ZSJB-1000 Microcomputer Relay Protection Tester

ZSJB-1000 Microcomputer Relay Protection Tester

Product Features

1. Meet all on-site testing requirements. It has a standard six phase current and six phase voltage output simultaneously, with a current of 30A/phase and a voltage of 120V/phase. Six phase current parallel connection can reach 150A. 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.

2. All technical indicators fully 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. Classic Windows XP operating interface, user-friendly human-machine interface, easy and fast operation; A high-performance embedded industrial control computer and an 8.4-inch TFT true color display screen with a resolution of 800 × 600 can provide rich and intuitive information, including the current working status of the device and various help information.

4. The Windows XP system comes with a built-in recovery function to prevent system crashes caused by illegal shutdowns or misoperations.

5. Equipped with an ultra-thin industrial keyboard and optical mouse, various operations can be completed through the keyboard or mouse just like operating a regular PC.

6. 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.

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

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

9. Can be connected to a laptop (optional) for operation. Laptops and industrial computers use the same software, so there is no need to relearn the operating methods.

10. 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.

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

12. 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.
