Abstract
The utility model relates to a single-side compound shield cover which mainly plays a role of shielding a power distribution system of an electric apparatus. The double-side compound shield cover comprises a shield cover body (1); the shield cover body (1) adopts an inverted cup-shaped structure and is made of copper; and the outer surface of the shield cover body (1) is coated with a tin coating (2). The outer surface of the shield cover body is coated with tin coating, so that the utility model can prevent the copper shield cover body from being oxidized, and greatly prolong the service life of the shield cover.
Description
(1) technical field
The utility model relates to a kind of radome.Be mainly used in the hydroelectric station, nuclear power station electrical equipment distribution system plays the screen effect.
(2) background technology
Before the utility model is made, be used for radome that various electrical equipment distribution systems play the screen effect in the past and rise to stretch by layer of copper mostly and form inverted cup-like structure.Cause oxidation after this radome uses for a long time easily, greatly reduce the useful life of radome like this.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of single face composite shielding cover that is difficult for oxidation is provided.
The purpose of this utility model is achieved in that a kind of single face composite shielding cover, comprises the radome body, and described radome body is made of copper inverted cup-like structure, is coated with the tin layer at the outer surface of described radome body.
The utility model plates the tin layer by the outer surface at the radome body, can prevent the oxidation of copper radome body like this, to prolong the useful life of radome greatly.
(4) description of drawings
Fig. 1 is the outside drawing of the utility model single face composite shielding cover.
Fig. 2 is the A-A cut-away view of Fig. 1.
Among the figure: radome body 1, tin layer 2.
(5) embodiment
Referring to Fig. 1, the single face composite shielding cover that the utility model relates to comprises radome body 1, and described radome body 1 is made of copper inverted cup-like structure, is coated with tin layer 2 at the outer surface of described radome body 1.
Claims (1)
1, a kind of single face composite shielding cover comprises radome body (1), and described radome body (1) is made of copper inverted cup-like structure, it is characterized in that: the outer surface at described radome body (1) is coated with tin layer (2).
