安全火花型电气设备,作为煤矿防爆电气设备的一种型式,在我国大约是在1958年开始的,当时主要是由抚顺煤炭科学研究所进行的。而在1960年以后,才推广应用于其它一般工业企业中。尽管作为一种防爆型式已经使用,但是鉴定安全火花型电气设备的标准,在最初还没有一个统一的国家标准.当时使用的试验装置,主要是采用两根互相垂直叠放的导线断开的方法产生的火花进行试验。通过试验决定电气设备是否属于安全火花型。这种试验装置被称为跳离式火花试验装置。1958年前后,又加工完成了拉断式
Safety spark-type electrical equipment, as a type of explosion-proof electrical equipment in coal mines in our country started in about 1958, mainly by the Fushun Coal Research Institute. After 1960, it was applied to other general industrial enterprises. Although it has been used as a type of explosion protection, there was not yet a single national standard for the identification of safe spark-type electrical equipment, and the test equipment used at that time was mainly a method of disconnecting two wires stacked vertically on top of each other The resulting spark is tested. The test determines whether the electrical equipment is a safe spark. This test device is called a jumper spark test device. Before and after 1958, but also completed the pull-off type
