KD630 microcomputer relay protection tester

Product Introduction

KD630 microcomputer relay protection testerBased on the reference to DL/T624-1997 "Technical Conditions for Microcomputer based Relay Protection Test Equipment" issued by the Ministry of Electric Power, extensive listening to user opinions, summarizing the advantages and disadvantages of similar products in China, and fully utilizing modern microelectronics technology and devices, a new type of miniaturized microcomputer relay protection tester is developed. The microcomputer relay protection tester adopts a single machine independent operation and can also be connected to a laptop for operation. The host adopts DSP+FPGA structure, true 16 bit DAC output, built-in new modular high fidelity linear high-power amplifier, built-in 8.4-inch TFT true color display screen with a resolution of 800 × 600, and high-end industrial keyboard and mouse. Windows XP operating system, features *. Small size and high precision. This microcomputer relay protection tester not only has the performance and functions of a large tester, but also has the advantages of a small and flexible tester, easy operation, and high reliability, with a high cost performance ratio. It is a handy tool for relay protection workers.

KD630 microcomputer relay protection tester

1. Meet all on-site testing requirements. This instrument has a standard four phase voltage and three-phase current output, with a voltage of 125V/phase and a current of 40A/phase. Three phase parallel connection can reach up to 120A. It can be used to test various traditional relays and protection devices, as well as various modern microcomputer protections, especially for transformer differential power protection and backup automatic switching devices, making testing more convenient and efficient.
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. 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 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.
