Microcomputer relay protection tester performance characteristics and technical indicators
Microcomputer relay protection tester performance characteristics and technical indicators It is used for setting and testing the parameters of various relay protection devices in power plants and substations, with high intelligence and accurate testing. It can simulate 12-channel current and voltage amplitude modulation, phase shifting, phase-separated independent frequency conversion, multi-state fault simulation, superimposed harmonics, with distortion alarm, recording data playback output, etc., to ensure the safe operation of power plants, substations and lines. Important test instrument. I will find you a picture. The test software adopts Windows interface, complete functions and friendly interface. It can complete all kinds of relay protection devices, automatically generate test database and test report. It is easy to use and is a power plant, power supply bureau, research institute, and related enterprise. Equal unit ideal relay protection test device. BY903 microcomputer relay protection tester product features The microcomputer relay protection test system adopts a number of high-tech technologies including advanced digital signal processing technology and communication technology, which reflects the new trend of integration and integration. The main features are as follows: a. Built-in high-performance industrial computer, using embedded industrial system Windows, its simple system core has stable, reliable and efficient hardware real-time performance, integrated and integrated, and can easily complete various complicated test functions without external computer. It can also prevent computer virus infringement, even if you delete files by mistake, it will not damage the operating system and ensure system security. b. Original dynamic tracking technology, using high-performance DSP, FPGA, 24-bit DA and high-precision linear power amplifier technology, output high-precision waveform of 1600 points per week, can quickly and accurately control the response analog output power system fault model various transients The changing transient waveform enables the full-scale analog output, from DC to 1 kHz, to fully guarantee the instantaneous variation characteristics and high precision, which is of special significance for the accuracy of the ultra-high voltage relay protection test work. c. The user-friendly interface design provides a familiar and familiar Windows interface with built-in touchpad and keyboard. It is easy to operate like a laptop. The built-in USB interface can be used to upgrade software and exchange data or external mouse. , keyboard operation. You can also work with an external laptop through the network port. d. The new test software is based on Windows system, using embedded software development tools, full-featured, user-friendly, easy to use, excellent underlying hardware control performance, the first test template database organization of multi-layer tree structure, flexible OFFICE file format The test report provides a data foundation for the integration and systemization of the test database and test report management. e. It has a special test simulation function with characteristics, concise and convenient, and various practical and effective relay verification procedures. It also has a set of microcomputer protection and automatic test procedures for automatic check devices. The fault-like simulation program can realistically simulate and replay various types of faults, transients, oscillations, and reclosing behaviors on site. f. 6-phase voltage and 6-phase current can be simultaneously output without changing any soft and hard parts. The amplitude, phase, frequency and DC component of each phase can be independently changed and adjusted at the same time. The constant frequency conversion of 1600 points per week, no phase shift and sudden change, makes the low cycle load shedding test accurate and reliable; the opening channel is independent and non-polar, and can automatically adapt to various active passive contacts. g. Advanced high-precision linear power amplifier technology has comprehensively improved the power amplifier system of the device, and has various fault detection and protection functions such as anti-misoperation, short circuit, external electric shock and temperature overrun, ensuring stable and reliable continuous operation of the device. . It has 110V/220V±10% independent auxiliary DC power supply. The open channel is independent and non-polar, and can automatically adapt to various active and passive contacts. Modular design of the whole machine, a large number of optimized design and process improvement, more compact, lighter, easy to operate, easy to maintain. respected user: Thank you for your interest in our products, in addition to the company beyond this catalog, as well as AC and DC voltage divider or converter, dielectric loss tester, transformer volt-ampere characteristic tester and so on, if your products to our Interested in consulting.
