美國SEL繼電器正確使用方法
SEL繼電器特色應用,SEL綜合保護裝置連接sel-700g發(fā)電機保護繼電器過小，介質，或*小學和備份保護大型發(fā)電機。sel-700gt提供符合IEEE 1547標準的聯(lián)絡線保護解決方案的分布式發(fā)電。增加中性點電壓連接提供百分之100個定子接地保護，基于第三次諧波電壓測量。連接的中性點電流輸入提供了堅實的接地或電阻接地機器的保護。
autosynchronizer取代外部發(fā)電機控制和同步繼電器與內(nèi)置的自動同步功能。發(fā)電機的頻率，電壓，相位控制是自動同步的，并連接到電力系統(tǒng)。SEL繼電器監(jiān)測發(fā)電機的同步過程中使用發(fā)電機啟動報告和基于PC的示波器。
SEL繼電器電流差動保護比率制動差動元件應用敏感和奔放的元素，隨著同步檢查，每赫茲元素伏，整個單元保護發(fā)電機和升壓變壓器?？蛇x電流差動元件檢測定子故障，使用一個安全的，敏感的電流差動功能。美國SEL電力變壓器和CT連接補償允許機組升壓變壓器被列入發(fā)電機差動區(qū)。
sel - 501雙普遍過電流繼電器是兩個成套保護;既可以配置為五個基本繼電器之一。SEL繼電器除了我們能介紹中文的詳細介紹，同時我們還能提供正面英文的是
Comprehensive Generator Protection—Connect the SEL-700G Generator Protection Relay across small, medium, or large generators for complete primary and backup protection. The SEL-700GT provides an IEEE 1547 compliant intertie protection solution for distributed generation. Adding the neutral voltage connection provides 100 percent stator ground protection, based on third-harmonic voltage measurements. Connecting the neutral current input provides protection for solidly grounded or resistance-grounded machines.
Autosynchronizer—Replace external generator control and synchronizer relays with the built-in automatic synchronizer function. Frequency, voltage, and phase control of the generator are automatically synchronized and connected to the power system. Monitor the generator synchronization process using generator start reports and the PC-based synchroscope.
Current Differential Protection—Apply sensitive percentage-restrained current differential elements and an unrestrained element, along with synchronism check and volts-per-hertz elements, across the entire unit to protect both the generator and the step-up transformer. Optional current differential elements detect stator faults using a secure, sensitive current differential function. Power transformer and CT connection compensation allows the unit step-up transformer to be included in the generator differential zone.  SEL繼電器正確的解決方案，SEL*，
