| 中文摘要: |
| 压力变送器广泛应用于核电厂压力、液位、流速等工艺参数的测量.大部分安装在安全壳内的压力变送器均经过了设计基准事故的鉴定,但超设计基准事故高温环境对其的影响仍未知.本文采用鉴定曲线包络法及仿真技术对其在设计基准事故和超设计基准事故下的工作情况进行了分析,给出了上述工况高温环境对其的影响,并通过分析结论,对该仪表耐高温性能的改进方向提出了建议. |
| 英文摘要: |
| Pressure transmitters are widely used in measuring of process parameters in nuclear power plant.Most of the pressure transmitters located in containment vessel have passed the DBA qualification,but whether they could survive in high-temperature environment in DBDA is unknown.In this article,we made analysis about the characteristics of pressure transmitter,and used both envelope and simulation methods to study how temperature affects the transmitter in DBA and BDBA condition.At last,we gave some suggestions on way of improving the resistance to elevated temperature of transmitter according to the study. |
