Shenhai eksplozyon-prèv
Dapre estanda nasyonal pou pwoteksyon eksplozyon elektrik, tou de BT4 ak BT6 tonbe anba Klas IIB.
| Gwoup Tanperati nan ekipman elektrik | Maksimòm tanperati sifas admisib nan ekipman elektrik (℃) | Tanperati ignisyon gaz/vapè (℃) | Nivo tanperati aparèy aplikab yo |
|---|---|---|---|
| T1 | 450 | > 450 | T1 ~ T6 |
| T2 | 300 | >300 | T2 ~ T6 |
| T3 | 200 | > 200 | T3 ~ T6 |
| T4 | 135 | >135 | T4 ~ T6 |
| T5 | 100 | >100 | T5 ~ T6 |
| T6 | 85 | >85 | T6 |
Sepandan, the ‘T’ classification pertains to the temperature rating of explosion-proof electrical devices. Aparèy ki klase kòm T6 dwe kenbe yon tanperati sifas ki pa pi wo pase 85 ° C, T5 pa dwe depase 100 ° C, and T4 must not surpass 135°C.
The lower a device’s maximum surface tanperati, the less likely it is to ignite atmospheric gases, thereby enhancing safety. Kontinwe, the explosion-proof rating of BT6 exceeds that of BT4.
