◆GB11634-2000 Marine AC low-voltage switchboard General technical conditions
◆Used in ships, offshore platforms, power stations, etc., used to control, monitor, protect generators and transformers, and network power Assignment, etc.
◆It is used in the system of AC690V, DC380V and below, 50Hz/60Hz, and the power of single generator is 12KW-1600KW.
◆ Protection level is divided into: IP23 (indoor), IP44 (indoor humid environment).
◆The panel material is high-quality cold-rolled steel plate (can be customized for aluminum plate), and the surface is electrostatically sprayed.
The cabinet is a modular combination frame type.
◆Internal components mainly use ABB, Schneider, Siemens, Mitsubishi, Omron and other internationally renowned brands and domestic well-known brand products in line with national standards.
According to the needs of customers, the corresponding functional modules can be integrated with different automatic power station management systems for different ships, so that the main distribution board can allocate and manage electric energy more rationally, economically, practically and intelligently, and realize the unmanned cabin.
