Shenhai Explosion-Proof
definisi:
Dibandhingake karo peralatan listrik industri lan domestik umum, Piranti listrik sing tahan bledosan kudu duwe tandha sing dibutuhake kanggo nuduhake manawa piranti kasebut kalebu jinis tahan bledosan. Iki sing diarani minangka tandha bledosan.
tujuane:
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 gas sing bisa diobong environments and hazardous areas where it can be safely used. Cetha, 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 “bledosan-bukti,” followed by the explosion-proof type (which can also include the equipment protection level), equipment category, explosion-proof grade symbol (utawa suhu), and/or equipment protection level symbol (utawa suhu).
The representations of the jinis bledosan-bukti (d, e, i, p, o, q, m, n, s), equipment classification (aku, 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. Dadi, we use these representations to exemplify the composition of explosion-proof markings for different types of peralatan listrik bledosan-bukti.
