[Technical Field]

[0001] The present invention relates to a ground power equipment device that distributes electricity to consumers due to the elimination of utility poles in urban areas, and more particularly to a power distribution device that is installed on the road or within a consumer's premises. [Background technology]

[0002] Conventional power distribution equipment (power distribution transformer equipment), as shown in Patent Documents 1 and 2, for example, has ventilation openings for intake and exhaust on the sides and top. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 4732936 [Patent Document 2] Patent No. 6759178 Summary of the Invention [Problem to be solved by the invention]

[0004] The above-described conventional power distribution systems suffer from power loss due to heat generated by the internal transformers and power equipment and external solar heat, and also pose performance and safety problems for the internal power equipment.

[0005] For this reason, ventilation openings for intake and exhaust are installed on the sides and top to release the heat generated by the internal power equipment. Dirt, dust, and harmful automobile exhaust fumes enter through these openings, causing harm to the internal power equipment.

[0006] If a filter is installed to prevent the intrusion of dirt and dust, there is a problem in that it requires a lot of maintenance costs for regular cleaning and replacement.

[0007] The present invention provides a power equipment device that solves these problems and controls the rise in the internal temperature of a distribution box. The purpose is to

[0008] Furthermore, in order to achieve the above object, the electric power equipment device of the present invention has a structure in which a heat exchange piping provided at the upper part of the distribution box and a heat exchange pipe provided inside the wall and inside the bottom of a manhole buried underground where the distribution box is installed are connected by a piping with a circulation device provided in between, and the liquid inside is circulated to the heat exchange pipe provided at the upper part of the distribution box by the circulation device, This allows the cold temperature of the ground to cool the heat exchange pipes in the manhole buried underground where the distribution box is installed, and the cooled liquid is then sent as gas to the heat exchange pipes installed at the top inside the distribution box using a pre-circulation device, thereby reducing the internal temperature of the distribution box.

[0009] In order to achieve the above object, the electric power equipment of the present invention has a structure in which an intake port provided at the top of a distribution box and an outlet provided at the bottom are connected to heat exchange pipes buried along input / output distribution lines connected to manholes buried underground where the distribution box is installed, and the heat exchange pipes are connected by piping with a circulation device provided in between, and the internal gas is circulated to the heat exchange pipes provided at the top of the distribution box by the circulation device, This allows the cold temperature of the ground to cool the heat exchange pipe in the manhole buried underground where the distribution box is installed, and the cooled gas is sent by a pre-circulation device to the heat exchange pipe installed at the top inside the distribution box, thereby reducing the internal temperature of the distribution box. [Effects of the Invention]

[0010] The present invention reduces the internal temperature of the distribution box, thereby reducing the loss of power that would otherwise be lost, thereby preventing global warming and saving energy.

[0011] By reducing the temperature of the distribution box according to the present invention, it is possible to reduce the influence of heat generated by the internal transformer and power equipment and external solar heat on the internal power equipment.

[0012] By sealing the inside of the distribution box, it is possible to prevent the intrusion of dirt, dust, harmful automobile exhaust fumes, etc., and to prevent harm to the electric equipment inside.

[0013] By sealing the inside of the distribution box, there is no need for filters and regular cleaning and replacement is no longer necessary, which reduces management costs.

[0014] By incorporating heat exchange piping inside the wall and bottom of the manhole, costs for fabrication and installation can be saved. [Brief explanation of the drawings]
