Abstract：Seismic test is one of the important contents in the identification of low-voltage switchgear of grade 1E in nuclear power plant. Its purpose is to test the seismic performance of switchgear and the action of its functional components by vibration test on the simulated seismic test bench. Based on the first aseismic test results, the structure of low-voltage switchgear is analyzed, and the corresponding improvement scheme is put forward. The effectiveness of the structural improvement is verified by comparing the test results before and after the improvement. In order to improve the seismic performance of switchgear structure, a solution is provided.
