摘要: 根据AP/CAP核电厂爆破阀的试验大纲，需要对爆破阀药筒驱动装置进行输出性能试验，为完成试验开发了专用试验装置。介绍了AP/CAP核电厂爆破阀药筒驱动装置输出性能试验的原理、方法以及试验装置的开发内容。开发的试验装置点燃爆破阀药筒驱动装置产生高温气体，通过采集装置内包容的气体压力数据、绘制并分析压力-时间曲线，对药筒驱动装置的输出性能进行评价，并针对不同类型与规格的药筒驱动装置分别进行了测试。结果证明，该试验装置适用于多型号规格的爆破阀药筒驱动装置的试验，且性能可靠、操作方便。Abstract: According to the test program of the squib valve in AP/CAP nuclear power plant, the output test of the pyrotechnic actuator of the squib valve is required, and a special test device is developed to complete the test. The principle and method of output test of the pyrotechnic actuator of the squib valve in AP/CAP nuclear power plant and the development content of test device are introduced. The developed test device ignites the pyrotechnic actuator of the squib valve to produce high temperature gas. By collecting the gas pressure data contained in the device and drawing and analyzing the pressure-time curve, the output of the pyrotechnic actuator is evaluated. Different types and specifications of pyrotechnic actuators are tested respectively. The results show that the test device is applicable to the test of the pyrotechnic actuator of the squib valve with multiple types and specifications, and its performance is reliable and operation is convenient.
