摘要： A system may include a relay device. The relay device may include an armature that moves between a first position that electrically couples a first contact to a second contact and a second position that electrically uncouples the first contact from the second contact. The relay device may also include a relay coil that receives a voltage configured to magnetize a relay coil, thereby causing the armature to move from the first position to the second position. The system also includes a control system that receives an indication that the armature is in the second position and sends a signal to an actuator in response to receiving the indication. The signal causes an arm associated with the actuator to move the armature to achieve a gap distance between the first contact and the second contact.

摘要： A contactor includes a housing and first and second fixed contacts coupling to the housing having mating ends received in the cavity of the housing and terminating ends outside of the housing. A movable contact is movable within the cavity between a mated position and an unmated position that engages the mating end of the second fixed contact in the mated position and is separated from the second fixed contact in the unmated position. A flexible busbar is coupled to the first mating end and coupled to the movable contact. The flexible busbar electrically connects the first fixed contact and the movable contact in both the mated position and the unmated position. A coil assembly in the cavity operates to move the movable contact between the unmated position and the mating position.

摘要： An actuating device for a vacuum switching tube has a connecting element which can be connected to an electric contact of the vacuum switching tube, an electromagnetic actuating device for displacing the connecting element between a first and a second position, and a retaining yoke, relative to which the connecting element can be displaced and has a first magnetic element. The first magnetic element generates a first and a second magnetic circuit in the retaining yoke. The actuating device further has a ferromagnetic retaining anchor, which is arranged on the connecting element. The retaining anchor is located in the first position of the connecting element in the first magnetic circuit and in the second position of the connecting element in the second magnetic circuit. The connecting element is held in the first and in the second position by a respective magnetic force between the retaining yoke and the retaining anchor.

摘要： According to an electromagnetic switch of the present invention, a crossbar operating in conjunction with a movable core slides in response to magnetization or demagnetization of an operating coil to cause attraction or separation between a fixed contact point and a movable contact point on the supply-side and between a fixed contact point and a movable contact point on the load-side. The electromagnetic switch further includes a first crossbar sliding part and a second crossbar sliding part, as well as a first casing sliding part and a second casing sliding part that allow the first and second crossbar sliding parts to slide. A contact between the first casing sliding part and the first crossbar sliding part or between the second casing sliding part and the second crossbar sliding part causes the crossbar on the side of the movable core to be tilted in a direction opposite to the direction of gravity with respect to the horizontal.

摘要： A relay circuit and a method for performing a self-test. The relay circuit has four relays, each relay having a first forcibly guided contact and a second forcibly guided contact. The four relays are arranged in a first and a second pair of two in series connected first forcibly guided contacts. The first and second relay pair are arranged in parallel between a power supply connection and a load connection for switching a power supply to a load through the first forcibly guided contacts. Such a relay circuit enables supplying power via one of the relay pairs, while cutting power via the other relay pair, which facilitates testing of the relay pair which has cut power without interrupting the process supervised by the Safety Instrumented System which the relay circuit forms part of.

摘要： A method is disclosed for testing a latching solenoid of a switch and a testing device for carrying out the method is disclosed. The switch includes a switching contact, formed by contact elements mechanically separated from one another when the switching contact is open; an electronic trip unit, to respectively monitor the current passing via the contact elements and test whether a current-dependent tripping condition is satisfied; and an actuator, to separate contact elements after actuation, the trip unit actuating the actuator via the latching solenoid when the tripping condition is satisfied; and an electrical energy store, to charge to a voltage before the tripping and to be discharged via the latching solenoid. After a period of time after the tripping, the voltage of the energy store is compared with a reference value and a fault signal is output if the voltage of the energy store is above the reference.
