Embodiment Construction

[0033] The same reference numerals are used for identical or identically acting elements of the invention. The illustrated embodiments represent only examples of how the device according to the invention and the method according to the invention can be designed and do not represent definitive restrictions.

[0034] figure 1 and 2 Shown is an electrical contactor 1 according to the invention having a stator 2 and an armature 3 movable relative thereto, which is connected to at least one contact area 4a or 4b, preferably two contact areas 4a and 4b . These contact areas 4a and 4b can be connected to preferably fixed counter contact areas 5a and 5b respectively. Furthermore, a propulsion device 6 in the form of a flywheel 7 is connected to the armature 3 .

[0035]The stator 2 positioned laterally to the armature 3 is fixedly connected to the housing 8 of the electrical contactor 1 . Furthermore, the activation and supply of the stator 2 are not shown here, which can include...

Abstract

Disclosed is an electric contactor, in particular to be used in roadways, with the stator and an armature, the armature being connected with a contact region and being movable, during a switching-on operation and / or a switching-off operation of the contactor, from a first to a second position, the contact region being connected in at least one of these positions with a counter-contact region for closing an electric circuit, wherein a pushing device is connected with the armature which is rotational relative to the armature, wherein the pushing device at least temporarily pushes the armature supportively in the movement from the first to the second position of the switching-on and / or switching-off operation.

Description

technical field [0001] The invention relates to an electrical contactor according to the invention. Background technique [0002] Electrical contactors are known, in particular from the field of railway construction, which place the highest demands on their construction with regard to their wear resistance. The contact areas of the high power contactors used therein are especially exposed to enormous stresses. Due to the high current to be connected, especially in the Currents in the kA range result in high loads. In this case, the contact between the contacts is already caused before the contact area is placed on the mating contact area (as in the making phase) and also after the contact area is separated from the mating contact area (as in the breaking phase). Charge transfer, which is manifested by the formation of electric arcs. Therefore, very high thermal loads act on the corresponding contact regions during these switching phases. The longer and more frequently t...
