AI Technical Summary

Problems solved by technology

It has the disadvantage that the fabric does not contribute to the electrical strength of the insulation, so the volume fraction of the fabric in the insulation is limited, since the electrical strength is otherwise significantly limited
Thermal conductivities significantly greater than 0.5W / mK cannot be achieved with this solution

Embodiment Construction

[0050] Figure 1 shows an example of a conventional main insulation. The conventional main insulation 7 is arranged between the inner electrode 9 and the outer electrode 11. The main insulation 7 is made of multilayer Al on glass fabric / plastic 2 O 3 / Made of plastic. Reference numeral 7a indicates Al 2 O 3 / Plastic layer, and reference numeral 7b indicates a glass fabric / plastic layer, on which layer 7a is applied accordingly. In the cross-sectional view according to Fig. 1, a plurality of layers 7a and 7b are used to produce the main insulation 7 obtained from the winding of the layers 7a and 7b. The fabric / plastic intermediate layer 7b is located between the actual electrical insulator layers 7a, which prevents the increase in the total thermal conductivity of the main insulation. The reason is the series connection of thermal resistance, which means that the total thermal conductivity of the main insulation is determined by the maximum thermal resistance located in the ser...

Abstract

The invention relates to an insulating tape (1) in the form of a particle composite for an electrical insulating tape, use thereof as insulation, the insulation and the production of the insulating tape (1), wherein electrically insulating, platelet-shaped particles are connected by means of an electrically insulating binder to an electrical insulating material in the form of an at least partially porous insulating tape (1). The invention is characterized in that the insulating tape (1) is windable on a conductor structure (9, 11) when wound under exerted tension force, namely without addition of a materially additionally impeding heat flow. A thermal conductivity which is greater relative to the prior art is advantageous for preventing heat accumulation and total failures, in particular of main insulation (7).

Description

Technical field [0001] The invention relates to an insulating tape according to the preamble of the independent claim, its application as electrical insulation for electrical machines, in particular rotating electrical machines, electrical insulation and a method of manufacturing the insulating tape. Background technique [0002] In rotating electrical machines, such as electric motors or generators, the reliability of the insulation system has a decisive responsibility for its operational safety. The task of the insulation system is to permanently insulate electrical conductors, specifically wires, coils, rods, sub-conductors, etc., relative to each other and relative to the stator lamination stack or the surroundings. In high-voltage insulation, a distinction is made between the insulation between sub-conductors called sub-conductor insulation, the insulation between conductors or windings called conductor or winding insulation, and the conductor called main insulation and the ...
