首先结论是可以的。但是IP等级要高于23.
1. From DNV rules: The switchboard rooms and similar spaces covered by this requirement shall have a fire extinguishing system suitable for use on high voltage equipment. This will in general imply use of a gas based fire extinguishing system unless that it can bedocumented that other systems (water mist based on potable water) has equivalent fire fighting performance (small fires/enclosed cabinets) and do not damage the electrical equipment.
2.From manufacture: SEM-SAFE® high-pressure water mist is very suitable for the protection of electronic rooms, switchboard rooms and other rooms with sensitive electronic installation. The system has been tested and installed in computer rooms, server rooms and switchboard rooms
without damaging running electronic equipment. The minimum protection rating of equipment installed in the room is IP23.
Note:
0 Non-protected
1 Protected against dripping water
2 Protected against dripping water when tilted up to 15o
3 Protected against spraying water from above up to 60o from vertical
4 Protected against splashing water
