The technical problems to be solved in the utility model is realized using following technical scheme: a kind of ultra-high voltage converter station is neutral
Line wall bushing damping installation structure, including neutral conductor wall bushing, intersection aluminium twist ring fitting and neutral conductor pole bus, described
Neutral conductor pole bus is supported by neutral conductor support insulator, and the intersection aluminium twists ring fitting and is arranged in neutral conductor pillar
Between insulator and neutral conductor wall bushing and intersect aluminium twist ring fitting opposite end respectively with neutral conductor wall bushing, in
Property line pole bus formed conduction connecting structure.
Preferably, described one end for intersecting aluminium strand ring fitting is connect with connecting plate, described neutral conductor wall bushing one end
It is connect with terminal board, forms conduction connecting structure between the terminal board and connecting plate.
Preferably, conduction connecting structure is formed by connection bolt between the terminal board and connecting plate.
Preferably, the other end for intersecting aluminium strand ring fitting is led by being formed between pipe mother anchor ear and neutral conductor pole bus
Electric connection structure.
Preferably, the intersection aluminium twists ring fitting and is obliquely installed relative to neutral conductor wall bushing.
Preferably, it is formed between the neutral conductor pole bus and neutral conductor support insulator by the fixed fitting of pipe mother solid
Determine connection structure.
Preferably, arranged in parallel between the neutral conductor wall bushing and neutral conductor pole bus.
Compared with prior art, the utility model has the beneficial effects that twisting the setting of ring fitting in neutrality by the way that aluminium will be intersected
Between line support insulator and neutral conductor wall bushing, and keep the opposite end for intersecting aluminium strand ring fitting through walls with the neutral conductor respectively
Casing, neutral conductor pole bus form conduction connecting structure, realize the neutral conductor so as to make full use of to intersect aluminium and twist ring fitting
Wall bushing ontology and its be electrically connected circuit damping, and guarantee the neutral conductor wall bushing electrical connection circuit stability,
Reliability very well satisfies displacement request and electrical attachment requirements between the power equipment under earthquake operating condition, effectively improves
Neutral conductor wall bushing ontology and its anti-seismic performance for being electrically connected circuit, and then avoid the damage of electric power facility, have
Good economic benefit.

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 neutral conductor wall bushing damping installation structure as shown in Figure 1 mainly includes that the neutral conductor is through walls
Casing 1 intersects aluminium and twists ring fitting 3 and neutral conductor pole bus 5, and one end of the neutral conductor wall bushing 1 is through valve hall 2 and outer
It is exposed to valve hall 2, the neutral conductor pole bus 5 is supported by neutral conductor support insulator 6, neutral conductor set through walls
It is arranged in parallel between pipe 1 and neutral conductor pole bus 5.In general, the top of the neutral conductor support insulator 6 is fixedly connected with pipe
The fixed fitting 4 of mother, so that neutral conductor pole bus 5 can be by forming between the fixed fitting 4 of pipe mother and neutral conductor support insulator 6
Fixed connection structure is conducive to the connective stability, the reliability that improve neutral conductor pole bus 5.
The intersection aluminium twists ring fitting 3 and is arranged between neutral conductor support insulator 6 and neutral conductor wall bushing 1, and
And the opposite end for intersecting aluminium strand ring fitting 3 forms conductive connect with neutral conductor wall bushing 1, neutral conductor pole bus 5 respectively
Binding structure.Further, as shown in Figure 2 and Figure 3, it is described intersect aluminium twist ring fitting 3 one end connect with connecting plate 7, the other end then
By forming conduction connecting structure between pipe mother anchor ear 10 and neutral conductor pole bus 5, described 1 one end of neutral conductor wall bushing with
Terminal board 8 connects, and forms conduction connecting structure between the terminal board 8 and connecting plate 7.The terminal board 8 and connecting plate 7
Between preferably by connection bolt 9 formed conduction connecting structure, not only guarantee be conductively connected reliability, but also easy disassembly make
Industry.
It is two aluminium using horizontal direction since intersection aluminium therein twists ring fitting 3 after above-mentioned structure design
Twisted wire semi-ring is electrically connected to realize, optimizes field distribution by the way of intersecting aluminum stranded conductor in pipe female end, passes through setting and closes
The aluminum stranded conductor semi-ring outer diameter of reason, the length after the conducting wire for intersecting aluminium strand ring fitting is straightened are greater than the two sides electric power being attached thereto and set
Relative displacement between standby, can be well realized the stability for being able to maintain fitting again while having big displacement stroke.Into
One step, the intersection aluminium twists ring fitting 3 and is preferably obliquely installed relative to neutral conductor wall bushing 1.Accordingly, it is possible to fill
Divide and twists ring fitting 3 using intersection aluminium come so that 1 ontology of neutral conductor wall bushing and its electrical connection circuit have biggish displacement
Amount of redundancy is electrically connected the mechanical stretching force in circuit to equipment junction to reduce neutral conductor wall bushing 1 well
Additional machinery stress guarantees to efficiently avoid the deformation damage that neutral conductor wall bushing 1 is electrically connected circuit junction
Neutral conductor wall bushing 1 ontology and its it is electrically connected the safety in circuit, reliability.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, and should refer to
