摘　　要：本文中作者以JKDK-405/220中性点接地电抗器为例,对抗震特性进行了计算分析,介绍了试验仪器和设备等试验情况,解析推导了不同运行工况下的各个测点的频率,并着重对各个测点的应变和安全系数进行了详细计算分析,为提高电抗器的抗震能力及产品的稳定运行提供技术保障。Taking the JKDK-405/220 neutral point grounding reactor as an example, the anti-seismic characteristics are calculated and analyzed, the test conditions such as test instruments and equipment are introduced, and the frequency of each measuring point under different operating conditions is analytically deduced. The strain and safety factor of each measuring point are calculated and analyzed in detail to provide technical support for improving the seismic capacity of the reactor and the stable operation of the product.
