摘　　要：为获取户外高压隔离开关的动态特性、研究瓷瓶破断力与地震载荷的关系以及验证隔离开关的抗震性能,开展了相关的考核试验。依据IEEE 693-2005标准的要求,试验前进行了应变计的校准试验、瓷瓶的弯曲破断试验和隔离开关的抗震性能试验。经过抗震试验,隔离开关完好无损且在抗震试验前后其共振频率变化不大,瓷瓶破断力大于地震载荷的2倍。结果表明隔离开关结构稳定,通过了抗震考核。In order to obtain the dynamic characteristics of the outdoor high voltage disconnector and the relationship between the breaking force of the porcelain insulator and the earthquake load, and to verify the seismic performance of the disconnector, the calibration test of the strain gauge is carried out before the seismic test, the bending breaking test of the porcelain insulator is carried out on the basis of the requirements of the IEEE 693-2005 standard. Then the seismic performance test of the disconnector is conducted. After seismic testing, the disconnector is intact, and the resonance frequency of the porcelain insulator does not changed before and after the seismic test. The breaking force of the porcelain insulator is 2 times greater than that of the earthquake load. The result shows that the structure of the disconnector is stable to bear the seismic assessment.
