Six phase microcomputer relay protection tester/relay protection calibration system test equipment
In addition to calibrating all kinds of relays (such as current, voltage, inverse time, power direction, impedance, differential, low cycle, synchronous, frequency, DC, intermediate, time, etc.) and microcomputer protection, it can simulate transient, permanent, transformational faults from single phase to three phase for whole group tests. It can also complete a variety of large-scale and complex calibration work with high degree of automation, can automatically test and scan various protection values, fault playback, test backup self-casting, fast cutting, system oscillation, etc., real-time storage of test data, display vector graphics, online printing reports, etc. The 6-phase current is convenient for three-phase differential protection testing, and the 12-phase output can be used for self-propelled testing.

Technical characteristics
Standard 12-phase voltage and current complete simultaneous output, and amplitude, phase, frequency separately adjusted.
12-channel closed-loop recovery wave monitoring Mining, monitoring and recording of the 12-channel voltage and current output waveform of the machine, which can intuitively and conveniently monitor and observe the distortion of the output waveform. The recording time is determined by the capacity of the hard disk, and the recorded wave file can be replayed in fault reproduction.
Dual operation mode In addition to stand-alone operation, the device can also be connected to an external desktop or laptop computer for operation, the two ways of function is consistent, truly complete dual operation mode.
The output part of the high-performance main controller adopts ultra-high-speed DSP+FPGA control, strong real-time signal processing capability, wide transmission frequency band, high precision waveform of 2400 points per week output, 18-bit DA converter. The output waveform precision is high, the distortion is small, the linearity is good.
High-speed large capacity industrial computer, 10.4 "large screen built-in embedded Windows XPE operating system, software system is highly stable, electronic hard disk capacity is large. The device comes with 10.4 "large screen, large display capacity and font, good effect.
The modular component structure adopts military technology to realize multi-level insulation isolation and equipotential electrostatic shielding protection. A large number of precision components are used, and professional structural design is carried out. The device has high reliability, good EMC performance, small size, light weight, full function and easy to carry.
The output end of the new high-fidelity linear power amplifier has always adhered to the high-fidelity and high-reliability modular linear power amplifier, rather than the switching type power amplifier, with high precision of small signals and exquisite and smooth waveform. It will not cause medium and high frequency interference to the test site, and ensure smooth waveform and excellent precision from large current to small current.
Powerful function can complete a variety of large and complex calibration work with high degree of automation, can easily test and scan a variety of protection set values, fault playback, real-time storage of test data, display vector graphics, online printing reports, etc. The 6-phase current is convenient for three-phase differential protection testing, and the 12-phase output can be used for self-propelled testing.
Automatic test and quick cutting function 10 open in 8 open out, can test a variety of automatic and quick cutting devices. The test interface design is beautiful, which can directly display the main wiring diagram of various systems, the status of each switch contact, the current and voltage amplitude. It is very intuitive and convenient to test, record and display the operation process of the standby automatic transmission device.
The contact provides 10 contact inputs and 8 air contact outputs. Input contacts are null contacts and 0~250V potential contacts compatible, intelligent automatic recognition. Input/output contacts can be expanded according to user needs.
Independent adjustable DC power supply with a high power 110V or 220V dedicated DC power output.
Interface complete device panel has its own keyboard and mouse, single machine can perform complete operation. The device is equipped with USB port and network port, which can communicate with PC for operation, and can be connected with external printer, keyboard, mouse, U disk, etc.
The built-in GPS device has its own GPS interface, which can realize dual synchronous testing, and can carry out optical fiber longitudinal differential protection test.
Perfect self-protection function Heat dissipation structure design is reasonable, hardware protection measures are reliable and perfect, with power soft start function, software for fault self-diagnosis and output lock and other functions.
Light and small high-integration single machine and integrated structure belong to cross-professional joint design products, integrating many scientific and technological achievements. Small size, light weight, with a high performance-price ratio.
