摘要: 为了深入研究储能用爆破板使用场景对其泄放效率的影响程度,搭建气体爆炸试验台,通过在1 m3压力容器中进行一系列的氢气点燃爆炸试验,探究不同氢气浓度对爆破板泄放效率的影响。试验结果表明:储能用爆破板装置本身存在一定的质量,打开时需要克服自身的惯性,因此泄放效率无法达到100%。同时氢气的浓度越高,爆破板的泄放效率越低。在氢气体积分数为13%、15%、19%、23%工况下的泄放效率分别为82.0%、72.9%、58.1%、51.9%。

Abstract: To investigate the impact of hydrogen concentration on the venting efficiency of explosion vent panels in energy storage applications, a gas explosion test bench was established. A series of hydrogen ignition experiments were conducted in a 1 m³ pressure vessel to evaluate venting performance under varying hydrogen volume fraction (13%, 15%, 19%, and 23%). The experimental results show that: The venting efficiency cannot achieve 100% due to the inherent mass of the vent panel, which requires overcoming inertial forces during activation. Venting efficiency exhibits an inverse correlation with hydrogen concentration, yielding values of 82.0%, 72.9%, 58.1%, and 51.9% for the tested concentrations, respectively.
