Definitions

the invention relates to a circuit breaker or also circuit breakers with a fixed contact and with a for establishing a switchable electrical connection two leads against this pivotable moving contact as well as with a blow coil for magnetic blowing resulting electrical when the contacts are separated Arc.
the switch contacts are usually on the side an extinguishing device, in particular an extinguishing chamber, intended.
the arc is often a cross to Arcing path exposed magnetic field.
a Lorentz force designated force exerted this towards the extinguishing device accelerated.
Such a means of a magnetic field forced migration of the arc referred to as magnetic blowing.
the invention has for its object a circuit breaker with a direction independent of the current flow and particularly effective magnetic blowing of a electric arc.
the invention is based on the consideration that a magnetic Blowing in an all-current circuit breaker is particularly effective when the direction of the magnetic field changes always with the current flow direction within the Arc changes. It uses the experience that such current-dependent magnetic field change advantageously by means of a Blow coil is achieved. This could be an improvement compared to a conventional blow coil, if the blow coil is only operated with an existing arc, i.e. flowed through by electricity. To everyone else At times, however, a current flow through the blow coil should be prevented to be an unnecessary sales revenue and thus to prevent undesirable heat generation. As is known the effect described is achieved when the blow coil is contacted by means of the arc. The arc acts as a switch that only turns the blow coil switches on if the arc is present.
this is with the blow coil connected contact element in the form of a catching shoe, which at least the moving contact in its open position surrounds laterally with respect to the arc gap.
the Moving contact thus dips into its open position Catch shoe, the arc from the moving contact to the Catch shoe jumps over and turns on the blow field.
the contact element is advantageously connected to a Provide permanent magnets, the one to the arc path approximately generates a vertical magnetic field and thus the arc in Deflects the direction of the contact element. That way skipping the arc on the contact element considerably accelerates.
the circuit breaker includes in Appropriate design two tracks that the arc lead from the area of the contacts to an arcing chamber.
the area formed between the runners is as Expansion area of the arc.
this closes a first track electrically conductive to the contact element on.
the electrical connection of the first track to the contact element encourages the arc to jump over from the contact element to the running rail.
the first track is only an alternative except for an insulation distance to the contact element introduced and via a parallel to the blow coil Line connected to the corresponding supply line. On this way the blow coil is only turned on the arc from the contact element to the running rails float. In this version, the current flow through the Blow coil interrupted as soon as the arc hits the running rails skipped. A heating of the blow coil through the electrical power implemented in it further reduced. The blow coil can be particularly space-saving will be realized.
circuit breaker 1 shows a partial circuit breaker in a partial view (Circuit breaker) 1, which has two leads 2 and 3 in one Circuit not shown is arranged.
the supply line 2 is via a contact bracket 4 with a fixed contact 5 electrically connected.
the feed line 3 is over Conductors 6 and 7 electrically connected to a contact arm 8, which carries a moving contact 9 at the end.
the contact arm 8 is pivotably mounted about an axis of rotation 10, that in the closed position, not shown, of the circuit breaker 1 the moving contact 9 on the fixed contact 5 rests.
the circuit in this case is over the Lead 2, the contact bracket 4, the fixed contact 5, the moving contact 9, the contact arm 8, the conductors 7 and 6 and the Supply line 3 closed.
the circuit breaker 1 is shown with an only hint Trigger 11 provided that when a predetermined occurs Trigger condition a mechanical impulse to the Contact arm 8 and a switch lock, not shown delivers.
a short-circuit current for example, can be used as the trigger condition be fixed within the circuit.
the mechanical output from the trigger 11 to the contact arm 8 Impulse is the contact arm 8 in the according to FIG. 1 shown open position pivoted.
this Pivoting of the contact arm 8 which is known in itself Can also be done manually, the fixed contact 5 and the moving contact 9 separated from each other.
the moving contact 9 is in its open position within a catching shoe 13 arranged.
the catching shoe 13 is essentially formed as a hollow cuboid from a conductive material.
the catching shoe 13 is on a fixed contact 5 facing side surface 14 and on one of the axis of rotation 10 of the contact arm 8 facing side surface 15 open, so that the interior 16 of the catching shoe 13 is a pocket forms, into which the contact arm 8 can be pivoted.
the Side surface 17 facing away from axis of rotation 10 carries the catching shoe 13 a permanent magnet 18, the north-south axis 19 is aligned at least approximately to the axis of rotation 10.
the north-south axis 19 thus runs approximately parallel to the contact arm 8 in its open position. That way achieved that the generated by the permanent magnet 18 (in Fig. 3 shown) static magnetic field S approximately perpendicular stands on the arc gap 12.
the catching shoe 13 is electrically connected to a blow coil 20, which in turn are electrically connected to the feed line 3 is.
the blow coil 20 is in a coil plane 21 wound, which is arranged parallel to a contact plane 22 is.
the contact level 22 is defined as the level in which the contact arm 8 is pivotable, and the contacts 5 and 9 and the arc gap 12 contains.
Between the blow coil 20 and the contact plane 22 is an insulating wall 23 arranged. This prevents the arc B overlaps the blow coil 20 and this shorts.
the circuit breaker 1 further comprises two rails 24 and 25, which are near each end point of the arc path 12 begin and from there to an arcing chamber 26 extend.
the distance between the runners increases 24, 25 in the course of the extinguishing chamber 26.
the first running rail 24 assigned to the moving contact 9 is attached to the catching shoe 13 in an electrically conductive manner.
the second track 25 is made of a remote from the trigger 11 and beyond the fixed contact 5 extended part of the Contact bracket 4 formed.
the rails 24 and 25 extend about within contact level 22 the arc gap 12, the rails 24, 25 and Extinguishing chamber 26 enclosed area is as an expansion area 27 of the arc B.
the magnetic field direction is within of the catching shoe 13 approximately parallel to the north-south axis 19 of the permanent magnet 18.
the arc B is due to the Lorentz force F1 towards a side wall 28 or 29 of the Catch shoe 13 displaced.
the direction of the Lorentz force is F1 - depending on the direction of current flow within the arc B - either on the side wall 28 or diametrically opposite aligned with the opposite side wall 29.
the arc B thus automatically switches the Blow coil 20, which is now about to the contact plane 22 vertical magnetic field M generated. Under the influence of this Magnetic field M is the arc B with another Lorentz force F2 acts on the arc B in the direction the rails 24,25 acted upon. Under the effect the Lorentz force F2, the arc B jumps from the fixed contact 5 on the adjacent second rail 25 or from the Catch shoe 13 on the associated first running rail 24. Then the arc is along the expansion area 27 supplied to the quenching chamber 26 where the arc B is extinguished becomes.
the leads 2 and 3 After extinguishing the arc B, the leads 2 and 3 electrically isolated. Since there is a reversal of the current flow direction the direction of current flow within the arc B. within the blow coil 20 and thus the direction reverses the magnetic field M, the direction depends on Lorentz force F2 only from the winding direction of the blow coil 20, but not on the direction of current flow.
the sense of winding the blow coil 20 is chosen such that the direction the Lorentz force F2 on the expansion region 27 of the arc B is aligned.
FIG 4 shows an advantageous development of the circuit breaker 1.
the first running rail 24 is not directly connected to the catching shoe 13 connected. Rather, there is between the running rail 24 and the catching shoe 13 an insulating distance 30 is formed.
the Track 24 is connected to the by means of a separate line 31 Supply line 3 connected.
This version has the advantage that after the arc B has skipped onto the track 24 the blow coil 20 is de-energized. Another heating up the blow coil 20 and thus the circuit breaker 1 avoided.
