Definitions
- the invention relates to an attachment module, in particular a communication module with a movable plunger, which is connected via an interface with a switching device having at least one contact piece for switching a contact with contact material.
- the invention also relates to a method for monitoring the life of a switching device with an attachment module, in particular a communication module with a movable plunger, which is connected via an interface with the switching device having at least one contact piece for switching a contact with contact material.
- Electromagnetic switching devices include contactors, disconnectors, power relays and circuit breakers. For such electromagnetic switching devices, in particular for contactors, it is necessary in a variety of applications, the actual switching state of the electromagnetic
- Switching device in contrast, if necessary, to detect a driving state of the electromagnetic switching device to evaluate it elsewhere.
- the switching contact is connected via lines to an evaluation device, so that the switching position of the switching contact and thus the switching state of the electromagnetic switching device can be detected by the evaluation device.
- the detection device is a separate device, which is different from the electromagnetic switching device.
- DE 10 2007 002 176 A1 discloses a detection device for detecting a switching state of an electromagnetic switching device.
- the detection device for detecting the switching state of an electromagnetic switching device has a housing in which a plunger is movably mounted. The plunger is movable between two mechanical end positions, wherein the end positions of the plunger correspond to the switching state of the electromagnetic switching device.
- a sensor device is arranged, from which it can be detected, in which of the end positions the plunger is located, and from which a corresponding electrical signal can be emitted.
- the sensor device is designed such that the position of the plunger can be detected by it, without touching the plunger.
- a disadvantage of the prior art is that the end of life of the switching devices used is not displayed in order to make a timely replacement as part of a maintenance can.
- the invention is therefore based on the object to provide a top module, in particular a communication module for switching devices, which allows life monitoring.
- the invention has for its object to provide a method of the type mentioned above, which allows easy life monitoring of the switching device. These tasks are performed by a communication module with the
- Advantageous education and training which can be used individually or in combination with each other, are the subject of the dependent claims.
- an attachment module in particular a communication module with a movable plunger, which is connected via an interface with a switching device having at least one contact piece for switching a contact with contact material.
- the invention is characterized in that means are provided for measuring the change in position of the plunger with the contact closed, which takes place due to the erosion of the contact material with repeated switching of the contact.
- a particularly advantageous embodiment is when the means for measuring the change in position of the plunger comprise a sensor, and the plunger is provided with a detectable by the sensor element.
- the element is a magnet attached to the plunger.
- a further advantageous embodiment is when the switching device has a processor for evaluating a sensor signal received from the sensor, with which the change in position of the plunger can be determined when the contact is closed due to the contact erosion.
- the processor advantageously serves for logging the values of the position change and for comparing these values with stored empirical values.
- the switching device is provided with a communication interface which serves to transfer an information determined by the processor.
- a further advantageous embodiment is when the communication interface is provided for the connection to a bus. It is advantageous if the bus is an AS-Interface or IO-Link. The further object is achieved by a method having the features of claim 9.
- Interface is connected to the switching device, which has at least one contact piece for switching a contact with contact material, characterized in that via means the change in position of the plunger is measured when the contact is closed, wherein the change in position due to the contact erosion occurs with repeated switching ,
- a particularly advantageous embodiment is when the value determined for the position change is compared with stored values and from this information relating to the life of the switching device is derived.
- FIG. 1 shows a schematic representation of the combination according to the invention of a switching device with an attachment module, in particular a communication module, which has means for monitoring the service life of the switching device.
- FIG. 1 an inventive attachment module 1 is shown with a plunger 2 in a first position on the left and in a second position on the right. Due to the multitude of
- the contact material wears off by burning.
- the life duration of a switching device therefore depends on the remaining amount, that is, the thickness of the contact material and must therefore be monitored.
- the contact wear has a change in position 3 of the plunger 2 with closed contact result. The change in position 3 of the plunger 2 when the contact is closed, as shown by the two positions in the
- the sensor 4 detects in the present embodiment, the magnetic field of a fixedly attached to the plunger 2 magnet 5 and then passes a sensor signal to a processor 6, which is preferably integrated in the switching device 9 and evaluates this sensor signal.
- a processor 6 which is preferably integrated in the switching device 9 and evaluates this sensor signal.
- empirical values are stored, with which the measured value for the position change 3 is compared. From the comparison, a information relating to the life of the switching device 9 is derived.
- the determination of the change in position 3 can take place, inter alia, from a time measurement for the path which the plunger 2 covers when closing and returning. The time measurement begins when the magnet 5 of the plunger 2 is detected during the closing of the sensor 4 and ends after closing the contact when the plunger 2 falls back and in turn while the magnet 5 is detected by the sensor 4.
- the processor 6 is provided with a communication interface 7 in order to be able to communicate this information to a controller 8.
- the sensor 4 can be combined together with the processor 9 in a module, not shown here, which can be placed on the switching device 9.
- the invention which can be placed on a switching device essay module, in particular communication module is characterized by the fact that it is on the measurement of the change in position of the plunger with closed contact, which is caused by the burning of the contact material with repeated switching of the contact conclusions on the possible end of life of Switching device allows so that the switching device can be replaced in good time before its possible failure.
