Three phase Relay protection tester/relay test set protection relay tester
Main feature
1. The standard 4-phase voltage and 3-phase current output has a 4-phase voltage and 3-phase current output, which can be easily carried out a variety of combined outputs for various types of protection tests. Each phase voltage can output 300V, current three and can output 90A, the fourth phase voltage Ux is a multi-function voltage item, can be set to 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. It can complete most of the field test and verification work, can verify all kinds of relays and microcomputer protection, and can simulate all kinds of complex transient, permanent and transformational faults for whole group tests. Boot can be used, easy to operate.
3. Dual operation mode, connect the computer to run through the Chinese operating software on the Windows platform, can carry out a variety of large complex and more automated verification work, can easily test and scan a variety of protection set values, can store test data in real time, display vector graphics, draw fault waveform, online printing reports, etc.
4. It can complete a variety of large and complex calibration work with high degree of automation, such as three-phase differential test, plant power quick cutting, ready self-feeding test, line protection inspection and reclosing at the same time, etc. It can easily test and scan various protection values, fault playback, real-time storage of test data, display vector diagram, online printing report, etc.
5. Supply 10 contact inputs and 8 air contact outputs. Input contacts are null contacts and 0 ~ 250V potential contacts compatible, intelligent automatic recognition. Input and output contacts can be expanded according to user needs.
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.
