Detailed description of the invention
By making, architectural feature of the present utility model and effect of being reached are had a better understanding and awareness, coordinate detailed description in order to preferred embodiment and accompanying drawing, be described as follows:
As shown in Figure 4, described in the utility model a kind of for 500kV and the Chinese character pin-shaped GIS outlet arrangement of following electric pressure, including GIS device 10 and outlet structure 1, outlet structure 1 uses existing frame construction, i.e. include triangular beam 2 and lower triangular beam 3, lightning conducter 8 is installed at outlet structure 1 top.
The outgoing line side of upper triangular beam 2 is provided with B phase strain insulator string 9, and the outgoing line side of upper triangular beam 2 is that angle based on upper triangular beam 2 is set out and said, in station, angle is set out, it is outgoing line side；If for setting out based on outer angle of standing, being inlet wire side, the position concept that i.e. inlet wire side and outgoing line side are expressed in existing saying is identical, is based only on different angles different with the saying at visual angle.The B phase strain insulator string 9 of upper triangular beam 2 outgoing line side is used for hanging B phase conductor 14, and in the upper triangular beam 2 other side in addition to outgoing line side, is then provided with main transformer strain insulator string 15, and main transformer strain insulator string 15 is for hanging the cross-line to main transformer framework.The lower section of upper triangular beam 2 is provided with B phase upside-down mounting support insulator 4, and B phase upside-down mounting support insulator 4 is equally used for lead-in wire and uses.
As shown in Figure 4 and Figure 5, the outgoing line side of lower triangular beam 3 is provided with A phase strain insulator string 18 and C phase strain insulator string 19, and A phase strain insulator string 18 is used for hanging A phase conductor (not marking in figure), and C phase strain insulator string 19 is used for hanging C phase conductor 16.Based on the side that outgoing line side is contrary, B phase cross arm insulator 5 is installed on lower triangular beam 3, the installation site of B phase cross arm insulator 5 is positioned at the opposite side of lower triangular beam 3 outgoing line side, and the hitch point of A phase strain insulator string 18 is corresponding with the fixing point of B phase cross arm insulator 5 with the central point of the hitch point of C phase strain insulator string 19.Central point on i.e. A phase strain insulator string 18 hitch point and C 2 straight lines formed of phase strain insulator string 19 hitch point, is the corresponding relation both sides of B phase cross arm insulator 5 (A phase strain insulator string 18 hitch point and the C phase strain insulator string 19 are positioned at) with the fixing point of B phase cross arm insulator 5.
Owing to the hitch point of A phase strain insulator string 18 and C phase strain insulator string 19 is positioned at the outgoing line side of lower triangular beam 3, and the fixing point of B phase cross arm insulator 5 is positioned at the opposite side of lower triangular beam 3, then lead-in wire during by B phase conductor 14 based on A phase conductor and C phase conductor 16 for draw backward.The hitch point of the fixing point of B phase cross arm insulator 5, the fixing point of B phase upside-down mounting support insulator 4 and B phase strain insulator string 9 is positioned on same longitudinal profile, and three coordinates the lead-in wire for B phase conductor 14.Based on the design of safe distance between A phase strain insulator string 18 and C phase strain insulator string 19 between A phase conductor and C phase conductor 16, the needs of safe distance can be met, wire jumper 6 based on B phase conductor 14 and downlead 7 draw backward, increase the lateral separation between itself and the lead-in wire of the lead-in wire of A phase conductor and C phase conductor 16, thus reach the requirement of safe distance.As shown in Figure 5, A phase strain insulator string 18, C phase strain insulator string 19 and B phase strain insulator string 9 three is that isosceles triangle arranges arrangement, distance when " yi word pattern " being arranged verifies from one-dimensional conversion for two dimension, one-dimensional distance verification outlet structure width is equal to the phase distance of the spaced apart edged phase of three-phase, and the distance verification outlet structure of two dimension is equal to the phase distance of three-phase spaced apart projection edged phase on outlet structure line, therefore, on the basis of meeting the verification of electrical safety clear distance equally, have compressed outgoing line interval width, decrease GIS device main bus-bar length, thus greatly reduce the floor space of transformer station, and reduce GIS device cost.
As shown in Figure 6, GIS device 10 is drawn by A phase outlet casing tube 11, B phase outlet casing tube 12 and C phase outlet casing tube 13, this can be seen that, owing to designing after the drawing of B phase conductor 14, A phase outlet casing tube 11, B phase outlet casing tube 12 and C phase outlet casing tube 13 three also arrange in isosceles triangle at depression angle.As shown in Figure 4, B phase conductor 14 passes sequentially through B phase strain insulator string 9, B phase upside-down mounting support insulator 4 and B phase cross arm insulator 5 dangles, and transition is connected to B phase outlet casing tube 12, B phase conductor 14 is initially mounted on B phase strain insulator string 9 and causes B phase cross arm insulator 5 by wire jumper 6 through the suspension of B phase upside-down mounting support insulator 4, then causes B phase outlet casing tube 12 by B phase cross arm insulator 5 through downlead 7.A phase conductor is connected to A phase outlet casing tube 11 by prior art manner by A phase strain insulator string 18 transition of dangling, C phase conductor 16 is connected to C phase outlet casing tube 13 by prior art manner by C phase strain insulator string 19 transition of dangling, thus completes the introducing of three-phase conducting wire.
Time actually used, when A phase, B phase, C phase three-phase conducting wire enter the station, C phase conductor 16 and A phase conductor hangs respectively and is arranged on C phase strain insulator string 19 and A phase strain insulator string 18, is re-introduced into C phase the outlet casing tube 13 and A phase outlet casing tube 11 of GIS device 10.B phase conductor 14 hangs and is arranged on B phase strain insulator string 9, now C phase conductor 16, A phase conductor have formed dislocation the most spatially with B phase conductor 14, B phase conductor 14 guides backward through B phase upside-down mounting support insulator 4 and B phase cross arm insulator 5 again, access B phase outlet casing tube 12, thus form spatial offset, it is ensured that the requirement of wire electrical safety distance.
Of the present utility model ultimate principle, principal character and of the present utility model advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; simply principle of the present utility model described in above-described embodiment and description; on the premise of without departing from this utility model spirit and scope, this utility model also has various changes and modifications, and these changes and improvements both fall within the range of claimed this utility model.The protection domain that this utility model requires is defined by appending claims and equivalent thereof.
