Wuhan relay test device manufacturers - Wuhan relay test manual Wuhan relay tester is on the basis of reference issued by the Ministry of Electric Power microprocessor-based relay test equipment technical conditions (draft) ", widely listen to the views of users, summarizes the advantages and disadvantages of the domestic like product, make full use of modern, state-of-the-art microelectronics technology and devices to achieve a new type of small relay protection tester. It uses a stand-alone run independently, can join the laptop running advanced structure. Host built a new generation of high-speed digital signal processor computer, true 16-bit DAC module, the new modular high-fidelity power amplifier, comes with a large LCD display and flexible rotation of the mouse controller. Single independent operator already has a strong function can be carried out most of the trials, connecting the computer to run more powerful operating. Small size, high accuracy. The Wuhan relay tester, English name: Relayprotectiontester,. The host using the high-speed high-performance digital signal processor computing speed, transmission frequency bandwidth, high-density fitting can generate 360 ??points per cycle on the fundamental sine wave. This is the highest level of similar output mode. High fidelity waveform distortion, especially when the harmonic output, even if the sixth harmonic, 300Hz also can achieve a high density of 60 points per cycle D / A. Wuhan relay tester - Overview: relay protection tester is a new type of intelligent test equipment, relay test tools with the regulator and phase shifters combination, bulky and accuracy is not , can not meet the modern relay protection check. With the continuous development of science and technology, microcomputer relay protection has been widely used in circuit protection, the main transformer protection, excitation control and other fields, has become a mainstream integrated substation automation. The application of the relay tester relay tester (relay test set, following Paul) English name: RXRelayTester the relay microprocessor-based test device to ensure safe and reliable operation of the power system is an important testing tool. With the rapid development of computer technology, microelectronic technology, power electronics technology, applying the latest technological achievements continue to introduce new high-performance relay test device is the inevitable trend of technological progress. Wuhan relay tester - How it works: relay test equipment two loops of the primary circuit and the secondary circuit, main circuit using the large knob to adjust the auxiliary circuit using small knob to adjust the main circuit panel output selection " button switch to control the amount of various outputs, and switching an output on the digital voltage / ammeter can automatically monitor its output value. Auxiliary circuit is controlled by the output switch directly regulate the output measurement can be attached outside the multimeter to measure. Main circuit schematic of the relay test equipment: input AC220V power by the insurer by the output control relay K1 into double brushless regulator T1 input terminal T1 large knob to adjust the power to enter the isolation transformer T2 (part-time up-flow) or The stream is divided into three tap output a tap for AC0-
