Definitions

  • the invention relates to an electrical circuit breaker with isolating contacts for main circuits, a connection device for auxiliary circuits and with a cooperating with the terminal stationary mounted contact device, the circuit breaker with respect to the isolating contacts can occupy an operating position and a disconnected position and an intermediate test position and the connecting device for auxiliary circuits in the operating position and in the test position is connected to the stationary contact device and further arranged on a circuit breaker receiving frame signaling switch for detecting and signaling the said positions of the circuit breaker in the drawer frame and an interface module, which from the contact device and the signal switches transmitted signals to Transfer to a fieldbus system processed
  • Plug-in circuit breakers of this type are mostly used in conjunction with slide-in frames, which are designed as carriers of fixed isolating contacts and the mentioned stationary contact device. Examples of such arrangements are the US 4,139,748 . US 4,743,715 and U.S. 5,594,221 refer to.
  • Via the contact device a plurality of signals is transmitted, both from the movable circuit breaker to the drawer frame and vice versa. It is essential in particular a signaling of the position of the circuit breaker in the drawer frame (operating position, test position, Isolated position) to monitor the switching state and the operational readiness of the circuit breaker of a switchgear by means of a central control room.
  • This signaling or auxiliary switch assembly is located on a side wall of a slide-in frame and is actuated by a power switch located in the withdrawable frame. This also detects the condition that there is no circuit breaker in the withdrawable rack.
  • the invention has for its object to reduce the cost of wiring and attachment of the components described while allowing compact overall dimensions.
  • this object is achieved in that the contact device, the interface module and the signaling switch are combined to form a structural unit.
  • a conventional wiring can be completely eliminated, since, for example, a single circuit board can also be the carrier of the interface assembly, the contact device and the signaling switch.
  • FIG. 1 shows a schematic representation of the cooperating modules of the circuit breaker and the slide-in frame in conjunction with a fieldbus system.
  • the figure shows as cooperating units a drawer frame 1 with a low-voltage circuit breaker 2 inserted therein.
  • the structure of these units in detail is immaterial in the present context, which is why details will be omitted.
  • a slide-in frame in DE 201 05 889 U1 is shown and that low-voltage circuit breakers of a suitable design are also familiar to the expert.
  • an electronic overcurrent release 3 belonging to the circuit breaker 2 an actuating magnet 4 for switching off and another actuating magnet 5 serving for switching on the circuit breaker 2 are indicated.
  • the actuation magnets 4 and 5 ensure release of latching parts in the switching mechanism of the circuit breaker to allow the desired switching operations.
  • Said units, electronic overcurrent release 3, actuating magnets 4 and 5 are connected to a connection device 6 which is mounted in a known manner on the circuit breaker 2 such that it can engage with a contact frame 7 located on the contact device 7 in engagement.
  • the assembly 10 further includes a signaling switch assembly 13 for detecting the presence of a circuit breaker 2 in the drawer frame 1 and the respective position (separation, test or operating position).
  • the overcurrent release 3 and the actuating magnets 4 and 5 can be influenced both by means of the field bus system 12 and by means of the communication system 15.
  • the circuit breaker can be switched on or off by remote control or it can response values of the overcurrent release 3 can be changed.
  • it is ensured by the respective previously transmitted position message of the circuit breaker 2 (not present or present and in position separation / test / operation) that only executable instructions or only commands are transmitted when the operating state of the circuit breaker allows processing of the commands.
