Application in intrinsically safe explosion protection system In intrinsically safe explosion protection systems, isolating barrier belongs to affiliated device. It is installed at safe area, as a connection between intrinsically safe devices in the hazardous area and non-intrinsically safe devices in the safe area. By limiting the energy to a certain safe threshold, it ensures the safety of field devices and people. Selection guidelines for intrinsically safe explosion protection system 1. The explosion protection grade of the barrier must be not less than that of intrinsically safe explosion protection device in spot. 2. Take inconsideration of hazardous end output resistance and loop resistance make sure the barrier output voltage meets the minimum operation voltage requirem ent of intrinsically safe device in spot. 3. The safety parameters about intrinsically safe end meets: Uo ≤ UI, Io ≤ Iin, Po ≤ Pin Co ≥ Cin, Lo ≥ Lin 4. Select suitable safety barrier which matches the intrinsically safe device in spot according to the power polarity, signal type and transmission mode about the device. 5. Much more protection is required, which can avoid the influence of the leakage current generated by safety barrier on intrinsically safe device in spot. 6. The wires leading to dangerous field should be constrainted in blue intrinsically safe wires, and its copper cross-section should be more than 0.5mm 2; Insulation intensity should be more than 500VDC.
