Division of explosive gas environment hazardous areas
Different countries and regions divide explosive hazardous areas according to their own standards. Our country divides explosive gas environments into zones, zones and zones based on the frequency and duration of the occurrence of explosive gas mixtures. (Consistent with the International Electrotechnical Commission)
An environment where explosive gas mixtures appear continuously or for a long time.
Area where explosive gas mixture may occur during normal operation.
The area is an environment where explosive gas mixtures are unlikely to occur during normal operation or where explosive gas mixtures will only exist for a short period of time even if they occur.
Zones generally only exist in internal gas spaces such as sealed containers and storage tanks. Zones rarely exist in the actual design process and most cases belong to zones.
Explosive electrical equipment is divided into two categories
Category I electrical equipment for underground coal mines
Category II electrical equipment used in places other than mines
Category electrical equipment is suitable for explosive The maximum test safety gap or minimum ignition current ratio of gas mixtures is divided into three categories: II, II and II and is divided into six groups according to their maximum surface temperature.
Explosive gas mixtures are grouped according to ignition temperature, see table.
Explosive gas mixtures are classified according to their maximum test safety gap or minimum ignition current ratio, see table.

Properties Under specified test conditions, the ratio of the minimum ignition current of explosive mixtures of gas and steam to the minimum ignition current of explosive mixtures of methane. China stipulates that gas and vapor hazardous substances are classified into Class II, Class II and Class II according to the minimum ignition current ratio. The minimum ignition current ratio is Class II, and the minimum ignition current ratio is Class II. For example, ethane, ethylene, and acetylene are Class II, Class II, and Class II hazardous substances respectively.
Installation, use and maintenance
﹒ Before installation, check whether the basic data listed on the nameplate of this product is consistent with the actual use conditions
