Features:
According to the user's functional requirements for the stepless
adjustable AC high-current test equipment: do a temperature rise
test at the output full load of three-phase AC 5000A, and run for
more than 8 hours:
- Built-in high-configuration industrial computer, using programmable
controller Siemens PLC as the central processor, real-time scanning
of AC signals, realizing comprehensive monitoring and closed-loop
control, and designing password setting management, only those who
have obtained the corresponding operating authority can perform
certain Functional operation.
- Using intelligent sensors that support fieldbus technology to
realize the full digitization of data transmission. The display and
operation unit uses a touch-type color LCD screen, a full English
menu, a clear and intuitive interface, and simple operation
convenience. The test does not require any external auxiliary
equipment, fully automatic control, fool-like operation, fast,
simple and convenient.
- The test method of this instrument has two methods: automatic test
and manual test. Only need to set a simple test current and time.
With automatic steady current system.
- Only need to set the target current without manual monitoring. To
set the test, current and step length, eliminating the tedious
labor of manual voltage adjustment, manual recording, and drawing
curves, reducing labor intensity and improving work efficiency.
After finishing, just read the data to the computer to check.
- There is an automatic alarm function that exceeds the limit value.
It has reliable self-protection functions for overheating,
overcurrent, overvoltage and short-circuit. The protection of the
AC voltage regulator should adopt the dual protection of
microcomputer automatic protection control and mechanical
micro-motion limit switch to ensure the normal operation of the
constant current power supply and improve the safety and
reliability of the product.
- Humanized interface, friendly software interface, full English
operation interface, the control software has data recording, and
can store current and temperature waveforms, data management,
reports, printing and other practical functions. Parameter settings
are all completed in the software. Analyze the relationship between
current and temperature more intuitively. Make all data and test
analysis results clear at a glance. During the test, the target
current is automatically tracked, the output current is
automatically stabilized, and the three-phase current is
automatically adjusted; after the test is completed, it
automatically returns to the zero position.
- Automatically adjust the AC constant current source to meet GB
7251.1 ~ GB 7251.5 standard medium and low voltage complete
switchgear (control cabinet containing multiple outputs such as
GCK, MNS, etc.) temperature rise test, automatically adjust the AC
constant current source should be able to in the temperature rise
test Realize the parallel operation of multiple constant current
power supplies (a copy of the proof materials that users use
multiple constant current sources to operate in parallel, such as
temperature rise test of GCK or MNS, etc.)
- Equipped with a three-phase automatic balance system to ensure
three-phase balanced output. The output current sampling adopts
0.2S-class transformers and the latest current power electronic
technology. It has strong anti-interference ability and high output
accuracy,up to 0.5 level.
- Equipped with a precision adjustment menu, users can adjust the
error value by themselves. The programmable AC constant current
power supply can realize full intelligent calibration, and
automatically generate multi-stage correction coefficients within
the adjustable range of the device to ensure the constant current
power supply accuracy.
- The test module can be customized according to user requirements.
- Built-in power compensation system.
