| 摘要 |
The invention relates to a DC voltage high-voltage insulator (100) for insulating a conductor (200) applied with DC voltage, a high-voltage system for direct current with a DC voltage high-voltage insulator (100), and the use of a DC voltage high-voltage insulator (100) in a high-voltage system for direct current with an inner conductor (200) applied with DC voltage. The DC voltage high-voltage insulator (100) has a base body (50) made from insulating material and running about an insulator axis (A), at least one outer electrode (10a, 10b) running within the base body (50), preferably surrounding the insulator axis (A), and at least one inner electrode (20) running within the base body, preferably surrounding the insulator axis (A), wherein the outer electrode (10a, 10b) is arranged in the area of the outer periphery of the base body, wherein the inner electrode (20) is arranged in the area of the inner periphery of the base body, wherein in the axial cross section, the ratio of the average total width (wo) of the outer electrode (10a, 10b) to the average total width (wi) of the inner electrode (20) is at least 0.6, preferably at least 0.8, particularly preferably at least 1.0. |
