내진스프링을 이용한 수배전반용 내진장치{Seismic device for distributing board using the seismic spring}Seismic device for distributing board using the seismic spring

본 발명은 내진스프링을 이용한 수배전반용 내진장치에 관한 것으로 보다 상세하게는 지진 등의 지각변동으로 발생되는 진동이나 충격으로 수배전반의 비틀림이나 기울어짐으로 인해 수배전반이 파손을 방지하고 스프링의 탄성계수를 조절하여 무게가 각기 다른 수배전반의 높이 및 수평조절이 용이하도록 한 스프링을 이용한 수배전반용 내진장치에 관한 것이다.
The present invention relates to an earthquake-proof device for a switchgear using a seismic spring. More specifically, the switchgear prevents breakage and tilting of the switchgear due to vibration or shock caused by a crustal change such as an earthquake, and thus, adjusts the elastic modulus of the spring. The present invention relates to an earthquakeproof device for a switchgear using a spring to facilitate height and horizontal adjustment of switchboards having different weights.

주지하는 바와 같이, 변전소는, 발전소에서 생산한 전력을 송전선로 및 배전선로를 통하여 수요가에게 보내는 과정에서 전압과 전류의 변성 및 전력의 배분을 위하여 설치하는 시설의 집합체를 이른다. 한편, 발전전압을 송전전압으로 높이는 변전소를 승압변전소라 하며, 송전전압을 배전전압이나 더 낮은 송전전압으로 낮추는 변전소를 강압변전소라 하며, 강압변전소 중에서 그 기능에 따라 송전전압을 더 낮은 송전전압으로 낮추는 변전소를1차 변전소라 하고, 송전전압을 배전전압으로 바꾸는 변전소를 2차 변전소라고 한다.As is well known, the substation is a collection of facilities that are installed for the distribution of voltage and current and the distribution of power in the process of sending the power produced by the power plant to the demand through transmission and distribution lines. On the other hand, substations that raise the generation voltage to the transmission voltage are called boost substations. Substations that lower the transmission voltage to distribution voltages or lower transmission voltages are called substations. Substations are called lower voltage substations, depending on their function. Substations that are lowered are called primary substations, and substations that convert transmission voltages to distribution voltages are called secondary substations.

이러한 변전소에 설치되는 시설물들로는 변압기,단로기.차단기,조상설비, 피뢰기, 또는 배전반을 예를 들 수 있다. Facilities installed in these substations include transformers, breakers, breakers, ancestor installations, lightning arresters or switchboards.

변전소는 국가의 주요시설로서, 안정적인 전력공급을 저해하는 위해 요소를 사전에 차단하는 것이 매우 중요한다. 한편, 위해 중에서, 지진은 이를 예측하여 대비하기 어렵고, 그 피해 양상 또는 치명적인 광범위하므로, 변전설비, 예를 들면 배전반 에는 다양한 내진 및 방진 기술이 적용되어 사용되고 있다.Substations are the main facilities of the country, and it is very important to cut off the elements in advance to prevent a stable power supply. On the other hand, among the hazards, the earthquake is difficult to anticipate and prepare for the damage, and the damage pattern or fatality is widespread, and various seismic and dustproof technologies are applied to substation facilities, for example, switchboards.

도 1를 참조하여 종래의 배전반에 적용된 내진 및 방진 기술을 상술하면 다음과 같다. 배전반(10)의 하단부(11)에는, 배전반(10)을 지면에 배치하여 고정하기 위한 앵커 볼트(12)가 배전반(10)과 지면 사이에 개재되어 단순 체결되어 있다. 이러한 앵커 볼트(12)에 의한 단순 체결의 경우, 지진에 의한 진동이 배전반으로 직접 전달되어 배전반(10)이 파손되거나 손상될 수 있는 문제점이 있다. 또는, 지면에 의한 진동을 완화하기 위한 방진 패드(13)가 앵커 볼트(12)와 지면 사이에 개재되어, 지진에 의한 진동이 배전반(10)으로 직접 전달되는 것을 완화하기도 한다. 하지만, 이 또한, 치명적이고 광범위한 지진에 의한 진동이 배전반(10)으로 전달되는 것을 완벽하게 차단하기 어렵다.Referring to Figure 1 described in detail the seismic and dustproof technology applied to the conventional switchboard as follows. An anchor bolt 12 for arranging and fixing the switchboard 10 on the ground is interposed between the switchboard 10 and the ground and is simply fastened to the lower end 11 of the switchboard 10. In the case of simple fastening by the anchor bolt 12, the vibration caused by the earthquake is directly transmitted to the switchboard, there is a problem that the switchboard 10 may be damaged or damaged. Alternatively, an anti-vibration pad 13 for alleviating vibration caused by the ground may be interposed between the anchor bolt 12 and the ground, thereby alleviating transmission of the vibration due to the earthquake directly to the switchboard 10. However, this also, it is difficult to completely block the transmission of the fatal and extensive earthquake vibration to the switchboard (10).

상기와 같은 배전반은 지면에 바로 설치되면 지각 변동에 의한 외부의 진동이나 충격 등이 발생시 배전반의 내부 전력기기 및 이러한 전력기기를 상호 연결하는 배선 그리고 보호계전기 등의 전기부품이 손상 또는 파손되기 쉬우며, 이에 따라 발생되는 장애에 의해 전력공급의 중단 및 화재가 야기될 수 있다. When the switchboard is directly installed on the ground, when external vibrations or shocks occur due to earthquake fluctuations, the internal power devices of the switchboard, wirings connecting the power devices, and electrical parts such as protection relays are easily damaged or damaged. As a result, interruptions may result in interruption of the power supply and fire.

한편 첨부도면 도 2에 도시된 바와 같이 종래에는 무게가 각기 다른 수배전반의 설치시 예컨데 하나는 그 무게다 1t이고 연결되는 다른 하나의 수배전반 무게가 2t이라고 하면 바닥면이 수평을 형성하고 있어도 방진 패드(13) 또는 탄성을 갖는 재료로 설치되어 있는 방진수단은 수배전반의 무게에 의하여 가압되어 탄성력에 따른 변위량이 다르게 되어 무게가 2t이 나가는 수배전반이 더 바닥면 쪽으로 이동됨으로 연결이 불가능하게 되는 문제점이 발생하게 된다.
On the other hand, as shown in Figure 2, when installing a switchgear with a different weight in the prior art, for example, one is the weight is 1t and the other switchboard is connected to the weight of 2t, even if the bottom surface is formed of a dust-proof pad ( 13) Alternatively, the dustproof means installed with elastic material is pressurized by the weight of the switchgear, so that the displacement amount according to the elastic force is different, so that the switchboard having a weight of 2t is moved to the bottom surface, making it impossible to connect. do.

이에 본 발명은 상기와 같은 종래의 제반 문제점을 해소하기 위해 안출된 것으로, 지진 등에 의해 수배전반이 요동하더라도 내부에 설치된 전력기기를 상호 연결하는 배선 그리고 보호계전기 등의 전기부품이 손상되지 않아 전력공급이 안정적으로 공급할 수 있도록 하며, 바닥면이 기울어졌거나 수평상태 및 무게 즉 외부적 상태에 관계없이 수배전반의 높이를 용이하게 조절할 수 있으며, 방진 및 내진 효과를 얻음과 동시에 너트에 의하여 수배전반의 상하 높이 조절이 용이하고, 무게가 무겁고 가벼운 수배전반의 혼합 설치시 내진스프링의 탄성력을 조절하여 무게에 따른 탄성체의 변위량에 대하여 능동적으로 대처하도록 하여 높이 조절이 더욱더 용이하도록 한 수배전반용 내진장치를 제공하는데 있다.
Accordingly, the present invention has been made to solve the conventional problems as described above, and even if the switchgear fluctuates due to an earthquake or the like, electrical parts such as wirings and protection relays interconnecting the power devices installed therein are not damaged and thus the power supply is reduced. It can supply stably and can easily adjust the height of switchgear regardless of the inclined floor, horizontal state and weight, external condition.

상기 고정플레이트(10)의 원통(12) 바닥중심에 형성된 나사공(14)에 삽입결합되어 상,하로 이동하는 탄성조절나사(22)가 설치하되 상기 탄성조절나사(22)가 원통(12)의 내측으로 돌출되는 상측면에는 원형판재의 가압부재(24)가 설치되며 상기 가압부재(24)의 상측면에는 내진스프링(26)가 설치된 탄성조절부재(20)가 설치되어 도 7a,7b에 도시된 바와 같이 수배전반(100)의 중량에 따른 내진스프링의 교체가 없이 내진스프링의 탄성력을 조절하여 무게에 따른 탄성체의 변위량에 대하여 능동적 대처할 수 있고 지진 및 건물의 충격에 의해 상하 작용시 충격을 완화는 효과가 있다.  The elastic adjustment screw 22 is inserted and coupled to the screw hole 14 formed at the bottom center of the cylinder 12 of the fixing plate 10 to move up and down, but the elastic adjustment screw 22 is cylindrical 12. The upper side protruding into the inner side of the pressing member 24 of the circular plate is installed, the upper side of the pressing member 24 is provided with an elastic adjustment member 20 is installed with a seismic spring 26 is shown in Figure 7a, 7b As shown in the figure, by adjusting the elastic force of the seismic spring without replacing the seismic spring according to the weight of the switchgear 100, it is possible to actively cope with the displacement of the elastic body according to the weight, and to mitigate the impact during the vertical action by the earthquake and the impact of the building. Is effective.

즉, 수배전반(100)의 중량에 따라 탄성조절나사(22)를 상,하로 이동시키면, 가압부재(24)는 내진스프링(26)의 가압하고 상기 내진스프링(26)은 지지부재(30)을 가압하게 되어 수배전반(100)의 높이가 일정하게 유지되는 효과가 있다.That is, when the elastic adjustment screw 22 is moved up and down according to the weight of the switchgear 100, the pressing member 24 presses the seismic spring 26 and the seismic spring 26 supports the support member 30. Pressurization has an effect that the height of the switchgear 100 is kept constant.

또한, 내진스프링(26)은 지진 등에 의해 지면이 요동하여 내진장치(1)가 좌,우로 흔들시 원상의 위치로 복귀시키는 효과도 있다. In addition, the seismic spring 26 has the effect of returning to the original position when the earthquake shakes the ground due to an earthquake or the like.

상기 탄성조절나사(22)가 상,하로 이동이 용이하도록 상기 원통(12) 바닥 중심부에는 나사공(14)이 형성하되 상기 나사공(14) 하단부에는 소정의 공간부로 이룬 관통공(15)이 형성되는 것이 바람직하다.In order to facilitate the elastic adjustment screw 22 to move up and down, a threaded hole 14 is formed at the bottom center of the cylinder 12, and a through hole 15 formed of a predetermined space is formed at a lower end of the screwed hole 14. It is preferably formed.

즉, 상기 관통공(15)은 탄성조절나사(22)를 회전시키기 위해 부수적인 도구를 이용하여 회전시 작업공간을 확보해 주는 것이 바람직하다. That is, the through hole 15 is preferably used to secure the working space during rotation by using an additional tool to rotate the elastic adjustment screw 22.

상기 고정플레이트(10)의 원통(12)에 삽입되는 지지부재(30)는 소정의 거리(L)로 이격되어 형성되는 것이 바람직하다.The support member 30 inserted into the cylinder 12 of the fixed plate 10 is preferably formed to be spaced apart by a predetermined distance (L).

즉, 상,하 조절시 및 충격에 의해 상,하 이동시 상기 고정플레이트(10)의 원통(12)과 지지부재(30)의 흡수수단(34)이 마찰되어 흡수수단(34)이 마모되는 것을 방지할 수는 효과가 있다. That is, when the up and down movement and the up and down movement by the impact up and down, the cylinder 12 of the fixed plate 10 and the absorbing means 34 of the support member 30 are rubbed and the absorbing means 34 is worn. Prevention is effective.

상기 원통(12)의 외주면에 형성된 원형돌기(16)는 원통(12)의 하단에 형성되는 것보다는 중심부나 중심부의 상단에 형성되는 것이 바람직하다. The circular protrusions 16 formed on the outer circumferential surface of the cylinder 12 are preferably formed at the center or the top of the center rather than being formed at the bottom of the cylinder 12.

이와 같이 원통(12)의 외주면에 형성된 원형돌기(16)는 도 8a,8,b에 도시된 바와 같이 상기 고정플레이트(10)의 원통(12)와 지지부재(30)의 결합되는 부분이 최소하여 충격전달이 최소로 전달되고 지진 및 충격에 의해 전,후,좌,우로 소정의 θ각도로 요동시 상기 원통(12)의 외주면에 형성된 원형돌기(16)가 중심축을 역할하기 때문에 상기 지지부재(30)가 흔들시 안정적으로 흡수수단(26)이 충격을 완화할 수 있고, 더욱더 내진스프링(26)에 의해 수배전반에 충격으로 완화 및 원상으로 복귀를 할 수 있는 효과가 있다. As such, the circular protrusion 16 formed on the outer circumferential surface of the cylinder 12 has a minimum portion at which the cylinder 12 and the support member 30 of the fixing plate 10 are coupled as shown in FIGS. When the shock transmission is transmitted to the minimum and the front and rear, left, right by the earthquake and shock swings at a predetermined θ angle due to the circular projection 16 formed on the outer peripheral surface of the cylinder 12 serves as the central axis When the 30 is shaken, the absorbing means 26 can reliably alleviate the shock, and furthermore, the seismic spring 26 has the effect of mitigating and returning to the original state by the impact on the switchboard.

또한 도 9c,9d에 도시된 바와 같이 상,하로 흔들린 경우에는 1차적으로 상기 탄성조절부재(20)의 내진스프링(26)이 충격을 흡수하며 상,하 이동시 상기 원통(12)의 외주면에 형성된 원형돌기(16)는 가이드 역할을 하는 기능을 하며 원형돌기(16)에 전달된 충격은 흡수수단(34)이 충격을 완화해 주는 효과가 있다. In addition, as shown in Figures 9c, 9d, when shaken up and down, the seismic spring 26 of the elastic control member 20 is primarily absorbed shock and formed on the outer circumferential surface of the cylinder 12 when moving up and down The circular protrusions 16 serve as a guide, and the shock transmitted to the circular protrusions 16 has an effect of alleviating the impact of the absorbing means 34.

즉, 흡수수단(34)와 내진스프링(26)은 진동에 의한 파동의 진행방향과 매질이 이동방향이 같은 P파(primary wave)와 진행방향과 매질의 이동방향이 수직인 S파(secondary wave) 두 가지에 의해 발생되는 충격이 배전반 내부에 전력기기들에 영향을 미치지 않도록 완충역할을 하는 것이다. That is, the absorbing means 34 and the seismic spring 26 are P waves (primary wave) in which the traveling direction of the wave due to vibration and the moving direction of the medium are the same, and S wave (secondary wave) in which the moving direction and the moving direction of the medium are perpendicular to each other. The shock caused by the two is to buffer the power equipment inside the switchboard.

이와 같이 구성된 본 발명의 내진스프링을 이용한 수배전반용 내진장치(1)는 도 9,10에 도시된 바와 같이 수배전반를 지지할 수 있도록 하부프레임에 설치시 하나 내지 둘 이상으로 형성될 수 있으나 안정적인 구조는 넷 이상으로 형성되는 것이 바람직하다. The seismic device 1 for the switchgear using the seismic spring of the present invention configured as described above may be formed in one or two or more when installed in the lower frame to support the switchgear as shown in FIGS. It is preferable to be formed above.

상술한 바와 같이 본 발명에 따른 내진스프링을 이용한 수배전반용 내진장치는 수배전반의 하측에 설치되어 지진 등에 의해 지면이 흔들리게 되면 완충작용에 의해 그 충격파가 수배전반으로 직접 전달되지 않아 수배전반 내부의 전력기기를 충격으로 부터 보호하며, 또한 전력기기 손상으로 인한 누전을 방지하여 인명 피해를 막을 수 있고, 외부적 상태에 관계없이 수배전반의 높이를 용이하게 조절할 수 있으며, 방진 및 내진 효과를 얻음과 동시에 너트에 의하여 수배전반의 상하 높이 조절이 용이하고, 무게가 무겁고 가벼운 수배전반의 혼합 설치시 내진스프링의 탄성력을 조절하여 무게에 따른 탄성체의 변위량에 대하여 능동적으로 대처하도록 함으로서 높이 조절이 편리한 이점 등이 있는 효과가 있다.
As described above, the seismic device for the switchgear using the seismic spring according to the present invention is installed on the lower side of the switchgear, and the ground wave is shaken by an earthquake, etc. It protects against shocks and also prevents short circuits caused by damage to power equipment, thereby preventing human damage, and easily adjusts the height of switchgear regardless of external conditions. It is easy to adjust the height of the top and bottom of the switchboard, and by adjusting the elastic force of the seismic spring when the weight and weight of the switchgear is mixed, it has the advantage that the height adjustment is convenient to actively cope with the displacement of the elastic body according to the weight.
