Description

내진장치를 구비하고 수평조절이 용이한 배전반{the distribution board having earthquake-proof device and for horizontal control}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a distribution board having an earthquake-

본 발명은 내진장치를 구비하고 수평조절이 용이한 배전반(고압 배전반, 저압 배전반, 분전반, MCC)에 관한 것으로, 더욱 상세하게는 종래에는 고전압 배전반, 저전압 배전반, 분전반, MCC(motor control center)와 같이 바닥면에 기립 상태로 설치되던 전기장치를 지진 등에 의한 진동으로부터 보호할 수 있는 내진장치를 구비하고 수평조절이 용이한 배전반(고압 배전반, 저압 배전반, 분전반, MCC)에 관한 것이다.
The present invention relates to a high-voltage switchboard, a low-voltage switchboard, a distribution board, a motor control center (MCC), and a high-voltage switchboard, and more particularly to a switchboard (A high-voltage switchboard, a low-voltage switchboard, a distribution board, an MCC) equipped with an earthquake-resistant device capable of protecting an electric device installed in a standing state on the floor from vibration caused by an earthquake or the like.

최근 빈번해지고 있는 지진과 태풍 등의 자연재해로 인해 구조물의 붕괴사고 및 그로 인한 경제적 손실이 증가하고 있다. 이에 따라 전세계적으로 구조물의 안정성을 확보하려는 노력이 증가하고 있다. 특히 발전소나 교량과 같은 중요 구조물이나 고층빌딩 같은 대형 건축물은 파괴시 엄청난 인명피해와 경제적 손실을 동반할 수 있기 때문에, 국내에서도 이들에 대한 내진설계 기준은 강화되고 있는 실정이다.The collapse of structures and the economic loss caused by natural disasters such as earthquakes and typhoons are increasing. As a result, efforts are being made to secure the stability of structures throughout the world. Especially, large buildings such as power plants and bridges and large buildings such as high - rise buildings can be accompanied by huge loss of life and economic loss in destruction. Therefore, seismic design standards for these buildings are strengthened in Korea.

지진의 강도가 일정 수준 이하일 경우 건물의 진동에 의해 건물 자체는 건전하여도 그 내부의 각종 전기장치나 물건들은 넘어지거나, 서로 충돌하면서 파손될 수 있다. 특히 제어반과 같은 중대형 전기장치는 외부의 진동에 취약한 제어회로, 소자, 스위치 등의 전장품으로 이루어지기 때문에 기계 구조적 강도가 매우 취약하다. 따라서 중대형의 전기장치는 내진구조로 설치되어야 건물의 진동에 의한 파손의 위험을 줄일 수 있다.If the intensity of the earthquake is below a certain level, even if the building itself is sound due to the vibration of the building, various electric devices and objects therein may fall over or collide with each other and be damaged. Particularly, since the middle and large-sized electric devices such as the control panel are made of electrical parts such as control circuits, devices, and switches that are vulnerable to external vibration, mechanical structural strength is very weak. Therefore, the middle- or large-sized electric device should be installed in an earthquake-proof structure to reduce the risk of damage due to the vibration of the building.

전기장치를 지진파로부터 보호하기 위한 기술로 국내 공개특허 제2011-87748호(2011. 8. 3. 공개)에는 전기장치에 대한 내진장치가 개시되어 있다. 상기 공보에 개시된 내진장치는, 전기장치의 함체 양측에 바닥면으로부터 입설되는 서포트가 설치되고, 서포트로부터 함체의 측벽을 향하는 수평축이 마련되며, 수평축과 함체의 측벽 사이에 축방향 및 회전방향으로 탄성을 갖는 탄성 가요성 부재가 배치된 구성으로 이루어진다.As a technique for protecting an electric device from a seismic wave, Korean Patent Laid-Open Publication No. 2011-87748 (published on August 3, 2011) discloses an earthquake-proof device for an electric device. The earthquake-proof device disclosed in the above publication is provided with a support installed on both sides of the enclosure of the electric device, a horizontal axis extending from the support toward the side wall of the enclosure, and an elasticity between the horizontal axis and the side wall of the enclosure And an elastic flexible member having an elastic member.

이러한 종래 내진장치는 전기장치의 함체 양측에 서포트를 설치하고, 함체와 서포트를 탄성 가요성 부재로 연결함으로써, 탄성 가요성 부재가 지닌 탄성력에 의해 축방향 병진운동과 회전운동을 포함하는 복합적인 운동이 가능해진다. 따라서 지진파 등의 외부 진동 에너지를 탄성 가요성 부재에서 흡수함으로써 전기장치를 진동으로부터 보호할 수 있다.Such a conventional earthquake-proof device has a structure in which supports are provided on both sides of the housing of the electric device, and the housing and the support are connected to each other by an elastic flexible member, so that a composite movement including axial translation and rotational movement Lt; / RTI > Therefore, by absorbing the external vibration energy such as a seismic wave from the elastic flexible member, the electric device can be protected from vibration.

그런데 상술한 종래 전기장치용 내진장치는 바닥면에 고정된 한 쌍의 서포트가 전기장치의 양쪽 측면에 결합되어 전기장치를 바닥면으로부터 부상한 상태로 지지하므로, 전기장치가 불안정한 상태에 놓이기 쉽다. 즉 전기장치가 수평축을 회전 중심축으로 하여 회전하여 쉽게 기울어질 수 있다. 특히 무게가 무거운 전기장치에 적용하려면 서포트나 수평축의 강도가 매우 커야하고, 탄성 가요성 부재의 탄성 강도 또한 매우 커야 하므로 설치 비용이 높아진다.
However, in the above-mentioned conventional earthquake-proof apparatus for electric apparatus, a pair of supports fixed on the floor surface is coupled to both sides of the electric apparatus to support the electric apparatus in a floating state from the floor surface, so that the electric apparatus is liable to be placed in an unstable state. That is, the electric device can be easily tilted by rotating about the horizontal axis as the rotation center axis. Particularly, in the case of an electric device having a heavy weight, the strength of the support or the horizontal axis must be very high, and the elasticity of the elastic flexible member must be very large.

등록특허 10-1193469(내진장치를 구비하고 수평조절이 용이한 배전반(고압 배전반, 저압 배전반, 분전반, ＭＣＣ))Patent No. 10-1193469 (an electric switchboard (a high-voltage switchboard, a low-voltage switchboard, a distribution board, an MCC) equipped with an earthquake-proofing device and easily adjustable in level)
