Abstract
This paper focuses on the insulation aging of high voltage cable, first summarizes the definition, characteristics and main manifestations of the insulation aging of high voltage cable, and clarifies its important influence on the safe and stable operation of the power system. Then, this paper analyzes the necessity of the detection of high-voltage cable insulation aging, and points out its significance for ensuring the safety of power system, extending the service life of cables and promoting technological innovation and industry development. On this basis, the causes of insulation aging of high voltage cable are deeply discussed, including uneven design of insulation layer thickness, design defect of shielding layer, improper material selection and uneven electric field distribution. Finally, for these reasons, put forward the corresponding optimization countermeasures, such as accurate calculation of insulation layer thickness, perfect the shielding design, strict selection standard and optimize the electric field distribution design, etc., aims to effectively delay the high voltage cable insulation aging process, improve the cable operation reliability, for the safe and stable operation of the power system to provide strong support. This study has certain theoretical value and practical significance for solving the insulation aging problem of high voltage cable.
