Problems solved by technology

[0006] The main disadvantages of mineral particle-filled epoxy resin gas insulated switchgear insulators are the weight of the component (e.g. two or three people are required to carry the largest insulator, i.e. more than 30 kg), the limited mechanical properties of the material and the relative brittleness, resulting in mechanical mutation failure

Embodiment Construction

[0026] Fiber-reinforced polymers are a special type of material consisting of a polymer matrix material reinforced with inorganic or organic fibers. The reinforcing fibers are the main load carrier, while the matrix part just transfers the load from fiber to fiber. In this specification, the polymer matrix is ​​composed of a typical anhydride cured epoxy resin usually used in electrical insulators, while the kind of reinforcing fibers can be of different types as long as it includes good electrical insulating properties. In general, glass fibers are of course the most suitable fibers for this solid electrical insulation application, especially E-RC glass fibers. However, other inorganic fibers such as basalt and quartz fibers, and organic fibers such as liquid crystal polymer, aromatic polyamide and polyethylene (p-phenylene-2,6-benzobisoxazole) fibers may also be used. In addition, the polymer matrix can be reinforced in different ways. Fibers can be continuous, in the form...

Abstract

Solid insulator for gas-insulated encapsulated high voltage installations with an insulator body, which is supporting at least one central conductor that is provided for carrying high voltage and that is arranged in an outer enclosure.The insulator body comprises a fiber-reinforced polymer.

Description

technical field [0001] The invention relates to a solid insulator according to the preamble of the first claim and also to a method of manufacturing a solid insulator according to the preamble of the independent method claim. Background technique [0002] In pressurized gas-insulated switchgear stations, the solid insulating element is disc-shaped with some complex substructural features including a central metal insert. [0003] DE 33 11 218 A1 discloses a disc-shaped insulator for enclosing high-voltage installations. The insulator includes a cast electrode that is segmented and extends peripherally concentrically about the side of the disk. The casting electrode is connected to the contact electrode via contact strips; the contact electrode is mounted on a metallic mounting ring. In order to avoid damage to the disc-shaped insulator, the contact piece, or the cast electrode during shrinkage of the disc-shaped insulator after casting, or damage caused by thermal stress d...
