Description
Technical field
The utility model is related to AC-HVDC field of engineering technology, in particular to a kind of non-conductor lightning conducter rod structure.
Background technology
In the transformer station of AC-HVDC and converter station project, the general framework using power distribution equipment is installing lightning conducter
Post, to save occupation of land and investment cost.According to《The overvoltage protection of alternating-current electric device and Insulation Coordination design specification》(GB/T
Requirement 50064-2014), when soil resistivity is more than 350 Ω .m, must not install lightning rod on transformer gate framework, keep away
Thunder line.This be in order to prevent lightning current to transformer equipment cause counterattack.When using rolling specified in IEEE-Std998-2012
When ball carries out the verification of direct lightning strike protection, if installing lightning conducter as shown in figure 1, can not utilize on transformer gate framework 1,
Then transformer region may need to set up lightning conducter using lightning-arrest terminal is installed above other frameworks additional, cause lightning protection to design
And difficulty of construction is increased.If the region electrical equipment characteristics of compact layout, and nearby lightning conducter 5 is installed Wu other frameworks available,
Then need to increase independent lightning protection line tower 7.By taking Fig. 1 as an example, it is computed checking, the lightning-arrest terminal hanging point absolute altitude in 3 top of alternating current inlet wire framework
32m is needed, 7 top lightning conducter hanging point absolute altitude of independent lightning protection line tower needs 32m, terminal hanging point absolute altitude is taken shelter from the thunder in 6 top of independent π type framework need to
30m, terminal hanging point absolute altitude of taking shelter from the thunder above building need 37m, and amounting to needs lightning conducter 8 across being always about 580m.The program causes to increase
The defect of investment cost.
Content of the invention
In the presence of solving the problems, such as above-mentioned existing background technology, the utility model provides a kind of optimization transformer
The non-conductor lightning conducter rod structure of area lightning prevention protecting design.
For achieving the above object, the non-conductor lightning conducter rod structure designed by the utility model, including transformer gate structure
Frame and alternating current inlet wire framework, are provided with commonly terminal of taking shelter from the thunder on the alternating current inlet wire framework, which is characterized in that, the transformation
The two ends of device gate framework are vertically arranged with the lightning-arrest terminal of non-conductor, and the terminal of commonly taking shelter from the thunder is passed through with the lightning-arrest terminal of non-conductor
Lightning conducter connects.
Further, described also include independent π type framework, be also equipped with, on the independent π type framework, terminal of commonly taking shelter from the thunder,
Terminal of commonly taking shelter from the thunder on the independent π type framework is connected by lightning conducter with the lightning-arrest terminal of non-conductor.
Further, the non-conductor takes shelter from the thunder terminal for glass reinforced plastic pipe.The keeping away of fiber winding forming glass reinforced plastic pipe material
Thunder terminal, realizes setting up lightning conducter above transformer gate framework, will not cause counterattack to transformer equipment, optimize transformer
Area lightning prevention protecting is designed.
Further, the height of the lightning-arrest terminal of the non-conductor is 6～10m.
Further, the hanging point height of terminal taken shelter from the thunder by the non-conductor and the distance between lower section hanging wire is 6～10m,
Effective protection is located at the hanging wire below terminal of taking shelter from the thunder.
The utility model passes through to install the lightning-arrest terminal of non-conductor above transformer gate framework, realizes in transformer gate
Lightning conducter is installed on framework, and will not cause counterattack to transformer equipment, effectively solve transformer region cloth in engineering design
Put the independent lightning protection line tower difficulty of compact, setting and neighbouring no lightning protection of other available frameworks to install lightning conducter sets
Meter problem, optimizes the design of transformer region lightning protection, simplifies lightning conducter arrangement, reduces difficulty of construction.
Description of the drawings
Fig. 1 is the structural representation of existing lightning conducter rod structure；
Fig. 2 is the structural representation of the utility model non-conductor lightning conducter rod structure；
In figure：Transformer gate framework 1, non-conductor are taken shelter from the thunder terminal 2, alternating current inlet wire framework 3, terminal 4 of commonly taking shelter from the thunder, and take shelter from the thunder
Line 5, independent π type framework 6, independent lightning protection line tower 7.
Specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
The utility model non-conductor lightning conducter rod structure as shown in Figure 2, including transformer gate framework 1 and alternating current inlet wire structure
Frame 3, is provided with commonly terminal 4 of taking shelter from the thunder on alternating current inlet wire framework 3.The two ends of transformer gate framework 1 are vertically arranged with non-conductor
Lightning-arrest terminal 2, terminal 4 of commonly taking shelter from the thunder are connected by lightning conducter 5 with the lightning-arrest terminal 2 of non-conductor.Also include independent π type framework 6, solely
Terminal 4 of commonly taking shelter from the thunder is also equipped with vertical π type framework 6, commonly take shelter from the thunder terminal 4 and the non-conductor lightning conducter on independent π type framework 6
Post 2 is connected by lightning conducter 5.
The utility model sets up lightning conducter 5 by realizing the top of transformer gate framework 1, on region independence π type framework 6
The common height for taking shelter from the thunder terminal 4 of side can reduce 2m, and every lightning conducter span is greatly reduced, most long in the scheme after improvement
Lightning conducter span shorten to 69m by the 99m of most long lightning conducter span in former scheme, so as to be more beneficial for framework stress；Improvement side
In case lightning conducter by former scheme 8 across be reduced to 7 across, overall length is reduced to 360m by 580m, simplify lightning conducter arrangement；Improvement side
The high independent lightning protection line tower of 32m 1 is saved in case, is saved to take up an area and is saved cost.
Other unspecified parts are prior art.
