Definitions
- Isolator arrangement for an overhead line The invention is in the field of electrical engineering and relates specifically to an insulator arrangement for an overhead line.
- Such overhead lines are used in power transmission networks for the transport of electrical energy in the high voltage range.
- Individual rope-like conductors are usually to be fastened to masts by means of holding insulators.
- For the electrical protection of the overhead lines Kraftsabieiter be used in this context to dissipate overvoltages occurring, for example by lightning strike, to earth potential.
- Line arresters are used both in wireless technology and in conjunction with an external series spark gap, which isolates the Abieiter in normal operation, against switching overvoltages or even after an overload on the line.
- a line arrester with external series spark gap (English: externally gapped line arrester or EGLA) has a series connected to the diverter spark gap.
- One end of the line arrester is earthed at a grounding point of the transmission tower, at the other end there is a spark electrode, which forms a spark gap with a spark plug at the high-voltage end of the line insulator.
- the overhead line itself can serve as the high-voltage end of the spark gap.
- the present invention is based on the object to provide an insulator arrangement for an overhead line, which allows easy installation, even in the case of retrofitting.
- the invention relates concretely to an insulator arrangement for an overhead line, comprising a holding insulator for fastening an overhead line to a mast and an arm arranged parallel to the holding insulator
- a line arrester arrangement having a surge arrester electrically connected to ground potential and a spark gap connected in series with a first spark electrode connected to the overhead line and a second spark electrode connected to the surge arrester.
- the plinsableiteranssen has a mountable to the overhead line mounting insulator, wherein the first spark electrode to a first fastening device at a first end of the mounting insulator and the second spark electrode to a second fastening device at a second end of the mounting insulator is attached.
- the mounting insulator is preferably designed as a rigid long-rod insulator. He offers with the two fastening devices a holder for the surge arrester or the spark electrode.
- Each spark electrode may either be attached directly to one end of the fixture or the spark electrode is attached to one end of an over-surge arrester which in turn is attached to the fixture at its other end.
- the length of the mounting insulator determines the distance between the two spark electrodes and thus the spark gap.
- the mounting insulator thus forms together with the surge arrester and the spark electrodes a mechanically stable compact unit which can be easily attached to the overhead line via a holding device.
- the connection to the earth potential can be made via a ground line to the mast.
- the mounting insulator is designed as a long-rod insulator.
- the mounting insulator can be provided as a prefabricated product that can be produced industrially in large numbers for a low price.
- Such rod insulators usually consist of a glass-fiber-reinforced plastic material which is protected from the weather by a coating for weather protection in the form of, for example, a silicone material.
- the mounting insulator can advantageously have a lower mechanical stability than the holding insulator. As a result, the overall arrangement can be produced particularly inexpensively.
- a further advantageous embodiment of the invention provides that the first and / or second fastening device connects spark electrode or a surge arrester with the mounting insulator angle stiff.
- the angle-rigid attachment may comprise a pivoting device, which is an alignment of the spark electrode or the
- the invention can advantageously be configured in that the spark gap between the two
- Surge arrester is arranged.
- the two surge arresters are separated by the spark gap.
- Overvoltage arresters can be made shorter and thus subject to a lower bending load.
- Each of the surge arresters may then carry, for example, a spark gap spark electrode.
- the respective spark electrode is expediently arranged and fastened in each case to an end fitting of the surge arrester.
- an overvoltage arrester is fixed to each of the fastening devices with a first end fixed in an angle-rigid manner and at a second end each
- Surge arrester is arranged in each case a spark electrode.
- the function of the surge arrester is thus divided over two preferably similar parts.
- Each part consists of a surge arrester and a spark electrode attached to it.
- Each of the two parts is attached to one of the fastening devices.
- the surge arresters are each secured at one end to the fastening device with an angle.
- the spark electrodes are respectively arranged at the other end of the surge arrester and together form the spark gap.
- An advantageous embodiment of the invention can provide that at least one spark electrode rod-shaped, arranged at the end of a surge arrester and with respect to its longitudinal axis against the longitudinal axis of the
- Surge arrester is inclined.
- the two surge arresters are constructed identically.
- the two surge arresters are for example adjustable in their angles against each other, whereby the two surge arresters are for example adjustable in their angles against each other, whereby the two surge arresters
- Angular ratio of the rigid-shaped spark electrodes is adjustable and the distance between the spark electrodes to each other.
- the spark electrode is rotatable about the longitudinal axis of the surge arrester. If the spark electrodes are rotatable with respect to the longitudinal axis of the respective surge arrester to which they are attached, a spacing adjustment of the two spark electrodes to one another can also follow via a rotation of the spark electrodes.
- FIG. 1 shows a side view of a power pole with a section of an overhead line and an insulator arrangement according to the invention
- Figure 2 shows a detail of a device similar to in
- FIG. 1 shows in detail an overhead line mast 3 with a jib 20, which represents a horizontal arm for holding an overhead line 2.
- Such overhead lines 2 are designed, for example, as stranded stranded conductors for conducting electrical energy. It is common practice to hold such overhead lines 2 to the arms 20 of masts 3 by means of holding insulators 4.
- Such holding insulators 4 are usually made of porcelain or other inorganic material or else made of a material such as glass fiber reinforced plastic, and usually have screens to extend the creepage distance.
- an outer coating for example consisting of silicone, is usually provided, which forms the shielding.
- the holding insulators 4 must on the one hand carry the weight of the overhead line 2, on the other hand absorb the applied by the bracing of the overhead line forces. For this reason, such holding insulators 4 are generally of mechanically stable construction.
- a Dunsableiteran Mr 8 is electrically connected in parallel to the holding insulator 4. Both the holding insulator 4 and the Dunsableiteran Mr 8 are electrically connected between the overhead line 2 and the mast 3 to the ground.
- the dormitorsableiteran Mr 8 has the function, in case of overvoltages in the overhead line 2, for example, by lightning strikes, derive the overvoltage that has occurred to the earth.
- the plinsableiteran angel 8 consists of a mounting insulator 5, a surge absorber 9 and two

- a spark electrode 6 is fixed.
- a surge arrester 9 is attached to a second spark electrode 7.
- the intermediate space between the spark electrodes 6, 7 forms the spark gap 11.
- the mounting insulator 5 thus provides, on the one hand, an attachment possibility for the spark electrode 6 and the
- Surge arrester 9 sets at the same time over its length the distance of the spark electrodes 6 and 7 and thus the length of the spark gap 11 fixed.
- FIG. 2 further shows an alternative embodiment of the invention, with the mast being shown only in tearing with respect to FIG.
- FIG. 3 shows a more detailed illustration of the line arrester arrangement 8 from FIG. 2.
- the assembly insulator 5 is shown here as a long-rod insulator.
