The main control board adopts DSP + FPGA structure, 16-bit DAC output, can generate high-density sine wave of 2000 points per week for the fundamental wave, which is the highest level in the domestic tester, greatly improving the waveform quality and improving the accuracy of the tester. .
Six-phase relay protection tester product features:
1. Classic Windows XP operation interface, friendly man-machine interface, easy and quick operation, in order to facilitate the use of the user, defines a large number of keyboard shortcuts, making the operation "a key in place";
2. High-performance embedded industrial control computer and 8.4 large-screen high-resolution color TFT LCD display can provide rich and intuitive information, including the current working status of the equipment, the next working tips and various help information;
3, equipped with a super-thin industrial keyboard and optical mouse, can be operated like ordinary PC through the keyboard or mouse to complete a variety of operations;
4, equipped with an external USB interface, you can easily perform data access and software maintenance;
5. It can complete the test of all projects without external equipment, automatically display and record test data, and complete the depiction of vector and characteristic curves;
6. Using high-performance D/A converter, the generated waveform has high precision, good linearity, and has good transient response and amplitude-frequency characteristics. In the entire measurement range can ensure that the waveform accuracy and other index requirements;
7, using a unique algorithm, the resulting waveform is accurate, completely different from the waveform generation method of curve fitting, to ensure that the signal is a pure sine wave;
8, can be directly output AC voltage, AC current, DC voltage, DC current, variable amplitude, phase, frequency, 2-20 harmonics;
9. The power amplifier adopts a novel high-power and high fidelity linear amplifier circuit, which has a large output power and low ripple noise. The output voltage of each phase can be 120V and the current can output 20A. When the output current reaches 20A, the output power can reach above 250VA/phase, and the waveform can still be guaranteed without distortion and clipping.
10, with 16 open input and 8 pairs of open contact output output interface. The input input interface can automatically adapt to passive (air contact), active, and automatically adapt to the polarity of the active input, and can work normally within ±250V of the input voltage.
11, to provide a variety of automatic test software modules and GPS synchronization trigger test (optional);
12, GPS synchronization trigger error is less than 50μS;
13, can complete a variety of complex verification work, can easily test and scan a variety of protection settings, playback failure. Can store test data in real time, display vector graphics, print reports, etc.
14, using a carefully designed chassis structure, small size, good heat dissipation, light weight, easy to carry, flow test is convenient;
15, the instrument has self-protection function, the use of a reasonable design of the heat dissipation structure, and has a variety of reliable and complete protection measures and power soft start, and a certain fault self-diagnosis and locking function.
PCD Cutting Tips (Cut Pieces)
PCD cutter pieces (grains) are cut from Pcd Cutting Tool Blanks and are a more efficient and economical cutting service for customers than the wire cutting method, laser cutting.
And the cut grains are welded to saw blades, knives and other tools used for processing wood and metal.
Bohong New Materials can provide different shapes of Pcd Cutting Chips according to customers' requirements, and we are also happy to provide customers with product application consulting services.
