摘要： One embodiment describes an operating coil driver circuitry, which includes a control circuitry that outputs a trigger signal and a reference voltage; an operational amplifier that compares the reference voltage to a node voltage, in which the node voltage is directly related to current flowing through an operating coil of a switching device and the operational amplifier outputs a logic high signal when the node voltage is higher than the reference voltage and outputs a logic low signal when the node voltage is lower than the reference voltage; and a flip-flop that outputs a pulse-width modulated signal to instruct a switch to supply a desired current to the operating coil based at least in part on the trigger signal and the signal output by the operational amplifier.

摘要： In the electromagnetic operating device, the driving power supply is composed of two types of power supplies: a capacitor power supply serving as a power supply which is for performing opening/closing operation in a normal time with respect to the vacuum valve; and a DC power supply which is for performing opening/closing operation in an emergency. The capacitor power supply which is for performing opening/closing operation in the normal time includes: capacitors that store electric power to be supplied to the electromagnetic coil; and a control board which controls a current to be supplied from the capacitors to the electromagnetic coil in response to an open-contact or close-contact command to the vacuum valve. Then, the DC power supply which is for performing opening/closing operation in the emergency is to directly supply DC electric power to the electromagnetic coil.

摘要： An electromagnetic contactor has a contact device having a pair of fixed contacts and a movable contact; and an electromagnet unit including an exciting coil driving a movable plunger connected through a connecting shaft. The contact device is configured such that L-shaped portions have a contact portion formed in the pair of fixed contacts fixed maintaining a predetermined interval, and two ends of the movable contact are disposed to be capable of contacting to and separating from the contact portions of the L-shaped portion on a side opposite to that of the electromagnet unit. The electromagnet unit includes a magnetic yoke enclosing a plunger drive portion, a movable plunger having a leading end protruding through an aperture formed in the magnetic yoke and urged by a return spring, and a ring-form permanent magnet magnetized in a movable direction of the movable plunger and fixed to enclose a peripheral flange portion.

摘要： An electromagnetic contactor includes a housing assembly that may be adapted for one, two, three or four poles. An armature is affixed to a contact carrier either by a flat leaf spring that passes through a slot in a laminated armature or by a press fit of a solid armature into the contact carrier. In one embodiment of the invention, a housing assembly snaps into a base to permit a maximum amount of automatic asssembly and a minimum number of components. These components include a base, a magnet assembly having at least one shading coil, a formed coil assembly, two symmetrically disposed springs to return a contact carrier to a neutral position when the coil is de-energized, an armature to complete the magnetic circuit that is attached to the contact carrier, a contact block that supports terminals and stationary contacts, and a contact carrier that carries one or more moving contacts into engagement with the fixed contacts. A coil spring for each contact applies a force when the electromagnet is energized to draw the removable contacts to the fixed contacts to close an electric circuit. A magnet clip secures the magnet assembly by latching in place without screws or rivets. In an alternate embodiment, a molded cantilever supports a coil assembly under spring tension.

摘要： A relay and a relay-adder combination incorporating a constant force actuating arrangement allowing for the use of the same coil in both configurations whereby a reaction force which is encountered in the actuation of the relay per se is bypassed in the actuation of the relay-adder combination and is replaced by the force which is encountered in the actuation of the adder and which is equal to the reaction force.
