Title:
アーク検出システム及び分電盤
Document Type and Number:
Japanese Patent JP7357202
Kind Code:
B2
Abstract:
To provide an arc detection system capable of detecting the presence or absence of arc fault in multiple branch circuits.SOLUTION: An arc detection system 100 includes an arc detection unit 33. The arc detection unit 33 detects the existence/absence of arc fault based on an AC voltage V1 generated between an AC power source 20 and multiple cable ways that electrically connect at least one load circuit. The arc detection unit 33 is provided integrally with a main switch 3 that is electrically connected between the AC power source 20 and at least one load circuit.SELECTED DRAWING: Figure 2
