تعریف:
در مقایسه با تجهیزات برق صنعتی عمومی و خانگی, دستگاه های الکتریکی ضد انفجار باید دارای علامت های لازم برای نشان دادن این باشد که از نوع ضد انفجار هستند. این همان چیزی است که از آن به عنوان علامت ضد انفجار یاد می شود.
هدف:
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 گاز قابل احتراق environments and hazardous areas where it can be safely used. واضح است, this is crucial information.
Composition:
The composition of the explosion-proof marking and examples of such markings consist of the following English letter combinations: سابق (Explosion-protect) represents “ضد انفجار,” followed by the explosion-proof type (which can also include the equipment protection level), equipment category, explosion-proof grade symbol (یا درجه حرارت), and/or equipment protection level symbol (یا درجه حرارت).
The representations of the نوع ضد انفجار (د, ه, من, پ, o, q, متر, n, س), equipment classification (من, II) (IIA, IIB, IIC), temperature grading (T1, T2, T3, T4, T5, T6), and equipment protection levels (Ca, Cb, Ga; مامان, Mb, گیگابایت) are well-established. بنابراین, we use these representations to exemplify the composition of explosion-proof markings for different types of تجهیزات الکتریکی ضد انفجار.
