Manufacturer of single-phase three-phase six phase relay protection tester

Manufacturer of single-phase three-phase six phase relay protection testerProduct Introduction
The TPJBC-6680 microcomputer relay protection tester, professionally manufactured by Yangzhou Topu Electric Technology Co., Ltd., is a new type of miniaturized microcomputer relay protection tester that uses modern microelectronics technology and power electronics technology. It adopts popular DSP and switch amplifier technology, and its single machine independent operation function is already very powerful. Coupled with PC software, it can be connected to a computer for operation, adding to its functionality. Its volume and weight are only half of traditional testers. The design concept of this instrument has made it reach the domestic level.
The TPJBC-6680 microcomputer relay protection tester 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, meeting 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. Meeting all on-site testing requirements, it can 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 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, main frequency 300-600MHz, 512M memory, hard disk 4-12GB, running Windows XP operating system.
4. Domestically, we are the first to adopt imported brushed stainless steel panels, stainless steel keyboards, and touch sensitive mice, overcoming the disadvantages of inflexible and easily damaged operation of trackball mice. We have also chosen an 8.4-inch TFT true color display screen with a resolution of 800 × 600, making the overall operation of the single machine easy 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.
