Description
Technical field
The present invention relates to bushing shell for transformer, and in particular to a kind of oil immersed type capacitance graded bushing.
Background technology
Bushing shell for transformer service condition is extremely harsh, is subject to voltage, electric current, pulling force, vibrations, wind-force, air dirty during operation
Etc. many combined influences, once producing failure, easily cause fault spread, loss is serious；Therefore, sleeve pipe is also each main frame
The accessory paid close attention to the most in accessory, existing oil immersed type capacitance graded bushing, conducting rod and insulator are to the Electric Field Distribution between flange
Very uneven, structure design is unreasonable, causes the anti-compressive resistance of complete equipment not enough, and resistance to shorting surge voltage is indifferent, difficult
To ensure the reliability of oil immersed type capacitance graded bushing；Additionally, after sleeve pipe is installed, by pulling force, the active force such as vibrations, and flange connections
Capacitor core surface stress it is maximum, be easily damaged capacitor core, so as to influence the safe operation of product.
The content of the invention
It is an object of the invention to provide a kind of oil immersed type electric capacity that rational in infrastructure, Electric Field Distribution is uniform, anti-compressive resistance is high
Sleeve pipe.
The technical scheme is that：A kind of oil immersed type capacitance graded bushing, including connector lug, the first grading shield, trim ring, bolt
And spring, oil conservater, upper section insulator, the first seal washer, measurement terminal, the second seal washer, lower section insulator, second presses
Cover, suspension ring, bleeder plug, capacitor core, first grading shield is provided with the cylindrical shape of opening for two ends, along equal at the opening
The axial direction of cover is pressed to be provided with flange.
By chamfered at described opening and flange, the chamfering is fillet.
The radius of the opening is 60-80mm.
The external diameter of the grading shield is 120-160mm.
The height of the flange is 20-50mm.
The beneficial effects of the present invention are：
The oil immersed type capacitance graded bushing is set to the shape with flange by by grading shield, makes that its Electric Field Distribution is more uniform, carries
Anti- compressive resistance high.
Brief description of the drawings
Fig. 1 is the front view of oil immersed type capacitance graded bushing of the present invention.
Fig. 2 is the front view of oil immersed type capacitance graded bushing grading shield of the present invention.
Fig. 3 is the top view of oil immersed type capacitance graded bushing grading shield of the present invention.
Wherein：1st, connector lug 2, the first grading shield 21, opening 22, flange 3, trim ring 4, bolt and spring
5th, oil conservater 6, upper section insulator 7, the first seal washer 8, measurement terminal 9, the second seal washer 10, second are pressed
Cover 11, suspension ring 13, bleeder plug 14, capacitor core.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and detailed description.
A kind of oil immersed type capacitance graded bushing, including connector lug 1 as shown in Figure 1, Figure 2, Figure 3 shows, connector lug 1 draws Transformer Winding
Line is connected to external power circuit use, the first grading shield 2, trim ring 3, bolt and spring 4, oil conservater 5, and oil conservater 5 is in order to compensate
Inside pipe casing transformer oil varies with temperature the Volume Changes for causing, and oil level indicator can also be set on oil conservater, is used to
Sleeve pipe internal transformer oil level is indicated, there is brute spring in oil conservater, be used to for sleeve pipe to be linked to be an entirety, oil leak does not occur,
Upper section insulator 6, the first seal washer 7, measurement terminal 8, the second seal washer 9 is lower to save insulator 10, and the design of same insulator is
In order to ensure still there are enough creep age distances in filthy and condition setting of casing of drenching with rain；Second grading shield 11 is it can also be provided that press
Ring, to reduce the volume of the sleeve pipe, can be configured according to actual needs, and suspension ring 12 are convenient to carry out lifting movement to sleeve pipe, hangs
Ring 12 is shaped as circle, it is also possible to be set to ellipse, rectangle etc.；Bleeder plug 13, capacitor core 14 is set to tubular, fuse
Concrete structure it is relevant with amount of capacity, voltage levels, operating temperature range, frequency low factor high, first grading shield 2
The cylindrical shape of opening 21 is provided with for two ends, the axial direction of grading shield 2 flange 22 is provided with the opening 21 why
Cylindrical shape is set to, its shape can inherently be such that its Electric Field Distribution uniformly acts on, then along pressing at opening 21
The axial direction of cover 2 is provided with flange 22, further increases Electric Field Distribution uniform properties, additionally, by the described He of opening 21
By chamfered at flange 22, the chamfering is fillet, prevents wedge angle, and shelf depreciation occurs, and can also make its electricity
Field distribution is uniform, improve anti-compressive resistance.
The radius of the opening 21 is 60-80mm, and the external diameter of the grading shield 2 is 120-160mm, the height of the flange 22
It is 20-50mm to spend.
The present invention has advantages below：
One is rational in infrastructure, and fit dimension is reduced, cost-effective；
Two be on the oil immersed type capacitance graded bushing for make transformer save position Electric Field Distribution it is more uniform；
Three is its anti-compressive resistance is reached standard requirement.
One embodiment of the present of invention has been described in detail above, but the content is only preferable implementation of the invention
Example, it is impossible to be considered as limiting practical range of the invention.All impartial changes made according to the present patent application scope and improvement
Deng all should still belong within patent covering scope of the invention.
