The specific requirements for explosion-proof electrical design are primarily based on the national explosion-proof standard GB/T 3836 series. Different explosion-proof types, such as flameproof, intrinsically safe, and positive pressure, each have corresponding design standards.
Explosion-proof Design: Refer to the relevant requirements of GB/T3836.1 (General Requirements) and GB/T3836.2 (Type "d" Explosion-proof).
Safety Increase Design: Refer to the requirements of GB/T3836.1 (General Requirements) and GB/T3836.3 (Safety Increase Type "e").
Intrinsically Safe Design: Refer to the relevant requirements of GB/T3836.1 (General Requirements) and GB/T3836.4 (Intrinsically Safe "i").
Positive Pressure Design: Refer to the relevant requirements of GB/T3836.1 (General Requirements) and GB/T3836.5 (Positive Pressure Type "p").
Additionally, the national explosion-proof standard GB/T 3836 series specifies clear design requirements for different explosion-proof zones and various explosive environments.
Design Type N: Refer to the requirements of GB/T3836.1 (General Requirements) and GB/T3836.8 (Type "N").
Casting Seal Design: Refer to the relevant requirements of GB/T3836.1 (General Requirements) and GB/T3836.9 (Casting Seal Type "m").
Dust-Proof Ignition-Proof Enclosure Design: Refer to the requirements of GB/T3836.1 (General Requirements) and GB/T3836.31 (Type "t").
In addition, the National Infringement Standard GB/T 3836 series specifies clear design requirements for different infringement areas and explosive environments.
We primarily refer to the EN 60079 and IEC 60079 series standards for international explosion-proof standards.
