DISTRIBUTION PANEL AND DISTRIBUTED POWER SUPPLY SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a distribution panel for securing high safety by preventing multipoint grounding and a distributed power supply system comprising the distribution panel.SOLUTION: A distributed power supply system 100 comprises a distribution panel 10 comprising an autonomous operation grounding electrode 20, linkage breaker 16, and autonomous grounding breaker 18. The autonomous operation grounding electrode 20 grounds a neutral line on the premises. The linkage breaker 16 opens/closes connection between a power grid 1 and a main circuit 2 on the premises. The autonomous grounding breaker 18 opens/closes connection between the autonomous operation grounding electrode 20 and the main circuit 2 on the premises. Exclusively opening/closing the linkage breaker 16 and autonomous grounding breaker 18 maintains a state of one point grounding whether the main circuit 2 on the premises is connected or disconnected to or from the power grid 1.
