TKJB-703 microcomputer relay protection tester is also called three-phase microcomputer relay protection tester and three-phase microcomputer relay protection calibrator. The three-phase microcomputer relay protection tester is a special power test for relay protection

instrument. The three-phase microcomputer relay protection tester has 4-phase voltage and 3-phase current output, which is suitable for testing various types of relay protection devices. TKJB-703 microcomputer relay protection tester adopts high-speed and high-performance data

The word signal processor has fast calculation speed and wide transmission frequency. The software applies double-precision algorithm to generate arbitrary high-precision waveforms of each phase. Due to the integrated structure, each part is tightly integrated, and the data transmission distance is

It is short and compact.

    1. Standard 4-phase voltage and 3-phase current output. With 4-phase voltage and 3-phase current output, it is convenient to carry out various combination outputs for various types of protection tests. Each phase voltage can output 120V, current

Three can output 120A, the 4th phase voltage Ux is a multi-function voltage item, which can be set to 4 kinds of 3U0 or check synchronous voltage, or output at any certain voltage value;

       2. The stand-alone operation is convenient. The stand-alone is operated by a convenient and flexible rotating mouse through the large-screen LCD display, all displayed in Chinese. It can complete most of the field test and verification work, and can be used for various

The relay and microcomputer protection are verified, and various complex transient, permanent, and conversion faults can be simulated for a whole set of tests. It can be used after booting, and the operation is convenient and quick;

       3. Double operation mode, connected to the computer to run. Through a full set of Chinese operating software on the Windows platform, various large-scale, complex and more automated calibration tasks can be carried out, which can be easily measured.

Test and scan various protection settings, can store test data in real time, display vector diagrams, draw fault waveforms, print reports online, etc.;

       4. The software is powerful and can complete various large-scale and complex calibration tasks with high degree of automation, such as three-phase differential test, factory power quick cut, standby automatic switching test, line protection inspection and simultaneous reclosure, etc.

It can easily test and scan various protection settings, perform fault playback, store test data in real time, display vector diagrams, print reports online, etc.;

       5. Rich switch contacts 7-way contact input and 2 pairs of empty contact output. The input contacts are empty contacts and compatible with 0～250V potential contacts, which can be intelligently and automatically identified. Input and output contacts can be based on

Users need to expand;

       6. Large-screen LCD display This machine uses a 320×240 dot-matrix large-screen high-resolution graphic LCD display. All operation processes are set on the display. The operation interface and test results are both Chinese.

The display is intuitive and clear;

       7. The self-protection adopts a reasonably designed heat dissipation structure, and has a variety of reliable and complete protection measures, soft start of the power supply, and certain fault self-diagnosis and lockout functions;

       8. With independent dedicated DC power output, the device is equipped with a 110V and 220V dedicated DC power output;

       9. High cost performance is a cross-professional joint design product, which integrates multi-professional advanced scientific and technological achievements. Both the performance of a large-scale tester and the price of a small-scale tester have a high performance price

ratio.
