Definitions

  • the present invention relates to a hood for covering the head of an insulating candle, which is arranged between the medium-voltage terminal of a power supply unit and a substantially vertically projecting from its connecting cable.
  • the medium voltage of a power supply unit including, for example, transformers, choke coils or the like, are voltages of 10/20/30 kv.
  • the insulation candles used in this case have an inverted funnel-shaped head part made of brass, on which there is an upwardly extending clamping bolt, which serves to fasten the connecting cable.
  • the clamping bolt is provided with an external thread, so that the connecting cable can be plugged with a suitably drilled cable lug and screwed by means of a pair of counter-acting hex nuts.
  • Object of the present invention is to provide a hood for covering the electrical connections between the insulating plug and cable in the medium voltage range, which is not only produced by simple means, but also provides a useful supplement to existing power supply units in terms of isolation functions.
  • hood is an all-round enclosure of the principally standardized connection connections between the insulation plug and connecting cable, which are used in the medium-voltage range of power supply units.
  • the hood consists - viewed in the installed position of the insulating candle from - in principle from a cylinder to the other hand, funnel-shaped sheathing area of is slipped over the top of the insulating candle and to which a diameter equal to smaller cylindrical tube-shaped area connects, the cylinder axis first coaxially with the longitudinal axis of the insulating candle coaxially before it is then finally bent by almost 90 ° to itself snug around the external insulation of the connection cable behind the connection point between the connection cable and the head of the insulation plug.
  • the invention has recognized that there are virtually no differences in diameter between the foot of the clamping bolt and the insulation of the connecting cable, so that in a simple way, the sheathing, which provides the hood for the connection point, composed of the reverse cylinder-funnel-shaped sheathing, at which adjoins the cylinder tube angled at 90 °.
  • the cylinder tube may have a rectangular, square or circular cross-section.
  • the hood can thus, assuming soft elastic material, simply slipped over the junction.
  • the area between the angled cylinder tube and the inverted cylindrical to funnel-shaped sheath region between its, the right angle enclosing legs are severed by a Wandungsschlitz, so that the hood are simply pulled under opening of Wandungsschlitzes over the junction can.
  • this development offers the possibility to provide in the region of the wall slot two flange-like lobes, which, lying basically parallel to each other, lie directly opposite each other in the position of use of the hood.
  • the flange-like lobes may conveniently between the open end of the cylinder tube, which ends above the insulation of the connecting cable and extend in the use position downwardly open end with the large diameter of the cylindrical to funnel-shaped sheath region, from where they are practically over the entire length of the Wandungsschlitzes initially extend either toward the attachment point of the angled cylinder tube or towards the smaller diameter of the funnel-shaped sheath region and extend from there to the inner wall enclosing the right angle of the cylinder tube.
  • the hood is made in one piece from a soft plastic, e.g. a soft PVC, so that the desired tightness functions are met.
  • a soft plastic e.g. a soft PVC
  • hood is particularly appropriate to make the hood from a liquefiable under temperature plastic, which is solidified by gelling at a predetermined higher temperature, which is above the liquefaction temperature.
  • This manufacturing method is particularly suitable for the production of large quantities at low cost, because the resulting mold costs keep within narrow limits.
  • a hood produced in the dipping process subjected to a further temperature treatment, which takes place at a temperature above the temperature necessary for gelling the plastic, can produce a mirror-smooth surface, so that the hood receives a pleasing and professional appearance.
  • the hood can also be deep-drawn, sprayed or produced by other conventional methods.
  • the figures show a hood 1 for covering the head 2 of an insulating candle (not shown).
  • the insulating candle has a head part 3, usually made of brass, which is followed by a clamping bolt 4 connects upwards.
  • the clamping bolt 4 is designed here as a screw bolt, at the upper end of the connecting cable 5 is attached via a cable lug 6 and the hex nut connection shown.
  • Such connections are used at the medium-voltage terminals of power supply units and are known in principle or standardized in the art.
  • the head part 3 is circumscribed by an inverted funnel whose large diameter faces the insulating candle, while the smaller diameter points towards the clamping bolt 4.
  • the hood forms a cylindrical to inverted funnel-shaped sheathing region 7, which serves for insulation sheathing, also for insulation against moisture, of the head 2 of the insulation candle.
  • connection point 10 practically defines the point where the cylindrical tube-shaped region 9, which initially runs parallel to the funnel longitudinal axis 11, turns by the right-hand angle 13 in order to extend parallel to the cable longitudinal axis 12 from there. Deviating from Figure 1, it may be expedient according to Figure 7, when the connection point occupies a sufficient distance from the inner wall of the hood 1.
  • the open end 14 of the angled cylinder tube which laterally adjoins the cylindrical tubular portion 9 but anyway so far in the direction of the connecting cable 5, that the connection point 10 is covered together with the cable lug 6, because the open end 14 only in the area the insulation, which surrounds the connecting cable 5, ends and snuggles around there around the insulation of the connecting cable 5.
  • the cylindrical tube-shaped area can be according to Figure 7 over its entire length of constant inner and outer diameter or cross-section.
  • the figures show a further education, in which the cylindrical tube-shaped area between its, the right angle spanning legs has a Wandungsschlitz 15, so that the hood can be easily pulled over the electrical connection with spreading of the wall slot.
  • two flange-like lobes 16a, b are provided here, which are provided parallel to one another within the right angle enclosed by the longitudinal center line.
  • the flange-like tabs 16a, b extend from that end of the hood, which has the large diameter for superposition of the head part 3 to the open end 14 of the cylindrical tube-shaped area and can be penetrated by a connecting screw 17 or the like, so that an unauthorized removal of this Hood 1 is not possible.
  • the hood is suitably made in one piece from a soft plastic and everywhere of the same wall thickness.
  • the hood from a processable in the dipping process plastic. It is a plastic which is liquefiable at a predetermined temperature and which gels at a predetermined higher temperature.
  • the positive model is withdrawn from the liquified plastic and expediently exposed by further treatment at a temperature above the predetermined higher temperature at which gelling begins, so that the outer surface of the hood is mirror-smooth.
  • the positive model is on its located between the legs of the right angle side, where later the flange-like tabs are formed, provided with a collar 18, so that again the wall thickness of the flange Rag in the sense of uniform growth of the hood 1 is possible.
