Design of Protection Functions Test System for Intelligent Low Voltage Electrical Apparatus Based on Flexible Test Technology

Abstract:

In order to satisfy the needs of protection functions test for intelligent low voltage electrical apparatus, based on the introduction of features of the flexible test technology, a design of protection functions test system for intelligent low voltage electrical apparatus based on the flexible test technology was proposed in this paper. The test system was made up of the hardware composed of industrial computer, multifunction data acquisition card, three phase current generator, three phase voltage generator, etc, and the software developed by LabVIEW. The design idea and the test flow of the software were also introduced in detail. Finally, the application example shows that the protection functions for intelligent low voltage electrical apparatus constructed based on flexible test technology could carry out a high efficient, automatic, accurate test, which fully reflected the three characteristics of the flexible test technology ——flexibility, adaptability and expandability. Therefore, the test system has great practical value and application prospect.
