Zusammenfassung:The present invention relates to a transformer for a substation with a new structure, which is able to prevent the damage given by an earthquake. According to the present invention, the transformer for a substation has a transformer main body (2) which maintains its stopped status without being shaken to the sides when an earthquake occurs and a base unit (1) and a lower support plate (10) are moved to the sides. Here, a support ball (30) is inserted into a concave groove (11) of the lower support plate (10) such that the concave groove (11) formed on the lower support plate (10) is moved to the sides as well as the lower support plate (10) is moved to the sides. Here, the support ball (30) is elevated upwards along a slope of the inner surface of the concave groove (11). In addition, when the base unit (1) is moved in the opposite direction, the support ball (30) and the lower support plate (10) repeat being lowered and elevated, thereby converting the lateral vibration occurring in the base unit (1) into a vertical vibration and absorbing the vertical vibration. Therefore, the transformer main body (2) is moved to the sides by the kinetic energy of the base unit (1) and the lower support plate (10) moved to the sides by the earthquake, thereby being able to prevent the transformer main body (2) from being damaged. 본 발명은 지진에 의해 손상되는 것을 방지할 수 있도록 된 새로운 구조의 변전소용 변압기에 관한 것이다. 본 발명에 따른 변전소용 변압기는 지진이 발생되어, 기대(1)와 하부지지판(10)이 측방향으로 유동할 경우, 변압기본체(2)는 측방향으로 유동되지 않고 정지된 상태를 유지한다. 이때, 상기 지지볼(30)은 하부지지판(10)의 오목홈(11)에 삽입됨으로, 하부지지판(10)이 측방향으로 유동됨에 따라 하부지지판(10)에 형성된 오목홈(11) 역시 측방향으로 유동되며, 이때, 상기 지지볼(30)이 오목홈(11)의 내부면의 경사를 따라 상측으로 상승된다. 그리고, 기대(1)가 반대방향으로 유동되면, 상기 지지볼(30)과 하부지지판(10)이 하강되었다가 상승되기를 반복하여, 기대(1)에 발생된 측방향 진동을 상하방향 진동으로 변환시켜 흡수한다. 따라서, 지진에 의해 측방향으로 유동되는 기대(1)와 하부지지판(10)의 운동에너지에 의해 변압기본체(2)가 측방향으로 유동되어 변압기본체(2)가 손상되는 것을 방지할 수 있는 장점이 있다.
