Description

The integral structure of sub-lead spacer and support
Technical field
The utility model is about a kind of structure of conductor spacer for overhead transmission line, relates in particular to a kind of six oidiospore lead spacer for inter-phase spacer sealing layout and the integral structure of support.
Background technology
At present, a large amount of transmission lines adopts the inter-phase spacer sealing to arrange as circuit wind-deviation and the measure of waving; As shown in Figure 4, inter-phase spacer 91 is general is called for short sub-conductor spacer by sub-lead spacer 92() be connected with wire, support 93 generally is installed on sub-lead spacer 92, support 93 is connected on inter-phase spacer 91.
Three-phase conducting wire can be connected to become by three inter-phase spacers 91 and supporting sub-conductor spacer 92 triangular structure of a sealing.for 500kV compact line (conductor structure is six split forms), the sub-lead spacer 92 that this sealing triangular form adopts and the syndeton of support 93 are as shown in Figure 5, one of common feature of this syndeton is, on each sub-conductor spacer 92, two supports 93 are installed, support 93 passes through bolt with sub-conductor spacer 92, pin or other links are connected, each support 93 has two connecting portions with sub-conductor spacer 92, and two supports 93 share a connecting portion on sub-conductor spacer 92, as shown in Figure 5, wherein position A and position B are two connecting portions of a support 93, position C and position B are two connecting portions of another support 93, position B is two supports 93 share on sub-conductor spacer 92 a connecting portion., for the 500kv compact line,, although the version of the sub-conductor spacer that adopts and support is various,, for connecting simultaneously the form of two inter-phase spacers on a sub-conductor spacer, be all but that two supports are installed on a sub-conductor spacer.Described sub-conductor spacer material of main part is generally cast aluminium, and middle nearly hexagon dish is that monolithic or biplate aluminium sheet are made, and support is generally aluminum.
, by a large amount of operating experience and the test of experiment porch, two supports are installed on a sub-conductor spacer, because two supports need a public tie point (connecting portion B), and two support total weights are larger, therefore, when installing at the scene, difficulty is larger; In addition, in the process of operation, be subject to for a long time the tensile force f of two different angles supports due to this tie point (as position B in Fig. 6) 1, F 2, in running long-term impact and pull under, this position is very easily damaged; Be subject to separately the power of different directions due to two supports, and two supports are connected at a point (position B point), when the power of a direction is excessive, can cause whole conductor spacer significantly to twist, thereby to support, cause very large moment of torsion, and then damage support; Some the accidents that support, sub-conductor spacer rupture have appearred in North China Power Telecommunication Network in recent years, and damaged location concentrates on position B and support arm place.
From the above mentioned, there is following shortcoming in prior art:
(1) due to two supports being installed on a sub-conductor spacer simultaneously, the support total weight is larger, and is therefore, more difficult when install in high-altitude at the scene; In addition, two supports need a public installing hole on sub-conductor spacer, need higher cooperation during installation, have further strengthened the field erected difficulty of support.
(2) two supports are connected with sub-conductor spacer by A, B, 3 of C, when support is subject to F 1And F 2In the time of two active forces, these two power can be by the support direct effect to sub-conductor spacer A, B, three application points of C, and wherein B point was subject to simultaneously from the making a concerted effort of two supports, should be larger with joint efforts, thereby make the B point become the weak spot of sub-conductor spacer, very easily damage; , as force-summing element independently, be delivered to the power of support due to two supports by inter-phase spacer, can be all by the support direct effect to sub-conductor spacer, make sub-conductor spacer A, B, three application points of C bear for a long time larger power.
(3) when support is subject to the depth direction external force of the Z-direction (as shown in Figure 6) that inter-phase spacer passes over, the moment of depth direction is concentrated and is acted on A, B, the connection pin at C point place, making this connecting portion is the application point of moment, A, B, the C point is used for offsetting to the opposing torque of pin the moment that inter-phase spacer transmits fully, especially the B point is received the moment of flexure that comes from both direction simultaneously, the moment of flexure that this point is subject to becomes multiple to increase, and because sub-conductor spacer is fixed on wire, make A, B, the C point is difficult to produce displacement with the motion of support in the Z direction, this makes A, B, the opposite force at C point place is relatively large, easily cause the damage of sub-conductor spacer, , concentrate while acting on A, B, C point place in the moment from the depth direction as force-summing element independently due to support, support arm also is subject to from the huge moment of flexure of depth direction.
(4) the sub-conductor spacer that extensively adopts at present, still adopt stereotype design standard, only consider to play the supporting role between sub-conductor, consider comprehensively stressed when being subject to inter-phase spacer pulls, therefore, can there be hidden danger in direct assorted golden tool as inter-phase spacer.
Thus, the inventor, by means of being engaged in experience and the practice of relevant industries for many years, proposes the integral structure of a kind of sub-lead spacer and support, to overcome the defect of prior art.
