    SYJBC-880 six-phase microcomputer relay protection tester
    Introduction:
       The six-phase microcomputer relay protection tester uses the 6000 series DSP controller as the core, and the FPGA programmable logic device outputs the waveform. Due to the DDS hardware output waveform technology, the waveform frequency and phase accuracy are quite high. At the same time, the system The industrial computer communication directly adopts the USB2.0 interface, which makes the data communication stable and reliable.
       The six-phase relay protection tester uses a high-precision D/A converter and an active low-pass filter to smooth the output waveform and excellent amplitude-frequency characteristics. At the same time, the control system also retains 12 12-bit A/D conversion circuits, which can collect 12 analog output waveforms in real time and display the actual output waveform, amplitude and phase on the screen through software.
       The current and voltage are directly coupled to the high-performance linear amplifier, so that the current and voltage sources can directly output AC and DC waveforms, and can output various combinations of waveforms such as square waves and harmonics by software. Waveforms, etc., can better simulate the current and voltage characteristics of various short-circuit faults.
     Features:
    1. Meet all test requirements on site.
    The six-phase microcomputer relay protection tester has a standard six-phase current, six-phase voltage output simultaneously, current 30A/phase, voltage 125V/phase. The six-phase current can be connected in parallel to 180A. It can test various traditional relays and protection devices, and can also carry out various tests on modern microcomputer protection. Especially for transformer differential protection and self-injection devices, the test is more convenient and perfect.
    2. Various technical indicators have fully met the standards of DL/T624-1997 “Technical Conditions for Relay Protection Microcomputer Type Test Equipment” issued by the Ministry of Power.
    3, stand-alone operation, built-in high-performance industrial computer, frequency 300--600MHz, memory 128M, hard disk 6--12G, running Windows XP operating system.
    4, the domestic industry first adopts imported brushed stainless steel panel, stainless steel keyboard, and touch mouse, which overcomes the shortcomings of the trackball mouse inflexible and easy to damage, and selects 8.4 inch, resolution 800×600 TFT color The display makes the overall operation of the single unit easy and durable.
    5. The main control board adopts DSP+FPGA structure and 16-bit DAC output. It can generate 2000-point high-density sine wave for the fundamental wave, which greatly improves the quality of the waveform and improves the accuracy of the tester.
    6. The power amplifier adopts high-fidelity linear power amplifier, which not only ensures the accuracy of small current, but also ensures the stability of large current.
    7. The six-phase microcomputer relay protection tester uses the USB interface to communicate directly with the PC. It does not require any patch cords and is convenient to use.
    8, can be connected to the laptop to run. The laptop and the industrial computer use the same software, no need to re-learn the operation method.
    9, with GPS synchronization test function. The device can be equipped with a built-in GPS sync card (optional) connected to the PC through the RS232 port, enabling simultaneous synchronization of the two testers.
    10. It is equipped with independent dedicated DC auxiliary voltage source output, and the output voltage is 110V (1A) and 220V (0.6A) respectively. Used for relays or protection devices that require DC operating power.
    11. The six-phase microcomputer relay protection tester has a software self-calibration function, which avoids the need to open the chassis by adjusting the potentiometer to calibrate the accuracy, thereby greatly improving the stability of the accuracy.
