METHOD AND DEVICE FOR RELEASING CONDUCTOR SAFETY DEVICE INSIDE VEHICLE

摘要

PURPOSE: A method and a device are provided to work a safety device at the right time before breaking an important element using reserve volume of the conductor with the low cost. CONSTITUTION: A conductor(1) has a safety device(2) and the safety device arranges a current sensor(3) in a line. The current sensor detects current flowing in a wire or other electric parameter and an evaluating unit(4) processes current that is detected by the sensor. The evaluating unit uses or calculates release value according to the time or the various fixing release value for comparing with the measured current value, and then the first fixing release value forms the second release value according to the time. If the real measuring value is more than the second release value, a release unit(5) works so that the safety device is released and the conductor is intercepted.
