摘　　要：核电站地震仪表系统须定期维护,进行通道检查、幅频响应测试等,以确保其能够正常运行;目前,国内用于核电站地震仪表系统维护、大修及检测的专用设备为开环结构,精度较低;结合地震仪表系统维护的现实要求,课题采用模块化设计思想,选用最新的电子技术成果,设计了一款闭环的、一体化的、便携式的核电站地震仪表系统检测装置;经实验验证,设备标定波形输出稳定,波形精度优于±5mV,在无外部电源的条件下,可正常运行5小时以上,各项指标均达到了实际应用的需要。The seismic instrument system of nuclear power plan must carry out regular maintenance, including channel check, the ampli tude and frequency response test, to ensure its normal operation. At present, the special equipment for maintenance used by domestic nucle ar power plant is openedloop structure and low accuracy. Combined with realistic requirements, using a modular design concept, selection of the latest electronic and technological achievements, this topic designed a closedloop, integrated, portable detection device of seismic in strumentation systems of nuclear power plant. Practice has proved that this device is practical and feasible. The waveform＇s accuracy is bet ter than ±4 5mV and can operate 5 hours without external power. It meets all the needs of oractieal application.
