電気ヒューズ内の熱機械的ひずみ疲労を検出するための監視システムおよび方法

Document Type and Number:

Japanese Patent JP7213094

Kind Code:

B2

Abstract:

Systems and methods for detecting thermal-mechanical strain fatigue in an electrical fuse include a controller configured to monitor at least one fuse fatigue parameter over a period of time while the fuse is connected to an energized electrical power system, and based on the monitored at least one fuse fatigue parameter, the controller is further configured to determine at least one of a consumed service life of the fuse element or a service life remaining of the fuse element.
