Definitions
- the invention relates to a switch disconnector for medium voltage according to the preamble of claim 1.
- the load disconnect has a fixed contact piece arrangement and a movable contact piece arrangement, which is fastened to a contact spindle or contact rod as a contact carrier, which is coupled to a pivot lever drive, which is actuated by a drive shaft.
- the contact point comprises a main contact point and an arc tear-off point, the main contact point having a pot contact piece with contact fingers.
- the object of the invention is to optimize a load-break switch of the type mentioned.
- FIG. 2 shows the contact point according to FIG. 1 shortly before the switch-off position
- Fig. 3 is a perspective view of the main contact point at further switching off and
- Fig. 4 is a perspective view of a contact pin.
- the contact point of a load-break switch drawn there is located in a pot-shaped housing 10 made of insulating plastic, as has become known from DE 10 2005 009 207.1.
- the container 10 is closed at its free end with a bottom portion 11 in which a cylindrical contact portion or sleeve 12 is fixed, the or has a bore 13 through which a connecting line according to arrow P can be connected.
- a fixed main contact piece 14 connects, which is tulip-shaped with a bottom plate 15 and adjoining contact fingers 16, which have a confinement 17 inwardly at their free ends.
- a contact pin 18 is fixed, which is shown in more detail in FIG. 4.
- a contact carrier 19 in the form of a contact rod, at the inner end of a sealing plate is fixed, which carries on its outer periphery a seal 21 which bears against the inner surface of the container 10 and serves for sealing there.
- a cylinder 22 On the plate 20, a cylinder 22 is fixed, which carries on its inner surface a nozzle-shaped contact piece 23, wherein the nozzle shape forms the inner contour 24.
- the cylinder 22 has at its end opposite the contact piece 23 a radially inwardly projecting bar 25, which comprises the contact rod 19 and is firmly connected therewith.
- the interior 26 of the cylinder 22 is provided in the region of the strip 25 with passage openings 27 which connect the interior space 26 with the space 28 below the plate 20 in the axial direction.
- a blowing cylinder 29 is attached from insulating plastic.
- Fig. 4 shows the contact pin 18.
- This contact pin 18 is approximately cylindrically shaped and has a pin portion 30 which is non-positively inserted into the bore 13.
- the section 30 is followed by a hexagonal plate portion 31, which abuts against the inner surface 32 of the bottom 15 of the main contact piece 14 and the main contact piece 14 with the contact cylinder 12 firmly connects.
- the contact pin 18 has a contact finger portion 33 which has at its free end radially an enlarged portion 34 which gives the contact pin 32 has a microphone-like structure.
- the contact pin 32 has an axially extending longitudinal slot 33, whereby two contact pin fingers 35 and 36 are formed.
- the outer diameter of the portion 34 is greater than the inner diameter of the contact piece 23, so that when an elimination takes place, so if the contact piece carrier is pulled in the direction of arrow Pi, the inner surface of the contact piece 23 slides on the outer surface of the portion 34 and thus the two contact pin fingers Press 35 and 36 towards each other.
- the contact piece 23 is made of arc-resistant material, as well as the section 34th
- the blowing cylinder 29 has an opening 40 whose inner diameter corresponds approximately to the outer diameter of the section 34. In the position shown in FIG. 2, the blowing cylinder 29 slides with its opening on the portion 34. As soon as the contact piece 23 separates from the portion 34 of the contact pin 32, there forms an arc 43 (see Fig. 3), which is blown by the blowing cylinder 29 made of insulating material with the gas in space 41 of this.
- the insulating plastic of the blowing cylinder 29 is made of gas-releasing material, whereby the arc between the portion 34 and the contact piece 23 is optimally blown.
- Fig. 3 shows the contact arrangement shortly after the separation of the contact piece 23 from the section 34, in which case the arc 43 is pulled, which is extinguished by extinguishing gas flowing out of the space 41 in the direction of arrow P 2 .
- a cup 50 is electrically connected fixedly surrounding the container 10 and carries in the region of the contact point between the contact piece and the contact cylinder 22 located field control ring 51, as described in more detail in the patent application DE 10 2005 009 207.1.
