3 is a view showing the columnar transformer installation structure for the distribution line according to an embodiment of the present invention.

4 is a view showing another example of the columnar transformer installation structure for the distribution line according to an embodiment of the present invention.

The present invention relates to a column-type transformer installation hanger band for a distribution line and a structure for installing a column-type transformer for a distribution line using the same, and more specifically, a distribution line that can solve the noise problem occurring in a column-type transformer installed in a pole. The present invention relates to a hanger band for a column transformer and a structure for installing a column transformer for a distribution line using the same.

In general, a transformer is divided into a general transformer installed on the ground and a pole transformer installed on the pole. The general transformer has a structure that absorbs moisture while the transformer breathes according to load fluctuations or external temperature due to the installation of a condenser, but the columnar transformer has such a structure due to the specificity of the installation site and the relative compactness of the device. Is omitted.

These columnar transformers are fixed by hanger bands in the poles erected along the distribution lines. Since the columnar transformers are installed in the poles, they are affected by the weekly, nighttime or seasonal temperatures. Looking at the internal change of the columnar transformer due to the temperature difference, when the load is high during the day or the temperature outside during the summer rises, the insulating oil inside the transformer is affected by the temperature, the oil level rises, thereby increasing the pressure inside the transformer. The internal pressure change caused by the oil level fluctuation causes noise and vibration.

On the other hand, when looking at the external installation structure of the columnar transformer, because the hanger band is made of a metallic material, the thermal expansion and contraction is repeated but minute by the temperature difference between the day and night and the seasonal temperature difference. Since the pole is generally formed to have a smaller diameter toward the top, the contraction and expansion of the hanger band are not likely to lead to the dropout of the columnar transformer, but the small gap between the pole and the hanger band is caused by such expansion and contraction. Overshoot occurs. In particular, in recent years, since the pole is made of concrete, the micro clearance between the hanger band and the pole becomes a factor inducing noise due to the vibration of the transformer.

For this reason, the transformer installed in Jeonju causes noise in the installation state of the pole by vibration inducing factor such as wind, and this noise causes anxiety for the passengers passing under the pole. In particular, when the noise inside the transformer is combined with the noise generated between the hanger band and the concrete pole, the noise increases relatively, causing psychological anxiety for passers-by who do not know that the noise is irrelevant to the safety of the transformer. In terms of noise, the noise due to the structural problems of the transformer and the installation noise is not distinguished, so there is a difficult aspect in terms of transformer management.

Therefore, the internal noise reduction problem by improving the internal structure of the column transformer and the external induced noise reduction problem through the improvement of the structure of the column transformer have become an important issue with respect to the column transformer for distribution lines.

The present invention has been devised to solve the above problems, when installing the column transformer in the pole of the distribution line, by improving the installation structure for the distribution line that can solve the problem of external induced noise generated between the pole and the column transformer The present invention relates to a columnar transformer installation hanger band and a columnar transformer installation structure for a distribution line using the same.

In order to achieve the above object, the present invention, the outer peripheral surface of the pole around the inner circumference is fixed and coupled to the hanger bracket fixed to the columnar transformer, in the hanger band for fixing the columnar transformer to the pole, the hanger band is the outer circumferential surface of the pole It has a circular band shape surrounding the, at least one is made by combining a plurality of pieces formed to be coupled to the hanger bracket, each piece piece is formed of an arc surface in close contact with the outer peripheral surface of the pole; And bent outwardly from both ends of the band body, and formed of a coupling part provided with a bolt through hole, and fastening a coupling part of adjacent pieces of the bolt with a bolt to be firmly fixed to an electric pole, and an inner circumferential surface of the band body. A rubber band is attached to the rubber band, and the rubber band is disposed between the outer circumferential surface of the pole and the band body to provide a columnar transformer installation hanger band configured to block vibration and noise.

 In addition, the present invention in the installation structure of the columnar transformer for the distribution line is installed through the hanger band fixed to the pole, the mesh-type structure having a plurality of holes on the outer circumferential surface installed to surround the outer peripheral surface of the pole column transformer installation location Rubber bands; And a plurality of piece pieces are coupled to each other to form a circular band shape as a whole, wherein each piece piece is formed of an arc surface so as to be in close contact with the outer circumferential surface of the pole. And a hanger band formed by bending at both ends of the band body in an outward direction and having a hole through which a bolt penetrates, and a joining portion of adjacent pieces of the bolt is fastened to the pole and fixed to the pole. After the rubber band is installed, the hanger band is installed, and then the main pressure transformer fixed hanger bracket is coupled with the hanger band to install a columnar transformer on the pole, so that noise and vibration transmission between the hanger band and the pole are blocked.
