Care for the convenience of repair and maintenance.General change of current valve tower can have structural member highlight installation shielding pressure knot in each corner and centre
Structure, needs to cover certain area, area is usually larger, needs to tear open when repair and maintenance submodule due to shielding equal laminated structure
Unload.With the continuous lifting of voltage class and capacity, valve tower height is constantly increased, therefore shielding is dismantled during repair and maintenance submodule
Equal laminated structure difficulty also continues to increase.
Utility model content
The purpose of this utility model, is that providing a kind of rotary type change of current valve tower shields equal laminated structure, it can solve to change
The shielding voltage-sharing of valve tower is flowed, while convenient and efficient can be removed in repair and maintenance submodule.
In order to achieve the above objectives, the solution of the utility model is：
A kind of rotary type change of current valve tower shields equal laminated structure, including shielding grading shield, mounting bracket assembly and locking limit
Position hinge, wherein, mounting bracket assembly is installed on valve tower frame, and one end of locking limit hinge is installed on mounting bracket assembly
On, the other end be installed on shielding grading shield on, shielding grading shield by locking limit hinge rotatably with mounting bracket assembly
It is connected.
Above-mentioned mounting bracket assembly includes left socle, right support and middle support, wherein, the both ends of middle support connect respectively
Left, stent, so that mounting bracket assembly is in integrally I-shaped, one end of left and right stent is individually fixed in valve tower frame, another
End connects locking limit hinge respectively.
The other end of above-mentioned left and right stent is connected respectively one end of two locking limit hinges, and two shieldings are pressed
Cover is connected respectively the other end of two locking limit hinges.
Above-mentioned mounting bracket assembly is connected by screw fixation with valve tower frame.
Above-mentioned shielding grading shield, mounting bracket assembly, locking limit hinge are metallic article.
After using the above scheme, the beneficial effects of the utility model are：
(1) the utility model is while meeting that change of current valve tower shields equal pressure request, when the son for needing repair and maintenance to be blocked
During module, corresponding shielding grading shield need to be only rotated, without in high aerial dismounting shielding grading shield.
(2) it is easy to operate, compact-sized, meet the resistance to electromagnetic interference of change of current valve tower, uniform surrounding electric field functional requirement.

Embodiment
Below with reference to attached drawing, the technical solution of the utility model is described in detail.
As shown in Figure 1, the utility model, which provides a kind of rotary type change of current valve tower, shields equal laminated structure, including shielding is pressed
Cover 101, mounting bracket assembly 102 and locking limit hinge 103, wherein, each part of mounting bracket assembly 102 leads between each other
Cross fastener to connect to form a reliable component of intensity, on valve tower frame；One end installation of locking limit hinge 103
On mounting bracket assembly 102, the other end is installed on shielding grading shield 101, and shielding grading shield 101 passes through locking limit hinge
103 are connected with mounting bracket assembly 102.
Fig. 2 is the structure diagram of mounting bracket assembly 104, and the mounting bracket assembly 104 includes left socle 201, the right side
Stent 203 and middle support 202, wherein, one end of middle support 202 connects the stage casing of left socle 201, middle support by fastener
202 other end connects the stage casing of right support 202 by fastener, so that the entirety of mounting bracket assembly 104 is in I-shaped,
One end of left and right stent is individually fixed in valve tower frame, and the other end connects locking limit hinge 103 respectively.
The specific installing process of the utility model is：
First, mounting bracket assembly 102 is assembled, 202 3 left socle 201, right support 203, middle support parts are mutual
Between connected by fastener.
Then, 103 one end of locking limit hinge is installed in mounting bracket assembly 102, the other end is in shielding grading shield 101.
Finally, mounting bracket assembly 102 and valve tower frame are connected by screw fixation, so far complete the rotary type change of current
Valve tower shields the assembling and installation of equal laminated structure.
Fig. 3 is the shielding rotating structure diagram of grading shield in the utility model.
The utility model is in use, each ground of shielding grading shield or so is installed on mounting bracket by locking limit hinge
Component both sides, shielding grading shield are flattened in valve tower normal operation, and when need to overhaul submodule, the rotatable side shield grading shield is extremely
120 degree of positions.
Locking limit hinge energy locking when shielding grading shield and being in flat, when need to rotate shielding grading shield,
Shielding grading shield unlock is touched toward rotation opposite direction, is rotated to the locking once again of hinge at 120 degree, need to recover to press shielding case extremely
During flat, unlock is touched to rotation opposite direction, opens and need not dismantle any part during closing shielding case.
The shielding grading shield, mounting bracket assembly, locking limit hinge are metal parts, and are connected with each other, therefore
Shielding grading shield naturally with equipotential at the valve tower frame installed.
Above example is only to illustrate the technological thought of the utility model, it is impossible to the protection model of the utility model is limited with this
Enclose, it is every according to the utility model proposes technological thought, any change done on the basis of technical solution, each falls within this reality
Within the scope of novel protected.
