| Abstract(in English) | Each automotive manufacturer is making examination for bringing up of the nominal capacity of automotive buttery from 14 V to 42 V in order to meet the increase of the rate of fuel consumption and large electrification of the electric apparatus. It is known, however, that when the voltage of power source is made 42 V, it is very difficult to cut off the arc discharge that is generated on breaking for the single-break contact point, the basic structure of the traditional relay. And, for a method to solve the problem, a double-break contact mechanism which is able to widen the actual contact gap is proposed. We obtained basic knowledge of each material this time conducting endurance tests on widely-known Ag based contact materials under typical loads. As a result, Ag showed an outstanding durability under resistive load and inductive load. And, with inductive load, the AgZnO contact material showed an outstanding durability and arc cutoff capacity. |
