    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 discloses a contact module for circuit breaker. The contact module comprises: a base, a cover, an operation mechanism, three kinds of single-pole switches and a release mechanism. The cover is mounted on the base to form an accommodation space, the operation mechanism, the three kinds of single-pole switches and the release mechanism are disposed in the accommodation space. The operation mechanism is connected to one kind of the single-pole switch, the release mechanism is connected to the three kinds of the single-pole switches. All of the three kinds of single-pole switches are asymmetrical. Each kind of single-pole switch comprises a strong side and a weak side, for each kind of single-pole switch, a contact housing on the strong side is thick and is connected to a thick shaft, a contact housing on the weak side is thin and is connected to a thin shaft. A rotor component in each kind of single-pole switch only has a single contact spring and the single contact spring is mounted on the weak side. Rotation shafts of adjacent single-pole switches are connected by a linkage shaft so that the single-pole switches are connected, a strong side of one single-pole switch is connected to a weak side of another single-pole switch.

    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.

    摘要: A contact device includes a pair of fixed contactors fixed to one side of an insulation container with a predetermined space therebetween and having a columnar shape with a tip end contact surface protruding at lease inside the insulation container, and a movable contactor disposed to be capable of contacting with and separating from the pair of fixed contactors. Surfaces of the pair of fixed contactors facing the movable contactor are formed of annular peripheral walls having a concave part at a center thereof. An annular arc is formed between the annular peripheral wall and the movable contactor when the contact device is in an open state.
