Claim:
1. A system for examining transformers full-automatically, comprising: a material conveying line, a material charging device, an examination conveying line, an appearance inspection device, an insulation test device, an error examining device, a laser marking device, a material discharging device, and an examination management system; wherein the insulation test device, the error examining device, and the laser marking device are sequentially arranged along a direction of advance of the examination conveying line; the material conveying line is adapted to deliver turnover boxes loaded with transformers to be examined from a storage system to a material charging station, and deliver turnover boxes loaded with transformers having been examined located at a material discharging station back to the storage system; the material charging device, located beside the material charging station of the material conveying line, is adapted to move transformers located at the material charging station on the material conveying line to the examination conveying line; the examination conveying line is adapted to move transformers to stations corresponding to respective devices; the insulation test device is adapted to detect insulation resistances, test power frequency withstand voltages and test inter-turn insulations of transformers; the error examining device is adapted to detect basic errors and magnetic saturation margins of transformers; the laser marking device is adapted to imprint identification information on qualified transformers; the material discharging device, located beside the material discharging station on the material conveying line, is adapted to transfer transformers having been examined from the examination conveying line to the material conveying line; and the examination management system is adapted to control coordinate operation of respective devices, the material conveying line and the examination conveying line and to sort transformers accurately according to feedback information from the insulation test device and the error examining device.
