Specific embodiment
The invention will be further described in the following with reference to the drawings and specific embodiments, so that those skilled in the art can be with
It more fully understands the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention.
Embodiment one：
As shown in Figure 1, a kind of splice type vibration damping lead yoke applied to inside oil-immersed transformer, including being fixed on transformer
Upper clamp plate 11, the crossbeam 1 of lower clamp plate 11 and the longeron 2 for anchor leg, the both ends of the longeron 2 respectively with two horizontal strokes
Beam 1 connects, and the longeron 2 is connect by joinery and its construction with the crossbeam 1.
The yoke being spliced by joinery and its construction plays the role of buffering energy-absorbing to the vibration of transformer, draws in satisfaction
On the basis of line support function, the effect of vibration and noise reducing is realized.
On the other hand, in the prior art, lead 11 is clamped on the longeron 2, and the longeron 2 follows transformer to vibrate band
Dynamic lead 11 is swung, and therefore, the connector of lead 11 just carries larger power, so as to generate electric arc danger and cause lead 11 exhausted
The fatigue resistance of edge layer declines.In the present invention, the resistance to shock of joinery and its construction slows down the vibratory output of the longeron 2, therefore, can
With smoothly clamp leads 11, above-mentioned harm is avoided.
Embodiment two：
It is further improved on the basis of embodiment one, the tenon and tongue-and-groove in the joinery and its construction have the gap of setting, institute
It states in gap filled with the fluid sealant for having elasticity after curing.
According to the specification of currently used 180kVA transformers, the size in the gap is typically set at 2 ~ 4mm.Gap mistake
Small, fluid sealant is difficult to fill completely, and gap is excessive, and yoke intensity is difficult to meet requirement.The transformer of remaining specification, can root
Take the circumstances into consideration to set the size in the gap according to the specification of yoke.
Filled with the fluid sealant for having elasticity after curing in gap, the fastness of connection can be enhanced, simultaneously as after curing
Have elasticity, when vibrating stress, when the tenon is moved with Impact direction, the fluid sealant after the curing is squeezed, it is described
Tenon is hindered tenon to continue to move to, therefore, resistance to shock is more preferable by reversed extruding force.
The present invention an optional embodiment in, the fluid sealant can be one-component polyurethane sealant, advantage
That bonding force is big, bonding force every square centimeter up to more than 30KG, meanwhile, there is preferable elasticity after colloid curing.
Embodiment three：
As shown in Fig. 2, being further improved on the basis of embodiment one, the joinery and its construction of 1 end of crossbeam includes：Crossbeam is slided
Slot 101 is located at the crossbeam tenon 103 of 101 both sides of crosstic shoe and crossbeam tongue-and-groove 102 respectively；The joinery and its construction packet of the longeron 2
It includes：Longeron sliding slot 201 is located at the longeron tenon 203 of 201 both sides of longeron sliding slot and longeron tongue-and-groove 202 respectively；The crossbeam tenon
103 coordinate with longeron tongue-and-groove 202, the crossbeam tongue-and-groove 102 coordinates with longeron tenon 203, as shown in figure 3, the crosstic shoe
101 form the chute hole 15 for being embedded in wedge block 3 with longeron sliding slot 201.
Wherein, the cross sectional shape of the crossbeam tenon 103 and longeron tenon 203 be not limited to circle shown in Fig. 2 or
Other shapes, such as triangle, rectangle, ellipse or other geometries.
In the present embodiment, crossbeam 1 and longeron 2 are both provided with tenon and tongue-and-groove, and joinery and its construction at two is formed after assembling, with reference to
It is more firm.
The crossbeam 1 is identical with 2 end construction of longeron, processing easy to produce.
More preferably, tenon and tongue-and-groove set certain gap, have elastic sealing after curing is filled in the gap
Glue.It is more excellent to connect more firm and damping property.
One optional embodiment of the present embodiment is that 3 material of wedge block is timber, and after wedging, yoke is more steady
Gu.
Another optional embodiment of the present embodiment is that 3 material of wedge block is rubber, is ensureing yoke stability
Meanwhile it improves damping.
Example IV：
As shown in figure 4, being further improved on the basis of embodiment three, secondary tenon is additionally provided at two on the outside of the joinery and its construction
Fourth of the twelve Earthly Branches structure, the pair joinery and its construction are intermeshed for the crossbeam 1 with longeron 2.
As shown in figure 5, in the present embodiment, the cross sectional shape of crossbeam tenon 103 and longeron tenon 203 is rectangle, accordingly,
Crossbeam tongue-and-groove 102 and longeron tongue-and-groove 202 are rectangular groove structure.
Secondary joinery and its construction, longeron are provided on the outside of the joinery and its construction that crossbeam tenon 103 and longeron tongue-and-groove 202 cooperatively form
It is provided with mutually isostructural secondary joinery and its construction on the outside of the joinery and its construction that tenon 203 is cooperatively formed with crossbeam tongue-and-groove 102, pair at two
Joinery and its construction is identical, only to be described at one.
The pair joinery and its construction includes：The crossbeam pair tenon 104 of multiple equidistant arrangements and corresponding longeron pair tongue-and-groove
204；The two is intermeshed, and limits degree of freedom of the crossbeam 1 in its length extending direction.Another two coordinate in its three dimensions
The joinery and its construction and wedge block 3 that the degree of freedom in direction is formed by crossbeam tenon 103 and longeron tongue-and-groove 202 limit.
In this scheme, multiple crossbeam pair tenons 104 and longeron pair tongue-and-groove 204 are intermeshed, and effectively improve the steady of yoke
It is qualitative.
Embodiment five：
In above-described embodiment, the crossbeam 1 respectively includes multiple portions with longeron 2, is connected between each section by joinery and its construction.
Other than being connected between the crossbeam 1 and longeron 2 by joinery and its construction, individual crossbeam 1 or longeron 2 also pass through tenon
Fourth of the twelve Earthly Branches structures to form forms, and for integrally-built crossbeam 1 or longeron 2, further enhances the damping of yoke, reduces
The vibratory output of inside transformer.
Lead yoke in the present invention is assembled by splicing, insulation performance is good, high temperature resistant, anti-corrosion capability are strong,
High mechanical strength and has certain elasticity.Splicing part is contacted, and utilize by groove with the engaged of protrusion
Wedge block is reinforced, and reaches the requirement of mechanical strength of down-lead bracket, while the non-rigid connection of splicing part, to transformer wire
Buffering energy-absorbing is played the role of in the vibration of circle, so as on the basis of leads support function is met, realize certain vibration and noise reducing
Effect.On the other hand, leading wire joint is avoided electric arc danger occurs and the fatigue resistance of lead wire insulation layer is caused to decline.This
Outside, yoke can carry out assembled according to the transformer demand of different volumes specification, simple and safe.
Embodiment described above is only to absolutely prove preferred embodiment that is of the invention and being lifted, protection model of the invention
It encloses without being limited thereto.The equivalent substitute or transformation that those skilled in the art are made on the basis of the present invention, in the present invention
Protection domain within.Protection scope of the present invention is subject to claims.
