The issue of dual power supply in chemical enterprises
Thread Content
Which standard or government regulation requires dual power supply for chemical enterprises?
Dual-power supply for chemical enterprises is usually implemented in accordance with the \"Code for Fire Protection Design of Chemical Enterprises\" and/or relevant local regulations on power supply. .
GB50052 \"Code for Design of Power Supply and Distribution Systems\" 3.0.2 Class I loads shall be powered by dual power sources; in the event of a failure in one source, the other source shall not be damaged simultaneously.
For high-risk processes, dual power supply isn’t necessarily required, right?
It depends on the size of the primary power load; if it’s not large, a diesel generator can be used as well – it’s not necessary to have two circuits
Generally, it depends on the capacity of the primary and secondary loads, as well as the risk posed by power outages. Refer specifically to GB50052 \"Code for Design of Power Supply and Distribution Systems\".
