Pull out and compare, most long to add 5 sub-pieces, the length of 1 sub-pieces is 170mm, and the length of 5 sub-pieces is
850mm, so as to add the length of suspension insulator.And height above sea level 2500m is, after the amendment of the air gap, electrical equipment is most
Small safety net distance requires A1 >=4550mm, A2 >=6100mm, increases than minimum safe clear distance A1 >=3800mm in height above sea level 1000m
Add 750mm, A2 >=4550mm increase 1550mm, in order to meet each air gap distance requirement after height above sea level amendment, 500kV HGIS
Power distribution equipment outlet structure has to increase height, the too high invisible increase civilwork engineering quantity of outlet structure.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of 500kV HGIS distribution suitable for height above sea level 2500m
Device, to reduce the quantities of framework construction.
The technical solution adopted in the utility model is：A kind of 500kV HGIS power distribution equipments suitable for height above sea level 2500m, bag
HGIS equipment, frame assemblies and lead are included,
The frame assemblies include inlet wire framework and outlet structure；Inlet wire cross-arm is installed on the inlet wire framework, it is described
Outlet cross-arm is installed on outlet structure；Inlet wire strain insulator string and inlet wire pendency insulation are installed in one end of inlet wire cross-arm
Substring；First outlet strain insulator string, the second outlet strain insulator string and outlet are installed in one end of outlet cross-arm to hang
Hang down insulator chain；The inlet wire suspension insulator and outlet suspension insulator are V-shaped；
The lead includes inlet wire wire jumper, middle wire jumper and outlet wire jumper；
Described middle wire jumper one end is connected to inlet wire strain insulator string, and the other end is connected to the first outlet strain insulator
String；
The inlet wire wire jumper draws after the mounting of HGIS equipment, inlet wire suspension insulator and inlet wire strain insulator string successively
To middle wire jumper；
The outlet wire jumper is resistance to by the first outlet strain insulator string, outlet suspension insulator and the second outlet successively
Outlet is led to after opening insulator chain mounting.
Preferably, the angle of the inlet wire suspension insulator is 18 °~25 °.
Preferably, the sub-pieces number of the inlet wire suspension insulator is 37~39.
The beneficial effects of the utility model are：The utility model, due to inlet wire suspension insulator and outlet pendency insulation
Substring is V-shaped, reduces the boom length of inlet wire suspension insulator and outlet suspension insulator, is hanged with the I shapes of routine
Vertical insulator chain is compared, and reduces the height of inlet wire framework and outlet structure.Meanwhile the inlet wire suspension insulator of V-arrangement and go out
Line suspension insulator is more firm to the fixation of corresponding wire jumper, and " windage yaw that can also reduce itself is waved, while can also be reduced corresponding
The windage yaw rocking tendency of wire jumper, can reduce that wire is alternate, relatively distance, so as to reduce corresponding framework width；Therefore use
The suspension insulator of V-arrangement can not only reduce framework height, moreover it is possible to reduce framework width, play and reduce the same of framework amount
When, save floor occupying area.
Brief description of the drawings
Fig. 1 is the utility model schematic diagram；
Fig. 2 is progress suspension insulator, suspension insulator schematic diagram occurs.
In figure, inlet wire framework 1, outlet structure 2, inlet wire cross-arm 3, outlet cross-arm 4, inlet wire strain insulator string 5, inlet wire hang
Hang down insulator chain 6, the first outlet strain insulator string 7, the second outlet strain insulator string 8, outlet suspension insulator 9, enter
Line wire jumper 10, middle wire jumper 11, outlet wire jumper 12.
Embodiment
