- Abstract
Bushing dielectric loss factor measurement test is a very high sensitivity. Through the analysis of the measurement data, it can be judged whether the insulation of the equipment is the whole damp, the deterioration of the insulation, and the local defects of the small capacitor. Introduces the method of measuring wall bushing dielectric loss factor and judgment. Through the analysis of the reasons of casing collapse equipment, dielectric loss test of abnormal data of a 66kV substation C wall. Wall bushing is an important equipment widely used in power system, it is the role of the high voltage wires safely through the ground walls, which is connected with other equipment. Therefore, it has the function of insulation, but also has a mechanical fixed effect. Once the insulation is damaged, the operation of high voltage bushing may cause flashover and discharge, which may cause the breakdown of insulation, which will bring loss to the safe operation of power system. In the structure of the high voltage bushing, the absolute distance between the metal flange and the conductive rod is small, and the electric field intensity in the operation is large, and the insulation requirement is high, and the fault is easy to be out of order.
