The present invention relates to a safety support transformer, and more particularly, to a safety support transformer that can be easily and securely installed and secured.

In modern transmission systems, transformers are indispensable as energy converters.

A transformer is a strong electric machine used to boost alternating current (three-phase) electricity to high voltage to minimize voltage loss during long distance transportation and to step down voltage to consumers.

The main basic structure of a transformer consists of an iron core and primary and secondary coils wound around it. The transformer can step down or step up by adjusting the winding ratio of the two coils, and can increase or decrease the current.

Further, the transformer may convert the impedance when delivering the maximum power by matching the impedance. This wide range of applications makes transformers an important energy converter.

However, in general, when the transformer is installed, the primary coil and the secondary coil of the transformer are connected and fixed as they are on the PCB board. Therefore, the coil is damaged and the board is damaged due to the movement and vibration of the installed equipment. In particular, the high-voltage transformer has a big problem that the handling risks.

In addition, the conventional transformer has a method of enclosing a steel plate such as aluminum attached along the periphery on the outer circumferential surface of the thin iron core, so that the transformer itself must be fixed to the substrate and the like. There is a problem.

In addition, there is a possibility of leakage due to moisture at the contact point due to chemical changes due to deterioration of the adhesive and deterioration due to long-term use. There is a problem that the consumption.

It is an object of the present invention to provide a safety support transformer that can be easily and securely installed to solve the above problems and can be easily replaced when the transformer is relocated and replaced.

Safety supporting transformer of the present invention for achieving the above object, the first and second iron core laminated at least in the first flakes for the transformer, and the primary coil and the secondary coil wound on the first and second iron core And a clamping means for tightening and fixing the first iron core and the second iron core, respectively, wherein the primary coil and the secondary coil are placed while supporting the first and second iron cores, respectively. A fastening bolt and a fastening nut for fastening the first and second iron cores apart from the bottom plate by fastening the first and second supporting plates and the first and second supporting plates adjacent to the lower ends of the clamping means, respectively. Consists of

In this configuration, the first and second support plates are each composed of a vertical plate and a bottom plate, the vertical plate is formed with at least two fastening bolt holes, the bottom plate has at least two fixing screw holes It is preferable that it is formed.

Therefore, it can be installed only with a simple tool and can be securely supported and secured, and there is no risk, and it is easy to install and remove.

Hereinafter, with reference to the accompanying drawings for the safety support transformer of the present invention will be described in detail.

Referring to FIG. 1, the first and second iron cores 11 and 12 are upper iron cores 11a, 12a and lower iron cores 11b and 12b, respectively, which are manufactured by stacking thin iron pieces. Divided.

The upper coil cores 11a and 12a are interposed between the upper coil pedestals 16a on both sides, and the primary coil 15a is wound first, and then the secondary coil is continuously wound to complete the entire coil. Next, when the lower iron cores 11b and 12b are welded to the upper iron cores 11a and 12a via the lower coil pedestal 16b, the iron core transformer is completed. On the outer circumferential surfaces of the first and second iron cores, the clamping band 20 is surrounded along its periphery, and the clamping bolt 21 is inserted into the clamping band 20.

At this time, when the clamping bolt 21 is turned by using a tool such as a screwdriver, the thread of the clamping bolt 21 is engaged along the threaded hole 20a of the clamping band 20 so that the first and second iron cores 11, (12) are respectively tightened and fixed.

The first support plate 24 is composed of a vertical plate 24a and a bottom plate 24b and has an L shape. The second support plate 25 also consists of a vertical plate 25a and a bottom plate 25b and has an L shape.

The vertical plates 24a and 25a of the first and second supporting plates 24 and 25 have upper ends abutting the lower coil support 16b, respectively, and one side thereof has the first and second iron cores 11. ) And (12) in contact with each other to support the coil and the iron core.

As shown in FIG. 2, at least two fastening bolt holes 30 are formed in the vertical plates 24a and 25a, respectively, so that the fastening bolts 28 are fastened adjacent to the lower end of the clamping band 20. It penetrates through the bolt hole 30 and is tightened by the fastening nut 29 to fasten the first and second iron cores 11 and 12.

At this time, the heights of the vertical plates 24a and 25a are properly determined so that the first and second iron cores 11 and 12 can be spaced apart from the bottom plates 24b and 25b.

A fixing screw hole 33 is formed in the bottom plate 25b so that the transformer can be easily installed or removed by inserting the fixing screw 32 into the fixing screw hole 33 and tightening it with a suitable tool such as a screwdriver. Can be.

3 is a schematic explanatory diagram illustrating the operating principle of a transformer according to the present invention.

The operating principle of a transformer is closely related to Faraday's law of induction, which causes current to be proportional to this change when the magnetic flux in the circuit changes. Arrows in FIG. 3 indicate the change in magnetic flux.

If the change of the magnetic flux is obtained with the primary coil 15a excited by the alternating current, this fluctuating magnetic flux cuts off the secondary coil 15b, so that an induced current is obtained in the secondary coil 15b.

That is, the change in the magnetic field is mostly left in the first and second iron cores (11, 12), the transformer is operated on the principle of causing an electromagnetic induction to the secondary coil (15b).

The present invention configured as described above can be installed with only a simple tool and can be securely supported and secured. There is no risk, and it is easy to install and remove. have.

In addition, the present invention can be replaced without damaging the transformer itself has the effect of reducing the cost of damage to the transformer.
