The specific embodiment
Below in conjunction with the performance of accompanying drawing detailed description the utility model, but they do not constitute the qualification to the utility model, only do for example.Advantage through explanation the utility model will become clear more and understanding easily simultaneously.
Consulting accompanying drawing can know: the dried font anchor support of the utility model extra-high voltage direct-current single loop, and it is horizontal dried font iron tower, comprising: body of the tower 11; Lead cross-arm 13; Ground line bracket 14, tower leg 15, jumper wire rack 16; Said horizontally be wire jumper hanging point 23 on the lead cross-arm 13 for horizontally, the dried font that said anchor support 1 is appeared is that body of the tower 11, the tower leg 15 of two ground line brackets 14 of horizontal direction, two lead cross-arms 13 and vertical direction constructed the dried fonts that appear jointly.
The tower leg height that the height of tower leg 15 vertically installs said anchor support 1 for the landform of ground being installed according to said anchor support 1; The height of tower leg 15 can be all or part of identical; Also can have nothing in common with each other, the height of tower leg 15 can design according to the landform of the actual installation of anchor support 1.Through adopting omnibearing unequal leg 15, can reduce the opening of mountain area column foot face, do not destroy the landform and the vegetation in mountain area, be beneficial to environmental protection.
Body of the tower 11 extends the top of said tower leg 15, and the axis 110 of said body of the tower 11 is vertical basically with horizontal plane.
Electric clearance mainly is presented as the distance of lead hanging point and body of the tower on shaft tower, electric pressure is high more, and this required distance is big more.With respect to 500kV and following transmission line of electricity, the body of the tower 11 of UHV transmission anchor support 1, lead cross-arm 13, ground line bracket 14 is all wanted corresponding amplifying with tower leg 15.The size design of body of the tower 11 will take into full account the lead cross-arm 13 of increase; The burden that ground line bracket 14 brings for body of the tower 11; In addition; The adverse effect that the form that bad weathers such as strong wind, low temperature, icing can increase to load brings for whole anchor support 1, body of the tower 11 also will fully take into account these influence factors when design.
The shielding angle of said anchor support 1 is negative shielding angle; Ground wire hanging point 24 on the promptly inboard ground line bracket 14 and the distance L 1 of the distance W 1 of axis 110 greater than lead hanging point on the lead cross-arm 13 of inboard 22 and axis 110, and the distance W 2 of ground wire hanging point on the ground line bracket 14 in the outside 24 and axis 110 is greater than the distance L 2. of the lead hanging point on the lead cross-arm 13 in the outside 22 with axis 110
Less than the gradient of body of the tower below its bottleneck 111, the said gradient is the angle that the lateral surface of body of the tower 11 is become with vertical direction to said body of the tower 11 in the gradient above its bottleneck 111.The voltage that anchor support 1 is transmitted is high more, and its overall dimensions also can be big more, and diameter of wire is also just big more.Consider that anchor support 1 needs the load of vertical direction and the tension force of horizontal direction, body of the tower 11 needs the suitable gradient of design to make whole anchor support 1 can resist suffered load, and makes the shaft tower steel quantity consumption minimum.The gradient of body of the tower 11 below its bottleneck 111 is greater than the stressing conditions that meets whole tower body greater than its gradient above bottleneck 111.
During the design anchor support, emphasis is each scantling of design tower head (part of bottleneck more than 111), guarantees that the tower head of design satisfies the electric clearance requirement of Ultra-high Voltage Wire., again by the height of exhaling of the said anchor support 1 of the corresponding increase of design demand.W3 is front and back wire jumper string spacings among Fig. 2.
For different extra-high voltages, the formed gap of transmission pressure circle size is difference to some extent also, and corresponding, the each several part size of anchor support 1 needs adjust according to concrete extra-high voltage.
Concrete, a kind of specific embodiment of anchor support when the utility model provides extra-high voltage grade ± 800kV, with reference to Fig. 1, the high H that exhales of said anchor support 1 is 30-51m; The last plane of ground line bracket 14 and the lower plane of lead cross-arm 13 are 15m apart from K; Limit lead hanging point 22 on the inboard cross-arm 13 is 11.2m with the distance L 1 of axis 110, and the limit lead hanging point 22 on the outside cross-arm 13 is 12.2m with the distance L 2 of axis 110.Ground wire hanging point on the line bracket 14 24 is 12.95m with the distance W 1 of axis 110 medially.Ground wire hanging point 24 on ground, the outside line bracket 14 is 13.95m with the distance W 2 of axis 110.The bottleneck width P of anchor support 1 is 4.8m.The open top width E of body of the tower 11 is 2.568m.
The inventor has designed one sequence ± employed anchor support of 800kV direct current extra-high voltage, and the correlated performance parameter is seen table 1.
Table 1
The size of each the model anchor support 1 described in the table 1 is when the electric clearance of satisfied ± 800kV direct current UHV transmission requires; The load recurrence interval of being designed is 100 years; Coefficient for importance of structure gets 1.1, and transmission pressure adopts 6 * ACSR-720/50, and ground wire adopts LBGJ-180.
The steel of anchor support 1 adopt Q420, Q345 and three kinds of materials of Q235.The shaped steel that anchor support 1 adopts is steel pipe and angle steel, and lead cross-arm 13 is an angle steel with ground line bracket 14, and all the other members are steel pipe.
The extra-high voltage anchor support that this use is novel, tower head size can satisfy the electric clearance requirement of UHV transmission; And through reasonable structural design and selection; Make the extra-high voltage anchor support have enough mechanical strengths; Bear because the whole tower body size that the lead trade mark increases and electric pressure raises to be caused becomes the increase of the big various loads that bring, and reduce the use amount of tower body steel.
The preferred embodiments that the above is merely the utility model is not the protection domain that is used to limit the utility model.Any modification of being done within all spirit and principles at the utility model is equal to replacement, improvement etc., all is included in the protection domain of the utility model.
