Document Type and Number:
Japanese Patent JP2015070686
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a distribution board with an electric outlet capable of improving communication performance via a communication apparatus.SOLUTION: A distribution board 1 is a distribution board capable of being connected to a communication apparatus 20 which can perform communication with a smart meter 100 via a power line 90 using a predetermined frequency bandwidth. The distribution board 1 includes: a main circuit breaker 12; and an electric outlet 18 which is connected to a power line at the secondary side of the main circuit breaker 12. The distribution board 1 also includes plural branch breakers 14 which are connected to the power line at the secondary side of the main circuit breaker 12. The distribution board 1 also includes an impedance upper 17 that increases the impedance of the predetermined frequency bandwidth at the branch breakers 14 side as viewed from the electric outlet 18 to be higher than the impedance of the predetermined frequency bandwidth at the main circuit breaker 12 side as viewed from the electric outlet 18, which is disposed between the connection section of the electric outlet 18 and the connection section of the branch breakers 14 in the power line at the secondary side.
