10kV配电型氧化锌阀片工频小电流耐受特性的试验研究

EXPERIM ENTAL STUDY ON POWER FREQUENCY LOW CURRENT WITHSTANDING CHARACTERISTIC OF 10kV ZnO VARISTORS

试验研究了10kV配电型氧化锌阀片工频小电流(3～15mA)耐受特性,测试了几种典型工况下耐受电流、耐受时间与损坏特征,试验数据可供进行氧化锌避雷器监测或检修时参考。

Small current withstanding capacity test between3mA to15mA of10kV ZnO varistors is conducted in laboratory.A series of withstanding current and temperature characteristics are measured.The result is useful for insulation monitoring of10kV MOA.
