Definitions
- the present invention relates to a method for operating a switching device according to the preamble of claim 1 such as ⁇ a corresponding device according to the preamble of claim 8.
- switching devices in particular low-voltage switchgear, the current paths between an electrical supply device and consumers and thus their operating currents can be switched.
- the connected consumers can be reliably switched on and off.
- a low-voltage electrical switching device such as ⁇ a contactor, a circuit breaker or a compact starter, has one or more so-called main contacts for switching the current paths, which can be controlled by one or more control magnets or electromagnetic drives.
- the main contacts consist of a movable contact bridge and fixed Kunststoffstü ⁇ bridges, to which the consumer and the supply device are connected.
- a corresponding on or off signal is given to the electromagnetic drive, whereupon they act with their armature on the movable contact bridges that the contact bridges perform a relative movement with respect to the fixed contact pieces and close either to be switched current paths or open.
- contact surfaces pre ⁇ are made of materials, such as silver alloys, which are used at these locations. probably on the contact bridge and the contacts are placed on ⁇ and have a certain thickness.
- the electromagnetic drive is designed as a lifting magnet.
- the solenoid has a plunger coil as an excitation coil and an anchor.
- For magnetic flux guidance of the electromagnetic drive is surrounded by a Ei ⁇ senjoch.
- the exciting coil is now applied to turn on the switching device with a current, the armature is attracted hineinge ⁇ into the cylindrical opening of the excitation coil.
- a mechanically connected to the armature contact slide is actuated, which in turn moves the contact bridge to close the main contacts.
- a switching device of the above kind has the READY ⁇ development of the coil current for the exciter coil is a Stromversor ⁇ supply, which generates from a network-side AC input voltage a low-voltage DC voltage ranging from 12 V to 24 V. Typical network side input voltages are 230 V at 50 Hz or 110 V at 60 Hz. Newer clocked Stromversor ⁇ conditions have a wide input voltage range of about 100 V to 230 V on.
- the power supply can also supply a control and monitoring electronics of the switching device with power.
- the ON position can be queried by means of one or more switching contacts, via which then the reduction of the coil current can be effected by the power supply.
- the disadvantage of this solution is that the contacts of the switches can become dirty. In this case, as in the case initially described in turn the increased Spu ⁇ would lenstrom from the power supply with the above mentioned possible adverse effects can be provided.
- Object of the present invention is to identify these particular potential sources of error and yaw accordingly to rea ⁇ .
- the present invention allows ei ⁇ ne reliable control of the coil current and a reliable casual feedback on the fact that the electromechanical drive on ⁇ has carried out an actuation movement.
- a magnetic flux change in the electromagnetic drive is detected between a first position when the main contact is switched off and a second position when the main contact is switched on and a coil current of the electromagnetic drive is limited to a predetermined minimum current value in the second position if the magnetic flux change is predetermined Value has exceeded.
- the electromagnetic actuator 1 is supported by at least one permanent magnet 8, so that in the ON and in the OFF position-1 of the electromagnetic drive additional holding ⁇ force on the armature 10 is produced.
- the permanent magnets 8 are attached to the outside of the inner yoke 5 of the electromagnetic drive 1.
- the magnetic poles of the two permanent magnets 8 are each designated by the processesszei ⁇ chen N and S.
- the permanent magnets 8 are arranged ⁇ preferential manner along the circumference of the inner yoke. 5
- a magnetic ring or ring which is polarized such that a north pole N or south pole S forms on its inside and a south pole S or north pole N forms on the outside thereof.
- the magnetic flux change can also be detected or measured alternatively or additionally in a stray field MF2 of one of the permanent magnets 8.
- a magnetic sensor or a Hall sensor 3 is attached to the outside of the inner yoke 4 and in the region of the upper permanent magnet 8.
- the magnetic flux extends - as shown in the lower part of Figure 2 - from the north pole N on the outer yoke 5, further on the stop plate 12 and the zy ⁇ - cylindrical pin 11 of the armature 10 in the inner yoke 5 in the initial region EO of the cylindrical opening OF to the south pole S of the permanent magnet 8.
