摘要:
The electric machine has a stator with windings connected to phase connections. An insulating cap protects the reciprocally connected portions of the phase connections and windings. The insulating cap has a box-shaped body with an opening for the introduction of a winding within it. The body defines a seat housing the phase connection. The seat is formed in one piece with the body.

An apparatus (10) for supporting a winding (7) on a stator (1), in particular on a generator stator in a power station. The winding (7) has an end winding (9) which is supported axially on the core (2) of the stator (1) via winding supports (11) of the supporting apparatus (10). The winding supports (11) are supported on the end winding (9) via a stressing device (22), at right angles to an envelope surface (21). In order to improve the axial position between the winding support (11) and the end winding (9) during operation of the stator (1), a coupling device (23) is provided which allows relative movements between the end winding (9) and the winding support (11) in the circumferential direction and at right angles to the envelope surface (21), and prevents such relative movements in an envelope line direction (30).

A method for the production of a supporting basket (1) for an end winding of a stator winding of an electrical machine includes preassembling the supporting basket (1), mounting electrically insulated round connectors (6) on the supporting basket (1), immersing the supporting basket (1) with the mounted round connectors (6) in an impregnation agent bath (12), evacuating the impregnation agent bath (12), and removing the supporting basket (1) with the mounted round connectors (6) from the impregnation agent bath (12), and drying, curing, or both, the impregnation.

The electrical connection of a sealed electrical machine is provided and includes a casing containing lead conductors each connected to a bushing via an electrical connector. The casing has at least an inlet and an outlet for a cooling fluid. The electrical connector includes at least a permeable element defining a chamber such that during operation the cooling fluid, passing through the chamber and the permeable element, cools the permeable element. A method is also provided for cooling an electrical connection.

摘要:
A horizontal-axis electrical machine has an built-in stator concentrically surrounded by a number of parallel retaining rings that spaced apart from one another in the axial direction and are connected on their outer circumference on opposing sides in each case by means of retaining structures to a base frame which extends in the axial direction. A horizontally acting spring, which has the form of a perpendicular, longitudinal plate, is fixed on the one hand with its ends to the associated retaining ring, and is firmly connected on the other hand with its freely flexible central part to the base frame by means of connecting elements, being provided within each of the retaining structures. Improved oscillation isolation between the built-in stator and the base frame is achieved in such an electrical machine by vertically acting spring elements disposed between the ends of the spring and the associated retaining ring.
