Abstract
The utility model discloses a lightweight grading ring used in a test room, including a ring body. The lightweight grading ring is characterized in that the ring body is a ringed core body which is prepared from a lightweight material and has a circular cross section. The core body is coated with a layer of aluminium foil used as an electric conductor, and the inside circumference is provided with a copper strip which tightly contacts with the aluminium foil. The cooper strip is provided with more than two multicore copper stranded conductors used as wires and fixed ropes. The outside surface of the aluminium foil and the cooper strip is also provided with an electroconductive film used as a protective layer. the utility model has the following beneficial effects: a grading effect similar to that of a common aluminium grading ring of the same size can be achieved; and by the adoption of materials such as plastic foam, the aluminium foil, the electroconductive film and the like, the lightweight grading ring provided by the utility model requires low cost, is light in weight, and is convenient to install and fix.
Description
Technical field
The utility model relates to the grading ring of high-voltage testing equipment, specifically is a kind of light-duty grading ring that is applicable to testing laboratory.
Background technology
Grading ring generally comprises ring body and connecting link two parts.The grading ring that testing laboratory uses is owing to need be installed on the different test specimens, and it is inapplicable that installation dimension is fixedly coupled bar, so the grading ring that testing laboratory uses is general only with a ring body.At present, ring body generally adopts aluminium alloy or stainless steel material to process, this class grading ring cost height, heavy, the back that is impacted is yielding.Because the test specimen of voltage levels is generally all very high, so this class grading ring is installed, fixing inconvenience.
The utility model content
In order to overcome existing grading ring the shortcoming of inconvenience is installed, the utility model provide a kind of in light weight, cost is low, be applicable to the light-duty grading ring in laboratory, this grading ring is installed and convenient fixing, even ring body falls, also can not cause damage to testing crew and test specimen.
The technical scheme that realizes the utility model purpose is:
The light grading ring of a kind of testing laboratory; comprise ring body; unlike the prior art be: ring body is the annular core element of a round section of being made by lightweight material; be wrapped with one deck aluminium foil as electric conductor at this core body; inside circumference is provided with copper strips and closely contacts with aluminium foil; copper strips is provided with multicore copper stranded conductor more than two as lead and static line, also is provided with conductive film as protective seam at aluminium foil and copper strips outside surface.
Described lightweight material is plastic foam, air bag or plastic tube.
Described copper strips is the flat copper band.
Spacing between described two multicore copper stranded conductors is long half of annular core element inner periphery.
The beneficial effects of the utility model are: can reach the close all pressures effect of unidimensional conventional aluminum grading ring, adopt materials such as plastic foam, aluminium foil, conductive film, cost is low, in light weight, installation and convenient fixing.
Description of drawings
Fig. 1 is the cut-open view of the utility model grading ring.
Among the figure: 1. flat copper band 2. multicore copper stranded conductors 3. annular core elements 4. aluminium foils 5. conductive films.
Embodiment
With reference to Fig. 1, determine the size of ring body according to the height of trial voltage, make the annular core element 3 of a round section of foams plastic material; Lap wound one deck aluminium foil 4 on annular core element 3; Be long half of annular core element 3 inner peripherys in the spacing of a wide about 10mm-20mm, thick about 0.3mm-0.5mm, length 2, two multicore copper stranded conductors 2 of flat copper band 1 two multicore copper stranded conductors of weldering identical with annular core element 3 inner circumferential length; At lap wound annular core element 3 inside circumference of aluminium foil 4 flat copper band 1 be set and closely contact with aluminium foil 4; Again with conductive film 5 two layers of aluminium foil 4 and flat copper band 1 outer annular core element 3 tight lap wounds as protective seam and eliminate static, tighten aluminium foil 4 and flat copper band 1, be adjacent to adhesive tape around conductive film 5 ends, intact back.
Claims (4)
1. light-duty grading ring of testing laboratory; comprise ring body; it is characterized in that: ring body is the annular core element of the round section made by lightweight material; be wrapped with one deck aluminium foil as electric conductor at this core body; inside circumference is provided with copper strips and closely contacts with aluminium foil; copper strips is provided with multicore copper stranded conductor more than two as lead and static line, also is provided with conductive film as protective seam at aluminium foil and copper strips outside surface.
2. light-duty grading ring according to claim 1, it is characterized in that: described lightweight material is plastic foam, air bag or plastic tube.
3. light-duty grading ring according to claim 1 is characterized in that: the spacing between described two multicore copper stranded conductors is long half of annular core element inner periphery.
