Pressing the upper side of the GIS base 2000 in the downward direction, the spring guide 2230 is positioned in the inner space 2221 of the spring 2220 in a direction in which the spring 2220 is horizontal to the ground. It has a structure that guides it to move in a direction perpendicular to the ground while its position is fixed, and when absorbing vibration caused by an earthquake, the spring 2220 moves in a direction perpendicular to the ground along the spring guide 2230. Vibration can be absorbed by moving to .

In this way, in one embodiment of the present invention, the structure of the seismic module 2200 reduces vibration caused by an earthquake when an earthquake occurs and prevents the vibration from being transmitted to the fixed part 1000 including the busbar tank 1100. It can be effective.
