Definitions
- the invention relates to a circuit breaker with current transformers and with an electronic housing Triggers for processing by the current transformers provided signals and with an information store for characteristic properties of the circuit breaker.
- a circuit breaker with these features is through the US-A-5 331 500.
- the one there as an interface card designated information store is so firmly on Structure of the circuit breaker attached that an operative connection with the trigger is only made when the release is inserted into the circuit breaker.
- the signals from the current transformers are triggered by cables transmitted through which the current transformer with the interface card are connected. This gives the trigger one Information about the properties of the circuit breaker.
- the information store is an integral part the circuit breaker is made compared to one likewise known storage of the property values mentioned reliable within the electronic trigger achieves unchangeable features of the circuit breaker, such as type and rated current, as well as the characteristic values of the Current transformer built into the switch, even when Replacement of the electronic trigger unchanged become. But this means that when it occurs an error and subsequent testing of the electronic Trigger such failures can not be detected in the Information stores have occurred. It also needs increased prudence when the current transformer of the circuit breaker are exchanged and therefore also the information store must be adapted or replaced.
- the invention is based, the functional test and fault finding for circuit breakers with one To improve information stores of the type mentioned.
- this object is achieved in that the one with interfaces to the release and to the current transformers trained information store on the outside of the Trigger is releasably attached. This ensures that the trigger only together with the information store can be removed from the circuit breaker. Will therefore be a functional test a release removed from the circuit breaker carried out, it is inevitable in the functional test the information store is also included. Becomes a malfunction determined, this ensures that that the troubleshooting is equally focused on the Trigger itself extends to the information store. If it turns out to be necessary, only that To exchange triggers, the information store of the affected trigger and on the new trigger be added. The property parameters are thus accepted.
- the information store on one Operating front of the trigger rear wall is arranged is and that the interface to the trigger and the Interface to the current transformers on opposite Sides of a circuit board of the information store arranged This enables the Information store on the trigger with only a small depth.
- the invention is based on the in the figure illustrated embodiment explained in more detail.
- the figure shows schematically in a side view or in Cut a low voltage circuit breaker with one electronic trigger accessible from the front and one on the back of this arranged information store.
- a circuit breaker 1 is shown schematically in the figure as Outline shown.
- An electronic trigger 2 is in the Circuit breaker 1 housed so that its front panel 3 on the front 4 of the circuit breaker 1 is accessible.
- a housing 5 of the trigger 2 has fastening legs 6 on the abutments 7 of the circuit breaker 1 and with them represented by schematically Connection means 10 are connected.
- 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 to control the electronic release 2 serves.
- An information memory 14 is located on the front of the control panel 3 of the electronic trigger 2 opposite rear wall 15 arranged.
- the information store 14 has its own Housing 16 with a fastening member 17 which is used for support on the lower mounting leg 6 of the housing 5 of the Trigger 2 is provided and with this by a likewise to connect schematically shown fastener 20 is.
- Interfaces 18 and 19 allow a simple one electrical connection of the information store with the Trigger 2 and the current transformers 13.
- a circuit board 21 with components that are used for transmission signals provided by the current transformers 13 and for the Current transformer and the circuit breaker more characteristic Property characteristics serve.
- the circuit board 21 is on opposite sides with components 22 and 23 of Provide plug connections. Other components of this Plug connections are a socket 24 and a Multiple connector 25.
- the component 22 acts with the on Rear wall 15 of the housing 5 of the electronic release 2 arranged socket 24 together while the component 23 for inserting the multiple plug 25 for connection with the current transformers 13 is freely accessible.
- Components 22 and 24 together form the interface 18 and the Components 23 and 25 form the interface 19.
- the electronic trigger 2 can Removal of the fasteners 10 from the circuit breaker 1 taken together with the information store 14 can be. Should another trigger in the Circuit breaker 1 are installed, so the Information store 14 by removing the fastener 20 and separation of component 22 from the socket 24 solved and can on the new trigger in the same way be attached. This will also be the new trigger for the current transformers 13 and the type of the circuit breaker 1 specific property values communicated.
- the test can first done for the unit of trigger and information store and if necessary separately for the trigger 2 and the information store 14 are continued. Therefore, it is also possible a faulty information store easier to recognize and replace if necessary.
