According to a kind of particularly advantageous execution mode, measured value and the storing value relevant with said change in location are compared, and therefrom derive the information about useful life of said switchgear.
Description of drawings
Fig. 1 is the sketch map of the assembly of the present invention that is made up of a switchgear and an add-on module, particularly communication module, and this add-on module has and is used for switching devices and carries out the member that the life-span monitors.
Embodiment
By embodiment and accompanying drawing other advantages of the present invention and embodiment are described below.
Fig. 1 is the add-on module of the present invention 1 that comprises tappet 2, and the tappet on the left side is in primary importance, and the tappet on the right is in the second place.At the time limit in useful life of switchgear internal memory in a large amount of switching manipulations, so contact material can wear and tear because of scaling loss.Therefore, depend on the surplus (being thickness) of contact material and must being monitored the useful life of switchgear.The change in location 3 of tappet 2 when pitting of contacts can cause the closing of contact.Two diverse locations the during closing of contact in the change in location 3 usefulness accompanying drawings of tappet 2 represent, this change in location shows and have pitting of contacts, and the present invention measures this by transducer 4.In the present embodiment, the magnetic field that 4 pairs of transducers are fixedly mounted on the magnet 5 on the tappet 2 is detected and sensor signal is sent to processor 6, and this processor preferably is integrated in the switchgear 9 and to this sensor signal and analyzes.Processor 6 internal memories have the experience value, supply to compare with measured value about change in location 3.Derive information according to comparative result about the useful life of switchgear 9.Can also through to tappet 2 closed and when resetting the stroke of process carry out time measurement and locate and change 3.When transducer 4 detected the magnet 5 of tappet 2 in the closed procedure process, time measurement began, and after the closing of contact, when tappet 2 resets and transducer 4 when detecting magnet 5 once more, time measurement finishes.
After pitting of contacts took place, the above-mentioned stroke and the time that records all can prolong, and just can derive the change in location 3 of tappet 2 in view of the above.
Add-on module, particularly communication module that the present invention can be inserted on the switchgear are characterised in that; The tappet position changed when contact material can cause the closing of contact because of the contact receives scaling loss that multiple switching operation occurs; And whether this add-on module can be in latter stage in useful life through measuring this change in location switchgear of deriving, thereby before switchgear loses efficacy, in time changes.
