摘要
目前,我国煤井所采用的开关器件大多为交流接触器,动作时容易产生火花,瓦斯遇到电气火花具有爆炸的可能,会直接威胁到矿井和工人们的生命安全。为了解决这一问题,使用无触点电气开关取代有触点的各类接触器是避免电气火花的有力措施。
At present,AC contactors are mostly used in the switching devices in coal mine in China,when movements,it is easy to generate sparks.Gas is met with electrical spark may cause the explosion,which direct threat to mine and the life safety of workers.In order to solve this problem,non-contact electrical switch is used to replace various types of contactors,which is an effective measure to avoid electrical sparks.
