摘要： The present invention relates to an air circuit breaker, in which a recess is formed on one side or each of both sides of each contact plate provided in an insulating cage so as to reduce a contact area between a movable contactor and the contact plate when the movable contactor and the contact plate are brought into contact with each other, thereby preventing a contact portion between the movable contactor and the contact plate from being melted due to heat generation.

摘要： An electric switch includes first and second stationary contacts, and a movable contact for making an electrical connection between the first and second stationary contacts. The movable contact is pivotally connected to the first stationary contact by a pivotal connection for allowing the movable contact to pivot with respect to the first stationary contact about a pivoting axis such that in an open position of the switch, the movable contact is disconnected from the second stationary contact, and in a closed position of the switch, the movable contact is in contact with the second stationary contact. The movable contact and the first stationary contact are arranged in a first angle with respect to each other in the open position of the switch, and in a second angle with respect to each other in the closed position of the switch, and the second angle is greater than the first angle.

摘要： An encapsulated medium voltage vacuum circuit interrupter includes a line terminal, a load terminal, a vacuum interrupter, an operating mechanism and an elongated, insulated, generally cylindrical encapsulating housing. The vacuum interrupter includes a vacuum envelope containing a fixed contact assembly and a movable contact assembly movable between a closed circuit position in electrical communication with the fixed contact assembly and an open circuit position spaced apart from the fixed contact assembly. The fixed contact assembly is electrically interconnected with the line terminal. A flexible conductor electrically connects the movable contact assembly with the load terminal. The operating mechanism moves the movable contact assembly between the closed circuit position and the open circuit position. The housing includes a first end supporting the line terminal and an opposite second end supporting the load terminal. The housing encloses the vacuum interrupter, the flexible conductor and the operating mechanism.

摘要： A switching apparatus wherein the life and the reliability of an electric contact are improved by fundamentally suppressing formation of black powder and activation of the surface of the contact by a chemical reaction. Microcapsules in which organic acid or organic acid precursor from which organic acid is produced as time passes is enclosed are placed into the internal space of an enclosed case so that organic compounds produced on and in the proximity of contact surfaces is oxidized with organic acid which escapes from the microcapsules and vaporized in the enclosed case without forming a film on the surfaces of the contacts to suppress activation of the surfaces of the contacts.
