Description

지중배전의 지상기기함 보호장치{A protect apparatus of an underground transmission line}A protect apparatus of an underground transmission line

본 발명은 지중배전의 지상기기함 보호장치에 관한 것으로서, 더욱 상세하게는 지상기기함이 충격흡수받침에 놓여져 방호대에서 막지 못한 충격력을 뒤로 밀리면서 흡수하여 지상기기함이 파손되지 않게 하는 지중배전의 지상기기함 보호장치에 관한 것이다.The present invention relates to a ground equipment box protection device for underground distribution, and more particularly, the ground equipment box is placed on the shock absorbing support to absorb and absorb the impact force not blocked by the guard, so that the ground equipment box is not damaged. To protect equipment for ground equipment.

일반적으로 변압기는 전압을 필요한 값으로 변환시키는 장치로 송전선으로 수송할 수 있는 전력에는 한계가 있고, 큰 발전소가 수요지에서 멀어지고 있어 긴 송전선으로 큰 전력을 수송해야 한다.In general, the transformer is a device that converts the voltage to the required value, there is a limit to the power that can be transported to the transmission line, the large power plant is moving away from the demand, it is necessary to transport large power to the long transmission line.

이 때문에 송전 전압은 차츰 높아지고 있으나 도로변에 세워진 신호등, 가로등과 같은 각종 교통기구 등에서 이러한 높은 전압은 적당하지 못하기 때문에 낮은 전압으로 변화시켜야 하므로 변압기가 설치되어 사용되고 있다.For this reason, although the transmission voltage is gradually increasing, such a high voltage is not suitable in various traffic devices such as traffic lights and street lamps that are built on the side of the road, and thus a transformer is installed and used.

이러한 변압기는 일면을 개방할 수 있는 캐비넷 내부에 설치되어 전압을 수용하거나, 지상기기함 내부에 신호등이나 가로등에 낮은 전압을 송전하는 전선이 배선된 지중배전 지상기기를 내부에 설치되어 지면에 매설되어 있는 기초대 위에 수직으로 얹혀져 설치된다.These transformers are installed inside the cabinet that can open one side to accommodate the voltage, or the underground distribution ground equipment, which is wired with wires for transmitting low voltage to traffic lights or street lamps, is buried in the ground. It is installed vertically on the foundation.

Fixed and used. However, the bent pipe 1-3 still suffers a problem that the underground distribution ground box is damaged by the vehicle when a vehicle collision occurs due to the immaturity of the vehicle running on the road 4.

차량이 진행되는 방향으로 절곡된 파이프(1-3)가 차량으로부터 지상기기함(1)을 보호하더라도 차량의 충돌되는 힘을 견디지 못하고 지상기기함(1)에 부딪치게 되어 지상기기함(1)을 파손시킨다.Even if the pipe (1-3) bent in the direction in which the vehicle travels protects the ground equipment box (1) from the vehicle, the pipes (1) are not able to endure the impact force of the vehicle, and they collide with the ground equipment box (1). Break.

지상기기함(1)이 파손되면 지상함 내부에 설치된 각종 기기와 변압기 등이 파손되어 전기 배전 사고를 일으켜 지대한 불편을 초래하는 문제가 발생한다.When the ground equipment box 1 is damaged, various devices and transformers installed inside the ground box are damaged, causing electrical distribution accidents, which causes a great inconvenience.
