Definitions
- the invention relates to an insulator according to the preamble of claim 1 and an arrangement according to claim 11.
- Composite long-bar insulators are, for example, from the
- Shields are provided for extending the creepage distance.
- End fittings can have a variety of different shapes at their end facing away from the housing. These shapes are for connecting or hanging the insulator
- Clapper, pan, joint fork, joint bracket, Y-fork and eyelet Clapper, pan, joint fork, joint bracket, Y-fork and eyelet.
- An isolator is made with the help of protective rings
- Such protective fittings are connected to the isolator via additional fittings, i.e. connected to an end fitting. These connections between insulator and additional fittings
- Faucets are usually flexibly stored to none
- a line arrester with an external spark gap To transmit bending stresses to the insulator.
- a line arrester with an external spark gap For example, a line arrester with an external spark gap
- the object of the invention is to provide an isolator which can be connected to an item of equipment in a particularly simple and reliable manner.
- the invention solves this problem by an isolator according to claim 1.
- the invention addresses the problem that there are applications in which storage of the equipment on the insulator should be fixed in a motionless manner. For example, this is the case if the distance between the protective rings and the center of the insulator is to be constant or if other protective devices such as a line arrester are to be installed.
- a movement-free fixation denotes an attachment without degrees of freedom.
- Spark gaps are all degrees of freedom to remove the length of the spark gap even when the
- Isolators e.g. due to vibrations due to wind
- the valve is geometrically designed so that the tab lies flat in the fork and is thus fixed. This requires a high degree of accuracy in production. In addition, this design is never free of movement.
- the invention solves this problem by the one-piece design, in which the end fitting with the
- Connecting device is combined. Consequently, two components are replaced by a single component, which removes all degrees of freedom of this connection. The position of the attached components is fixed. Another advantage is that material is saved and assembly effort is reduced.
- the isolator is a long-rod isolator. This is an advantage because long-rod insulators have been tried and tested and widely used.
- the connecting device has a
- the contact section has at least one recess for fastening the additional equipment.
- the contact section has at least two boreholes for fastening the additional equipment. This is an advantage because the holes can be used to insert two screws with nuts.
- the connecting device has a suspension section with a means for suspending the insulator. This is an advantage because insulators are often used on pylons for high-voltage overhead lines. A hanging attachment is common
- the suspension section has at least one of the following shapes: clapper, pan, joint fork, Articulated strap, Y-cable, eyelet. Consequently, numerous different suspension means can be used as needed
- the end fitting with the connecting device consists essentially of metal. Steel or aluminum is preferred. This is an advantage because the use of a metal end fitting is inexpensive to manufacture and it is robust and durable.
- Isolator invention is the end fitting with the
- the object of the invention is a
- Figure 2 shows a second known connecting device
- Figure 3 shows a known arrangement with two isolators
- Figure 4 shows another known arrangement with a
- FIG. 5 is a detailed view of the known arrangement
- FIG. 6 shows an embodiment of the invention
- Figure 7 shows an embodiment of a
- FIG. 1 shows a connecting device 1 with a first eyelet 71, a contact section 2 for attaching additional operating means and a second eyelet 3.
- the eyelets 3, 71 are designed as essentially flat metal rings, the planes of the essentially flat metal rings relative to one another stand vertically.
- the eyelets 5, 71 are arranged in one plane.
- Connection device 1 according to FIG. 1 allows
- Connecting device 4 arranges mast suspension and insulator in the same orientation and thus also that
- FIG. 2 shows an arrangement 6 known in the prior art with two long rod insulators 7, 8.
- the long rod insulators are connected to protective armatures 11, 12 via connecting devices 22, 24 which are attached to the respective end fittings 17, 18 of the insulators 7, 8.
- the protective fittings 11, 12 are corona rings and have webs 15, 16.
- the connecting devices 22, 24 are also each connected to mast fasteners 13, 14.
- the respective end fittings 21, 22 are in turn over
- Corona rings 9, 10 connected. To prevent the suspended insulators 7, 8 from striking against one another, a
- Spacer 27 is provided in a substantially Y-shaped arrangement. This spacer 27 is in turn connected via a connecting device 28 to a conductor fitting 29 for connection to a conductor cable (not shown).
- FIG. 4 shows a known arrangement 30 with a
- the long rod insulator 31 is over
- Connecting devices 36, 37 according to the invention are each connected to two arms 32, 33.
- the arms 32, 33 each carry a surge arrester and a spark horn 34, 35, so that a separation distance of length D in air is provided between the spark horns 34 and 35.
- This arrangement provides a so-called “externally gapped line arrester (EGLA)".
- FIG. 5 shows a detailed picture in the area of
- connection device 37 according to the invention.
- the arrester on the arm 33 is via a base plate 51, which by means of a
- Screw 52 is attached, connected. On the
- Base plate 51 is at a perpendicular angle to this
- Base plate 51 a fastening bolt 53 out.
- This has two holes for receiving screws 54, 55.
- a bore is designed as an elongated hole 56, so that each after the screw 55 has been positioned in the elongated hole 56, the base plate can be turned in a plane that is perpendicular (to the ground). This makes it possible to adjust and fix the length of the separating section D.
- the arrow 57 indicates the direction of rotation along the recess defined by the elongated hole 56.
- the screws 54, 55 fix the base plate 51 and the
- the holding web 47 has a kinked in the direction of the base plate 51
- connection device 37 provides a suspension for the end fitting 38 of the insulator 31. This suspension is formed in that the one 39 at the end of the end fitting 38 can be inserted into a recess 40 in the connecting device 37.
- the fork 39 flatly encompasses the connecting device 37, which is essentially in the form of a flat metal piece, so that with a corresponding one
- Connecting device 37 also has an eyelet 49 for gripping a mast suspension 50.
- Figure 6 shows an inventive
- the connecting device 60 of a long rod insulator 31 has an end fitting which integrally contains the connecting device for attaching further equipment and for mast suspension.
- the end fitting has an approximately center
- the contact section 61 has two
- the device according to FIG. 5 is omitted. This saves material and costs.
- FIG. 7 shows the end fitting according to the invention
- the eyelet 64 of the connecting device is connected to a mast suspension 65.
