Abstract
Experimental Study on the Influence of Defect Characteristics of XLPE Cable on the Initial Voltage of Electrical Tree Cross linked polyethylene (XLPE) has excellent electrical insulation performance. Cross linked polyethylene is widely used as the insulating material of 10 kV power cables. With the acceleration of urbanization, a large number of cable entry projects have started. XLPE cables are widely used in medium and low voltage power grids. However, due to the lax production process and other problems, some defects or impurities will inevitably appear in the cable insulation. These problems accelerate the deterioration of cable insulation and lead to the generation of electrical tree, which further leads to the overall Breakdown Failure of the cable. These problems greatly affect the power supply reliability of the whole transmission system. In view of the above problems, this paper carried out an experimental study on the influence of the defect characteristics of XLPE cable on the starting voltage of electrical tree. First, the test platform of needle electrode short cable is built. Then the growth law of electrical tree under different defects is simulated by using this test platform. This research work is of great significance for constructing the numerical model of XLPE cable defects and analyzing the mechanism of the influence of XLPE cable defect characteristics on the starting voltage of electrical tree.
