Abstract
The utility model discloses a kind of rectangular bus bar for high earthquake intensity area and mounting structure thereof, relate to high earthquake intensity area EHV transmission technical field, aim to provide a kind of rectangular bus bar and the mounting structure thereof with certain retractility, to reach the effect of earthquake isolation.The utility model technical essential: rectangular bus bar is provided with at least one bending; The described arc that is bent to bends or rectangular bent; The copper bar of described rectangular bus bar to be thickness be 4 ~ 5mm, described bending is positioned at the plane vertical with thickness direction.
Description
Technical field
The utility model relates to high earthquake intensity area EHV transmission technical field.
Background technology
When building conventional 220kV and following transformer station, 10kV is idle, and power distribution equipment (containing 10kV reactor and 10kV capacitor) equipment room line generally adopts aluminium to arrange such rectangular bus bar 2 is connected, as Fig. 1.When transformer station is built in high earthquake intensity area, 10kV is idle, and power distribution equipment (containing 10kV reactor and 10kV capacitor) is connected if equipment room line still adopts aluminium to arrange, the as easy as rolling off a log impact because of seismic force, two equipment room distances are caused to change, and aluminium row is a kind of hard conductor, there is no retractility, when the change of equipment room distance is large or diminish and all can produce huge tensile force or extruding force to device clamp, and pass to main equipment, especially huge tensile force very easily causes superposition infringement to equipment, and causes device clamp place to be damaged.
Utility model content
Goal of the invention of the present utility model is: for above-mentioned Problems existing, provides a kind of rectangular bus bar and the mounting structure thereof with certain retractility, to reach the effect of earthquake isolation.。
The rectangular bus bar for high earthquake intensity area that the utility model provides is provided with at least one bending.
Preferably, described rectangular bus bar is copper bar.
Preferably, arc bending or rectangular bent is bent to described in.
Preferably, the copper bar of described rectangular bus bar to be thickness be 4 ~ 5mm, described bending is positioned at the plane vertical with thickness direction.
The mounting structure of the idle power distribution equipment rectangular bus bar of a kind of high earthquake intensity area 10kV that the utility model provides, comprises the terminals of the first equipment, the terminals of the second equipment and rectangular bus bar;
One end of described rectangular bus bar is connected with the terminals of the first equipment, and the other end of rectangular bus bar is connected with the terminals of the second equipment;
Described rectangular bus bar is provided with at least one bending.
Preferably, arc bending or rectangular bent is bent to described in.
Preferably, the copper bar of described rectangular bus bar to be thickness be 4 ~ 5mm, described bending is positioned at the plane vertical with thickness direction.
Preferably, the described rectangular bus bar width be positioned on vertical direction is greater than the thickness be positioned in horizontal direction.
Preferably, also comprise post insulator, described rectangular bus bar level frame is located on post insulator.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are:
Rectangular bus bar in the utility model is provided with bending, effectively increases the nargin receiving tensile force distortion of hard conductor.When an earthquake occurs, equipment room there occurs displacement, the rectangular bus bar in the utility model is stretched accordingly or shrinks, available protecting device clamp.
Rectangular bus bar in the utility model erects to connect between devices, and because the width be positioned on vertical direction is greater than the thickness be positioned in horizontal direction, the anti-recessed ability of rectangular bus bar is improved significantly.

Mark in figure: 1 is post insulator; 2 is existing rectangular bus bar; 3 is the rectangular bus bar in the utility model; 31 is arc bending; 32 is rectangular bent.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment one
As shown in Figure 2, the rectangular bus bar 3 in figure is erected between two post insulators 1.Rectangular bus bar is provided with at least one bending.Bending 31 in the present embodiment is circular arc.
Described rectangular bus bar is preferably as thickness is the copper bar of 4 ~ 5mm, and described bending is positioned at the plane vertical with thickness direction.
The rectangular bus bar that the present embodiment provides is installed between two equipment, and one end of rectangular bus bar is connected with the terminals of the first equipment, and the other end of rectangular bus bar is connected with the terminals of the second equipment.
Resisting recessed ability to increase rectangular bus bar, as Fig. 3, rectangular bus bar being erect and lays, making the described rectangular bus bar width be positioned on vertical direction be greater than the thickness be positioned in horizontal direction.
Post insulator in Fig. 3 is for supporting rectangular bus bar, and rectangular bus bar level frame is located on post insulator.
Embodiment two:
See Fig. 4, in the present embodiment, the bending 32 of rectangular bus bar is rectangle.
Set forth the principle that the utility model can play antidetonation, function of shock insulation below:
Suppose that certain transformer station's seismic fortification intensity is 7 degree, 10kV is idle, and power distribution equipment equipment room line adopts rectangular bus bar.According to the utility model content, it is 50mm that the ampacity in rectangular bus bar foundation loop is selected wide, and thick is 4mm cross section copper bar, stands up between the equipment of being arranged in.Two equipment rooms are apart from 1m, this section of bus arranges the semi arch bending of two diameter 0.25m, two equipment room rectangular bus bar total lengths are about 1.3m, the nargin increasing about about 0.3m is arranged compared with normal dia, come interim at seismic force, the tensile force that earthquake causes first can be stretching by the semi arch on copper bar, and can not cause damage to equipment.
