Main switchboard
Main Switchboard
Product Overview
- Used in ships, offshore platforms, power stations, and other fields, this is a power distribution and control device independently developed by our company.
- Used for power stations with single or multiple generators operating in parallel, where the generators are powered by AC690V or less, 50Hz/60Hz, and have a power of3000KW or less.
- Used to receive and distribute electrical energy from ship generators, and to monitor, measure, control, protect, and manage generators, power grids, and loads.
- Main products include main switchboards and emergency switchboards.
Emergency Switchboard Functions
- Emergency generator control and power distribution functions.
- Automatically disconnects the main switchboard contact switch when the main switchboard loses power.
- Starts the emergency generator and automatically supplies power (power supply time meets the specification requirements).
- When the main switchboard power is restored, the emergency switchboard automatically returns to being powered by the main switchboard and stops the emergency generator.
Main Switchboard Main Functions
- Generator control and power distribution functions.
- Selection of three power station management modes: manual, semi-automatic, and automatic.
- Status indication, monitoring, and protection functions for generators and power grids.
- Automatic power restoration and sequential starting of important pumps.
- Fault detection and alarm for generator sets, automatic switching of faulty generator sets, and automatic shutdown.
- Automatic starting and paralleling of generator sets based on load, and disconnecting generator sets.
- Automatic frequency correction, always maintaining rated speed operation.
- Automatic proportional distribution of active load.
- Priority tripping function for non-critical loads.
- Heavy load inquiry and permission to start for large loads.
- Reverse power protection.
- Shore power interlock and control functions.
- Data sharing with other ship monitoring equipment.
- Selective protection to prevent large-scale power outages due to load short circuits.
