Production of Six Phase Microcomputer Relay Protection Tester

ZLJB-06 Six phase Microcomputer Relay Protection TesterProduct Features

1. Meet all on-site testing requirements. It can be used to test various traditional relays and protection devices, as well as various modern microcomputer protections, especially for transformer differential protection and backup automatic switching devices, making testing more convenient and efficient.

1) It has a standard six phase current and six phase voltage output simultaneously, with a current of 30A/phase and a voltage of 125V/phase. Six phase current parallel connection can reach 180A.

2. All technical indicators meet the standards of DL/T624-1997 "Technical Conditions for Microcomputer based Test Devices for Relay Protection" issued by the Ministry of Electric Power.

3. Single machine independent operation, built-in high-performance industrial computer, dual core 1.7MHz main frequency, 2GB memory, 32GB hard disk, running Windows XP operating system.

4. The domestic industry is the first to adopt imported brushed stainless steel panels, acrylic keyboards, and touch sensitive mice, overcoming the disadvantages of inflexible and easily damaged operation of trackball mice. It also uses an 8.4-inch TFT true color display screen with a resolution of 800 × 600, making single machine operation convenient and durable.

5. The main control board adopts a DSP+FPGA structure and a 16 bit DAC output, which can generate a high-density sine wave of 2000 points per week for the base wave, greatly improving the quality of the waveform and enhancing the accuracy of the tester.

6. The power amplifier adopts high fidelity linear power amplifier, which ensures the accuracy of small current and the stability of large current.

7. It uses a USB interface to communicate directly with the PC without any adapter cables, making it convenient to use.

8. Can be connected to a laptop to run. Laptops and industrial computers use the same software, so there is no need to relearn the operating methods.

9. Equipped with GPS synchronization test function. The device can be equipped with a built-in GPS synchronization card (optional) and connected to a PC through an RS232 port, enabling two testers to perform synchronous testing in different locations.

10. Equipped with an independent DC auxiliary voltage source output, the output voltages are 110V (1A) and 220V (0.6A) respectively. To be used for relays or protective devices that require DC working power supply.

11. It has software self calibration function, which avoids the need to open the chassis and adjust the potentiometer to calibrate accuracy, greatly improving the stability of accuracy.
