    摘要: A power switching device including a fixed contact, a movable contact, an arc runner for transferring a leg of an electric arc to the outside of the fixed contact, a U-shaped fixed contactor electrically connected to the fixed contact, and a deionizing grid for extinguishing the arc. The side of the fixed contact is opposed to the side of the arc runner in three directions. At least the portion of the arc runner close to the fixed contact is kept away from the fixed contact and is physically separated therefrom by an electrically insulating medium. The arc runner is fixed and connected to a portion of the fixed contactor which is on the opposite side of the deionizing grid with respect to the fixed contact. Further, the runner extends so that it forms a continuous path along which the arc runs. Accordingly, after the arc has been transferred to the runner, it is urged toward the deionizing grid, thereby assuring continuous and smooth movement of the arc. Thus, a situation in which the arc is moved away from the grid resulting in incomplete extinction of the arc is prevented.

    摘要: A power switchgear is equipped with a stationary contact and contact-maker, a movable contact and contact-maker, a commutating electrode and an arc runner. The elements are constructed and arranged such that when the contacts open, the resultant arc will be quickly driven from the contacts to the commutating electrode and arc runner, to increase the life of the contacts and shorten the arcing time.

    摘要: A strip-shaped fusible member is disposed in a slit formed in an electrically insulating member to be not greater than 1 mm in width. Further a granulated electrically insulating material may be charged around the electrically insulating member within an enclosed housing. Alternatively, a plurality of electrically insulating members may alternate in intimate contact relationship fusible member to form a stack. Each fusible member is connected at both ends to two terminal blocks located on the opposite sides of the stack on those portions higher in level than that portion thereof sandwiched between the insulating members while its end portions are slackened.

    摘要: A circuit interrupter has a pair of contacts, a self-restoring type current limiting element and a first electromagnetic trip device serially interconnected. The current limiting element is connected across a parallel connected resistor and a second electromagnetic trip device. Both trip devices have a common magnetic circuit including a single stationary core and a single movable iron piece. The first trip device responds to a shortcircuiting current flowing through it to open the contacts but the second trip device is operative to open the contacts only after the current limiting element has performed the operation of limiting a shortcircuiting current.

A plurality of metal arc-extinguishing plates are arranged parallel to the surface of the stationary contact piece and at a predetermined distance from the commutation electrode, extending in the direction in which the movable contact piece is moved with respect to the stationary contact piece. A predetermined distance is maintained between the commutation electrode and the metal arc-extinguishing plates.
