I. Product Introduction
Six-Phase Relay Protection TesterDeveloped in accordance with the "DL/T 624-2010" standard, it can simultaneously output six-phase current and six-phase voltage, with current 6×30A/phase and voltage 6×120V/phase. It features an industrial control computer with Windows XP operating system, an 8.4-inch large-screen high-resolution color TFT LCD display, USB interface, 2-20 harmonics, automatic generation of WORD test reports, frequency range of 10-1000Hz, 8 binary inputs and 4 pairs of binary outputs. In addition to complete testing of microcomputer relay protection devices, it is more convenient for testing microcomputer differential protection devices, with an accuracy of 0.2% and a weight of 22KG.
◆ The user-friendly Windows XP operating system provides a friendly human-machine interface, making operation simple and fast. To facilitate user convenience, a large number of keyboard shortcuts are defined, allowing "one-key operation".
◆ The high-performance embedded industrial control computer and large-screen high-resolution color TFT LCD display provide rich and intuitive information, including the device's current working status, next-step work prompts, and various help information.
◆ Equipped with an ultra-thin industrial keyboard and touch mouse, all operations can be completed via keyboard or mouse just like operating a regular PC.
◆ Equipped with an external USB interface for convenient data storage and software maintenance.
◆ Without the need for external equipment, it can complete testing of all items, automatically display and record test data, and draw vector diagrams and characteristic curves.
◆ Using a high-performance D/A converter, the generated waveform has high precision and good linearity, and possesses good transient response and amplitude-frequency characteristics. Waveform accuracy and other specifications can be guaranteed throughout the entire measurement range.
◆ It can directly output AC voltage, AC current, DC voltage, and DC current, with adjustable amplitude, phase angle, and frequency.
◆ The power amplification section adopts a new type of high-power, high-fidelity linear power amplifier circuit, with large output power and low ripple interference. Even when the output current reaches its maximum, the waveform remains undistorted and unclipped.
◆ The binary input interface can automatically adapt to passive (dry contact) and active inputs, and can automatically adapt to the polarity of active inputs, working normally within an input voltage range of ±250V.
◆ It can complete various complex calibration tasks, conveniently test and scan various protection settings, store test data in real-time, display vector diagrams, and print reports.
◆ With a carefully designed chassis structure, it is compact, well-ventilated, lightweight, easy to carry, and convenient for mobile testing.
◆ The instrument has self-protection functions, adopts a reasonably designed heat dissipation structure, has reliable and comprehensive multiple protection measures and power soft-start, and certain fault self-diagnosis and blocking functions.
