- Figure 4 shows a cross section of another embodiment of the connection of two high-voltage plastic cables according to the present invention without using a coupling bush.
- Figure 5 shows a cross-section of a right-angled embodiment of the connection of two high-voltage plastic cables according to the present invention.
- Figure 6 shows a cross section of a right-angled embodiment of the connection of three high-voltage plastic cables according to the present invention.
- Figure 7 shows a cross section of a preferred embodiment of a connection of a high-voltage plastic cable to a high-voltage termi ⁇ nation according to the present invention.
- Figure 8 shows a cross section of an embodiment of the con- nection of a high-voltage plastic cable to a high-voltage switch or high-voltage transformer according to the invention, two plugged-in cables being assembled at an arbitrarily chosen angle to the centre line of the apparatus.
- the plug-in connection for two high-voltage plastic cables comprises an elastic sleeve insulator with stress-controlling body 8, an insulating body 9 and a conducting sheath 10.
- Received in the stress-controlling body 8 is a metal coupling bush 5 whose hole is in line with the hole of the stress- controlling body 8 and the insulating body 9, as a result of which a cylindrical cavity is produced through which the cable ends 1 can be pushed as far as the inside of the coupling bush 5.
- Each cable end 1 is stripped of its earthing screen 4 over a part of its length and of the insulating sheath 12 over a shorter part.
- a plug part 1 and a counter-plug part 15 are respectively welded to the bared conductors 13.
- Both plug part 1 and counter-plug part 15 comprise a cylindrical body which fits into the cylindrical cavity inside the coupling bush.
- the plug part is provided with a project ⁇ ing pin 2, while the counter-plug part is provided with a hole 16 for receiving the pin 2.
- Fitted between the pin 2 and the hole 16 are electrically conducting segments 19 for conducting the current.
- the cylindrical bodies of the plug part 14 and the counter-plug part 15 are provided with pawls 3 which can be pressed outwards by a spring 17.
- the pawls snap into annular recesses 7 in the coupling bush 5. This achieves an electrical connection and a strong mechanical coupling of the cable ends to the sleeve insulator and to each other.
- a plug pin part 14 or a counter-plug part 15 is welded to the conductor 1 of the two cable ends and the extruded earthing screen 4 is removed from the cable over a certain length of the cable end. Then one of the cable ends thus prepared in advance is inserted into the passage 11 of the sleeve insulator until the pawls 3 are pressed into the respective recess 7 of the coupling bush. Said cable conductor is then elec ⁇ trically and mechanically connected to coupling bush 5 and said cable end is positioned with an accuracy of + 1 mm with respect to the sleeve insulator.
- the diameter of the cable end plugged in, from which the earthing screen 4 has been removed is necessary for the diameter of the cable end plugged in, from which the earthing screen 4 has been removed, to be greater than the inside diameter of the passage 11 of the sleeve insulator so that, when the cable end is plugged into the sleeve insulator, the sleeve insulator stretches a little and lies as a close fit against the processed cable end.
- the second cable end is now plugged in so far that 1 to 2 cm of the cable insulation is situated in the passage of the sleeve insulator.
- the cable passage is sealed off from the outside air.
- the second cable end is also electrically and mechanically precisely connected to the coupling bush and a cur- rent-conducting connection between the two conductors of the cable ends is brought about because, at the same time, the plug part is plugged into the counter-plug part.
- the conducting sheath of the sleeve insulator 10 is connected in an electrically conducting manner to the earthing screen 4 of the two cables.
- the moisture-repellent and mecha ⁇ nical protection layers are provided over the sleeve insulator with .
- the plugging-in of the preprocessed cable ends lasts appro ⁇ ximately 30 minutes.
- the plug-in connection and the method accord- ing to the present invention have now been carried out a few times with a prototype of a sleeve insulator, followed by the standard type-approval tests, which have been successfully passed.
- the total costs of an installed connection according to the invention are lower than embodiments hitherto known as a result of saving in man costs, civil engineering work relat ⁇ ing to installation areas, and line surveillance costs, and because the voltage testing after installation is unnecessa ⁇ ry; 8. it is possible, in a simple manner, to connect two cables which differ in conductor section and insulation dimensions with a sleeve according to the invention.
- no electrically conducting coupling bush is used.
- the plug part 14 is locked to the counter-plug part 15 with the aid of a pawl construction in which the pawls 3 and the spring 17 are situated in the plug part, while the counter-plug part is provided in this case with recesses 7 for receiving the pawls.
- Said pawl construction is fitted in a thickened part of the plug pin so that the current passage is not disturbed at the segments 19.
- Figure 5 shows a sleeve insulator according to the present invention with which a right-angled connection can be brought about.
- the coupling bush 5 is provided with a closed middle part 20 as in the embodiments according to Figures 2 and 3.
- This right-angled connection according to Figure 5 has the impor ⁇ tant advantage that use of high-voltage cables is possible in limited spaces. Space-requiring cable bends can hereby be avoided. Angles other than the right-angled connection according to Figure 5 are also obviously possible.
- connection of which the cross sections are given in Figures 1 to 4 inclusively, with another method.
- the method is as follows. A sleeve insulator in the stretched state is pushed over one of the cables. Then the electrical and mechanical coupling between the cable ends is brought about with appropriate means. If it has a space in the stress-controlling body 8 for the coupling bush 5, the sleeve insulator is then brought to the cor ⁇ rect position around the coupled ends and the means with which the sleeve insulator has been stretched are removed. After that, the sleeve insulator fits closely onto the processed cable ends and the coupling bush 5, and the connection according to Figure 1, Figure 2, Figure 3 or Figure 4 is achieved.
- Figure 7 shows a cross section of the plug-in connection for a high-voltage plastic cable in a high-voltage outside termination.
- An elastic insulator is assembled in a mechanically strong and leak-tight manner on a metal foot plate 25 in a ground plate of the outside termination.
- said elastic insulator is identical to the sleeve insulator for connecting two high-voltage plastic cables according to Figures 1- 5.
- the shape of the insulating body is different and a part of the insulating body is not provided with the conducting sheath 10.
- the end of the conducting sheath 10 is rounded off at 23. At this point, the diameter of the insulating body is greater. This rounding 23 at the end of the conducting sheath, and the thickness and the length and conical shape of the insulating body at the termination side are dimensioned at the required insulation level of the termination structure.
- connection-rod of the termination insulator to the top of the termination and the preprocessed cable end are plugged in in the same manner as in the connection of two high-voltage cables as described above. It is also possible to test the complete ter ⁇ mination, with porcelain insulator 24 and filling medium, with high voltage before delivery. The same quality assurance level is hereby achieved as in the connection of two high-voltage plastic cables according to the invention.
- Figure 8 shows a section of a plug-in connection for two high-voltage plastic cables in a diagrammatically shown high-vol ⁇ tage switch 25.
- the elastic insulator is assembled in a mechanical ⁇ ly strong and leak-tight manner on the footplate of the diagram ⁇ matically shown switch compartment 11.
- the shape of the elastic insulator is in principle the same as the elastic insulator which is used in the outside termination of Figure 7.
- the insu ⁇ lator in Figure 8 is constructed in a manner such that two cables 1 can be plugged in at an angle to the axis of the breaker tank, and in practice this may be space- and cost-saving.
- the end pieces of the insulator are of identical construction as in the case of the insulator for the outside termination.
