Description

충격흡수가 용이한 지중배전의 지상기기함 보호장치{A protect apparatus of an underground transmission line}A protect apparatus of an underground transmission line for easy shock absorption

본 발명은 내부에 지중 배전과 연결되는 변압기 및 스위치 등이 부설되는 지중배선의 지상기기함에 관한 것으로, 더욱 상세하게는 운전자의 부주의로 인해 도로를 주행중인 차량과 추돌시 지상기기함이 손상 없이 안전하게 보호될 수 있도록 개선된 충격흡수가 용이한 지중배전의 지상기기함 보호장치를 제공함에 있는 것이다.The present invention relates to a ground equipment box for underground wiring, in which a transformer and a switch connected to underground power distribution are installed. More specifically, the ground equipment box is safely damaged when a vehicle and a vehicle collide on the road due to inattention of a driver. It is to provide a ground equipment box protection device for underground distribution that is easy to absorb shocks improved to be protected.

일반적으로 전압을 필요한 값으로 변환시키는 장치로 널리 이용되는 변압기는 송전선으로 수송할 수 있는 전력에 한계가 있다. 또한, 도시 발달로 인해 대형 발전소가 수용자들부터 점진적으로 멀어지고 있어 긴 송전선으로 큰 전력을 수송을 위해서는 송전 전압이 높아지지만 도로변에 세워진 신호등, 가로등과 같은 각종 교통기구 등에서 이러한 높은 전압을 낮은 전압으로 변화시키기 위한 변압기를 필요로 하고 있다.In general, a transformer widely used as a device for converting a voltage to a required value has a limitation in power that can be transported by a transmission line. In addition, due to the development of the city, large power plants are gradually moving away from the audience, so the transmission voltage increases to transport large power over long transmission lines, but these high voltages are reduced to low voltages in various traffic devices such as traffic lights and street lamps built on the roadside. I need a transformer to change.

변압기는 일면을 개방되는 캐비넷 내부에 설치되어 전압을 수용하거나, 지상기기함 내부에 신호등이나 가로등에 낮은 전압을 송전하는 전선이 배선된 지중배전 기기가 내부에 부설되어 지면에 매설되는 기초 위에 수직으로 얹혀져 설치되고, 개폐기는 전기회로를 개폐 또는 전환하는데 사용되는 기구 또한 변압기와 마찬가지로 기초 상부에 지상으로 노출되게 설치되어 있다.The transformer is installed inside a cabinet that opens on one side to receive a voltage, or underground power distribution equipment with wires for transmitting low voltage to a traffic light or a street lamp is installed inside the ground equipment box. On top of that, the switchgear is used to open or switch electrical circuits, as well as the transformer, which is installed above the foundation and exposed to the ground.

이처럼 변압기 및 개폐기 등을 수용하는 지중배전의 지상기기함은 기초의 상부에 얹혀진 상태로 노출되므로 기초의 상부는 주로 지면 높이보다 다소 높게 돌출된 상태로 도로변 가장자리에 설치된다.As such, the ground equipment box of underground distribution housing transformers and switchgear is exposed on the upper part of the foundation, so the upper part of the foundation is mainly installed at the edge of the road in a state of protruding somewhat higher than the ground height.

종래에는 지중배전의 지상기기함을 보호하기 위해 기초에 파이프를 절곡하여 앵커볼트로 기초에 고정 또는 보도에 매입 고정해 사용하였다.Conventionally, in order to protect the ground equipment box of underground distribution, the pipe was bent to the foundation and anchored to the foundation with anchor bolts or used to be fixed to the sidewalk.

그러나 도로를 주행하는 차량의 운전 미숙의 요인으로 인하여 차량과 충돌이 발생하면 차량에 의하여 지중배전 지상기기함이 파손되는 문제가 있다. 이는 평상시 절곡된 파이프가 지상기기함을 보호하더라도 운전자의 부주의로 인해 차량이 충돌하는 경우 절곡된 파이프가 차량의 충돌되는 힘을 견디지 못하고 지상기기함에 부딪치게 되어 지상기기함을 파손시킴에 따라 그 내부에 설치된 각종 기기와 변압기를 파손시켜 전기 배전 사고를 초래하였다.However, when a collision with the vehicle occurs due to the immature driving of the vehicle driving on the road, there is a problem that the underground distribution ground equipment box is damaged by the vehicle. This means that even if the bent pipe protects the ground equipment box, if the vehicle collides due to the driver's carelessness, the bent pipe will not endure the collision force of the vehicle and will hit the ground equipment box, thereby destroying the ground equipment box. Damage to various equipment and transformers installed caused electrical distribution accidents.
