Definitions

  • the invention relates to a circuit arrangement for simultaneously placing several electrical consumers on a supply network by indirect actuation of a switch.
  • the strip can have a switch which acts jointly on all sockets, when it is actuated all connected consumers are switched on or off together.
  • a circuit arrangement of the type mentioned is known from DE-OS 23 47 508.
  • An overvoltage is applied to the supply network using a capacitor.
  • the capacitor is short-circuited by actuating a switch. Its discharge current is controlled by a relay that switches on the consumers.
  • a relay on the supply network is triggered by pressing a button and switches the ver need also to the network.
  • the invention was therefore based on the object to admit a circuit arrangement with which the consumers can be connected to the next generally available access to the supply network, in which, in addition to efnem switches on the consumer, no further manually operated switches are required and in which the Central connection point for the large number of consumers can be arranged at any point outside the work surfaces to be assigned to the consumers.
  • the circuit arrangement should include the
  • This task is solved according to the invention in a circuit arrangement of the type mentioned at the outset in that a first circuit is provided in which a first electrical consumer which can be determined as desired can be inserted; whose mains switch acts as a switch for the commissioning of all consumers, a second supply circuit, which can be connected via an electrically controllable switch, is provided, which contains a number of mains connection sockets corresponding to the desired number of further consumers, and that the first supply circuit has a switch controlling current sensor is assigned.
  • An essential part of the invention is therefore to derive a control signal for switching on the other consumers solely from the commissioning of one of the consumers.
  • the advantage of the new circuit arrangement lies in the fact that one of a number of consumers to be fed at the same time can be used to determine which one belongs to the first circuit, and by means of its power switch not only turn it on but also all other consumers to the feeding network. can switch off from this, the power switch of the latter consumer can always remain in the on position.
  • the circuit arrangement can be summarized in a connector strip which is connected in a conventional manner to the supply network. After being connected to the consumers, it can be stored anywhere outside of the work area required to serve the consumers.
  • the current sensor can be followed by a delay element and an inrush current limiter arranged downstream of the electrically controllable switch in the second supply circuit.
  • An EMC filter can also be connected upstream of at least one of the supply circuits.
  • Supply circuit 1 is provided with a socket 3 for a first consumer having a power switch.
  • Supply circuit 2 has a plurality of sockets 4 - 7, which are connected in parallel to each other. This is preceded by an electrically actuable, two-pole switch 8, which is triggered by a current sensor 9 assigned to the supply circuit 1 and excited by it.
  • the user selects one from the consumers to be connected and fed, by means of whose power switch he also wants to switch the remaining consumers, and closes this via the socket 3 (master) on.
  • the other consumers are connected to sockets 4 - 7 (slaves) and their mains switches - if available - are set to the "ON" position.
  • an inrush current limiter 10 can be provided behind the switch 8 in the supply circuit which is switched by a current delay element 11 from the current sensor 9.
  • the supply circuit 2 behind the switch 8 can be divided into parallel branches with a number of sockets 4 - 7 or 4 '- 7' etc., each of which has its own switch-on current limiter 10 or 10 ', etc., and a time delay element 11 or 11', etc. assigned.
  • the time delays are selected differently so that the switch-on current limiters come into effect one after the other.
  • At least one EMC filter 12 which largely prevents the transmission of interference from the network to the new circuit or from the new circuit to the supply network.
  • it can be assigned to one of the two supply circuits or, as shown, to both supply circuits together.
