Description
Technical field
Sealing structure technical field is the utility model is related to, is used for outdoor electric current and voltage transformer more particularly to one kind
On novel sealing structure.
Background technology
Apply at present electric field electric current and voltage transformer mainly using oil-insulation and sulfur hexafluoride gas-insulating as
Main, the sealing structure between different components mainly based on the quiet honey envelope using rubber seal, as shown in Figure 3 and Figure 4, is put into practice
Proving, this structure can ensure effective sealing of mutual inductor in most occasions, but outdoors under some adverse circumstances, this
Kind structure longtime running occurs that airtight quality declines and the situation of sealing medium leakage, the operation to meeting sensor bring safe hidden
Suffer from.
Utility model content
The utility model is mainly solving the technical problems that provide a kind of new on outdoor electric current and voltage transformer
Type sealing structure, can effectively seal the dielectric inside outdoor electric current and voltage transformer and to outside
The factor such as rainwater isolated, protect rubber seal from the erosion of the factors such as rainwater.
In order to solve the above technical problems, the technical solution that the utility model uses is：One kind is provided and is used for electrical outdoor
Novel sealing structure on stream and voltage transformer, this kind are used for the novel sealing structure on outdoor electric current and electric piezoelectric transformer
Including base, shield, fastening bolt and rubber seal, the base upper end is provided with shield, and base is equipped with installation through-hole,
Shield bottom corresponding position is provided with mounting hole, and fastening bolt is housed in installation through-hole, and fastening bolt is screwed into mounting hole,
Base and shield are fixed by fastening bolt, and base upper surface is equipped with annular groove, and rubber seal, rubber are housed in annular groove
Glue sealing ring both ends of the surface are close to base and shield, and base is additionally provided with annular seal groove, and annular seal groove is located at annular groove outer ring,
Flat sealant is housed in annular seal groove.
Compared with prior art, the beneficial effects of the utility model are：Increase a special use in existing sealing structure
To fill the small-sized sealing groove of the waterproof materials such as flat sealant, design is simple, can be to outdoor electric current and voltage transformer
Internal dielectric is effectively sealed, and the factors such as the rainwater of outside can be isolated, protect rubber seal from
The erosion of the factors such as rainwater.
