In general, a switchboard refers to a device that constantly inserts and manages switches, instruments, relays, etc. for the operation or control of power plants and substations, and the operation of electric motors. It plays a role of safely protecting the above devices from external influences such as

As such, various devices installed inside the switchboard all share high voltage current, so it is desirable to use a switchboard case with durability and safety. there should be

Therefore, a shock-absorbing structure with seismic resistance is being developed by actively utilizing a material having its own elastic force, such as a spring, silicone, or rubber.

As an example, Laid-Open Patent Publication No. 10-2011-0036874 "Seismic-resistance device for switchgear using seismic spring" is published, and this technology has a housing installed on the bottom of the switchboard in a height-adjustable form, and in the inner space of the housing. A fixed plate inserted to support the ground is provided, and as the spring is interposed between the housing and the fixed plate, the spring exerts a cushioning action between the fixed plate and the housing, thereby mitigating the shaking of the ground due to earthquakes.
