一、前言氢与空气或氧气形成的爆炸性混合物,遇有电火花、静电火花及危险温度等,就会引起燃烧或爆炸。而电气设备本身往往就是一个点火源。因此,在能够形成氢危险混合物的场所,不宜采用普通的电工产品,而应根据环境条件采用适当的防爆电气设备,或采取其它防爆措施。 I. INTRODUCTION An explosive mixture of hydrogen and air or oxygen can cause burning or explosion in the event of sparks, static sparks and dangerous temperatures. The electrical equipment itself is often an ignition source. Therefore, it is not advisable to use ordinary electrical products where hydrogen dangerous mixture can be formed, but appropriate explosion-proof electrical equipment or other explosion-proof measures should be adopted according to the environmental conditions.
