Description
Technical field:
The utility model relates to a kind of plug hair style bushings shell for transformer of heat-resistant fireproof.
Background technique:
Conventional 40.5kV and following voltage class transformer are epoxy resin pouring casing with plug-in casing；Structure is
Intermediate conducting rod is equipped with earthing, is insulated between the two with poured with epoxy resin, since size is small, and is epoxy pouring type, nothing
Method realizes that increasing capacitance plate among earthing and intermediate conducting rod carrys out uniform electric field.
The casting insulated inside of pure epoxy resin is also easy to produce micro-crack and brittleness height, poor fire；The electric field collection at earthing
In, casing shelf depreciation probability is high；Easy firing is burst when breaking down.
Summary of the invention:
The purpose of the utility model is to provide a kind of low partial discharge, flame retardant type, high mechanical strength 40.5kV and following voltage
The plug hair style bushing shell for transformer of the heat-resistant fireproof of grade.
Technical solution used by the utility model has: a kind of plug hair style bushing shell for transformer of heat-resistant fireproof, including
Intermediate conducting rod, is arranged insulator on the outer wall of intermediate conducting rod, and the insulator is layer-by-layer by glass fibre yarn epoxy resin-impregnated
It is entwined, and arranges several capacitance plates between glass fibre yarn epoxy resin-impregnated and form multilayer screen, in outermost capacitor
Connection ground connection deriving structure on screen forms coaxial cylindrical electric field, insulator winding between intermediate conducting rod and each layer capacitance screen
Curing molding afterwards.
Further, the capacitance plate arranges 2-10 layers.
Further, the capacitance plate uses metal or semiconductive composite material.
The utility model has the following beneficial effects:
Coaxial cylindrical electric field structure in the utility model reduces the shelf depreciation of casing conducive to electric fields uniform distribution
Amount；With insulator made of glass fiber yarn epoxy resin-impregnated have high flame retardant, dense internal organization, high mechanical strength
Advantage.Casting mold is not needed in the fabrication process, it is with short production cycle convenient for batch production.
Detailed description of the invention:
Fig. 1 is the utility model structure diagram.
Conducting rod among 1- in figure；2- capacitance plate；3- insulator；4- is grounded deriving structure.
Specific embodiment:
The utility model will be further described below with reference to the accompanying drawings.
Such as Fig. 1, a kind of plug hair style bushing shell for transformer of heat-resistant fireproof of the utility model, including intermediate conducting rod 1, In
Insulator 3 is set on the outer wall of intermediate conducting rod 1, and insulator 3 is successively entwined by glass fibre yarn epoxy resin-impregnated, is wrapped over
Cheng Zhong arranges several capacitance plates 2 between glass fibre yarn epoxy resin-impregnated and forms multilayer screen, on outermost capacitance plate 2
Connection ground connection deriving structure 4, forms coaxial cylindrical electric field between intermediate conducting rod 1 and each layer capacitance screen 2, insulator 3 is wound
Curing molding afterwards.
Capacitance plate 2 arranges 2-10 layers, and capacitance plate 2 uses metal or semiconductive composite material.
Use glass fibre yarn epoxy resin-impregnated wound and solidified for insulation, since glass fibre yarn epoxy resin-impregnated is successively to twine
Around, thus can in glass fibre yarn interlayer according to design arrangement multilayer screen (2-10 layers) come uniform electric field, outmost turns are ground connection
Screen.
Paved multi-layer capacity screen 2 during the winding process, capacitance plate 2 use metal or semiconductive composite material；Outermost layer screen
It covers and is connect with ground connection deriving structure 4.Coaxial cylindrical electric field is formed between conducting rod and each layer capacitance screen, through drying after winding
Curing molding.
Coaxial cylindrical electric field structure in the utility model reduces the shelf depreciation of casing conducive to electric fields uniform distribution
Amount；With insulator made of glass fiber yarn epoxy resin-impregnated have high flame retardant, dense internal organization, high mechanical strength
Advantage.Casting mold is not needed in the fabrication process, it is with short production cycle convenient for batch production.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
It for art personnel, can also make several improvements without departing from the principle of this utility model, these improvement also should be regarded as
The protection scope of the utility model.
