Introduction:
ZX-703 microcomputer relay protection tester,It adopts a high-speed
and high-performance digital signal processor, with fast computing
speed and wide transmission frequency bandwidth. The software uses
double-precision algorithm to generate arbitrary high-precision
waveforms of each phase. Due to the integrated structure, the parts
are tightly combined, the data transmission distance is short and
the structure is compact. Various relays (such as current, voltage,
inverse time limit, power direction, impedance, differential, low
cycle, concurrent period, frequency, DC, intermediate, time, etc.)
and microcomputer protection can be checked, and a complete set of
tests can be simulated for various complex instantaneous,
permanent, and converter faults.
Features:
1. Intelligent host, the host adopts a high-speed and
high-performance digital signal processor, with fast computing
speed and wide transmission frequency bandwidth. The software uses
double-precision algorithm to generate arbitrary high-precision
waveforms of each phase. Due to the integrated structure, the parts
are tightly combined, the data transmission distance is short and
the structure is compact.
2. The unit is operated independently by a convenient and flexible
rotating mouse through the large-screen LCD display, and the
complete set of Chinese display is displayed. Most of the on-site
test and verification work can be completed, and various relays
(such as current, voltage, reverse time limit, power direction,
impedance, differential, low cycle, concurrent period, frequency,
DC, intermediate, time, etc.) and microcomputer protection can be
checked, and a complete set of tests can be simulated for various
complex instantaneous, permanent, and converter faults.
3. Connect to the computer to run. Through the full set of Chinese
operating software on the Windows platform, various large-scale,
complex and more automated verification work can be carried out.
Various protection settings can be easily tested and scanned. Test
data can be stored in real time, display vector diagrams, draw
fault waveforms, print reports online, etc.
4. Large-screen LCD display. This unit uses a large-screen
high-resolution graphic LCD display. All operation processes are
set on the display. The operation interface and test results are
displayed in Chinese, and the display is intuitive and clear.
5. "Fool-style" operation, using an advanced controller "rotate
mouse", greatly simplifying the structure of the operation part,
making the operation simple, quick and easy to master.
6. The output stage uses new high-fidelity amplifiers, which can be
used as current output and voltage output. The output power is
large, the accuracy is good, and the reliability is high.
7. Current and voltage are directly output. The phase voltage and
phase current are output by DC amplifier, which can directly output
AC voltage, AC current, DC voltage, DC current, and variable angle
and frequency, and can superimpose 1-20 harmonics.
8. Self-protection, adopts a reasonably designed heat dissipation
structure, and has a variety of reliable and complete protection
measures and power supply soft start, as well as certain fault
self-diagnosis and locking functions.
9. It has an independent dedicated DC power output device and is
equipped with a dedicated 110V or 220V DC power output.
10. Rich contacts, with 8 contact inputs and 4 empty contact
outputs. The input contact is compatible with the empty contact and
0-250V potential contact, which can be automatically identified
intelligently.
11. The host is integrated with a single machine structure and
operates with an AC 220V power supply. Small size, light weight,
easy to carry, easy to flow test.
12. It has a high cost-effectiveness and is a cross-professional
joint design product, integrating advanced scientific and
technological achievements from multiple majors. It has the
performance of a large tester and the price of a small tester, and
has a high performance-price ratio.
