Definitions
- the invention relates to an electrical bushing with a bushing conductor and an insulating body surrounding the bushing conductor, with a fastening flange anchored in the insulating body, on the inner circumference of which a shielding body controlling the electric field is arranged, and with a capacitive voltage tap provided for the operation of a display device , consisting of a tapping electrode concentrically surrounding the lead-through conductor within the insulating body and a connecting element connected to it and accessible on the outside of the insulating body.
- the field-controlling shielding body which has a sleeve-shaped section, is designed here as a one-piece molded body made of a rubber-elastic, electrically conductive material. It is cast in the insulating body and is concentric with the feed-through conductor.
- the tap electrode consists of a metallic ring, for example made of wire, connected to a support device which is centered by the sleeve-shaped section of the shielding body.
- Several support members emanate from the ring and lie against the outer jacket of the sleeve-shaped section of the shielding body with the interposition of electrical insulation.
- the entire support device is fixed coaxially to the feed-through conductor on the shielding body.
- the insulation consisting of strips of film is glued to the support members.
- the connecting element which is designed, for example, as a contact tab, is fastened to one of the support members.
- the invention is therefore based on the object of improving and simplifying the electrical feedthrough with regard to its tap electrode.
- the tap electrode is designed as an insulating ring body provided with an outer conductive layer, which has at least three support feet which extend over the shielding body, one of which supports the connection element connected to the conductive layer.
- FIG. 1 shows an elevation of an electrical feedthrough with cast-in electrode for a capacitively coupled voltage display system
- FIG. 2 shows a tap electrode designed as a ring body in plan view
- FIG. 3 shows the ring body according to FIG. 2 as a sectional illustration according to section line A-B
- FIG. 4 shows a section IV-IV according to FIG. 3.
- FIG. 1 shows an electrical feedthrough which is made up of an insulating body, one of the insulating Body 3 surrounding lead-through conductor 2, a fastening flange 4, a field-controlling shielding body 5 and a capacitively coupled tapping electrode for operating a voltage display device.
- the structure and the arrangement of the shielding body 4 and the fastening flange 5 in the bushing 1 are unchanged from the prior art mentioned at the outset, on which the invention is based.
- the tap electrode is designed as an annular body 6 (see FIG. 2) made of plastic, which is connected to a conductive layer 7, e.g. a conductive lacquer, is provided and has at least three support feet 8 which extend over the shielding body 5.
- the one support leg 8 carries a connection element 10, which is accessible on the outside 9 of the insulating body 3, e.g. a contact lug for coupling the voltage display device.
- the support feet 8 are in cross-section and inclination to the longitudinal axis of the bushing 1 on the annular
- Shielding body 5 is adapted in such a way that, in the assembled state, there is a clamping fit of the ring body 6 on the shielding body 5 before the insulating body 3 is potted.
- the support feet 8 are provided with a collar 13 arranged all round. On the inside, the support feet have two sharp-edged or pointed projections 12 for anchoring in the shielding body 5 (see FIG. 3). Both Measures serve to securely anchor the tap electrode 6, 7, 8 in the insulating body 3.
