Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to an adjustable large transformer iron core shielding ring. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are a primary coil, a secondary coil and an iron core (magnetic core). Its main functions include voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. At present, the length of the traditional large transformer core shielding ring is often fixed and cannot be adjusted according to actual usage, thereby reducing the scope of application. For this reason, we propose an adjustable large transformer core shielding ring to solve the problems raised in the above background technology. Utility Model Content

[0005] Furthermore, a transmission cavity is opened inside the main shielding ring and corresponds to the position between the two receiving grooves. A rotating seat is provided on the left side of the inner wall of the main shielding ring. One end of the rotating seat passes through the transmission cavity and is fixedly connected to a driving bevel gear. A rolling bearing is fixedly installed inside the main shielding ring at a position corresponding to the transmission cavity and the receiving groove. A screw is rotatably connected in the rolling bearing. One end of the screw passes through the transmission cavity and is fixedly connected to a driven bevel gear used in conjunction with the driving bevel gear, and the other end passes through the receiving groove and extends to the inside of the telescopic shielding ring.

[0006] Furthermore, a positioning screw is provided at a position corresponding to the receiving groove on the right side of the inner wall of the main shielding ring, and one end of the positioning screw penetrates into the interior of the telescopic shielding ring and is fixedly connected thereto.

[0007] Furthermore, a plurality of positioning holes adapted to the positioning screw are provided at equal distances on the right side of the inner wall of the telescopic shielding ring corresponding to the position of the positioning screw, and the positioning screw is threadedly connected to the main shielding ring.

[0008] Furthermore, screw holes for use with the screw rods are provided at opposite ends of the two telescopic shielding rings and at positions corresponding to the screw rods.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] When the length of the shielding ring needs to be telescopically adjusted, the rotating seat can be rotated, so that the active bevel gear drives the two driven bevel gears to rotate, and then drives the screw to rotate under the connection of the rolling bearing, and the telescopic shielding ring can be retracted and moved in the receiving groove through the threaded connection with the screw hole. After the adjustment is completed, the positioning screw is rotated and its end is screwed into the corresponding positioning hole to form a fixed shape and can be used. The adjustable large transformer iron core shielding ring has a reasonable structural design and is easy to use. It adopts an adjustable telescopic design, and the length of the iron core shielding ring can be quickly adjusted according to actual use conditions, thereby increasing the scope of application, having high practicality, and fully meeting the use needs of the transformer.
