Nan Ruixi high NRJB-802 relay protection tester factory wholesale prices

Setting relay fault analysis and simulation application management system in order to deepen understanding relay fault analysis setting management and simulation systems, one should first understand relay fault analysis setting application management and simulation systems, the author of practical work experience This was related to the application summary. 3.1 Relay Fault Analysis and Simulation setting management system brings convenience relay fault analysis setting management and simulation system for the production of work has brought a lot of convenience, mainly in the following aspects of production. It can automatically generate one main grid maps, as well as protection sequence impedance network configuration diagram, this function to increase the efficiency of production work; secondly it allows manual tuning and auto-tuning a reality, complete-tuning work After also can play tuning book, so you can bring the whole set with the set value, greatly reducing the human factor caused the error situation; thirdly it can be the fault simulation function tests Protection Action; Fourth it can according to the actual grid Data specific trouble spots quickly check the grid, to provide accurate data for the development and favorable subsequent work; its five short-circuit calculation process can set a variety of operation modes and can also simulate multiple types of failure, failure to provide more analysis of Multi-data basis; its six powerful query the system management, search functions provide a variety of operating convenience. Introduction NRJB-802 relay protection tester (three phase accuracy of 0.5, IPC) is a reference to the basis of "microprocessor-based relay test equipment technology," issued by the Ministry of DL / T624-1997, the widely listen to the views of users, summarizes the advantages and disadvantages domestic similar products, make full use of modern technology and advanced microelectronics devices to achieve a new type of small computer relay tester. The relay protection tester using single run independently, advanced structure also join the laptop to run. Instrument host using DSP + FPGA structure, true 16-bit DAC output, built new modular high-fidelity linear power amplifier, comes 8.4 inch 800 × 600 resolution TFT color display and high-grade industrial keyboard and mouse. WindowsXP operating system, and powerful. Small size, high accuracy. Both with large tester superior performance, advanced features, but also has a small tester compact and flexible, simple operation, high reliability, high cost performance. It is a good tool to protect workers following handy. Host Host Host Host Another name on the back of the control panel relay protection tester, computer following the security instrument, relay tester, three-phase relay tester, following the security tester, three successive security tester, three-phase relay school test instrument, following the security calibrator, three successive insurance calibrator, following the security instrument Features 1, to meet the scene all test requirements. The four-phase voltage relay protection tester with a standard, three-phase current output, voltage 125V / phase, current 40A / phase. Three-phase shunt up to 120A. A variety of both traditional relays and protective devices were tested, but also on a variety of computer protection modern subjected to various tests, especially for transformer differential protection and backup power automatic switch device, the test is more convenient and perfect; 2, various Technical indicators issued by the Ministry fully meet DL / T624-1997 "microprocessor-based relay test equipment and technical conditions" standard; Nanrui Xi High Electric Industrial Co., Ltd. www.nrxgsy.com the national grid designated brands 3, Classic WindowsXP operating interface, friendly interface, easy operation; high-performance embedded industrial control computer and the 8.4-inch 800 × 600 resolution TFT color display provides rich visual information, including current working status and all kind of help information; 4, the machine comes with Windows XP system restore function, to avoid system shutdown or caused by an illegal misuse collapse; 5, equipped with ultra-thin industrial keyboard and optical mouse, you can operate like an ordinary PC, the same complete a variety of operations by the keyboard or mouse; 6, the main control board with DSP + FPGA architecture, 16-bit DAC output to the fundamental point can produce weekly 2000 high-density sine wave, greatly improved the quality of waveform improve test precision instrument; 7, high fidelity amplifier using linear amplifier, both to ensure the accuracy of small current, but also to ensure the stability of a large current; 8, the use of USB direct interface and PC communications, without any adapter cable, easy to use; 9, It can be connected to a laptop (optional) operation. Notebook computers and industrial computer using the same set of software, without re-learning methods of operation; 10, with separate dedicated DC auxiliary voltage source output, the output voltages are 110V (1A), 220V (0.6A). Required to provide to the DC operating power relays or protective device; 11, with software-calibrating function, avoiding the need to open the case by adjusting potentiometer to calibrate the accuracy, thus greatly improving the stability of accuracy.
