Problems solved by technology

[0016] However, this installation also has some disadvantages
[0017] In fact, the cooling is not sufficient since the cooling fluid is sprayed by the injector and has to enter the pipe away from this injector

Embodiment Construction

[0028] With reference to the drawings, these drawings show the electrical connections of a sealed motor generally designated 1.

[0029] The motor is a sealed generator, which includes a housing that defines a high-pressure cavity 20 and a low-pressure cavity 21 (there are one or two fans 22 between the two cavities).

[0030] The high-voltage cavity 20 accommodates a stator with stator windings and a rotor with rotor windings.

[0031] The low-voltage cavity 21 accommodates the electrical connection including the lead conductor 3 and the sleeve 4, and the electrical connector 5 is arranged between the lead conductor 3 and the sleeve 4.

[0032] Special reference Figure 4 (The simplest embodiment of the present invention is shown), the electrical connection includes a housing 2 (which may be integrally formed with the housing 2 or not), and the housing 2 contains a lead connection connected to the sleeve 4 through an electrical connector 5 Conductor 3.

[0033] Depending on the parti...

Abstract

The electrical connection (1) of a sealed electrical machine comprises a casing (2) containing lead conductors (3) each connected to a bushing (4) via an electrical connector (5). The casing (2) has at least an inlet (6) and an outlet (7) for a cooling fluid. The electrical connector (5) comprises at least a permeable element defining a chamber (10) such that during operation the cooling fluid, passing through the chamber (10) and the permeable element, cools the permeable element. The method also refers to a method for cooling an electrical connection.

Description

Technical field [0001] The invention relates to an electrical connection of a sealed motor and a cooling method for cooling the electrical connection of a sealed motor. [0002] In particular, the motor of the present invention refers to a generator, and the electrical connection connects the winding or phase of the generator with the outside (for example, a transformer or a wire). Background technique [0003] In the prior art, a generator is provided with a stator and a rotor connected to an electric motor (for example, a steam turbine or a gas turbine), so that the rotor rotates in the stator and generates electric energy. [0004] The stator is provided with an electric winding (collecting electric energy), and the electric winding is connected with a lead conductor combined with the bushing. [0005] Typically, bushings are connected to electrical users, transformers or wires. [0006] In high-power generators (such as 500MW or above), during operation, a large amount of heat will...
