Abstract
The utility model discloses an insulation sleeve pipe comprising a hollow pipe body (10) and a metal coating (20) arranged on the outer surface of the pipe body; a first net ring (30) is arranged in a position, corresponding to an end portion of the metal coating (20), in the pipe body (10); the first net ring (30) is connected with the metal coating (20). The insulation sleeve pipe can improve partial discharge close to the upper end portion of the metal coating.
Description
Technical field
The utility model relates to high-tension apparatus, the insulating sleeve that is specifically related to use in high voltage switchgear.
Background technology
Existing insulating sleeve as shown in Figure 1, in body 1 inner hollow of being made by insulating material, in order to wear metallic conductor 4.In the outside of body 1, be provided with the coat of metal 2.Below body 1 inside, be provided with wire netting circle 3, in order to charged demonstration.
Summary of the invention
The purpose of this utility model is at least to improve near the partial discharge problem in upper end of the coat of metal.
According to the utility model, an insulating sleeve, comprises the body of hollow and is located at the coat of metal on described outer surface of tube body, wherein, in the inside of described body, the position corresponding with the end of the described coat of metal, be provided with the first net circle, described the first net circle is connected with the described coat of metal.
Wherein, on the outer surface of the body enclosing at described the first net, be provided with at least one pin, described pin extension passes described body and is connected with the described coat of metal.
The upper lower edge of the body wherein, enclosing at described the first net is formed with respectively the flange with curved surfaces.
Positive progressive effect of the present utility model is: near the partial discharge of upper end that can improve the coat of metal.
Accompanying drawing explanation
Fig. 1 is the cross-sectional schematic of existing insulating sleeve.
The cross-sectional schematic of Fig. 2 the utility model one embodiment.
Fig. 3 is the schematic diagram of the first wire netting circle shown in Fig. 2.
Embodiment
Below in conjunction with preferred embodiment of the present utility model, the utility model is described.Many concrete details in description below, have been enumerated.Yet, it will be appreciated by those skilled in the art that the utility model also can not adopt some or all in these details and realize.In some situations, known technology is not described to avoid unnecessary obscuring.
As shown in Figure 2, according to an embodiment of the present utility model, insulating sleeve 100 has body 10, and described body 10 inner hollow, hold metallic conductor in order to wear.Described body 10 is made by insulating material, for example, includes but not limited to epoxy resin etc.Generally, the outside of body 10 is also provided with umbrella portion or fluxion structure, to increase the creepage distance of outer surface of tube body.On the outer surface of body 10, be also provided with the coat of metal, its effect is to control insulating sleeve Electric Field Distribution around.
In the example shown in Fig. 2, the coat of metal 20 is positioned at the part on body 10 outer walls.It is pointed out that Fig. 2 just illustrates an example, its effect is to illustrate the utility model, rather than restriction, and those skilled in the art can understand, and according to concrete applied environment, the coat of metal can change in the position of tube wall stopwatch face.
Near the end of the coat of metal 20, likely there is partial discharge.For this reason, in the inside of body 10, the position corresponding with the end of the coat of metal 20, the first net circle 30 is set.Described net circle 30 can make by metal mesh material is crooked.Obviously, the manufacture method that other can be known to those skilled in the art in addition, does not repeat them here.
Fig. 3 illustrates the axonometric drawing of described the first net circle.Net circle 30 comprises body 32 and is fixed on the pin 34 of this external surface.Wherein, the length of described pin is configured to stretch out the body 10 of described insulating sleeve, and is connected with the described coat of metal 20.
In the example shown in Fig. 3, described the first net circle 30 is provided with two pins 34.Yet those skilled in the art can and determine the quantity of set pin 34 according to the description of this specification according to the requirement of concrete application.Such as, pin still less can be set, as 1 pin, or more sell, as 3,4 or more.
By this way, between the coat of metal 20 and the first net circle 30, form conductive connection, and ground connection together, thereby the partial discharge of the coat of metal 20 ends improved.The position of the net of first shown in Fig. 2 circle 30 and the coat of metal 20 is exemplary, rather than for restriction of the present utility model.It is evident that, those skilled in the art can, according to concrete product configurations, according to description of the invention, arrange the described coat of metal and the first described net circle in the position of actual needs.
The upper lower limb of described the first net circle 30 is formed with the flange 36 with curved surfaces, thereby is reduced in the possibility of net circle edge partial discharge.
Similarly to the prior art, in the example shown in Fig. 2, in the bottom of body 10, be also provided with the second net circle 40, it is for charged demonstration.
In conjunction with embodiment, the utility model be have been described in detail above.Yet, it will be appreciated by those skilled in the art that and in scope of the present utility model, also have some modifications and equivalent way.
For example, although connect first net circle and the coat of metal with pin in the utility model, yet also can adopt other modes known to those skilled in the art.
Therefore, claim of the present utility model should be interpreted as comprising all such modifications and equivalent way.
