본 발명은 수배전 장치에 관한 것으로, 더욱 상세하게는 판스프링을 이용하여 외부로부터 전달되는 진동을 저감시키도록 이루어진 내진 수배전 장치에 관한 것이다.The present invention relates to a water distribution apparatus, and more particularly, to a seismic water distribution apparatus configured to reduce vibrations transmitted from the outside using a leaf spring.

일반적으로, 수배전반은 산업용 전력을 사용자에게 안전하게 공급해주는 전기용 설비의 한가지로서, 발전소나 변전소에서 보내진 전력을 수용가(주로 고압수용가)에게 수배전할 때 전기계통의 감시와 제어 및 보호를 위해 사용되는 장치이다.In general, a switchgear is a type of electrical equipment that safely supplies industrial power to a user, and is a device used to monitor, control, and protect an electric system when power is distributed from a power plant or a substation to a consumer (mostly a high voltage consumer). to be.

이와 같은 수배전반은 차단기나 보호계전기 등과 같은 단위 기기를 부착, 지지하는 구조물과 단위 기기를 접속 및 연결시키는 도체물(Busbar, Cable등)의 집합체로 구성되어 있으며, 이러한 각종 전기기기들을 사각형의 철재 외함에 안전하게 절연 수납한 제품이다.The switchgear consists of a collection of structures for attaching and supporting unit devices such as breakers and protective relays, and conductors (Busbars, cables, etc.) connecting and connecting the unit devices. Safely insulated and stored in the product.

수배전반의 외함 내에 포함된 다양한 단위 전기기기들은 진동에 매우 취약하므로 수배전반으로 전달되는 진동을 최소화하도록 방진설계가 되어야 한다.Various unit electric devices included in the enclosure of the switchgear are very vulnerable to vibration and should be designed to be dustproof to minimize the vibration transmitted to the switchgear.

그러나 종래의 수배전반은 외함에 다양한 단위 전기기기들을 내장한 상태에서 바닥에 직접 설치됨으로써 방진설계가 되지 않아 외부로부터 전달되는 진동에 취약한 문제점이 있다. 또한, 전원설비에 대한 내진설계 의무화와 관련하여 수배전반에 대한 방진설계는 필수적으로 요구된다.However, the conventional switchgear is vulnerable to vibration transmitted from the outside because it is not designed to be dustproof by being installed directly on the floor in a state in which various unit electric devices are built into the enclosure. In addition, in connection with mandatory seismic design of power supply facilities, it is essential to make a dustproof design for switchgear.

본 발명의 목적은 전술한 바와 같은 종래의 문제점을 해소하기 위하여 안출된 것으로, 외부로부터 전달되는 진동을 최소화할 수 있는 판스프링을 이용한 수배전 장치를 제공하는데 있다.

이하에서는 본 발명의 바람직한 실시예에 따른 판스프링을 이용한 수배전 장치를 상세히 설명하기로 한다.
Hereinafter, a water distribution apparatus using a leaf spring according to a preferred embodiment of the present invention will be described in detail.

도 1은 본 발명에 따른 판스프링을 이용한 수배전 장치의 사시도이고, 도 2는 도 1의 측면도이다.1 is a perspective view of a water distribution apparatus using a leaf spring according to the present invention, Figure 2 is a side view of FIG.

본 발명에 따른 판스프링을 이용한 수배전 장치(1)는 수배전반(10)의 하부 전후측에 판스프링(20)의 설치를 위한 ‘∩’형태의 찬넬(30)이 각각 마련된다.The water distribution apparatus 1 using the leaf spring according to the present invention is provided with a channel (30) of the '∩' type for the installation of the leaf spring 20 in the lower front and rear sides of the distribution panel (10).

판스프링(20)은 찬넬(30)과 바닥에 결합되어 바닥에 대하여 수배전반(10)을 탄성 지지함으로써 외부로부터 수배전반(10)으로 전달되는 진동을 저감시킨다.The leaf spring 20 is coupled to the channel 30 and the bottom to elastically support the switchboard 10 with respect to the floor to reduce the vibration transmitted from the outside to the switchboard 10.

도 3은 도 1 및 도 2에 도시된 판스프링 및 수배전반, 그리고 바닥의 결합상태를 나타낸 단면도이다.3 is a cross-sectional view showing a coupling state of the leaf spring and switchgear, and the bottom shown in FIGS.

찬넬(30)의 길이는 수배전반(10)의 좌우 길이와 동일하게 형성된다.The length of the channel 30 is formed to be the same as the left and right length of the switchboard (10).

판스프링(20)은 전체적으로 활모양으로 형성되고, 동일한 형상을 갖되 길이가 다른 복수 개의 탄성판(21)이 면접된 구조로 이루어지며, 상부로 가면서 탄성판(21)의 길이가 짧아지고, 탄성판(21) 중 최하부에 위치되는 탄성판(21)의 양단부가 찬넬(30)의 상부에 접면되어 찬넬(30)을 지지하게 된다.The leaf spring 20 is formed in a bow shape as a whole, and has a structure in which a plurality of elastic plates 21 having the same shape but different lengths are interviewed, and the length of the elastic plates 21 is shortened while going upward. Both ends of the elastic plate 21 located at the bottom of the plate 21 are folded to the upper portion of the channel 30 to support the channel 30.

탄성판(21)은 양단부에서 중심측으로 가면서 하향 경사지게 형성된 후 제1변곡점(21a)에서 방향이 전환되어 다시 상향 경사지게 형성되고, 중심부에 제2변곡점(21b)이 형성된다. 이 때, 두 제1변곡점(21a)에서 바닥과 각각 결합되고 제2변곡점(21b)에서 찬넬(30)의 상부와 결합된다.The elastic plate 21 is formed to be inclined downward while going from the both ends to the center side, and the direction is changed at the first inflection point 21a to be inclined upward again, and a second inflection point 21b is formed at the center. At this time, the two first inflection points 21a are coupled to the bottom, respectively, and the second inflection point 21b is coupled to the top of the channel 30.

복수 개의 탄성판(21)은 길이가 다르지만 각 변곡점(21a)(21b)의 위치가 동일하고 경사면의 경사각이 동일하므로 도3과 같이 서로 접면되면서 적층된다.The plurality of elastic plates 21 are different in length, but because the positions of the inflection points 21a and 21b are the same and the inclination angles of the inclined surfaces are the same, they are stacked while being in contact with each other as shown in FIG. 3.

판스프링(20)은 각 탄성판(21)의 두 제1변곡점(21a)을 각각 관통하는 앙카볼트(40)에 의해 바닥에 고정되며, 제2변곡점(21b)을 관통하는 찬넬고정볼트(50)에 의해 찬넬(30)의 상부에 고정된다. 따라서, 판스프링(20)과 바닥의 고정점은 두 제1변곡점(21a)으로 2개소이며, 판스프링(20)과 찬넬(30)의 고정점은 제2변곡점(21b)으로 1개소이다. 판스프링(20)을 구성하는 탄성판(21) 중 최하부에 위치되는 탄성판(21)의 길이는 찬넬(30)의 길이와 같거나 거의 유사하게 형성되어 수배전반(10)을 안정적으로 지지한다.The leaf spring 20 is fixed to the floor by an anchor bolt 40 penetrating the two first inflection points 21a of each elastic plate 21, and the channel fixing bolt 50 penetrates the second inflection point 21b. It is fixed to the top of the channel (30) by. Therefore, the fixed points of the leaf spring 20 and the bottom are two places with the two first inflection points 21a, and the fixed points of the leaf spring 20 and the channel 30 are one place with the second inflection points 21b. The length of the elastic plate 21 located at the bottom of the elastic plate 21 constituting the leaf spring 20 is formed to be substantially the same as or similar to the length of the channel 30 to stably support the switchboard (10).

찬넬(30)과 판스프링(20) 사이에는 외부로부터 수배전반(10)으로 전달되는 진동을 저감시키는 방진패드(60)가 개재된다. 방진패드(60)는 판스프링(20)의 상부 중심에 위치되며 그 중심을 찬넬고정볼트(50)가 관통된다. 따라서 찬넬고정볼트(50)에 의해 판스프링(20)과 방진패드(60)가 동시에 찬넬(30)에 고정된다.Between the channel 30 and the leaf spring 20, there is an anti-vibration pad 60 for reducing the vibration transmitted to the switchboard 10 from the outside. The anti-vibration pad 60 is located at the upper center of the leaf spring 20 and the channel fixing bolt 50 penetrates the center thereof. Therefore, the plate spring 20 and the anti-vibration pad 60 are fixed to the channel 30 by the channel fixing bolt 50 at the same time.

이와 같은 구성을 갖는 본 발명 판스프링을 이용한 수배전 장치(1)에 의하면 수배전반(10)은 판스프링(20)과 방진패드(60)에 의해 탄성 지지되므로, 지진 등에 의해 바닥으로부터 전달되는 진동이 2차에 걸쳐 효율적으로 저감된다.According to the water distribution apparatus 1 using the leaf spring of the present invention having such a configuration, since the switch panel 10 is elastically supported by the leaf spring 20 and the dustproof pad 60, vibration transmitted from the floor by an earthquake or the like is prevented. It is efficiently reduced over two orders.

또한, 수배전반(10)을 지지하는 판스프링(20)과 바닥의 고정점이 2개소로 판스프링(20)의 중심으로 기준으로 양쪽으로 대칭된 위치에 각각 형성되며, 수배전반(10)의 하부에 결합되는 찬넬(30)과 판스프링(20)의 고정점은 1개소로 판스프링(20)의 중심에 형성되고, 판스프링(20)의 양단이 찬넬(30)에 접촉되어 찬넬(30)을 지지한다. 따라서, 수배전반(10)은 판스프링(20)에 의해 안정적으로 지지된다.
In addition, the leaf spring 20 supporting the switchboard 10 and the bottom fixing points are formed at two positions symmetrically on both sides with respect to the center of the leaf spring 20, respectively, coupled to the lower portion of the switchboard 10. Fixed points of the channel 30 and the leaf spring 20 are formed at the center of the leaf spring 20 in one place, and both ends of the leaf spring 20 are in contact with the channel 30 to support the channel 30. do. Therefore, the switchboard 10 is stably supported by the leaf spring 20.

이상에서 설명한 바와 같이, 본 발명 판스프링을 이용한 수배전 장치를 바람직한 실시예를 기초로 상세히 설명하였으나, 본 발명은 특정 실시예에 한정되는 것은 아니며, 해당분야 통상의 지식을 가진 자가 특허청구범위에 기재된 범주 내에서 다양하게 변형 실시할 수 있다.As described above, the water distribution apparatus using the leaf spring of the present invention has been described in detail based on the preferred embodiment, but the present invention is not limited to the specific embodiments, and those of ordinary skill in the art Various modifications can be made within the scope described.
