Description
Technical field
The utility model relates to high voltage power transmission and transforming engineering design technology field, specifically, particularly relates to a kind of HGIS power distribution equipment and side direction outlet structure thereof.
Background technology
500kV HGIS(Hybrid Gas-Insulated Switchgear, compound combined electrical equipment) be one of 500kV power distribution equipment pattern of widely being used at present.General 3/2 breaker connection that adopts of 500kV power distribution equipment, winding diagram correspondence shown in Fig. 1～3 have represented conventional outlet method and the knock-on outlet method of existing 500kV power distribution equipment.
Fig. 1, Figure 2 shows that conventional outlet, wherein the line segment with arrow represents outlet, and Fig. 1 is vertical bus direction outlets of two outlets in the string, and Fig. 2 is an outlet vertical bus direction outlet, another outlet parallel bus direction outlet, and non-cross leap on the plane of earthward projection.
Figure 3 shows that the knock-on outlet, wherein the line segment with arrow represents outlet, i.e. the reverse outlet of an outlet vertical bus direction in the string, another outlet parallel bus direction outlet, two outlets scissors crossing on the plane of earthward projection.
In general, 500kV HGIS power distribution equipment often adopts the medium-sized layout of suspension type hard pipe bus HGIS three row.The cross-line two-layer is arranged cross-line in (outlet method of corresponding diagram 1) or bus, the string, high-rise cross-line three-layer type layout (outlet method of corresponding diagram 2) in general employing bus, the string, outlet structure, intermediate frame, bus framework adopt the association type framework closely to link to each other, and arrangement is very compact.Fig. 4 is three layers of arrangement sectional drawing of typical HGIS.The layout of its compactness has to a certain degree limited the flexibility of arranging, the difficult side direction that realizes is hanged down frame outlet and knock-on outlet, to joining string and arranging the formation restriction.Arrange that routinely two transmission line circuits such as main transformer inlet wire and circuit outlet can't scissors crossing in the string, is difficult to realize knock-on.
The HGIS routine is arranged as three-layer type and arranges, realize low frame outlet, must increase by a layer conductor routinely on bus again, arranges thereby reach four laminars.But the framework height of the superiors had reached 33.5 meters during three-layer type was arranged, as increasing one deck, the framework height will further increase, and not only strengthen the design difficulty of framework, also be unfavorable for operation maintenance again.
HGIS then just can realize the outlet of bouncing with another outlet in the string if realize the low frame outlet of side direction, can make join go here and there and arrangement more flexible, reasonable.
Therefore, how not changing under the condition that has the framework height now, realizing the low frame outlet of HGIS power distribution equipment and knock-on outlet, is the emphasis of optimization power distribution equipment.
Thus, with respect to two kinds of conventional outlet methods as shown in Figure 5, wherein the line segment with arrow represents outlet, overhead side direction outlet and conventional outlet, four-headed arrow represents generatrix direction among the figure, and people develop again the outlet method of two kinds of outlets that can realize bouncing, such as Fig. 6, shown in Figure 7, four-headed arrow represents generatrix direction among the figure, represents outlet with the line segment of arrow.Wherein, prior art shown in Figure 6 has increased a transition string to be exclusively used in outlet for realizing HGIS knock-on outlet; But this mode that realizes the knock-on outlet by increasing framework will increase floor space and construction investment.Prior art shown in Figure 7 is that the HGIS knock-on adds the crossings on different level outlet, in the interval, increase bogie frame, after the outlet high level bounces in the interval, utilize this bogie frame, become the knock-on outlet, but this mode has increased frame design difficulty and steel using amount, and simultaneously high-rise cross-line is complicated, is not easy to operation maintenance.
Summary of the invention
Based on this, the utility model is to overcome the defective of prior art, and a kind of side direction outlet structure and a kind of HGIS power distribution equipment of HGIS power distribution equipment is provided, and realize the simultaneously low frame outlet of side direction and knock-on outlet, and framework is simple, steel using amount is few.
