[0014] The winding is the circuit part of the transformer, which is divided into a primary winding and a secondary winding. The primary winding is connected to the power supply, and the secondary winding is connected to the load. When the alternating current passes through the primary winding, an alternating magnetic flux is generated in the core, which passes through the primary winding and the secondary winding at the same time. When the primary winding is connected to the alternating power supply, the current generates an alternating magnetic flux in the core. This alternating magnetic flux passes through the primary winding and the secondary winding at the same time. According to the law of electromagnetic induction, when the magnetic flux passes through the secondary winding, an induced electromotive force is generated in the secondary winding. The size of the induced electromotive force is proportional to the rate of change of the magnetic flux, that is, proportional to the rate of change of the current in the primary winding. Because the number of turns of the primary winding and the secondary winding is different, the induced electromotive force in the secondary winding (i.e., the output voltage) is different from the voltage in the primary winding.

[0033] like Figures 1-4 As shown, this transformer, which is easy to disassemble and maintain, includes a core sealing plate 1 and a winding 2, with the winding 2 arranged between the core sealing plates 1.

[0034] The top and bottom edges of the iron core sealing plate 1 are fixedly connected to positioning combs 3, which are composed of several comb teeth;

The positioning pin 9 is inserted into the connector 8, and the positioning pin 9 is threaded with a fastener 10. The fastener 10 is tightened on the surface of the connector 8.

[0039] In the embodiment 1, two iron core sealing plates 1 are symmetrically arranged, and the winding 2 is wound on the iron core connected between the two iron core sealing plates 1. The two sides of the positioning comb 3 are attached to the corresponding heat sinks 5, and the end of the positioning comb 3 abuts against the inner side of the outer plate 4. The positioning comb 3 not only plays a role of positioning and supporting the heat sinks 5, but also optimizes the heat conduction path between the heat sinks 5 and the iron core sealing plate 1 through the structure. By means of the close cooperation of the positioning comb 3 and the heat sink 5, strong positioning of each component of the transformer is realized, and the stability and accuracy in the assembly process are ensured.

[0040] In the embodiment 2, the vertical end surface of the heat sink 5 abuts against the outer side of the iron core sealing plate 1, and the base 6 is welded with the outer plate 4.

[0042] The transformer is mainly a single-phase transformer, and the main body is composed of an iron core sealing plate 1, a winding 2, an outer plate 4, a heat sink 5, a base 6, and a foot 7 structure,

[0043] The winding 2 is the circuit part of the transformer and is divided into a primary winding and a secondary winding. The primary winding is connected with the power supply, and the secondary winding is connected with the load. When the alternating current passes through the primary winding, the alternating magnetic flux is generated in the iron core, and the magnetic flux passes through the primary winding and the secondary winding at the same time. When the primary winding is connected with the alternating power supply, the alternating magnetic flux is generated in the iron core. The alternating magnetic flux passes through the primary winding and the secondary winding at the same time. According to the electromagnetic induction law, when the magnetic flux passes through the secondary winding, the induced electromotive force is generated in the secondary winding. The size of the induced electromotive force is proportional to the rate of change of the magnetic flux, that is, proportional to the rate of change of the current in the primary winding. Since the number of turns of the primary winding and the secondary winding is different, the induced electromotive force (i.e. the output voltage) in the secondary winding is different from the voltage in the primary winding. By adjusting the turn ratio, the voltage can be increased or decreased.

[0044] When the transformer is disassembled, the foot 7 is first removed, the fastener 10 is removed, and then the outer plate 4 and the heat sink 5 are separated outward, which is beneficial to the maintenance of the iron core sealing plate 1, the inner side iron core, and the winding 2, and the operation is simple and convenient.
