Shenhai Explosionssäker
Definition:
Jämfört med allmän elektrisk utrustning för industri och hushåll, explosionssäkra elektriska anordningar måste ha nödvändiga märkningar för att indikera att de är av explosionssäker typ. Detta är vad som kallas den explosionssäkra märkningen.
Ändamål:
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 brännbar gas environments and hazardous areas where it can be safely used. Tydligt, this is crucial information.
Composition:
The composition of the explosion-proof marking and examples of such markings consist of the following English letter combinations: Ex (Explosion-protect) represents ”explosionssäker,” 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 explosionssäker typ (d, e, i, sid, o, q, m, n, s), equipment classification (jag, 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 explosionssäker elektrisk utrustning.
