Description

Technical Field

[0001] The utility model relates to the technical field of AC transformers, in particular to a mobile low-voltage AC transformer. Background Art

[0002] AC transformer is a type of current transformer. AC transformer is an instrument that converts large current on the primary side into small current on the secondary side for measurement based on the principle of electromagnetic induction. It usually includes a closed iron core and windings and is designed to measure AC current. AC transformers are widely used in power generation, transformation, transmission, distribution and power consumption lines. Because the current in these lines varies greatly, ranging from a few amperes to tens of thousands of amperes, AC transformers not only play the role of current conversion, but also achieve electrical isolation, thereby improving the safety of measurement.

[0003] Generally, the installation position of the AC transformer is fixed. However, when other equipment needs to be added to the measured line, if the installation position of the AC transformer affects the installation of the equipment, the AC transformer needs to be disassembled and relocated, which is very inconvenient.

[0004] In summary, the utility model solves the existing problems by designing a mobile low-voltage AC transformer. Utility Model Content

[0010] As a preferred solution of the utility model, the wire threading tube is made of hard plastic material, and the bottom of one end of the two wire threading tubes is respectively located above the two connecting bolts without touching them, and the other end of the wire threading tube extends to the edge of one side of the mounting plate where a wire threading groove is opened.

[0011] As a preferred solution of the utility model, the interior of the circular hole groove is hollow, and one end of the two connecting wires on the automatic wire reel passes through the top of the circular hole groove and comes out from the top of the mounting plate.

[0012] As a preferred solution of the utility model, the inner side of the wire threading groove is connected to the inner side of the circular hole groove, and one inner side of the wire threading groove is inclined.
