【発明の名称】アーク故障検出回路遮断器システム
Document Type and Number:
Japanese Patent JP2003536353
Kind Code:
A
Abstract:
An arc-fault detecting circuit-breaker system includes a normally closed line circuit breaker in series with a protected electrical circuit element whose current flow is to be interrupted upon the occurrence of an arc fault. A detector senses the rate of change with time of the current flow in the protected electrical circuit element. A silicon-controlled rectifier has a gate of the silicon-controlled rectifier in electrical communication with a detector output signal of the detector. The silicon-controlled rectifier shorts the current flow in the protected electrical circuit element in the event that the detector output signals that the rate of change of current with time in the protected electrical circuit element is in excess of a permitted maximum rate-of-change value, thereby activating the line circuit breaker.
