Description

One can wire jumper strain insulator string
Technical field
The utility model belongs to electric power network field of tool, particularly relate to a kind of for difference tower can wire jumper strain insulator string.
Background technology
Two difference lines of difference tower had two schemes when hanging over the both sides of same row's cross-arm in the past:
(1) first connect consistent with about a wherein difference line for main line, then by two difference line short circuits, drainage adopts the fixing windage yaw preventing composite insulator in top to fix, but this mode of connection must make a wherein left line of difference line connect with the right line of main line, the right line of difference line connects with the left line of main line, namely changes the left and right sequence of two loop lines, when line maintenance is safeguarded, if only road has a power failure once, be prone to accidents.
(2) above cross-arm wire is example, article two, the wire inside difference line nearby with main line about two wires connect and draw, article two, the wire outside difference line connects with another root main line respectively and draws, jumper string is formed by 2 suspension insulators are end to end, be suspended on outside difference cross-arm central authorities, two drainages are passed from upper and lower two wire clamps of insulator chain respectively.Although sequence is consistent with main line about this wire jumping method makes difference line, the method not only makes 2 drainages intersect, and the jumper string in outside easily swings with the wind, there is serious potential safety hazard.
There is no can easily swinging with the wind for solving above-mentioned jumper string by wire jumper strain insulator string of a kind of good structure at present, there is the problem of serious potential safety hazard.
Utility model content
Technical problem to be solved in the utility model is to provide one to prevent jumper string from easily swinging with the wind, and that avoids security hidden trouble can wire jumper strain insulator string.
The utility model realizes like this, one can wire jumper strain insulator string, comprise and be in duplex strain insulator string group A on a horizontal line and duplex strain insulator string group B and connected as one by adjustment plate, adjustment plate arranges multiple hanging hole, when wire erection is complete, the hanging hole of adjustment plate is horizontal direction, adjustment plate arranges wind-deviation wire jumper insulator chain C, insert in the hanging hole of adjustment plate by the bolt on the top of wind-deviation wire jumper insulator chain C, vertical with described duplex strain insulator string group A and duplex strain insulator string group B.
Further, described duplex strain insulator string group A or duplex strain insulator string group B is parallel-connection structure to the utility model scheme.
Further, described adjustment plate is inverted triangle structure to the utility model scheme, and duplex strain insulator string group A and duplex strain insulator string group B are connected by the adjustment plate that two drift angles are corresponding, are flexibly connected between two adjustment plates by connector.
Compared with prior art, beneficial effect is the utility model: the left and right sequence that the utility model can realize both sides difference line is consistent with main line, can avoid having an accident when primary Ioops power failure operation.Utilize the installation wire jumper insulator chain of insulator chain itself, do not change the structure of steel tower itself.The windage yaw preventing composite insulator that jumper string adopts top fixing, prevents drainage from swinging.Ensure that the drainage of different circuit does not intersect.
Accompanying drawing explanation
Fig. 1 is the device structure schematic diagram that the utility model embodiment provides;
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
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.
As shown in Figure 1 with Figure 2, one can wire jumper strain insulator string, comprise and be in duplex strain insulator string group A1 on a horizontal line and duplex strain insulator string group B3 and adjust plate 2 and connect as one, duplex strain insulator string group A1 or duplex strain insulator string group B3 is parallel-connection structure.Duplex strain insulator string group A1 comprises single insulator chain A7 and single insulator chain B8 parallel-connection structure, duplex strain insulator string group B3 comprises single insulator chain C10 and single insulator chain D11 parallel-connection structure, single insulator chain A7 be connected after single insulator chain B8 parallel connection on an adjustment plate 2, being connected to after single insulator chain C10 is in parallel with single insulator chain D11 adjusts on plate, adjustment plate arranges multiple hanging hole, adjustment plate 2 is inverted triangle structure, duplex strain insulator string group A1 and duplex strain insulator string group B3 are connected by the adjustment plate 2 that two drift angles are corresponding, be flexibly connected by connector 9 between two adjustment plates.
When wire erection is complete, the hanging hole of adjustment plate 2 is horizontal direction, adjustment plate 2 arranges wind-deviation wire jumper insulator chain C5, insert in the hanging hole of adjustment plate by the bolt 4 on the top of wind-deviation wire jumper insulator chain C5, vertical with described duplex strain insulator string group A and duplex strain insulator string group B.Wind-deviation wire jumper insulator chain C arranges fixture 6 for conducting wire.
In the present embodiment, duplex strain insulator string group A and duplex strain insulator string group B is connected as one by adjustment plate, when wire erection is complete, the hanging hole of adjustment plate is horizontal direction, the bolt on wind-deviation wire jumper insulator chain top is inserted the hanging hole of adjustment plate, adjustment wind-deviation wire jumper insulator chain is to direction straight down, and by bolt tightening, adopt the difference tower of this strain insulator-string only the primary Ioops in the difference line of inner side need be installed by this strain insulator-string, the left and right of both sides difference line can be made to sort consistent with main line, and the achiasmate situation of drainage.Wind-deviation wire jumper insulator chain is arranged on adjustment plate, utilizes the combination of gold utensil and the tension force of wire to make jumper string keep stable.
The utility model structure is used for the red good fortune first and second line 36# that Dandong-six directions T to connect in iron ore ditch 66kV line project new group vertical and adopts this wire jumper scheme, the inner side cross-arm of the difference line of drawing left uses the utility model structure, jumper string adopts the fixing wind-deviation wire jumper insulator chain C in top to be fixed on this strain insulator-string adjustment plate, and it is consistent that two double loop difference lines that the program makes difference tower relatively draw and main line keep left and right to sort.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
