Is it possible to set up a low-voltage switchroom beneath the circulating water station?
Thread Content
Beneath our circulating water system, there is a space 11 meters deep – plenty of room available. We plan to set up several chemical dosing rooms, as well as a small low-voltage power distribution room to supply power to the low-voltage motors used in the chemical dosing equipment, electric valves, and pump systems. However, the design institute states that the circulating water system is an essential facility, and it is not allowed to build any more electrical distribution rooms below it. Is there any standard or regulation supporting this?
The design and installation of electrical facilities require strict compliance with the relevant regulations and standards in the electrical and construction industries. Regarding whether a low-voltage power distribution room can be installed in an underwater environment, the following three main standards should be referred to: 1. \"Code for Electrical Design of Buildings\" GB 50054-2011: This standard stipulates that electrical equipment rooms should be located as independently as possible, and they should not be placed in areas where there may be sources of fire, nor in areas that could be exposed to water. 2. \"Code for Design of Distribution Equipment and Distribution Lines in Electric Power Engineering\" GB 50053-2013: This standard specifies that distribution equipment should be installed in dry and well-ventilated areas, and must not be placed in locations where there are flammable, explosive, or toxic substances. 3. Code for Electrical Design of Industrial and Civil Buildings GB 50092-2009: This code stipulates that the power distribution room should be located in a place free from leaks, corrosive gases, and dust. Based on these standards, there may be the following issues with installing a low-voltage power distribution room underwater: – Humidity control: Installing a power distribution room underwater can present challenges related to humidity control, which may lead to a decline in the performance of electrical equipment and even cause electrical failures. - Safety risks: Recirculating water equipment is a critical facility; any leakage could lead to short circuits in the electrical equipment within the switchgear room. The leakage current may cause electric shock accidents, and in severe cases, even fires. - Maintenance difficulties: Installing a power distribution room underwater can increase the difficulty of maintenance, as special equipment or tools are required for carrying out maintenance and repairs. Therefore, the recommendation from the design institute is correct; it is not advisable to locate a low-voltage distribution room under circulating water. If you truly need to power equipment such as chemical dosing units, electric valves, and water pumps, you may consider installing power distribution equipment on the ground or in other safe locations. If there are any other questions, you can seek advice from professional electrical engineers or electrical designers. .
