Description

(1) Technical field [0001] The invention relates to an instrument for detecting the technical performance of a fuse, in particular to a device for detecting breaking characteristics of a current-limiting fuse. (2) Background technology [0002] Most electrical fires are caused by circuit overload. In order to prevent circuit overload, anti-overload protection measures must be provided according to standard design. There are usually automatic overload switches, fuses, etc., and the most common is the fuse. Fuses are responsible for the safety of electrical appliances and electrical equipment, and have a wide range of applications. However, due to their simplicity, few people pay attention to them. As a result, the arbitrariness of illegal installation and non-installation has resulted in continuous electrical fire accidents. [0003] There are national standards for the identification of fuses, but the identification method is very complicated, and its various performance i...
