| 摘要 |
The present invention relates to a transformer (2) containing an electrical active part (4) arranged in an insulating space (14) and comprising a primary winding (8), secondary winding (6) and a magnetic core (10), said windings (6, 8) being wound around the magnetic core (10) and being radially spaced apart from each other by a winding space (12) comprising an insulation fluid (16; 16a). The transformer (2) further comprises a block (18) defining a compartment (20) closed and separated from the remaining insulating space (22), said closed compartment (20) being at least partially arranged within the winding space (12). The invention is characterized in that the closed compartment (20) comprises an insulation fluid (16a) which is different from the insulation fluid (16b) comprised in the remaining insulating space (22) of the transformer (2), the insulation fluid (16a) comprised in the closed compartment (20) having a higher dielectric breakdown field strength than the insulation fluid (16b) comprised in the remaining insulating space (22). |
