    摘 要:探討了核電設(shè)備抗震能力鑒定試驗(yàn)基本過程及評價方法,試驗(yàn)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(yīng)譜量級的確定原則,確定鑒定結(jié)論的可接受性。針對目前抗震考核中電氣設(shè)備的安裝環(huán)境模擬存在不足之處,給出了改進(jìn)措施與方法。根據(jù)核電站不同電氣設(shè)備工作的復(fù)雜性和多樣性特點(diǎn),列出了幾種常用的電氣性能監(jiān)測電路原理圖,并給出了具體的電氣性能評價方法。
    關(guān)鍵詞:核電站;反應(yīng)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
