Description

[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 an electricity distribution device 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 side 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-mentioned conventional power distribution systems suffer from problems such as loss of power due to heat generated by the internal transformer and power equipment and external solar heat, and also problems with the performance and safety of 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 electric equipment inside. Dirt, dust, and harmful exhaust gases from automobiles enter through these exhaust openings, causing damage to the electric equipment inside.

[0006] When filters are installed to prevent the intrusion of dirt and dust, there is a problem in that a lot of maintenance costs are required 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 of this document is to

[0008] Furthermore, in order to achieve the above object, the electric power equipment 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 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, As a result, the cold temperature of the ground cools the heat exchange pipes in the manhole buried underground where the distribution box is installed, and the cooled liquid is sent as gas to the heat exchange pipes installed at the top inside the distribution box by 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 exhaust port provided at the bottom are connected to a heat exchange pipe buried along an input / output distribution line connected to a manhole buried in the ground where the distribution box is installed, and the internal gas is circulated to the heat exchange pipe provided at the top of the distribution box by the circulation device, As a result, the cold temperature of the ground cools 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. Effect of the Invention

[0010] The present invention can reduce the internal temperature of the switch box, thereby reducing the loss of power, thereby preventing global warming and saving energy.

[0011] By reducing the temperature of the switch box according to the present invention, it is possible to reduce the influence of heat generated from the internal transformer and power equipment and the 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, no filters are required and there is no need for regular cleaning and replacement, reducing maintenance costs.

[0014] By incorporating heat exchange piping inside the wall and bottom of the manhole, manufacturing and installation costs can be reduced. [Brief description of the drawings]
