Shenhai, odporen na eksplozije
Opredelitev:
V primerjavi s splošno industrijsko in gospodinjsko električno opremo, električne naprave, odporne proti eksploziji, morajo imeti potrebne oznake, ki označujejo, da so odporne proti eksploziji. To je tisto, kar imenujemo oznaka za zaščito pred eksplozijo.
Namen:
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 gorljiv plin environments and hazardous areas where it can be safely used. Clearly, this is crucial information.
Composition:
The composition of the explosion-proof marking and examples of such markings consist of the following English letter combinations: npr (Explosion-protect) represents “protieksplozijsko varen,” followed by the explosion-proof type (which can also include the equipment protection level), equipment category, explosion-proof grade symbol (oz temperatura), and/or equipment protection level symbol (oz temperatura).
The representations of the protieksplozijsko varen tip (d, e, i, str, o, q, m, n, s), equipment classification (jaz, 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. torej, we use these representations to exemplify the composition of explosion-proof markings for different types of električna oprema, odporna proti eksploziji.
