Profile:
The KDJB-40A microcomputer relay protection tester uses a high-speed and high-performance digital control processor as the control microcomputer, and applies a dual precision algorithm on the software to generate high-precision 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.
Features:
1. Standard 4-phase voltage and 3-phase current output: With 4-phase voltage and 3-phase current output, it can easily perform various combination outputs for various types of protection tests. Each phase voltage can output 120V, and the current can output 120A in three parallel. The fourth phase voltage Ux is a multifunctional voltage item, which can be set as four types of 3U0 or detected for synchronous voltage, or output for a certain voltage value.
2. Easy single machine operation: The single machine is operated by a convenient and flexible rotating mouse through a large LCD screen, displayed in Chinese. It can complete most of the on-site testing and verification work, verify various relays and microcomputer protections, and simulate complex instantaneous, long-term, and conversion faults for whole group testing. Ready to use upon startup, easy and fast to operate.
3. Dual operation mode: Connect the computer to run Chinese operating software on the Windows platform, which can perform various large-scale, complex, and highly automated verification tasks. It can easily test and scan various protection settings, store test data in real time, display vector graphics, draw fault waveforms, and print reports online.
4. Strong software functionality: It can complete various large-scale complex verification tasks with high automation level, such as three-phase differential test, plant power fast switching, backup automatic switching test, line protection check synchronous reclosing, etc. It can easily test and scan various protection settings, perform fault playback, store test data in real time, display vector graphics, and print reports online.
5. Rich switch contacts: 7 contact inputs and 2 pairs of empty contact outputs. The input contacts are compatible with empty contacts and 0-250V potential contacts, and can be intelligently and automatically recognized. The input and output contacts can be expanded according to user needs.
6. Large screen LCD display: This machine adopts a 320 × 240 dot matrix large screen high-resolution graphic LCD display. The operation process is set on the display screen, and the operation interface and test results are displayed in Chinese, with intuitive and clear display.
7. Self protection: adopting a reasonably designed heat dissipation structure, with reliable and comprehensive multiple protection measures, power soft start, and certain fault self diagnosis and locking functions.
