POWER DISTRIBUTION SYSTEM AND DISTRIBUTION BOARD SYSTEM

To provide a power distribution system and a distribution board system capable of supplying power more flexibly in emergency or the like.SOLUTION: A power distribution system 1 includes an earthquake detection unit 231 and a switching board 2. The earthquake detection unit 231 detects occurrence of an earthquake. The switching board 2 switches a power supply source to at least a part of a circuit 4 between multiple input terminals 21, 22 including the first input terminal 21 and the second input terminal 22. The first input terminal 21 is electrically connected to a regular power supply. The second input terminal 22 is electrically connected to a backup power supply 6. The switching board 2 is configured so as to, when the earthquake detection unit 231 detects the occurrence of the earthquake, switch the power supply source for at least the part of the circuit 4 from the first input terminal 21 to the second input terminal 22.SELECTED DRAWING: Figure 2 【課題】非常時等における電力の供給をより柔軟に行うことができる配電システム及び分電盤システムを提供する。【解決手段】配電システム１は、地震検出部２３１と、切替盤２と、を備える。地震検出部２３１は、地震の発生の有無を検出する。切替盤２は、第１入力端子２１及び第２入力端子２２を含む複数の入力端子２１，２２の間で、少なくとも一部の回路４への電力の供給元を切り替える。第１入力端子２１は、常用電源に電気的に接続される。第２入力端子２２は、バックアップ電源６に電気的に接続される。切替盤２は、地震検出部２３１での地震の発生の検出時に、少なくとも一部の回路４への電力の供給元を、第１入力端子２１から第２入力端子２２に切り替える。【選択図】図２
