Technical characteristics
The intelligent host adopts a high-speed and high-performance digital signal processor with fast operation speed and wide transmission frequency band. The software uses a dual precision algorithm to generate high-precision waveforms for each phase. Due to its integrated structure, each part is tightly integrated, with short data transmission distance and compact structure.
The standalone operation device is operated by a convenient and flexible rotating mouse through a large LCD screen, with Chinese display. It can complete most of the on-site testing and verification work, and can verify various relays (such as current, voltage, inverse time, power direction, impedance, differential, low cycle, synchronization, frequency, DC, intermediate, time, etc.) and microcomputer protection. It can also simulate various complex instantaneous and conversion faults for whole group testing.
It can complete various large-scale and complex verification tasks with high automation levels, such as differential testing, backup automatic switching testing, line protection synchronous reclosing, etc. It can conveniently test and scan various protection settings, store test data in real-time, display vector maps, etc.
The large screen LCD display screen adopts a large screen high-resolution graphic LCD display screen, and the operation process is set on the display screen. The operation interface and test results are displayed in Chinese, making the display intuitive and clear.
The "foolproof" operation adopts a controller called "rotating mouse", which has multiple shortcut key operations, greatly simplifying the structure of the operation part, making the operation simple, fast, and easy to master.
The output stage of the new high fidelity power amplifier adopts a new high-power modular high fidelity power amplifier component, which can output both current and voltage, with high output power, good accuracy, and high reliability.
Direct output of phase voltage and phase current using a DC power amplifier output method can directly output AC voltage, AC current, DC voltage, and DC current, with variable angle and frequency, and can stack 1-20 harmonics.
Self protection adopts a reasonably designed heat dissipation structure, with reliable and comprehensive multiple protection measures, power soft start, and certain fault self-diagnosis and locking functions.
Equipped with an independent dedicated DC power output device with a dedicated 110V or 220V DC power output.
Rich contacts with 8 contact inputs and 4 empty contact outputs. The input contact is compatible with the null contact and the 0-250V potential contact, which can be intelligently and automatically recognized.
The integrated single machine structure of the host adopts an AC 220V power supply for operation. Small size, light weight, easy to carry, and convenient for flow testing.
High cost-effectiveness is a cross disciplinary joint design product that combines multiple professional technological achievements. Having both the performance of large testers and the price of small testers, it has a high performance to price ratio.
