The present invention relates to a power distribution board with an earthquake alarm system, and specifically, to a power distribution board with an earthquake alarm system capable of generating an alarm by detecting external impacts such as an earthquake, on power distributor materials including a power distribution board and a bus bar, etc. The present invention comprises: a first object subject to combination installed on the power distribution board; a second object subject to combination installed on the power distribution board and combined to the first object subject to combination; a connection member which combines the first and the second objects subject to combination; an applied pressure detection member with a piezo sensor detecting pressure applied onto the first and the second objects subject to combination, through the connection member; a wireless transmission unit mounted on the applied pressure detection member and transmitting the pressure detected from the piezo sensor as a wireless signal; and an alarm wirelessly connected to the wireless transmission unit and generating an alarm if the pressure transmitted from the wireless transmission unit is below a pre-set value. If a change amount of the applied pressure is detected and the connection member is loosened by an external vibration or an impact, the piezo sensor transmits this to the wireless transmission unit. |
