| Zusammenfassung: | The invention relates to a power distribution network 6kV cable aging state evaluation method based on multistage discharge coefficients. The method comprises steps of firstly, collecting partial discharge information of a 6kV cable of the power distribution network; then calculating the multi-stage discharge coefficient of the 6kV cable of the tested power distribution network; and finally, based on the multi-stage discharge coefficient, evaluating the aging state of the tested 6kV cable of the power distribution network, thereby providing a method for judging the aging state of the 6kV cable of the power distribution network. According to the method, the aging state of the 6kV cable of the power distribution network can be evaluated conveniently and quickly, and reference is provided for maintenance and replacement of the 6kV cable of the power distribution network.
