[Abstract]:With the rapid development of the market economy, the demand for electric energy is increasing and the dependence becomes stronger. The low voltage electrical apparatus plays an important role in the transmission and distribution of electric energy and the task of protecting and controlling the electrical equipment. A kind of important equipment to reduce the energy consumption of the line and improve the voltage quality of the power grid is of great significance to realize the saving society. The continuous development of the new products of the low voltage complete reactive power compensation device requires more advanced testing and analysis equipment to adapt to its development to meet the requirements of various aspects of performance testing and the discharge test. It is said that the testing device can achieve instantaneous and real-time data acquisition function, with automatic analysis and calculation of parameter testing. The test results can automatically generate reports, and make the test equipment small and convenient to move, so that the detection efficiency of the field capacitance discharge test is greatly improved, and the traditional detection device has not been used. In order to solve the above problems, this design uses voltage sensor, data acquisition card, PC, and virtual instrument to develop a set of portable reactive power compensation device discharge tester in order to solve the above problems, and use LabVIEW to develop the upper computer software to realize the low voltage reactive power compensation device. When the capacitor discharge test is carried out, the electrical parameters are automatically collected, processed, and analyzed and calculated. The software program is tested on the test site, and the hardware part is combined to form a complete set of testing equipment, and the self calibration and measurement uncertainty analysis of the instrument is carried out. At the same time, the author's experience in practice is based on the experience of the author. And experience, on the basis of not violating the national standard, the process of the test is further optimized to make it more operational. This article describes in detail the following aspects: the development of the low voltage reactive power compensation device and the status of its performance detection; the design and implementation of the hardware and software of the capacitance discharge test instrument; The test results show that the portable capacitance discharge test instrument designed in this paper can quickly complete the performance test of the discharge test of the low voltage reactive power compensation device on the basis of meeting the requirements of the national standard on the capacitance discharge test, and improve the working efficiency. The test burden is greatly relieved and the effect is achieved. The software interface developed by LabVIEW has the advantages of friendly reading, high precision, good stability, good application value and development prospect.
