摘要： A current limiting device includes first and second contact members, each contact member having, at a first end, contacts defining a contact pair; a contacting pressure is applied to said contact pair; and a cylindrical insulator cylindrically surrounding the contacts when the contacts are closed. The device is arranged such that at least one of the first and second contact members is rotatably supported at a second end. Also, an electrical path is defined through which currents flow in substantial opposition to the first and second contact members and in opposite directions to each other. The first ends of the first and second contact members are positioned within the space defined by the cylindrical insulator in the closed contact state. The contact of at least one of the rotatably supported contact members is positioned outside of the space defined by the cylindrical insulator when the contacts are open.

摘要： A switch includes a fixed contact having a first conductor portion connected to a terminal, a second conductor portion having a stationary contact, and a third conductor portion. The third conductor portion is disposed on the side of the other end of a moving contact to which a traveling contact is not mounted with respect to a position of the stationary contact, and on the side opposed to the terminal. The first conductor portion is disposed above a contact surface of contacts at a contact closing time, and is disposed below a contact surface of the traveling contact at a contact opening time. A position of the first conductor portion which can be surveyed from a surface of the traveling contact at an opening time of the contacts is coated with an insulator. Thereby, it is possible to provide an excellent current-limiting performance since an entire current path of the fixed contact generates electromagnetic force to stretch an arc on the side of the terminal, and since the arc is cooled by vapor generated from the insulator.
摘要翻译： 开关包括具有连接到端子的第一导体部分，具有固定触点的第二导体部分和第三导体部分的固定触点。 第三导体部分设置在相对于固定触点的位置并且在与端子相对的一侧上没有安装行进触点的可移动触点的另一端的侧面上。 第一导体部分在触点闭合时间处设置在触头的接触表面上方，并且在接触打开时间处设置在行进触点的接触表面下方。 在触点的打开时间可以从行进触点的表面测量的第一导体部分的位置涂覆有绝缘体。 因此，由于固定接点的整个电流路径产生电磁力以拉伸端子侧的电弧，并且由于电弧被从绝缘体产生的蒸汽冷却，所以可以提供优异的限流性能。

摘要： A switch comprising a switch case, contacts adapted to be opened and closed, an arc extinguishing chamber disposed in the vicinity of the contacts, and an arc extinguishing material capable of reducing the amount of metal particles and free carbons to be scattered from components disposed within the switch by an arc generated when the contacts are opened or closed or capable of insulating the metal particles and the free carbons to convert into an insulator, thereby inhibiting a decrease in arc resistance expected to occur upon the generation and extinction of the arc and a decrease in insulation resistance expected to occur within and around the arc extinguishing chamber and at inner wall surfaces of the switch case upon and after the extinction of the arc. The switch according to the present invention is applicable to a switch expected to generate an arc upon interruption of electric current flowing therethrough such as a circuit breaker, current-limiting device or electromagnetic contactor and is capable of immediately extinguishing the arc and inhibiting the decrease in insulation resistance within and around the arc extinguishing chamber and at inner wall surfaces of the switch case.
