Embodiment

[0025] The invention relates to a wrapping method for insulating paper used in aging tests. The insulating paper is wound on the copper conductor in the aging test device, and is mainly used to detect various properties of the insulating paper, such as the tensile strength of the insulating paper. A series of properties such as strength, tear strength, moisture content and breakdown voltage.

[0026] Such as figure 1 As shown, the above-mentioned aging test device includes an aging test device including a main tank body 1, a sealing cover 2, a copper conductor 3, some thermocouples 4, a temperature measuring probe, an aviation plug, some heating tubes 5 and some heating rods, due to heating The tube 5 cooperates with the heating rod, and the heating tube 5 is connected to the heating rod, so in figure 1 The specific label of the heating rod is not indicated in . In addition, when the aging test device is placed flat, there are corresponding air pipes and valves on the top an...

Abstract

The invention discloses an insulation paper wrapping method for an aging test. The method comprises the following steps that the insulation paper with different purposes can be classified, including insulation paper A used for heat insulation, insulation paper B used for testing tensile strength, insulation paper C used for testing the tearing strength, insulation paper D used for testing breakdown strength, and insulation paper E used for testing the moisture content. The insulation paper A is used for winding the whole M-shaped copper conductor; at least one insulation paper B is arranged onthe eight surfaces of the copper conductor of the M-shaped copper conductor respectively; at least two pieces of insulation paper E overlap with each other, and the whole copper conductor is wound bythe insulation paper E; at least two insulating paper C and an insulating paper D are respectively overlapped, and the copper conductors are vertically wound on each edge of the copper conductor in sequence; the whole M-shaped copper conductor is wound by using the insulation paper A. The insulation paper with different purposes is wound on the copper conductor according to a certain winding mode, and the performance of the insulation paper is detected, so that the detection data is more accurate and effective.

Description

technical field [0001] The invention relates to the technical field of aging experiments on insulating paper of transformers, in particular to an insulating paper wrapping method for aging experiments. Background technique [0002] Among power equipment products, one of the transformer products is insulating paper, and a series of performance tests need to be carried out on the insulating paper before it is used. In the prior art, the testing of insulating paper is simply placing it on the copper conductor in the aging test device, and there is no detailed wrapping method according to the various properties of the insulating paper that need to be tested. Contents of the invention [0003] In order to overcome the shortcomings and deficiencies of the prior art, the present invention provides a method for wrapping insulating paper used in aging tests, in which insulating papers for different purposes are wrapped on copper conductors according to their respective winding meth...
