    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: A circuit-breaker includes a fluid-tight cutout chamber in which are disposed a fixed contact as well as a sliding movable contact and which encloses a dielectric in the liquid state kept under pressure. The movable contact is brought and kept selectively against the fixed contact by releasable disconnecting means, in opposition to ever-present elastic disconnecting means tending to separate the two contacts and comprising hydraulic elastic means responding only to the volumetric elasticity of the compressed liquid in the circuit-breaker. The dielectric in the liquid state is preferably a compressible liquid having a compressibility at least ten times greater than that of oil and may be a liquified gas dielectric.

    摘要: The present disclosure provides controllers for power distribution network circuit interrupting devices and provides electronic control circuits for inclusion in such controllers. The electronic control circuit has a boost circuit, a capacitor storage unit and a pulse width modulator control circuit. The boost circuit boosts an input voltage to a value to supply sufficient energy to a protective relay solenoid to energize the solenoid. The capacitor storage unit stores the boosted voltage from the boost circuit. The pulse width modulator control circuit is responsive to a control and enable circuit to selectively enable energy from the capacitor to energize the one or more protective relays in power distribution system circuit interrupting device.

    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: A device for medium or high voltage switching element gear, the device having: a switching element for connecting two conductors: and a driving rod for operating the switch, wherein the driving rod comprises at least a surface layer of an electrically high resistance material. The electrically high resistance material ensures that a small current will flow through the material due to the present electrical field. This small current will cause a heating of the driving rod, such that condensation is reduced or prevented.

    摘要: An electromagnetic contactor includes a fixed contact portion, a movable contact portion disposed facing the fixed contact portion to contact to and separate from the fixed contact portion, and an arc extinguishing receptacle forming an arc extinguishing chamber housing the fixed contact portion and movable contact portion. Among contact surfaces of the movable contact portion and fixed contact portion facing each other, at least an opposing distance between a contact end portion of the fixed contact portion and a contact end portion of the movable contact portion positioned in a moving direction of an arc generated when separating the movable contact portion from the fixed contact portion is set to increase with increasing proximity to end surfaces on contact end portion sides.
