Fashewar Shenhai-Hujja
Ma'anarsa:
Idan aka kwatanta da na gabaɗaya masana'antu da kayan lantarki na cikin gida, Dole ne na'urorin lantarki masu hana fashewa su kasance suna da alamun da suka dace don nuna cewa nau'in fashewa ne. Wannan shine abin da ake kira alamar alamar fashewa.
Manufar:
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 iskar gas mai ƙonewa 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: Ex (Explosion-protect) represents “fashewa-hujja,” followed by the explosion-proof type (which can also include the equipment protection level), equipment category, explosion-proof grade symbol (ko zafin jiki), and/or equipment protection level symbol (ko zafin jiki).
The representations of the nau'in hana fashewa (d, e, i, p, o, q, m, n, s), equipment classification (I, 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. Don haka, we use these representations to exemplify the composition of explosion-proof markings for different types of na'urorin lantarki masu hana fashewa.
