| 摘 要： | This paper deals with the experimental study on the correlation between partial discharge （PD） characteristic parameters and corresponding aging degree of insulation in the course of the aging within eros,s-linked polyethylene （XLPE） insulation. The aging tests were performed on a section of 10 kV transmission cable by means of water needle method. The PD macroscopic characteristic parameters were found to be significantly dependent on the corresponding aging degree of insulation in the course of aging of XLPE, and different kind of aging stage has different characteristics. Beside, there are similar regularity but different PD amplitude in the course of aging of XI.PE insulation in different electrolyte, and their insulation life is different. Therefore, according to the chan ging regularity of the PD macroscopic characteristic parame ters within XLPE insulation judging the aging degree of XLPE insulation will be an effective method.

| Abstract: | This paper deals with the experimental study on the correlation between partial discharge (PD) characteristic parameters and corresponding aging degree of insulation in the course of the aging within cross-linked polyethylene (XLPE) insulation. The aging tests were performed on a section of 10 kV transmission cable by means of water needle method. The PD macroscopic characteristic parameters were found to be significantly dependent on the corresponding aging degree of insulation in the course of aging of XLPE, and different kind of aging stage has different characteristics. Beside, there are similar regularity but different PD amplitude in the course of aging of XLPE insulation in different electrolyte, and their insulation life is different. Therefore, according to the changing regularity of the PD macroscopic characteristic parameters within XLPE insulation judging the aging degree of XLPE insulation will be an effective method. |
