Definitions
- the invention relates to a switching system with a first contact and with a second contact, which are mutually movable in an opening direction.
- the switching system is intended in particular for the low-voltage range, preferably for a relay or for a contactor, wherein the voltages to be switched are up to 1500 V in DC operation and 1000 V in AC operation.
- a circuit breaker for DC and AC with two contact points is known. Between the contact points a contact bridge is arranged, which is spent in a triggering of the circuit breaker in the transverse direction. The resulting arcing at the two contact points are driven by means of a blowing device.
- One of the two arcs is in this case blown to an edge region of the contact bridge, whereas one of the bases of the other arc is brought by means of baffles substantially in electrical contact with the two contact points.
- the two contact points are electrically short-circuited by means of the second arc and the second arc assumes the electrical function of the contact bridge in the closed state.
- the second arc is thus connected in parallel to the contact bridge.
- the first of the two arcs goes out.
- the remaining arc is driven by means of another blowing device in a quenching chamber and there extinguished.
- the invention has for its object to provide a particularly suitable switching system with a first contact, with a second contact, which are movable in an opening direction to each other, and a circuit breaker with the switching system, wherein an arc forming between the two contacts is erased relatively efficiently , and wherein the weight and the size are reduced in particular.
- the switching system has a first contact and a second contact, which are electrically connected in series and serve to conduct current within the switching system.
- the two contacts are mutually movable in an opening direction.
- the first contact is stationary, so it is held stationary by means of further elements of the switching system.
- the second contact for example, by means of a hinge, such as a film hinge or the like, movably mounted.
- the first contact is a fixed contact and the second contact is a moving contact.
- both contacts are movably disposed within the switching system.
- the first contact is movably supported by means of a hinge.
- at least one of the contacts can be moved in a transverse direction.
- the two contacts are preferably mechanically directly to each other and are spaced apart in the non-conductive state.
- the contacts are spent to each other in the opening direction.
- the opening direction is understood to be the direction in which the second contact is moved with respect to the first contact in order to transfer the switching system from the conducting to the non-conducting state.
- the second contact is transversely spent with respect to the first contact.
- the opening direction denotes the direction parallel to the transverse line.
- the second contact is rotated with respect to the first contact, in particular by means of a hinge or a fixed axis. In this case, the opening direction is tangential with respect to the rotation axis.

- a heat exchange takes place between the plasma and the comparatively cool extinguishing element. Due to the large contact area between the plasma and the extinguishing element, the heat exchange is comparatively efficient, so that the plasma is relatively strongly cooled.
- the cooling of the plasma and the associated depletion of energy cause an increase in the elec- electric field strength of the arc. Between the first and second contact, this leads to a strong and rapid increase in the arc voltage.
- the arc voltage reaches or exceeds the value of the voltage applied to the switching system electrical voltage, this leads to a limitation and reduction of the current flow up to its interruption.
- the arc is comparatively efficiently cooled and limited in its cross-sectional area and thus erased relatively quickly, and consequently the switching system is placed in a non-conducting state.
- the porous material Due to the use of the porous material, it is possible to produce a comparatively lightweight and compact switching system. In addition, the production of a porous material is easier and faster than, for example, the arrangement of quenching plates.
