Definitions
- the invention relates to a hollow insulator for high electrical voltages and to a method for producing such a hollow insulator.
- the invention relates to hollow insulators for air-insulated high-voltage devices or high-voltage components such as outdoor circuit breakers or outdoor bushings.
- Hollow insulators for high electrical voltages are often made of ceramic materials or composite materials such as fiber-reinforced plastics.
- Ke- ramische hollow insulators have a high mechanical Festig ⁇ ness, particularly against bending, on. However, be ⁇ is in a standing under a high gas pressure ceramic hollow insulator risk of bursting.
- Hollow insulators made of composite materials are mechanically less stable, but more resistant to bursting than ceramic hollow insulators.
- the invention has for its object to provide an improved hollow insulator for high voltages and a method for producing such a hollow insulator.
- a high-voltage electrical insulator comprises an insulating tube and a sheath of the insulating tube, made of a fiber-reinforced plastic, which bears against an outer surface of the insulating tube.
- the insulating tube is made for example of a ceramic material or a glass or a plastic.
- An inventive hollow insulator thus advantageously combines the mechanical stability of a ceramic, for example, egg ⁇ nem material or a glass or a plastic insulating tube made with the fiber-bursting ⁇ reinforced plastics.
- a hollow insulator according to the invention is therefore mechanically more stable than a hollow insulator, which is made of a fiber-reinforced plastic, and burst ⁇ safer than a hollow insulator, which is made for example of a ceramic material or a glass or plastic.
- An embodiment of the invention provides for an electrically insulating shielding arranged around the insulating tube and the sheathing.
- This embodiment of the invention is particularly advantageous in a use of the hollow insulator outdoors, in which it is exposed to changing weather conditions, in particular rainfall.
- a further embodiment of the invention provides at least ei ⁇ NEN arranged at one end of the hollow insulator flange with a ring extending around an insulator longitudinal axis of the hollow insulator flange collar. In this case, for example, at least one flange is connected to the insulating tube or to the sheathing. Flanges which are arranged at ends of the hollow insulator allow, advantageously a reliable and easy connection of the hollow insulator with further construction elements ⁇ .
- Hollow insulator for high electrical voltages is a Iso ⁇ lierrohr made, for example, of a ceramic material or a glass or a plastic and the insulating ⁇ pipe is coated with a fiber-reinforced plastic.
- the method enables the production of a hollow insulator with the advantages mentioned above.
- An embodiment of the method provides that the Iso ⁇ lierrohr is coated with the fiber-reinforced plastic, by a prefabricated fibrous mat to the iso ⁇ lierrohr around is arranged at least and a fiber mat is subsequently introduced by a vacuum impregnation art ⁇ material into the at least ,
- An alternative embodiment of the method provides that the insulating tube is coated with a fa ⁇ serverver prisonen plastic by the fiber-reinforced plastic is wet-wound or dry wound around the insulating tube around.
- Both of the aforementioned embodiments of the method allow the sheathing of an insulating tube made of a ceramic material with a fiber-reinforced plastic, wherein the advantageousness of one of these Ausgestaltun gene can depend on the materials used in each case for the production of the insulating tube and / or the sheath.
- a further embodiment of the method provides that a flange is arranged in front of the sheathing of the insulating tube at at least one end of the insulating tube.
- the at least one flange is connected to the insulating tube, for example by cementing.
- a flange may be arranged after the shell of the insulating tube at least one end of the order ⁇ sheathing.
- the at least one flange is connected, for example by an adhesive bond with the sheath.
- the single figure shows a sectional view of a hollow insulator 1 for high voltages.
- the Hohliso ⁇ lator 1 comprises an insulating tube 3, a sheath 5 of the insulating tube 3, a shield 7 and two flanges 9, 11th
- the insulating tube 3 is made of a ceramic material or a glass or a plastic such.
- the casing 5 is made of a turaver ⁇ reinforced plastic, for example of a fiber-reinforced molding resin such as epoxy resin and is applied to an outer surface of the insulating tube.
- the insulating tube 3 is covered with the fa ⁇ server reinforced plastic by a prefabricated fiber mat around the insulating tube 3 around is angeord- net at least and at least one fiber mat is subsequently introduced by a vacuum impregnation of the plastic used for the preparation of the hollow insulator. 1
- the insulating tube 3 is sheathed with the fiber reinforced plastic by thread winding the fiber reinforced plastic wet or dry around the insulating tube 3.
- the flanges 9, 11 are arranged at mutually opposite ends of the hollow insulator 1 and each have a ringför ⁇ mig about an insulator longitudinal axis 13 of the hollow insulator 1 dur- fenden flange collar 15 on.
- each flange 9, 11 is connected to an Au ⁇ . . 5
- the flanges 9, 11 are glued to the casing 5, for example.
- An alternative (not shown) embodiment provides that the sheath 5 surrounds only between the flanges 9, 11 extending portion of the insulating tube 3 and each flange 9, 11 is connected directly to the insulating tube 3.
- the flanges 9, 11 are cemented, for example, to the insulating tube 3.
- the shield 7 is made of an electrically insulating material, for example of a silicone.
- the Be ⁇ shielding 7 is disposed on an outer surface of the casing 5 between the flanges 9, 11 and has a plurality of annularly extending around the insulator longitudinal axis 13 permeabilar ⁇ term slats 17.
