Audited Supplier Industrial computer digital relay second check instrument testing machine/Relay protection calibration tester
Product overview
KDJB1200 microcomputer relay protection calibrator is a new miniaturized microcomputer relay protection tester based on the "Technical Conditions of Microcomputer relay protection test device (Discussion draft)" issued by the Ministry of Electric Power, listening to the views of users, summarizing the advantages and disadvantages of similar domestic products, and making full use of modern microelectronics technology and devices.
KDJB1200 microcomputer relay protection calibrator adopts the structure of independent operation of a single machine and can also be connected to a laptop computer. The host built-in a new generation of high-speed digital signal processor microcomputer, true 16-bit DAC module, a new modular high-fidelity high-power amplifier, with large screen LCD display and flexible and convenient rotary mouse controller. The independent operation of a single machine has a strong function, can carry out most tests, and the connected computer has a stronger operating function. It has the performance and function of a large tester, and has the advantages of small, flexible, easy to operate, high reliability, and high performance-price ratio. It is a good tool for care workers.
Product characteristics
1, the classic Windows XP operating interface, human-machine interface friendly, easy and quick operation, in order to facilitate the use of users, defined a large number of keyboard shortcuts, so that the operation "one key in place";
2, high-performance embedded industrial control computer and 8.4 "large screen high resolution color TFT LCD display, can provide rich intuitive information, including the current working status of the equipment, the next work tips and various help information;
3, equipped with industrial keyboard and photoelectric mouse, can be operated as an ordinary PC through the keyboard or mouse to complete various operations;
4, equipped with external USB interface, can easily carry out data access and software maintenance;
5, can complete the project test without external equipment, automatically display and record test data, complete the description of vector diagram and characteristic curve;
6, the use of high-performance D/A converter, the generated waveform accuracy is high, good linearity, and has good transient response and amplitude frequency characteristics. In the measuring range can ensure the waveform accuracy and other indicators;
7, the algorithm used, the generated waveform is accurate, different from the waveform generation method of curve fitting, to ensure that the signal is pure sine wave;
8, can directly output AC voltage, AC current, DC voltage, DC current, variable amplitude, phase, frequency, 2 ~20 harmonics;
9, the power amplifier part adopts a new high-power high-fidelity linear power amplifier circuit, the output power is large, the ripple interference is small, each phase voltage can output 120V, the current can output 30A. When the output current reaches 30A, the waveform can still ensure no distortion and no clipping;
10, with 16 open input and 8 air contact output interface. The open input interface can automatically adapt to passive (null contact), active, and can automatically adapt to the polarity of the active input, and can work normally within the input voltage range of ±250V;
11, provide a variety of automatic test software modules and GPS synchronous trigger test (optional);
12, GPS synchronization trigger error is less than 50μS;
13, can complete a variety of complex calibration work, can easily test and scan a variety of protection set values, fault playback. It can store test data in real time, display vector diagram, print reports, etc.
14, the use of well-designed chassis structure, small size, good heat dissipation, light weight, easy to carry, flow test is convenient;
15, the instrument has a self-protection function, using a reasonable design of heat dissipation structure, and has a variety of reliable and perfect protection measures and power soft start, and a certain fault self-diagnosis and blocking function;
