Abstract
The utility model discloses a vary voltage organ pipe end screen adapter device, including sleeve pipe conducting rod and lead -out wire slip ejector pin, lead -out wire slip ejector pin is close to the one end of sleeve pipe conducting rod pass through conductive spring with the sleeve pipe conducting rod is connected, and the other end is equipped with takes the screwed groove connection mouth, the sleeve pipe conducting rod lead -out wire slip ejector pin with conductive spring sets up with one heart. The utility model provides a vary voltage organ pipe end screen adapter device, the influence that can avoid the last difference of shielding the adapter dynamics of constructor fastening to bring, the phenomenon is thrown off in the connection of avoiding the long -time operation of equipment to lead to.
Description
Technical field
This utility model relates to matched transformer set field, particularly relates to a kind of transformer tube end shield adapter apparatus.
Background technology
Sleeve pipe is that inside transformer high and low pressure is guided to the insulated sleeve outside fuel tank, is the important component part of power transformer.It serves not only as lead-in wire insulation against ground, and is responsible for the effect of anchor leg, is one of transformator current carrying element.Sleeve pipe must possess enough electricapparatus intensity and heat stability, it is ensured that can be in operation bear permanent load electric current and short circuit time instantaneous overheated.If bushing shell for transformer existing defects or break down, will directly jeopardize safe operation and the power supply reliability of transformator.State evaluation currently for transformator works achieved with bigger progress, patrols and examines, electrical test, the means such as oil chromatogram analysis are it appeared that most of incipient fault in transformator running.
For transformator, sleeve pipe state of insulation and on-load voltage regulating switch mechanical performance are two blind areas of current on-line monitoring.Power transmission and transformation equipment state amount optimization analysis and research are implemented it is shown that the blind check rate of non-for transformator interruption maintenance strategy can be reduced by the enforcement of sleeve pipe dielectric loss and capacitance live detection from transformer station.Therefore carry out the research of power transformer sleeve pipe on-line monitoring and can reduce transformator operation risk significantly, improve operation of power networks reliability, there is great engineer applied and be worth.
Existing on-line monitoring technique is mostly adopted Hard link to realize signal for the lead-out mode being obtained pulse signal by Transformer Bushing Tap and draws also ground connection simultaneously, there is a problem being difficult to avoid that in this lead-out mode, it is simply that require the difference of the dynamics that workmen fastens cause connecting deformation, member position deviation or contact unreliable.
Utility model content
Because the drawbacks described above of prior art, technical problem to be solved in the utility model is to provide a kind of transformer tube end shield adapter apparatus, workmen is avoided to fasten the impact that the difference of end shield adapter dynamics is brought, it is to avoid the connection that equipment long-play causes disengages phenomenon.
For achieving the above object, this utility model provides a kind of transformer tube end shield adapter apparatus, including sleeved conducting rod and lead-out wire sliding mandril, described lead-out wire sliding mandril is connected with described sleeved conducting rod by power spring near one end of described sleeved conducting rod, the other end is provided with threaded groove connector, and described sleeved conducting rod, described lead-out wire sliding mandril and described power spring are arranged concentrically.
Will not both slip off to keep coaxial with spring energy compact siro spinning technology, it is preferable that described lead-out wire sliding mandril is curved protrusion near one end of described sleeved conducting rod.
This utility model has the advantages that
This utility model arranges power spring between conducting rod and lead-in wire push rod, there is certain extendable room between the two, but not it is completely fixed dead, when stem passes through screw threads for fastening with lead-in wire push rod, owing to the difference of workmen's dynamics cause connecting deformation, member position deviation or contacts unreliable, the connection that equipment long-play causes will not be avoided simultaneously and disengages phenomenon.
Below with reference to accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is described further, to be fully understood from the purpose of this utility model, feature and effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of a preferred embodiment of the present utility model；
1 is casing pipe protection shell, and 2 is sleeved conducting rod, and 3 is lead-out wire sliding mandril, and 4 is power spring, and 5 is sleeve pipe insulating core.
Detailed description of the invention
nullAs shown in Figure 1，A kind of transformer tube end shield adapter apparatus，Including casing pipe protection shell 1，Casing pipe protection shell 1 one end arranges sleeve pipe water joint，The detachable setting of casing pipe protection shell 1，Sleeved conducting rod 2 and lead-out wire sliding mandril 3 it is provided with in shell，Sleeved conducting rod 2 is coated and fixed in the enclosure in fixed mount by sleeve pipe insulating core 5 part，Sleeve pipe insulating core 5 is stretched out in sleeved conducting rod 2 one end，Other end length leaves a part of space less than sleeve pipe insulating core 5 inside，Power spring 4 it is provided with in this space，Power spring 4 is concentric with sleeved conducting rod 2 to connect，Power spring 4 other end is concentric with the slidably lead-out wire sliding mandril 3 of setting to connect，Therefore，Lead-out wire sliding mandril 3 is connected with sleeved conducting rod 2 by power spring 4，I.e. sleeved conducting rod 2、Lead-out wire sliding mandril 3 and power spring 4 are arranged concentrically.Wherein lead-out wire sliding mandril 3 is near one end (one end namely offseted with the power spring) projection in curved surface of sleeved conducting rod 2, is provided with threaded groove connector at the other end, and the transfer of stem may be inserted into this connector and realizes screw threads for fastening.
Preferred embodiment of the present utility model described in detail above.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without creative work.Therefore, all technical staff in the art pass through the available technical scheme of logical analysis, reasoning, or a limited experiment on the basis of existing technology according to design of the present utility model, all should in the protection domain being defined in the patent claims.
