Definitions

  • the invention relates to a medium-voltage switchgear with separation and three-position switches, according to the preamble of claim 1.
  • Disconnectors and three-position switches are designed for medium-voltage switchgear for two typical current carrying capacities.
  • a common standard compliant value according to IEC is 1,250 amperes and another value is 2,500 amperes. Accordingly, different components of said switches are required for the different current carrying capacities. This different interpretation has manufacturing disadvantages.
  • Knife separators are known with specific design of the knife, which should increase the mechanical reliability when switching, but not the current carrying capacity.
  • the invention is therefore the object of further developing a medium-voltage switchgear of the generic type to the effect that different conversions of the current carrying capacity are easier to implement.
  • the core of the invention is that by multiple arrangement of the same contact systems (1) per phase (L1, L2, L3) in parallel arrangement on a common switching axis (2) the achievable current carrying capacity is increased with respect to a base current carrying capacity by that in the switching axis a mechanical rotary or Drill Kliselement is integrated with which the switching axis itself is mechanically torsionally rigid.
  • a mechanical rotary or Drill Kliselement is integrated with which the switching axis itself is mechanically torsionally rigid.
  • the base current carrying capacity is 1250 amps, and the contacts of the disconnecting and / or three-position switches are designed thereon.
  • the current carrying capacity at 2,500 amperes is effected by a parallel arrangement of two contact arrangements placed on a switching axis, whose base current carrying capacity is designed in each case at 1,250 amperes.
  • the switching axis consists of plastic.
  • the switching axis may also consist of a ceramic material.
  • Another advantageous design alternative is characterized in that the switching axis of metal, and the shift lever of the separating or three-position switch made of plastic.
  • FIG. 2 shows an arrangement of 3 contact components or arrangements 1 on a switching axis, and this for every three three-phase L1, L2 and L3. In each case one contact arrangement per three-phase phase is provided.
  • FIG. 1 shows that in each case 2 parallel contact arrangements 1 are arranged on the axis or switching axis 2 for each phase.
  • this axis moves the levers, which in turn move the contacts themselves.
  • each contact arrangement ie per phase equipped with a current carrying capacity of 1,250 amperes. Due to the double arrangement in FIG. 1 Accordingly, a total current carrying capacity of 2,500 amps is achieved.
  • 1,250 ampere switchgear with the same prefabricated contact arrangements such as 2,500 amp switchgear can be created. This by merely doubling the contact arrangements per phase, and this on one and the same switching axis.
