Definitions

  • the invention relates to an electromagnetically operated switch whose switching elements, with the exception of the exciting coil, are enclosed in a container, for instance a glass container, which is evacuated or filled with an indifferent gas.
  • a container for instance a glass container, which is evacuated or filled with an indifferent gas.
  • the above mentioned exciting coil as a rule, surrounds the container, hereinafter called vacuum container, which includes containers filled with an indifferent gas.
  • the pole-shoe as well as the armature is arranged inside the vacuum container.
  • the armature and the pole-shoe with the greatest possible face are arranged closely adjacent the inner wall of the container, and there is a fully or partly closed ferromagnetic casing for the exciting coil, constructed in such a way that the greatest possible face lies adjacent the outer wall of the container opposite the armature and pole-shoe.
  • Fig. 1 is a longitudinal sectional view of the switch.
  • Fig. 2 is a similar view illustrating a modification of the magnetic circuit.
  • Fig. 3 is a cross sectional view of the apparatus shown in Fig. 2.
  • the vacuum switch itself consists of a fixed contact I and a movable contact 2.
  • the fixed contact I is fitted into an insulating body 3 adjoining another insulating body 4, the latter being the guide for the movable contact 2.
  • Fastened to the two insulating bodies 3 and 4 is the pole-shoe 5, or the not-movable ferromagnetic 1 portion of the vacuum switch.
  • armature 6 Opposite this pole-shoe 5 there is an armature 6 as the movable portion of the switch.
  • This armature can slide along the periphery of the insulating body 3.
  • the armature 6 is also guided by two guiding rods 1, by which the insulating bodies 3 and 4 are at the same time held together.
  • the armature 6 is urged away from the pole-shoe 5 by a spring 8, while a plate 9, pressed into the armature, engages a pin H] in the movable contact 2, whereby the contacts are kept open against the pressure of the spring H.
  • a plate 12, secured to the end of the guiding rods 1, serves to limit the movement of the armature 6.
  • the plate 12 is provided with a few elastic attachments l3, serving to support the whole switching system against the wall of the vacuum container 14.
  • the movable contact is electrically connected with the guiding rods 1 by means of an elastic current bridge l5.
  • Two current conductors 16 are sealed at I! in the vacuum container and are connected at l8 and H) with the movable contact through the guiding rods 1 on the one hand, and on the other hand with the fixed contact.
  • the vacuum container is shown as a tubular body.
  • the pole-shoe and armature are also formed tubular so that the faces of these two parts on a very long distance lie closely adjacent the glass wall.
  • the vacuum container 14 is located within an electromagnetic coil 20.
  • This electromagnetic coil is surrounded by a pot-shaped force-1ines-conducting-vessel 2
  • the ends 22 must not be so near to each other that between them a stray flux is caused, evading the armature and pole-shoe, which would weaken the action.
  • Two or more coils may be used which have two or more separate conductors of lines of force which generate in the pole shoe and armature two or more independent fluxes or lines of force and thereby prevent the vibration of the armature.
  • a constructional example of this type is shown in Figures 2 and 3.
  • 26 is the vacuum container in which there are two separate pole shoes 24, 35 and two separate armatures 25 and 36 belonging thereto.
  • 21 and 38 indicate two coils which have a ferromagnetic core 28 or 3! and conducting pieces 29 and 32. These conducting pieces 29 and 32 are separate as shown in Fig. 3 and closely adjoin the major portion of the circumference of the glass container 26.
