本體參數(shù)及間隙結(jié)構(gòu)對(duì)EGLA放電電壓影響的研究
[Abstract]:In order to ensure that the performance of the line arrester (EGLA) with outer air gap can better meet the requirements of line insulation coordination, it is the most important to master the discharge voltage parameters of the gap. It has become a key issue to study the relationship between gap discharge voltage and various influencing factors. The discharge voltage of EGLA is closely related to bulk capacitance and gap capacitance. The capacitance and voltage distribution of 35kV 110kVEGLA sample with different bulk parameters and different gap structures were calculated by ANSYS simulation. The power frequency and impulse discharge voltage of EGLA were experimentally studied under the corresponding configuration. The simulation results were compared with the experimental results. It is concluded that the discharge voltage of EGLA is mainly affected by the bulk parameters and gap equivalent capacitors, and the equivalent capacitance of the bulk parameters has a greater effect on the discharge voltage.
