Embodiment
It is below in conjunction with the accompanying drawings and real in order to be more clearly understood that the above-mentioned purpose of the utility model, feature and advantage
Example is applied to be described further the utility model.It should be noted that in the case where there is no conflict, embodiments herein and reality
Applying the feature in example can be mutually combined.
Many details are elaborated in the following description in order to fully understand the utility model, still, this practicality
New to implement using different from other modes described here, therefore, the utility model is not limited to be described below
The limitation of the specific embodiment of specification.
Embodiment 1, as shown in Figure 1, the present embodiment provides a kind of oil immersion-type distribution transformer iron core fixture, with traditional
Fixture is the same, and the fixture that the present embodiment is provided also is composed of four parts, be respectively iron core side preceding upper clamping piece 1,
Preceding lower clamping piece 2 and the rear upper clamping piece 3 of iron core opposite side, rear lower clamping piece 4 are arranged on, the setting of four folders, constitutes in length
The fixture of cube shape, iron core are arranged in fixture, with traditional yi word pattern folder unlike, the present embodiment provide before on
Folder 1, preceding lower clamping piece 2, rear upper clamping piece 3 and the rear L-shaped setting of lower clamping piece 4, the setting of L-type effectively instead of traditional
Between preceding upper clamping piece 1 and rear upper clamping piece 3 drawing screw rod setting, using preceding upper clamping piece 1, preceding lower clamping piece 2, rear upper clamping piece 3 and
4 material of lower clamping piece is the setting of channel steel afterwards, and the preceding upper clamping piece 1 effectively improved is with rear upper clamping piece 3 and preceding lower clamping piece 2 with after
The bonding strength and anti-strike capability of lower clamping piece 4, make it after being collided, and can not influence iron core.It is preceding in order to clamp iron core
When in use, its short side can not touch what is be matched therewith for upper clamping piece 1, preceding lower clamping piece 2, rear upper clamping piece 3 and rear lower clamping piece 4
The long side of folder, therefore, between preceding upper clamping piece 1 and rear upper clamping piece 3 by bolt 5 fix form oblong-shaped, preceding lower clamping piece 2 with
Composition oblong-shaped is bolted between lower clamping piece 4 afterwards, in the present embodiment, the short side of folder is matched therewith long side
For spacing when specifically used, its spacing is no more than 25mm, in this way, it is possible to when colliding, avoids bolt 5 from rolling over
It is curved, and then ensure the safety of iron core.
Iron core is fixed in transformer shell body for convenience, is provided with the lower section of preceding lower clamping piece 2 and rear lower clamping piece 4
Iron core fixed seat 6, is both provided with fixed seat 7 at the top of iron core on preceding upper clamping piece 1 and rear upper clamping piece 3, is fixed with traditional iron core
Seat is four sections, unlike the every two sections structures for being arranged on preceding lower clamping piece 2 or rear lower clamping piece 4, the iron core that the present embodiment is provided
Fixed seat 6 is two iron core fixed seats 6 through preceding lower clamping piece 2 or rear lower clamping piece 4, and one is welded on preceding lower clamping piece, another
It is welded on rear lower clamping piece, two iron core fixed seats 6 are arranged in parallel, in preceding lower clamping piece 2 or the corresponding spiral shell of setting of rear lower clamping piece 4
Keyhole (not shown), in this way, the iron core fixed seat for being welded on preceding lower clamping piece 2 is bolted on rear lower clamping piece 4, together
Reason, is welded on same, such setting of the iron core fixed seat of rear lower clamping piece 4, is conducive to improve the intensity of a whole set of fixture.
It is smaller in view of the thickness of fixed seat 7 at the top of iron core, in the handling process, after colliding, it is easy to it bent,
During installation, it is also necessary to pull just, do not influence installation accuracy tightly, equally, also influence service life.In order to avoid the hair of problems
Raw, in the present embodiment, fixed seat 7 is detachably arranged at preceding upper clamping piece 1 and rear upper clamping piece 3, specifically, iron core at the top of iron core
The bolt hole that top fixed seat 7 includes fixed seat body 71 in T shape and is arranged on fixed seat body 71 (does not show in figure
Go out), bolt hole is arranged on T-shaped cross bar, that is, is arranged on the both sides of upright bar, is provided with preceding upper clamping piece 1 and rear upper clamping piece 3
Through hole (not shown) matched with fixed seat 7 at the top of iron core and the bolt 5 for fixed seat at the top of secured core, by
It is that channel steel is set in preceding upper clamping piece 1 and rear upper clamping piece 3, in this way, screw rod 5 is just arranged under preceding upper clamping piece 1 and rear upper clamping piece 3
On layer steel plate, it coordinates with bolt hole makes iron core top fixed seat 7 when not in use, and only fraction is exposed outside, in this way, just
The collision of transportational process is avoided, and then ensure that installation accuracy and service life.
In order to further improve the intensity of whole fixture, in the present embodiment, preceding upper clamping piece 1, preceding lower clamping piece 2, rear upper folder
The middle part of part 3 and rear lower clamping piece 4 is both provided with reinforcing rib 9, and reinforcing rib 9 is triangle muscle, it is provided with overall beneficial to raising
Intensity.
It is the same with traditional fixture, in this embodiment, preceding upper clamping piece 1 and preceding lower clamping piece 2 and rear upper clamping piece 3 and rear lower folder
By drawing screw rod 8 to fix come firm spacing between the two between part 4.
The above descriptions are merely preferred embodiments of the present invention, is not to make other forms to the utility model
Limitation, any person skilled in the art is changed or is modified as possibly also with the technology contents of the disclosure above equivalent
The equivalent embodiment of change is applied to other fields, but every without departing from the content of the technical scheme of the utility model, according to this reality
Any simple modification, equivalent variations and the remodeling made with new technical spirit to above example, it is new to still fall within this practicality
The protection domain of type technical solution.
