Description
Technical field
The utility model relates to a kind of grading ring, particularly relates to a kind of Existing during Partial Discharge Test for Transformer 110kV grade grading ring.
Background technology
The main product of current our unit is the power transformer of 110kV grade, and partial discharge test is the routine test of this grade product.The non-uniform electric field that in Existing during Partial Discharge Test for Transformer process, terminal binding post wedge angle produces produces high-energy corona discharge, has a strong impact on test and carries out and the mensuration of test findings, must take shielding measure.Existing use be tub shielding cap, this structure is owing to being do not have erection support but directly cap rested high pressure line end, there is much rugged wedge angle in crown under the effect of binding post wedge angle, test effect is had an impact, even if all upgrade, the appearance of this phenomenon is also inevitable.Settle the matter once and for all if want, must be improved from structure.
Utility model content
The utility model mainly solves the deficiencies in the prior art, provides a kind of compact conformation, increases work efficiency and measuring accuracy, has the Existing during Partial Discharge Test for Transformer 110kV grade grading ring of high promotional value.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
A kind of Existing during Partial Discharge Test for Transformer 110kV grade grading ring, comprise upper ring and lower ring and mounting seat, the top of described mounting seat is provided with equally distributed upper connecting pipe, described pressed on ring is fixed by upper connecting pipe, the bottom of described mounting seat is provided with equally distributed lower connecting pipe, described lower ring is fixed by lower connecting pipe, binding post is provided with in described mounting seat, described binding post is connected with bare copper wire, described pressed on ring and lower ring are that the diameter of described pressed on ring is identical with the diameter of lower ring up and down to dividing.
As preferably, described upper connecting pipe and lower connecting pipe are outward-dipping distribution, and the material of described upper connecting pipe and lower connecting pipe is respectively aluminium alloy.
The ceiling voltage that analysis transformer test process mesohigh line end may reach is to design the loop pipe caliber of grading ring pressed on ring and lower ring, after all component welding, entirety carries out polishing grinding, the burr wedge angle of abatement apparatus, stops that grading ring itself occurs and produces non-uniform electric field.Consider in easy for installation and installation process and collide unavoidably, select the alloy material that quality is light.Holes on base coordinates with bushing apical grafting terminal standard, and install reliable and stable, equipotential bonding takes Redundancy Design, guarantees that binding post is reliably connected with grading ring.
This grading ring can not produce with terminal binding post interferes, and there will not be the familiar lacunas that the equal pressure cap of tub is similar.
It is light that this grading ring equal pressure cap compared with before-improvement has quality, easy for installation, dependable performance, the advantages such as good looking appearance
Therefore, Existing during Partial Discharge Test for Transformer 110kV grade grading ring of the present utility model, compact conformation, all presses effect outstanding.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: as shown in Figure 1, a kind of Existing during Partial Discharge Test for Transformer 110kV grade grading ring, comprise pressed on ring 1, lower ring 2 and mounting seat 3, the top of described mounting seat 3 is provided with equally distributed upper connecting pipe 4, described pressed on ring 1 is fixed by upper connecting pipe 4, the bottom of described mounting seat 3 is provided with equally distributed lower connecting pipe 5, described lower ring 2 is fixed by lower connecting pipe 5, binding post 6 is provided with in described mounting seat 3, described binding post 6 is connected with bare copper wire 7, described pressed on ring 1 and lower ring 2 are up and down to dividing, the diameter of described pressed on ring 1 is identical with the diameter of lower ring 2.
Described upper connecting pipe 4 and lower connecting pipe 5 are in outward-dipping distribution, and described upper connecting pipe 4 is respectively aluminium alloy with the material of lower connecting pipe 5.
