With the continuous improvement and wide application of ship electrical technology, the degree of automation of modern ships is getting higher and higher, and higher requirements are placed on the ship automation power station system, which requires the switchboard to have perfect functions and easy operation. In addition to the functions required by the international and domestic classification societies, the switchboards of our factory can also be customized according to the specific requirements of different users, which is more in line with the user's usage habits. At present, the widespread application of ship automatic power station management system makes the distribution and management of ship electrical energy more functional. Especially the distribution board and the outer frame structure, our factory adopts the most advanced technology in the world, the whole screen is made of fold-up type, no welding structure process is used, and each unit of the starter combination screen adopts the drawer type, and each screen can be installed below 20KW Starter, 20 units. It is very convenient for disassembly, maintenance and temporary addition of components.
Main function:
Generator overload and short circuit protection/ Over-voltage, under-voltage and loss-of-voltage protection/ Reverse power protection/ Manual or automatic quasi-synchronous generator paralleling/ Manual or automatic generator frequency adjustment/ Motor voltage, current, frequency and power measurement/ Parallel Vehicle synchronization detection / shore power interlocking / wind and oil shaking / power grid insulation performance monitoring / fault alarm processing / ground fault protection (must be selected) / proportional distribution of active load in parallel operation / generator overload and grading unloading / emergency generator automatic start, Downtime
Automatic Power Station Main Features:
     When the power grid loses power, it can automatically start the diesel generator within 20 seconds and automatically close the power supply.
When the diesel generator is supplying power, if the grid load exceeds 90% of the capacity of the single unit, the standby diesel generator set will be automatically started and automatically closed and frequency-modulated to realize the parallel operation of the two units. When the power supply grid load exceeds 95% of the total capacity of the power station, the After 1 minute delay (adjustable time), the unimportant load is automatically unloaded. When the diesel generators are running in parallel, if the grid load is less than 40% of the capacity of the power station, the units connected in parallel will perform automatic load transfer and automatic unloading. , The heavy load inquiry function is disconnected from the power grid. The heavy load inquiry needs to be carried out before the heavy load starts, which is calculated by the automatic power station. If the capacity of the power station allows starting, a start command will be issued; if the capacity of the power station is small and the power station is running on a single machine, the standby diesel will be automatically started. generator set. The load can be started only after the automatic power station sends the starting command to ensure that the power grid will not cause overload tripping due to the sudden start of the high-power motor. The automatic power station has a self-checking function.
     The automatic power station has the extended alarm function stipulated in the AUTO-0 specification, and has a communication interface. All parameters are sent to AMS for automatic management. Sequential starting of important loads.

Purpose:
The switchboard is divided into two types: the main switchboard and the emergency switchboard: the main switchboard is directly connected to the main generator, and distributes the electrical energy of the main generator or the electrical energy from shore power to the remote secondary distribution device Or directly distributed to the electrical load; when the main power supply loses power, the emergency switchboard supplies power to some important equipment (emergency lighting, control devices, navigation and radio settings, etc.). The manufacture of switchboards conforms to GB11634-88 "Marine AC Voltage" General technical conditions for switchboards, GB11803-89 "Structure and basic dimensions of marine AC voltage switchboards" and the requirements of the National Classification Society "Code for Classification and Construction of Sea-going Steel Ships".
Structural features:
     The basic structural form of marine switchboard is split box type, screen type or frame assembled type. The box-type structure is suitable for small power distribution boards. It is made of thin steel plates after folding and welding. The screen type and frame assembly type structure are suitable for large and medium-sized switchboards, and the basic structure is assembled and welded by standard frame type special profiles. The installation of internal components adopts a detachable three-dimensional arrangement structure, which is very convenient for installation, use and maintenance; floor-mounted fixed installation, front and rear doors, and can be used for two-way maintenance. All-aluminum alloy structure can be made to reduce weight according to user requirements.

Ordering Instructions:
     When ordering, the user can provide the circuit diagram, outline dimension drawing and nameplate list approved by the ship inspection; the user can also provide the single line diagram and main technical requirements, our company can provide the user with the principle design and construction design And after the user's approval, the production will be carried out; when the user has special requirements for spare parts, they should be put forward together when ordering.
