Description

지중배전의 지상기기함 보호장치{PROTECT APPARATUS OF AN UNDERGROUND TRANSMISSION LINE}Ground Equipment Box Protection Device for Underground Power Distribution {PROTECT APPARATUS OF AN UNDERGROUND TRANSMISSION LINE}

본 발명은 지중배전의 지상기기함 보호장치에 관한 것으로서, 더욱 상세하게는 기기함이 둘레부에 충격완충체와 보조완충체를 이중으로 구성하고, 또한 기기함의 하단에 스프링완충체를 더 구성하여 차량의 충돌시에 지상기기함이 받는 충격을 완화시켜 줄 뿐만 아니라, 충돌되는 차량이 지상기기함측으로 접촉되지 않도록 함으로써 지상기기함을 보호할 수 있는 지중배전의 지상기기함 보호장치에 관한 것이다.The present invention relates to a ground equipment box protection device for underground distribution, and more specifically, the equipment box is configured to double the shock absorber and the auxiliary buffer at the periphery, and further comprises a spring buffer at the bottom of the equipment box In addition to mitigating the impact of the ground equipment box in the event of a vehicle crash, and to protect the ground equipment box by preventing the crashed vehicle from contacting the ground equipment box side.

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, and large power plants are 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.

또한 개폐기는 전기회로를 개폐 또는 전환시키는데 사용되는 기구로 변압기와 마찬가지로 기초대 상부에 지상으로 노출되게 설치되어 있다.In addition, the switchgear is a mechanism used to open or close an electric circuit and is installed to be exposed to the ground above the foundation as in a transformer.

한편, 이와 같은 구성의 변압기 및 개폐기 등을 수용하는 지중배전의 지상기기함은 기초대의 상부에 얹혀진 상태로 노출되는데, 기초대의 상부는 주로 지면 높이보다 다소 높게 돌출된 상태로 도로변에 설치된 지상기기함을 지지하고 있다.On the other hand, the ground equipment box of the underground distribution housing the transformer and switchgear of such a configuration is exposed on the upper part of the foundation, the upper part of the foundation is mainly installed on the side of the road protruding somewhat higher than the ground height. I support it.

이와 같은 지중배전의 지상기기함은 도 1에 도시된 바와 같이 지중배전 지상기기함(1)을 보호하기 위하여 기초대(2)에 파이프(3)를 절곡하여 앵커볼트로 기초대에 고정 또는 보도에 매입하여 고정해 사용하였다. As shown in FIG. 1, the ground equipment box of the underground distribution is bent or pressurized to the foundation by anchor bolts by bending the pipe 3 to the foundation 2 to protect the underground distribution ground equipment 1. It was purchased by fixing to and used.

그러나 절곡된 파이프(3)는 도로에서 진행하는 차량의 운전 미숙으로 인하여 차량 충돌이 발생되면 차량에 의하여 지중배전 지상함이 파손되는 문제가 여전히 발생되는 데, 차량이 진행되는 방향으로 절곡된 파이프(3)가 차량으로부터 지상기기함(1)을 보호하더라도 차량의 충돌되는 힘을 견디지 못하고 지상기기함(1)에 부딪치게 되어 지상기기함(1)을 파손시킨다.However, the bent pipe 3 still suffers a problem that the underground distribution ground box is damaged by the vehicle when a vehicle collision occurs due to an immature driving of the vehicle running on the road. Even if 3) protects the ground equipment box 1 from the vehicle, it does not endure the impact force of the vehicle and hits the ground equipment box 1, thereby destroying the ground equipment box 1.

이와 같이 차량의 충돌에 의해 지상기기함(1)이 파손되면 지상함 내부에 설치된 각종 기기와 변압기 등이 파손되어 전기 배전 사고를 일으켜 지대한 불편을 초래하는 문제가 발생한다.As such, when the ground equipment box 1 is damaged by the collision of the vehicle, various devices and transformers, etc. installed inside the ground box are damaged to cause an electrical distribution accident, which causes a great inconvenience.

따라서, 지상기기함을 보호하기 위한 보호장치가 안출되고 있는 바, 일예로 등록특허 제10-0811750호인 지중배전의 지상기기함 보호장치에 의하면, 지중의 배전과 연결되어 변압기와 스위치등이 내부에 설치되는 지상기기함이 콘크리트받침위에 놓여진 상태에서 차량의 충돌로 인한 충격으로 파손되는 것을 방지하는 보호방치에 있어서, 콘크리트받침에 다수개의 세로지주와 두개의 중앙세로지주의 하단이 매설됨과 동시에 외부차단판의 차량 진행방향에서 볼 수 있는 외측면에 용접으로 고정되고, 세로지주와 중앙세로지주 사이에 횡으로 가로봉이 고정되며, 가로봉의 사이에 다수개의 세로봉이 고정되고, 가로봉 사이의 세로봉에 탄성체인 충격흡수체가 회전가능하게 고정되며, 두개의 중앙세로지주 사이에 고정된 가로봉에 정면충격흡수체가 회전가능하게 고정되는 방호대와, 방호대의 세로지주 하부에 두면이 용접으로 고정되고, 테두리판이 사각으로 형성되어 콘크리트받침 위에 고정되는 외부차단판과, 콘크리트받침에 형성된 홀과 관통되는 케이블이동홀이 판체에 형성되고, 판체는 콘크리트받침의 상면에 볼트로 고정되되 외부차단판의 내측에 위치하며, 판체의 상면으로 케이블이동홀의 둘레를 따라 스프링지지테두리가 돌출형성되는 내부받침판과, 사각의 바닥판의 둘레 단부에 테두리판이 돌출형성되어 박스체를 이루고, 상부가 개방된 사각의 박스체의 바닥판에 케이블홀이 케이블이동홀보다 작은 직경으로 형성되고, 바닥판의 저면에 스프링지지테두리보다 큰 직경으로 스프링지지테두리가 하방으로 돌출 형성되어 내부받침대 상면에 놓여지는 충격흡수받침과, 일단이 충격흡수받침의 스프링지지테두리 내측면에 고정되고, 타단에 호형의 지지 판이 고정되어 내부받침판의 스프링지지테두리의 외측면에 탄력지지되도록 고정되는 다수개의 스프링과, 탄성체로 이루어진 패드가 지상기기함의 차도측 모서리에 고정되는 충격흡수패드로 구성되어 있다.Therefore, a protective device for protecting the ground equipment box is proposed. For example, according to the ground equipment protection device of underground distribution, which is registered in Korean Patent No. 10-0811750, the transformer and the switch are connected inside the ground. In the protective device that prevents damage caused by the impact of a vehicle crash when the ground equipment box installed is placed on the concrete support, the bottom of the plurality of longitudinal posts and two central vertical posts are embedded in the concrete support and at the same time The plate is fixed by welding to the outer surface visible in the vehicle traveling direction, and horizontal bars are fixed horizontally between the longitudinal column and the central longitudinal column, and a plurality of vertical bars are fixed between the horizontal bars, and the elastic body is arranged on the vertical bars between the horizontal bars. The shock absorber is rotatably fixed, and the front shock absorber is rotated on a horizontal rod fixed between two central longitudinal posts. The shield is securely fixed, two surfaces are fixed by welding at the lower part of the longitudinal column of the guard, and an outer shield plate is formed in a rectangular frame and fixed on the concrete support, and a hole formed in the concrete support and a cable moving hole penetrated to the plate body. It is formed, the plate is fixed to the upper surface of the concrete support with a bolt and located inside the outer shielding plate, the inner support plate, the spring support edge protrudes along the circumference of the cable moving hole to the upper surface of the plate body, the circumference of the rectangular bottom plate The edge plate protrudes at the end to form a box body, and the cable hole is formed on the bottom plate of the rectangular box body with the upper side smaller than the cable moving hole, and the spring on the bottom of the bottom plate is larger than the spring support frame. The support frame is formed to protrude downwards, the shock absorbing support that is placed on the upper surface of the inner support, and one end of the shock absorbing support The spring support frame is fixed to the inner side, and the other end of the arc-shaped support plate is fixed to the outer side of the spring support frame of the inner support plate and a plurality of springs fixed to the outer side of the inner support plate, the pad of the elastic body is fixed to the driveway side edge of the ground equipment box It is composed of a shock absorbing pad.

따라서, 방호대를 설치하여 차량의 충돌시 지상기기함을 보호할 뿐만 아니라 방호대가 충격을 견디지 못해 방호대가 지상기기함에 부딪치게 되었을 때 지상기기함이 뒤로 탄력적으로 밀려 충격이 흡수되고, 방호대의 자체 탄성력에 의해 충격이 흡수되어 차량이 빗겨 부딪치면 충격흡수체가 회전하면서 충격이 흡수되는 효과는 물론, 지상기기함이 놓여지는 충격흡수받침의 스프링지지테두리와 내부받침판의 스프링지지테두리 사이에 설치되는 스프링의 힘에 의해 탄력지지되어 충격에 의하여 지상기기함이 뒤로 밀리면서 충격이 흡수되는 효과를 기대하고 있다.Therefore, by installing a guard, not only protects the ground equipment box in the event of a collision of the vehicle, but also when the guard is not able to withstand the impact and the guard is hit by the ground equipment, the ground equipment box is pushed back elastically to absorb the shock, and the body's own elastic force When the shock is absorbed by the vehicle, the impact absorber rotates and the impact is absorbed, as well as the spring installed between the spring support frame of the shock absorber and the spring support frame of the inner support plate. It is elastically supported by the force, and the ground equipment box is pushed back by the impact, so the impact is expected to be absorbed.

그러나, 차량의 충돌시에 발생되는 충격을 흡수하는 흡수체가 방호대에 고정설치된 충격흡수체에 의해서만 이루어지기 때문에, 충격흡수체에 의해 어느 정도 충격이 흡수된다 하더라도, 빠른 속도로 충돌되는 차량이 충격하중을 상기 방호대에 고정설치된 충격흡수체가 지탱하기에는 다소 부족한 점이 있기 때문에, 결국 방호대가 기기함측으로 밀려 기기함과 차량과의 충돌을 방지하지는 못하고 있는 실정이다.However, since the absorber absorbing the shock generated at the time of the collision of the vehicle is made only by the shock absorber fixed to the guard, even if the shock is absorbed to some extent by the shock absorber, the crashed vehicle will not be able to receive the impact load. Since the shock absorber fixed to the guard is somewhat insufficient to support it, the guard is eventually pushed toward the equipment compartment and thus does not prevent the collision between the equipment compartment and the vehicle.

또한, 기기함의 하부측에 스프링과 스프링 지지판을 더 구성하여 차량의 충돌시에 기기함이 밀려 나가도록 하여 지지함이 받는 충격을 완화시키도록 하고 있으나, 기기함의 내부에 스프링과 스프링 지지판 및 스프링지지테두리와 같은 구성요소들의 설치작업이 용이하지 못하고 다수개의 스프링에 의해 구성됨으로써 설치 비용의 증대를 가져오는 문제점이 있다.In addition, the spring and the spring support plate is further configured on the lower side of the equipment box to allow the equipment box to be pushed out when the vehicle collides to mitigate the impact of the support box. Installation of components such as the rim is not easy, and is composed of a plurality of springs, there is a problem that increases the installation cost.

본 발명은 종래 지상기기함 보호장치가 지닌 문제점을 해결하기 위해 안출된 것으로서, 지상기기함의 외측부에 차량의 충돌시의 충격을 흡수하는 충격완충체와 보조완충체를 이중으로 구성하되, 충격완충체와 보조완충체를 방호대로부터 호형지게 형성하여 충격완충체와 보조완충체가 형상에 의한 자체탄성이 유지되도록 함으로써 차량의 충돌시에 받는 충격흡수를 향상시킬 뿐만 아니라, 지상기기함의 하부에 스프링완충체를 간단한 구성으로 설치하여 설치비용의 부담을 줄이고, 설치작업이 용이하게 이루어지도록 한 지중배전의 지상기기함 보호장치를 제공함에 그 목적이 있다.The present invention has been made in order to solve the problems of the conventional ground equipment box protection device, the shock buffer and the secondary shock absorber that absorbs the impact of the vehicle crash on the outer side of the ground equipment box, but the shock buffer body And auxiliary shock absorbers are formed to be arc-shaped from the guards, so that the shock absorbers and the auxiliary shock absorbers maintain their own elasticity due to their shape. Its purpose is to provide a ground equipment box protection device for underground distribution to reduce the burden of installation cost by installing a simple configuration, and to facilitate the installation work.

상기 목적을 달성하기 위한 수단으로 본 발명인 지중배전의 지상기기함 보호장치는, 지중의 배전과 연결되어 변압기와 스위치등이 내부에 설치되는 지상기기함이 콘크리트받침 위에 놓여진 상태에서 차량의 충돌로 인한 충격으로 파손되는 것을 방지하도록 상기 지상기기함의 외측 둘레부에 수직지지부와 수직지지부를 연결하는 수평지지부로 구성된 방호대가 설치되는 보호장치에 있어서, 상기 방호대의 수직지지부에 끼워지는 2개의 끼움부와, 상기 2개의 끼움부를 호형으로 연결하여 연장되는 완충판이 형성된 충격완충체와; 상기 충격완충체가 설치되는 수직지지부에 끼워져 결합되는 결합부와, 상기 결합부가 끼워진 수직지지부의 외측에 위치되는 상기 충격완충체의 완충판 내면 양측에 밀착되는 밀착부와, 상기 결합부와 밀착부를 호형으로 연결하여 연장되는 보조완충판이 형성된 보조완충체와; 상기 지상기기함이 설치되는 바닥부에 형성된 요입부와, 상기 요입부 내측으로 장입되는 볼형고정부와 상기 볼형고정부로부터 연장되는 걸림편이 형성된 탄성지지부와, 상기 탄성지지부의 걸림편이 내삽되고 내부에 스프링이 수용되는 수용부로 구성되는 스프링완충체가 포함되어 이루어진다.As a means for achieving the above object, the ground equipment box protection device of the present invention underground distribution, due to the collision of the vehicle in a state in which the ground equipment box is connected to the distribution of the underground installed inside the transformer and switch, etc. on the concrete support A protective device comprising a horizontal support for connecting a vertical support and a vertical support to the outer periphery of the ground equipment box to prevent damage from impacts, the protective device comprising: two fitting parts fitted to the vertical support of the protection; An impact buffer having a buffer plate extending by connecting the two fitting portions in an arc shape; A coupling part fitted into the vertical support part on which the impact buffer is installed, a close contact part on both sides of an inner surface of the buffer plate of the shock buffer body positioned outside the vertical support part in which the shock absorber is fitted, and the coupling part and the close contact part in an arc shape. An auxiliary buffer formed with an auxiliary buffer plate extending in connection; An indentation portion formed at a bottom portion of which the ground equipment box is installed, an elastic support portion formed with a ball-type fixing portion inserted into the recess portion, and a catching piece extending from the ball-type fixing portion, and a catching portion of the elastic support portion is interpolated therein; It consists of a spring buffer consisting of a receiving portion for receiving the spring.

본 발명인 지중배전의 지상기기함 보호장치는, 지상기기함의 외측 둘레부에 충격완충체와 보조완충체가 이중으로 구성되어 있음에 따라 차량의 충돌시에 받는 충돌하중을 흡수하는 흡수력이 향상되어 지상기기함의 보호성이 향상된다.In the ground distribution box protection device of the present invention, the shock absorber and the auxiliary shock absorber is composed of two parts on the outer periphery of the ground equipment box, so that the absorbing force to absorb the impact load when the vehicle is crashed is improved. The protection of the ship is improved.

또한, 상기 충격완충체와 보조완충체의 완충판 및 보조완충판이 지상기기함의 외측방향으로 돌출되는 호형으로 형성되어 있음에 따라, 차량의 충돌시에 완충판과 보조완충판 자체에 탄성력이 형성될 수 있어 차량이 지상기기함측으로 밀리는 것을 방지할 수 있다.In addition, since the shock absorber and the sub-buffer buffer plate and the sub-buffer plate is formed in an arc shape protruding outwardly of the ground equipment box, when the impact of the vehicle, an elastic force can be formed on the buffer plate and the auxiliary buffer plate itself. It can be prevented from being pushed toward the ground equipment box.

또한, 지상기기함의 하부측에 스프링완충체가 더 구성되어 있기 때문에, 충격완충체의 1차적 방어와 보조완충체의 2차방어에도 불구하고 차량이 지상기기함과 접촉되더라도 지상기기함이 스프링완충체에 의해 탄성적으로 밀릴 수 있어 지상기 기함의 파손 등을 방지할 수 있다.In addition, since the spring buffer is further configured on the lower side of the ground equipment box, the ground equipment box is spring-loaded even if the vehicle comes into contact with the ground equipment box despite the primary defense of the impact buffer and the secondary defense of the auxiliary buffer. It can be elastically pushed by, and damage to a ground plane flagship can be prevented.
