Overview

The six phase industrial control relay protection testing device, BYJB-C relay protection instrument, uses a high-speed digital control processor as the output core, and applies a 32-bit dual precision algorithm on the software to generate arbitrary high degree waveforms for each phase. Due to the use of an integrated structure, the various parts are tightly combined, the data transmission distance is short, and the structure is compact. Overcoming the problem of fewer output waveform points caused by long data communication lines and narrow frequency bands in laptop controlled measurement and control instruments.

1Six phase industrial control relay protection testing deviceKey Features:

1. Flexible combination of voltage and current output can achieve 6-phase voltage and 6-phase current, and can be freely combined to achieve conventional 4-phase voltage, 3-phase current type, 6-phase voltage type, 6-phase current type, and 12 phase output modes. It is compatible with various traditional testing methods, and can also be conveniently used for three-phase transformer differential testing, plant power fast switching, and backup automatic switching testing.

2. Operation method: The device can be directly connected to a laptop or desktop computer for convenient, fast, and stable performance.

3. New high fidelity linear power amplifier: The output end has always insisted on using high fidelity and high reliability modular linear power amplifiers, rather than switch type power amplifiers, which have better performance. It will not cause high or medium frequency interference on the test site, and ensures smooth waveform accuracy from high current to low current throughout the entire process.

4. High performance host: The output part is controlled by DSP, with fast operation speed, strong real-time digital signal processing capability, wide transmission frequency band, and high-resolution D/A conversion control. The output waveform has high accuracy, low distortion, and good linearity. The device adopts a large amount of technology and precision component materials, and has undergone specialized structural design, resulting in a small volume, light weight, comprehensive functions, easy portability, and can work immediately after startup. Flow testing is very convenient.

5. Powerful software functions: It can complete various large-scale complex verification tasks with high automation level, easily test and scan various protection settings, perform fault playback, store test data in real time, display vector graphics, print reports online, etc. 6-phase current can facilitate three-phase differential protection testing.

6. With independent DC power output: equipped with one 110V and 220V adjustable DC power output.

7. Complete interface: The device is equipped with a USB communication port, which can communicate with computers and other external devices.

8. Comprehensive self-protection function: The heat dissipation structure is designed reasonably, the hardware protection measures are reliable and complete, it has power soft start function, software self diagnosis of faults, and output locking function.
