Definitions

  • the invention relates to an electrical circuit breaker with isolating contacts for main circuits, a connection device for auxiliary circuits and with a stationary contact device which interacts with the connection device, the circuit breaker being able to assume an operating position and an isolating position and an intermediate test position with respect to the isolating contacts, and the connection device for auxiliary circuits in the operating position and in the test position is connected to the fixed contact device and furthermore, on a plug-in frame receiving the circuit breaker, signaling switches for detecting and signaling the aforementioned positions of the circuit breaker in the plug-in frame and an interface module are arranged, which are transmitted from the contact device and from the signaling switches
  • Plug-in circuit breakers of this type are mostly used in conjunction with plug-in frames which are designed as carriers for fixed isolating contacts and the aforementioned fixed contact device. Examples of such arrangements can be found in US 4 139 748, US 4 743 715 and US 5 594 221. A large number of signals are transmitted via the contact device, both from the movable circuit breaker to the slide-in frame and vice versa. It is particularly important to signal the position of the circuit breaker in the slide-in frame (operating position, test position, Disconnect position) in order to be able to monitor the switching status and the operational readiness of the circuit breakers in a switchgear system using 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 circuit breaker located in the slide-in frame. This also records the condition that there is no circuit breaker in the rack.
  • fieldbus systems which in the simplest case are independent of the number of switching devices with four wires (two Signal wires, two wires for the power supply). Examples for the use of fieldbus systems are described in DE 197 06 961 AI or EP 0 736 946 B1. Messages and commands between the protection module (electronic overcurrent release) and a control room or control center and the position reports of the circuit breaker in the slide-in frame must therefore be fed into such a fieldbus system.
  • interface module interface module; gateway
  • the interface module must be connected to the protection module and the signaling switch module by direct (1: 1) wiring , as described in EP 0 923 175 AI.
  • the signaling switches are located on the (facing the circuit breaker) Inside of a side wall of the slide-in frame, while the
  • Interface module is attached to the opposite outside. Common fasteners for the
  • the signal switch and the interface module penetrate the side wall.
  • the invention has for its object to reduce the effort for wiring and fastening the components described and to enable compact overall dimensions.
  • this object is achieved in that the contact device, the interface module and the signaling switch are combined to form one structural unit. This shortens the wiring so that it does not
  • Interface module the contact device and the signaling switch can be.
  • the invention is explained in more detail below on the basis of the exemplary embodiment illustrated in the figure.
  • the figure shows a schematic representation of the interacting assemblies of the circuit breaker and the slide-in frame in connection with a fieldbus system.
  • the figure shows, as interacting units, a slide-in 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 of more detailed explanations is disregarded. It should only be pointed out that a slide-in frame is shown in DE 201 05 889 Ul and that low-voltage circuit breakers of a suitable design are also familiar to the person skilled in the art.
  • 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.
  • the actuating magnets 4 and 5 ensure that latching parts are released in the Switching mechanism of the circuit breaker to enable the desired switching operations.
  • Said units, electronic overcurrent release 3, actuating magnets 4 and 5 are connected to a connection device 6, which is attached in a known manner to the circuit breaker 2 in such a way that it can engage with a contact device 7 located on the insert frame 1.
  • the assembly 10 also contains a signaling switch assembly 13 for detecting the presence of a circuit breaker 2 in the slide-in frame 1 and the respective position (disconnected, test or operating position).
  • a dashed arrow indicates that the
  • Interface module 14 also other signals, for. B. from other identical or similar units, can receive and process, which are transmitted via a communication system 15. Furthermore, through connections between the
  • Contact device 7 and the interface module 14 indicated that the overcurrent release 3 and the actuating magnets 4 and 5 can be influenced both by means of the fieldbus system 12 and by means of the communication system 15. In this way, for example, the circuit breaker can be switched on or off by remote control or response values of the overcurrent release 3 can be changed.
  • the previously reported position report of the circuit breaker 2 (not available or present and in the position disconnect / test / operation) ensures that only executable commands or commands are only transmitted when the operating state of the circuit breaker is processing the commands allows.

Abstract

Un disjoncteur électrique (2) présente des contacts de sectionnement destinés à des circuits électriques principaux et un dispositif de raccordement (6) destiné à des circuits électriques auxiliaires qui coopèrent avec un dispositif de contact (7) stationnaire. Un cadre à glissière (1) destiné à loger le disjoncteur (2) abrite des interrupteurs de signalisation (13) destinés à la détection et à la signalisation de la position du disjoncteur (2) dans le cadre à glissière (1). Les interrupteurs de signalisation (13) sont, en termes de construction, directement associés à un ensemble interface (14) qui traite les signaux du dispositif de contact (7) transmis par les interrupteurs de signalisation (13) aux fins de retransmission à un système de bus de terrain (12).
