The substation is the core link in the transmission and distribution of electricity. Post-electrical equipment holds an important position in substations. They are not only numerous but also diverse, and are very likely to be damage in earthquakes. This paper takes the 500 kV voltage transformer as the research object, installs a new type of steel wire rope seismic isolation bearing on it, and compares and analyzes the response characteristics of the prototype structure and the seismic isolation structure under seismic action through the seismic simulation shaker test. The test results show that the fundamental frequency of the isolation structure has been significantly reduced compared with the prototype structure, confirming the effectiveness of the new wire rope seismic isolation support in reducing the seismic response of post-electrical equipment. Meanwhile, the seismic isolation structure shows high isolation efficiency in reducing acceleration and stress response, but the isolation effect for displacement response is relatively limited. Under strong seismic effects, the seismic isolation structure can effectively reduce the acceleration and stress response of the equipment, which reduces the risk of breakage of porcelain insulators of transformers due to vibration. At the same time, the seismic isolation bearings will not have significantly reduced the top displacement response of the equipment. Therefore, in the subsequent improvement of the new wire rope seismic isolation support, it is necessary to comprehensively consider the various responses caused by seismic forces to ensure the overall safety of the equipment.
