Abstract
The utility model relates to a 10kV urban power distribution network high-low rod type overhead device, which comprises a 10kV oil-immersed distribution transformer, a low-voltage distribution box, a high support rod and a low support rod. Two horizontal support steel channels are fixedly connected between the lower portion of the high support rod and the top of the low support rod, the distribution transformer is arranged on the two horizontal support steel channels, and a low-voltage casing pipe of the 10kV oil-immersed distribution transformer is connected with the low-voltage distribution box by an electric cable. The overhead device is modified in that the low-voltage casing pipe of the transformer is positioned on the lateral surface, and the low-voltage distribution box is positioned at the bottoms of the two horizontal support steel channels or on the ground. The 10kV urban power distribution network high-low rod type overhead device has the advantage of capabilities of not only improving power supply reliability of a distribution network system, but also realizing easy equipment installation and wiring for installation personnel, reducing work load of the installation personnel, simultaneously beautifying urban environment, saving investment in rods and frames, reducing floor area of distribution network equipment, saving urban land resources, realizing expansibility and reserving space for further development.
Description
Technical field
The utility model belongs to power supply and distribution facility, is specifically related to 10kV urban electric power distribution aerial construction.
Background technology
10kV urban electric power distribution aerial construction and layout thereof are because there are a lot of problems in historical reasons at present: the city power supply and distribution facility is outmoded, and aerial construction is aging serious; Mostly operating distribution transformer is with two overhead line poles together support, adopt mounting means on the post, the hack lever work difficulty is big, lead-in wire is complicated, it is big to take up room, and its high and low pressure side turnover line is close and numerous as cobweb, and this has had a strong impact on the overall appearance in a city; Simultaneously distribution transformer high-pressure side lightning arrester and on-pole switch are installed separately, and cause installing very inconvenient and cause node too much, and it is overheated easily to take place, and has increased the possibility of apparatus insulated destruction, thereby has reduced the power supply reliability of distribution.
Summary of the invention
Existing 10kV urban electric power distribution aerial construction facility is outmoded, aging seriously, layout is unreasonable, influence is attractive in appearance and the deficiency of power supply reliability difference in order to overcome, and the utility model provides a kind of 10kV urban electric power distribution single pole pole aerial construction.
Concrete Technological improvement plan is as follows:
10kV urban electric power distribution height rod-type aerial construction, comprise 10kV oil immersion-type distribution transformer, low-tension distribution box, a high support bar and a low support bar, fixedly connected two horizontal support channel-section steels between high support bar bottom and the low support bar top, described transformer is located on two horizontal support channel-section steels, and the low-tension bushing of 10kV oil immersion-type distribution transformer is connecting low-tension distribution box by cable;
The low-tension bushing of described 10kV oil immersion-type distribution transformer is positioned at the side,
Described low-tension distribution box is positioned at two horizontal support channel-section steel bottoms or is positioned at ground.
The utility model mainly goes out on the basis of line type structure in 10kV oil immersion-type distribution transformer low-tension bushing side, wiring, mounting arrangement to 10kV urban electric power distribution aerial construction are optimized and safety Design, design two cover height rod-type aerial construction schemes altogether; Its useful technique effect is, not only improved the power supply reliability of distribution network systems, but also make installation personnel be easy to erection unit and wiring, reduce the workload of installation personnel, also beautified urban environment simultaneously, save the bridge investment, reduce the distribution net equipment floor space, save the land resource in city, and had extensibility, kept further development space.
