详细介绍: M2JA铸铁全封闭隔爆型三相异步电动机
在危险性区域内,正确使用防爆电气装置是极其重要的。为此,很多国家都对防爆电气装置的结构与用法作出了规定。GB 3836~2000爆炸性气体环境用电气设备的标准等效采用IEC60079,但高于IEC60079标准,根据我国的具体情况,在IEC60079基础上加上我国原标准的几个关键点,形成了GB 3836防爆标准的新特点。
M2JA系列(80~355)隔爆型电动机是上海ABB电机有限公司引进ABB公司21世纪最新隔爆型电动机的制造技术,结合中国GB 3836-2000标准的特点而开发的、目前国内最先进的工厂用4级隔爆电动机(Ex d llc)产品(温度组别T1~T4)。
Preamble
It is of vital importance to have a safe operation for electrical apparatus in hazardous zones. Therefore,many countries have set up rules for the design and operation of this specific apparatus. GB 3836-2000 is a set of Chinese standards for electrical apparatus in explosive gas zones. It is equivalent to IEC60079, but more demanding than IEC60079. The Chinese standards keep key points of its former version on the basis of IEC60079.
The R & D of M2JA series (80-355) flameproof motors is compatible with ABB's latest manufacturing technology and Chinese standards GB 3836-2000. The series can be credited with the most advanced flameproof motors (Ex d llC) for factory application in China (temperature class T1-T4).
