Problems solved by technology

However, in offshore or similar environments, the life of the slip ring is easily affected by the humid and salt spray environment and is significantly reduced
[0003] In addition, in order to meet the requirements of environmental protection, the slip ring system used in the sea should have the function of collecting carbon powder, but the structure of the carbon powder collecting device in the prior art is complicated and cannot meet the requirements of flame retardancy

Embodiment Construction

[0032] It should be noted that components in the various figures may be shown exaggerated for the purpose of illustration and are not necessarily true to scale. In the various figures, identical or functionally identical components are assigned the same reference symbols.

[0033] In the present invention, unless otherwise specified, "arranged on", "arranged on" and "arranged on" do not exclude the presence of intermediates between the two. In addition, "arranged on or above" only means the relative positional relationship between two parts, and under certain circumstances, such as after the product direction is reversed, it can also be converted to "arranged under or below", and vice versa Of course.

[0034] In the present invention, each embodiment is only intended to illustrate the solutions of the present invention, and should not be construed as limiting.

[0035] In the present invention, unless otherwise specified, the quantifiers "a" and "an" do not exclude the scen...

Abstract

The invention relates to the technical field of doubly-fed generator slip ring systems, and provides a closed offshore doubly-fed generator slip ring cooling system and method. The system comprises aslip ringcomponent, aslip ring box, a filtering system, a raidator and a cooling fan, wherein the slip ring box is configured to contain the slip ring component and enable the slip ring component to be isolated from air in a cabin of the offshore doubly-fed generator, and the slip ring box is provided with a closed air path which is not communicated with the outside; the filtering system is arranged in the closed air path so as to carry out filtering and heat exchange cooling on air; the radiator is arranged at the position, behind the filtering system, in the closed air path so as to carry out heat exchange cooling on the filtered air; and the cooling fan is arranged in the closed air path to enable air to sequentially flow through the filtering system, the radiator and the slip ring component, and the air flows through the slip ring component to clean impurity particles generated by operation of the slip ring component.

Description

technical field [0001] The present invention generally relates to the technical field of double-fed generator slip ring systems. Specifically, the present invention relates to a slip ring cooling system and method for a closed offshore doubly-fed generator. Background technique [0002] For double-fed generators, the reliable operation of the slip ring system is directly related to the health of the slip ring, carbon brushes and the oxide film formed by the interaction between the two. In the prior art, the cooling of the slip ring system usually adopts a technical solution with a protection level of IP23 and no protection against the incoming and outgoing wind. However, in offshore or similar environments, the life of the slip ring is easily affected by the humid and salt spray environment and is significantly reduced. [0003] In addition, in order to meet the requirements of environmental protection, the slip ring system used in the sea should have the function of colle...
