Abstract
The utility model discloses a wire heightening cross arm device. The device is characterized in that a short supporting main material and a long supporting main material are longitudinally connected with the two sides of the top end of a tower through two pairs of hoops; an edge-phase wire cross arm is fixedly horizontally connected with the middle parts of the short supporting main material and the long supporting main material; one side of the top end of the short supporting main material is fixedly connected with an upwarp middle-phase wire cross arm; and a ground wire cross arm is fixedly connected with the top end of the long supporting main material. The device is connected with the tower into a whole body, and a wire and a ground wire are lifted above the top of the tower, so that a wire crossing distance is increased, and the equipment investment is reduced. The wire cross arm arrangement problem of a special tower with tower height limitation is solved.
Description
Technical field
The utility model relates to the electric force pole tower technical field, is specifically related to a kind of lead for the 35kV circuit and increases the cross-arm device.
Background technology
Cross-arm is ingredient important in the shaft tower, and its effect is that insulator and gold utensil are installed, and with support wire, lightning conducter, and makes it the safe distance that keeps certain in accordance with regulations.Original 35kV line conductor below raises because of the construction road surface or newly-built circuit passes through old lead, and cause former circuit scissors crossing distance not meet the safety code requirement, often adopt the method for changing high shaft tower for this reason, improve lead scissors crossing distance, lengthened power off time, increase the weight of the cost of overhaul, caused a large amount of wastes and loss.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of lead of reasonable in design to increase the cross-arm device, under the prerequisite of not changing shaft tower, solve former circuit scissors crossing apart from the problem of deficiency, reduce power off time, reduce the cost of overhaul.
The technical scheme that its technical problem that solves the utility model adopts is: the both sides, top at shaft tower vertically are connected with short main material and the long support master material of supporting by two pairs of anchor ears, many abdomen materials are connected short the support between main material and the long support master material, be connected with limit phase conductor cross-arm in the short middle part crosswise fixed that supports main material and long support master material, be fixedly connected with the middle phase conductor cross-arm that upwarps in short top one side that supports main material, top at long support master material is fixedly connected with the ground wire cross-arm, the termination of phase conductor cross-arm and limit phase conductor cross-arm during the lead suspension arrangement is located at respectively, link is located at the below of ground wire cross-arm.Described short main material, long support master material, limit phase conductor cross-arm, middle phase conductor cross-arm and the ground wire cross-arm of supporting all adopts ∠ 75 * 8 Zinc-coated angle steels.
By above setting, the utility model connects as one with shaft tower under the situation of occupying few shaft tower length, and lead and ground wire are risen to more than the head of mast, has improved circuit scissors crossing distance, has reduced equipment investment.For the special shaft tower of restriction tower height, solved the Layout Problem of its lead cross-arm.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, shaft tower, 2, anchor ear, 3, shortly support main material, 4, long support master material, 5, limit phase conductor cross-arm, 6, middle phase conductor cross-arm, 7, the lead suspension arrangement, 8, the ground wire cross-arm, 9, link, 10, the abdomen material.
The specific embodiment
As shown in Figure 1, the utility model vertically is connected with short main material 3 and the long support master material 4 of supporting in the both sides, top of shaft tower 1 by two pairs of anchor ears 2, many abdomen materials 10 are connected short the support between main material 3 and the long support master material 4, be connected with limit phase conductor cross-arm 5 in the short middle part crosswise fixed that supports main material 3 and long support master material 4, be fixedly connected with the middle phase conductor cross-arm 6 that upwarps in short top one side that supports main material 3, top at long support master material 4 is fixedly connected with ground wire cross-arm 8, the termination of phase conductor cross-arm 6 and limit phase conductor cross-arm 5 during lead suspension arrangement 7 is located at respectively, link 9 is located at the below of ground wire cross-arm 8.Described short main material 3, long support master material 4, limit phase conductor cross-arm 5, middle phase conductor cross-arm 6 and the ground wire cross-arm 8 of supporting all adopts ∠ 75 * 8 Zinc-coated angle steels.
By above setting, the utility model takies shaft tower 1 space seldom, hangs lead and ground wire, can effectively lead be intersected, and crosses over distance, has improved the line security reliability.
Claims (2)
1. lead is increased the cross-arm device, it is characterized in that: the both sides, top at shaft tower vertically are connected with short main material and the long support master material of supporting by two pairs of anchor ears, many abdomen materials are connected short the support between main material and the long support master material, be connected with limit phase conductor cross-arm in the short middle part crosswise fixed that supports main material and long support master material, be fixedly connected with the middle phase conductor cross-arm that upwarps in short top one side that supports main material, top at long support master material is fixedly connected with the ground wire cross-arm, the termination of phase conductor cross-arm and limit phase conductor cross-arm during the lead suspension arrangement is located at respectively, link is located at the below of ground wire cross-arm.
