Embodiment Construction
[0024] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0025] A specific embodiment of a corona aging test device for an insulating sample of the present invention, as Figure 1 to Figure 8 As shown, it includes a first insulating board 1, a second insulating board 2 and an insulating base 3 arranged sequentially along the first direction, that is, the up and down direction. The columns 4 form the connection. The insulating base 3 is provided with a guide rail 5, and the guide rail 5 constitutes a moving structure. The guide rail 5 includes a first guide rail 5-1 and a second guide rail 5-2 arranged opposite to each other on the left and right. On the first insulating plate 1, the first electrode 11 is installed, the second insulating plate is equipped with the second electrode 12, and the second insulating plate 2 is provided with an insulating sample 13 corresponding to the position of the second electrod...

The invention relates to a corona ageing test device for an insulation sample. The test device comprises a first insulated plate with a first electrode and a second insulated plate with a second electrode, the second insulated plate is provided with sample placing position, the test device further comprises a movement structure, and the second insulated plate is assembled on the movement structureand includes first and second positions; in the first position, the first and second insulated plates are opposite to each other in a first direction, so that corona discharge between the first and second electrodes after electrification is applied to the insulation sample; and in the second position, the sample placing position of the second insulated plate is exposed out of the first insulatedplate in the first direction. The insulation sample to be tested is convenient to take and place in the second position, the test efficiency is improved greatly, it is not required to readjust a gap between the first and second electrodes under the same electrode gap requirement, and it is ensures that batch of insulation samples are tested in the same condition under the same electrode gap requirement.
Description
technical field [0001] The invention relates to a corona aging test device for insulating samples. Background technique [0002] Epoxy resin is often used as an insulating material for indoor low-voltage switchgear products. Although its short-term insulation resistance is excellent, its long-term insulation performance often suffers from electrical aging, heat generation, condensation, humidity, pollution and other environments. The impact of factors has been significantly reduced. Judging from the current experience of scholars at home and abroad on the performance of insulating materials for outdoor operating products such as composite insulators and porcelain insulators, electrical aging is considered to be one of the important factors that destroy the insulation resistance and life of materials. However, the current test devices for the research on the insulation resistance of epoxy resin materials are too simple, poor in precision, complicated to operate and single-pu...
