Definitions
- the invention is based on a method for producing a High-voltage bushing according to the preamble of claim 1. Mit this method, column-shaped bushings are made, which the implementation of a high-voltage conductor by a grounded housing wall, for example, a transformer serve.
- Such Bushings each have a hollow, cylindrically symmetrical Outdoor insulator, on one end face of a high voltage potential feasible bushing head and at the opposite arranged another end face a grounding feasible lead-in foot is attached. Further, the implementation includes a longitudinal axis of the cylinder through the Outdoor insulator guided draft tube and one attached to the draft tube, field-controlling insulating body.
- the invention adopts methods for the production of High-voltage bushings reference, as the patent applicant already used for many years.
- a mounting flange executed passage foot one of porcelain or a dimensionally stable Plastic manufactured outdoor insulator and a feedthrough head with a Compression spring mounted in sequence on a draft tube.
- This draft tube carries a field-controlling insulating body on which the bushing foot is supported becomes.
- the feedthrough head With the help of a clamping tool, the feedthrough head with Preload supported supported on the outdoor insulator. On that by the Guided head and an externally threaded end of the Drawbar is a nut until it stops at the feedthrough head screwed.
- the invention as defined in the claims solves the problem Specify method of the type mentioned, which makes it possible High voltage bushings with different dimensions and To manufacture requirements in a particularly economical manner.
- the clamping element With the help a guided in a threaded through hole of the head plate screw to attach the head flange.
- the clamping element can then during assembly of the Implementation can be very easily operated.
- the clamping element largely independent of the size of the bushing head and can at the production of arbitrarily dimensioned bushings are used.
- the preloaded bushing head with a s.der Clamping plate provided internal thread on an external thread of the pulling body unscrew and to the stop on the outdoor insulator on the tensile body seswinden. It can be the one for traditional manufacturing necessary and therefore existing external threads are used and at the same time accounts for the production of the pre-assembled implementation otherwise necessary tools.
- the mating thread of the screw is designed as a through hole, can the inside of the bushing after removing the screw over this Be filled with insulating hole. Attaching an additional Filling opening for the insulating can be omitted.
- a secure completion of the implementation inside is achieved when the Thread through hole after filling the insulation with a suitable sealing screw is closed.
- the high-voltage bushing shown in Fig. 1 is a kind of Column executed and has a hollow, cylindrically symmetrical outdoor insulator. 1 on.
- This insulator is made of a dimensionally stable, weather-resistant material, preferably a plastic based on a tube made of a fiber-reinforced Composite material and a silicone shielding or a porcelain, manufactured. He wears one on his upturned face High voltage potential of leadable metal bushing head 2.
- the Open-air insulator from a metal feed-through foot that can be guided to ground potential 3 worn.
- a cylindrically symmetrical metal traction body 5 out which - as shown - can be designed as a tube 5 or as a solid bolt.
- the tension body of a recording high-voltage cable end which with a cable stud at the top End of the drawbar is electrically conductively attached. Is the tension body as a bolt formed, this pin can otherwise flow in the cable end current to lead.
- the insulating body 6 has an upper predominantly cylindrical and a lower predominantly conical section on.
- the cylindrical one Section is located inside the outdoor insulator 1 and serves the control of the electric field during operation of the passage through the drawbar. 5 guided, high-voltage conductor in the area of the open-air insulator. 1 and the bushing foot 3.
- the conical section is in operation of the Execution in one with the feedthrough foot 3 electrically conductive connected housing, such as a transformer, and arranged controls the electric field of the not shown in Fig.1, high-voltage conductor in housing interior.
- the two ends of the drawbar 5 are made led out inside the implementation.
- an external thread 51 inserted, which cooperates with two in Fig.1 not designated internal threads for a clamping element 21 of the feedthrough head second and for a mounting device 8 for holding a final bolt of the in operation the implementation through the drawbar 5 drawn, high-voltage Current conductor.
- a spherical Control electrode attached, which is the homogenization of the electric field of the drawn in the drawbar 5 conductor is used.
- the structure of the prestressed bushing head 2 is shown. It can be seen in the head flange 22 of the feedthrough head two Threaded through holes are recessed, in each one of two Mounting screws 23 is guided, and the clamping element 21 has a on the Top flange resting plate spring 24 and a plate spring 24th compressed clamping plate 25 on.
- the clamping plate 25 does not contain two designated aligned in the direction of the axis 4 bushings, in which in each case one of the two mounting screws 23 is rotatably mounted. In the Clamping plate 25 is further an internal thread 26 is inserted.
- a remaining inside the implementation and essentially from the Insulating body 6 and the inner walls of outdoor insulator 1, head flange 22 and provisionssfuss 3 limited cavity 9 is for dielectric reasons with an insulating agent, such as a silicone oil filled.
- This insulating agent can after complete removal of the two mounting screws 23 in a simple Way through one of the threaded through holes are filled.
- an insulating agent such as a silicone oil filled.
- This insulating agent can after complete removal of the two mounting screws 23 in a simple Way through one of the threaded through holes are filled.
- For the Tightness of the cavity 9 provide in Figure 2 unspecified gaskets, between the draft tube 5 and head flange 22 and not shown in the figures Sealing rings between outdoor insulator 1 or insulator 6 and head flange 22nd orêtsfuss 3.
- the present in the cavity 9 air can in this case the other of the two threaded through holes are removed. After this Filling the cavity 9, the threaded through holes can Sealing screws are closed
