According to the SH/T3164-2012 lightning protection standards, the indoor instrument grounding system is applicable to various control rooms, field cabinet rooms, and field control rooms； The outdoor instrument grounding system is suitable for field instruments, field junction boxes, field cabinets, and analysis booths, etc. I would like to ask, what is the difference between an on-site cabinet and an on-site cabinet room? Are there cabinets placed outdoors?
An on-site cabinet room is a booth or room specifically designed to house cabinets. On-site cabinets are those that are installed directly outdoors; for example, the cabinets used to control compressors in a compressor plant can be considered on-site cabinets. Such cabinets must meet the requirements related to explosion prevention and dust control in their respective environments.
In other words, the on-site cabinet can share a room with the equipment, such as being placed in a corner; there’s no need to build a separate room or structure for it, right? Thank you.
It depends on whether the area is explosion-proof or not; another factor is the difference in load capacity
The requirements for on-site cabinets are higher. I’ve seen those used for positive pressure ventilation. Those in the room don’t need to be used, but some cottages have ventilation facilities
