本安型防爆仪表热点燃评价方法研究

摘要

针对本安型防爆仪表热点燃评价的难点,在分析传统热点燃评价方法的基础上,提出两种本安型防爆仪表热点燃评价新方法——线性内插法和改进的小元件评定法.最后,给出了本安型电气设备热点燃评定的快速流程.%Aiming at the difficulty in thermal ignition assessment of intrinsically-safe instruments,and based on analyzing traditional thermal ignition assessment,two novel methods-linear interpolation method and improved small component assessment method were proposed,including the fast workflow of thermal ignition assessment.
