摘要
分析了矿井隔爆型防爆电气设备隔爆外壳、隔爆面和引入装置等关键部件失效影响因素,提出失效判据和确定可靠性评估的考核指标,形成矿井防爆电气关键部件的安全可靠性评估方法。
Based on the analysis of the failure influencing factors of mine explosion-proof electrical key components explosion-proof shell,explosion-proof surface and interface components,the failure criterion is proposed,the assessment index of reliability evaluation is determined,and the safety and reliability evaluation method of mine explosion-proof electrical key components is established.
