Description
Technical field
The utility model belongs to power distribution equipment technical field, is related to a kind of arrangement of 220kV power distribution equipments.
Background technology
GIS（Cubicle Gas-Insulated Switchgear）Substation equipment is due to its reliability height, high safety, occupation of land face
Product is small, is very suitable for the construction of intelligent power network, but according to《GB 50260-2013 code for design of seismic of electrical installations》：
" electric utility in the important electric power facilities of 1.0.9 ... can improve 1 degree by seismic fortification intensity and set up defences, but seismic fortification intensity
No longer to be improved when 9 degree and the above.", " 6.2.6 ... installed in transformer, reactor body on part, dynamic response
Amplification coefficient should take 2.0.", " 6.7.2 fixture wires and equipment room line preferably use flexible circuit conductor, and its length should leave surplus.When
During using hard bus, should there are flexible circuit conductor or expansion joint transition." according to the requirement of State Grid Corporation of China project of transmitting and converting electricity design,
The GIS device of standard is directly connected to transformer connected mode for oil-gas casing, but is found in use due to area
Difference, this standardized designs are not particularly suited for some regional transformer substation constructions, and some areas have the ring of high earthquake intensity
Border feature, is directly connected to using oil-gas casing, it is impossible to meets shockproof requirements.
GIS is connected with transformer using oil-gas casing in the prior art.Oil-gas casing is not easy to GIS and transformer manufacturers
Match somebody with somebody, machining accuracy is high, and equipment cost is high, and mounting cost is high.
Utility model content
To solve the above problems, the utility model provides a kind of 22kV GIS and transformer attachment structure.
The purpose of this utility model is realized in the following manner：
A kind of 220kV GIS and transformer attachment structure, transformer are respectively arranged in independent interval with 220kV GIS
Interior, bushing shell for transformer use oil-casing air, and 220kV GIS power transfer conduit is led in transformer room through compartment
Top, 220kV GIS outlet casing tubes pass through using inverted casing air and with the three-phase leading-out terminal of the casing air of transformer
Flexible circuit conductor is electrically connected.
Power transfer conduit in described 220kV GIS rooms is fixed on the roof of transformer room.
Power transfer conduit in described 220kV GIS rooms, close to partition wall one on the side on the downside of the pipeline of 90 ° of corners
Support frame is set.
Relative to prior art, the attachment structure of a kind of 220kV GIS of the utility model and transformer, meet specification antidetonation
Design requirement, influence of the transformer vibrations to other equipment in running is avoided, is also prevented from drawing bad equipment during earthquake.
Brief description of the drawings
Fig. 1 is structure section figure of the present utility model.

Fig. 3 is B-B sectional drawings in the utility model Fig. 1.
Wherein 1 is 220kV GIS rooms, and 2 be transformer room, and 3 be 220kV GIS casing airs, and 4 be transformer air set
Pipe, 5 be flexible circuit conductor, and 6 be support frame.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in figure 1, the attachment structure of a kind of 220kV GIS and transformer, transformer and 220kV GIS be respectively arranged in
In independent compartment, bushing shell for transformer uses oil-casing air, and 220kV GIS power transfer conduit leads to change through compartment
Top in depressor room, 220kV GIS outlet casing tubes are using inverted casing air 3 and with the three of the casing air 4 of transformer
Phase leading-out terminal is electrically connected by flexible circuit conductor 5.
Power transfer conduit in described 220kV GIS transformer rooms is suspended to the top of transformer room.Described 220kV
Power transfer conduit in GIS transformer rooms is setting support frame 6 on the side close to the one of partition wall on the downside of the pipeline of 90 ° of corners.
Above-described is only preferred embodiment of the present utility model, it is noted that for those skilled in the art
For, under the premise of the utility model general idea is not departed from, some changes and improvements can also be made, these should also be considered as
The scope of protection of the utility model.
