Precautions
1. In order to prevent the machine body from inducing static electricity during the operation of the instrument, the host must be reliably grounded through the grounding terminal before the test;
2. Pay attention to safety when outputting voltages above 36V to prevent electric shock accidents;
3. It is strictly forbidden to short-circuit the voltage test channel and open the current test channel. It is strictly forbidden to introduce external AC and DC power into the voltage source, current source, and output jack of the instrument, otherwise the instrument may be damaged;
4. In order to ensure the accuracy of the test, the outer loop of the protection device should be disconnected, and the voltage N and the current N should be at the same point and common ground;
5. Pay attention to keeping the air flow of the vents on the side of the chassis unblocked, please do not block the vents, so as not to affect the heat dissipation;
6. After single-phase output or parallel output of large current, ensure that the instrument has at least 30 seconds of heat dissipation before proceeding to the next test;
7. During the test, please do not switch the power frequently, so as not to damage the instrument or reduce the test accuracy;
8. During the test, if an abnormal situation is encountered, the power supply should be cut off immediately;
9. Do not place the instrument in the open and get wet by rain;
10. When the instrument works abnormally, please contact the manufacturer in time and do not repair it yourself.
main feature
1. Meet all test requirements on site. This instrument has standard six-phase voltage, six-phase current output, voltage 125V/phase, current 30A/phase. The six-phase parallel connection can reach 180A. It can test various traditional relays and protection devices, as well as various modern microcomputer protections, especially for transformer differential power protection and automatic switching devices. The test is more convenient and perfect.
2. Various technical indicators fully meet the standards of DL/T624-1997 "Technical Conditions for Microcomputer-based Relay Protection Test Devices" issued by the Ministry of Electric Power.
3. Classic Windows XP operation interface, friendly man-machine interface, easy and quick operation; high-performance embedded industrial control computer and 8.4-inch TFT true color display with 800×600 resolution can provide rich and intuitive information, including equipment current Working status and various help information.
4. The native Windows XP system comes with a recovery function to avoid system crashes caused by illegal shutdown or misoperation.
5. Equipped with ultra-thin industrial keyboard and optical mouse, various operations can be completed by keyboard or mouse just like ordinary PC.
6. The main control board adopts DSP+FPGA structure, 16-bit DAC output, and can generate 2000 high-density sine waves per week for the fundamental wave, which greatly improves the quality of the waveform and the accuracy of the tester.
7. The power amplifier adopts a high-fidelity linear power amplifier, which not only ensures the accuracy of small currents, but also ensures the stability of large currents.
8. The USB interface is used to communicate directly with the PC, without any transfer cables, which is convenient to use.
9. Can be connected to a laptop computer (optional) to run. The notebook computer and the industrial computer use the same set of software, so there is no need to relearn the operation method.
10. With GPS synchronization test function. The device can have a built-in GPS synchronization card (optional) connected to a PC through an RS232 port, enabling two testers to perform synchronous adjustment tests in different places.
11. Equipped with independent dedicated DC auxiliary voltage source output, the output voltage is 110V (1A), 220V (0.6A). It can be used for relays or protection devices that require DC working power.
12. With software self-calibration function, it avoids the need to open the case and adjust the potentiometer to calibrate the accuracy, thereby greatly improving the stability of the accuracy.
