Test the operating value, return value, and operating time of a single conventional relay.

End value

Multifunctional microcomputer-based relay protection test device Its main features are as follows:

Classic Windows XP operation interface, friendly human-machine interface, simple and fast operation. To facilitate user use, a large number of keyboard shortcuts are defined, making operation "one-key到位"; high-performance embedded industrial control computer and 8.4-inch large-screen high-resolution color TFT LCD display can provide rich and intuitive information, including the current working status of the device, next-step work prompts, and various help information; equipped with an ultra-thin industrial keyboard and optical mouse, all operations can be completed through the keyboard or mouse just like operating a normal PC; equipped with an external USB interface for convenient data storage and software maintenance; without external devices, it can complete all project tests, automatically display and record test data, and complete the drawing of vector diagrams and characteristic curves; using high-performance D/A converter, the generated waveform has high precision, good linearity, and good transient response and amplitude-frequency characteristics. Waveform accuracy and other indicators can be guaranteed throughout the entire measurement range; using a unique algorithm, the generated waveform is precise, completely different from the curve-fitting waveform generation method, ensuring the signal is a pure sine wave; can directly output AC voltage, AC current, DC voltage, DC current, with variable amplitude, phase, frequency, and 2 to 20 harmonics; the power amplification part adopts a new type of high-power high-fidelity linear power amplifier circuit, with large output power and low ripple interference. Each phase voltage can output 120V, and current can output 30A. When the output current reaches 30A, the waveform can still be guaranteed without distortion or peak clipping; it has 16 open input quantity inputs and 8 pairs of dry contact output quantity output interfaces. The open input quantity input interface can automatically adapt to passive (dry contact) and active, and can automatically adapt to the polarity of active input, working normally within the input voltage range of ±250V; provides various automatic test software modules and GPS synchronous trigger test (optional), etc.; GPS synchronous trigger error is less than 50μS; can complete various complex calibration tasks, conveniently test and scan various protection settings, and perform fault replay. It can store test data in real-time, display vector diagrams, print reports, etc.; using a carefully designed chassis structure, small size, good heat dissipation, light weight, easy to carry, convenient for mobile testing; the instrument has self-protection function, adopts a reasonably designed heat dissipation structure, and has reliable and complete multiple protection measures and power soft start, as well as certain fault self-diagnosis and blocking functions.
