Abstract
The utility model relates to an inverted F-shaped insulated tower used for electric network power transmission line, comprising a tower, a cross arm, and the cross arm is connected with the upper part of the tower in a shape of Chinese character 'Shang', and the tower, the cross arm are all formed by hollow tubes or solid rods which are squeezed or winded by fiber glass. And the terminal end of the cross arm is provided with a metal fitting, and the metal fitting is provided with a hanging hole. The cross arm, the tower are all insulating rod body, therefore, the power transmission line is directly connected with the hanging hole at the terminal end of the cross arm, the problem of distance between the power transmission line and the tower, the cross arm can not be considered, the length of the cross arm and the tower is significantly shortened, the occupied area and the installation height for the whole insulated tower are reduced, meanwhile, the manufacturing cost is reduced. The silicon rubber coat can be covered onto the cross arm, therefore, the creepage distance of the insulated tower can be increased, and the safety performance of the insulated tower can be improved.
Description
Technical field
The utility model relates to a kind of insulation tower, is specifically related to a kind of compound inslation tower that is used to set up the grid power transmission line.
Background technology
The insulation tower is used to support the high voltage power transmission electrical network, and it is made of metal system body of the tower and cross-arm usually, and installs insulator string additional at the end of cross-arm, and high voltage transmission line then hangs over the end of insulator string.Under the wind-force effect, power line is vacillated now to the left, now to the right, and swings when asynchronous when the power line of shaft tower both sides, can cause that the air gap punctures between power line, thereby flashover between line takes place, and causes whole electrical network to jump electricity, influences people's normal electricity consumption.Therefore when tower is insulated in design; usually the distance between cross-arm and the cross-arm can be arranged on bigger safe range; but it proposes higher requirement to intensity of body of the tower, cross-arm, increases the floor space and the cost of manufacture that have increased whole insulation tower after the length of cross-arm simultaneously.
The utility model content
The technical problems to be solved in the utility model provides a kind of grid power transmission line and uses font insulation tower, and it can avoid the influence of wind-force to power line, reduces the length of shaft tower and cross-arm, can reduce the floor space and the cost of manufacture of insulation tower.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of grid power transmission line is used font insulation tower, and it comprises shaft tower, cross-arm, and described cross-arm is presented the top that font is connected shaft tower; Its innovative point is: described shaft tower and cross-arm are glass fiber pultrusion or the hollow section that is wound in or solid bar and constitute; Described shaft tower is connected with cross-arm by metal connecting piece, and described shaft tower is connected with cross-arm by metal connecting piece with cross-arm global formation or shaft tower.
Further, the end of described cross-arm is with metal-ware, has suppending hole on described metal-ware.
Further, described metal connecting piece is the pair of metal member, and this is to respectively establishing a flange on the hardware, and two flanges are bolted to connection and are one.
Further, described cross-arm is coated with insulating coating.
Advantage of the present utility model is: described cross-arm and shaft tower are the insulation body of rod, when setting up the power line of electrical network, power line directly is connected in the suppending hole of cross-arm end, under the condition that guarantees the good insulation between power line and power line and the ground, the length of cross-arm and the height of shaft tower have been reduced, reduce the floor space and the setting height(from bottom) of whole insulation tower, reduced cost of manufacture simultaneously.Can coat silastic material on the cross-arm, can increase the creep age distance of insulation tower, improve the security performance of insulation tower.
Description of drawings
Fig. 1 uses the structural representation of font insulation tower for grid power transmission line of the present utility model.
Fig. 2 is the structural representation of metal connecting piece of the present utility model.
The specific embodiment
Insulation tower of the present utility model comprises shaft tower 1, cross-arm 2, metal connecting piece 4, metal-ware 10, suppending hole 3.
Above-mentioned shaft tower 1, cross-arm 2 are insulation materials and constitute.Concrete, shaft tower 1, cross-arm 2 are glass fiber pultrusion or the hollow section that is wound in or solid bar and constitute, and cross-arm 2 and shaft tower 1 can global formations, also can link into an integrated entity by metal connecting piece 4 for split type.
Described as shown in Figure 1 split type, cross-arm 2 is presented font and is installed on the shaft tower 1, and fixedly connected by metal connecting piece 4: metal connecting piece 4 is a pair of metal member 5,6, be enclosed within the end of cross-arm 2 and shaft tower 1 junction respectively, and it is fixedly connected by bonding adhesive, be provided with flange 7,8 on hardware 5,6, described flange 7,8 is fixedly connected by bolt 9, can be referring to Fig. 2.The end of cross-arm 2 is with metal-ware 10 equally, and fixes by bonding adhesive, has suppending hole 3 on described metal-ware 10, and power line can be bearing on the shaft tower 1 by suppending hole 3.
Because cross-arm 2, shaft tower 1 are insulation materials, therefore insulation tower of the present utility model needn't be considered the Insulation Problems of cross-arm 2, shaft tower 1 and power line, can directly power line be fixed on the end of cross-arm 2, owing to be fixed on the shaft tower 1 during cross-arm 2, power line is very little with the influence swing of wind-force, can reduce the length of cross-arm 2, the manufacturing materials of both having saved has reduced whole floor space again.Because the use of having saved insulator string, the distance of power line directly becomes the distance between the cross-arm 2 up and down up and down, and therefore the distance between the cross-arm 2 can be established reducing of working as up and down, thereby has reduced the overall height of shaft tower 1.
In order to increase the creep age distance of insulation tower, improve the security performance of insulation tower, also can outside cross-arm 2, coat one deck insulating coating again.
