Shenhai eksplosjonssikker
Definisjon:
Compared to general industrial and domestic electrical equipment, explosion-proof electrical devices must have necessary markings to indicate that they are of an explosion-proof type. This is what is referred to as the explosion-proof marking.
Hensikt:
Each explosion-proof electrical device should have its explosion-proof marking clearly displayed on its visible parts and nameplate. This system provides essential information, indicating that the marked electrical equipment is explosion-proof and specifying the types of brennbar gass environments and hazardous areas where it can be safely used. Helt klart, this is crucial information.
Composition:
The composition of the explosion-proof marking and examples of such markings consist of the following English letter combinations: Eks (Explosion-protect) represents “eksplosjonssikker,” followed by the explosion-proof type (which can also include the equipment protection level), equipment category, explosion-proof grade symbol (eller temperatur), and/or equipment protection level symbol (eller temperatur).
The representations of the eksplosjonssikker type (d, e, jeg, s, o, q, m, n, s), equipment classification (Jeg, II) (IIA, IIB, IIC), temperature grading (T1, T2, T3, T4, T5, T6), and equipment protection levels (Ca, Cb, Ga; Ma, Mb, Gb) are well-established. Så, we use these representations to exemplify the composition of explosion-proof markings for different types of eksplosjonssikkert elektrisk utstyr.
