Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing an underground electric power facility,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing a buried underground power facility structure for constructing an underground power facility connected to a power line and performing transforming and opening and closing through a buried structure, And a method of constructing a buried structure of an underground power plant capable of enhancing the safety of the ground and enhancing the space utilization by burying power facilities such as a power plant,

Generally, the power supply is divided into the transmission field and the substation and distribution field.

In the above, the generation of electricity in the initial power plant to supply power to the substation is referred to as transmission, and the power supply from the substation to the consumer is referred to as power distribution.

Typical power distribution systems take power from substations to receptacles to supply power from the ground and underground with both utility power and underground power.

Of the systems that are powered by the earth, the first distribution cables output from the substation are connected to the switchgear after passing through power structures (power manholes) and hand holes in the ground.

In the above, the switch controls whether or not to supply the electric power transmitted through the first distribution cables to the reception place.

The second distribution cables output from the switch are connected to a transformer, and the transformer lowers the high voltage power transmitted through the second distribution cables.

The lowered power by the transformer is supplied to the receiver via the third distribution cables.

In such a distribution system, roadway manholes are generally installed on roads, whereas handholes, switches and transformers are mainly installed on sidewalks and public areas.

Here, the hand hole is installed in the ground, but the switch and the transformer are installed on the ground for easy management.

As described above, since the hand hall, the switch, and the transformer occupy different areas, the construction cost of the distribution system increases because a lot of land must be purchased or leased to construct the distribution system .

In addition, there is a problem that the cables are intertwined with each other when the cables are connected to the switchgear or the transformer. As a result, the cables are broken and it is difficult to distinguish the desired cables at the time of maintenance.

In addition, since the switchgear and the transformer are installed on the ground, they deteriorate the beauty of the city, adversely affect pedestrian safety of the pedestrian, and cause a problem of difficulty of walking, a power failure due to a vehicle collision, and a social cost.

The applicant of the present invention has proposed Korean Patent Registration No. 10-1044558 (name: integrated manhole structure) in order to solve the above-mentioned conventional problems.

The integrated manhole structure disclosed in Korean Patent Registration No. 10-1044558 proposed by the applicant of the present invention is a manhole structure in which at least a part of the manhole structure is buried in the ground, And a transformer portion disposed on the upper surface of the manhole portion and acting as a transformer, wherein at least a part of the transformer portion is exposed to the ground, at least one of the side surfaces of the manhole portion has first through holes, And a first power distribution cable connected to the transformer through the second through hole, the transformer being connected to the transformer through a second through-hole formed between the transformer unit and the first through- And the second power distribution cable output from the second power supply unit is drawn out to the outside through one of the second through hole and the first through hole.

Accordingly, since the integrated manhole structure is realized by integrating the functions of the transformer, the switch, and the manhole, the cost for constructing the power distribution system can be reduced, and the cost of the power distribution system can be reduced within the manhole portion of the integrated manhole structure. Since the cables are directly connected, the entangling of the cables does not occur, so that breakage of the power distribution cable can be prevented and maintenance can be easily performed.

However, a part of the electric power facilities such as the transformer unit and the opening / closing unit is exposed to the sidewalks, which hinders the beauty of the city.

In recent years, there have been proposed apparatuses and means for allowing a part of a power facility such as a transformer, a switch, and the like to be exposed to the outside without being exposed to the outside and being able to smoothly walk on the pedestrian without harming the beauty of the city.
