Abstract
The utility model relates to a tension rod cross arm. The tension rod cross arm comprises a first cross arm, wherein one end of the first cross arm is provided with screw holes which are used for installing porcelain bottles. The tension rod cross arm is characterized in that the other end of the first cross arm is fixedly connected with a second cross arm, the first cross arm and the second cross arm are connected in a T-shaped structure, and two ends of the second cross arm are both provided with screw holes which are used for installing porcelain bottles. The tension rod cross arm can enlarge distances between guide lines and ground easily and conveniently.
Description
Technical field
The utility model relates to a kind of strain insulator bar cross-arm.
Background technology
In the high ferro power supply station rural power grids project of upgrading and rebuilding, need lead LJ-25/35/50 be replaced by the JKLYJ-10KV-70 insulated wire, according to the rules, the insulated conductor line directly for 70mm and more than, cross-arm need install support iron additional.The workmen meets difficulty when installing support iron additional to corner strain insulator bar cross-arm more than 30 °; Because of this strain insulator bar all adopts double-deck and above cross-arm, to form by two angle bar for every layer, the strain insulator bar all designs the unobstructed place at road; The general 10M electric pole that adopts, the cross-arm spacing is generally between 0.75M to 1M.According to the regulation of design, electric pole buried depth 1.7M, top shroud ring 0.1M; Cross-arm and middle top apart from 0.75M; Between support point and lower floor's cross-arm of support iron apart from 0.75M, descend the layer conductor hitch point to have only 6.7M in theory apart from ground so, consideration lead sag generally is designed to about 0.8M; Actual lead distance to the ground has only 5.9M, is less than the safe distance of 6.5M.Solve the not enough problem of distance to the ground, existing method is that electric pole is replaced by 12M and above electric pole, and changing electric pole then needs great amount of manpower and financial resources.
Summary of the invention
The purpose of the utility model provides a kind of strain insulator bar cross-arm that can strengthen the lead distance to the ground simply and easily.
For realizing above-mentioned purpose, the technical scheme that the utility model provides is a kind of strain insulator bar cross-arm; It comprises first cross-arm; One end of first cross-arm is provided with the screw hole that is used to install porcelain vase, it is characterized in that, the other end of first cross-arm is fixedly connected with second cross-arm; First cross-arm and second cross-arm are the T font, and the two ends of second cross-arm are equipped with the screw hole that is used to install porcelain vase.
The both ends of described second cross-arm are respectively by drawing the iron and first cross-arm to fix.
Compared with prior art; The beneficial effect of the utility model is: the utility model is merged into a pair with two pairs of cross-arms; Original two-layer cross-arm is merged into one deck (promptly lacking one deck cross-arm); Reduce cross-arm spacing 0.75M, make original lead distance to the ground 5.9M be increased to 6.65M, surpassed safe distance 6.5M.

Fig. 4 is the overall schematic of the utility model;
Among the figure: 1-first cross-arm, 2-second cross-arm, 3-draw iron, 4-porcelain vase, 5-screw hole.
Embodiment
Like Fig. 1, Fig. 2, Fig. 3, shown in Figure 4; A kind of strain insulator bar cross-arm; The other end that it comprises first cross-arm 1, second cross-arm 2, draw an end of iron 3, the first cross-arms to be provided with is used to install screw hole 5, the first cross-arms 1 of porcelain vase 4 is fixedly connected with second cross-arm 2; First cross-arm 1 and second cross-arm 2 are T font (formation T-shape), and the two ends of second cross-arm 2 are equipped with the screw hole 5 that is used to install porcelain vase 4.
The both ends of described second cross-arm 2 are respectively by drawing the iron 3 and first cross-arm 1 fixing (playing booster action).Draw the iron 3 and first cross-arm 1 or second cross-arm 2 all to be 45.
Claims (2)
