3. Application in the intrinsically safe explosion protection system
In the intrinsically safe explosion protection system, the isolated safety barrier belongs to related equipment and is installed in a safe location
for connecting the intrinsically safe equipment in hazardous location and non-intrinsically safe equipment in safe location, which is capable
of limiting the energy entering into the site in safe value, so as to ensure the safety of site equipment, personnel and production.
The selection principles for the safety barrier in the intrinsically safe explosion protection system:
1) The grade of the explosion-proof marker of safety barrier must be not less than that of the intrinsically safe site equipment.
2) The port resistor and loop resistance of safety barrier should be taken into consideration so as to ensure the output voltage of safety
barrier can meet the requirements of the min. operating voltage of the intrinsically safe site equipment.
3) The safety parameters of the intrinsically safe port of safety barrier can meet:
Uo ≤ UI, Io ≤ Iin, Po ≤ Pin
Cc≤ Co-Ci, Lc ≤Lo-Li
4) Select the matched safety barrier according to the power supply polarity and signal type of intrinsically safe site equipment as well as its
transmission mode.
5) The wires leading to the dangerous places should use the blue safety wire, wire soft copper area must be greater than 0.5mm2,
dielectric strength should be greater than 500VDC.
