[0003] In such a switchgear, a switchgear having a predetermined volume and having a door is usually provided with an inlet for receiving electric power from a power distribution line, an automatic section switch connected in series to the inlet of the automatic switch section, A transformer current transformer connected in series to the downstream of the power fuse for protection of the transformer current transformer, a transformer current transformer for the power supply and demand device connected in series to the transformer transformer for power supply and demand, A transformer in which the primary side is connected in series downstream of the transformer current transformer for power supply for measuring electricity, a main breaker connected to the secondary side of the transformer, And a plurality of wiring breakers for blocking the respective loads when necessary.

In addition, the enclosure of such a switchboard can be constructed by assembling an anchor bolt on a concrete floor surface inside or outside the building, assemble the floor angle, assembling the column angle on the floor angle, and assembling the enclosure on the assembled column angle, This bottom angle is assembled by bolt tightening, and seismic design is not done separately.

However, in the conventional switchgear, the vibration condition is directly transmitted to the panel itself due to the mechanical vibration or the earthquake caused by the electromagnetic force due to the vibration of the floor or the energization of the large electric power, so that various devices installed in the panel itself are damaged by an earthquake or the like It is a fact that is often happening.

On the other hand, in order to install an earthquake-proof device on an installation object such as a switchboard, the Korean Patent Registration No. 10-1045249 (issued on July 4, 2011) discloses a technique of a damper for earthquakes and an earthquake-proof system using the damper, It has the disadvantage that it can absorb the earthquake energy for the vertical damper but can not absorb the horizontal vibration energy. That is, there is a limitation in absorbing the earthquake energy applied in both the vertical direction and the horizontal direction.
