Definitions
- the invention relates to a high-voltage system with a metallic encapsulation housing which encloses at least one high-voltage conductor and with a device for transmitting electromagnetic signals, in particular for communication and / or for monitoring the high-voltage system, which has a probe arranged in the interior of the encapsulation housing.
- Such a high-voltage system is, for example, from the technical article "PD Signal Propagation in GIS Considering Frequencies up to GHz", 8th Int. Sy p. High Voltage Eng., Yokohama, Japan, page 93ff and from the technical article “A Continuous UHF -Monitor for Gas-insulated Substations ", IEEE Trans. El. Vol. 26-3, June 1991, pp. 469ff, and from the article "Broadband Couplers for UHF detection of partial discharge in gas-insulated substations", IEE Proc. Meas. Technol., Vol. 142, No. 3, May 1995, page 237ff.
- a power line is known from WO 95/29553, with a sensor enclosed by the cable jacket.
- Various cable properties such as voltage drop, temperature or pressure are to be monitored there by the sensor.
- disk shaped probes used as antennas or as capacitive voltage dividers.
- the present invention is therefore based on the object of creating a high-voltage system of the type mentioned at the beginning with a device for transmitting electromagnetic signals, with a probe which is as broadband as possible.
- the probe has a conical body (cone antenna), the base of which faces the high-voltage conductor and the cone tip of which faces the inner wall of the encapsulation housing.
- the conical body forms a cone antenna known per se within the encapsulation housing, with the broadband frequency characteristic known from this.
- the geometric radiation characteristic of the cone antenna favors radiation via the cone surface, i. H. if necessary along the encapsulation housing walls. If the cone antenna is arranged within a cylindrical tubular encapsulation housing, the signals emitted by the cone antenna predominantly propagate in the axial direction of the tube. Signals propagating in this direction from other sources are picked up by the cone antenna with high broadband and high sensitivity.
- the cone antenna can be used to effectively monitor the high-voltage system, for example with regard to signals from partial discharge processes.
- the capacitive coupling of the cone antenna via the cone base to the high-voltage conductor is particularly effective.
- Capacitive voltage tapping (operation as a capacitive voltage divider) and antenna operation can alternatively or simultaneously take place depending on the wiring.
- the cone antenna it is also possible to transmit or receive communication signals by means of the cone antenna, so that communication within the encapsulation housing is possible over large distances of, for example, a few hundred meters.
- the interrogation of surface wave elements by means of signals emitted by the cone antenna is also conceivable.
- the cone antenna is arranged in a housing connector attached to the circumference of the encapsulation housing, an arrangement can also be advantageous in which the cone axis of the cone antenna is arranged parallel to the plane of the encapsulation housing wall and thus perpendicular to the direction of the housing connector.
- An advantageous embodiment of the invention provides that the conical body has a cone opening angle of approximately 90 °.
- a cone opening angle of approx. 90 ° leads to a base resistance in the range of 50 ohms, which then corresponds to the characteristic impedance of the coaxial cable normally used. This enables loss-free coupling of the cone antenna to a coaxial line.
- a further embodiment of the invention provides that the conical body is arranged in a radial bulge of the encapsulation housing in such a way that the base area of the conical body is fitted into the imaginary continuation of the inner contour of the bulge adjacent regions of the encapsulation housing.
- This embodiment of the invention enables the radiation and reception of electromagnetic signals in the radial direction with respect to the cone antenna, without the conical body protruding too far into the interior of the encapsulation housing. This reduces the risk of electrical arcing from the high voltage conductor to the cone antenna.
- the conical body can, for example, be arranged in a connecting piece of the encapsulation housing. This facilitates both the maintenance of the cone antenna and the gas-tight passage of the coaxial cable. For reasons of field design and to avoid partial discharges, it may be advantageous for the conical body to be rounded on the circumference of its base area.
- a further advantageous embodiment of the invention provides that the conical body is supported in the area of its lateral surface by a plurality of insulating supports.
- This construction enables the conical body to be securely fastened without impairing the radiation characteristics. Secure fastening is necessary insofar as strong vibrations can act on the high-voltage system during transport or in the event of an earthquake or during a switching operation.
- Another advantageous embodiment of the invention provides that the conical body is hollow and divisible parallel to its base.
- the body can also be designed as a one-piece, hollow casting, in which the base area is left open. This allows inexpensive production.
- the conical body is held in the region of its cone tip in an insulating body fastened to the encapsulation housing.
- Such a fastening of the conical body represents a particularly low construction and assembly effort.
- the cone tip of the conical body can advantageously be connected directly to the inner conductor of a coaxial line. No electrical adaptation elements or symmetry elements are required for the connection between the antenna and the coaxial line. It can only be provided that for the mechanical coupling a plug connected to the tip of the conical body is provided, which can be inserted into a gas-tight socket fitted in the encapsulation housing wall, which is connected to the coaxial line on the outside of the encapsulation housing.
- FIG. 1 shows schematically the inside of an encapsulation housing of a high-voltage system with a conical body
- FIG. 2 shows the conical body in cross section.
- a conical body 4 is arranged, the base 5 of which faces the high-voltage conductor 3, while the tip 6 faces the encapsulation housing wall 7.
- the encapsulation housing 1 has a bulge 8, in which the conical body 4 is arranged in such a way that its base area 5 is roughly fitted into the continuous contour 9 of the encapsulation housing 1, shown in broken lines.
- the cone-shaped body 4 is rounded on the circumference of its base area 5 for reasons of field design and rollover security.
- the angle between the conical surface 10 and the encapsulating housing wall 7 is approximately 45 ° all round.
- the cone angle 11 of the conical body 4 is approximately 90 °.
- the geometrical radiation characteristic of the conical body 4 forming a cone antenna by the wave fronts 12, 13, 14, 15 is indicated in FIG. These wave fronts spread out at some distance from the cone antenna in the axial direction of the cylindrical encapsulation housing 1. In the illustration shown in FIG.
- the wave fronts are shown when the antenna is operating.
- correspondingly propagating electromagnetic signals can also be received by the cone antenna, which can be emitted, for example, by partial discharges in a remote insulating material support 16 if, for example, a particle 17 has accumulated on its surface.
- the then generated TE signals are shown by the wave fronts 18 as examples. These are detected by the cone antenna 4 with high sensitivity.
- FIG. 2 shows that the conical body 4 is divided into an upper part 19 and a lower part 20.
- the lower part 20 is supported and fastened to the encapsulation housing wall 1 by means of insulating supports 21, 22.
- the lower part 20 of the conical body 4 is screwed to the insulating supports 21, 22 by means of screws 23.
- the upper part 19 of the conical body 4 can be placed and fixed, for example by means of a press fit or a screw connection.
- the tip 6 of the conical body 4 ends in a pin 24 which is held in a corresponding receptacle 25 in a bushing of the encapsulation housing wall 1.
- From there there is a conductive connection to the coaxial line 26, the outer conductor of which is connected to the encapsulation housing 1, while the inner conductor is conductively connected to the conical body 4.
- the characteristic impedance of this coaxial line 26 is 50 ohms.
