Specific embodiment

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to the accompanying drawing and specifically The utility model is described in detail in embodiment.It should be appreciated that specific embodiment described herein is only used to explain this Utility model is not used to limit the utility model.

Ultra-high voltage converter station 800kV disconnecting switch mounting structure as shown in Figure 1, Figure 2, Figure 3 shows mainly includes that the first pipe is female 3, first intersects that aluminium twists ring fitting 4,800kV disconnecting switch 5, second intersects aluminium and twists ring fitting 6 and the second pipe mother 8, and described the One pipe mother 3 is supported by the first 800kV support insulator 1, and the second pipe mother 8 passes through the 2nd 800kV post insulator Son 9 is supported；The first intersection aluminium twists the setting of ring fitting 4 keeps apart in the first 800kV support insulator 1 and 800kV Close between 5, also, described first intersect aluminium twist formed between one end and the first pipe mother 3 of ring fitting 4 conduction connecting structure, The other end and 800kV disconnecting switch form conduction connecting structure between 5 one end.Further, described first intersects aluminium strand ring gold It is that conduction connecting structure is formed by pipe mother anchor ear 11 between one end and the first pipe mother 3 of tool 4；Described first, which intersects aluminium, twists ring gold The other end of tool 4 is connect with connecting plate 12, and described 5 one end of 800kV disconnecting switch is connect with terminal board 13, the terminal board Form conduction connecting structure between 13 and connecting plate 12, as shown in figure 3, to make 800kV disconnecting switch 5 and the first pipe female 3 it Between can by first intersection aluminium twist ring fitting 4 come realize electrical connection.In order to which preferably balanced first pipe mother 3 is intersected with first Aluminium twists the electric field strength of 4 connecting portion of ring fitting and optimizes field distribution, can be at the top of the first 800kV support insulator 1 It is fixedly connected with grading ring bracket 10, the grading ring bracket 10 is fixedly connected with the first grading ring 2, as shown in Figure 2.

Described second intersect aluminium twist the setting of ring fitting 6 the 2nd 800kV support insulator 9 and 800kV disconnecting switch 5 it Between, it is formed between conduction connecting structure, 5 other end of the other end and 800kV disconnecting switch and is formed between one end and the second pipe mother 8 Conduction connecting structure.Further, one end that the second intersection aluminium twists ring fitting 6 is female by pipe mother anchor ear 11 and the second pipe Conduction connecting structure is formed between 8, as shown in Figure 2.Described second intersects the other end and the company of connecting plate 12 that aluminium twists ring fitting 6 It connects, 5 other end of 800kV disconnecting switch is connect with terminal board 13, is formed between the terminal board 13 and connecting plate 12 Conduction connecting structure, as shown in figure 3, to make that aluminium can be intersected by second between 800kV disconnecting switch 5 and the second pipe mother 8 Ring fitting 6 is twisted to realize electrical connection.Intersect aluminium with second for preferably balanced second pipe mother 8 and twists 6 connecting portion of ring fitting Electric field strength and optimize field distribution, grading ring bracket can be fixedly connected at the top of the 2nd 800kV support insulator 9 10, it forms a fixed connection between the grading ring bracket 10 and the second grading ring 7, as shown in Figure 2.

After above-mentioned structure design, intersect aluminium strand ring fitting since the first intersection aluminium therein twists ring fitting 4, second 6 be that electrical connection is realized using two aluminum stranded conductor semi-rings of horizontal direction, in pipe female end by the way of intersecting aluminum stranded conductor Optimize field distribution, by the way that reasonable aluminum stranded conductor semi-ring outer diameter is arranged, make to intersect aluminium twist ring fitting conducting wire be straightened after length Degree is greater than the relative displacement between the two sides power equipment being attached thereto, and can be well realized and is having the same of big displacement stroke When be able to maintain the stability of fitting again.Therefore, the first intersection aluminium can be made full use of to twist ring fitting 4 to come so that 800kV keeps apart Conductive connection between pass 5 and the first pipe mother 3 has biggish displacement amount of redundancy, it is equally possible that making full use of the second friendship Fork aluminium, which twists ring fitting 6, to be come so that the conductive connection between 800kV disconnecting switch 5 and the second pipe mother 8 has biggish displacement redundancy Amount, so as to reduce the mechanical stretching force of 5 circuit of 800kV disconnecting switch connection conductor well to the additional of equipment junction Therefore mechanical stress can be effectively prevented from the first intersection aluminium in seismic process and twist the intersection aluminium strand ring gold of ring fitting 4, second The power equipment for having 6 two sides causes connecting plate deformation impaired due to by additional earthquake mechanical force, improves 800kV and keeps apart The whole shock resistance for closing 5 ontologies and its circuit connection structure ensure that safety, the reliability in 800kV disconnecting switch circuit.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, and should refer to Out, any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention etc. should all include It is within the protection scope of the utility model.
