Description
Technical field
The utility model relates to for electrical domain, refers to especially a kind of twin columns steel pipe pole with lightning protection.
Background technology
Along with the sustainable development of Chinese national economy, urban power consumption increases suddenly, will get more and more at the 110kV of urban spraw ultra-high-tension power transmission line.Because cable run involves great expense, China can't generally adopt at present, so inevitable take overhead wire as main.
The feature of steel pipe pole is mainly that conductor cross-section is large, multiple voltage, loop bar altogether, and available corridor is narrow and small, is often positioned at side, street or isolation flower bed, and root is opened very little.Because steel pipe pole floor space is little, handsome in appearance, can incorporate well urban environment, therefore in urban electricity supply construction, be used widely.
Utility model content
The utility model proposes a kind of twin columns steel pipe pole with lightning protection, can bear larger load of roadway than single-column steel pipe bar, be more suitable for using when the large high-tension line of preload.
The technical solution of the utility model is achieved in that
With a twin columns steel pipe pole for lightning protection, its agent structure comprises:
Shaft, is fixedly formed by multiple horizontally disposed connecting portions by two steel pipe columns;
Described connecting portion comprises crossbeam and two ends, and two described ends are for fixing two steel pipe columns of described shaft;
The top position of described shaft is provided with multiple cross-arms, for setting up power line;
Lightning protection, comprises the arrester that is placed in described shaft top, and described arrester connects the down lead that is built in described steel pipe column and described cross-arm, and described down lead connects netted ground device.
Described ground device is embedded under earth's surface.Described ground device is wire lath, as iron net, copper mesh etc.Wire lath can be that plane structure can be also stereochemical structure.
In technique scheme, two ends of described connecting portion adopt be nested with described steel pipe column outside and with suitable connecting portion cylinder or the multiple connecting portion annulus formation of described steel pipe column external diameter.
In technique scheme, described steel pipe column is formed by fixedly connecting by multistage steel pipe.
Further, described steel pipe can be seamless steel pipe or ERW.
Further, every two sections of described steel pipes can be fixedly connected with by flange, also can be fixedly connected with by screw or bolt, or be welded and fixed.
In technique scheme, described connecting portion crossbeam is steel pipe crossbeam or steel plate crossbeam.
In technique scheme, the length of the multistage steel pipe of composition steel pipe column not equates, be positioned at steel pipe column on the lower the length of every section of steel pipe at position can be greater than the length of the every section of steel pipe that is positioned at steel pipe column middle and upper part.
In technique scheme, described cross-arm can be arranged on connecting portion place, can certainly be arranged on other positions of steel pipe column pipe shaft.
In technique scheme, described cross-arm can adopt the symmetrical structure centered by shaft, and preferably adopts triangle.
In sum, because the utility model has adopted two steel pipe columns, and use multiple connecting portions to reinforce, and there is netted ground device, make it can either bear larger line load and kept again steel pipe pole simplicity generosity, advantage handsome in appearance, and there is good lightning protection properties.

The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As depicted in figs. 1 and 2, the twin columns steel pipe pole with lightning protection of the present utility model, its agent structure comprises:
Shaft, is fixedly formed by multiple horizontally disposed connecting portions 7 by two steel pipe columns 1;
Described connecting portion 7 comprises crossbeam 6 and two ends, and two described ends are for fixing two steel pipe columns 1 of described shaft;
The top position of described shaft is provided with multiple cross-arms 4, for setting up power line;
Lightning protection, comprises the arrester 10 that is placed in described shaft top, and described arrester 10 connects the down lead 8 that is built in described steel pipe column 1 and described cross-arm 4, and described down lead 8 connects netted ground device 9.
Described ground device 9 is embedded under earth's surface.Described ground device 9 is wire laths, as iron net, copper mesh etc.Wire lath can be that plane structure can be also stereochemical structure.
