Definitions

  • the invention relates to an electrical contactor according to the preamble of independent claim 1.
  • a contactor comprises a housing, at least two fixed main contacts and a main contact bridge, at least two fixed side contacts and a secondary contact bridge, both the main contacts, the side contacts as well as the contact bridges in the housing are arranged.
  • an electrical contactor comprises an armature provided for actuating the main contact bridges and auxiliary contact bridges. In a first switching position, both the main contacts and the secondary contacts are opened, wherein the armature is in a starting position. In a second switching position, the secondary contacts are closed and the main contacts open. The anchor is in an intermediate position.
  • both the secondary contacts and the main contacts are closed, wherein the armature is in an end position.
  • the contactor further comprises at least one electrically energizable coil for an electromagnetic drive of the armature, wherein a magnetic force acting on the armature by the magnetic field generated by the coil causes the drive of the armature.
  • a coil yoke is provided which forms a magnetic return.
  • such a contactor also comprises means for resetting the armature to the starting position. A restoring force acting on the armature by the means is opposite to the magnetic force generated by the magnetic field and, moreover, greater in the end position of the armature than in the intermediate position.
  • Such contactors are commonly used to pre-charge via the side contacts, such as a capacitor, before the main contacts are closed. This is necessary, for example, if a DC voltage is switched to a converter or an inverter via a contactor. At the entrance of such a converter or inverter is usually a large capacitor. If the DC voltage is switched directly to the capacitor via the main contacts, practically a short-circuit current flows for a certain time, namely until a resistance is generated by the charge of the capacitor. The period of time in which this high short-circuit current flows depends on the capacitance of the capacitor and the internal resistance of the source and the resistance of the supply lines. The high current is detrimental to the main contacts and can lead to welding of the main contacts. In any case, the life is reduced.
  • a contactor of the type mentioned is known from DE 31 05 117 A1.
  • the secondary contacts are designed as leading contacts. This means that when switching on by the movement of the armature from the initial position to the end position, the side contacts are closed first, so that, for example, a capacitor can be charged for a short time on the side contacts and a resistor connected to the side contacts. However, the armature is immediately further moved by the coil driving it into the end position, so that a short time after closing the secondary contacts and the main contacts are closed.
  • a similar contactor is also known from DE 103 15 243 B3. In contrast to the known from DE 31 05 117 A1 contactor here, however, the side contacts and then only the main contacts are opened when the switch-off.
  • the contactors known from the prior art have in common that the time period in which the secondary contacts are already closed before the main contacts are closed, can not be varied.
  • the anchor which initially closes the side contacts and then the main contacts on its way from an exit position to the end position, so to speak, switches from the initial position to the end position.
  • An intermediate position of the armature, in which only the secondary contacts are closed, can not be maintained in a controlled manner over a longer period of time.
  • Another disadvantage of known from the prior art contactors of the type mentioned is that the electromagnetic coil for driving the armature must be relatively large dimensions to move the armature from the starting position to the end position. That the power consumption of the electromagnetic coil for driving the armature is relatively large, so that known from the prior art contactors have a large power loss, even if the coil holds the armature only in the final position.
  • Object of the present invention is therefore to provide for a contactor of the type mentioned above a way to keep the anchor controlled in the intermediate position, in which only the side contacts are closed. It is another object of the present invention to provide a contactor of the type mentioned above with significantly reduced power loss.
  • the object is achieved according to the invention by the features of claim 1. Accordingly, there is a solution according to the invention before the task, if for the electromagnetic drive of the armature, a pre-charge coil and an additional or independent of the pre-charge coil energizable suit coil are provided, the Spulenjoch such a is ordered that the magnetic force acting on the armature by the magnetic field generated by the precharge coil at the same energizing the Vorladespule in the end position of the armature is greater than in the intermediate position, said magnetic force in the intermediate position of the armature of the restoring force corresponds and in the end position of the Anchor is greater than the restoring force, and wherein the precharging coil is provided to move the armature from the starting position to the intermediate position and to hold in the end position, and further the tightening coil is provided to move the armature from the intermediate position to the end position ,
  • the invention offers the advantage that the armature can be kept controlled in the intermediate position, in which only the secondary contacts are not closed but the main contacts. Thus, it is possible to determine via a suitable measuring electronics, for example, whether there is a short circuit in the circuit closed by the secondary contacts. In the case of a short circuit, the further switch-on can be interrupted.
  • Another advantage of the present invention is that the armature in the end position, in which both the side contacts and the main contacts are closed, can be held by the low-power precharge coil, so that the power loss of the contactor is relatively low. When switching on the suit coil must be switched on only for a short time.
  • the tightening coil is usually designed to be more powerful, but is only operated for a short time.
  • the tightening coil of the precharging coil for driving the armature is switched from the intermediate position to the end position.
  • the tension coil would have to be designed to be more powerful.
  • the precharging coil and the attraction coil are arranged concentrically with one another.
  • the magnetic field generated by the precharging coil can be amplified by the suiting coil in an optimum manner.
  • Precharging coil and tightening coil preferably surround at least part of the armature. So a very large magnetic force can be exerted on the anchor. In addition, this arrangement allows a space-saving design.
  • the pre-charge coil and the attraction coil are wound on top of each other, wherein the attraction coil is the outer winding represents.
  • the resistance of the tension coil is smaller than the resistance of the precharge coil, the power of the tension coil and thus the magnetic force generated by the tension coil on the armature is so large that a faster and safe switch-on can be guaranteed.
  • the suit coil is wound from a thicker wire than the precharge coil.
  • the means for returning the armature to the starting position comprise a first spring, which is arranged between a first spring stop of the armature and a second spring stop connected to the housing and in any position of the armature between the starting position and the End position exerts a restoring force on the anchor.
  • the first spring ensures that the contactor is switched off as soon as the power supply to the coils is interrupted.
  • the means for returning the armature to the starting position further comprise a second spring, which is shorter than the first spring and is also disposed between the first spring stop and the second spring stop. The second spring exerts no restoring force on the armature when the armature is between the starting position and a position near the intermediate position.
  • the second spring is also harder than the first spring.
  • the first spring and the second spring are designed as spiral springs and arranged concentrically to one another. This allows a simple construction of the contactor according to the invention.
  • further electrical resistances are connected to terminals of the auxiliary contacts in order to limit the current intensity in a closed circuit via the auxiliary contacts.
  • the resistors can be integrated into the housing of the contactor. It is also possible to connect the resistors together with the contactor in a circuit. The provision of the resistors allows, for example, the precharging of a capacitor connected to the contactor.
  • an electronics for switching on and off of Vorladespule and suit coil and for measuring and monitoring a current flowing through the secondary contacts current is also provided.
  • the electronics are such that the tightening coil, if the current measured during the switch-on in the second switching position by the electronics falls below a first threshold, is switched by the electronics for a certain period of Vorladespule, so that the anchor from the intermediate position in the End position is moved, wherein the precharging coil, when the current measured by the electronics in the second switching position exceeds a second threshold for a certain period of time, is switched off by the electronics, so that the armature is moved by the restoring force to the starting position.
  • the electronics thus allows the detection of a short circuit in the circuit switched by the contactor and prevents the main contacts are closed in the presence of a short circuit.
  • main contacts and secondary contacts are arranged substantially side by side in a plane, so that it is aligned perpendicular to the direction of movement of the armature. This allows an extremely compact design of the contactor.
  • the contactor furthermore comprises a contact bridge carrier, on which the main contact bridges and auxiliary contact bridges are arranged, wherein the contact bridge carrier is connected to the armature.
  • the main contact bridges and the sub-contact bridges are spring-mounted on the contact bridge carrier by means of contact pressure springs.
  • the contact pressure springs By the contact pressure springs, the main contact bridges are pressed in the end position of the armature against the fixed main contacts, as well as the side contact bridges in the intermediate position and end position of the armature against the fixed side contacts.
  • the corresponding contacts are thereby firmly and securely closed in the respective position of the armature, so that an opening of the contacts is prevented by external mechanical loads such as vibrations occurring during operation of a vehicle.
  • the contact pressure springs of the secondary contact bridges are preferably longer than the contact pressure springs of the main contact bridges, wherein the distance between secondary contacts and secondary contact bridges in the first switching position is greater than the distance between main contacts and main contact bridges.
  • the arc quenching device preferably comprises a quenching chamber with a plurality of lamellae-like quenching plates.
  • the effect of the arc quenching device can be improved if the quenching chamber is filled with a protective gas.
