방폭표지판의 기능과 구성구조

정의:

일반 산업용, 가정용 전기기기 대비, 방폭형 전기 장치에는 방폭형임을 나타내는 데 필요한 표시가 있어야 합니다.. 이것을 방폭마킹이라고 합니다..

목적:

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 가연성 가스 environments and hazardous areas where it can be safely used. 분명히, this is crucial information.

Composition:

The composition of the explosion-proof marking and examples of such markings consist of the following English letter combinations: 전 (Explosion-protect) represents “폭발 방지,” followed by the explosion-proof type (which can also include the equipment protection level), equipment category, explosion-proof grade symbol (또는 온도), and/or equipment protection level symbol (또는 온도).

The representations of the 방폭형 (디, 이자형, 나, 피, 영형, 큐, 중, N, 에스), equipment classification (나, II) (IIA, IIB, IIC), temperature grading (T1, T2, T3, T4, T5, T6), and equipment protection levels (Ca, Cb, 가; 엄마, MB, Gb) are well-established. 그래서, we use these representations to exemplify the composition of explosion-proof markings for different types of 폭발 방지 전기 장비.
