Description

Technical Field

[0001] The utility model relates to the technical field of electronic components, in particular to a transformer coil and a transformer. Background Art

[0002] Transformers and transformer coils are vital components in power systems. A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. It is mainly composed of a primary coil, an iron core, and a secondary coil.

[0003] The outer surface of the transformer is covered with a protective shell, which is usually used to protect the transformer from damage by the external environment and provide a certain degree of electrical isolation. However, the existing protective shell design is too complicated and includes multiple fasteners and connectors, which makes disassembly too laborious, prolongs the transformer maintenance time, and affects the reliability and stability of power supply. In addition, when the coil is wound around the iron core, the direct contact between the two will cause wear on the coil, affecting the service life of the coil, which has limitations.

[0004] The protective shell is usually composed of multiple parts, which are connected to each other by a large number of fasteners such as bolts, nuts, and buckles. When the transformer needs to be repaired or the internal components need to be replaced, the maintenance personnel need to remove these fasteners one by one. This process is not only laborious and time-consuming, but also easy to cause the fasteners to be damaged or lost due to improper operation, further extending the maintenance time. In addition, the coil is in direct contact with the iron core, which will not only reduce the insulation performance of the coil, but also may cause safety hazards such as short circuits. At the same time, wear and tear will also accelerate the aging process of the coil, shorten its service life, and increase the frequency and cost of replacing the coil. In view of the above situation, the utility model provides a transformer coil and a transformer to solve the above problems. Utility Model Content

A fixing groove 36 is formed inside the second protective shell 312 , and the clamping block 33 is movably clamped inside the fixing groove 36 .

[0025] In this embodiment, when the protective shell 31 needs to be removed, the paddle plate 35 is grasped and pushed inwardly so that the block 33 is disengaged from the inside of the fixing groove 36.
