Title:
ELECTRIC WIRE PROTECTION DEVICE
Document Type and Number:
Japanese Patent JP2018152991
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an electric wire protection device capable of protecting an electric wire appropriately.SOLUTION: An electric wire protection device includes a voltage adjustment section for supplying a load with the power supply side voltage while adjusting, and a control section having a temperature calculation part for calculating the temperature information Tw of an electric wire connecting the power supply and the load from the value of a current I flowing through the voltage adjustment section, and bringing the voltage adjustment section into a state for blocking the power supply and the load based on the temperature information. The temperature information is calculated from the temperature variation amount based on the current value and the predetermined initial value of temperature information. When sleep condition including a condition that the temperature information has a value of lower temperature side than the initial value is established, transition is made to sleep state, and the initial value Tini when the control section is reset from the sleep state (t15) is a value based on the convergence value of temperature when the electric wire is electrified with the maximum value of steady current.SELECTED DRAWING: Figure 4
