【摘要】：為了開展煤礦用非金屬材料抗靜電性能直接法檢測技術(shù)研究,建立一套靜電火花試驗(yàn)系統(tǒng),重點(diǎn)地研究分析典型環(huán)境因素(溫濕度、瓦斯?jié)舛取⑶蛐伍g隙)條件下靜電火花引燃瓦斯氣體(即甲烷-空氣混合氣體)所需的靜電電壓變化規(guī)律。結(jié)果表明:引燃瓦斯氣體所需靜電電壓隨著溫度的升高而持續(xù)降低;隨著濕度增加而增加。得出了此試驗(yàn)系統(tǒng)引燃瓦斯的敏感間隙在1.5~2 mm之間和敏感甲烷濃度為9.5%~10%,驗(yàn)證了試驗(yàn)系統(tǒng)的可靠性。
[Abstract]:In order to study the direct testing technology of antistatic property of nonmetallic materials used in coal mines, a set of electrostatic spark test system was established, and the typical environmental factors (temperature and humidity, gas concentration, gas concentration) were studied and analyzed emphatically. Under the condition of spherical gap), the change rule of electrostatic voltage required to ignite gas gas by electrostatic spark (that is, methane air mixture gas). The results show that the electrostatic voltage required for gas gas ignition decreases continuously with the increase of temperature. With the increase of humidity, the sensitive gap of ignition gas and the concentration of sensitive methane in this test system are found to be between 1.5 and 2 mm, respectively, and the sensitivity methane concentration is 9.510, which verifies the reliability of the test system.
