Detailed description of the invention
It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only the embodiments of the present invention,
For those of ordinary skill in the art, without creative efforts, it can also be obtained according to the following drawings
Other attached drawings.
Fig. 1 is the structural decomposition diagram of the sealing structure of the utility model substation arrester.
Specific embodiment
Below with reference to the attached drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear
Chu is fully described by.
The utility model substation has sealing structure 2 as shown in Figure 1 with arrester, is set to 1 top of arrestor porcelain bushing,
Between arrestor porcelain bushing 1 and arrester outer cover (not shown), including the multilayer opening 21 extended to form by arrestor porcelain bushing 1
And corresponding multiple sealing rings 22 and multilayer inner cover 23.In the present embodiment, with three layers of 21, three sealing ring 22 of opening and
For three layers of inner cover 23, but the utility model is without being limited thereto, while it is understood that the multiple sealing ring 22 uses difference
Material, thus a possibility that utmostly reducing these sealing rings while failing.
Wherein, multilayer opening 21 communicates with each other, and size successively increases from bottom to top, forms back taper.Each layer opening 21
Bottom, the junction with 1 top of adjacent apertures 21 or insulator, is formed with table top 210.The size of multiple sealing rings 22 is respectively with three
The dimensional fits of respective layer opening 21 in layer opening 21 allow it to just be set on the table top 210 of respective layer opening 21,
Sealing cooperation is formed with respective layer opening 21.In multilayer inner cover 23 size of each layer inner cover 23 respectively with respective layer opening 21 ruler
Very little cooperation allows it to just be placed in respective layer opening 21, compresses the sealing ring 22 being located on table top 210.
In the present embodiment, multilayer opening 21 is made with arrestor porcelain bushing 1 of identical material, but not limited to this, and
Preferably, multilayer opening 21 is integrally formed with arrestor porcelain bushing 1, so as to production.
Multiple sealing rings 22 can be used identical or different durable material and be made.Preferably, multiple sealing rings 22 use
Different materials are made, and to reduce the probability of itself while failure, improve the sealing performance of arrester, and extend arrester uses the longevity
Life.
Multilayer inner cover 23 is conductor, is made of an electrically conducting material, and in the present embodiment, which is integrally formed,
And size successively increases from bottom to top, forms back taper, each layer inner cover 23 compresses the sealing ring 22 at respective layer opening 21 respectively,
So sealing performance of enhancing arrester, it is also easy to produce.In addition to this, three layers of inner cover 23 can also three independent inner covers realities
It is existing, it is sequentially stacked, compresses the sealing ring 22 at respective layer opening 21 respectively.
When the sealing structure 2 of the utility model is assembled in substation's arrester, successively by multiple sealing rings 22 first
It is placed on the table top 210 of corresponding multilayer opening 21；Multilayer inner cover 23 is put into multilayer opening 21 again, each layer inner cover 23 is pressed
Sealing ring 22 at tight respective layer opening 21；The spring of arrester is placed in the top of top layer's inner cover 23 later, will be taken shelter from the thunder
The outer cover assembling of device thereon, compresses the insulator 1 of the outer cover and arrester and is bolted.
In this way, the utility model is able to provide a kind of sealing structure applied to substation's arrester, by multilayer
Opening, multiple sealing rings and multilayer inner cover realize the sealing of substation's arrester, seal with the prior art only with single layer
Circle, which is sealed, to be compared, and the sealing performance of arrester is not only increased, additionally it is possible to be kept preferable sealing effect for a long time, is suitable for length
Time uses, and then improves the operational reliability of arrester.
The above is only the preferred embodiment of the present invention, cannot limit the right of the utility model with this certainly
Range, therefore according to equivalent variations made by the utility model, it still falls within the scope of the utility model.
