Abstract
The utility model discloses a sliding type damping connection device for a transformer substation and relates to the technical field of connection of tubular buses and electrical equipment for transformer substations. The sliding type damping connection device comprises a telescopic deformable arc line, an inner casing pipe and an outer casing pipe, wherein one end of the arc line is welded on the inner casing pipe; the other end of the arc line is welded on the outer casing pipe; one end of the inner casing pipe is connected with an external equipment terminal plate; the other end of the inner casing pipe extends into the outer casing pipe and can slide in the outer casing pipe; and the outer casing pipe is used for fixing the external tubular bus. The sliding type damping connection device has the advantages that in case of earthquake, earthquake energy can be dissipated by the sliding of the inner and outer casing pipes and the deformation of the arc line, so that the earthquake response of a lead is reduced, the interaction between the tubular bus and the electrical equipment is reduced and the earthquake resistance of the electrical equipment is improved.
Description
Technical field
The utility model relates to transformer station tube type bus and electric equipment jockey, specifically a kind of transformer station slidingtype damped junction device.
Background technology
The shape of electric equipment is elongated in the transformer station, and top porcelain tube quality connects by the soft or hard wire between the equipment greater than lower bracket.At tube type bus and electric equipment link position, be provided with inverse u shape temperature joint, this temperature joint has certain flexible ability, can adapt to the distortion of tube type bus because expanding with heat and contract with cold and producing, and reduces the temperature stress of tube type bus.But under geological process, larger relative displacement can occur between tube type bus and the electric equipment, the deformation adjustment ability of temperature joint so that the seismic response of wire can have influence on electric equipment, has increased the destruction probability of electric equipment head and shoulders above.Therefore, in the urgent need to studying a kind of device that in earthquake, can effectively reduce wire and electric equipment interaction.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the utility model provides a kind of transformer station slidingtype damped junction device, can reduce the interaction between tube type bus and the electric equipment during earthquake.
The utility model is realized with following technical scheme: a kind of transformer station slidingtype damped junction device, comprise flexible curved line, inner sleeve and outer tube, and curved line one end is welded on the inner sleeve, and the other end is welded on the outer tube; One end of inner sleeve is used for connecting outside equipment end daughter board, and the other end other end stretches into outer tube and can slide in outer tube, and outer tube is used for the tube type bus of fixed outer.
The beneficial effects of the utility model are: when earthquake occurs, the slip of internal and external casing and the distortion of the curved line seismic energy that can dissipate, reduce the seismic response of wire, reduced the interaction between tube type bus and the electric equipment, improved the shock resistance of electric equipment; This device can satisfy the requirement of tube type bus temperature deformation simultaneously, and being specially adapted to fortification intensity is in the transformer station in 8 degree and above area.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model mounting structure schematic diagram.
Among the figure: 1, curved line, 2, inner sleeve, 3, outer tube, 4, connecting plate, 5, the end-blocking plate, 6, sliding bearing, 7, the equipment end daughter board, 8, tube type bus.
Embodiment
As shown in Figure 1, a kind of transformer station mainly comprises inner sleeve 2 and the outer tube 3 that is connected by curved line 1 with the slidingtype damped junction device.One end of curved line 1 is fixed on the inner sleeve 2, and the other end is fixed on the outer tube 3.Curved line 1 is aluminium stranded conductor, adopts between curved line 1 and inner sleeve 2 and the outer tube 3 to be welded and fixed together.
In order to realize that inner sleeve 2 can slide in outer tube 3, inner sleeve 2 is aluminum alloy materials, and its end cover that stretches into outer tube 3 has sliding bearing 6, contacts with its inwall by sliding bearing 6.
In order to make things convenient for fixedly tube type bus of outer tube 3, outer tube 3 is aluminum alloy materials, by up and down two form, be bolted and be integral body, and lock ring tube type bus 8.Outer tube 3 inwalls are smeared lubricant, are used for the friction between minimizing and the sliding bearing 6.Sliding bearing 6 adopts aluminum alloy materials to make.
In order better to connect outside equipment end daughter board 7, sleeve pipe 2 one ends link to each other with connecting plate 4 by end-blocking plate 5, have circular hole on the connecting plate 4, are bolted between connecting plate 4 and the equipment end daughter board 7.End-blocking plate 5 adopts aluminum alloy materials to make.
As shown in Figure 2, the slidingtype flexible damping device is installed between electric equipment and the tube type bus.Adopt this device to connect tube type bus and equipment end daughter board, can satisfy the during normal use requirement of temperature deformation of tube type bus, reduce the temperature stress of tube type bus.When earthquake occured, the internal and external casing quick sliding made curved line 1 alternately produce compression and stretcher strain, a large amount of seismic energies dissipate, reduce the seismic response of tube type bus, can significantly reduce tube type bus to the tractive effect of electric equipment, improve the shock resistance of outgoing line interval system.
