美國(guó)SEL繼電器正確使用方法
SEL繼電器特色應(yīng)用,SEL綜合保護(hù)裝置連接sel-700g發(fā)電機(jī)保護(hù)繼電器過(guò)小，介質(zhì)，或*小學(xué)和備份保護(hù)大型發(fā)電機(jī)。sel-700gt提供符合IEEE 1547標(biāo)準(zhǔn)的聯(lián)絡(luò)線保護(hù)解決方案的分布式發(fā)電。增加中性點(diǎn)電壓連接提供百分之100個(gè)定子接地保護(hù)，基于第三次諧波電壓測(cè)量。連接的中性點(diǎn)電流輸入提供了堅(jiān)實(shí)的接地或電阻接地機(jī)器的保護(hù)。
autosynchronizer取代外部發(fā)電機(jī)控制和同步繼電器與內(nèi)置的自動(dòng)同步功能。發(fā)電機(jī)的頻率，電壓，相位控制是自動(dòng)同步的，并連接到電力系統(tǒng)。SEL繼電器監(jiān)測(cè)發(fā)電機(jī)的同步過(guò)程中使用發(fā)電機(jī)啟動(dòng)報(bào)告和基于PC的示波器。
SEL繼電器電流差動(dòng)保護(hù)比率制動(dòng)差動(dòng)元件應(yīng)用敏感和奔放的元素，隨著同步檢查，每赫茲元素伏，整個(gè)單元保護(hù)發(fā)電機(jī)和升壓變壓器。可選電流差動(dòng)元件檢測(cè)定子故障，使用一個(gè)安全的，敏感的電流差動(dòng)功能。美國(guó)SEL電力變壓器和CT連接補(bǔ)償允許機(jī)組升壓變壓器被列入發(fā)電機(jī)差動(dòng)區(qū)。
sel - 501雙普遍過(guò)電流繼電器是兩個(gè)成套保護(hù);既可以配置為五個(gè)基本繼電器之一。SEL繼電器除了我們能介紹中文的詳細(xì)介紹，同時(shí)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*，
