶(hù)的油浸式變壓器都接近 了設(shè)計(jì)壽命的底線,并且表現(xiàn)出明顯的故障率升 高。對(duì)電力供應(yīng)的嚴(yán)格規(guī)定,投資和操作費(fèi)用的 預(yù)算的減少,和專(zhuān)業(yè)技術(shù)人員的短缺都需要延長(zhǎng) 這些變壓器的使用壽命。
描述
Hydran M2是經(jīng)濟(jì)的,它是功能強(qiáng)大的一體化變 壓器監(jiān)控裝置,它允許電網(wǎng)和其他用戶(hù)部署對(duì)眾 多變壓器的監(jiān)控,并且會(huì)從它先進(jìn)的特性中得到 收益。
Hydran M2早期故障報(bào)警模型通過(guò)在線故障氣體 和濕度傳感器對(duì)變壓器和其他油浸式設(shè)備早期故 障進(jìn)行監(jiān)控。附加的數(shù)字和模擬量輸入允許對(duì)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(duì)設(shè)備操作和維護(hù)人員提供更多的決策幫助。

HYDRAN-M2
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.
