Division of hazardous areas of explosive gas environments
Different countries and regions divide explosive hazardous areas according to their own standards. In our country, according to the frequency and duration of the occurrence of explosive gas mixtures , the explosive gas environment is divided into zones and zones. (Consistent with the International Electrotechnical Commission
Zones are environments where explosive gas mixtures appear continuously or for a long time.
Zones are environments where explosive gas mixtures may appear during normal operation.
Zone is an environment in which explosive gas mixtures are unlikely to occur during normal operation, or even if they occur, they will only exist for a short period of time.
Zones generally only exist inside sealed containers, storage tanks, etc. Gas space rarely exists in the actual design process, and most cases belong to the gas space.
Explosion-proof electrical equipment is divided into two categories
Class I electrical equipment for underground coal mines
Class II mine removal Electrical equipment used in other occasions
Class II electrical equipment is divided into three categories: II, IIB and II according to its maximum test safety gap or minimum ignition current ratio suitable for explosive gas mixtures and is divided into three categories according to its maximum surface temperature Six groups.
Explosive gas mixtures are grouped according to ignition temperature, see table.
Explosive gas mixtures are grouped according to their maximum test safety gap or minimum ignition current ratio (R classification, see table.

Properties: Under the specified test conditions, the ratio of the minimum ignition current of the gas vapor explosive mixture to the minimum ignition current of the methane explosive mixture. Chinese regulations Hazardous substances of gas vapor are divided into Class II [prohibited words], Class IIB and Class II according to the minimum ignition current ratio. The minimum ignition current ratio is Class II [Prohibited Word], and Class IIB is Class II. For example, ethane, vinyl, and acetylene They are Ⅱ[forbidden words], ⅡB level, and Ⅱ level hazardous substances.
