Description
Technical field
The present invention relates to electrode insulation testing field, specifically a kind of short sample Hi-pot test Electrode treatment of large scale superconducting magnet
Method.
Background technology
Thermonuclear fusion will provide inexhaustible clean energy resource, International Thermonuclear test reactor for the mankind（ITER）Plan will
It will be built up within 10 years futures.Its critical component is superconducting magnet, and the performance of superconducting magnet has decided on whether that required bit-type can be formed
Plasma.And superconducting magnet is difficult to repair and replace after on fusion facility once going wrong,
Therefore it needs to carry out a series of stringent tests to superconducting magnet before the mounting, wherein Hi-pot test is one of electrical testing
Point.Hi-pot test electrical breakdown occurs mainly in the end of test sample, it is therefore desirable to carry out special place to the end of test sample
Reason, so that the stress levels of end are higher than the class requirement of Hi-pot test.
Invention content the object of the present invention is to provide a kind of short sample Hi-pot test Electrode treatment method of large scale superconducting magnet,
This method can be realized carries out Hi-pot test to the short sample of superconducting magnet, comments the insulating structure design verification of superconducting magnet and performance
Estimate with highly important practical meaning in engineering.
In order to achieve the above object, the technical solution adopted in the present invention is：
A kind of short sample Hi-pot test Electrode treatment method of large scale superconducting magnet, it is characterised in that：First outside every conductor conduit
Insulating materials to be tested is wound respectively, more conductor conduits is constituted into conductor conduit array by array way arrangement, more are led
The central axis of body canal is mutually parallel, and test electrode is respectively welded in the end of every conductor conduit, and divides on test electrode
Insulating materials to be tested is not wound to carry out insulation processing；After insulation processing with G10 end caps be sleeved on test electrode on realize it is close
It seals and is filled with Teflon block；Then restraining is wound again outside conductor conduit array to be tied up；After finally tying up
Conductor conduit array by vacuum pressure impregnation carry out curing process obtain test sample.
A kind of short sample Hi-pot test Electrode treatment method of large scale superconducting magnet, it is characterised in that：The insulation
Material is combined by glass tape and polyamide tape, and tests the insulating materials on electrode and the insulation material outside conductor conduit
Expect that structure is identical.
A kind of short sample Hi-pot test Electrode treatment method of large scale superconducting magnet, it is characterised in that：The constraint
Band is glass tape material.
The present invention it is good convince body end head by patient analysis and prevent creeping discharge on the basis of, pass through the cured side of vacuum pressure impregnation
Formula forms groove wall insulating layer by the Teflon block of easy mold release between conductor end, and has in the end seals of conductor
G10 end caps prevent the discharging in advance between conductor end under high pressure to increase between end along face electrical breakdown distance, avoid pair
The interference that insulating layer calibration tape comes between conductor.
Description of the drawings

1) test electrode 4 is welded to the both ends of conductor conduit 3, weld seam is polished；
2) test electrode 4 is wound with insulating materials 6 to be tested；
3) G10 end caps 7 are passed through into test electrode 4, to seal the both ends of conductor conduit 3, and in the end of test electrode 4 and G10
One layer of glass fiber felt is placed between end cap 7；
4) test electrode 4, insulating materials 6 to be tested is passed through to be filled end Teflon block 5；
5) it carries out insulating materials to be tested to every conductor conduit 3 to wind, the winding number of plies and test 4 insulation processing phase of electrode
Together；
6) conductor conduit is subjected to array heap poststack, restraining 1 is wound outside conductor conduit array to play the role of constraint, beam
Ligature 1 is glass tape；
7) curing process is carried out to exemplar by vacuum pressure impregnation mode；
8) Teflon block 5 is taken out after exemplar solidification, then can carries out Hi-pot test.
Present treatment method for testing has carried out 90kV Hi-pot tests on small sample, disclosure satisfy that requirement.
