Abstract
The invention discloses a lightweight equalizing ring for a test room. The lightweight equalizing ring comprises a ring body and is characterized in that the ring body is an annular core body which is made of a lightweight material and has a circular cross section; a layer of aluminum foil served as a conductive body is coated outside the core body; a copper tape is arranged at the inner circumference of the core body and is closely contacted with the aluminum foil; the copper tape is provided with more than two multi-core copper stranded wires served as conducting wires and fixing ropes; and the outer surfaces of the aluminum foil and the copper tape are provided with conductive films served as protective layers. The lightweight equalizing ring for the test room has the advantages that an equalizing effect similar to that of the conventional aluminum equalizing ring with the same dimension can be achieved; and the lightweight equalizing ring is made of materials such as plastic foam, the aluminum foil and the conductive films, so that the lightweight equalizing ring is low in cost, light in weight and convenient to assemble and fix.
Description
Technical field
The present invention relates to the grading ring of high-voltage testing equipment, specifically 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 to be installed on the different test specimens, and the connecting link that installation dimension is fixed is inapplicable, 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, and this class grading ring cost is high, heavy, it is rear yielding to be impacted.Because the test specimen of voltage levels is generally all very high, so this class grading ring is installed, fixing inconvenience.
Summary of the invention
The shortcoming of inconvenience is installed in order to overcome existing grading ring, the invention provides a kind of lightweight, 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 object of the invention 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 aluminium foil close contact; copper strips is provided with multicore copper stranded conductor more than two as wire 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 half of annular core element inner circle girth.
The invention has the beneficial effects as follows: can reach the close all pressures effect of unidimensional conventional aluminum grading ring, adopt the materials such as plastic foam, aluminium foil, conductive film, cost is low, lightweight, installation and convenient fixing.
Description of drawings
Fig. 1 is the cut-open view of grading ring of the present invention.
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 half of annular core element 3 inner circle girths 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 arrange flat copper band 1 and with aluminium foil 4 close contacts; 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 complete rear conductive film 5 ends.
Claims (4)
