Definitions
- the invention relates to a circuit breaker with current transformers and with an electronic release having a housing for processing signals provided by the current transformers, and with an information store for property characteristics of the circuit breaker.
- a circuit breaker with these features is known from US-A-5 331 500.
- the information store referred to there as the interface card is so firmly attached to the structure of the circuit breaker that an operative connection with the release is only established when the release is inserted into the circuit breaker.
- the signals of the current transformers are transmitted to the trigger by lines through which the current transformers are connected to the interface card. This gives the trip unit information about the properties of the circuit breaker.
- the information memory is made an integral part of the circuit breaker means that, in comparison to a known storage of the characteristic properties mentioned within the electronic release, unchangeable features of the circuit breaker, such as type and rated current, and the characteristic values of the likewise, current transformers permanently installed in the switch can be taken into account unchanged even when the electronic release is replaced. However, this means that when an error occurs and the electronic trigger is subsequently checked, such faults are not recognized that have occurred in the information memory. Furthermore, increased caution is required if the current transformers of the circuit breaker Be exchanged and therefore the information store must be adapted or exchanged.
- the invention has for its object to improve the function test and fault finding in circuit breakers with an information store of the type mentioned.
- this object is achieved in that the information store formed with interfaces to the trigger and to the current transformers on the outside of the
- Trigger is releasably attached. This ensures that the trigger can only be removed from the circuit breaker together with the information store. Therefore, if a function test of a trip device removed from the circuit breaker is carried out, the information store is also necessarily included in the function test. If a malfunction is found, it is ensured in this way that the malfunction search extends equally to the trigger itself and to the information store. If it proves necessary to replace only the trigger, the information store can be separated from the trigger concerned and attached to the new trigger. The property parameters are thus adopted.
- the information memory be arranged on the rear wall facing away from an operating front of the release and that the interface to the release and the interface to the current transformers be arranged on opposite sides of a printed circuit board of the information store. This enables the information store to be attached appropriately Triggers with only a small depth.
- the information store has its own housing with a fastening member serving for connection to the trigger.
- the figure shows schematically in a side view or in section a low-voltage circuit breaker with an electronic release accessible from the front and an information memory arranged on the rear thereof.
- a circuit breaker 1 is shown schematically in the figure as an outline.
- An electronic release 2 is accommodated in the circuit breaker 1 so that its operating front 3 is accessible on the front side 4 of the circuit breaker 1.
- a housing 5 of the trigger 2 has fastening legs 6 which abut abutments 7 of the circuit breaker 1 and are connected to them by means of schematically illustrated connecting means 10.
- the circuit breaker 1 contains schematically indicated current paths 11, each with a switching contact system 12. Each of the current paths is provided with a current transformer 13, the output signal of which is used to control the electronic release 2.
- An information memory 14 is arranged on the rear wall 15 opposite the operating front 3 of the electronic trigger 2.
- the information memory 14 has its own housing 16 with a fastening element 17, which is provided for resting on the lower fastening leg 6 of the housing 5 of the trigger 2 and can be connected to the latter by a fastening means 20, which is also shown schematically.
- Interfaces 18 and 19 allow a simple one electrical connection of the information store to the release 2 and the current transformers 13.
- a printed circuit board 21 with components which serve for the transmission of signals provided by the current transformers 13 and for characteristic characteristic values which characterize the current transformers and the circuit breaker.
- the circuit board 21 is provided on opposite sides with components 22 and 23 of plug connections. Further components of these plug connections are a plug base 24 and a multiple plug 25.
- the component 22 interacts with the plug base 24 arranged on the rear wall 15 of the housing 5 of the electronic release 2, while the component 23 for plugging in the multiple plug 25 for connection to the current transformers 13 is freely accessible.
- the components 22 and 24 together form the interface 18 and the components 23 and 25 form the interface 19.
- the electronic release 2 can be removed together with the information memory 14 after the fastening means 10 have been removed from the circuit breaker 1. If another release is now to be installed in the circuit breaker 1, the information memory 14 is previously released by removing the fastening means 20 and separating the component 22 from the plug base 24 and can be attached to the new release in the same way. The characteristic values specific to the current transformers 13 and the type of the circuit breaker 1 are thus also communicated to the new trigger.
- the test can first be carried out for the unit of the release and the information store and, if necessary, can be continued separately for the release 2 and the information store 14. Therefore, it is it is also possible to identify a faulty information store more easily and replace it if necessary.
