본 발명은 지진발생시 변압기에 절연파괴에 의한 손상이 발생되는 것을 방지할 수 있도록 된 변압용 가공배전기의 고정구조에 관한 것이다.The present invention relates to a fixed structure of a transformer for processing transformers to prevent damage caused by insulation breakdown in the transformer during an earthquake.

일반적으로, 전신주에 가설된 전선을 통해 전기를 전송하는 가공전선의 경우, 지면에 설치된 배전기를 통해 전압을 낮추거나 전기를 배전하고 있다.In general, in the case of overhead wires that transmit electricity through wires installed in the telephone poles, the voltage is lowered or the electricity is distributed through a distributor installed on the ground.

이러한 가공배전함은 도 1에 도시한 바와 같이, 지면에 구비된 콘크리트 재질의 기대(10)와, 상기 기대(10)에 설치된 변압기(20) 및 배전판(30)과, 상기 변압기(20)와 배전판(30)을 덮도록 기대(10)에 설치되는 케이스(40)로 구성되어, 변압기(20)와 배전판(30)에 연결된 전원선(50)을 통해 전압을 낮추거나 전기를 분배하는 배전기능을 할 수 있다.As illustrated in FIG. 1, the overhead distribution box includes a base 10 of concrete material provided on the ground, a transformer 20 and a distribution plate 30 installed on the base 10, the transformer 20 and a distribution plate. Consists of a case 40 installed on the base 10 to cover the 30, the power distribution function to lower the voltage or distribute electricity through the power line 50 connected to the transformer 20 and the power distribution board 30 can do.

한편, 이러한 가공배전함의 변압기(20) 내부에는, 전압을 낮추는 변압유닛이 잠길 정도로 절연오일이 충진된다. 상기 절연오일은 고압의 전원이 인가되는 전압유닛 내부에 방전이 발생되는 것을 방지하는 기능을 한다.On the other hand, the insulating oil is filled in the transformer 20 of the overhead distribution box so that the transformer unit for lowering the voltage is locked. The insulating oil functions to prevent discharge from occurring in the voltage unit to which the high voltage power is applied.

그런데, 이러한 가공배전함은 상기 기대(10)의 상부에 고정설치되므로, 지진이 발생되면 가공배전함 전체, 특히, 변압기(20)가 진동하게 되며, 이에따라, 변압기(20) 내부의 절연오일이 진동하여 절연상태가 손상되는 절연파괴가 발생된다.However, since the process distribution box is fixedly installed on the upper part of the base 10, when the earthquake occurs, the entire process distribution box, in particular, the transformer 20 vibrates, and accordingly, the insulating oil in the transformer 20 vibrates. Insulation breakage occurs that damages the insulation state

특히, 절연유는 변압기(20)가 상하방향으로 진동될 때보다 좌우측으로 진동 될 때 더욱 쉽게 절연파괴가 발생되는데, 일반적으로 도심지에서 발생되는 지진의 경우, 지면이 좌우로 흔들리게 되므로, 변압유닛에 충진된 절연오일이 좌우로 요동치면서 절연파괴가 쉽게 발생된다.In particular, insulation oil is more easily generated when the transformer 20 is vibrated left and right than when the transformer 20 is vibrated in the up and down direction, in the case of earthquakes that occur in urban areas in general, because the ground shakes from side to side, As the filled insulating oil swings from side to side, insulation breakdown occurs easily.

따라서, 지진이 발생되면 절연파괴에 의한 변압기(20)의 손상이 발생되며, 심할 경우, 변압기(20) 내부의 온도가 급속하게 상승되어 변압기(20)가 폭발하게 되는 문제점이 있다.Therefore, when an earthquake occurs, damage to the transformer 20 due to insulation breakdown occurs, and in severe cases, the temperature of the transformer 20 rapidly rises, causing the transformer 20 to explode.

본 발명은 상기의 문제점을 해결하기 위한 것으로서, 지진이 발생되더라도, 변압기내부의 절연파괴 및 이에따른 변압기의 손상이 발생되는 것을 방지할 수 있도록 된 변압용 가공배전기의 고정구조를 제공함에 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and even if an earthquake occurs, it is an object of the present invention to provide a fixed structure of a transformer for processing transformers to prevent the insulation breakdown inside the transformer and the damage of the transformer. have.

이하, 본 발명을 첨부된 예시도면에 의거하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 2내지 도 4에 의하면, 본 발명에 따른 변압용 가공배전기의 고정구조는, 지면에 구비된 콘크리트 재질의 기대(10)와, 상기 기대(10)에 설치되며 전원선(50)에 연결되는 변압기(20) 및 배전판(30)과, 상기 변압기(20)와 배전판(30)을 덮도록 기대(10)에 설치되는 케이스(40)로 구성된 것은 종래와 동일하다.2 to 4, the fixed structure of the transformer for the transformer according to the present invention, the base 10 of the concrete material provided on the ground, and is installed on the base 10 is connected to the power line 50 The transformer 20 and the power distribution board 30 and the case 40 installed on the base 10 to cover the transformer 20 and the power distribution board 30 are the same as in the related art.

그리고, 상기 기대(10)는 콘크리트재질로 구성된 기대본체(11)와; 상기 기대본체(11)의 상면 둘레부에 구비된 복수개의 하부조인트(12)와; 하단이 상기 하부조인트(12)에 연결되어 입설되는 복수개의 지지아암(13)과; 상기 지지아암(13)의 상단에 연결되는 복수개의 상부조인트(14)와; 상기 상부조인트(14)의 상단에 고정되며 상측에 상기 변압기(20)와 배전판(30)이 설치되는 지지대(15)와; 상기 지지아암(13)에 연결된 스프링(16) 및 완충장치(17)로 구성된다.And, the base 10 and the base body 11 composed of a concrete material; A plurality of lower joints 12 provided on an upper circumference of the base body 11; A plurality of support arms 13 having a lower end connected to the lower joint 12; A plurality of upper joints 14 connected to an upper end of the support arm 13; A support 15 fixed to an upper end of the upper joint 14 and having a transformer 20 and a distribution plate 30 installed on an upper side thereof; It is composed of a spring 16 and a shock absorber 17 connected to the support arm 13.

상기 기대본체(11)는 콘크리트를 사각평판형으로 지면에 타설하여 구성된다.The base body 11 is constructed by placing concrete on the ground in a square flat plate shape.

상기 하부조인트(12)와 상부조인트(14)는 4개의 쌍을 이루어 상기 기대본체(11)의 상면과 지지대(15)의 저면 모퉁이부에 상호 대응되도록 배치되는 것으로, 상기 지지아암(13)의 양단에 유니버설조인트 결합되어, 지지아암(13)이 전후좌우방향으로 자유롭게 회동될 수 있도록 지지한다.The lower joint 12 and the upper joint 14 are arranged in four pairs so as to correspond to the upper surface of the base body 11 and the bottom corner of the support 15, and the support arm 13 Universal joints are coupled to both ends to support the support arm 13 so that the support arm 13 can freely rotate in the front, rear, left and right directions.

상기 지지대(15)는 강도가 높은 금속재의 평판으로 구성되어, 상측에 배치되는 변압기(20)와 배전판(30)을 지지할 수 있도록 구성된다.The support 15 is composed of a metal plate of high strength, and is configured to support the transformer 20 and the power distribution plate 30 disposed above.

상기 스프링(16)과 완충장치(17)는 양단이 상기 지지아암(13)과 기대본체(11)의 상면에 구비된 브라켓(18)에 유니버셜 조인트 연결되어, 지지아암(13)이 입설되도록 탄성적으로 지지하며, 지지아암(13)이 어느방향으로 회동되더라도 이에 추종하여, 완충기능과, 진동흡수기능을 한다.Both ends of the spring 16 and the shock absorber 17 are universally connected to the bracket 18 provided on the upper surface of the support arm 13 and the base body 11 so that the support arm 13 can be installed. Sexually supported, the support arm 13 is rotated in any direction to follow the buffer function, and the shock absorbing function and the vibration absorbing function.

이때, 상기 스프링(16)과 완충장치(17)는 도 4에 도시한 바와 같이, 상기 지지아암(13)의 양측에 90도 각도를 이루도록 연결되어, 지지아암(13)이 어느방향으로 회동되라도 지지력을 발휘할 수 있도록 배치된다.At this time, the spring 16 and the shock absorber 17 is connected to both sides of the support arm 13 to form an angle of 90 degrees, as shown in Figure 4, the support arm 13 is rotated in any direction It is also arranged to exert a bearing force.

이와같이 구성된 변압용 가공배전기의 고정구조의 작용을 설명하면 다음과 같다.Referring to the operation of the fixed structure of the transformer for processing transformer configured as described above are as follows.

우선 지진이 발생되지 않았을 때는 도5의 (a)에 도시한 바와 같이, 상기 스프링(16)과 완충장치(17)에 의해 지지아암(13)이 지지되어, 직립된다.First, when no earthquake occurs, as shown in Fig. 5A, the support arm 13 is supported by the spring 16 and the shock absorber 17 to stand upright.

그리고, 지진이 발생되어 기대본체(11)가 좌우측으로 흔들리면, 도 5의 (b)에 도시한 바와 같이, 관성작용에 의해 상기 지지대(15)는 좌우로 움직이지 않으며, 기재본체(11)의 움직임에 따라 지지아암(13)이 좌우로 회동되며 이에따라 상기 지지대(15)가 승강된다. 즉, 도 6에 도시한 바와 같이, 기대본체(11)가 거리 L 만큼 좌우로 이동되면, 지지아암(13)의 회동작용에 의해 수평방향 운동에너지가 수직방향 운동에너지로 전환되어 지지대(15)가 H만큼 상하방향으로 승강된다.Then, when the earthquake occurs and the main body 11 shakes left and right, as shown in FIG. 5 (b), the support 15 does not move left and right by the inertial action, As the support arm 13 rotates from side to side, the support 15 is elevated accordingly. That is, as shown in Figure 6, when the base body 11 is moved left and right by the distance L, the horizontal kinetic energy is converted to the vertical kinetic energy by the rotation of the support arm 13 to support the support (15) Is raised and lowered by H.

따라서, 지진이 발생되어 지면이 좌우로 흔들리면, 상기 지지아암(13)의 회 동작용에 의해 지지대(15) 운동방향이 상하로 바뀌면서 지진에너지의 많은 부분이 흡수될 뿐 아니라, 상기 변압기(20)와 배전판(30)이 설치된 지지대(15)가 상하로 흔들리게 되므로, 절연오일이 좌우로 흔들리때 보다 절연파괴가 발생될 가능성을 현저하게 낮출 수 있는 장점이 있다.Therefore, when an earthquake is generated and the ground shakes from side to side, as the rotational direction of the support arm 15 changes up and down by the rotational movement of the support arm 13, not only a large part of the seismic energy is absorbed, but also the transformer 20 And because the support plate 15 is installed and the distribution plate 30 is shaken up and down, there is an advantage that can significantly lower the possibility of insulation breakdown than when the insulating oil is shaken from side to side.

또한, 상기 지지대(15)는 스프링(16)과 완충장치(17)에 의해 지지되므로, 지진이 멈추면 흔들림이 급속하게 멈추게 되어, 변압기(20)에 불필요하게 흔들림이 발생되는 것을 방지할 수 있는 장점이 있다.In addition, since the support 15 is supported by the spring 16 and the shock absorber 17, the shaking stops rapidly when the earthquake stops, thereby preventing unnecessary shaking from occurring in the transformer 20. There is an advantage.

이상에서와 같이 본 발명에 따른 변압용 가공배전기의 고정구조은 기대(10)가 콘크리트재질로 구성된 기대본체(11)와; 상기 기대본체(11)의 상면 둘레부에 구비된 복수개의 하부조인트(12)와; 하단이 상기 하부조인트(12)에 연결되는 복수개의 지지아암(13)과; 상기 지지아암(13)의 상단에 연결되는 복수개의 상부조인트(14)와; 상기 상부조인트(14)의 상단에 고정되며 상측에 상기 변압기(20)와 배전판(30)이 설치되는 지지대(15)와; 상기 지지아암(13)에 연결된 스프링(16) 및 완충장치(17)로 이루어져, 지진에 의해 수평방향 흔들림이 발생될 경우, 이를 상하방향 운동으로 전환시켜 에너지를 흡수하므로써, 지진이 발생되더라도, 변압기내부의 절연파괴 및 이에따른 변압기의 손상이 발생되는 것을 방지할 수 있는 장점이 있다.As described above, the fixed structure of the transformer for the transformer according to the present invention is the base body 11 is composed of a concrete material base 10; A plurality of lower joints 12 provided on an upper circumference of the base body 11; A plurality of support arms 13 having a lower end connected to the lower joint 12; A plurality of upper joints 14 connected to an upper end of the support arm 13; A support 15 fixed to an upper end of the upper joint 14 and having a transformer 20 and a distribution plate 30 installed on an upper side thereof; It is composed of a spring 16 and the shock absorber 17 connected to the support arm 13, when the horizontal shaking caused by the earthquake, by converting it to the vertical movement to absorb the energy, even if an earthquake occurs, the transformer There is an advantage that can prevent the occurrence of internal insulation breakdown and damage to the transformer.
