Technology Field

[0001] The present invention relates to a direction-changing hanger band structure for a multi-type transformer, and more specifically, to a direction-changing hanger band structure for a multi-type transformer that can be used for both the upper and lower sections, so that when installing pole-mounted transformers of the same or different capacities with a difference in lower height, installation can be easily achieved by simply changing the direction. Background Technology

[0002] Generally, transformers are classified into ground transformers installed on the ground and pole transformers installed on utility poles.

Multiple pole-mounted transformers with different capacities of 10kva, 20kva, 30kva, 50kva, 75kva, and 100kva are installed on the utility poles with different heights so that power supplied from the power source can be reduced to an appropriate voltage and supplied to the power user.

[0004] As shown in FIGS. 1 to 3, a plurality of pole-mounted transformers (10a) (10b) are supported and fixed to a pole (30) by means of a fastening member (22) of a bolt and nut, and a pair of upper and lower hanger brackets (40) for fastening with the upper and lower hanger bands (20a) (20b) are respectively installed around the pole-mounted transformers (10a) (10b).

[0005] At this time, among the multiple pole-mounted transformers (10a)(10b), for example, the pole-mounted transformer (10b) with capacities of 10kva, 20kva, and 30kva has a hanger spacing of 30cm between the upper and lower pair of hanger brackets (40), and among the multiple pole-mounted transformers (10a) with capacities of 50kva, 75kva, and 100kva has a hanger spacing of 39cm between the upper and lower pair of hanger brackets (40). Therefore, when installing, for example, a pole-mounted transformer (10b) with a different capacity and a pole-mounted transformer (10a) with a different capacity using a lower hanger band (20b), an auxiliary adapter (50) must be additionally installed separately to match the lower height difference between the pole-mounted transformers (10a)(10b) on different sides. This causes inconvenience and hassle, which not only reduces the efficiency of the installation work but also increases the installation cost due to the additional installation of the auxiliary adapter.

Specific details for implementing the invention

[0021] Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, FIGS. 4 to 10, in order to fully understand the present invention. Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be interpreted as being limited to the embodiments described in detail below. It should be noted that in each drawing, identical components may be illustrated with the same reference numerals. Detailed descriptions of known functions and components that are deemed to unnecessarily obscure the essence of the present invention are omitted.

[0022] For reference, regarding the configuration of the present invention, the same names and symbols are assigned to configurations identical to conventional (existing) configurations, and redundant descriptions are omitted.

[0023] A direction-changing hanger band (100) for a multi-type transformer according to the first embodiment of the present invention is provided with first to fourth hanger band sections (100a)(100b)(100c)(100d) so that multiple pole-mounted transformers (10a)(10b) of the same capacity or multiple pole-mounted transformers (10a)(10b) of different capacities can be installed around a utility pole (30). Each of the first to fourth hanger band sections (100a)(100b)(100c)(100d) is composed of a central connecting member (110), a left connecting member (120), and a right connecting member (130).

[0024] That is, the first to fourth hanger band sections (100a)(100b)(100c)(100d) are preferably made of an insulating material or a metal (galvanized steel) with a frictional force greater than a certain amount so that they do not slip when installed on the utility pole (30).

[0025] The central connecting member (110) serves to be connected to the upper or lower portions of a plurality of pole-mounted transformers (10a) (10b) respectively via a pair of upper and lower hanger brackets (40) of a plurality of pole-mounted transformers (10a) (10b), and is formed integrally between the left connecting member (120) and the right connecting member (130) or joined by welding.

[0026] At this time, it is preferable that the central connecting member (110) be formed in a semicircular shape that is outwardly convex, so as to be lower than the upper height of the left connecting member (120) and the right connecting member (130) and lower than the lower height of the left connecting member (120) and the right connecting member (130).

[0027] It is preferable that a fastening hole (112) be formed at the front center height of the central connecting member (110) above so as to be fastened to the lower side of a pair of upper and lower hanger brackets (40) by a combination of a bolt and a nut.

[0028] The above-mentioned left connecting member (120) and right connecting member (130) are formed at the same height while facing each other on the left and right sides via the central connecting member (110), so as to be different in height from the central connecting member (110). They serve to connect the first to fourth hanger band sections (100a)(100b)(100c)(100d) in the circumferential direction, and are formed integrally on the left and right sides with the central connecting member (110) in between, or are joined by welding.

[0029] At this time, it is preferable that the left connecting member (120) and the right connecting member (130) be formed in an inwardly convex semicircle shape so as to be higher than the upper part of the central connecting member (110) and higher than the lower part of the central connecting member (110).

[0030] It is preferable that the left connecting member (120) and the right connecting member (130) are spaced apart by a certain distance equal to the lateral width of the central connecting member (110).

[0031] It is preferable that a first connecting hole (122) be formed on the outer side of the above-mentioned left connecting member (120), in which the first to fourth hanger band portions (100a)(100b)(100c)(100d) are fastened by a combination of bolts and nuts so as to be in close contact with the outer circumference of the utility pole (30).

[0032] It is preferable that a second connecting hole (132) be formed on the outer side of the above right connecting member (130), in which the first to fourth hanger band parts (100a)(100b)(100c)(100d) are fastened by a combination of bolts and nuts so as to be in close contact with the outer circumference of the pole (30).

[0033] It is preferable that the first and second connecting holes (112) (132) are each formed at a central height such that when the first to fourth hanger band parts (100a) (100b) (100c) (100d) are in close contact with the outer circumference of the utility pole (30) and fastened by a bolt and nut assembly, the heights of the left connecting member (120) and the right connecting member (130) of each of the first to fourth hanger band parts (100a) (100b) (100c) (100d) are the same.

[0034] When the hanger spacing of the upper and lower pair of hanger brackets (40) among the multiple pole-mounted transformers (10a) (10b) of different capacities is narrow or a wide height difference occurs, the corresponding central connecting member (110) is oriented so that it is turned up or down by 180 degrees compared to the left connecting member (120) and the right connecting member (130), so the first to fourth hanger band sections (100a) (100b) (100c) (100d) can be used for both upper and lower purposes regardless of whether the hanger spacing of the upper and lower pair of hanger brackets (40) installed in the multiple pole-mounted transformers (10a) (10b) is narrow or a wide height difference occurs.

[0035] Accordingly, in the case of multiple pole-mounted transformers (10a) of the same capacity as shown in FIGS. 4 to 6, since the hanger spacing of the upper and lower pairs of hanger brackets (40) installed on the multiple pole-mounted transformers (10a) is all the same, the central connecting member (110) of the first to fourth hanger band sections (100a) (100b) (100c) (100d) constituting the direction-changing hanger band (100) can be installed in a state where the direction is changed downward.

[0036] However, as shown in FIGS. 7 to 10, if the hanger spacing of the upper and lower pairs of hanger brackets (40) installed on 2-3 of the multiple pole-mounted transformers (10b) (10b) of different capacities is all the same, and the hanger spacing of the upper and lower pairs of hanger brackets (40) installed on one pole-mounted transformer (10b) is narrower and higher than the hanger spacing of the upper and lower pairs of hanger brackets (40) installed on 2-3 pole-mounted transformers (10a), then the central connecting member (110) among the first to fourth hanger band parts (100a) (100b) (100c) (100d) constituting the direction-changing hanger band (100) can be installed by flipping it 180 degrees so that one of the central connecting members (110) is facing upward.

[0037] As such, the present invention is a direction-changing hanger band structure for a multi-type transformer that allows for the simultaneous installation of a pole-mounted transformer of a different capacity and a pole-mounted transformer of the same capacity by flipping only the necessary hanger band part 180 degrees among the direction-changing hanger bands formed by a combination of multiple hanger band parts without using an existing additional auxiliary adapter. Therefore, by eliminating the work process of the existing additional auxiliary adapter, it has the effect of shortening work time and reducing additional costs, as well as improving construction quality.

[0038] Meanwhile, the present invention is not limited to the embodiments described above, but can be implemented with modifications and variations within the scope of the essence of the invention, and such technical concepts to which modifications and variations are applied should also be considered to fall within the scope of the following patent claims.
