Explosion proof rating statement

Explosion proof equipment definition: Electrical equipment that will not cause ignition in the surrounding explosive environment under specified conditions.

divided into three categories

Class I: Electrical equipment underground in coal mines;

Class II: Electrical equipment used in explosive gas environments other than coal mines and underground mines.

Class II can be divided into Class IIA, Class IIB, and Class IIC. Equipment marked as Class IIB can be used under the conditions of Class IIA equipment; IIC is applicable to the usage conditions of IIA and IIB.

Class III: Electrical equipment in explosive dust environments other than coal mines.

Class IIIA: Flammable flying fluff; Class IIIB: non-conductive dust; Class IIIC: Conductive dust.

Surface temperature: The temperature reached by any component of electrical equipment that may ignite the surrounding explosive environment when operating under adverse operating conditions within a specified range.The surface temperature should be lower than the flammable temperature.

For example, if the ignition temperature of explosive gas in an explosion-proof sensor environment is 100 ℃, then the sensoranyIn its working state, any component of itThe surface temperature should be below 100 ℃.

Temperature group

Electrical equipment used in explosive environments shall be in accordance with its specificationsSurface temperature is divided into T1-T6 groups
