Embodiment 1

[0042] Such as figure 1 , figure 2 with image 3 As shown, the embodiment of the present invention provides a test platform for the research and development of electrical properties of insulating adhesives, including: high voltage generating equipment 10, test transformer oil tank equipment 20, oil treatment equipment 30 and oil storage tank 40; The high voltage generating equipment, the transformer oil tank equipment for testing, the oil treatment equipment and the oil storage tank are connected in sequence.

[0043] Among them, the high-voltage generating equipment is used to generate the high voltage for the test, that is, to simulate the high voltage generated in the actual operation of the transformer; the test transformer oil tank equipment, oil treatment equipment and oil storage tank are used to simulate the environment where the test product (that is, the insulating material) is located. The actual operating environment; among them, the transformer oil tank equipme...

Embodiment 2

[0078] Such as Figure 5 with Image 6 As shown, the embodiment of the present invention provides a test system for the research and development of the electrical properties of the insulating adhesive, including: a shielding device 500 and the test platform 600 for the research and development of the electrical properties of the insulating adhesive described in Embodiment 1, The test platform for the research and development of the electrical properties of the insulating adhesive is set in the shielding device.

[0079] Considering that the partial discharge monitoring of the test product is very sensitive, and the background of the conventional test environment is set at about 15PC, which cannot meet the monitoring requirements; therefore, a shielding device is set up in the entire test area to shield and isolate the external environment to ensure The detection is that the partial discharge signal only comes from the test object itself;

[0080] Specifically, the shielding ...

Abstract

The invention provides a test platform and system for research and development of the electrical performance of an insulating adhesive, and relates to the field of transformers. The test platform includes high voltage generating equipment, transformer oil tank equipment for testing, oil processing equipment and an oil storage tank, the high voltage generating equipment, the transformer oil tank equipment for testing, the oil processing equipment and the oil storage tank are connected successively, the transformer oil tank equipment for testing includes a high voltage sleeve and a transformer oil tank, the transformer oil tank is provided with a test electrode, one end of the high voltage sleeve is connected with the high voltage generating equipment, the test electrode includes a high voltage side electrode, a low voltage side electrode and an insulating material arranged between the high voltage side electrode and the low voltage side electrode, the insulating material includes a paperboard layer and an adhesive layer, the high voltage side electrode is connected with the other end of the high voltage sleeve, and low voltage side electrode is grounded. The problems that the development speed of the research and development field of the performances of transformer insulating material adhesives existing in the prior art is slow and research and development demands for the performances of insulating material adhesives of the transformer field cannot be met are solved, and improvement of the research and development efficiency of the electrical performance of the insulating adhesive is facilitated.

Description

technical field [0001] The invention relates to the field of transformer testing, in particular to a test platform and system for research and development of electrical properties of insulating adhesives. Background technique [0002] At present, the binders used in transformer laminated insulation products at home and abroad include: white glue, PVA, phenolic, casein, polyester resin and other categories. There are two ways to judge the actual use of various glues: 1. Use the previous design experience and refer to the historical requirements under the same voltage and capacity. 2. Sampling insulation material manufacturers, and confirming the entry threshold of adhesives through the sampling pass rate. [0003] The electrical stability of the internal insulating material is particularly important during the operation of the transformer, so many standard organizations at home and abroad have put forward specifications and requirements for the electrical performance of the ...
