This design is specially carried out to ensure the safe production of desulfurization, denitration and dust removal systems in newly-built environment-friendly workshops and to ensure the reasonable distribution and transmission of electric energy.
This design mainly expounds the electrical design scheme for the step-down substation of the desulfurization, denitration and dust removal system in the newly-built environmental protection workshop. In the design, the load of desulfurization, denitration and dust removal system is calculated statistically and the transformer is selected. Design of main wiring scheme of substation; Calculation of short-circuit current; Selection and verification of primary equipment in substation; Selection of substation secondary circuit scheme and setting of relay protection; Design of lightning protection and grounding device for substation, etc.
