FIELD: electricity.SUBSTANCE: invention relates to energy transmission, for example, at a floating production, storage and offloading platform changing the orientation or at a wind turbine. Invention relates to electrical engineering. Energy transmission system of great power at an installation comprising the first part (1, 11) and the second parts (2,12), which rotate in respect to each other. A rotary three-phase transformer has primary (U1, V1, W1) and secondary windings (U2, V2, W2). The primary (U1, V1, W1) or secondary windings (U2, V2, W2) are mounted on the first part. The remaining windings are mounted on the second part: primary (U1, V1, W1) or secondary windings (U2, V2, W2). The primary (U1, V1, W1) and secondary windings (U2, V2, W2) are located one opposite the other. An air gap is provided between the primary (U1, V1, W1) and secondary windings (U2, V2, W2) and the respective transformer core parts. The first and the second transformer parts comprise at least one removable section (14a) including transformer legs with respective windings.EFFECT: simplification of operation and smaller dimensions.10 cl, 11 dwg |
