要約(英語): A bimetallic strip is a key component of thermal relays and molded-case circuit breakers, which are used to detect overcurrent faults in low voltage networks. Recently, a heat-insulated double-metallic (HIDM) strip was developed as an alternative for conventional bimetallic strips. It consists of two metallic strips bonded by a heat-insulated adhesive, and when an excessive current flows through the heater attached on one side of it, it deforms or bends due to the temperature difference. Because of its simplicity and low dependence on the ambient temperature, a high accuracy of current detection is expected. This paper shows that the performance of the HIDM strip can be improved by proper selection of the metal and design of its shape.
