Partial Discharge Test Hall
Background
With the improvement of the transformer voltage grade, factory design margin reducing, transformer partial discharge performance to cause the attention of most of the transformer manufacturers. But at present in China do not have insulation manufacturers have the ability to do discharge performance simulation test, even the vast majority of large transformer manufacturers do not have the ability to separate discharge performance of the test material.
Facing the domestic situation, in order to increase the performance of insulation materials manufacturing industry development depth, we are the first one to establish partial discharge test hall. Through the experiment of the hall further to understand insulation electrical performance charecteristics. In our laboratory we have the ability of insulation material of IEC, GB, JBT standard test (mechanical and electrical properties) and AC, HVDC simulation of partial discharge under transformer oil test.
Research Orientation
With the establishment of the partial discharge test hall, our company in addition to the conventional material performance verification, further research fluctuation characteristics of insulation performance, such as:
1.Insulation materials with different moisture on material will affect the electrical strength and the partial discharge.
2.Same material under the condition of different DP value, the influence of the electrical strength and the partial discharge on the material.
3.Compared the electrical strength in oil and air under the different density of insulation materials.
4.Electrical strength of transformer oil affects the combination of oil and paper insulation materials.
5.Appearance characteristic of insulation materials in oil leaders creepage and breakdown.
6.Different particles inside the insulation materials influence degree on the properties of insulation.
7.Hollow of insulation materials affect the performance of partial discharge.
8.Glue thickness of lamination materials affect the insulation performance.
