Abstract
Provided by the present invention is a current overload protection apparatus. The apparatus comprises a current measuring device and a control module; the current measuring device is used to measure a current value on a current path; the control module is electrically connected to the current measuring device, and stores current threshold data; the current threshold data comprises a plurality of time intervals respectively corresponding to disconnection threshold values; the earlier the time corresponding to a plurality of time intervals, the larger the disconnection threshold value corresponding thereto; and the control module is used to receive and collect current signals within a specified time length so as to calculate the current value of the current path, and determine whether the current value is greater than or equal to the disconnection threshold values, and if so, then an overload protection step is performed to protect the load from current overload.
