摘要:
The corona shielding system according to the invention is a corona shielding system for an electrical machine. The corona shielding system comprises a filler in a polymer matrix, the filler comprising particles that contain mica and that surround the mica and at least one ceramic metal oxide-containing layer. The electrical machine is in particular a high-voltage machine and comprises such a corona shielding system.

The invention relates to a corona shielding paper for use in a corona shielding system for an electric machine, e.g. a high-voltage machine. In the simplest case, the corona shielding paper is produced by compacting partial discharge-resistant, planar, conductive particles but can comprise both reinforcement fibers and a woven fabric.

The corona shielding system according to the invention is a corona shielding system for an electrical machine and comprises a polymer matrix and particles arranged therein. The particles have a mica-containing core and a metal oxide-containing layer arranged on the core, the surface of the particles being functionalized, in particular for bonding to the matrix. The electrical machine comprises such a corona shielding system.
摘要:
The invention relates to a corona shielding system for an electric machine, for example a high-voltage machine, such as a generator, for generating electrical energy, an electric motor or else other electric operating means having a relatively high rated voltage, such as transformers, bushings, cables, etc. The corona shielding system is characterized by a filler mixture in which both planar and spherical particles occur. Therefore, the electrical conductivity, which is good in the presence of only planar particles in two spatial directions but is very poor in the third, can be adjusted anisotropically in a targeted manner.
摘要:
The invention relates to a corona shielding system for an electrical machine, comprising an outer corona shielding and an overhang corona shielding, both the outer corona shielding and the overhang corona shielding having the same corona shielding material which has a non-linear field strength-dependent electrical resistance. The electrical machine comprises such a corona shielding system.
