Describe：The microcomputer-based relay protection calibrator is based on the "Technical Conditions of Microcomputer-based Rela

The microcomputer-based relay protection calibrator is based on the "Technical Conditions of Microcomputer-based Relay Protection Test Device (Discussion Draft)" issued by the Ministry of Electric Power, and extensively listens to users’ opinions, summarizes the current advantages and disadvantages of similar domestic products, and makes full use of modern A new type of miniaturized microcomputer relay protection tester realized by advanced microelectronics technology and devices. It adopts a stand-alone independent operation, and can also be connected to the advanced structure of a notebook computer. The host has a built-in new generation high-speed digital signal processor microcomputer, a true 16-bit DAC module, a new modular high-fidelity high-power amplifier, a large-screen LCD display and a flexible and convenient rotating mouse controller. Stand-alone operation already has a strong function, which can be used for most tests, and it has more powerful operation functions if it is connected to a computer. Small size and high precision. It not only has the superior performance and advanced functions of the large-scale tester, but also has the advantages of small size and flexibility, simple operation, high reliability, etc., and the cost performance is high. It is a handy tool for relay protection workers.

Standard 4-phase voltage and 3-phase current output. With 4-phase voltage and 3-phase current output, it is convenient to carry out various combination outputs for various types of protection tests. The single-phase voltage can output up to 120V, the single-phase current can output up to 40A (10 seconds), the current three can output 120A, the fourth phase voltage Ux is a multi-function voltage item, which can be set to 4 kinds of 3U0 or check the same voltage, or Output at any certain voltage value.

Single machine is easy to operate Single machine is operated by a convenient and flexible rotating mouse through the large-screen LCD display, all displayed in Chinese. It can complete most of the field test and verification work, can verify various relays and microcomputer protections, and can simulate various complex transient, permanent, and transitional faults for a whole set of tests. It can be used after booting, and the operation is convenient and quick.

Dual operation mode, connected to the computer and running through a full set of Chinese operating software on the Windows platform, can perform various large-scale, complex and more automated calibration tasks, can easily test and scan various protection settings, and can store and test in real time Data, display vector diagrams, draw fault waveforms, print reports online, etc.

The software is powerful and can complete various large-scale and complex calibration tasks with high degree of automation, such as three-phase differential test, factory power quick-cutting, automatic switching test, line protection inspection and simultaneous reclosure, etc. It can easily test and scan various Protect the fixed value, perform fault playback, store test data in real time, display vector diagrams, print reports online, etc.

Rich switch contacts RCJB-331 has 7-way contact input and 2 pairs of empty contact output. The input contacts are empty contacts and compatible with 0～250V potential contacts, which can be intelligently and automatically identified. The input and output contacts can be expanded according to user needs.

Large-screen LCD display This machine uses a 320×240 dot-matrix 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.

Self-protection It adopts a reasonably designed heat dissipation structure, and has a variety of reliable and complete protection measures and soft start of the power supply, as well as certain fault self-diagnosis and blocking functions.

With independent dedicated DC power output The device is equipped with a 110V and 220V dedicated DC power output.

High cost performance It is a cross-professional joint design product that integrates advanced scientific and technological achievements from multiple disciplines. It combines the performance of a large-scale tester and the price of a small-scale tester, and has a high performance-to-price ratio.
