Transformer

Abstract

The invention discloses a transformer which comprises an iron core element. The iron core element comprises a plurality of parallel flat stacked pieces which are adjacently stacked. The stacked pieces include E-shaped stacked pieces and second stacked pieces, wherein the E stacked pieces and the second stacked pieces form 'B' shapes, the contact parts of the E stacked pieces and the second stacked pieces are provided with meshed teeth, and antiskid layers provided with holes are disposed among the stacked pieces. The transformer has the advantages that the iron core element is stable in structure and less prone to stacked piece displacement, and power reduction and coil heating and burning during use are avoided.

Description

[0001] technical field [0002] The invention relates to a transformer. Background technique [0003] The transformer uses the principle of mutual inductance to change the AC voltage and consists of a primary coil, a secondary coil and an iron core. The structure of the existing transformer core includes a plurality of laminations, and the laminations include lamination elements with sections "I" and "E", and the I laminations and the E laminations form a "day"-shaped lamination. The center arm of the E-stack is located in the center of the spool 1. Since the laminations are stacked one by one, that is, after the I laminations of the first layer and the E laminations are butted, the laminations of the second layer are assembled on the core element in the opposite direction, that is, the upper and lower adjacent laminations of the I laminations are all E stack. However, this structure will have problems during use, that is, it is necessary to ensure that the positions of ...

Problems solved by technology

However, this structure will have problems during use, that is, it is necessary to ensure that the positions of the I stack and the E stack are fixed. Since the I stack and the E stack are in contact, it is prone to problems, that is, the I stack and the E stack are in contact with each other. The position of the laminations is prone to shift, which makes the contact between the two poor. Similar to the reduction of the iron core, the reactance is reduced, and the power is also reduced. In severe cases, the coil may even heat up or burn out.
