Design of Automatic Test System for Intelligent Motor Protector

Based on the digital electronic technology, analog electronic circuit, single chip microcomputer and host computer language, an automatic test system was designed to ensure high precision and reliability of intelligent motor protector. The system hardware and software design were introduced. The test results show that the system can automatically signalize intelligent motor protector to test its precision, function of protection and extra performance. In addition, it can automatically differentiate whether test results satisfy the technical requirements as well as check whether test data can be automatically saved and printed after testing. Compared with conventional manual-test systems, it has many advantages such as high measurement efficiency, specification of testing procedure, high automatic level, high accuracy ,good generalization, more convenience and less expense of test data management and so on. It was proved that the system is practicable in the assembly line.
