Definitions

  • the invention relates to an electromagnetic switching device with main and leading contacts, which can be interconnected with damping resistors under capacitive load.
  • the invention has for its object to construct a switching device of the type mentioned above so that when using the damping series resistors, a compact unit is obtained using electrical switching devices constructed essentially in series. This is achieved in a simple manner in that the main and leading contacts in the switchgear lie one above the other on two levels and there are electrical bridges on the leads of two different contacts across both levels and their derivatives via La 2 Syr / 28.01.1981 Resistors are bridged.
  • the compact unit and thus also the security against contact, without having to carry out a cover, is further increased if the resistors wound from insulated wire are at least partially between the dividing ribs of two phase walls. This also results in increased break resistance.
  • the J 2 t value is higher with the same resistance value and the same dimensions for the resistance.
  • the switching device shown in Fig. 1 has a housing 1 in which the main contacts 2 and the leading contacts 3 are arranged one above the other in two levels 4 and 5.
  • the switching device has three pole tracks with main contacts 2 and leading contacts 3.
  • the last track 6 is occupied with a normal break contact on floor 4 and a make contact on floor 5.
  • the individual contacts consist of the fixed contact parts 7 and those in a contact bridge holder 8 the contact bridges 9 held in the known manner.
  • the contact bridge holder 8 is actuated by a magnetic drive, not shown.
  • the fixed contact parts 7 are equipped with terminals 10, which are covered by plastic covers 11 against contact.
  • Electrical bridges 12 are present on the supply side of the main contacts 2 and the leading contacts 3, which are inserted into the terminals, for example in the form of wire stripped in the area of the terminals.
  • the supply lines 13 of the network are also clamped in one of the terminals either on the main contact 2 or on the leading contact 3.
  • resistors 14 are clamped with their ends into the terminals of a main and a leading contact.
  • the resistors 14 are designed as wire coils and are insulated and are located between two dividing ribs 15 of the housing 1 and are protected against external influences. Since the switching device is tapered towards the top, practically no additional space is required to accommodate the resistors.
  • FIG. 2 The insertion of resistors, bridges and contacts into the overall circuit can be seen in FIG. 2.
  • one feed line 13 is connected to the bridge 12 and thus to a main contact 2 and a leading contact 3.
  • the other sides of the main contact 2 or the leading contact 3 are bridged via the resistor and electrically connected to the lead 16 to the capacitors 17 connected in a triangle.
  • the circuit constructed in this way first connects the capacitors 17 to the network via the series resistors 14, specifically via the leading contact 3, and after the contact 2 is closed, the series resistors 14 and the leading contacts 13 are bridged.
  • the capacitors 17 are switched off, the process is carried out in the reverse order, so that switch-off damping is also present here; because the leading contacts 3 only open after the main contacts 2 have already opened.
  • the circuit shown in FIG. 3 uses only two resistors 14.
  • two main contacts 2 which are assigned to the resistors 14, are connected in parallel.
  • the third phase is connected to the power supply line 13 via a leading contact 3 connected in parallel and a normal normally open contact.
  • the contactor used here has five pole tracks as a two-day contactor.
  • the fifth pole track with the make contact and the break contact is used for monitoring and control purposes.
  • the parallel connection of the current paths serves to increase the current carrying capacity.
