Abstract

The invention relates to a gas insulated medium voltage switchgear with a 3 position disconnector device for 3 electric phases on one common rotatable driveshaft.
In order to realize a common construction, the three position disconnector device for three phases is arranged in one common functional unit, which has a base plate and a frame, and which can be mounted in a switchgear housing, in that way, that the baseplate and/or the frame is after the mounting a part of a gastight housing of the switchgear.

Description

  • The invention relates to a gas insulated medium voltage switchgear with a 3 position disconnector device for 3 electric phases on one common rotatable driveshaft.
  • In well known gastight medium voltage switchgears three-position disconnector devices are assembled in the housing, in that way, that different components of the device are fixed mechanically on different parts of the housing of the switchgear.
  • This guides to the following problems.
    • The assembly is complicated and time consuming, as the accessibility is restricted by the available openings in the housing of the switchgear.
    • The adjustment of the three-position disconnector devices has to be done in the final assembly line.
    • The functional test of the three-position disconnector devices has to be done in the final assembly line.
    • The external sourcing of the complete assembled disconnector device from subsuppliers is not possible.
  • So it is an object of the invention, to overcome all these disadvantages with a compact construction, which is easy to adjust before mounting.
  • The basical features of the invention are, that the three position disconnector device for three phases is arranged in one common functional unit, which has a base plate and a frame, and which can be mounted in a switchgear housing, in that way, that the baseplate and/or the frame is after the mounting a part of a gastight housing of the switchgear.
  • This reduces the assembling or mounting time because of a better accessability. Furthermore, the preassembled unit is easier to adjust, before it will be mounted inot the switchgear housing.
  • A further advantageous embodiment is, that the fixed contacts of the disconnector device are mounted on the base plate with integral bushings, which are furthermore connectable to the solid insulated busbars at the outside part of the housing of the switchgear.
  • Furthermore the frame is mounted on the base plate, and that the frame carries the fixation of the driveshaft.
  • Optionally, the earth contacts are fixed to the frame
  • A further very advantageous embodiment is, that the common functional unit closes the housing of the switchgear after mounting in a gastight way.
  • To realize this gastight closing of the housing, one possible solution is, to realiz it by welding after it is mounted in the housing, or to screw it by the use of a sealing element around the opening of the housing, in which the functional unit is placed.
  • An embodiment of the invention is shown in the drawing.
  • The figure shows a perspective view of a three phase disconnector device in one common unit. The movable contacts are arranged operated by a turnable driveshaft. The driveshaft is positioned and fixed on both side in a frame, which is mounted on a base plate. In the base plate are fixed not movable contacts which are mounted on integral bushings. These bushings are connected to external bushbars.
  • So the common unit can be assembled and adjusted before it has to be mounted into the housing of the switchgear.
  • Furthermore the electric sourcing with external bushbars is easy and effective.
