Abstract
The AC voltage test is an important means to effectively detect the insulation defects of the equipment. The problems of low efficiency, poor safety, and poor compatibility of the AC voltage test for smart electricity meters and data acquire terminal of the special transformer, the fully automatic AC voltage test device are studied and designed by software programming, PLC control technology, and automatic crimping technology. The automatic test and result judgment of the AC voltage test for the smart electricity meters and data acquire terminal of the special transformer are realised, which makes many problems of the existing test equipment to be effectively solved. Thus, the efficiency, compatibility, safety and reliability of the test are improved.
