Current existing outdoor power distribution unit structure is more complicated, and stability of strutting system is poor.
summary of the invention:
The purpose of this utility model is the support providing a kind of outdoor power distribution unit, and the supporting structure of this outdoor power distribution unit is simple, reasonable in design, and supporting & stablizing is firm.
The support of the utility model outdoor power distribution unit, it is characterized in that: comprise two cement vertical rod, from top to bottom 4 layers be located between two cement vertical rods be trapped in soil layer and carry on a shoulder pole bars and be positioned at two cross-arms below the most next layer load bar, wherein go up support on cross-arm and be provided with transformer, lower cross-arm supports and is provided with switchbox; High pressure threephase cable is accessed respectively on cement vertical rod top, threephase cable connects respectively to be positioned at after the second layer carries on a shoulder pole the isolating switch on bar, the arrester on the 4th layer of load bar and is connected with transformer high-voltage end of incoming cables, the outlet of transformer low voltage leading-out terminal is by connecting the lead-in wire terminal toward switchbox after pvc pipe socket, the low-pressure line-outgoing of inducer for line outlet end of transformer exports after being positioned at the insulator on third layer load bar.
Further, above-mentioned cement vertical rod bottom is provided with cement terminal pad, this cement terminal pad is a rectangle cement block, lower cross-arm is connected with grounded round steels, this grounded round steels lower end and the ground connection Bolted angle connection be laterally embedded in soil layer, be connected with buried grounding flat steel in soil layer below ground connection angle steel.
Further, above-mentioned two vertical rods are provided with some pipe holders for supporting pvc pipe and the line bracket for supporting low-pressure line-outgoing.
The support of the utility model outdoor power distribution unit, by 4 layer load bars between two cement vertical rods and two cross-arms be positioned at below the most next layer load bar, is wherein gone up support on cross-arm and is provided with transformer, lower cross-arm supports and is provided with switchbox; High pressure threephase cable is accessed respectively on cement vertical rod top, threephase cable connects respectively to be positioned at after the second layer carries on a shoulder pole the isolating switch on bar, the arrester on the 4th layer of load bar and is connected with transformer high-voltage end of incoming cables, the outlet of transformer low voltage leading-out terminal is by connecting the lead-in wire terminal toward switchbox after pvc pipe socket, the low-pressure line-outgoing of inducer for line outlet end of transformer exports after being positioned at the insulator on third layer load bar, thus makes the stability of strutting system of power equipment, wind resistance better.

detailed description of the invention:
The support of the utility model outdoor power distribution unit, comprise two cement vertical rod 1, from top to bottom 4 layers be located between two cement vertical rods 1 be trapped in soil layer to carry on a shoulder pole bars 2 and be positioned at two cross-arms 4 below the most next layer load bar, wherein go up support on cross-arm 401 and be provided with transformer 5, lower cross-arm 402 supports and is provided with switchbox 6; High pressure threephase cable 7 is accessed respectively on cement vertical rod top, threephase cable connects respectively to be positioned at after the second layer carries on a shoulder pole the isolating switch 8 on bar 202, the arrester 9 on the 4th layer of load bar 204 and is connected with transformer 5 high pressure end of incoming cables, the outlet of transformer low voltage leading-out terminal is socketed the lead-in wire terminal of rear connection toward switchbox 6 by pvc pipe 10, and the low-pressure line-outgoing of inducer for line outlet end of transformer exports after being positioned at the insulator 11 on third layer load bar 203.
Further, in order to stable connection is reliable, above-mentioned cement vertical rod bottom is provided with cement terminal pad 12, this cement terminal pad 12 is a rectangle cement block, lower cross-arm 402 is connected with grounded round steels 13, this grounded round steels lower end is connected with the horizontal ground connection angle steel 14 be embedded in soil layer, is connected with buried grounding flat steel 15 in soil layer below ground connection angle steel 14.
Further, above-mentioned two vertical rods are provided with some pipe holders 16 for supporting pvc pipe and the line bracket 17 for supporting low-pressure line-outgoing.
In the plane at two cement vertical rod center line places, two cement vertical rod center lines form the angle of 5 degree, and wherein upper end is close to each other.
4 layers carry on a shoulder pole the angle that bar 2 forms 8 degree between two from top to bottom in addition, and namely load bar and two cement vertical rods are formed trapezoidal between two.
The support of the utility model outdoor power distribution unit, by 4 layer load bars between two cement vertical rods and two cross-arms be positioned at below the most next layer load bar, is wherein gone up support on cross-arm and is provided with transformer, lower cross-arm supports and is provided with switchbox; High pressure threephase cable is accessed respectively on cement vertical rod top, threephase cable connects respectively to be positioned at after the second layer carries on a shoulder pole the isolating switch on bar, the arrester on the 4th layer of load bar and is connected with transformer high-voltage end of incoming cables, the outlet of transformer low voltage leading-out terminal is by connecting the lead-in wire terminal toward switchbox after pvc pipe socket, the low-pressure line-outgoing of inducer for line outlet end of transformer exports after being positioned at the insulator on third layer load bar, thus makes the stability of strutting system of power equipment, wind resistance better.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
