PANELBOARD AND ITS REPAIR CONSTRUCTION METHOD AND METHOD FOR CONSTRUCTING POWER-LINE COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a repair construction method for a panelboard, easily conducting countermeasures against signal-leakage of a power-line communication to the panelboard and countermeasures against interference between groups holding the panelboard.

SOLUTION: The repair construction method for the panelboard 1 is used for adding a function suppressing the signal passage of the power-line communication to the panelboard 1 having a breaker 3 in the inside thereof. In the repair construction method for the panelboard 1, inductances 9 for filters for suppressing the signal passage of the power-line communication are configured by winding flexible magnetic sheets 12 mixing the fine powders of a magnetic material on electric circuits 7 for the panelboard 1.
