Relay protection tester
Ciri utama
1. The standard 4-phase voltage and 3-phase current output has a 4-phase voltage and 3-phase current output, yang boleh dijalankan dengan mudah pelbagai keluaran gabungan untuk pelbagai jenis ujian perlindungan. Each phase voltage can output 300V, semasa tiga dan boleh mengeluarkan 90A, the fourth phase voltage Ux is a multi-function voltage item, boleh ditetapkan kepada 4 kinds of 3U0 or check the same period voltage, or a voltage value of the case output.
2. The single machine is easy to operate. The single machine is operated by the convenient and flexible photoelectric trackball mouse through the large-screen LCD screen, and all Chinese characters are displayed. Ia boleh menyelesaikan kebanyakan ujian lapangan dan kerja pengesahan, boleh mengesahkan semua jenis geganti dan perlindungan mikrokomputer, dan boleh mensimulasikan semua jenis sementara kompleks, kerosakan kekal dan transformasi untuk keseluruhan ujian kumpulan. Boot boleh digunakan, mudah dikendalikan.
3. Dual operation mode, connect the computer to run through the Chinese operating software on the Windows platform, boleh menjalankan pelbagai kerja pengesahan besar yang kompleks dan lebih automatik, boleh menguji dan mengimbas pelbagai nilai set perlindungan dengan mudah, boleh menyimpan data ujian dalam masa nyata, paparan grafik vektor, lukis bentuk gelombang sesar, laporan percetakan dalam talian, dan lain-lain.
4. Ia boleh menyelesaikan pelbagai kerja penentukuran yang besar dan kompleks dengan tahap automasi yang tinggi, seperti ujian pembezaan tiga fasa, pemotongan cepat kuasa loji, ujian makan sendiri sedia, pemeriksaan perlindungan talian dan penutupan semula pada masa yang sama, dan lain-lain. It can easily test and scan various protection values, main balik kesalahan, penyimpanan data ujian masa nyata, display vector diagram, online printing report, dan lain-lain.
5. Bekalan 10 contact inputs and 8 air contact outputs. Kenalan input adalah kenalan nol dan 0 ~ 250V potensi kenalan serasi, pengecaman automatik pintar. Hubungan input dan output boleh dikembangkan mengikut keperluan pengguna.
6. Large screen TFT display The machine adopts 800×600 dot matrix large screen TFT high resolution true color liquid crystal display, the operation process is set on the display, the operation interface and test results are displayed in Chinese, the display is intuitive and clear.
7. Self-protection adopts reasonable design of heat dissipation structure, and has a variety of reliable and perfect protection measures and power soft start, and a certain fault self-diagnosis and blocking function.
8. With dedicated DC power output device with one 110V and 220V dedicated DC power output.
9. High cost performance is a cross-professional joint design product, which integrates multi-professional scientific and technological achievements. Both the performance of a large tester, and the price of a small tester, with a high performance-to-price ratio.
