摘要
针对传统电抗器隔震消能装置,在低于设计震动强度时不能高效保护电抗器,而在高于设计震动强度时会造成电抗器不可避免的损坏问题。文中提出了一种新型的高压电抗器隔震消能装置的设计方案,该方案混合使用铅芯隔震基座、限位装置及防落装置,能更好地保护高压电抗器。为验证所设计装置的有效性,文中基于3种模拟波对地震环境进行仿真模拟,分析在地震环境中电抗器薄弱环节的应力加速度与位移。测试结果表明,该隔震消能装置在结构完备时可以良好的保护电抗器,即使在失效情况下也仍可起到一定的保护作用。
For the traditional reactor isolation and energy dissipation device,the reactor cannot be effectively protected when the vibration intensity is lower than the design,and the inevitable damage of the reactor is caused when the vibration intensity is higher than the design.In this paper,a new design scheme of high voltage reactor isolation and energy dissipation device is proposed.The solution uses a lead core isolation base,a limit device and a fall prevention device to better protect the high voltage reactor.In order to verify the effectiveness of the designed device,the seismic environment is simulated based on three kinds of simulated waves,and the stress acceleration and displacement of the weak link of the reactor in the seismic environment are analyzed.The test results show that the isolation and energy dissipation device When the structure is complete,the reactor can be well protected,and it can still play a certain protective role even in the case of failure.
