Description

Technical Field

[0001] The utility model relates to the field of box-type substation protection equipment, in particular to a box-type substation anti-smashing structure suitable for American box-type substations in the field of new energy wind power. Background Art

[0002] With the development of the new energy wind power industry, more and more box-type substations are put into use. Box-type substations are mostly distributed in the wilderness, and the quality and environmental adaptability of box-type substations are gradually improved. Box-type substations are generally installed with the wind turbine tower and will be installed under the wind turbine tower. In winter, when the temperature is low, the fan impeller will freeze. As the impeller rotates, ice will fall to the top of the box-type substation, causing damage to the top cover. In particular, the American box-type substations are exposed outside the box-type substation. Because the materials used for the sheets are thin and weak in strength to meet the heat dissipation requirements, they are easily impacted by large ice blocks and cause oil leakage, affecting the safe operation of the box-type substation. By setting an anti-smashing structure on the top of the American box-type substation, it is helpful to buffer the impact of large falling ice blocks on the box-type substation, prevent damage to the box-type substation, and ensure the safe operation of the box-type substation. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a box-type substation anti-smashing structure with reasonable structural design, which can effectively improve the top protection capability of the American box-type substation without affecting the heat dissipation.

[0005] The invention discloses a box-type substation anti-smashing structure, which comprises columns, ring beams, angle steels and pull plates. There are six columns in total, one column I at the front and rear of the middle of the box-type substation, four columns II at the four corners of the box-type substation, a fixing plate I welded to the bottom of the column, the fixing plate I is fixedly connected to the box-type substation base, the box-type substation base is also fixedly connected to the fixing plate II, the upper end of the pull plate is fixedly connected to the column I, and the lower end is fixedly connected to the fixing plate II, the top of the column is fixedly connected to the ring beam by bolts, the upper end of the ring beam is arranged with angle steels, the angle steels are arranged at equal distances and cover the top of the box-type substation, the right angles of the angle steels face upwards, and the lower ends are fixedly connected to the ring beam.

[0006] The pull plate, column I and base form a triangular support structure to enhance the stability of the entire anti-smash structure.

[0007] The columns are made of 8# channel steel, and the columns II on both sides of the box-type transformer base can also be reinforced by pulling plates.

[0008] The column I is directly fixedly connected to the ring beam, and the column II is fixedly connected to the ring beam by a right-angle support beam.

[0009] Furthermore, the ring beam is made of 8# channel steel, and a 5# angle steel is welded every 50-100mm on the upper part of the ring beam. The angle steel should completely cover the entire box-type transformer.

[0015] The utility model is described in detail below with reference to the accompanying drawings:

[0016] As attached Figure 1 , 2 The illustrated box-type substation anti-smashing structure comprises columns, a ring beam 2, angle steels 3, and a pull plate 6. There are six columns in total, with a column Ⅰ11 at the front and rear of the middle of the box-type transformer, and four columns Ⅱ12 at the four corners of the box-type transformer. A fixing plate Ⅰ4 is welded to the bottom of the column, and the fixing plate Ⅰ4 is fixedly connected to the box-type transformer base 5. The box-type transformer base 5 is also fixedly connected to a fixing plate Ⅱ7. The upper end of the pull plate 6 is fixedly connected to the column Ⅰ11, and the lower end is fixedly connected to the fixing plate Ⅱ7. The top of the column is fixedly connected to the ring beam 2 by bolts. Angle steels 3 are arranged at the upper end of the ring beam 2. The angle steels 3 are arranged at equal distances and cover the top of the box-type transformer. The right angle of the angle steel 3 faces upward, and the lower end is fixedly connected to the ring beam. The setting of the angle of the angle steel is conducive to enhancing the strength of the entire top cover structure, and at the same time is conducive to breaking larger ice blocks that fall down, thereby improving the protection capability of the top cover.

[0017] The pull plate, column I and base form a triangular support structure to enhance the stability of the entire anti-smash structure.

[0018] The columns are made of 8# channel steel, and the columns II on both sides of the box-type transformer base can also be reinforced by pulling plates.

[0019] The column I is directly fixedly connected to the ring beam, and the column II is fixedly connected to the ring beam by a right-angle support beam.

[0020] Furthermore, the ring beam is made of 8# channel steel, and a 5# angle steel is welded on the upper part of the ring beam every 50-100mm. The angle steel should completely cover the entire box-type transformer. The setting of this gap can fully ensure the heat dissipation and ventilation capacity of the top, and at the same time can withstand the impact of ice cubes. For example, the ice cubes condensed on the fan impeller mentioned in the background technology are relatively large in size, and this gap setting can completely block such falling ice cubes.

[0021] The box-type transformer base is provided with a mounting hole or a shipping hole for connecting the fixing plate I or the fixing plate II.

[0022] After the American-type box-type transformer is installed with this anti-smashing structure, it can effectively prevent large ice blocks from falling while ensuring heat dissipation, protect the internal electrical equipment and fragments of the box-type transformer from damage, ensure the safe operation of the box-type transformer, reduce the wear and failure of the box-type transformer caused by being smashed, and help extend the service life of the box-type transformer.

[0023] The present invention is not limited to the above-mentioned embodiments. On the basis of the technical solution disclosed in the present invention, technicians in this field can make some substitutions and deformations to some technical features therein according to the disclosed technical content without creative labor, and these substitutions and deformations are all within the protection scope of the present invention.
