내진 기능을 갖는 수배전반{ELECTRIC PANEL OF SEISMIC CAPABILITY}Switchgear with seismic function {ELECTRIC PANEL OF SEISMIC CAPABILITY}

본 발명은 수배전반에 관한 것으로서, 보다 상세하게는 진동에 대한 감쇄 기능과 난연 특성을 함께 갖도록 구성되는 내진 기능을 갖는 수배전반에 관한 발명이다. The present invention relates to a switchgear, and more particularly, to a switchgear having an earthquake-resistant function configured to have both a vibration damping function and a flame retardant characteristic.

일반적으로 빌딩이나 공장 등에서는 그대로 사용할 수 있는 110V 또는 220V의 저압의 전기를 전력회사로부터 직접 공급받을 수는 없다.In general, low voltage 110V or 220V electricity that can be used as it is in a building or factory cannot be directly supplied from a power company.

따라서, 빌딩 등의 자가용 전기설비에서는 229kV의 고압의 전력을 수전하여 다시 상용전압으로 변압하여 이용하는데, 이에 이용되는 장치가 수배전반이다.Accordingly, in a private electric facility such as a building, high-voltage power of 229 kV is received and converted back to a commercial voltage, and the device used for this is a switchgear.

수배전반은 변전소로부터 공급되는 고압의 전력을 공급받기 위한 수전설비와, 변전소로부터 수전된 고압의 전력을 상용전압의 전력으로 강압하기 위한 변전설비 및 강압된 전기를 빌딩 내 각부 전기기기나 조명 등으로 공급하기 위한 배전설비를 포함하여 빌딩 내 각 영역으로 안전하고 효율적으로 전기를 공급하게 된다.The switchgear consists of a power receiving facility for receiving high-voltage power supplied from the substation, a substation facility for stepping down the high-voltage power received from the substation into commercial voltage power, and supplying the reduced electricity to each part of the building, such as electrical equipment or lighting. Electricity will be safely and efficiently supplied to each area in the building, including distribution facilities for

그런데, 바닥의 진동이나 전자기력에 의한 기계적 진동 또는 지진에 의한 진동이 전달되어 수배전반 내부의 구성이 파손되는 경우가 종종 발생되는 실정이다.However, it is a situation in which vibration of the floor or mechanical vibration caused by electromagnetic force or vibration caused by an earthquake is transmitted, so that the structure inside the switchgear is often damaged.

따라서, 지진과 태풍 등의 자연 재해로 인한 구조물의 붕괴사고 및 그로 인한 수전배전반의 파손은 전력 공급 중단을 야기할 수 있으며, 이에 대한 대책이 요구된다.Therefore, the collapse of structures due to natural disasters such as earthquakes and typhoons and the damage of the power switchboard may cause power supply interruption, and countermeasures are required.

바람직하게는, 상기 상부보강부재(30)와 하부보강부재(10) 및 중간탄성부재(20)에서 서로 접촉되는 표면에는 격자 형태의 요철부(12, 22, 32)가 형성된다.Preferably, the surfaces of the upper reinforcing member 30, the lower reinforcing member 10, and the intermediate elastic member 20 in contact with each other are formed with lattice-shaped irregularities 12, 22, 32.
