Description

Technical Field

[0001] The utility model relates to an automatic testing device for a semi-finished sealed transformer, in particular to an automatic testing device for a semi-finished sealed transformer with a compact structure, which can directly perform electrical performance testing after argon welding and has high working efficiency. Background Art

[0002] Transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. Transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). In electrical equipment and wireless circuits, it is often used to increase or decrease voltage, match impedance, and isolate safely. In the generator, whether the coil moves through the magnetic field or the magnetic field moves through the fixed coil, the potential can be induced in the coil. In both cases, the value of the magnetic flux remains unchanged, but the amount of magnetic flux interlinked with the coil changes. This is the principle of mutual induction. Transformer is a device that uses electromagnetic mutual induction to transform voltage, current and impedance. After the sealed transformer is argon welded, the electrical performance test is not carried out. The performance test is carried out only after the outer cover is directly installed and glued to the finished product section. In view of the above reasons, it is necessary to provide a semi-finished automatic testing device for sealed transformers that simplifies the process and improves work efficiency.
