ፍቺ:
ከአጠቃላይ የኢንዱስትሪ እና የቤት ውስጥ የኤሌክትሪክ መሳሪያዎች ጋር ሲነጻጸር, ፍንዳታ-ተከላካይ የኤሌትሪክ መሳሪያዎች ፍንዳታ-ተከላካይ ዓይነት መሆናቸውን ለማመልከት አስፈላጊ ምልክቶች ሊኖራቸው ይገባል. ይህ የፍንዳታ መከላከያ ምልክት ተብሎ የሚጠራው ነው.
ዓላማ:
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 የሚቀጣጠል ጋዝ 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: ምሳሌ (Explosion-protect) represents “ፍንዳታ-ማስረጃ,” followed by the explosion-proof type (which can also include the equipment protection level), equipment category, explosion-proof grade symbol (ወይም የሙቀት መጠን), and/or equipment protection level symbol (ወይም የሙቀት መጠን).
The representations of the ፍንዳታ-ተከላካይ ዓይነት (መ, ሠ, እኔ, ገጽ, ኦ, ቅ, ኤም, n, ኤስ), equipment classification (አይ, II) (IIA, IIB, አይ.አይ.ሲ), temperature grading (ቲ1, T2, T3, T4, T5, T6), and equipment protection levels (Ca, Cb, ጋ; ማ, ሜቢ, ጂቢ) are well-established. ስለዚህ, we use these representations to exemplify the composition of explosion-proof markings for different types of ፍንዳታ-ተከላካይ የኤሌክትሪክ መሳሪያዎች.
