Description
Technical field
The present invention relates to a kind of insulation support bodies.It specifically, is for supporting dividing for the high voltage component in electron accelerator
Pressure type high-voltage insulation strut.
Background technique
It is both known about in electron accelerator manufacture and application field, under the high voltage component in electron accelerator high pressure generator
It is both provided with insulation column.Traditional insulation column is monoblock type, and this integral post is mostly organic glass, polysulfones or poly-
Carbonate articles.Monoblock type insulation column is the problem is that Potential distribution is uneven.Due to Potential distribution unevenness, it is in height for a long time
Under electric field, it is easy to radial breakdown or axial punch-through occur.For the anti-high-voltage breakdown intensity for improving insulation column, side is commonly used
While method is the height and diameter of increase insulation column, it is to be ensured that insulation column is sufficiently dry.Although increasing height can mention
The anti-high-voltage breakdown intensity of high insulation column, but limited by use space, it can be used only in the biggish occasion of use space, it can not
Used in the lesser occasion of use space.In addition, all containing in the nonmetallic materials of organic glass, polysulfones or polycarbonate article etc
There is certain moisture.Therefore, it needs often to carry out dehumidification work in use.It is not only more troublesome, and maintenance cost is high.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of partial pressure type high-voltage insulation struts.Using this insulation column, not only
It is not limited by use space, can also reduce maintenance cost.
The invention solves the above problem be realized by the following technical scheme:
Partial pressure type high-voltage insulation strut of the invention, including upper flange and lower flange, upper lower flange are metal product；Its feature
It is: has the identical short cylinder of insulation of at least two diameters between upper flange and lower flange, that insulation of upper flange and the top is short
There is welding piece between the adjacent short cylinder of insulation between cylinder, outside in the welding piece between upper flange and that short cylinder that insulate of the top
It is connected with the inner shield ring and external shield ring that cross section is ellipse respectively.Outside connects respectively in welding piece between the adjacent short cylinder of insulation
Having cross section is the interior potential dividing ring and outer potential dividing ring of ellipse.
Wherein: the upper flange, lower flange, inner shield ring, external shield ring, interior potential dividing ring and outer potential dividing ring are stainless steel
Product.The stainless steel is No. 304 stainless steels.
The short cylinder of insulation is aluminium oxide ceramic products.
The welding piece is 4J33 expansion alloy product.
Further improvement of the present invention scheme is that have annular protrusion and outer annular protrusion above the lower flange, inside and outside
There is middle annular protrusion between annular protrusion, inside-and-outside ring pipe protrusion is above middle annular protrusion, and middle annular protrusion and annular are convex
Rise has spacing between outer annular protrusion；The internal diameter and outer diameter of middle annular protrusion are identical as the internal-and external diameter of short cylinder that insulate respectively, most
The short cylinder lower end of the insulation of lower section is placed on middle annular protrusion by a welding piece.
As can be seen from the above scheme, due to having the identical short cylinder of insulation of at least two diameters, upper method between upper lower flange
There is welding piece between that blue and the top short cylinder that insulate between the adjacent short cylinder of insulation, that of upper flange and the top are absolutely
Outside is connected with the inner shield ring and external shield ring that cross section is ellipse respectively in welding piece between the short cylinder of edge.The adjacent short cylinder of insulation
Between welding piece in outside be connected with respectively cross section be ellipse interior potential dividing ring and outer potential dividing ring.It is divided into using by insulation column
The form of several segments keeps the current potential assigned on each section almost the same.Compared with traditional Integral high-pressure insulation column, avoid
Radially breakdown or axial punch-through occur caused by Potential distribution is uneven.Due to there is at least two diameters between upper lower flange
The identical short cylinder of insulation is constituted, and compared with the background art, identical high pressure, partial pressure type high-voltage insulation strut of the invention is isolated
The half that height only has monoblock type insulation column in background technique can be used in use space so that height of the invention is lower
Biggish occasion, and it can be used in the lesser occasion of use space, it is not limited by use space.In addition, since the insulation is short
Cylinder is aluminium oxide ceramic products, and this ceramics pass through high temperature sintering, internal moisture-free, and will not absorb in atmospheric environment
Moisture.Therefore, it is not required to carry out dehumidification work in use, not only uses more convenient, also reduce maintenance cost.
In another aspect, due to there is the identical short cylinder of insulation of at least two diameters between upper lower flange, so that the present invention is hollow structure.With
Traditional solid insulation pillar is compared, and weight is not only alleviated, it is thus also avoided that long-time service easily punctured under high electric field
It happens.
