摘 要:探討了核電設備抗震能力鑒定試驗基本過程及評價方法,試驗采用的阻尼比通常采用白噪聲掃描或正弦掃描的方法測得,提出了阻尼比及地震反應譜量級的確定原則,確定鑒定結論的可接受性。針對目前抗震考核中電氣設備的安裝環境模擬存在不足之處,給出了改進措施與方法。根據核電站不同電氣設備工作的復雜性和多樣性特點,列出了幾種常用的電氣性能監測電路原理圖,并給出了具體的電氣性能評價方法。
關鍵詞:核電站;反應譜;地震波;抗震能力鑒定;阻尼比

Abstract: This paper discussed the basic process and evaluation method of nuclear power equipment seismic capacity qualification test. The adopted damping ratio in the test could be obtained by white noise scanning or sinusoidal scanning.This paper proposed the certainty principle of damping ratio and earthquake response spectrum order and determined the acceptability of qualification conclusion.Aiming at the installation environment of electrical equipment in current aseismatic examination, this paper simulated the shortcomings and gave the improved measurements and methods.According to the complicated work and diverse characteristics of different electrical equipment in nuclear power plants, this paper listed the several kinds of common electrical performance monitoring circuit schematic and gave the specific evaluation methods for electrical performance.
Key words: nuclear power station; response spectrum; seismic wave; shock resistance appraisal; damping ratio
