Power distribution station, city installation breakers upper strata fixed frame
Technical field:
The utility model relates to installation breakers upper strata, power distribution station, a kind of city fixed frame.
Background technology:
The power distribution station design in city adopts state's net pattern usually, power distribution station is by distribution transformer, without cabinet compensating cabinet, fall insurance, lightning arrester, the controller switching equipment compositions such as low voltage switch, see Fig. 1, channel-section steel 3 is provided with successively from bottom to top between two wire bars, lower floor's framework 4 of rectangle and upper strata framework 5, channel-section steel, the two ends of lower floor's framework and upper strata framework are fixing on utility poles each via anchor ear, normal mode is that distribution transformer 1 is fixedly mounted on channel-section steel, fall insurance 2 is installed on the framework of Tai Qu upper strata, lightning arrester, low voltage switch 6 is installed on lower floor of platform district framework.In actual implementation process, find on the limit that low voltage switch 6 is only fixed on lower floor's framework firm not, easily loosen after long operational time, the particularly careless slightly installation steadiness that will have influence on on-load switch during the maintenance of platform district, simultaneously, the half of upper strata framework 5 can not install any equipment, is in idle condition, substantially wastes.Above problem all brings very big inconvenience to the construction in platform district and later stage operation maintenance, causes the waste of manpower and financial resources, there is certain potential safety hazard simultaneously.
Summary of the invention:
For overcoming the defect of prior art, the purpose of this utility model is to provide installation breakers upper strata, power distribution station, a kind of city fixed frame, and this frame structure is simply firm, easy for installation, and constructing operation is convenient.
The utility model technical solution problem adopts following technical scheme:
Power distribution station, city installation breakers upper strata fixed frame:
Comprise the upper bracket of horizontal arrangement and be in the lower carriage of the horizontal arrangement below described upper bracket, described upper bracket and lower carriage are U-shaped structure and opening is relative;
Band iron by vertically arranging between the free end of described upper bracket and the free end of lower carriage is fixedly connected with, and is provided with the anchor ear for being fixed by whole fixed frame on utility poles at the free end of described upper bracket and the free end of described lower carriage.
Described upper bracket and lower carriage are made by angle steel, and on described upper bracket, are provided with three for installing the bolt hole of fall insurance, described lower carriage are provided with two or four for installing the bolt hole of low voltage switch.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the lower carriage of this fixed frame and lower floor of Yuan Tai district framework form low voltage switch mounting bracket, and mounting structure is firm, reduces equipment security of operation risk point.
2, processing is simple, and easy for installation, technique is elegant in appearance.
3, be convenient to power distribution station equipment replacement and maintenance, decrease maintenance work risk, ensure device security reliable power supply.
Accompanying drawing illustrates:
Fig. 1 is the mounting structure schematic diagram of existing power supply unit and fixed frame thereof; Fig. 2 is the using state figure of the utility model fixed frame.
Number in the figure: 1 distribution transformer, 2 fall insurances, 3 channel-section steels, 4 lower floor's frameworks, 5 upper strata frameworks, 6 low voltage switchs, 7 upper brackets, 8 lower carriages, 9 anchor ears, 10 band irons.
Below by way of embodiment, and the utility model is described in further detail by reference to the accompanying drawings.
Embodiment:
Embodiment: composition graphs 2, power distribution station, the city installation breakers upper strata fixed frame of the present embodiment, it comprises the upper bracket 7 of horizontal arrangement and is in the lower carriage 8 of the horizontal arrangement below upper bracket, upper bracket 7 and lower carriage 8 is U-shaped structure and opening is relative; Band iron 10 by vertically arranging between the free end of upper bracket and the free end of lower carriage is fixedly connected with, make the side of whole fixed frame be zigzag structure, and be provided with the anchor ear 9 for being fixed by whole fixed frame on utility poles at the free end of upper bracket 7 and the free end of lower carriage 8.
In specifically arranging, upper bracket 7 and lower carriage 8 are made by angle steel, and on upper bracket, are provided with three for installing the bolt hole of fall insurance 2, lower carriage are provided with two or four for installing the bolt hole of low voltage switch 6.
During installation, the whole fixed frame by side being first zigzag adopts four anchor ears 9 to be fixed on electric pole correct position, make the spacing keeping 15mm-25mm between lower carriage 8 and platform district original lower floor framework 4, concrete distance is determined by low voltage switch installing hole, after such lower carriage 8 forms double-layer scaffold with lower floor of platform district framework 4, low voltage switch 6 is secured by bolts in double-layer scaffold, and fall insurance 2 is installed on the centre position of upper bracket 7 by bolt.
