Description
Technical field
The utility model is related to power equipment accessories technical fields, particularly relate to a kind of novel flange type low-tension transformer set
Pipe.
Background technology
Currently, all selecting substantially for the casing high pressure that side is installed in domestic distribution transforming Transformer-Manufacturing Trade is flanged, and
Low pressure composite bushing still selects traditional porcelain bushing shell.However when traditional porcelain bushing shell side installation, due to conducting rod and connector lug to
Under gravity can focus on the tail portion covered in casing, and then seal gasket unbalance stress can be led to, for a long time, with rubber cushion bullet
The decline of property, it is possible that the problem of oil leak.
Utility model content
The utility model proposes a kind of novel flange type prevention low-voltage transformer bushings, solve mentioned above in the background art
Problem.
What the technical solution of the utility model was realized in：
A kind of novel flange type prevention low-voltage transformer bushing, including connecting terminal and conducting rod, conducting rod is from top to bottom successively
It is provided with copper nut, gland, middle set, transformer box cover and traps, glue bead, middle set and transformation are provided between gland and middle set
It is provided with seal gasket between device case lid；In put on and be provided at least two aluminium flanges, have mounting hole on aluminium flange；Transformer tank
Lid is connected by bolt through mounting hole and iron flange screw thread with a threaded iron flange, middle set is welded on mounting hole corresponding position
It connects.
As further technical solution, in put on the aluminium flange of setting be specially four.
As further technical solution, middle set is Nian Jie with aluminium flange.
The beneficial effects of the utility model are：
The utility model proposes novel flange type prevention low-voltage transformer bushing, knot is connect with transformer box cover by centered cover
The improvement of structure makes the gravity of conducting rod and connector lug also just be shared onto fastening bolt, and the uniform force of seal gasket is not
Become, increase leakproofness, avoid the possibility of oil leak, and seal gasket is placed in flange groove, reduction is contacted with the external world, by
The influence of environment reduces, and increases service life；In addition the casing that utility model proposes is identical as traditional sleeve structure member, more
Number component is general, and user is facilitated to replace, and has good inheritance.
Description of the drawings
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
FIG. 1 is a schematic structural view of the utility model.
In figure：1, connecting terminal；2, conducting rod；3, copper nut；4, gland；5, middle set；6, transformer box cover；7, it traps；
8, glue bead；9, seal gasket；10, aluminium flange；11, bolt.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
The every other embodiment obtained, shall fall within the protection scope of the present invention.
As shown in Figure 1, the utility model proposes a kind of novel flange type prevention low-voltage transformer bushing, including connecting terminal 1
With conducting rod 2, conducting rod 2 is from top to bottom disposed with copper nut 3, gland 4, middle set 5, transformer box cover 6 and traps 7,
It is provided with glue bead 8 between gland 4 and middle set 5, seal gasket 9 is provided between middle set 5 and transformer box cover 6；It is arranged on middle set 5
There are at least two aluminium flanges 10, has mounting hole on aluminium flange 10；On transformer box cover 6 on mounting hole corresponding position weld one
Threaded iron flange, middle set 5 are threadedly coupled through mounting hole with iron flange by bolt 11.
As further technical solution, the aluminium flange 10 being arranged on middle set 5 is specially two.
As further technical solution, middle set 5 is Nian Jie with aluminium flange 10.
Through measuring and calculating, the novel flange type prevention low-voltage transformer bushing specification now used is middle to cover the aluminium flange 10 being arranged on 5 preferably
It is two, can both the gravity of conducting rod 2 and connector lug was used to be shared to two 11 uniform forces of fastening bolt, and ensures to make
With the service life, and the use of connector can be reduced, it is cost-effective.
The beneficial effects of the utility model are：
The utility model proposes novel flange type prevention low-voltage transformer bushing, connect with transformer box cover 6 by centered cover 5
The improvement of structure makes the gravity of conducting rod 2 and connector lug also just be shared onto fastening bolt 11, the stress of seal gasket 9
It is uniformly constant, leakproofness is increased, avoids the possibility of oil leak, and seal gasket 9 is placed in flange groove, is contacted with the external world
It reduces, reduction protected from environmental increases service life；In addition the casing and traditional sleeve structure member that utility model proposes
Identical, most components are general, and user is facilitated to replace, and have good inheritance.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all in this practicality
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
