Chip varistor materials contain over-voltage protection device


Sub-mandrel at both ends of the glass fiber embedded within a thin metal electrodes: wire-side configuration within the electrode and grading ring. The tower side of the inner electrode configuration only received patent No. 200810151050.4 f). f2) inner electrode and grading ring configuration when the composite insulator. Side of the inner electrode wires, fittings and grading ring formed between the low electric field areas, reducing the commitment of the part of the potential distribution in the insulating side of the tower. Side of the electrode and pole fittings and other potential,[link widoczny dla zalogowanych], stretching from the electrodes, covered with insulation in the tower side of the gold electrode with the formation of the axial low electric field area. Reduce the commitment of the part of the insulating potential: the formation of the electrode tip and below the high electric field. Uplift of the inner part below the electrode tip insulation voltage f31 assumed simulation and experiment results show that, within the electrode and grading ring configuration method can effectively increase the mean pressure equalizing device, shielding and conductivity arc effect. Suppression of corona discharge and electrical insulator erosion. And to achieve composite insulator electric field distribution of electric field and the greatest degree of uniformity. And the method has advantages of saving metal resources, reduce the workload of other advantages f41-site installation ends with a long composite insulator jacket, umbrella fittings to the most recent to bear a higher potential drop skirt, which easily lead to erosion of the department power. Lead to loss of outer insulation, after the fracture of FRP rod insulator erosion potential and electric field distribution in the region to consider the impact and effectiveness.
