Can a power distribution room be installed in a Class A factory building?
Thread Content
With reference to the specifications for fine chemicals, point 5 of section 8.3.1, I would like to ask the experts whether it is possible to install distribution rooms (containing high and low voltage transformers) on the second and third floors of Class A factories
The specifications make it clear that it should not be set up!
The poster’s confusion might stem from the fact that a distribution room and a substation are not the same thing
According to Document No. 2020(3) issued by the National Security Commission, as well as the rectification directives issued by the Ministry of Emergency Management, such settings are not allowed
Interpretation of the Ministry of Emergency Management’s “Catalogue for Safety Classification and Rectification of Hazardous Chemicals Enterprises (2020)”: Substations shall not be located within Class A or Class B buildings
So what does \"adjacent construction\" refer to in this context?
As a supplementary note, it is a API manufacturing facility that follows the regulations for fine chemicals
“There are two forms of \"adjacency\": 1) two buildings being adjacent to each other, and 2) areas within the same building that are separated by partitions and thus considered adjacent. Here, \"adjacency\" refers to situations within the same building; whereas in the case of two buildings being adjacent to each other, fire separation distances need to be taken into account.
In short, it’s not allowed to be placed inside the factory building, that is, not within the projection of the main structure of the factory building； But: Note that several main conditions must be met simultaneously; one of them is that it should be a power transformation and distribution room serving this workshop ； The second is being adjacent, not within the main body’s projection ； Third, those below 20KV... and so on can be constructed ； Regarding the floor placement, in the case of oil-immersed types, they should be placed on the ground floor, while dry types or simple distribution cabinets can be placed on the second or third floor, as long as they are separated by firewalls. But in actual production, it is rare to find a three-story power distribution room located next to both Workshop A and Workshop B; in some cases, there is only a single-story power distribution unit adjacent to Workshop A and Workshop B ； The substation mentioned by the poster, located on the second or third floor, is likely situated within the area covered by the main workshop structure~~~~
As you can see from the attached diagram on the 10th floor, the layout is such that Class A areas are on both sides, while the power distribution room (with high-voltage transformers) is located in the middle in the Class C area. Strictly speaking, can’t equipment rooms like this be placed there either?
