Ship inverter shore power high and low voltage system 440V60Hz
Marine variable frequency shore power high-low voltage system system is a new product developed by our company. This series of products is specially used in outdoor and severe outdoor environments such as ports, docks, shipbuilding outfitting berths, ships, offshore drilling platforms, etc. Power supply occasions. This series of products adopts a fully sealed three-layer insulation pipe type full air-conditioning circulating heat dissipation equipment protection cabin design. The equipment inside the equipment cabin is completely closed and isolated from the external environment. The equipment cabin protection level reaches IP66, and the air-conditioning host protection cabin protection level reaches IP56. Any harsh outdoor environment requirements such as quayside, ship, drilling platform, etc. The appearance of the whole set of equipment is designed according to standard container containers, which is convenient for transportation and frequent movement. This series of products adopts the following proprietary technologies and characteristics of our company:
1.1. Adopt fully sealed and fully air-cooled three-layer thermal insulation mobile cabin technology. The cabin equipment is completely enclosed and isolated from the external environment, thereby ensuring that the cabin equipment is well protected as long as new.
1.2. Use the latest instantaneous voltage waveform control technology. The output voltage fluctuates ≤0.5V; the instantaneous change of the effective value of the output voltage (voltage sag and sag) ≤3% when 100% load suddenly increases / decreases, and it returns to the rated output voltage value within 0.5 fundamental wave periods.
1.3. Adopt a joint venture inverter third-order sine filtering technology. Greatly reduce the output impedance of the sine filter and improve the output power quality.
1.4. Using module drive signal master-slave synchronous parallel technology. Can realize any set of variable frequency shore power supply equipment without circulating current parallel operation.
1.5. The power switching device uses the SKIIP fourth-generation IPM high-power intelligent power module produced by German SEMIKRON company; the main control chip uses the latest generation of TMS320F28335—32-bit floating-point motor control digital signal processing chip from the United States TI Company DSP; drive transmission mode adopts 5MHZ fiber drive transmission; inverter modulation mode uses the latest SVPWM space vector pulse width modulation mode.
