Preferably, the aluminum stranded wires in the connecting piece 3 are used as current carrying conductors, and generally comprise 4-6 aluminum stranded wires, and the specific number and the specific type of the aluminum stranded wires are determined by the maximum current carrying capacity of the pipe bus. Under the condition that no earthquake occurs, namely when the combined hardware fitting is under the normal working condition, each aluminum stranded wire is in an S shape, so that when two aluminum stranded wires are combined, an 8-shaped cross structure is formed, and two ends of each aluminum stranded wire are respectively connected with the pipe nut 1 and the pipe nut 5.
Preferably, taking the equalizing ring assembly 4 as an example (the structure of the other equalizing ring assembly 2 is the same as that of the equalizing ring assembly 4), referring to fig. 2, fig. 2 is a schematic structural diagram of an equalizing ring assembly in a combined hardware according to an embodiment of the present invention; the equalizing ring assembly 4 comprises a first circular ring 41, a second circular ring 43 and a bracket 42 for fixing the first circular ring 41 and the second circular ring 43; wherein, the liquid crystal display device comprises a liquid crystal display device,
the bracket 42 is arranged between the first circular ring 41 and the second circular ring 43, and the bracket 42 is used for connecting one end of the pipe nut 5 so as to fix the equalizing ring assembly 4 on the pipe nut 5; the first ring 41 and the second ring 43 are both closed.

Namely, the grading ring assembly 2 and the grading ring assembly 4 are staggered in a crossing way, so that collision can not occur when the grading ring assembly and the grading ring assembly are relatively close to each other under the earthquake working condition.
Preferably, referring to fig. 2, the combined hardware further includes a wire clamp 7, the wire clamp 7 is disposed on a port of the pipe nut 5, the wire clamp 7 is used for fixing the aluminum stranded wires (the pipe nut 1 is also provided with a wire clamp 7 with the same structure as the pipe nut 5), and two ends of each aluminum stranded wire are respectively connected with the wire clamp 7 to realize connection between the pipe nut 1 and the pipe nut 5.
Preferably, the combined hardware further comprises post insulators, the post insulators are in one-to-one correspondence with the grading ring assemblies, and the post insulators are connected with the fixing pieces 6 to support the combined hardware.
Referring to fig. 3 to 4, in a normal working condition, the horizontal length of the aluminum stranded wire connecting the pipe nut 1 and the pipe nut 5 is L1.
When an earthquake occurs, see fig. 3, the pipe die 1 and the pipe die 5 are relatively far apart, and the equipment to which the pipe die 1 and the pipe die 5 are connected is relatively far apart under the action of the reverse earthquake forces F1 and F2. At this time, through the translation of equipment in the convertor station, can drive the female 1 of pipe, with the fastener that female 1 of pipe is connected with equalizer ring assembly 2 moves to the F1 direction, female 5 of pipe, with the fastener that female 5 of pipe is connected with equalizer ring assembly 4 moves to the F2 direction. The length of the aluminum stranded wire on the horizontal distance can be increased to 2pi r1+2d1 (the length of the aluminum stranded wire and the initial form of the aluminum stranded wire during installation are assumed to be the same as those of specific extension data during specific implementation), namely the length of the aluminum stranded wire can be increased by 2pi r1+2d1-L1 to the maximum extent compared with the tensile length under the normal working condition under the earthquake working condition, and the requirements of horizontal relative displacement among devices under different earthquake working conditions can be met by adjusting the length of the aluminum stranded wire.
When an earthquake occurs, see fig. 4, the pipe nut 1 and the pipe nut 5 are relatively close, and the converter station equipment to which the pipe nut 1 and the pipe nut 5 are connected is relatively close under the action of the counter-acting forces F3 and F4. At this time, through the translation of the equipment of the converter station, can drive the female 1 of pipe, with the fastener that female 1 of pipe is connected with equalizer ring subassembly 2 moves to the F3 direction, female 5 of pipe, with the fastener that female 5 of pipe is connected with equalizer ring subassembly 4 moves to the F4 direction. As can be seen from fig. 4, the heights of the equalizing ring assembly 2 and the equalizing ring assembly 4 in the vertical direction are different, and are distributed in a staggered manner, and for the equalizing ring assembly 1, the distance between the upper first ring and the pipe nut 1 is d5, and the distance between the lower first ring and the pipe nut 1 is d4; for the equalizing ring assembly 4, the distance between the upper first circular ring and the pipe nut 5 is d4, and the distance between the lower first circular ring and the pipe nut 5 is d5; d3 is the height in the vertical direction of the first ring (where d3 < d4-d 5). Because d4 > d5+d3, when the equipment connected with the pipe nut 1 and the pipe nut 5 is relatively close under the earthquake working condition, the equalizing ring assembly 2 and the equalizing ring assembly 4 can be ensured not to be contacted, and the equalizing ring assembly 2 and the equalizing ring assembly 4 which are close to each other can not be damaged.
Under the earthquake working condition (the pipe nut 1 and the pipe nut 5 are relatively close), the length of the aluminum stranded wire can be compressed to L1-r2 on the horizontal distance (supposing data, the length of the aluminum stranded wire when specific compressed data is referenced to specific implementation and the initial form when the aluminum stranded wire is installed), wherein r2 is the outer radius of the second circular ring, namely the maximum stretchable length of the aluminum stranded wire can be reduced to r2 under the earthquake working condition relative to the normal working condition, and the horizontal relative displacement requirement between devices under different earthquake working conditions can be met by adjusting the length of the aluminum stranded wire.
According to the embodiment of the invention, flexible connection and displacement decoupling between devices are realized through the aluminum stranded wire hardware fitting, and the horizontal large displacement requirement between devices in a direct-current field under a high earthquake condition is met. The aluminum stranded wires provide enough displacement requirements for the connection between devices in the horizontal direction, so that outward stretching and inward compression can be realized; the equalizing ring components ensure that the electric fields of the joint connection parts are uniformly distributed, meet engineering requirements, and ensure that the equalizing ring components on the left side and the right side are not contacted when being mutually close in the horizontal direction; the wire clamp is used for fixing the aluminum stranded wire, and is connected with a pipe nut which is used for connecting different devices.
Compared with the prior art, the combined hardware fitting disclosed by the invention solves the problem that in the prior art, under the earthquake working condition, larger stress exists between two connecting ends and connected equipment, equipment is easy to damage or disconnect with corresponding equipment, so that the valve hall loses the basic electrical performance of the valve hall, the large relative displacement requirement among the equipment can be met, the flexible connection and displacement decoupling among the equipment are realized, and the converter station equipment is ensured not to lose the basic electrical performance of the converter station equipment.
While the foregoing is directed to the preferred embodiments of the present invention, it will be appreciated by those skilled in the art that changes and modifications may be made without departing from the principles of the invention, such changes and modifications are also intended to be within the scope of the invention.
