    摘要: Electronic driving components sized to drive contactors of a determined power class are generally used. The object of the invention is to create a process and circuitry which allows contactors of different power classes to be driven by a single driving component. The user selects on a scale the switching position corresponding to the contactor to be driven. A reference voltage proportional to the magnitude of the starting current of the respective contactor is thus selected. An automatic regulation keeps constant the starting current during the starting time of the contactor. For that purpose, a measurement voltage proportional to the magnitude of the starting system and dropping across a measuring resistor is supplied to a first input of a comparator, a reference voltage which may be selected by a coding switch (6) being applied to the second input of the comparator. The output of the comparator co-operates with a switching element which switches the starting current. This circuitry may be mounted upstream of existing contactors, in particular on a top hat rail.

    摘要: An electromagnetic contact device performs on-off operations for opening and closing an electrical path, without causing the hunting phenomenon between the two contact points in the device not only during closure of a fixed contact point and a movable contact point therein, but also when a voltage to be applied to an operating coil has lowered. An operating coil generates a predetermined energizing force in combination with a fixed iron core, a starting circuit rectifies a large capacity electric current from an AC power source when attracting a movable iron core and supplies the rectified current to the operating coil. A holding circuit supplies the large capacity current from the AC power source to the operating coil through means of converting the large capacity current to a small capacity current at the time of holding the movable iron core. A change-over switch changes the energizing current supply source for the operating coil from the starting circuit to the holding circuit, the change-over switch having a hysteresis characteristic such that it performs its off-operation after closure of both contact points when the main circuit is closed, and performs its on-operation after separation of both contact points when the voltage to be applied to the operating coil has been lowered.

    摘要: The magnetic valve with electronic control for increasing the attractive output has an energizing coil (AE), which is supplied in the attracting phase with an increased energizing current via a closed switch (T2). In the maintenance phase, the energizing coil (AE) is supplied with a maintenance current, via a compensating resistor (RV) and with the switch (T2) opened, which is lower than the energizing current. For the purpose of controlling the switch (T2), a timing circuit is provided which includes a resistor (R2) and a capacitor (C2). The magnetic valve is selectively drivable with alternating current or direct current. A portion of the energizing coil (AE) is made up of the compensating resistor (RV), which is embodied as a resistor wire and wound up on the energizing coil (AE).

    摘要: A circuit arrangement operates a heavy-duty electrical equipment including an electrical relaying device having a relay coil and a set of first and second relay contacts. The first relay contacts are connected in a circuit that supplies a large amount of current to the electrical equipment. The relay coil is connected to be energized with a small amount of current in response to the closure of a normally open switch and held energized in response to the closure of the second relay contacts. The normally open switch and the second relay contacts form a closed low impedance circuit which supplies an arc current pulse to the second relay contacts during the time when the normally open switch is held closed, whereby fragmentary objects or dust collected between the second contacts is removed as the first and second contacts chatter during a closing.

    摘要: A method of increasing speed of an electro-mechanical relay provides an electro-mechanical relay having a coil and at least one contact. A first resistor and a second resistor are each in series with the coil, with the second resistor being in parallel with a first switch. A voltage is provided to the first switch, with the first switch being ON, thereby shorting out the second resistor and providing a first current through the first resistor and to the coil, to move the contact to a closed position. After a certain amount of time, the first switch is turned OFF so that a second current is provided through the first and second resistors and to the coil, maintaining the contact in the closed position.
