Definitions

  • the invention relates to a voltage limiter, in particular to a three-pole voltage limiter with three connection points, in particular for use in a surge arrester magazine.
  • a voltage limiter of the generic type is previously known from DE-A-30 14 796, which is designed as a three-pole voltage limiter or double arrester.
  • the double arrester has three connecting legs, two of which connecting legs are connected to the two outer pole sides located on the end faces of the voltage limiter.
  • the middle connection leg is connected to the central pole side, which acts as the opposite pole for the outer pole sides.
  • the two-way arrester is inserted into a surge arrester magazine, which has a centrally arranged earth rail and plug elements arranged on both sides of the earth rail.
  • the middle connection leg is inserted into the earth rail and the two outer connection legs are inserted into the plug elements.
  • the plug-in elements are connected in a known manner to tabs which are led out of the housing of the surge arrester magazine. These tabs are connected when the surge arrester magazine is plugged into terminal strips with contact elements arranged there, on which cable wires are contacted. Each plug element is thus in electrical connection with a cable wire.
  • the current from the cable core through the plug elements from the outer pole side to the middle Pole side, derived to the middle connection leg and to the earth rail.
  • the invention is therefore based on the object of safely inserting the voltage limiter into the surge arrester magazine without bending the connecting legs and of giving the voltage limiter a stable position in the surge arrester magazine.
  • the voltage limiter is accommodated in a device which gives the voltage limiter in the surge arrester magazine a stable position and ensures that the connecting legs of the voltage limiter are not when the voltage limiter is inserted into the plug receptacle to be damaged.
  • the guide webs provided according to claim 6 ensure a secure supply of the connecting legs when inserted into the plug elements of the surge arrester magazine.
  • the voltage limiter 10 consists of a rectangular housing with three connecting legs 12, 13 arranged on the bottom side 11 of the housing.
  • the connecting legs 12, 13 are arranged in a row one behind the other, the middle connecting leg 13 being exactly centered on the two end faces of the voltage limiter 10 is arranged. All three connecting legs 12, 13 are each electrically connected to an electrical pole inside the voltage limiter 10.
  • the plug receptacle 1 shown in Fig. 1 consists of a rectangular housing body made of plastic.
  • the plug receptacle 1 has a free space 3 inside, the inner contour of which corresponds to the outer contour of the surge arrester 10.
  • On the bottom side 4 of the socket 1 are As also shown in FIGS.
  • FIG. 2 shows a surge arrester magazine 16 with a voltage limiter 10 inserted, which is accommodated in the plug receptacle 1.
  • the surge arrester magazine 16 has a centrally arranged earth rail 14 which is fork-shaped in cross section.
  • Upright plug elements 17 are arranged in the housing of the surge arrester magazine 16 on both sides of the earth rail 14 and are connected to plug tongues 20 which extend out of the housing.
  • the tongues 20 are connected to contact receptacles arranged in the terminal block.
  • the contacts are made in one piece with insulation displacement contacts to which cable wires are connected.
  • the plug receptacle 1 is first inserted from above into a corresponding chamber 21 of the surge arrester magazine 16 until the position shown in FIG. 2 is reached.
  • 8 shows the surge arrester magazine 16 in a plan view, the chambers 21 which are open at the top being recognizable lying side by side.
  • 8 shows a plug-in receptacle 1 inserted into the chamber 21 in the left-hand chamber 21.
  • the inner contour of the chamber 21 corresponds to the outer contour of the plug receptacle 1.
  • the voltage limiter 10 is inserted from above into the plug receptacle 1, here the connecting legs 12, 13 of the voltage limiter are inserted into the openings 5, 6 of the plug receptacle 1 until the connecting legs 12, 13 are in electrical connection with the earth rail 14 and Plug elements 17 are brought.
  • the two guide webs 2 give the two outer connecting legs 13 a guide so that the connecting legs 13 can be fed exactly without damage.
  • the voltage limiter 10 has a stable position after being inserted into the plug receptacle 1, since the housing body of the voltage limiter 10 is completely enclosed by the plug receptacle 1.
  • the voltage limiter 10 can also be equipped with a thermal protection 15, as is shown in particular in FIGS. 3 to 5.
  • the thermal protection 15 consists of a U-shaped bow spring, the first leg end 18 makes a contact connection with the central connecting leg 12 and the second leg end 17 is kept at a distance from the outer connecting legs 13 by a melting element 19.
  • 18 holding elements 22 are provided on the leg ends, which abut the bottom side 11 of the voltage limiter 10 and fasten the clamp spring to the voltage limiter 10 by clamping.
