摘要
Purpose/Aim
Due to poor manufacturing process, installation defects and long-term bad operating conditions, high-voltage cable is easy to cause problems such as moisture and structural damage of high-voltage cable outer sheath. Under long-term operation, local defect points of high-voltage cable outer sheath will develop with time, resulting in the increase of defect points of high-voltage cable outer sheath, Thus, the failure of the outer sheath of high-voltage cable is formed, and the insulation is damaged to make the insulation fail in advance. Therefore, it is very necessary to measure the insulation level of the outer sheath of high-voltage cable for the operation and maintenance of high-voltage cable.
Experimental/Modeling methods
Due to poor manufacturing process, installation defects and long-term bad operating conditions, high-voltage cable is easy to cause problems such as moisture and structural damage of high-voltage cable outer sheath. Under long-term operation, local defect points of high-voltage cable outer sheath will develop with time, resulting in the increase of defect points of high-voltage cable outer sheath, Thus, the failure of the outer sheath of high-voltage cable is formed, and the insulation is damaged to make the insulation fail in advance. Therefore, it is very necessary to measure the insulation level of the outer sheath of high-voltage cable for the operation and maintenance of high-voltage cable.
Results/discussion
The simulation and experimental results show that this method can effectively measure the insulation resistance of the outer sheath of high voltage cable in a certain range.
Conclusions
The on-line measurement of insulation resistance of outer sheath of high-voltage cable proposed in this paper provides a new method for on-line monitoring of high-voltage cable line.
