Description
Technical field
The utility model belongs to water seepage-proof tech field between unlike material.Especially novel rectifying transformer, electric furnace become
Depressor secondary power supply exports conducting rod prevents transformation between conducting rod and combined type insulating sleeve through the output of combined type insulating sleeve
A kind of device of device oil seepage.
Background technology
Novel rectifying transformer, furnace transformer secondary power supply output be will export conducting rod penetrate it is close with transformer
In the combined type insulating sleeve of connection, then it will be used and be covered after clearance seal between conducting rod and combined type insulating sleeve with epoxy resin
Pipe fixing piece is fixed on the transformer.Due to using epoxy between combined type insulating sleeve and secondary power supply output conducting rod
Resin seal mode, there is combined type insulating sleeves and transformer secondary power supply to export conducting rod（Copper）Coefficient of thermal expansion not
Together, it is easy to happen defect of the transformer oil by casing and conducting rod gap leakage when operation, influences transformer normal operation, oozes
Transformer may be caused out of service when leaking serious, heavy losses are caused to production system.
Utility model content
Conducting rod is exported in order to solve transformer secondary power supply in the prior art（Copper）Ring is used with combined type insulating sleeve
Oxygen resin seal mode is easy to happen transformer oil leakage, and leakage influences transformer normal operation, may cause to become when serious
Depressor is out of service, the problem of causing heavy losses to production system, and the utility model, which provides one kind, prevents transformer compound absolutely
A kind of transformer combined type insulating sleeve of oil seepage between edge casing and conducting rod.
The utility model is achieved through the following technical solutions.
A kind of transformer combined type insulating sleeve, by conducting rod（1）, epoxy resin layer（2）, connecting plate（4）And casing（3）
Composition, the conducting rod（1）Positioned at the center of described sleeve pipe, the epoxy resin layer（2）It is filled in the conducting rod（1）With institute
State casing（3）Between, annular groove is provided on the epoxy resin layer, the depth of the groove is more than the epoxy resin
Layer, a sealing rubber ring are located in the groove.
The sealing rubber ring internal diameter is less than conductive shank diameter, and it is flexible rubber seal cushion rubber.
The groove is located at the epoxy resin layer edge 20mm, and the wide 5mm of groove is deep under conducting rod
1mm。
Leakage-repairing glue is filled at the sealing rubber ring, leakage-repairing glue periphery is concordant with the epoxy resin layer, described sleeve pipe two
End is cast with epoxy resin 6.
4 surrounding of the connecting plate is provided with screw hole 5, for installing on the transformer casing.
The utility model uses two-in-one transformer oil sealing means, one to install sealing rubber ring additional and effectively solve combined type
Insulating sleeve exports conducting rod with transformer secondary power supply（Copper）Coefficient of thermal expansion it is different or epoxy resin aging causes transformation
Device oil seepage；The second is at transformer leakage-repairing glue filling with sealant circle installation, to reinforce sealing, casing and conducting rod are eliminated
Between epoxy resin aging, fall off caused by transformer oil leak.
Compared with prior art, the utility model uses the technology that sealing rubber ring is combined with transformer leakage-repairing glue, eliminates
Bushing shell for transformer leakage of oil caused by material difference and material ageing.With epoxy resin sealing resin it is easy to aging, fall off and make
Transformer caused by bushing shell for transformer leakage of oil is stopped transport, and the guarantee bushing shell for transformer that the utility model can be relatively reliable will not leak
Oil ensures transformer stable operation.
Description of the drawings
Fig. 1 -- the cross-sectional view of the structure of the utility model casing.
The epoxy of 1-conducting rod 2-epoxy resin layer, 3-casing, 4-connecting plate, 5-screw hole 6-- cast
Resin.
Specific implementation mode
The utility model is described in detail with reference to the accompanying drawings and detailed description.
After bushing shell for transformer occurs that transformer is deactivated disintegration in the case that transformer oil leakage influences safety in production,
The copper conducting rod that leakage of oil occurs is taken out from combined type insulating sleeve, in copper conducting rod tail portion, epoxy resin section start is upward
Epoxy resin thereon is gone out the annular groove that a width 5mm is deep to 1mm under copper conducting rod by 20mm with lathe car, and one is installed additional in groove
Internal diameter is less than conductive shank diameter rubber seal cushion rubber with strong elasticity, then uses at transformer leakage-repairing glue filling with sealant circle installation,
To make when filling it is more slightly higher at sealing rubber ring installation, it is more at removal cushion rubber installation after transformer leakage-repairing glue in place's to be sealed solidification
Remaining filler and by surrounding arrange it is smooth after, after conducting rod is fitted into combined type insulating sleeve again with resin-cast seal it is compound
Casing and the conductive body of rod are packed into transformer secondary power supply outlet side after resin drying, use connector by formula insulating sleeve both ends
Casing it is fixed with transformer body with the conductive body of rod after connect respective bus bars, attachment, after transformer assembling pass the test
Transformer can be put into operation.
Fluid sealant is utilized by the way of rubber seal cushion rubber with strong elasticity and the filling of transformer leakage-repairing glue in the present embodiment
The elasticity that enclosing has closely is connect with conducting rod, it is therefore prevented that and transformer oil leaks from conducting rod and aging epoxy resin gap,
Blocking, the effect of hermetically-sealed- transformer oil are played, copper conducting rod and transformation caused by epoxy resin coefficient of thermal expansion difference have been prevented
Device oil seepage；Have using transformer leakage-repairing glue and compresses sealing rubber ring and utilization with preferable Nian Jie play of combined type insulating sleeve
The toughness that transformer leakage-repairing glue has has blocked transformer oil oily from the conductive body of rod and combined type insulating sleeve gap leakage, from
And transformer secondary power supply outlet side is made to export conducting rod using combined type insulating sleeve and transformer secondary power supply（Copper）Between
It is easy to happen transformer oil leakage using epoxy resin sealing means, transformer normal operation is influenced and transformer may be caused
Problem out of service is addressed.
Above-described is only the preferred embodiment of the utility model, does not limit to utility model.It should be understood that for this
For the those of ordinary skill in field, under technical inspiration provided by the utility model, other equivalent improvement can also be made,
The purpose of this utility model may be implemented, be regarded as the scope of protection of the utility model.
